An Improved Spring Clip Progressive Die

Abstract

The invention provides an improved spring clamp progressive die, belongs to the technical field of dies, and solves technical problems of low production efficiency and the like of an existing spring clamp die. The improved spring clamp progressive die comprises an upper die base, a lower bottom plate and a plurality of guide columns arranged on the upper die base, wherein a corner cutoff insert block, a first convex point insert block, a punching insert block, a first stretching insert block, a second convex point insert block, a second stretching insert block, a first waste insert block, a second waste insert block, a bend forming insert block and a fracture insert block are arranged on the lower bottom plate in sequence; a first spring pressure plate, a forming bulge and a second spring pressure plate are arranged on the upper die base in sequence; the first spring pressure plate is matched with the corner cutoff insert block, the first convex point insert block, the punching insert block, the first stretching insert block, the second convex point insert block, the second stretching insert block, the first waste insert block and the second waste insert block; the forming bulge is matched with the bend forming insert block; the second spring pressure plate is matched with the fracture insert block. The improved spring clamp progressive die has the advantages of high efficiency, stable quality and the like.

Description

[0001] The present invention is an application date: 2013-10-21; patent number: 2013104968905; patent name: a divisional application of the invention patent of a spring clip progressive die. technical field [0002] The invention belongs to the technical field of moulds, and relates to an improved spring clip progressive die. Background technique [0003] The sofa is a commonly used furniture. The spring clips are respectively fixed to the two ends of the spring, and then the spring clips are fixed on the bracket of the sofa. A large number of spring clips are needed in the production process of the sofa. Because the traditional spring clip preparation mold requires multiple In the process, multiple molds are divided into multiple times for blanking, pre-stretching top convex, stretching convex and bending forming, etc., which is time-consuming and laborious, and the quality is unstable, often with large dimensional deviations, bumps or insufficient bending. And so on, the i...

[0003] The sofa is a commonly used furniture. The spring clips are respectively fixed to the two ends of the spring, and then the spring clips are fixed on the bracket of the sofa. A large number of spring clips are needed in the production process of the sofa. Because the traditional spring clip preparation mold requires multiple In the process, multiple molds are divided into multiple times for blanking, pre-stretching top convex, stretching convex and bending forming, etc., which is time-consuming and laborious, and the quality is unstable, often with large dimensional deviations, bumps or insufficient bending. And so on, so that the installation is more laborious, and the yield is low
