摘要
Abstract
In order to improve the life of die and reduce the cost of mould test,the forming process and design method of the die were studied by taking the core of sewing machine as an example.In order to solve the problem that traditional process face is always uneven,a new die structure is designed with finite set.According to the structure of the bobbin,two kinds of bobbin cold extrusion forming processes are put forward,and the processes are simulated using the finite element simulation software DEFORM-3D.We found that the extrusion forming scheme by 2 step simulation of the forming effect of the common is good.The forming load and the size of the punch wear volume were used as the evaluation index and the best combination of process parameters were obtained based on orthogonal test analysis and extreme difference analysis.The optimal combination of parameters was utilized to explore the influence of different friction factor on the forming load,the different punch initial hardness of convex on the die wear influence.The optimized crash injury factor nephogram,equivalent strain cloud and cloud folding angle were analyzed and the feasibility of the rear die was verified.The research provides a reference for the actual production of spindle parts and the production of similar parts.关键词
