The principle of the high-speed roller feeder is to feed the feeder by the output shaft of the punch. Therefore, the puncher must be equipped with a roller feeder. The puncher must have a drive shaft. The high-speed roller feeder eccentric disk mount is fixed on the drive shaft. The eccentric disk rotates to drive the pull rod. The pull rod is transmitted to the drive shaft of the feeder and passed through a single bearing. The lower drum of the high speed roller feeder realizes feeding. The feed length of the roller feeder is adjusted by the eccentric disk.
 

The operation is more convenient, and the waste of the scraps occurring in the process is avoided. Compared with the traditional single-punch blanking die processing method, the progressive blanking processing can increase the production efficiency by 2.5-6 times, and can save 10-20. % raw materials.

Moreover, since the raw material for the processing of the feed-in and blanking is made of the coil material, when the punch feeder and the blanking die are used together, the automatic feeding is realized, and the scrap is removed by the cutter, so that the operator can collect the waste.

The blanking progressive die is provided with a plurality of blanking punches and corresponding recesses on the upper and lower molds respectively, and in particular, a plurality of blanking materials can be simultaneously punched in one plane by means of an equidistant front and rear staggered distribution.

The distribution of the stamping parts can ensure that the pressure is balanced during the pressing of the coils, and the problem of inconsistent shape of the blanks due to uneven force is prevented, which also ensures the accuracy of the feeding of the feeder.
