Abstract

The invention provides a machining method for a condensation pipe of a condenser. The problems that an existing condensation pipe machining method is complicated and production cost is high can be solved. The method includes the following steps that first, a head is made, and then a stretcher is used for conducting multi-pass stretching on a copper alloy pipe blank; second, straightening is performed, and then a copper alloy pipe is subjected to saw cutting and deburring according to the required length; third, oil stains on the surface of the copper alloy pipe are scrubbed away, and copper cuttings inside the copper alloy pipe are blown down; fourth, annealing is conducted; fifth, internal threads and external fins of the copper alloy pipe are machined with a wire rolling mill and accordingly the condensation pipe can be prepared; sixth, straightening is performed again; seventh, total air tight testing is carried out, qualified products are put into an ultrasonic cleaning machine tobe cleaned and finally are aired or dried, and unqualified products are scraped; and eighth, finished product storage is conducted.

Description

technical field [0001] The invention relates to the field of processing parts of condensers, in particular to a method for processing condensation pipes of condensers. Background technique [0002] The condenser is a kind of heat exchanger, which can transfer the heat in the condensing tube to the air near the condensing tube in a very fast way. In order to improve the heat exchange efficiency of the condenser tube, the internal thread is usually processed on the inner surface of the condenser tube, and the outer fin is processed on the outer surface. However, the existing processing method of the condenser tube is relatively complicated and the production cost is high. Contents of the invention [0003] In view of the above problems, the present invention provides a method for processing the condenser tube, which can solve the problems that the existing condenser tube processing method is relatively complicated and the production cost is high. [0004] Its technical sche...
