Shafts are indispensable components in the field of machinery manufacturing and are widely used in various transmission systems and rotating equipment. Among them, Forged Shaft occupies a significant position in high-end equipment manufacturing due to its excellent performance and reliability. In this paper, we will discuss the production process of forged shaft, performance advantages and applications in modern industry.

First, the production process of forged shaft

The production process of forged shaft is strict and complex, mainly including the following steps:

Material selection: the choice of material for the forged shaft is critical, usually choose high-strength, high-toughness alloy steel or stainless steel. These materials can ensure that the shaft can still maintain stable performance when subjected to high loads and high-speed rotation.
Unloading and heating: According to the size and shape of the shaft, the selected material is cut into suitable lengths and heated. The heating temperature and time need to be strictly controlled to ensure that the material reaches a suitable plastic state.
Forging: The heated material is put into the forging equipment and deformed by pressure to form the basic shape of the shaft. During the forging process, the forging parameters should be adjusted according to the size and shape of the shaft to ensure the quality of the shaft.
Heat treatment: After the forging is completed, the shaft is heat treated to eliminate the internal stresses generated during the forging process and to improve the organization of the material. Commonly used heat treatment methods include normalizing, quenching and tempering.
Machining and Inspection: The heat-treated shafts are subjected to machining, such as turning, milling and grinding, in order to obtain accurate dimensions and shapes. Finally, the quality of the shaft is ensured to meet the standard through non-destructive testing, metallographic analysis and mechanical property testing.

Second, the performance advantages of forged shaft

Forged shafts have the following performance advantages over other manufacturing methods:

Strength and toughness: the material of forged shaft is subjected to strong plastic deformation during the forging process, which makes the grain of the material refined and the organization structure more compact. This structure makes forged shafts have higher strength and toughness, and can withstand greater loads and impacts.Wear resistance and corrosion resistance: the surface of forged shaft has high hardness and wear resistance after machining and heat treatment. At the same time, due to the material itself has good corrosion resistance, forged shafts can still maintain good performance in harsh environments.
Precision and stability: The production process of forged shafts is strictly controlled, which can ensure the precision of the size and shape of the shaft. In addition, the material and structural stability of forged shafts are good, so that the shafts can still maintain stable performance during long-term use.
