How to deal with the cracked metal stamping parts

When stamping metal parts are processed by stamping factories, various defects will occur, such as the cracks of metal stamping parts that often occur during the production process. Next, Precision will give you an analysis of the countermeasures after the metal stamping parts crack. Anti-cracking countermeasures: In order to better avoid cracking, it is necessary to take effective countermeasures from various aspects of the structure of the cover, the forming process and its stamping die. (1) In terms of the structure of metal stamping parts, the countermeasures that can be adopted are: each arc half-warp is larger, the slope shape is shallower in the drawing direction, the deep layer is more symmetrical, the shape is as simple as possible and the transformation is as possible Wait slowly. (2) At the deep drawing process level, the key countermeasures that can be adopted are: the drawing position makes the total contact area between the mold base and the blank as large as possible, the effective stripping surface and the edge strip force make the pressure surface position The frictional resistance is well-proportioned, the deep drawing layer is reduced, the processing technology hole and the processing technology wound are opened. (3) On the stamping die: the design scheme can be used to effectively draw the bead, the large mold arc is selected, and the gap between the mold seat and the cavity is effective and other countermeasures.
