Hardware product hemming stamping die

Abstract

The invention relates to a hardware product hemming stamping die. The hardware product hemming stamping die comprises a workbench, two attaching devices, a limiting device, an ejection device, a U-shaped frame, a stamping device and four clamping devices, wherein the attaching devices are symmetrically arranged on the upper end surface of the workbench in a bilateral symmetry mode, the two clamping devices are connected by the limiting device, the ejection device is arranged behind the lower end of the workbench, the clamping devices are symmetrically arranged on the left side and the right side of the workbench, the U-shaped frame is installed at the front end of the right side of the workbench, and the stamping device is installed on the lower end surface of the U-shaped frame. The hardware product hemming stamping die can solve the problems that when an existing iron sheet is punched, the iron sheet can be directly placed into a clamping groove, and a fixing device is not arranged in the clamping groove, and during stamping, wrinkles can be generated between the iron sheets in the punching process, the iron sheet can also shake, stamping deviation is avoided, and hemming is noteasy to form, and meanwhile, an existing external rigid clamping device and an iron sheet contact part are easy to deform.

Description

technical field [0001] The invention relates to the field of crimping machinery, in particular to a stamping die for crimping of hardware products. Background technique [0002] Hemming refers to the process of curling the edge of the workpiece in order to increase the rigidity and strength of the edge of the workpiece. Hemming is the most widely used in the production and processing of hardware products. Among them, the hemming of pipes or tanks is the most common, and tin cans are the most popular among them. It is the most common and widely used representative. Nowadays, when crimping and stamping tin cans, crimping machines are usually used for crimping and stamping. The crimping machine has the advantages of simple operation, low cost, and high efficiency. However, in crimping and stamping The following problems will arise during the process: [0003] 1. When crimping the tin cans, usually put the tin cans directly into the card slot. There is no fixing device inside t...

AI Technical Summary

Problems solved by technology

[0006] The invention can solve the problem that when the existing tin cans are crimped and stamped, usually the tin cans are directly put into the card slot, and there is no fixing device inside the slot. During the stamping process, wrinkles will be generated in the middle of the tin cans, which will greatly affect the appearance of the tin cans. Affected, the tin can will also shake, causing the stamping to deviate. When the punch directly stamps the upper end of the tin can, it will not be easy to form curling. There is a certain distance, which will cause damage to the hands of the picker. At the same time, the existing external rigid clamping device and the contact part of the tin can are prone to deformation and other problems.
