Novel structure for inclined punching of multiple hole positions in small space and punching method of novel structure

Abstract

The invention relates to a novel structure for inclined punching of multiple hole positions in a small space. The novel structure comprises an upper die and a lower die which can be opened and closedrelatively, wherein the lower part of the upper die is provided with a workpiece accommodating cavity, a plurality of side punching heads are arranged in the workpiece accommodating cavity, and the lower die is provided with a side punching concave die for supporting a workpiece; the multiple side punching heads capable of conducting up and down side punching relative to the side punching concavedie, drive punching head bases, discharge plate inserts and cushion blocks are arranged in the workpiece accommodating cavity; the ends with punching heads of the side punching heads are sleeved withthe drive punching head bases; and the cushion blocks abut against the other ends of the side punching heads and correspond to the drive punching head bases. The novel structure for inclined punchingof the multiple hole positions in the small space can carry out punching operation on inclined surfaces in a part in multiple directions uniformly, and can also realize rapid die release.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to the field of processing of metal parts, and in particular to a novel structure of small-space porous position oblique punching. Background technique [0002] In the prior art, for example, the patent name is: punching die (patent application number: CN201720479966.7), which discloses a punching die, which includes a lower die base, a die, a guide plate, an impact block and a punch There is a hole on the lower mold base; the die is installed and limited on the lower die base, the die is provided with a blank placement position for positioning the blank, and the die is provided with a guide edge channel The guide plate is installed and limited on the lower mold base, and is located on the upper side of the die, and the guide plate is provided with a punch guide channel; the punch is accommodated in the punch In the guide channel, and the punch cooperates with the die to shear ...

AI Technical Summary

Problems solved by technology

For complex structures, it is not enough to increase the space utilization of spring stripping components

Moreover, it is not possible to uniformly punch holes in multiple directions

[0004] However, in the prior art, the operation of punching a plurality of positions on the same plane can be performed simultaneously on a plane workpiece.
