冷挤压模具磨损优化设计
Optimum Design of Cold Extrusion Die Wear
摘要
Abstract
The cold extrusion three-dimensional geometric model and the finite element model of the flange nut were established by taking the flange nut's cold extrusion die as an example.By analyzing the core wear of the cold extrusion process,the four-factor three-level orthogonal experiment was designed based on the friction coefficient,initial hardness,punching speed,and the radius of the fillet entrance fillet.Through the Archard-wear model and theory,the orthogonal experiment of cold extrusion die wear in Deform-3D numerical simulation software was carried out.The optimal four-factor combination with the smallest core wear was obtained,the relationship between four factors and mold wear was studied,and the reason why the punching speed of punching rods becomes the biggest factor of core wear was analyzed.The results show that,through the orthogonal experiment and wear model can accurately calculate the core wear,predict the life of the core,improve the process design.关键词
