基于有限元的端子压接工装刀片刃口优化设计

摘要

线束端子压接工装刀片刃口易磨损，且对端子压接质量影响大。利用Deform软件，结合正交试验，参考材料断后伸长率下的最小弯曲半径，对工装关键部件———上、下钳口冲压端子的变形过程进行模拟仿真与优化设计，给出了端子压接刀片刃口倾角θ与宽高比ε的优化设计实例。经大量实验验证，该方法压接质量良好。%The blade edge of crimping tool is easily wear out , to make the terminal crimping quality decline .By use of Deform software ,combined with orthogonal experiment ,the deformation process of stamping terminal between the upper and lower jaws is simulated ,and the structure of the upper and lower jaws is optimized .The optimal design of blade edge angleθand aspect ratioεare carried out ,and the result is satisfied .
