Abstract

The invention provides a liquid-state die forging process for a cam shaft gear for an automobile engine. The liquid-state fie forging process comprises the following steps of: 1) smelting; 2) mould designing; 3) liquid-state die forging; 4) normalizing; 5) turning; 6) carburizing and quenching; 7) tempering; 8) grinding; 9) shot blasting and flaw detecting; 10) phosphorus saponification treatment, clearing, polishing and anti-rust oil coating. The process adopts a liquid-state die forging process to carry out gear processing forging, saves labor and energy, and is high in material utilization rate; blank is close to a final processing gear of a cam shaft gear, and die forging quality is high; the obtained gear is high in hardness, is good in wear resistance, is high in corrosion resistance and is low in forging cost; and the forging process is environmentally-friendly.

Description

technical field [0001] The invention relates to a liquid die forging process for a camshaft gear used in an automobile engine. Background technique [0002] The car engine is the engine that provides power for the car. It is the heart of the car and affects the power, economy and environmental protection of the car. According to different power sources, automotive engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids. [0003] The camshaft is a component in a piston engine. Its function is to control the opening and closing of the valve. Although the speed of the camshaft in a four-stroke engine is half that of the crankshaft (the speed of the camshaft is the same as that of the crankshaft in a two-stroke engine), it usually still has a high speed and needs to withstand a large torque, so the design of The camshaft has high requirements on strength and support, and its material is generally special cast iron, and occasionally f...
