Problems solved by technology

[0002] At present, when air-conditioning manufacturers produce heat exchangers, once the long "U"-shaped copper tubes (hairpin tubes) have defects such as leakage, linear scratches, cracks, and impurities, the entire heat exchanger will be scrapped, causing great harm to air-conditioning manufacturers. Economic loss, the air conditioner manufacturer will transfer this loss to the copper pipe manufacturer, which will also cause certain losses to the copper pipe manufacturer

Embodiment Construction

[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0033] The technical method for repairing copper tube defects of air-conditioning heat exchangers, firstly put the defective air-conditioning heat exchangers to be repaired into water, and detect the defective copper tubes by inflating and bubbling.

[0034] Use scissors or diagonal pliers to cut off the "U" part of the copper tube; in this way, the "U" copper tube (hairpin tube) is divided into two sections. It is also possible to cut out the copper skin first, and then cut off the "U"-shaped part of the copper pipe.

[0035] Then, one section of the copper pipe 4 is placed on the plastic pad of the working platform. Connect the air source to the air hammer, connect the air hammer to the connector 1; assemble the cutter bar 3 and the blade 2; as...

Abstract

The invention relates to a copper pipe defect repairing technical method, in particular to the defect repairing technical method for an air conditioner heat exchanger copper pipe and a special tool for implementing the method. The technical key point of the invention is that a cutter rod is arranged at the mouth of the copper pipe with defects and is beaten into the copper pipe by an air hammer and passes through the copper pipe; a copper skin of the copper pipe wall connected with the copper pipe is cut off; the gap jacked by the cutter rod is enlarged by joint pliers; part of the copper pipe of a fin exceeding the copper pipe is removed by the joint pliers and the copper skin is kept; a jig is pulled out and the copper pipe is passes through by a steel wire which also sleeves and backwards draws the copper skin; the copper pipe is contracted by the joint pliers and the copper skin is clamped and backwards pulled by a vice till the copper pipe and the copper skin are pulled out together. The invention has the advantages of simpleness and practicability, effectively maintaining the copper pipe with defects and obviously improving the yield of air conditioner heat exchanger.

Description

technical field [0001] The invention relates to a technical method for repairing copper tube defects, in particular to a technical method for repairing copper tube defects in air-conditioning heat exchangers, and also relates to a special device for realizing the method. Background technique [0002] At present, when air-conditioning manufacturers produce heat exchangers, once the long "U"-shaped copper tubes (hairpin tubes) have defects such as leakage, linear scratches, cracks, and impurities, the entire heat exchanger will be scrapped, causing great harm to air-conditioning manufacturers. Economic losses, air-conditioning manufacturers will transfer this loss to copper pipe manufacturers, which will also cause certain losses to copper pipe manufacturers. Contents of the invention [0003] The first aspect of the purpose of the present invention is to propose a technical method for repairing copper tube defects in air-conditioning heat exchangers. [0004] The technical...
