One-time forming die for stamping button surface piece

Abstract

The invention discloses a one-step forming die for stamping a button surface piece, which comprises an upper die, a lower die, a lower die, a lower die, a punching sleeve and a punching insert pin, the upper die is provided with a punching sleeve and a punching insert pin, and the punching sleeve is coaxially sleeved on the punching insert pin; a first insert and a second insert are sequentially arranged on the lower die in the punching direction; and the limiting assembly can enable the punching insert pin to move or be static relative to the blanking sleeve. The punching sleeve and the punching insert pin which are coaxially designed can be used for manufacturing a finished product through single-time mold closing, so that the machining time is saved, the first insert and the second insert are sequentially arranged in the material punching direction, the utilization rate of the mold machining area is increased, more forming holes can be designed in the unit area, the machining number of products can be increased, and the machining efficiency is improved. Compared with the prior art, more products can be processed within shorter time.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a one-step forming die for stamping button face parts. Background technique [0002] The longitudinal section of the button face piece is in the shape of "凵", which is used to cover the end face of the button, and is made by punching a sheet with a punching die. In the prior art, the method of using a stamping die to process includes the first step of punching out the sheet body and making a circular embryonic body sheet, and the second part is bending and forming and making a finished workpiece in the shape of "凵". The product can only be obtained by opening two acupoints on the mold and closing the mold twice, which has the following shortcomings: (1) Two inserts need to be arranged corresponding to the two acupoints, one for punching out a circular blank sheet, the other One is used for bending and forming a finished workpiece in the shape of "凵", which requires a large...

AI Technical Summary

Problems solved by technology

In the prior art, the method of stamping die processing includes the first step of punching the sheet and making a circular embryo sheet, and the second step of bending and forming the finished workpiece in the shape of "凵". The product can only be produced by opening two acupuncture points on the mold and closing the mold twice, which has the following disadvantages: (1) two inserts need to be arranged corresponding to the two acupuncture points, one is used for punching out the circular embryo body sheet, and the other One is used for bending and forming to produce a finished workpiece in the shape of "凵", which requires a large processing area per unit area, which limits the number of products obtained when a set of molds completes a single processing step; (2) a single The processing step needs to be closed twice. In the circular production line, it causes a waste of time and limits the production efficiency. The composite mold is used to complete punching, shearing and forming at one time, but the composite mold can only be arranged as a single independent mold due to structural limitations. The punch has the following disadvantages: there is only one processing station on the mold
