Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] A welding repair process for an extrusion die, comprising the following steps:

[0039] (1) First conduct failure analysis on the discarded mold to determine the type of failure, first observe from the macroscopic perspective, determine the failure location and failure area, then perform wire cutting on the failure location, observe and analyze its microstructure, and determine Invalid form.

[0040] (2) Choose different welding repair principles for different defects. For some very small wear of the cutting edge, partial re...

Abstract

The invention discloses a welding repairing process for an extrusion die. The welding repairing process comprises the following steps that firstly, failure analyzing is carried out on the abandoned die, linear cutting and observation analyzing are carried out on failure parts, and failure forms are determined; secondly, different welding repairing principles are selected for different defects; thirdly, appropriate welding methods are selected for detect forms of a working tape; fourthly, physical and chemical property analyzing is carried out on welded tissues; fifthly, machining and post-treating are carried out on welded work; and sixthly, die testing and spot actual extruding are carried out on the repaired die, the actual extruding situation of the die is explored, an extruding result is analyzed, and repairing is carried out again. According to the welding repairing process, an electric pulse low-temperature welding new technology is adopted for repairing, a solid element diffusion layer will be produced in a base surface layer, high-binding performance is shown, disengaging will not occur, the workpiece repairing efficiency is high, and after-treatment is convenient.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of repair and reconstruction of discarded molds, in particular to a welding repair process for extrusion dies. [0003] 【Background technique】 [0004] In recent years, the competition in the manufacturing industry in the world has become more and more fierce. The ability of enterprises to provide customers with personalized high-quality products with high efficiency and low consumption in the shortest possible time has become a key to the competitiveness of enterprises. sign. Through the mold remanufacturing technology, some aluminum profile tools and molds that have partially failed or are out of tolerance can be "recycled" and "old parts resurrected", which can save expensive H13 special hot-working mold steel, and actually make molds quickly and prolong the life of the mold. The service life of the mold is in line with the concept of green manufacturing, and welding repair is the most critical t...
