Novel inner hexagonal screw plug blank forming process

Abstract

The invention discloses a novel inner hexagonal screw plug blank forming process. The novel inner hexagonal screw plug blank forming process comprises the steps of raw material preparation, raw material detection, qualified raw material feeding, material annealing, processing and the like, after a material with the outer diameter larger than the outer diameter of a product is feed and subjected toannealing and heat preservation, the Rockwell hardness of material is lower than zero degree, and subsequent extrusion and drawing are carried out to obtain a blank. On the basis of the process in the prior art, the technological process with a better effect is obtained through multiple tests, the adverse defects of independent use of various processes on the product can be effectively reduced, and the high-performance blank is provided for a user; and a raw material finished product with high strength and excellent performance can be produced, and the produced raw material blank has good high-pressure resistance and high-temperature resistance properties.

Description

technical field [0001] The invention relates to the technical field of forming technology for hexagonal socket plug blanks, in particular to a novel forming process for blanks of internal hexagonal screw plugs. Background technique [0002] Screw plugs are parts that are connected by threads to prevent liquid leakage. The threads can be standard threads or pipe threads. Hexagon socket plugs, 60° conical pipe thread socket socket socket socket socket sockets, external hexagon socket socket sockets, pipe thread external hexagon socket sockets, cylindrical head sockets, high pressure socket sockets and water plug washers, among others, the application of socket socket socket socket sockets The most widely, hexagon socket plug processing needs to be processed into hexagon socket plug blanks first, and the existing processing blanks include cold heading process, hot forging process and cutting process; the cold heading process is to anneal and cool the material smaller than the o...

Problems solved by technology

The advantages of flexible operation and high precision of the inner hexagon; however, due to the punching process of the cutting process, cutting residues will be generated after processing, so it is not suitable for surface treatment with pickling, and during the punching process, the processing of the inner hexagon The reserved hole will be deeper than the depth of the inner hexagon, and the surface of the inner hexagon processed by cutting is not smooth, and the surrounding strength of the inner hexagon is weak, so it is not suitable for fastening with a large torque of the wrench tool; because the existing technology is used to make the inner hexagon plug The blank technology has its own advantages and disadvantages, which will make it difficult for the products processed by the existing technology to meet the expected performance and requirements, and because of the shortcomings of the existing technology used to make the hexagon socket plug blank, it will also cause various problems to the product. Unfavorable defects, so an improved processing technology is needed to solve the above-mentioned problems in the existing hexagon socket plug blank forming process
