Curled round one-time forming die

Abstract

The invention relates to a curled round one-time forming die, wherein, the lower surface of an upper template is fixed with an upper base plate, and the upper surface of a lower template is fixed with a lower base plate; lower inserts are intermittently fixed on left and right sides of the upper surface of the lower base plate, and a slide driving slope is arranged on the opposite wall surfaces of the two lower inserts; an elastic jacking block is arranged between the two lower inserts; an elastic jacking screw hole is integrally arranged in the lower template and the lower base plate, and the elastic jacking screw hole is internally equipped with elastic jacking screws; an elastic jacking block groove is arranged on the top end of the elastic jacking block, and a left half block and a right half block are arranged on the elastic jacking block; a left forming wall is arranged on the right corner of the left half block, and a right forming wall is arranged on the left corner of the right half block; a mandril is inserted in a circular hole; the left wall of the left half block is fixed with a left sliding block, and the right wall of the right half block is fixed with a right sliding block; and the left sliding block is equipped with a left sliding slope, and the right sliding block is equipped with a right sliding slope. The die of the invention can achieve curled round one-time forming, thus improving the yield and the quality of products.

Description

technical field [0001] The invention relates to a rolling forming mold used as a bushing, in particular to a rolling forming mold for one time. Background technique [0002] Ordinary plate rolling process needs to go through four steps of blanking, pre-bending, rolling and shaping (as shown in the figure below). Such a process requires a lot of equipment and labor, and due to the variety of processes, each process has a certain error, so the cumulative error of the product is relatively large, and the size of the final product is unstable. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a roll-forming die which can form rolls at one time, improve the output and quality of products, and reduce the input of equipment resources and human resources. [0004] According to the technical scheme provided by the present invention, the roll forming mold includes an upper template and a lower te...
