Abstract：

Bearing bush is one of the important parts of gas engine,which is mainly bearing load between hole and movement. The part is required to have high precision and clearl and complete logo on the surface.The part is mainly manufactured by single\|process which results in complex process. According to the above reasons,and based on the analysis of forming process about bearing bush blanking，steel seal impressing and punching and bending, a set of punching case for multistage continuous mould instead of three stages was put forward，using which the producing requirements were met , the efficiency was improved and the cost was lowered with qualified precision.
