What is automobile valve forging?

Automobile valve forging refers to the valve component used in the automobile engine, usually manufactured by forging process. This paper will introduce the definition, function, manufacturing process and material selection of automobile valve forgings in detail.

First of all, the automobile valve forging is one of the important parts in the engine, mainly used to control the intake and exhaust process. It plays a role in controlling the amount and flow direction of gas in the cylinder, which directly affects the performance and combustion efficiency of the engine. Therefore, the quality and performance of automobile valve forgings are crucial to the normal operation of the engine.

Secondly, automobile valve forgings are manufactured by forging process. Forging is a metalworking process that changes the shape and structure of metal materials by heating and plastic deformation. In the manufacturing process of automobile valve forging, it is necessary to select the appropriate forging equipment and process parameters, forge according to the design requirements and material characteristics, and then carry out heat treatment and finishing and other processes, and finally get the automobile valve forging that meets the requirements.

Material selection is also very important in the manufacture of automobile valve forgings. Commonly used materials include high temperature alloy steel, cast titanium alloy, etc. These materials have good high temperature strength and wear resistance, and can meet the working requirements of the engine in high temperature and high pressure environment. In addition, heat treatment and surface treatment of the material are required to improve its hardness, corrosion resistance and fatigue life.

The quality of automobile valve forging is directly related to the reliability, economy and environmental protection performance of the engine. Therefore, in the automobile manufacturing process, the manufacturing quality of the valve forging must be strictly controlled to ensure that its dimensional accuracy, material properties and surface quality meet the design requirements. At the same time, for modern automotive engines, in order to further improve combustion efficiency and reduce emissions, automotive valve forgings are also constantly innovating and improving, using new processes and new materials such as lightweight design, coating technology and composite materials to meet the needs of environmental protection and energy conservation.

To sum up, the automobile valve forging is an important part of the automobile engine, used to control the amount and flow direction of the gas in the cylinder. The automobile valve forging made by forging process has good performance and durability, and can meet the high temperature and high pressure working requirements of the engine. In the automobile manufacturing process, it is necessary to pay attention to the quality control and technological innovation of valve forgings to continuously improve the performance of the engine and environmental protection indicators, and promote the sustainable development of the automobile industry.
