Embodiment Construction

[0016] A method for preparing an automobile water pump hub, characterized in that it comprises the following steps:

[0017] (1) Design the mold according to the technical requirements of the hub;

[0018] (2), then the weight ratio of the prepared components is: reduced iron powder 95-97, add graphite 0.5-1.5, copper powder 1-2, electrolytic nickel 1-1.5, sulfur 0.1-0.5, and then add 0.8-1 hard Zinc fatty acid and engine oil are first mixed manually, and then put into a special double-cone mixer for full mixing. The mixing time is 40-60 minutes;

[0019] (3), and then adopt fully automatic split multi-stage floating mold base, 300-400 tons of automatic hydraulic press, through multi-stage floating, automatic numerical control powder feeding, so that the product can be formed at one time;

[0020] (4) Then, the formed product is sintered in an automatic mesh belt furnace sintering furnace, nitrogen is used as a protective atmosphere, and the sintering temperature is controlle...

Abstract

The invention discloses an automobile water pump hub preparation method, comprising the following steps: iron powder is reduced with the material of powder metallurgy, copper powder, nickel powder, molybdenum powder, additives such as sulfur and the like are added, by scientific formulation and reasonable production method, the water pump hub is formed in one step by a high tonnage hydraulic machine and then the obtained product is sintered and after one more mold cover half shaping and high temperature steam nigrescence rust-proof treatment, the finished product is obtained. The invention has the advantages of simple operation, low production cost, time and labor saving, good overall performance and high intensity and precision.

Description

technical field [0001] The invention relates to a method for preparing automobile parts, in particular to a method for preparing an automobile water pump wheel hub. Background technique [0002] The automobile water pump hub is an important component of the water pump of cars and light automobiles, and is the transmission part of the water pump power. The appearance feature is a square petal shape, and there is a screw positioning hole in the center of the four petals, which is used to fix the pulley. Ordinary steel parts are used, the surface is coated with anti-rust oil for anti-rust treatment, and the surface hardness is HRB60--75. Since this part is a key part of the automobile water pump, the coaxiality, concentricity, four-petal beating and the surface of the inner hole The smoothness has high requirements, and its quality directly affects the smooth operation of the pump. The existing water pump hub is made of steel parts through cutting, flat grinding, and mechanic...
