Spring clamp progressive die

Abstract

The invention provides a spring clamp progressive die, and belongs to the technical field of dies. The spring clamp progressive die solves the technical problems that an existing spring clamp is low in die production efficiency and the like. The 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. The lower bottom plate is sequentially provided with a corner cutting insert, a first convex point insert, a punching insert, a first stretching insert, a second convex point insert, a second stretching insert, a first scrap insert, a second scrap insert, a bending forming insert and a material cutting insert. The upper die base is sequentially provided with a first spring pressing plate, a forming lug and a second spring pressing plate, wherein the first spring pressing plate is matched with the corner cutting insert, the first convex point insert, the punching insert, the first stretching insert, the second convex point insert, the second stretching insert, the first scrap insert and the second scrap insert, the forming lug is matched with the bending forming insert, and the second spring pressing plate is matched with the material cutting insert. The spring clamp progressive die has the advantages of being high in efficiency, stable in quality.

Description

Technical field [0001] The invention belongs to the technical field of molds and relates to a spring clamp progressive mold. Background technique [0002] Sofas are commonly used fixtures. 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 passes The process, multiple molds are divided into multiple processes such as blanking, pre-stretching crowning, stretching and fixing and bending, which is time-consuming and labor-intensive, and the quality is unstable, often with large size deviations, bumps or insufficient bending When the situation occurs, the installation is more laborious and the yield is lower. [0003] Therefore, the applicant designed this progressive die in order to improve the stability, production efficiency and cost reduction of the...

[0002] The sofa is a commonly used fixture. 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 used in the production process of the sofa. Because the traditional spring clips require multiple molds Process, multiple molds are divided into multiple times to complete the blanking, pre-stretching top convex, stretching convex and bending forming processes, which is time-consuming and labor-intensive, 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
