As one of the important parts of motorcycle, the surface quality of motorcycle forging is very important. Some common problems make the surface quality of motorcycle forgings can not meet the requirements, such as rust, damage, oxidation, cracking and so on. The following will explore the causes of these common problems and solutions, in order to help motorcycle manufacturers overcome these problems and improve the surface quality of motorcycle forgings.
Rust: Motorcycle forgings exposed to the air for a long time are susceptible to oxidation and corrosion, resulting in rust and oxidation marks on the surface of the forgings.
Solution: In the production process, after the forging is completed, shot blasting must be carried out in time to remove the oxide layer and rust spots on the surface of the forging. At the same time, it is also necessary to anti-corrosion treatment of forgings, commonly used anti-corrosion methods include spray painting, paint, passivation and other methods.
Damage: Wear, scratches or knocks during operation, resulting in scratches or dents on the surface of motorcycle forgings.
Solution: The use of advanced heat treatment technology, such as carburizing, quenching and other process treatment methods can effectively improve the surface hardness and toughness of the forging, improve its damage resistance. At the same time, protection measures should be strengthened in the assembly process to avoid damage to the forging surface caused by hammering, friction, impact and other behaviors.
Oxidation: The forgings are exposed to the air without surface treatment, or have been improperly processed, resulting in oxidation problems on the surface of the forgings.
Solution: For forgings stored for a long time, passivation, painting or other surface treatment can be carried out after cleaning. For forgings being processed, the operator should use the appropriate cutting speed and cutting fluid to avoid oxidation problems during surface processing.
Cracks: The forgings are subjected to excessive tensile deformation, or uneven contraction stress when cooling, resulting in cracks on the surface of the motorcycle forgings.
Solution: The forging temperature and strength should be strictly controlled, and appropriate water cooling and heat treatment processes should be used to reduce the thermal deformation and internal stress on the forging surface. For forgings that have cracks on the surface, special welding methods can be used to repair them and rework them to meet the requirements of use.
In the production process of motorcycle manufacturing enterprises, the surface quality of motorcycle forgings is very important to the performance and quality of the entire product. Therefore, enterprises must adopt corresponding solutions according to the problems on the surface of motorcycle forgings in a timely manner, improve production efficiency and product quality, and ensure product competitive advantage.
