Flanging and stamping die for battery pack hanging lug

Abstract

According to the battery pack hanging lug flanging stamping die, reasonable machining position distribution is carried out on a plurality of bending plates of a workpiece, so that the stress of the workpiece is controllable during bending machining, the workpiece is prevented from being excessively deformed and generating deformation or cracks, and due to the fact that an arc lead angle is arranged at a groove opening of a middle groove of a third bending block, the machining precision is improved. The stress points of the cutter relieving block are dispersed in the flanging process, the problem that the part, where indentations are most likely to be left, of a workpiece is bent is solved, and therefore the quality of the machined workpiece is guaranteed.
