A Study on the Formability Factors of Axisymmetric Multi-Stage Deep Drawing Processes

축대칭 다단계 딥드로잉 공정의 성형인자에 대한 연구

A good drawability of material itself is required. To improve the formability in deep drawing process. Besides that bending resistance should be reduced by increasing die round appropriately, drawing load should be minimized by improving the lubricant condition between die and material, and breaking load should be increased by selecting a pertinent punch round and by augmenting the friction resistance in Punch. In this study, a multi-stage deep drawing process is analyzed using ABAQUS, the effects of formability factors. Such as die shoulder radius, punch-die clearance and friction coefficient are investigated.
