Q
How To Choose Suitable Coil Straightener Feeder Machine?

A

How to choose suitable coil straightener feeder machine The modern metal stamper must build capacity and flexibility into his coil-processing and stamping machinery to meet the challenges presented by evolving product lines and new customers and markets. These overlying challenges present a substantial obstacle when specifying a new straightener. The stamper faces fundamental decisions early in the game related to the ability of the straightener to handle a variety of applications.For example, a straightener with seven 100mm dia. work rollers located on 170mm centers, and given adequate power and gears, will straighten 6mm.-thick cold-rolled steel. The same machine will have minimal effect on 1.2mm. cold-rolled steel. Likewise, a straightener designed with seven 76mm dia. work rolls located on 127mm. centers will effectively straighten the 1.2mm thick steel but will lack the horsepower and roll strength to process 6mm material. If an application calls for this type of variation in material thickness, a fundamental decision must be made in regards to the cost effectiveness of building a special machine to meet the full spectrum of needs, versus building a standard machine that will provide optimum straightening at either the light-gauge or heavy-gauge end.Stampers also must consider the maximum width of the material and machine, and the range of material thicknesses to be processed. As straightener width increases so does the tendency for work rolls and journals to deflect under load, thus impacting the machine’s ability to process material with a defined thickness and width. This deflection can result in a loss of contact-surface area, decreased straightening efficiency, material slippage or broken work rolls.Note: Do not request a machine capable of processing wide material without considering the effect that narrower material will have on the machine. A machine rated to straighten 1200mm wide by 3mm -thick steel may struggle to process the same thickness of steel, but as 300mm wide strip. The cross section and strength of the 300mm material is substantially less than the 1200mm. material, but the straightener rolls most likely will experience a greater amount of deflection when running the narrower material, as the forces and stresses are concentrated at the roll center. This area is furthest from the end journals and bearings that support the rolls. (A single row of backup rolls would allow the machine to efficiently straighten the narrower material.)
Q
What is the advantages of compact coil feeding line decoiler straightener feeder?

A

What is the advantages of compact coil feeding line decoiler straightener feeder? Most metal raw materials used in sheet metal stamping companies are the coil type. A metal coil must be uncoiling and levelled to eliminate internal stress, then fed into the stamping press machine. The loop type coil feeding lines usually require two or more independent equipment to be used together, comparing with loop type coil feeding line, the combined decoiler straightener feeder coil feeding line has many advantages:1. Modular control, simple coil handling operationA compact coil feeding line is not only a simple combination of uncoiler, straightener, and feeder but also highly integrated control in operations. The hydraulic station, coil car, uncoiling motor, spindle and inverter, straightener part, servo feeder motor are connected with the PLC modular system and controlled by one touch screen, which is quite convenient for operators.2. High precision straightening and feeding performanceFor a loop type coil feeding line, there will be a material loop between each two equipment, means all of them need an inverter for speed control, even so, the running match will not be fully synchronized, which will affect the precision of feeding. A decoiler straightener feeder coil feeding line can synchronize these three parts, has control of PLC closed-loop system, which ensure a high servo feed accuracy.3. Wide range of metal coil processing applicationsThe application range of decoiler straightener feeder coil feeding line is much wide than other types. It can handle high strength steel and also normal steel in high thickness. It can handle steel thickness up to 12.0mm coil width up to 1800mm with high precision straightening performance. A compact decoiler straightener feeder coil feeding line is necessary for the high strength steel stamping in automotive, construction, aerospace or electrical appliance manufacturing.4. Save workspace, easy installation and maintenanceThe compact coil feeding line is easy to install, which can enter into mass production in a short time. Without a long material loop, the coil feeding line length is usually no more than 5m, some models such as GLK2 is only 2.5m length, which will save workplaces of stamping room. With international brand core components, automatic lubrication system and self-inspection procedures, the compact coil feeding line have a very low failure rate and easy to maintenance.Compact coil feeding line (Servo straightener feeder with uncoiler) is HongEr’s major product: GLK2 series for thin material handling, GLK3 for medium thickness steel coil processing, GLK4 for the thick coil thickness up to 6.0mm, GLK5 series for heavy-duty steel thickness up to 9.0mm, and also GLK-H series for high strength steel stamping. HongEr also provides customized coil handling solutions according to specific sheet metal coil processing.
Q
How to solve the feeding accuracy problem?

A

What will cause the inaccurate feeding of the servo feeder? How to solve the feeding accuracy problem? Inaccuracy feeding occasionally happens in sheet metal coil feeding process. There are various reasons that caused the feeding accuracy problem, HongEr summarized the main causes and solutions for the inaccurate feeding of NC servo feeder.Uneven feed roller pressureThe sheet metal coil will be always biased in one direction because of the uneven feed roller pressure, which will cause inaccurate feeding.Solution: If the coil sheet always biased to the left, it means the pressure on the left is too large. At this time, turn the left pressure adjustment nut counterclockwise to reduce the left spring pressure until the material runs back to the correct position, or turn the right pressure adjustment nut clockwise to increase the right side spring pressure.Material deformationThe coil material is too soft and easy to deform will also cause inaccurate feeding, such as copper, aluminum. Excessive pressure on the upper roller causes soft material deformation and bias. The coil sheet will sometimes go to the left side and sometimes go to the right side. Solution: Please unplug the lower tube of the release air cylinder and fold it up. If the material is still deformed, please rotate the two pressure adjustment nuts counterclockwise to release the pressure. It’s very important for us to know your coil material kind before produce a servo feeder machine. Please confirm your feeding material with our sales before purchasing. Coil material uneven or burrsThe thickness of the two sides of the material is different or the material has severe burrs, will cause the material to always be biased to one side when feeding.Solution: Adjust the pressure adjustment nut and change the inlet locating wheel to the inlet locating plate. Otherwise, it can only be solved by replacing the materials.Machining or assembly failureWrong machine processing or assembly will also cause inaccurate feeding. This problem doesn't happen in HongEr servo feeders yet, if any fault of our servo feeder, please contact us now to solve the problem in time.
Q
What's the Principle of roller straightening?

A

About Straightening in punch and shaping technology Principle of roller straightening 1. Metal sheets up to more than 50 mm in thickness and metal strips down to the thinnest sheets are straightened in straightening machines before further processing.2. The sheets are subjected to a process of bending back and forth between rollers arranged as shown above with decreasing curvature. 3. The number of straightening rollers depends on the required straightening result.4. Hardest to straighten are sheets that have unevenness not only in the rolling direction, but also transverse to it. In this case at least one precision straightening machine is required and the straightening process may need to be repeated several times to eliminate the multiaxial tension states in the sheet.5. The best straightening results are achieved on a precision straightening machine designed with extremely limited stretching and equipped with roller deflection. Straightening machine drive 1. All rollers are driven together by the distributor gear2. Drive via three-phase motor, which has a frequency inverter as standard equipment. Depending on the application, a servo drive may also be used.3. Strip straightening machines are constructed with a run-through speed of up to 120m/min for strip supply operation for pressing.4. Part straightening machines are designed for a maximum of 20 m/min How can i achieve good straightening result 1. Good initial material2. The smallest possible straightening roller diameter+ roller distance3. Straightening machine with low strain and bending4. At least 9 straightening rollers to straight coil curvature 5. At least 15 rollers for flat straightening, optimally 19/21 pieces 6. Straightening rollers must be supported
Q
What Is Progressive Mould/Continuous Die/ Injection Tooling In Metal Stamping Line?

A

What Is Progressive Mould/Continuous Die/ Injection Tooling In Metal Stamping Line? Conception:The progressive die (also called continuous die) consists of multiple stations, each of which is associated in sequence.The machining process completes a series of different stamping operations in one stroke of the press. After the completion of one stroke, the punch feeder moves the material forward according to a fixed step, so that multiple processes can be completed on one pair of molds, generally punching, blanking, bending, trimming and deep drawing, etc.Function:1. Progressive die is a multi-task die. It can include multiple processes such as punching, bending and drawing in a pair of molds, which has high productivity;2. The progressive die operation is safe;3. Easy to automate;4. Can be produced by high speed punching;5. It can reduce the punching, the area of the site, and reduce the transportation and warehouse occupation of the semi-finished products;6. Parts with extremely high dimensional requirements should not be produced by progressive die.Requirements:1. The parts are small;2. Large batch size;3. The material is thin (like 0.08~2.5mm);4. The material is softer;5. The shape is more complicated;6. Valuable metals are not suitable (low utilization);7. The accuracy is too high (IT10 or below).What is continuous die?Continuous die means that the press uses a strip-shaped stamping material in one press stroke, and simultaneously performs a cold stamping die of multiple stamping processes on several molds with several different stations. Move once with a fixed distance until the product is finished.Application:Whether a stamped part adopts a multi-station continuous mode or not? We should consider the following aspects:(1) Design, fabrication and maintenance of continuous moldsThe structure of the multi-station continuous mode is quite complicated, and the manufacturing precision is much higher than that of the general mold. After each batch production, it must be repaired and sharpened, and after passing the test, it can be put into storage for use. Some small punches must be replaced in time after the insert is worn or damaged. Bending, deep drawing, forming multi-station continuous die, when sharpening the edge of the punch and die, correct the relative height of other parts at the same time. The bending, deep drawing, and forming multi-station continuous die have different heights of the punch and the die, so the relative difference of the original design must be maintained after sharpening. There must be a certain level of maintenance workers and the necessary precision equipment.(2) Applicable pressesPresses used in continuous mode should have sufficient strength, stiffness, power, accuracy, large work surface and reliable braking system. The stroke of the punching machine should not be too large to ensure that the continuous mold frame guiding system does not disengage when working. Generally, it should work below 80% of the nominal pressure of the press. In the multi-station continuous mode, the detection mechanism of the strip feed failure should be set. After the detection mechanism sends out the signal, the brake system must be able to stop the press immediately to avoid damage to the mold or the machine tool.(3) Good processed materialsIn the continuous die-punching process, intermediate annealing cannot be performed, which is not convenient to increase lubrication during processing. Therefore, the mechanical properties of the stamping materials must be relatively stable. For each batch of materials entering the factory, it must be tested and inspected according to regulations; The width and thickness tolerances of the strip, as well as the straightness of the stock edge, are high because they will directly affect the punching effect and the feed of the strip.(4) Stamping parts should be suitable for multi-station continuous die-punching1. The production and batch size of the parts to be processed should be large enough.2. Multi-station continuous mode is lower in material properties than other molds.3. The accuracy of feeding and the cumulative error between each step will not reduce the accuracy of the parts.4. The shape of the part is complicated and it is not easy to position after punching. It is most ideal to use multi-station continuous mode.

Q
How to choose the most suitable punch feeder?

A

How to choose the most suitable punch feeder? The punch feeder is an automatic equipment for stepping and conveying materials for punching, and it is also an essential auxiliary equipment for automatic stamping production. With the increasing scope of stamping processing, the stamping process is becoming more and more complex, and the types of feeders are increasing. Many stamping owners who are planning to purchase for the first time are often overwhelmed by the variety of feeder models. They don't know how to buy, Honger Machine Equipment as a professional punch feeder manufacturer, here to explain the purchase points of the feeder. The best choice for a most suitable feeder is not based on price, but to firmly grasp the four main points: 1. Find out the basic properties of your materials used in stamping production. It mainly includes raw material， material‘s hardness (yield and tensile strength), maximum material width, material thickness range, special treatment on the surface, and surface degree requirements during stamping. 2. Identify the needs of the stamping process. It mainly includes how many tonnage punches that you use, the brand of your punches, your stamping moulds/dies, stamping speed requirements, feeding length and whether it is often required to change the length, the accuracy requirements and the actual daily output requirement of your production. 3. There is a need for a basic understanding of punch feeder. Air FeederThe earliest feeder type, the advantage is that the stamping owner can realize automatic produce under the minimum investment, mainly used for stamping speed, punching speed is not fast, and there is certain stamping experience factory. High Speed roller Feeder At present, the most used feeder type, the advantages are high feeding precision, high speed, no additional energy supply, and extremely low failure rate. It is mainly used for material widths up to 500mm and feeding length within 300mm and the punch presses with output shafts. NC servo feederThe most widely used feeder type, the advantages are wide range of use, easy operation, high feeding precision, multi-stage feeding, mainly used for stamping products with wide material width, long feeding length. High Speed Gripper Feeder It is a high-speed punch-specific feeding device. The advantages are fast feeding speed (can be fully synchronized with high-speed punching) and high precision. It is mainly used for high-speed stamping of ultra-thin materials such as connectors, lead frames and connectors. CAM Drive FeederIt is a special type of feeding equipment, mainly used with high-speed punching machine, producing transformer steel sheet, motor stator and rotor, EI sheet and other punching products. 4.Select a truly reliable punch feeder manufacturers, integrated your own budget, select models and then purchase. The manufacturer with real strength is more guaranteed in the quality and service, which can make the subsequent cost less. However, in the selection of the model, it still needs to take into account the use, maintenance, and maintenance costs.
Q
What is the role of the feeder pilot releasing device?

A

What is the role of the feeder pilot releasing device? Many customers are confused by the pilot release device of the feeder when purchasing the feeders for punch machine. They often asked us what is special about this device. HongEr Machine Equipment answers it here:The feeder is mainly used with the continuous die of the punching machine to realize automatic high-speed production. The initial feeding accuracy will be very high, but when the multiple feedings accumulate, the cumulative error will be generated, which will affect the precision of the stamping production. At this time, the lifting device on the feeder is needed. It is used with the die guide pin to eliminate this cumulative error. The principle is that each time the feeder feeds (usually feeding in the rising phase of the punch slider), the punch will punch the hole in the material consistent with the guide pin. Down, the tip of the guiding pin is inserted into the material guiding hole, then the loosening device controls the feeder to not clamp (completely loosen the material), and the feeding guide pin is used to correct the feeding error of the feeding machine. Therefore, when the stamping die has a guiding pin, the feeder can be equipped with a relaxing device to correct the error and achieve high-precision feeding; if the die has no guiding pin, the feeder cannot be relaxed.In order to deepen your understanding of the feeder pilot release device, here are the pilot releasing devices of the three commonly used feeders:1. The air feeder is equipped with an R-type electromagnetic valve to control the fixed splint for instant relaxation and achieve high-precision feeding. When the mold guiding pin is inserted into the guiding hole, the guiding rod touches the micro switch to generate a relaxation signal, which is transmitted into the R-type electromagnetic valve, so that the fixing plate is instantaneously relaxed.Note: R type electromagnetic valve requires independent power supply, and there are solenoid valves of 24V, 110V and 220V.2. The roller feeder is equipped with a pilot release device. The pilot release device is mounted on the punch slider. When the slider is lowered and the tip of the positive guide pin is inserted into the guide hole, the loose screw hits the outer edge of the bearing, so that the passive wheel leaves the material for 0.2-0.5mm, at this time the feeder completely releases the strip to achieve relaxation.Special attention: the loose screw must touch the outer edge of the bearing to avoid damage to the screw or the bearing seat; the loose bracket must be shaken during the use of the feeder, and the shaking amount must be greater than 0mm, less than 5mm.3. The NC servo feeder is divided into pneumatic NC and mechanical NC according to the different pilot release devices. Pneumatic NC feeder, pneumatically released, realized by cylinder and electromagnetic valve. The principle of action is similar to that of air feeder. When the tip of the die guide pin enters the guide hole, the punch gives the feeder a releasing signal. The roller rises and completely relaxes the material. The mechanical NC feeder and the roller feeder use the same relaxation device.

Q
How to Choose the Most Suitable Stamping Automated Production Lines?

A

HongEr Machine specializes in metal stamping machines such as press, feeder, straightener, decoiler, and most importantly, dies.The automatic metal stamping production line mainly includes: progressive die stamping, multi-station stamping, and tandem stamping. Due to their respective characteristics, they are used to produce different automotive sheet metal parts, with their unique advantages in automotive automation. The efficient production system plays a huge role.Here we will compare and analyze the characteristics of the three automated stamping production lines, and explain the selection of the production line according to its characteristics. Therefore, it is convenient for each business to select automatic production lines according to the characteristics of its own parts. With the rapid development of the automobile industry, the metal stamping industries have also flourished. In order to adapt to the ever-increasing output, various automated production lines have emerged, and with the characteristics of the products, the different production methods are given. Companies select different production methods according to the characteristics of its own products. The production lines are classified into: progressive die stamping, multi-station stamping, tandem stamping, and a brief analysis of the characteristics and selection methods of each production line. Selection factors for stamping automated production lines:Generally consider the following factors to select the type of press lines:(1) Product material: including material type, formability, hardness, etc., to measure the choice of coil or sheet forming.(2) Material thickness: Consider the thickness and materials together to select the tonnage of the press machine and the feeding machines.(3) Monthly production requirements: assess production capacity for the selection of automatic line types.(4) The volume and shape of the stamping product: Through the modeling complexity and product quality requirements, the mold design method and the corresponding stamping automation production method are comprehensively considered. Common stamping automation production line types:Progressive die stamping production line(1) Overview: The progressive die automatic stamping production line is a production line that uses progressive die stamping. It is generally composed of decoiler, straightener, feeder, punching machine, progressive die, and automatic cutting line to realize decoiling, straightening, feeding, oiling, stamping, blanking and collecting of the coil material.The important part is progressive die, which consists of multiple stations, and some can be as many as more than 20 stations. Each station is sequentially connected in order to complete different processing contents, such as punching, trimming and turning, edge, shaping, blanking process, etc. A series of different processing are completed in one stroke of the press. After the completion of one stroke, the feeder moves the strip in the forward direction according to a fixed step, so that multiple processes can be completed simultaneously in one punching. (2) Features: The progressive production line is highly efficient, and can usually reach up to 30 s.p.m.A. High productivity. The progressive die is a multi-tasking die, which can include various processes such as punching, bending, and drawing in a pair of molds, and has high productivity. B. The line is easy to automate. Automated operation can be realized from loading, decoiling, straightening, feeding, stamping and blanking, thereby reducing labor costs, improving production efficiency, and preventing abnormalities caused by inconsistencies in manual operations.C. Can be produced using high speed presses. Depending on the product features, high speed presses can be considered for higher productivity.D. Safe operation. The progressive press equipment has safety gates that separate the work area from the personnel operation area to form a relatively closed work area, providing safety for high-speed production.E. Saves production space. Just one press machine is needed in the production line to complete the production of a metal product. It has a small footprint and also simplifies the transportation state detection of the bottom and semi-finished products, and has high safety.F. Material utilization is not high. In order to ensure the continuity of the material and the requirements, in order to ensure the stability of the feeding, it is generally necessary to ensure the even distribution of the contents of the process state, sometimes at the expense of wasting parts of the material, so that high material utilization cannot be achieved. Multi-station stamping automation production line(1) Overview: A multi-tonnage press table is equipped with multiple (usually 4~5 pairs of molds) independent working position mold production lines, using the unloading hand or the unwinding feeder to feed, using the automatic feeding rod for process parts transfer , use the automatic conveyor belt to collect the off-line products. (2) Features.A. The material can be a coil material or a sheet material, which has great flexibility and increases material utilization.B. Uses automatic rod feeding, which is slower than the progressive die production line and faster than the traditional tandem production line, which can achieve higher production efficiency.C. Can equip with the loading and unloading sensor, double material detection, pinch sensor, in-mold sensor, etc., to control the position and state detection of the material and the production parts, and is highly safe.D. There is a high requirement for the feeding height and the feeding direction of each station. In order to ensure the stability of the feeding, it is generally necessary to ensure the consistency of the process steps in each process. Tandem stamping automation production line(1) Overview: Arranged by multiple presses in series into an automated production line. Each presses is mounted with a pair of dies (ie, one step of the production process), and the loading is performed by an automatic robot arm.(2) Features.A. It has a wide application range and can be applied to the production of various stamping parts. It has no high requirements on the size, shape and thickness of stamping parts, and can be applied to the production of large-sized cover parts with high flexibility.B. Production efficiency is low, due to the use of mechanical arm feeding, the pressing speed can not be higher, compared with the progressive production line and multi-station production line, the production efficiency is lower.C. Is convenient for mold repair and debugging. Each pair of dies on each press are independent, thus the working parameters are independent, and the maintenance and debugging of each mold process can be carried out independently without affecting each other.D. Occupying a large production space, a traditional tandem production line generally includes 4 to 5 presses and covers a large area. Selection and application of stamping automation production lineProgressive Die Stamping Automated Production Line: Considering the process characteristics that various processes are distributed on a single continuous strip and the high efficiency in metal stamping, it can be applied to the production of small parts on the car body and can meet a high supply. Multi-station stamping automation production line: It can be applied to the rapid production of medium-sized parts, for example, the beam parts that are not easy to be deformed, the symmetrical parts with complex left and right common-mode shapes, and the products that can be clamped by the clips on the automatic rod. Tandem stamping automation production line: Because its various processes are independently distributed in each press, the production line has the highest flexibility and is suitable for large-sized coverings with complicated production processes, which is conducive to the commissioning and independent production of individual processes, and is convenient for quality control of products. The selection of each stamping automation line can be based on two main requirements: High-volume and high-flexibility parts require high-efficiency, high-volume automated production lines. If the parts are complex and require high production processes, a flexible production line can be selected. With its own characteristics, the stamping automation production lines have been applied to major automobile factories, providing a strong guarantee for the development of the automotive industry and the rapid growth of automobile production. The analysis and understanding of the stamping automation production line facilitates the selection of stamping parts production methods, making full use of the advantages of their respective automatic lines to serve the automotive field.
