AI Technical Summary
The existing internal toothed metal tube torsion forming process carries the risk of fracture and excessive local deformation due to stress concentration, and the precision of the finished product is difficult to guarantee.
By separating the fixed torsion point and the moving torsion point, and by lengthening the distance between the two torsion points, the internal gear helix angle is obtained by superimposing the torsion, thereby reducing stress concentration and improving the accuracy of the finished product.
It effectively reduces shape accuracy errors and defect rates caused by stress concentration, and improves the finished size and shape accuracy of internal toothed aluminum tubes.
