Construction machinery forging die is one of the indispensable key components in the construction machinery manufacturing process, and its quality and performance directly affect the service life and stability of the entire mechanical equipment. In order to improve the wear resistance, corrosion resistance and overall performance of the mold, surface treatment is usually required during the manufacturing process.
In the surface treatment of construction machinery forging die, the commonly used technologies include heat treatment, coating technology and surface modification technology.
First, heat treatment is one of the most common and effective surface treatment techniques. By controlling the heating and cooling process of the material, the structure and hardness of the mold can be changed to improve its wear resistance and corrosion resistance. Common heat treatment methods include quenching, tempering, normalizing and Raystenite transformation.
Secondly, coating technology is also one of the commonly used surface treatment methods. By forming a protective layer of metal or non-metal on the surface of the mold, the wear resistance and corrosion resistance of the mold can be improved. Common plating techniques include electroplating, hot dip plating, physical vapor deposition and chemical vapor deposition.
In addition, surface modification technology has been gradually applied. By forming a mechanical strengthening layer or a chemical modification layer on the surface of the mold, the hardness, wear performance and corrosion resistance of the mold can be improved. Common surface modification techniques include laser treatment, plasma spraying and ion implantation.
In the application of construction machinery forging die, the choice of surface treatment technology needs to be reasonable according to the specific working environment and requirements. For example, under heavy load and harsh working conditions, priority should be given to the use of high strength and high wear resistance surface treatment technology to improve the service life and reliability of the mold. For working environments that require corrosion resistance and anti-adhesion, a coating technology with good corrosion resistance and low friction coefficient can be given priority.
In summary, the surface treatment technology of construction machinery forging die plays a crucial role in improving the wear resistance, corrosion resistance and overall performance of the die. In the selection and application of surface treatment technology, it is necessary to make a reasonable choice according to the specific requirements and working environment to ensure the stable operation of the mold and extend its service life.
