During the manufacturing process of the mobile phone middle frame, it needs to go through multiple processes such as heating, forging, bending, and trimming to form the final product. Before forging the material, it needs to be heated first to make the material reach the predetermined forging temperature. Therefore, a pre-forging heating device needs to be designed to heat the material before hot forging.

[0003] After the middle frame plate after hot forging forms the required external shape through physical forging, in order to restore the internal microstructure of the material crystal image, a solution heat treatment process needs to be carried out on the middle frame plate after hot forging. After the temperature of the middle frame plate is raised above 460 °C and maintained for a certain time, it is then rapidly cooled and the temperature is quickly reduced. Therefore, based on the solution heat treatment process requirements after hot forging of the middle frame plate, designing an air-cooling machine for a solution heat treatment production line helps to improve the solution heat treatment production efficiency.
