The blanking clearance of precision metal stamping parts refers to the gap between the punch and the die in blanking.

The distribution of the material flow resistance along the die orifice has a direct relationship with the stretching depth.

Make the punch contact the blank area large. The larger the contact surface, the smaller the Angle between the contact surface and the horizontal surface.

Selection of raw materials: in the metal stamping processing, will use many different raw materials, according to the density of raw materials...

Winding the waste with the receiving drum, in fact, the appearance of the receiving drum is almost the same as that of the strip steel drum.

The number of processes of precision stamping workpiece mainly depends on the complexity of its structural shape, the number of bending angles, the relative position and the bendin

The sheet size is too short, the material activity is too fast when forming, and the drawing bead does not play an effect.

Deoiling must choose weak alkali deoiling, can not contain sheet alkali ingredients, TAL to operate at around 15POINT, pH can not exceed 12.

Before starting the machine, check the bending equipment used to confirm that there is no problem before starting the machine, so as to avoid danger...
