1.冷挤压工艺冷挤压工艺是将金属材料经软化后,在室温条件下,借助模具在外力作用下,使金属材料发生塑性变形,以获得所需零件的几何形状和精度。它具有提高材料利用率,改善金属内部组织,提高工件机械性能指标等特点。同时工艺简单,节约能源,生产效率高,且便于生产的机械化和自动化。 2.温锻技术温锻是七十年代左右发展的新工艺。它的主要特点是把坯料加热到再结晶温度以下进行
1. Cold extrusion process Cold extrusion process is the metal material after the softening, at room temperature, with the help of external force in the mold, the plastic deformation of the metal material to obtain the required parts geometry and accuracy. It has the characteristics of improving the material utilization, improving the internal structure of the metal and improving the mechanical properties of the workpiece. At the same time, the process is simple, energy saving, high production efficiency, and easy mechanization and automation of production. Warm forging technology Warm forging is the development of the new technology around the seventies. Its main feature is the heating of the blank below the recrystallization temperature
