冷挤压工艺是一项少无切削新工艺。近年来国内外对这一新工艺都十分重视,并不断扩大其使用范围。从日用五金、仪表电器到汽车拖拉机、航空航海工业方面都大量采用这一新工艺。所用的材质也从有色金属逐步过渡到黑色金属、不锈钢、乃至高速钢。这一新工艺在推广使用过程中,由于具有许多显而易见的优点普遍受到欢迎。例如生产效率高,制件质量好,节约原材料等等。但在推广使用中,也发现该工艺目前尚有须进一步完善之处,如对黑色
Cold extrusion process is a non-cutting new technology. In recent years, both at home and abroad attach great importance to this new technology and continue to expand its scope of use. From the daily hardware, electrical appliances to the car tractors, aerospace industry are extensive use of this new technology. The materials used also gradually transition from non-ferrous metals to ferrous metals, stainless steel, and even high-speed steel. This new process has been widely adopted due to its many obvious advantages during its rollout. For example, high production efficiency, quality parts, saving raw materials and so on. However, in the promotion and use, but also found that the process there are still some further improvements, such as black
