Description

A kind of production method of bearing of compressor
Technical field
The present invention relates to Compressor Technology field more particularly to a kind of production methods of bearing of compressor.
Background technique
Rotary compressor for refrigerant because its high cooling efficiency, it is compact-sized, small in size, light-weight due to be widely used in household Inside equal air conditioners.
Compression assembly is the pith in rotary compressor for refrigerant, mainly includes cylinder, piston, slide plate, crankshaft, master Bearing and supplementary bearing.Slide plate is located in cylinder sliding vane groove, and arc end surface connects with piston face, upper bearing (metal), piston, lower bearing It is sequentially sleeved on crankshaft along the axial direction of crankshaft, 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 then real by multiple working procedures such as roughing, finishing The technique of existing base bearing and supplementary bearing.For the technique there are process complexity, processing efficiency is low, at high cost;Processing conditions is severe, to ring Border pollutes;Also, the problem of processing waste material is more, leads to the wasting of resources.
Summary of the invention
It is this method simple process, at low cost the present invention is intended to provide a kind of production method of bearing of compressor.
In order to achieve the above technical purposes, the present invention makes bearing of compressor using the method for whole forging and forming, specifically It is as follows:
A kind of production method of bearing of compressor, the bearing setting are used for the centre bore A that crankshaft passes through and including methods Blue portion and collar, the flange portion are arranged in the periphery of described collar one end, the centre bore A through the collar with Flange portion;It is characterized in that:The bearing is made using steel plate forging and stamping.
The bearing can also include turn-up portion, and the turn-up portion be fixedly connected on the flange portion outer peripheral edge, and described Flange portion forms the flange towards the collar other end.
The forging and stamping are that forging and punching press are collectively referred to as, and are to apply pressure to blank using metal forming machinery or by mold, make Generation plastic deformation, thus obtain needed for shape and size product method for processing forming.Wherein, punching press is a kind of utilization Press machine and mold apply external force to plate, band, tubing and profile etc., are allowed to generate plastic deformation or separation, to obtain The method for processing forming of the stamping parts of required shape and size;Forging be it is a kind of using metal forming machinery to blank apply pressure, make It generates plastic deformation to obtain the processing method with certain mechanical performance, certain shapes and size forging.In forging technology Including cold-heading and hot upsetting.In order to improve the structure precision of bearing, preferably, steel plate forging and stamping are progress essence after required bearing arrangement Processing.
The settable structural unit with certain function on the bearing.It, can when the structural unit is arranged on bearing With after steel plate forges and presses, further processing makes the structural unit;It, can also for structural unit made from certain malleable pressures With directly these structural units etc. are made in forging and stamping during steel plate forges and presses.For example, when the structural unit is for being vented, pacifying , can be after steel plate forging and stamping when the through-hole of dress etc., further processing makes the through-hole;It can also be straight during steel plate forges and presses It connects forging and stamping and the through-hole is made, still, through-hole lesser for size makes using after steel plate forges and presses, such as forges in steel plate These through-holes are made by the method to drill after pressure.
The steel plate is unlimited, including carbon steel plate and alloy-steel plate.
Compared with existing bearing of compressor production method, the invention has the advantages that:
(1) present invention utilizes molding steel plate, according to the shape and size of required bearing, directly forging and stamping production bearing, and And the structural units such as malleable stomata, mounting hole for suppressing to be located on bearing, have manufacture craft simple, it is at low cost, and ring Protect free of contamination advantage.
(2) present invention is directly made using steel, since steel have good dimensional accuracy, intensity, hardness, just Property and elasticity modulus, therefore can guarantee bearing integral strength and hardness, while can guarantee to process the size of bearing obtained Precision has a good application prospect.
