Machining method for heat conducting pipe

Abstract

The invention discloses a machining method for a heat conducting pipe. The method comprises the following steps of 1, conducting fin forming, wherein a cut plate forms fins through a fin forming machine or fin forming is directly performed on the plate and then splitting cutting is conducted, and the fins can be formed on the upper surface and the lower surface of the plate or on one surface of the plate; 2, conducting pipe forming, wherein forming is conducted on the finished plate through a pipe forming machine so that a round pipe with a seam can be formed; 3, conducting welding, wherein after the round pipe is formed through the pipe forming machine, welding is conducted on the seam of the round pipe; 4, processing a welding joint, wherein the unevenly welded portion of the seam of the pipe is ground and polished through a welding joint processing machine; 5, conducting annealing. By the adoption of the machining method for the heat conducting pipe, the heat conducting pipe is formed in a one-off mode from a plate band, and the machining process is shortened; because the technology that the fins are rolled on the plate band and then welding is conducted is adopted, destructive machining is not needed after welding, and the phenomenon that the weld joint may be damaged after rolling in the prior art is avoided.

Description

technical field [0001] The invention relates to a processing method of a pipe material, in particular to a processing method of a heat transfer pipe. Background technique [0002] In the prior art, the production process of high-efficiency heat exchange tubes is: [0003] First of all, the main pipe (pipe blank) needs to be produced. There are two common production methods for the main pipe: seamless production method and welded seam production method. Among them, the seamless production method mainly includes continuous casting and rolling method, extrusion method and drawing method. etc. The overall quality of the mother pipe produced by this method is good, but it is prone to large eccentricity, local defects that are not easy to detect, and high production costs; while the mother pipe produced by the welding method can basically overcome all the shortcomings of the seamless production method, The difficulty lies in the welding process. However, according to the develop...

AI Technical Summary

Problems solved by technology

The disadvantage is that the rolling process is complicated, the mother tube is manufactured first and then the fins are rolled, the production process is too long, and the production cost is high

Especially for the parent pipe produced by the welding production method, the rolling of the rolling mill is likely to damage the weld seam during the subsequent fin rolling process, thereby causing leakage risks to the heat exchanger, etc.
