Fine Stamping FORD handbrake part

In blanking protruding moulded into the material at the same time, using the back pressure of ejector, the material compaction, and using minimum clearance die with rounded corners and eliminates the edge stress concentration, so that the shear zone of the metal in the three-way compressive stress state, to eliminate tensile stress in the district, to improve the material of plastic, fundamentally prevent the ordinary cutting phenomenon of bending, stretching, tearing apart, Make the material along the edge of the concave die shape, in the form of pure shear is blanked into parts, so as to obtain high quality smooth, smooth shear surface.

The main factors that affect the fine blanking parts:

1) manufacturability of parts structure;
