The oil pump drive sprocket is an important part of the oil pump of the automobile engine, and its accuracy directly affects the performance of the oil pump. The part is generally made of powder metallurgy parts, which can produce high quality parts at a lower cost.
And with the continuous development of the powder metallurgy process, powder metallurgy parts have become a high-quality part with light weight, high strength, wear and corrosion resistance. In practical applications, powder metallurgy parts are mainly used to manufacture gears, racks and other parts.
In the oil pump transmission sprocket powder metallurgy manufacturing process, because its products are powder metallurgy parts, it is difficult to ensure the production accuracy in the actual production. For this reason, under the premise of ensuring product quality, how to improve production efficiency, reduce costs and reduce labor intensity has become an important research topic.
Powder metallurgy technology to prepare the oil pump drive sprocket
Oil pump drive sprocket is generally manufactured using powder metallurgy technology, its specific manufacturing process is: a certain composition of raw materials (iron powder, metal powder, etc.) in the mold pressed into a certain shape and size of the blank, and then heated to a certain temperature, so that the formation of alloy powder with a certain density and mechanical properties.
The powder is put into the vacuum sintering furnace, and the high temperature generated by the vacuum sintering furnace is used to sinter the metal, so that a dense organization is formed inside the metal to meet the design requirements. Then the powder is sent into the vacuum furnace for sintering treatment, so that the oil pump drive sprocket is made.
Oil pump drive sprocket parts using powder metallurgy technology manufacturing process is as follows: first of all, the raw materials for processing, including machining, heat treatment, etc.; and then put the alloy powder into the vacuum sintering furnace, the use of high temperature produced by the vacuum sintering furnace sintering of the metal interior.
Then it will be cooled to room temperature and then processed on the hot mill for hot grinding. Because the oil pump transmission sprocket parts have the advantages of high precision, high strength, good wear resistance, etc., they are generally manufactured by hot grinding technology in actual production.
