It is sequentially sleeved on bent axle along the axial direction of bent axle, forms dynamic sealing, cylinder interior is divided into two gas chambers of high-low pressure, in song
Under the drive of axis, air-breathing, the process of compression, exhaust are completed.
Currently, the preparation about bearing, mainly uses integral casting process, such as sand casting etc. is to melt cast iron
It is bearing unitary solid blank to be cast in die for molding after liquid, it is real then passes through the multiple working procedures such as roughing, finishing
The technique of existing base bearing and supplementary bearing.For the technique there are flow complexity, processing efficiency is low, of high cost；Processing conditions is severe, to ring
Border pollutes；Also, processing waste material is more, the problem of leading to the wasting of resources.
Invention content
The present invention is intended to provide a kind of production method of bearing of compressor, this method are simple for process, at low cost.
In order to achieve the above technical purposes, the present invention makes bearing of compressor using the method for seperated welding, specific as follows：
A kind of production method of bearing of compressor, the bearing setting are used for the centre bore A that bent axle passes through and include method
Blue portion and collar, the flange portion be arranged the collar end periphery, the centre bore A through the collar with
Flange portion；It is characterized in that：Using seperated welding procedure, comprise the following processes：
Using tablet steel, according to the flange portion shape and size, the flange with centre bore B is made using Sheet Metal Forming Technology
Portion；
The collar with centre bore A is processed according to the collar shape and size using steel pipe or casting tubing；
Collar is connected in flange portion side, keeps the centre bore A and centre bore B coaxial, is then welded, make flange
Portion is fixedly connected with collar, obtains the bearing.
As the first realization method, the collar, which is inserted into the centre bore B, forms close-fitting connection,
That is, gapless between the inner wall and collar outer rim of centre bore B, close mating, the end face of the centre bore B with
The seam crossing of collar outer rim is welded, and the bearing is obtained.
As second of realization method, the collar is inserted into formation pine in centre bore B and matches, that is, the collar outer rim
Diameter is less than the internal diameter of centre bore B, gap is deposited between the inner wall of centre bore B and the collar external profile diameter, in the gap
Position is welded, and flange portion is made to be fixedly connected with collar, obtains the bearing.
As the third realization method, interference connection is formed in the collar indentation centre bore B, that is, the collar
External profile diameter is more than the internal diameter of centre bore B, the collar is pressed into centre bore B under external force, in the centre bore B
End face and the seam crossing of collar outer rim welded, obtain the bearing.
In view of the bearing is in the mechanical property of connecting portion, preferably the first realization method makes the bearing.
The steel are unlimited, including carbon steel and steel alloy.
The casting tubing is ironcasting, is to use casting technique, cast iron is melted to be poured into a mould in a mold after liquid
It is shaped to tubular blank, then passes through the tubing that processing obtains.
Preferably, the internal diameter of the steel pipe is equal to the diameter of the centre bore A；The internal diameter of the casting tubing is through finishing
It is equal to the diameter of the centre bore A after work.
The welding manner is unlimited, including melting welding, soldering, Laser Welding etc..
The shape of the flange portion is unlimited with structure, may include some can stamping forming structural unit, such as gas
Hole, pilot hole etc..
Compared with the production method of existing bearing of compressor, the invention has the advantages that：
(1) present invention utilizes molding steel plate, according to required flange portion shape and size, punching press manufacturing flange portion, and
Can punching press be made in the flange portion some can the multiple hole position such as stamping forming structural unit, such as stomata, pilot hole, save
But the processing technology for being made when casting technique and also needing to carry out after spray is used.
The present invention is using molding steel pipe or casting tubing, according to the shape and size of required collar, processing and fabricating axis
Neck, is directly utilized the trepanning feature of tubing, can be obtained collar by simple processing technology, with existing casting technique
Compared to processing capacity is reduced, material has been saved.
Flange portion obtained is directly attached with collar using seperated soldering mode and be can be obtained by the present invention
The bearing, the mechanical property of connecting portion can be ensured by especially carrying out welding after using close-fitting connection, improve reliability.Cause
This, manufacture craft of the invention is simple, at low cost, and environment friendly and pollution-free.
(2) present invention directly carries out bearing portions or whole components making using steel, since steel are with good
Good dimensional accuracy, intensity, hardness, rigidity and elasticity modulus, therefore can ensure bearing integral strength and hardness, while can
The dimensional accuracy for ensureing processing bearing obtained, has a good application prospect.
