Progressive die punching process cutter joint burr processing device and process

Abstract

The invention discloses a progressive die punching process cutter joint burr processing device and process. The device comprises an upper die base and a lower die base used in cooperation with the upper die base. The lower die base is provided with a concave die plate. A V shape forming punch is arranged on one side of the concave die plate, and a shearing punch is arranged on the other side of the concave die plate. The cutter joint zone of the V shape forming punch is a bevel, and the bottom of the bevel is a circular bead. The burr processing device is simple in structure and convenient to use; the cutter joint of a product is subjected to V shape forming treatment, the same position is subjected to shearing in the next procedure, and thus the problem of product burrs caused by punching in a die can be completely avoided; and the problem that cutter joint burrs cannot be processed in the die finally is solved, the subsequent deburring procedures such as vibration grinding are omitted, cost is reduced, and the quality requirement of the product is met.

Description

technical field [0001] The invention relates to a burr treatment device and a process, in particular to a burr treatment device and a process for a progressive die stamping process where a knife is connected. Background technique [0002] In ordinary punching, burrs will be generated after the material is punched. Usually, when the product requires no burrs, the traditional method is to add a chamfering process to the circumference of the product, but the burrs at the final joint of the material area cannot be removed in the mold. Other processing can only be done afterwards: such as vibration grinding, which also has unstable factors, increases costs, and cannot fully meet customer needs. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a device and process for treating burrs at the cutting edge of the progressive die stamping process. [0004] The present invention is achieved through the following...
