What are the problems and solutions in the manufacturing process of transmission shaft forgings?

The problems prone to occur in the manufacturing process of transmission shaft forging and the solutions are as follows:

Poor surface quality: In the forging process, if the temperature is not properly controlled or the forging is not uniform, it will lead to cracks, oxidation skin, folding and other problems on the transmission shaft forging surface. The solution is to strictly control the forging temperature and forging speed to ensure the uniformity and continuity of the forging process, while using the appropriate heat treatment process to improve the surface quality.

Size deviation: Due to mold wear or manufacturing errors, the actual size of the gearbox shaft forging may be different from the design size. The solution is to regularly detect and correct the mold size, and use precision processing equipment and technology to improve the manufacturing accuracy.

Internal defects: During the forging process, due to defects in the material or improper heat treatment, cracks, pores, inclusions and other defects may occur inside the gearbox shaft forgings. The solution is to select high-quality materials, use reasonable heat treatment process and strict quality control procedures to ensure the stability and reliability of the internal quality of the material.

Mechanical properties are not up to standard: If the material selection is improper or the heat treatment process is incorrect, it may lead to the mechanical properties of the gearbox shaft forgings are not up to standard. The solution is to choose the appropriate material and heat treatment process, according to the material characteristics to develop a reasonable processing and heat treatment program to ensure that it has excellent mechanical properties.

Processing difficulties: Due to high material hardness or improper processing technology, it may lead to difficult processing of gearbox shaft forgings. The solution is to use reasonable heat treatment process and processing equipment to improve processing efficiency and accuracy, while paying attention to prevent deformation and residual stress in the processing process.

In short, in the manufacturing process of transmission shaft forgings, it is necessary to strictly control material quality, manufacturing process and heat treatment process, while strengthening quality detection and data analysis, timely discovery and solution of problems to ensure that its quality and performance meet the design requirements.
