Turn-cutting die

Abstract

The invention relates to a turn-cutting die. The turn-cutting die comprises an upper die and a lower die. The lower die comprises a turn-cutting male die comprising a guide block, a horizontal turn-cutting cutter and a horizontal turn-cutting sliding block. A lower template is provided a male die front driving block, a male die rear driving block, a male die left driving block and a male die right driving block in the front, rear, left and right direction positions of the turn-cutting male die, and the inner side faces of the male die front driving block, the male die rear driving block, the male die left driving block and the male die right driving block are matched with the outer side faces of the horizontal turn-cutting sliding block in a guide mode correspondingly. According to the turn-cutting die, the turn-cutting male die is guide by guide rails of male die driving blocks around the turn-cutting male die, thus downward stamping motion of the lower template is converted into horizontal shearing motion of the horizontal turn-cutting cutter of the turn-cutting male die, then dislocation turn-cutting is conducted on the side wall of a pre-machined workpiece in the four horizontal directions, the cut-off face of the barrel workpiece cut by the turn-cutting die is flat, product quality is ensured, and product production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cold stamping dies, in particular to a rotary cutting die. Background technique [0002] The rotary cutting die is used for the trimming process of pipe parts. For stretched metal pipe products, trimming is often involved. In the traditional trimming process, the pre-processed punching parts are rotated in the axial direction. The trimming knife edge slides close to the inner wall of the stamped part for shearing. In this trimming process, there is no transition between the knife edge and the inner wall of the punched part, and the impact force of the blade against the inner wall of the punched part is large, resulting in arc chamfering on the cut surface of the inner wall of the manufactured product. At this time, it is often necessary to perform secondary processing such as grinding on the cut surface to make the end surface smooth and meet the product processing requirements. It can be seen that the...

AI Technical Summary

Problems solved by technology

It can be seen that the trimming process of the drive reduces the production efficiency of the product, and for products with high precision requirements, it often fails to meet the requirements

And when the die is punched into a shaped product, the punching accuracy is not good, and it is not easy to debug, which affects the production efficiency
