Above-mentioned iron hoop one end is the tubing string shape, and it is horn-like that the other end is, and the butt end of copper pipe and iron pipe is pressed in the iron hoop pipe cylindrical end.
The making method of exhaust pipe for air-conditioned compressor of the present invention is characterized in that comprising the steps:
1) by press machine with copper pipe and iron pipe as requested the degree of depth be pressed in the tubing string shape port of iron hoop.
2) the copper parent metal is placed on ring-type seam crossing between copper pipe, iron pipe and the iron hoop, scolder melts and permeates the gap of the ring-type seam crossing that fills up between copper pipe, iron pipe and the iron hoop in soldering oven, to realize the welding between copper pipe, iron pipe and the iron hoop.
Compressor of the present invention is characterized in that with the assembly method of outlet pipe the iron hoop of above-mentioned outlet pipe is welded on the housing of compressor by the resistance welding mode, and it comprises the steps:
1) in the male cone (strobilus masculinus) of iron hoop horn throat and the set mounting hole of compressor housing, exerts pressure on the lateral edges, both are closely contacted;
2) in the male cone (strobilus masculinus) of iron hoop horn throat and the set mounting hole of compressor housing, pass to big electric current between the lateral edges, melt metal between two weldments by resistance heat;
3) outage back molten metal solidifies rapidly under the effect of pressure and realizes welding, makes between outlet pipe and the compressor housing and realizes firm, reliable, the leak free connection.
Exhaust pipe for air-conditioned compressor of the present invention is owing to adopt copper pipe to dock with iron pipe, structure and making method that iron hoop is sleeved on copper pipe and iron pipe joint and is solidly installed by welding, and the outlet pipe iron hoop is welded on making method on the upper shell of compressor by the resistance welding mode, it has not only cancelled the use of traditional high silver solder, and reduced copper pipe material use amount, comprehensively reduce the cost of air-conditioning, strengthened product competitive ability.In addition, the present invention has reduced the pollution to environment owing to replaced gas brazing or the high-frequency induction brazing technology of using high silver solder with resistance-welding process, has improved the operating environment of operator.
