【Abstract】: Automotive precision Stamping parts stamping process is generally based on the drawing process, bending process, punching process; 1, automotive precision stamping parts drawing process: drawing parts flange and side wall fillet radius R and the bottom and side wall fillet radius R should be enlarged as much as possible, the fillet radius is large, can make the parts easy to draw forming, drawing parts should be symmetrical as far as possible or to take the left and right symmetry of the drawing parts; in order to become a double drawing, and then Cut into two pieces.

Automotive precision stamping parts stamping process is generally based on the drawing process, bending process, punching process:

1.Automotive precision stamping parts stretching process: stretching parts flange and sidewall corner radius R and the bottom and sidewall corner radius R should be enlarged as much as possible, the corner radius is large, can make the parts easy to stretch forming, stretching parts should try to symmetrical or take the left and right symmetrical stretching parts; so that into a double stretching, and then cut into two pieces.

2.Automotive precision stamping parts bending process: bending should prevent the deformation of the hole, hole edge and bending should be an appropriate distance to avoid the deformation of the hole, the length of the curved edge is not easy to be too small, the bending parts should try to consider the positioning of the process holes and into a double bending, in order to change the force situation.

3.Automotive precision stamping stamping process: in the shape of the material should try to make reasonable sampling, reduce waste, linear or curved joints should be appropriate rounded corners, which facilitates the manufacture of molds, maintenance and use.
