摘要

In response to the limitations of incremental forming technology in the manufacture of thin-walled parts with large forming angles, this paper presents the independent development of an incremental forming equipment capable of multi-angle processing. The equipment achieves independent control over the two rotational degrees of freedom of the forming tool through the coordinated operation of the motor and the electromagnetic clutch, thereby enabling multi-angle plastic forming of metal sheets. By employing a strategically designed “pyramid” incremental forming path, the equipment has successfully processed thin-walled parts with forming angles exceeding 90°.
