Research on Wall Thickness Reduction Rate of Al6063 Tube Progressive Forming
Based on the orthogonal test method,the plastic forming of Al6063 aluminum alloy pipe fittings by a single point progressive forming machine for pipe fittings was quantitatively analyzed.Through the finite element software ABAQUS simulation,the influence of various process parameters on the maximum thinning rate of Al6063 pipe fittings after forming was explored,and the best combination of process parameters was found.The results show that the order of influence of the process parameters from the largest to the smallest is radial feed distance,tool head radius,axial feed distance and friction coefficient.With the pipe size of 60 mm radius and 1 mm wall thickness,the optimal combination of process parameters is tool head radius of 6 mm,radial feed distance of 0.5 mm,axial feed distance of 1.5 mm,and friction coefficient of 0.100.The optimal combination of process parameters will change slightly with the change of pipe size.
