Abstract
The technical questions in the structure design and forming process of extrusion die for piston bolt were analyzed, and the unreasonable place in original structure such as punch size, discharge way, quenching hardness and die centering way were optimized and improved in mould design. Practice shows that,the improved mould has more reasonable structure and solves at root a great deal of questions such as short punch life, difficult discharge and higher temperature of the mould. It increases product qualified ratio and reduces mould producing cost.关键词
