Study On The Z Type Contact Turn-up Process Based On The Finite Element Simulation Of The Impact On The Shape Accuracy

With the launch of 4G network, People's demand for high-speed information transfer is higher and higher which further promote the development of high-speed connector. The speed of development for high-speed connector is dominated at a large extent by stamping technology, So the high frequency characteristics are not only the factor when we begin the design of high-speed connector, but also we still need think about the capability of factory's model design and manufacture.The traditional stamping process is based on trial and error method to design the stamping die. Due to the larger differences of the different structure of forming parts and material parameters of strip, we need continue to modify the model's design, then we can meet designer's request. That cause the long lead time to design the die and high improvement cost. To shorten the period of model design, reduce the cost of model has become the urgent problems to be solved for the major manufacturers.This paper will use the pin of Z high speed connector as the object of study, calculate the material reserve amount of using for flanging blanking according to math method, after setting up the 3D model of stamping die by using Solidworks soft, then achieve computer simulation by using ABAQUS numerical simulation software, at last we need judge whether the analysis is stable by using the relationship of kinetic energy of internal energy which are the result of computer simulation.In the case of steady state analysis, and then design the orthogonal finite element test method to find the optimal parameters of the flanging process. Through the research on the influence of die material and related factors of the flanging size, the lubrication condition of the die system is selected. Punch the chamfering parameters and metal material of Young's modulus are experiment design factors, under the guidance of experimental design theory, 9 finite element analysis is carried out. After analysis and variance analysis of the data, the punch for the flanging chamfer dimension terminal euphotic zone size is significant factor, the influence of die lubrication system is second, but the young's module of material has little effect. According to the experimental design of optimal parameters of mold design and mold trial, randomly selected sample of product size measurement and the measured data analysis, the finite element analysis results and the actual production is proved to be consistent. Thus established by ABAQUS numerical simulation software as the tool of flanging process method, achieve the optimal structure design of the flanging terminal.
