电解加工制退杆沟槽的大长径比电极设计

摘要

为解决某火炮制退杆沟槽加工工艺性差、加工精度低的难题，对原有加工工艺和用于加工沟槽的紫铜电极进行分析，提出了一种新的电极结构，并采用ABAQUS有限元法和Matlab微分法对新结构进行静力分析。仿真结果表明：该方法可将制退流液孔面积加工误差由3.405 mm2减小至0.5 mm2以内，适用于制退杆沟槽的精细加工。%In order to solve the problem of poor processing manufacturability and low processing precision of a gun’s recoil rod groove, analyzing the old processing technology and the copper electrode used for machining grooves, proposes a new electrode structure, and use ABAQUS finite element method and Matlab differential analysis for the new structure, the simulation results show that this method can reduce the recoil discharge hole area machining error from 3.405 mm2 to 0.5 mm2 in order to fine processing of the recoil rod groove.
