Cold Extrusion Process Analysis of "Seven-Speed Sleeve" and Forming Parameter Optimization

Abstract:

The scheme for cold extrusion process of Seven-speed sleeve is determined according to the experiences and analysis by DEFORM-3D software, the extrusion procedure has been numerical simulation analyzed; The part technology and parameters of die structure has been optimized by orthogonal test. The optimized process parameters are as following: friction factor is 0.10, blank height is 31.4mm, extrusion speed is 200mm/s; The optimized parameters of die structure are as following: 1st step convex fillet is 1.5mm, 1st step concave rounded is 2.0mm, 2nd step convex fillet is 2.0mm, 2nd step concave rounded is 1.0mm, 1st step die-entrance angle is 35°, 2nd step die-entrance angle is 60°.The qualified products are obtained using the optimized process parameters in the production practice.
