Welding process of 5G large die casting

Abstract

The invention provides a welding process of a 5G large die casting. An original integral product is separated into two parts of castings, and then the two parts of castings are welded into a whole, sothat the manufacturing precision of a single part of castings is high, the welding between the two parts of castings is stable and reliable, the manufacturing cost is reduced, and the manufacturing efficiency is improved. The welding process of the 5G large die casting comprises the two parts of castings formed through design and separation, wherein each part of castings is provided with a corresponding fin area; the opposite splicing ends of each part of castings are provided with laterally-protruding welding areas relative to the width direction in a reserved mode; downwards-protruding auxiliary welding parts are reserved on the lower surfaces of the two sides, used for forming the lower surface of a working cavity, of each laterally-protruding welding area at the same time; the opposite faces of the opposite splicing ends of the two parts of castings are spliced; welding connection is conducted on the opposite upper surfaces of splicing seams through friction stir welding; then theparts, protruding outwards in the width direction of the integral casting, of the laterally-protruding welding areas are cut off; and the integral casting structure is turned over.

Description

technical field [0001] The invention relates to the technical field of manufacturing large die castings, in particular to a welding process for 5G large die castings. Background technique [0002] With the rapid development of 5G, the application of 5G equipment is getting higher and higher. The equipment corresponding to the 5G base station is relatively large. Due to the large size of the existing 5G large-scale die-casting parts, it needs to use a die-casting machine of more than 4000t for die-casting manufacturing. , which makes the manufacturing cost high, and due to the large volume and area of ​​the die-casting machine, there are relatively many defects during its manufacturing, and it takes a lot of time to repair in the later stage, which makes the production cycle of a single die-casting part long and low in production efficiency. Contents of the invention [0003] In view of the above problems, the present invention provides a welding process for 5G large-scale ...
