Study on Multi-Step Spinning Process for Disk-Like Part with Thickened Rim

Abstract:

This paper studies the process of a five-step spinning to thicken the edge of the disc-like part. By using finite element simulation and experiment, the sectional shape and flow-line distribution of the rim were studied. The results showed that the flow lines of the cross-section of the formed part are distributed along the shape of the part. The disc-like part with thickened rim can be well formed by a multi-step spinning process. A large bottom radian of roller groove can lead a folding in the first step and a reduced r can overcome the folding. An over-small angle αin step 2 will lead a pit defect, it can be solved by increasing the angle.
