Description
Technical field
The present invention relates to a kind of compressor counterbalance weight and manufacture method thereof.
Background technology
Counterbalance weight is the vitals of compressor rotor, plays balance, noise reduction, damping effect.To counterbalance weight, except requiring higher density, outside more accurate dimensional precision and higher weight precision, generally also require not carrying magnetic and not being magnetized, counterbalance weight band is magnetic can affect compressor operating efficiency.Counterbalance weight also requires antirust, otherwise compressor inside can be caused to occur quality problems.
Another comparatively serious technical problem is: traditional technique, it is about 60-150 DEG C in the mixing of material and the temperature of compression molding, excessive with the temperature difference fired (high-temperature firing of spending 1100) more, cause the change in process expanded with heat and contract with cold of part larger, be difficult to control, cause the dimensional change forming by a firing rear product large, be difficult to meet high-precision requirement, and metal inherence tissue is not so good.
How to pass through to improve counterbalance weight alloy component and proportioning, production performance is better, without the counterbalance weight that magnetic is antirust, is industry urgent problem.
Summary of the invention
The object of this invention is to provide a kind of satisfied requirement antirust without magnetic, the compressor counterbalance weight that production performance is better.
Another object of the present invention is to provide a kind of manufacture method of compressor counterbalance weight, the product size good stability of acquisition.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of compressor counterbalance weight, made by powder metallurgy process by powdered alloy, it is characterized in that: the weight percent of described powdered alloy starting material each component consists of: manganese (Mn) 14-30%, copper (Cu) 5-30%, chromium (Cr) 1-10%, surplus is Fe, and adds the caking agent accounting for first three kind component gross weight 1-2%.
Caking agent described above is stearic acid.
A manufacture method for compressor counterbalance weight, comprises the steps:
A) be equipped with starting material first in proportion for subsequent use, then preheating carried out at 200-250 ° of C to each alloy material;
B) powdered alloy after preheating is added caking agent, stir, and be again heated to 400-500 DEG C, delivering powder press is pressed, obtained counterbalance weight pressed compact;
C) counterbalance weight pressed compact is placed in sintering oven sintering curing, manufactures counterbalance weight sintered blank, sintering temperature 950-980 DEG C;
D) polishing deburring is carried out to counterbalance weight sintered blank.
Compared with prior art, the present invention has the following advantages: 1, by selecting rational formula constituent and content, and the compressor counterbalance weight of acquisition has excellent in magnetic rustless property.2, the counterbalance weight dimensional stabilizing of the present invention's production, production performance is good.3, production process non-oxidation of the present invention, metal inherence tissue is good.4, the present invention first by each material 200-250 DEG C of preheating, again to the scope heating of mixing material at 400-500 DEG C, then sinter at 950-980 DEG C, whole process temperature slowly rises, and the temperature difference is relatively little, and after part sintering, size is easy to control, the precision of effective guarantee part, distortion reduced in size, improves the quality of product, and the inherent weave construction of metal is better.
