AI Technical Summary
The existing cold extrusion molding equipment for automotive shock absorber pistons has low processing efficiency, especially in the loading and unloading process, which takes a lot of time.
A cold extrusion device was designed, comprising a base, a forming mold, a moving carrier, a hydraulic press, and a cold pressing head. The moving carrier carries the piston block and moves it cyclically along the processing guide rail. The piston block is cold extruded and formed by combining the hydraulic press and the cold pressing head. The piston block is automatically captured and repositioned by the cooperation of the supporting cylinder and the lower support block, thus avoiding the loading and unloading process of traditional robotic arms.
It effectively improves the processing efficiency of piston blocks, shortens the processing time interval between adjacent piston blocks, improves the overall processing efficiency, and simplifies the replacement of the inner mold cylinder through mold combination design, reducing wear.
