Description

Composite mold for blanking, punching, flanging and forming

technical field

The invention relates to a mold, in particular to a blanking, punching, flanging and forming composite mold. the

Background technique

In the production process, if the workpiece to be produced is to be formed by inner hole flanging and deep drawing, then it is necessary to use blanking, punching, flanging and forming composite molds, and blanking, punching, and flanging forming composite molds need to be drawn and deformed according to the needs of the workpiece The size of the degree determines the sequence of blanking, punching, flanging, and forming. For some workpieces with small tensile deformation, the flanging is generally formed after blanking and punching. However, although the flanging and forming height of some workpieces are not large, the curved edge of the workpiece tends to become irregular after shallow drawing. Qi, then the step of flanging cannot be realized normally, and manual operation is required, which not only has low labor efficiency, but also is prone to accidents. Therefore, in this case, measures should be taken to design special molds to handle this type of workpiece. the
