In recent years, many research institutes have done a lot of research on the combination of heat treatment and spinning. Although the above research has provided theoretical support and practical guidance for the application of CNC spinning The development of production, in order to meet demand, the combined development of spinning technology and heat treatment will have epoch-making significance. With the development of science and technology, the requirements for spinning equipment products are getting higher and higher. Due to the work hardening and other defects in the cold spinning process, the cold spinning technology can no longer meet the needs of production. Appropriate heat treatment can refine the internal grains of the metal, change the crystal phase structure of the metal, and thus change the properties of the metal. Therefore, people began to combine heat treatment technology with spinning technology to create new spinning processing methods, laying a foundation for spinning technology New milestone.
The forming technology of metal spinning processing equipment is a kind of blank that is driven by the main shaft to rotate and fixed by the core mold and the top block, and then is fed axially and radially by the rotating wheel. The extrusion of the core mold and the rotating wheel makes the blank locally continuous. The plastic forming process of sexual deformation. Spinning forming technology is a combination of rotary forming and plastic forming. The advantages of both make it have the advantages of high material utilization, fast forming, good surface quality, high precision, and diverse products. Therefore, it not only occupies an important position in the fields of aviation, aerospace, weapons and other metal precision processing technology, but also has been widely used in the fields of petrochemical, automobile manufacturing, electronics and light industry.
The application of spinning technology is more and more extensive, and the requirements for spinning machine tools are getting higher and higher, especially spinning equipment with large turning diameter, large thrust, high precision and high degree of automation. Foreign powerful spinning equipment has been serialized and is constantly developing in the direction of large-scale, multi-purpose and high degree of automation. With the development of computer technology, the spinning machine tool control system has also been continuously developed. The rotary wheel feed is fully developed to numerical control, and the spindle speed change is developed from stepless to stepless, and developed to the multi-wheel rotary turret spinning machine. The TV monitoring system and the ultrasonic automatic measuring device for wall thickness required for processing large-diameter parts have also been applied on the spinning machine tool.
