Development experience of metal stamping terminal

- Aug 20, 2018 -

The characteristics of the metal stamping terminal of the control group:

   1. Reserved finishing material width 0.035mm (equivalent to 11.7% of plate thickness 0.30mm)

   2. The R angle is R0.50mm (equivalent to 166.7% of the plate thickness 0.30mm)

   3. The unilateral shear gap between the punch and the knife edge is 0.005mm (1.67% of the plate thickness)

   4. The punch is polished (Uro)

   5. First, the rough embryo is cut, and then the finishing is finished. There is no other finishing station near the plate.


Features of TEST2 (0.5P R/A FPC):

   1. Reserved finishing material width 0.06mm (equivalent to 30% of plate thickness 0.20mm)

   2. The R angle is R0.050mm (equivalent to 25% of the plate thickness of 0.20mm)

   3. The unilateral shear gap between the punch and the knife edge is 0.004mm (2.0% of the plate thickness)

   4. The punch is not polished

   5. Before the rough embryo and finishing, there is a material station near the plate.

      Plate stability is poor.
