Abstract
The present invention relates to a kind of methods of cold-drawn air-conditioner compressor outer housing, include the following steps：1. choosing welded tube, welded tube is handled through cold-drawing technology；2. the welded tube after cold-drawn is carried out temper；3. taking out welded tube, welded tube surfaces externally and internally finish is controlled, controls length.A kind of method of cold-drawn air-conditioner compressor outer housing is provided, can make the shell processed that there is higher intensity, and can accurately controling shell wall thickness.
Description
Technical field
The present invention relates to a kind of methods of cold-drawn air-conditioner compressor outer housing.
Background technology
The quality of air-conditioner compressor outer housing, shell directly affects the quality of compressor, and conventional enclosure intensity is relatively low, after
Come this technical problem in order to overcome outer cover intensity low, the processing mode that cold-drawn is carried out to compressor case is used, because
Outer cover intensity after cold-drawn is greatly improved, but there is presently no a whole set of works that drawing is carried out to air-conditioner compressor outer housing
Skill.
Invention content
The technical problem to be solved by the present invention is to：It overcomes the deficiencies of the prior art and provide outside a kind of cold-drawn compressor of air conditioner
The method of shell.
The technical solution adopted by the present invention to solve the technical problems is：A kind of method of cold-drawn air-conditioner compressor outer housing,
Include the following steps：
1. choosing welded tube, welded tube is handled through cold-drawing technology；
2. the welded tube after cold-drawn is carried out temper；
3. taking out welded tube, welded tube surfaces externally and internally finish is controlled, controls length.
Further, the step 2. in, by welded tube place tempering furnace in, temperature control at 600-850 DEG C,
Tempering furnace is sealed 2-6 hours, is then opened tempering furnace and is cooled down automatically.
Further, the step 3. in, then the welded tube of taking-up carries out pickling → polishing inside and outside welded tube → rise endoporus
Control internal diameter → Vehicle Processing welded tube both ends control length → gas pressure test detection welded tube air-tightness → cleaning.
Further, the welded tube controls size through carrying out saw material after cold-drawn.
Further, step 1. in, welded tube is before cold-drawn, and welded tube is through pickling → phosphatization → saponification process.
The beneficial effects of the invention are as follows：A kind of method of cold-drawn air-conditioner compressor outer housing is provided, can make to process outer
Shell has higher intensity, and can accurately controling shell wall thickness.
Specific implementation mode
Presently in connection with specific embodiment, the present invention is further illustrated.
A kind of method of cold-drawn air-conditioner compressor outer housing, includes the following steps：
1. choosing welded tube, then welded tube is handled welded tube through cold-drawing technology through pickling → phosphatization → saponification process；Welded tube passes through
Saw material is carried out after cold-drawn to control size.
2. the welded tube after cold-drawn is carried out temper；Specifically, in tempering, welded tube is placed in tempering furnace, is returned
At 600-850 DEG C, tempering furnace is sealed 2-6 hours for fiery temperature control, is then opened tempering furnace and is cooled down automatically.
3. taking out welded tube, welded tube surfaces externally and internally finish is controlled, controls length.Specifically, then the welded tube taken out carries out
Rise endoporus for pickling → polishing inside and outside welded tube →, and length → gas pressure test, inspection are controlled for controlling internal diameter → Vehicle Processing welded tube both ends
Survey air-tightness → cleaning of welded tube welding seam.
The advantages of processing method, what is selected when selection is welded tube, selection welded tube is：Welded tube is by hot-rolled sheet coil
At by directly controlling the thickness of hot rolled plate, so as to accurately control the wall thickness of pipe fitting, and then being precisely controlled after cold-drawn
The wall thickness of shell promotes the machining accuracy of entire cold-drawn air-conditioner compressor outer housing.
Next is the increase in the processing step of tempering, although welded tube hardness after cold-drawn increases, material can become
Embrittlement, welded tube be easy cracking, to be unfavorable for carry out subsequently in welded tube in the following process being punched out, now by cold-drawn it
Welded tube afterwards is tempered, and material is made to be restored, to increase the intensity of welded tube.
It is enlightenment with above-mentioned desirable embodiment according to the present invention, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to determine its technical scope according to right.
