Abstract

The invention provides an integrated spherical hydraulic hose metal joint structure and a production process thereof. The integrated spherical hydraulic hose metal joint structure is characterized in that a metal connector body (1), a spherical connector (3), a tee structure through hole (4), a hollow liner core pipe (5), a liner core connection pipe (6) and a connection rod (8) are integrated. The integrated spherical hydraulic hose metal joint structure can be produced in a mass mode through the production process and a cold header, the integrated spherical hydraulic hose metal joint structure and the production process thereof can save more than 60% of raw materials and a large amount of electric energy compared with a traditional method, and the material finished product ratio through the manufacturing method can reach 99%.

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 oblate spherical shapes of hydraulic hoses, in particular to a spherical integral hydraulic hose metal joint structure and its production process . Background technique [0002] Such as 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 s...
