Gear shaft forging is a typical mechanical transmission component widely used in various industrial fields. In the process of gear shaft forging processing, the technique is a crucial factor. This paper will classify and compare common gear shaft forging processing techniques.
I. Classification by material state
Heat treatment process: This process is suitable for high-strength, high-hardness gear shaft forgings. This technique requires quenching or tempering to increase the hardness and strength of the gear shaft forgings.
Cold treatment process: This process is suitable for low-strength, low-hardness gear shaft forgings. This technique does not require high-temperature treatment, only cooling is necessary.
II. Classification by shape
Gear rolling process: This process can produce cylindrical gear shafts with different modules, pressure angles, and angles. The advantages of this process are high efficiency and good quality, but it has limitations.
Gear hobbing process: This process uses cutting to manufacture gear shaft forgings of different shapes. The advantage of this process is high machining accuracy, but it has a lower production efficiency.
III. Classification by equipment
Traditional mechanical processing process: This process requires traditional mechanical equipment such as lathes, milling machines, etc. The advantage of this process is the simplicity of the equipment, but the machining efficiency is low.
CNC machine tool processing technology: This process uses digital control technology for gear shaft forging processing, with the advantages of high machining accuracy and speed. However, the equipment price is relatively high, and there are higher skill requirements for operators and maintenance personnel.
IV. Classification by manufacturing process
Radial forging process: This process is suitable for the production of gear shaft forgings within various yield strength ranges. By applying axial and radial pressure to the steel bar in a cold state, the metal undergoes plastic deformation to achieve forging forming.
Free forging process: This process is suitable for the production of gear shaft forgings of any shape. By applying hammering force between two concentric cylindrical surfaces, the metal undergoes plastic deformation under pressure to achieve forging forming.
In summary, gear shaft forging processing technology is a complex project that requires selecting and applying techniques based on specific situations in actual production. The application of different techniques will impact the quality and cost of gear shaft forgings. Therefore, in the production process, in-depth analysis and comparative research are needed to find the most suitable technological solution.
