Problems solved by technology

[0003] However, this method has a large workload and low productivity
At the same time, in the welding process, the flux needs to be manually applied, and the welding efficiency is low, resulting in a low welding ring formation rate (less than 80%)

Abstract

The invention provides a manufacturing method for pressing powder into a welded ring. The method comprises the following steps of 1) sieving; 2) mixing powder; 3) performing thermal treatment and sieving; 4) pressing; 5) sintering. The method is less in processing steps, free from repeated wire drawing and annealing processes, capable of manufacturing the welded ring at a time, high in welding efficiency and production efficiency and high in welded ring yield.

Description

technical field [0001] The invention belongs to the technical field of manufacturing heterosexual self-wetting welding rings, and in particular relates to a method for manufacturing welding rings by pressing powder. Background technique [0002] The traditional welding ring manufacturing method usually includes the following steps: smelting→extrusion→wire drawing→annealing→ring making→post-processing, etc. Due to the large size of the extruded wire, it needs to be repeated many times (7-8 times) Only wire drawing and annealing can reach the specified welding ring size, and then the drawn and annealed wire is welded end to end through the ring making machine to obtain the final specification welding ring. [0003] However, this method has a large workload and low productivity. At the same time, during the welding process, flux needs to be applied manually, and the welding efficiency is low, resulting in a low welding ring forming rate (less than 80%).
