Description

Technical Field

[0001] The utility model relates to automobile component processing equipment, in particular to a punching equipment for an automobile suspension swing arm bushing set. Background Art

[0002] The automobile suspension arm bushing kit is an important part of the automobile. The processing of the automobile suspension arm bushing kit requires a series of steps such as cutting, stamping, punching, welding, and grinding.

[0003] In the prior art, the stamping and punching of the outer shell of the automobile suspension arm bushing kit are generally carried out separately, that is, the automobile body sheet metal is first stamped and formed by a stamping die, and then the outer shell of the automobile suspension arm bushing kit after the formation is taken out and punched at the required position by a punching mechanism, thereby reducing the production efficiency of the automobile body sheet metal parts. Moreover, the outer shell of the automobile suspension arm bushing kit cannot well press and limit the upper and lower surfaces of the automobile body sheet metal parts during punching. Therefore, when the punch column contacts the automobile body sheet metal parts for punching, the automobile body sheet metal parts will be deformed due to the pressure of the punch column, thereby reducing the quality of the automobile body sheet metal parts.

[0004] The existing tooling for punching holes in the outer shell of the automobile suspension arm bushing kit has a relatively simple internal and external structure. It cannot be well positioned, clamped, or prevented from deformation during use, and cannot meet people's usage needs. In view of the above situation, technical innovation is carried out on the basis of the existing heat sink welding tooling. Utility Model Content
