Structure of pipe joint and pipe joint pipe processing method in piping of car air conditioner

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe for pressurizing a liquid body or a gas body in an air conditioner installed in a vehicle including an automobile, It is an object of the present invention to provide a pipe joint forming method for forming an automotive air conditioner piping by having a pipe joint forming structure by a unique flare method so as not to cause any problems according to the conventional silver brazing method, By improving the fitting method to the piping of the built-in air conditioner, even if the vibration stress of the car reaches the pipe joint part, the pipe joint part is not damaged, so that the pipe can be easily replaced And the piping operation of the air conditioner is quickly facilitated. The air conditioner according to the present invention, Pipe connection structure and pipe machining method Pipe cutting, deburring and finishing by using a corking machine and a roller burnishing machine, finishing by trimming and bending, and rinsing to determine the end of the pipe. A groove to be fitted is formed to form a swivel nut coupling structure or a flange coupling structure which can be assembled and disassembled. According to the pipe manufacturing method according to the present invention, when the pipe joint forming structure is applied to an automobile air conditioner pipe, the piping operation is quick and the pipe joint part is not vulnerable.
