The reason for the deformation of U-shaped bending side wall in stamping process

Dongguan Precision Electronic Technology Co., Ltd. was established in January 2008 as a stamping processing enterprise. Products are widely used in precision connector terminals, relay shrapnel, micro motor shrapnel, IC lead frames, automotive terminals, precision shrapnel for household appliances, smart electronic components, medical terminals, and other consumer electronics industries. Passed ISO9001, ISO14001, TS16949 and other quality management system certifications, and all processes are strictly implemented in strict accordance with the requirements of the quality management system. When the U-shaped bending is processed by punching, the side wall rebounds relative to the bottom surface of the workpiece, and the side wall surface becomes uneven. It swells near the corner radius of the punch, and the center of the side wall bulges inward. The same phenomenon occurs with L-shaped bending. The reason for the deformation of the U-shaped bending side wall in precision stamping is that the gap between the punch and the die is too large, which causes the sheet metal and the punch to fail to fit during processing. And in the later stage of processing, springback occurs near the fillet of the punch and the upper part of the guillotine wall. What are the reasons for the deformation during processing?
