Method for replacing dies of high-speed punching machine

Abstract

The invention discloses a method for replacing dies of a high-speed punching machine. The method for replacing the dies of the high-speed punching machine comprises the following steps that A, pressing plates used for fixing the dies are dismounted; B, a scram button is pressed; C, the dies to be dismounted are made to retreat from a workbench slowly; D, the dies to be dismounted are hoisted out through a crane; E, the dies to be dismounted are ground and polished by means of a grinding machine and coated with anti-rust oil; F, die mounting positions are aligned; G, the scram button is pressed; H, the dies to be mounted are gently placed on a die mounting sliding plate through hoisting by means of the crane; I, the dies to be mounted are slowly pushed into guide rail grooves of the workbench; J, the dies to be mounted are adjusted to be aligned to a feeding machine; and K, the die mounting height of a punching main unit is adjusted till a qualified product is punched. Compared with the prior art, the method for replacing the dies of the high-speed punching machine has the beneficial effects that the service life of the dies is prolonged, the punching quality of the product is guaranteed, and requirements of high-end customers are met.

Description

technical field [0001] The invention belongs to the field of stamping manufacturing, is applicable to the replacement of molds for large-scale products, and relates to a method for replacing molds of high-speed punching machines. Background technique [0002] In the existing technology, the technical content of the mold is very high, and there are many various parts. If the maintenance and maintenance of various parts are not paid attention to in the process of use, damage and corrosion are very easy to occur, resulting in tens of thousands or even millions of yuan. Therefore, special attention should be paid to the maintenance and maintenance of the mold during use to ensure the long-term use quality of the mold. However, if the disassembly of large molds is not properly installed, it will affect the processing accuracy of punching pieces, resulting in the scrapping of finished products and increasing management costs. . Contents of the invention [0003] The problem to ...
