Hydraulic Cylinder Cold Pulling Processing and Mechanics Analysis

Abstract:

This paper describes a method about hydraulic cylinder cold pulling processing. Take seamless steel tubes as raw materials, they are acidified and phosphates before the cold pulling to guarantee that mold and pipe have a good lubrication and have a high temperature stability during the cold pulling processing, thus the cold pulling process can be stable . When the seamless steel tubes are brought into the drawing processing, a process provides with a Hydraulic pulling machine, matches special cold pulling die, then they occur plastic deformation uniformly and satisfy the dimension requirements ,whose accuracy can reach IT7~IT8 and the surface roughness is Ra0.4 ~ 0.6. At the same time, it causes producing cold hardening, which makes the material strengthened. Compared with the traditional processing methods, drawing processing can remarkably improve the production efficiency, ensure product quality and improve the qualification rate of finished products.
