电阻点焊过程中压紧力的数值模拟及实验分析
Numerical simulation and experimental analysis of pressing force during resistance spot welding
摘要
Abstract
Resistance spot welding is an important process of connecting the projectile with the reduction vane.The size of the welding pressure during the spot welding directly affects the quality of the welding spot,thus affecting the parameters of the projectile.Numerical simulation was made on the difference of the pressing force between the projectile and the rotary vane.The deformation under different pressing force and the maximum internal stress on the workpiece were analyzed.The optimal compressive force range were obtained.Aiming at the machining process of the projectile and the rotary vane,a special NC spot welding machine was developed.The results show that when the pressure is 300 N,the radial deformation is 0.28 mm,which exceeds the requirement of welding joint quality in the welding process.Based on the finite element simulation and experimental results,the optimal pressing force is 250 N.关键词
