Double-pipe processing method and double-pipe processing machine

Abstract

The invention provides a double-pipe processing method. The double-pipe processing method is used for solving the problems that processing steps are tedious and finished product specifications are inconsistent when double pipes are combined in the prior art. The double-pipe processing method comprises the following steps of positioning two to-be-processed pipe fittings by using a clamp, stamping the two pipe fittings at least once, respectively forming first stopping convex parts on the peripheral surface of the two pipe fittings, respectively sleeving two through holes of a combination seat on the two pipe fittings, wherein the first end of the combination seat abut against the first stopping convex parts of the two pipe fittings, stamping the two pipe fittings at least once, respectively forming second stopping convex parts on the peripheral surface of the two pipe fittings, and enabling the second stopping convex parts of the two pipe fittings to abut against the second end of the combination seat, so that the first stopping convex parts and the second stopping convex parts of the two pipe fittings jointly clamp and position the combination seat.

Description

technical field [0001] The invention relates to a pipe fitting processing method and a pipe fitting processing machine, in particular to a double pipe processing method and a double pipe processing machine in which two pipe fittings are combined into a joint seat. Background technique [0002] Please refer to figure 1 As shown, it is a kind of existing vehicle air-conditioning pipe fitting 9, and this existing vehicle air-conditioning pipe fitting 9 is formed by combining two pipe fittings 91 and a joint seat 93 with each other. In the current industry, the following steps are often used to manufacture the existing vehicle air-conditioning pipe fittings 9: first, the two pipe fittings 91 to be processed are stamped at least once by means of a punching machine, so that the outer peripheral surfaces of the two pipe fittings 91 are respectively formed into a The stopper 92, the joint seat 93 is sleeved on the two pipes 91, so that one end of the joint seat 93 is pushed against...

AI Technical Summary

Problems solved by technology

Since the two pipe fittings 91 and the joint seat 93 are combined by welding, not only the procedure is cumbersome and complicated, but also a defective product may be caused due to the error of the worker's welding process, which leads to the failure of the existing vehicle air-conditioning pipe fitting 9 Cannot be used smoothly during assembly
