Description
Technical field
The present invention relates to counterbalance weight and manufacture method thereof for a kind of compressor.
Background technology
Counterbalance weight is the vitals of compressor rotor, plays balance, noise reduction, damping effect.To counterbalance weight, except the density of having relatively high expectations, outside more accurate dimensional precision and higher weight precision, generally also require not carrying magnetic and be not magnetized, counterbalance weight band is magnetic can affect compressor operating efficiency.Counterbalance weight also requires antirust, otherwise can cause compressor inside to occur quality problems.
Another comparatively serious technical problem is: traditional technique, in the mixing of material and the temperature of compression molding, be 60-150 ℃ of left and right, differ with the temperature of firing (more than 1100 degree high-temperature firing) excessive, cause the change in process expanding with heat and contract with cold of part larger, be difficult to control, the dimensional change that causes forming by a firing rear product is large, is difficult to meet high-precision requirement, and the inherent tissue of metal is not so good.
How to pass through to improve alloy component and proportioning for counterbalance weight, production performance is better, without the antirust counterbalance weight of magnetic, is industry urgent problem.
Summary of the invention '
The object of this invention is to provide a kind of satisfied with the antirust requirement of magnetic, the compressor counterbalance weight that production performance is better.
Another object of the present invention is to provide the manufacture method of counterbalance weight for a kind of compressor, 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, by powdered alloy, by powder metallurgy process, made, 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 that accounts for first three kind component gross weight 1-2%.
Caking agent described above is stearic acid.
A manufacture method for counterbalance weight for compressor, comprises the steps:
A) be equipped with first in proportion starting material standby, then each alloy material carried out to preheating at 200-250 ° of C;
B) powdered alloy after preheating is added to caking agent, stir, and be again heated to 400-500 ℃, delivering powder press is pressed, and makes counterbalance weight pressed compact;
C) counterbalance weight pressed compact is placed in to sintering oven sintering curing, manufactures counterbalance weight sintered blank, sintering temperature 950-980 ℃;
D) to the deburring of polishing of counterbalance weight sintered blank.
Compared with prior art, the present invention has the following advantages: 1, by selecting rational formula constituent and content, the compressor of acquisition has good in magnetic rustless property with counterbalance weight.2, the counterbalance weight dimensional stabilizing that the present invention produces, production performance is good.3, production process non-oxidation of the present invention, the inherent tissue of metal is good.4, the present invention first by each material 200-250 ℃ of preheating, the scope heating at 400-500 ℃ to mixing material again, then at 950-980 ℃, carry out sintering, whole process temperature rising, the temperature difference is relatively little, and after part sintering, size is easy to control, effectively guarantee the precision of part, distortion reduced in size, has improved the quality of product, and the inherent weave construction of metal is better.
