Abstract

The invention discloses a multi-punching-head punching structure, which comprises an upper template and a lower template for fixing a punching workpiece, wherein the upper template is provided with a plurality of different punching head groups for punching the punching workpiece fixed by the lower template; each punching head group comprises more than one punching head; punching heads belonging to the same punching head group have the same free stroke; punching heads of different punching head groups have different free strokes; and each free stroke refers to the vertical distance between a start point where punching of a punching head blade is started and an end point where the punching head blade is contacted with the punching workpiece fixed by the lower template. The invention has the advantages that: the punching heads of different punching head groups have inconsistent contact time with the punching workpiece, so that load provided by the tonnage of punching equipment in which the structure is used is concentrated on one or more punching heads which are contacted with the punching workpiece at a certain moment instead of being dispersed on all punching heads, and relatively large punching load required by punching can be provided even by smaller tonnage.

Description

technical field [0001] The invention relates to a stamping die structure, and mainly relates to a multi-punch stamping structure. Background technique [0002] Stamping processing is a commonly used method of metal plastic processing. It mainly relies on the equipment to give the punch a certain impact force, so that the cutting edge of the punch contacts the stamping workpiece, causing corresponding plastic deformation, so as to achieve processing. Purpose. In the existing stamping process, when punching and deburring the horizontal surface of the stamped workpiece, generally multiple punches with the same cutting edge height are used for processing, so that the cutting edges of multiple punches are at the same time as the horizontal surface of the stamped workpiece. Contact, at this time, the stamping load provided by the tonnage of the stamping equipment is evenly distributed on each punch edge. When it is necessary to stamp thicker stamping workpieces, in order to prov...
