摘要 旋压技术是一种综合了锻造、挤压、拉伸、弯曲、环轧、横轧和滚挤等工艺特点的少切削、无切削加工的先进技术。它是通过旋转使受力点由点到线由线到面，同时使金属材料沿着这一方向变形和流动而成型的技术Abstract Spinning technology is a comprehensive forging, extrusion, stretching, bending, ring rolling, cross rolling and get crowded the technical characteristics, such as cutting, no less of the cutting process of advanced technology. It is through the rotation to force a point by point to the line, again by line to the face, and at the same time makes the metal material along the direction of the flow and deformation and forming technology, also called metal spinning forming technology. This paper expounds the metal spinning forming technique in all major areas of application and development, detailed introduces the spinning process technology, typical the spinning technology solutions, spinning equipment and key device, typical spinning equipment. Mainly introduces the titanium alloy spinning technology research and application. This paper is mainly the theoretical study of the spinning forming process to solve problem, through the analysis can know, spinning technology in the modern industry got a lot of application, especially in aerospace business field.
