What are the processing techniques for automotive stamping parts?

What is the manufacturability of stamping parts? The processability of stamping parts includes whether the properties and dimensional accuracy of stamping parts can be used in stamping processing methods; can they be manufactured by simple and convenient stamping process methods. The processing technology of automobile stamping parts is general. Mainly based on drawing process, bending process and punching process, a good stamping process can save materials and procedures, and the mold is easy to process, long life, stable product quality, and good benefits; 1. Drawing process, drawing The fillet radius R between the flange and the side wall of the part and the fillet R between the bottom and the side wall should be enlarged as much as possible. The fillet radius is large, which can make the part easy to be drawn into shape. The drawn part should be as symmetrical as possible or adopt a left-right symmetrical drawing. Pieces; so as to be double-drawn, and then cut into two pieces; 2. Bending process; when bending, the hole should be prevented from deforming, and there should be a proper distance between the edge of the hole and the bend to avoid the deformation of the hole, otherwise, it should be pressed first Punching after bending; the length of the flange should not be too small; the press-bent parts should try to consider the positioning of the process hole and double bending to change the stress; Scrap, straight or curved joints should have proper rounded corners to facilitate the manufacture, maintenance and use of molds; avoid long and narrow shapes; aperture and hole spacing should meet the minimum size requirements; recommended article: the main view of the stamping part die any request?
