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.

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.

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.
