Abstract
The invention discloses a method for manufacturing an oil pump gear by powder metallurgy, which comprises the following steps: firstly, mixing the iron powder, and then, pressing, sintering and shaping; after shaping, processing by a numerical control machine tool; turning an inner hole end surface, grinding two end surfaces, chamfering an internal angle and an external angle, and polishing; and then, carrying out oil immersion and packaging to obtain a finished product. The invention simplifies the production process of the product, reduces the cost, improves the technical accuracy of the product, and ensures the quality of the product.
Description
Technical field
The present invention relates to a kind of method of powder metallurgy maker oil pump gear.
Background technology
PM technique is a comprehensive stronger technology inter-trade, interdisciplinary, and it is along with other science and technology development, also in the technical merit that constantly improves self.
Powder metallurgical technique is to produce various machine components with the method for die forming, compares with traditional mechanical processing technique, it is advantageous that its few cutting and does not have cutting, is good at high production rate, low cost especially.So it is the clear superiority of this technology that reduced investment, efficient height, cost hang down.
China's powder metallurgy industry has developed nearly 50 years, no matter technology or scope of the enterprise have all had quite high level.
But existing oil pump gear processing method is also more loaded down with trivial details, complex process, after repressed behind the iron powder batch mixing, sintering, shaping, process with machine tool, need car endoporus, whole endoporus, again car first end face, car second end face, plain grinding biend, fall in exterior angle, roll flute tip circle, deburring, immersion oil pack finished product.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art, and a kind of method of powder metallurgy maker oil pump gear is provided, and it has simplified product processes, reduces cost; Improve the product technology precision, guaranteed product quality.
For addressing the above problem, the present invention adopts following technical scheme:
The invention provides a kind of method of powder metallurgy maker oil pump gear, the prior step of described method is by repressed behind the iron powder batch mixing, sintering, shaping, processes with Digit Control Machine Tool after the shaping.
Described Digit Control Machine Tool procedure of processing comprises: hole end surface, mill biend in the car, fall in exterior angle, light decorations back immersion oil pack finished product.
The invention provides Digit Control Machine Tool processing, simplified product processes, reduce cost; Improve the product technology precision, guaranteed product quality.
Advantage of the present invention has:
1, manufacturing procedure shortens 1/3.
2, change digital control processing into by the common process lathe, process technology improves very big.
3, machining accuracy improves greatly, brings up to 0.015 as end face run-out by original 0.03.
4, yield rate improves greatly, and originally yield rate brings up to 92% now 85%.
Because the improvement of technology, the raising of precision, on the product quality step.
The specific embodiment
By repressed behind the iron powder batch mixing, sintering, shaping, after the shaping with Digit Control Machine Tool processing, in car hole end surface, mill biend, fall in exterior angle, light adorn after immersion oil pack finished product.
1, manufacturing procedure shortens 1/3.
2, change digital control processing into by the common process lathe, process technology improves very big.
3, machining accuracy improves greatly, brings up to 0.015 as end face run-out by original 0.03.
4, yield rate improves greatly, and originally yield rate brings up to 92% now 85%.
Because the improvement of technology, the raising of precision, on the product quality step.
It should be noted that at last: obviously, the foregoing description only is for example of the present invention clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among protection scope of the present invention.
Claims (2)
1. the method for a powder metallurgy maker oil pump gear, the prior step of described method is by repressed behind the iron powder batch mixing, sintering, shaping, it is characterized in that: process with Digit Control Machine Tool after the shaping.
