Abstract
The invention relates to an exhaust pipe used for an air conditioning compressor, and the exhaust pipe comprises a copper pipe. The invention is characterized in that a connecting end of the copper pipe is tightly sleeved with a hoop, and the connecting end is fixed with the copper pipe by welding. A manufacturing method of the exhaust pipe used for an air conditioning compressor of the invention is characterized in that the manufacturing method comprises the following steps: the connecting end of the copper pipe is inserted into a columnar port of the hoop according to the required depth by a pressing machine; copper base solder is arranged on an annular joint point between the copper pipe and the hoop, and the copper base solder melts in a brazing furnace and permeates and fills a clearances on the annular joint point to realize the welding between the copper pipe and the hoop. An installation method of the exhaust pipe used for an air conditioning compressor of the invention is characterized in that the hoop of the invention is welded on a casing body of the air conditioning compressor in a resistance welding mode. The invention cancels the use of traditional high silver solder; the cost of an air conditioning is reduced; the competitive strength of products is strengthened; the pollution to the environment is reduced; the operating environment of operators is improved.
Description
Technical field:
The present invention is a kind of exhaust pipe for air-conditioned compressor and preparation method thereof and assembly method, belongs to the renovation technique of exhaust pipe for air-conditioned compressor and preparation method thereof and assembly method.
Background technique:
The air condition compressor outlet pipe generally adopts copper pipe at present, and it is by the upper shell welding of high silver solder gas brazing or high-frequency induction brazing and compressor.Because the price of silver is constantly soaring in recent years, cause the price continuous rise of high silver solder, compressor manufacturer and downstream air conditioning system maker all face huge cost pressure.
Summary of the invention:
The objective of the invention is to consider the problems referred to above and provide the high silver solder of a kind of cancellation to use, directly reduce the exhaust pipe for air-conditioned compressor of air condition compressor cost of production.
Another object of the present invention is to provide a kind of simple to operate, the exhaust pipe for air-conditioned compressor making method and the assembly method that reduce cost.
Technological scheme of the present invention is: exhaust pipe for air-conditioned compressor, comprise copper pipe, and wherein the connecting end of copper pipe tightens and is with iron hoop, and is solidly installed by welding.
The upper end of above-mentioned iron hoop is the tubing string shape that internal diameter matches with the connecting end external diameter of copper pipe, and it is horn-like that the lower end is.
The making method of exhaust pipe for air-conditioned compressor of the present invention, it comprises the steps:
1) by press machine with the connecting end of copper pipe as requested the degree of depth insert in the column port of iron hoop.
2) the copper parent metal is placed on ring-type seam crossing between copper pipe and the iron hoop, scolder melts and permeates the gap of filling up the ring-type seam crossing in soldering oven, to realize the welding between copper pipe and the iron hoop.
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, closely contact;
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, make realize between outlet pipe and the compressor housing firmly, reliable, leak free connection.
Exhaust pipe for air-conditioned compressor of the present invention is with iron hoop owing to adopt the connecting end of copper pipe to tighten, and the structure and the making method that are solidly installed by welding, and the present invention is welded on making method on the compressor housing with the outlet pipe iron hoop by the resistance welding mode, it has cancelled the use of traditional high silver solder, 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.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that outlet pipe of the present invention is welded on the structural representation on the compressor housing.
