Abstract：
|
|
Because ZCuPb10Sn10 material is difficult to be deformed by cold extrusion forming,the author introduces the technologic process of the uniformly annealed and immersed in oil for 24 hours before extrusion,optimized thickness size and three dimension stress state in the paper.The result indicates that it breaks through the mistaken ideas that the organization can only be machined.Through the process,the casting organization is successfully extruded to change its performance.The technology enhances the prolongation ratio to 11% from 6%,saves 73.6% working time and 37.03% material.It improves loading capacity of whole bearing board and increases its service life.It has realized the goal of high qualities,high efficiency and material-saving.
