In addition, most of the lining cores of the brake hose connectors for domestic vehicles are manufactured by a machining method at present, the production procedures are multiple, the material utilization rate is low, the manufacturing cost is high, the dimensional accuracy is unstable, and leakage or separation is easy to generate.
Disclosure of Invention
The invention aims to provide a leakproof V-shaped sealing surface integral lining core type brake hose metal joint and a production process thereof, which fundamentally solve the unsafe problem that the vehicular brake hose metal joint is easy to leak or separate when a hose assembly connecting system is manufactured.
In order to achieve the purpose, the invention adopts the following technical scheme:
a production process of a leakproof V-shaped sealing surface integral lining core type brake hose metal joint is characterized in that a lining core and a metal joint body are simultaneously processed by a cold heading method, and the lining core and the metal joint body are not required to be connected together by a riveting method or a welding method.
The method specifically comprises the following steps:
s1: cutting the metal cold heading steel according to the standard length of the joint;
s2: and transferring the cut steel to a cold heading station by using a mechanical gripper, and simultaneously cold heading the lining core and the metal joint body by using a cold heading process.
The metal cold heading steel material is No. 15 or No. 20 steel material.
The metal joint is characterized by comprising a metal joint body 1 and a lining core 2, wherein the metal joint body 1 and the lining core 2 are integrated and are manufactured by cold heading; a cavity is reserved in the metal joint body 1, one end of the cavity is completely opened, a lining core is arranged in the other end of the cavity, the longitudinal section of the opened end 11, which is in contact with the lining core 2, is V-shaped, and the included angle is 118-122 degrees.
The invention adopts the cold heading method to process the lining core and the metal joint body simultaneously, and does not need to connect the lining core and the metal joint body together by a riveting method or a welding method.
