Mandrel Expansion Decoiler and Leveler Machine Coil Processing Equipment

The feeder is an indispensable equipment for automatic continuous production with a punching machine. It can reduce the production cost of stamping processing, improve the processing efficiency and improve the quality of stamped products. Therefore, it has been widely used in the stamping industry.

The commonly used feeders for punching machines mainly include air feeders, roller feeders, NC servo feeders, clip feeders and gear feeders. The clip feeders and gear feeders are special feeders, one for For high-speed stamping of narrow sheet metal, one is a special feeder for processing of silicon steel sheet.

When the stamping owner purchases the feeder, it is necessary to clarify the characteristics of the stamping process, clarify the width, length, thickness and precision requirements of the stamping process, and comprehensively consider the later development. It is necessary to comprehensively consider the later use, maintenance, maintenance, repair, etc. For each cost, combine the above points to select the type of feeder, and then choose a strong manufacturer to purchase.

Feeder performance and advantages and disadvantages:
1. Air Feeder: This is the lowest-priced feeder equipment in the stamping industry. It uses cylinder clamps to complete the feeding action. It is easy to install and allows customers to automate with minimal investment.

Disadvantages: The feeding accuracy is not high. It is easy to damage the material by clamping the moving material. The failure rate is high (O-ring is easy to damage and the feeding is not accurate). It requires frequent maintenance and high maintenance and repair costs. It is mainly suitable for feeding accuracy. Processing occasions where the requirements are not high and the feeding speed is not fast.

2. roller feeder: no need to use additional power, gas source, the output shaft of the punching machine to provide feed power, feed speed and punch synchronization performance is good, is currently the most popular and cost-effective feeder equipment.

Disadvantages: The principle determines that the type of punching machine is limited (there must be an output shaft for punching), and the feeding length, width and thickness are limited (width is less than 700mm, thickness is less than 3.5mm, feeding length is less than 300mm), and the machine is used in steps. Adjustments are cumbersome and time consuming.

If the workpiece has excessive burrs or unusual noise during stamping, the mold may be passivated. The CNC feeder checks the punch and the lower die. When the edge is worn to produce an arc with a radius of about 0.10 mm, it is sharpened. Practice has shown that frequent micro-sharpening, rather than waiting for non-grinding, can not only maintain good workpiece quality, reduce punching force, but also prolong the life of the mold by more than one time.

3.The main shaft adopts ø140's 45# seamless pipe. After quenching and tempering treatment, the long-term load will not be deformed. Operational safety: The transmission parts such as the transmission belt and the rotating shaft are all equipped with protective covers to ensure the operation of the operators and the safety of the upper and lower coils.
