Spring clip progressive die with buffering piece

Abstract

The invention provides a spring clip progressive die with a buffering piece, belongs to the technical field of molds and aims at solving the technical problems that the die production efficiency of an existing spring clip is low and the like. The spring clip progressive die with the buffering piece comprises an upper die seat, a lower bottom plate and a plurality of guide columns which are arranged on the upper die seat; the lower bottom plate is sequentially provided with a corner cutting-off insert, a first convex-point insert, a punching insert, a first stretching insert, a second convex-point insert, a second stretching insert, a first waste material insert, a second waste material insert, a bent forming insert and a cracking insert in sequence; a first elastic pressing plate, a molding convex block and a second elastic pressing plate are arranged on the upper die seat in sequence; the first elastic pressing plate is matched with the corner cutting-off insert, the first convex-point insert, the punching insert, the first stretching insert, the second convex-point insert, the second stretching insert, the first waste material insert and the second waste material insert; the molding convex block is matched with the bent forming insert; the second elastic pressing plate is matched with the cracking insert. The spring clip progressive die has the advantages of high efficiency, stable quality and the like.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to a spring clip progressive die with buffer parts. Background technique [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 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 installation is more strenuous and the yield is lower. [0003] For this reason, the applicant designs this progressive die in order to improve the stability of the spring clip, the produ...

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
