Motorcycle copper alloy forging is one of the important parts commonly used in motorcycle manufacturing. Through the cold processing process, the copper alloy material can be made to have good strength, toughness and wear resistance, thereby improving the performance and reliability of the motorcycle. This paper will explore the cold processing technology of motorcycle copper alloy forgings.
First of all, the cold working process includes two main steps: forging and quenching. Forging refers to the plastic deformation of copper alloy material by applying force to make it plastic deformation at room temperature, so as to obtain the desired shape and size. In the manufacture of motorcycle copper alloy forgings, there are two common forging methods: cold forging and stamping.
Cold forging is the use of cold plastic deformation characteristics of forging. First, the copper alloy blank heated to the appropriate temperature is placed in the die of the cold forging machine, and then the appropriate force is applied to press, so that the copper alloy blank plastic deformation, and gradually fill the mold chamber, and finally get the desired shape. Cold forging can make the grain of copper alloy finer, improve its strength and toughness, and will not cause grain growth and deformation and softening phenomenon.
Stamping is the process of plastic deformation of copper alloy sheet by punching press. First, a sheet of copper alloy heated to the appropriate temperature is placed in a punch die, and then an impact force is applied to make it plastic deformation, and finally the desired shape is obtained. Stamping can efficiently process complex shapes of motorcycle copper alloy parts, and can maintain high accuracy and surface quality.
After the forging is completed, it is also necessary to quench the motorcycle copper alloy forgings. Quenching refers to heating the forgings to the appropriate temperature and then cooling them quickly to improve their microstructure and properties. By quenching treatment, the grains of copper alloy forgings can be finer and more uniform, and the hardness and wear resistance can be improved. Quenching methods commonly used are water quenching, oil quenching and gas quenching.
In addition to forging and quenching, there are a number of other cold working processes that can be used to improve the performance of motorcycle copper alloy forgings, such as stretching, cold extrusion, etc. These processes can further change the shape and structure of copper alloy forgings to adapt to different stress conditions and use environments.
In summary, the cold working technology of motorcycle copper alloy forgings plays an important role in improving its performance and reliability. Through reasonable selection and control of forging methods, quenching methods and other cold working processes, copper alloy forgings can be made with higher strength, toughness and wear resistance to meet the requirements of motorcycles in different working conditions.
