Method and device for repairing copper pipe component on heat exchanger of air conditioner

Abstract

The invention discloses a method and a device for renewing and repairing a copper pipe component on a heat exchanger of an air conditioner, and belongs to a producing device. The adopted scheme includes: first shearing a U-shaped pipe on the U-shaped pipe end of a heat exchanger copper pipe which needs repairing by using scissors, and then pushing an air gun from an inner hole of the copper pipe against a cutter rod and a cutter head which are approximately smaller than the inner hole of the copper pipe so as to split the copper pipe axially; drawing out the axially split parts of the copper pipe from the inner hole of the copper pipe by employing a drawing pipe core rod with a clamping slot, and drawing out the damaged copper pipe with a pair of nipper pliers; subsequently, inserting a new U-shaped pipe, employing a pipe expanding mechanism to expand the U-shaped pipe and from a cup-shaped mouth, and then finishing the repairing operation. Compared with the prior art, the method and the device for renewing and repairing the copper pipe component on the heat exchanger of the air conditioner solve the problem of renewing and repairing the damaged copper pipe component on the heat exchanger of the air conditioner, and have the characteristics of being convenient and quick to repair and free of causing any bad influence on the heat exchanger of the air conditioner and the like, thus being good in popularization and application value.

Description

technical field [0001] The invention belongs to the field of air conditioner manufacturing, and relates to a maintenance device for copper pipes of air conditioner heat exchangers, in particular to a method and a device for repairing copper pipe assemblies of air conditioner heat exchangers. Background technique [0002] Air-conditioning and refrigeration equipment manufacturing enterprises are very vulnerable to damage to the heat exchanger copper tubes during the air-conditioning manufacturing process. The traditional solution has always been scrapped because the copper tubes cannot be replaced, which has caused considerable losses to the company. Currently, there is no good solution. Contents of the invention [0003] The technical task of the present invention is to provide a method and device for renewing and repairing copper tube assemblies of air-conditioning heat exchangers in view of the deficiencies in the prior art above. [0004] The technical solution adopted...
