Abstract
The utility model relates to a powder metallurgical compressor valve plate for a refrigerator, comprising a valve plate body pressed by metal powder, and an air suction port, an air exhaust port, installing holes, and valve piece installing grooves arranged at the air suction port and the air exhaust port, which are arranged on the valve plate body. The powder metallurgical compressor valve plate is characterized in that: the depth of parallelism of the upper surface and the lower surface of the valve plate body is 0 to 0.05mm, and the planeness thereof is 0 to 0.05mm; and the planeness of valve surface lines of the air suction port and the air exhaust port is 0 to 0.015mm. The valve plate adopting the structure and pressed and formed by a numerical control hydraulic press saves the grinding processing of two big planes, and saves the processing procedure; the high accurate valve surface line structure reduces grinding quantity of the machining, and reduces waste of the materials, thus reducing manufacture cost and increasing production efficiency.
Description
Technical field
The utility model belongs to powder metallurgical technology, particularly relates to a kind of refrigerator powder metallurgy compressor valve plate.
Background technique
At present, the compressor valve plate, it is one of strength member in the freezer compressor, refrigeration to compressor has immeasurable effect, the valve plate of existing compressor mainly comprises, valve plate body, the intakeport that on the valve plate body, is provided with, relief opening, mounting hole and at the valve block mounting groove of intakeport and exhaust ports, and the parallelism of two planes and the planeness of existing valve plate are bigger, be generally 0.1～0.15mm, also need the processing once more of double face abrading machine in addition; The valve face line precision of intakeport and relief opening is not high, needs grinding to fall bigger surplus, and this kind valve plate blank needs to carry out a large amount of machinings before use, has caused the prolongation of operation, and the waste of material has reduced working efficiency.
Summary of the invention
The utility model provides a kind of course of working, reduction product reject rate of exempting follow-up complexity, a kind of refrigerator powder metallurgy compressor valve plate of increasing work efficiency for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of refrigerator powder metallurgy compressor valve plate, comprise the valve plate body that the metallic dust compacting forms, the intakeport that on the valve plate body, is provided with, relief opening, mounting hole and at the valve block mounting groove of intakeport and exhaust ports, it is characterized in that: the parallelism between two planes up and down of described valve plate body is 0～0.05mm, planeness between two planes is 0～0.05mm, the planeness 0～0.015mm of the valve face line of described intakeport and relief opening.
Advantage and the good effect that the utlity model has are: because the utility model is adopting technique scheme, planeness precision to the parallelism between two big planes of valve plate and each big plane is improved raising, exempted in the following process processing to two big planes, high-precision intakeport and relief opening valve face line have reduced the machining allowance to the valve face line, reduced the waste of material, save rework process, improved manufacturing efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the reverse side structural representation of Fig. 1;
Fig. 3 is the A-A sectional view among Fig. 2.
Among the figure: 1, valve plate main body; 2, intakeport; 2-1, intakeport valve face line; 3, relief opening; 3-1, relief opening valve face line; 4, mounting hole; 5, valve block mounting groove.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment:
See also Fig. 1 to Fig. 3, a kind of refrigerator powder metallurgy compressor valve plate, comprise the valve plate body 1 that the metallic dust compacting forms, the intakeport 2 that on the valve plate body, is provided with, relief opening 3, mounting hole 4 and at the valve block mounting groove 5 at intakeport 2 and relief opening 3 places, it is characterized in that: the parallelism between two planes up and down of described valve plate body 1 is 0～0.05mm, the parallelism on two planes is 0.05mm in the present embodiment, planeness between two planes is 0～0.05mm, the parallelism on two planes is 0.05mm in the present embodiment, planeness 0～0.015mm of described intakeport valve face line 2-1 and relief opening valve face line 3-1, the parallelism on two planes is 0.015mm in the present embodiment.Therefore the valve plate of the utility model structure has been exempted in the subsequent handling processing to two big planes, intakeport of the present utility model and relief opening valve face line have reduced the machining allowance to the valve face line, reduce the waste of material, saved rework process, improved manufacturing efficiency.
