Abstract

The invention discloses a totally chip-free spherical integrated hydraulic hose metal joint structure and a production process thereof. The structure is characterized in that a metal joint main body (1), a ball joint (3), a tee joint structure through hole (4), a hollow lining core tube (5), a lining core connecting tube (6) and a connecting rod (8) are of an integrated structure. The totally chip-free spherical integrated hydraulic hose metal joint structure can be massively produced at a high speed through a cold header according to the production process. The totally chip-free spherical integrated hydraulic hose metal joint structure and the production process thereof have the advantages of saving more than 60 percent of raw materials and saving a large amount of electric energy compared with the traditional method. According to the manufacturing method, a material-to-finished product ratio can reach 99 percent.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, and is suitable for the production process of mechanical cold heading processing of various metal joints related to flat spherical shapes of hydraulic hoses. its production process. Background technique [0002] like Figure 1-a , Figure 1-b , the ball-type hose metal joint is now widely used in automobiles, motorcycles, electric vehicles and other hydraulic brake pipeline system of the main connecting parts. [0003] The existing manufacturing structure of this oblate spherical joint metal part is that the whole part is made up of two parts, and one such as Figure 2-a The joint parts, after processing, will be as Figure 2-b or Figure 2-c The lining core parts are pressed in by the interference method, such as Figure 2-a In the hole of the joint parts, there are two ways to carry out the sealing process: one way is as Figure 3-a The interference sealing structure is form...
