However, during the stamping process, coils need to be transported, and a feeder is required.

[0003] However, during the use of the current stamping feeder, the shaft size of the fixed coil is fixed, while the inner diameter of the coil is different, which makes it inconvenient to adjust and fix it according to the inner diameter of the coil. At the same time, since the rolled material is heavy, the stamping feeder can only bear the weight through the conveying bearing. In the long run, the output shaft of the stamping feeder will sink and age quickly. Utility Model Content
