Spinning technology and the benefits of successful application of CNC metal forming equipment

The spinning forming process equipment is an automatic spinning machine. The thick-walled metal tubular parts, including refractory metal, non-ferrous metal, stainless steel, etc., are strongly spun into thin-walled pipes of various sizes or spun-shaped into a special-shaped hollow rotary part by an automatic spinning machine. Spin forming is to clamp the blank onto the core, and the automatic spinning machine drives the core and the blank to rotate at a high speed. At the same time, the roller pressure and the feed motion are used to locally deform the blank, and then the axisymmetric parts are obtained. The spinning mold is simple and local deformation, and the large parts can be processed with small power and tonnage equipment, and are used for small and complex shapes.

The principle of the automatic spinning machine is that when the workpiece rotates at a high speed, a strong external force presses the workpiece according to a certain path, and the roller repeatedly presses the material to make it from point to line, and the shape of the workpiece is caused by the thermal deformation of the workpiece from the line to the surface. Different pressing force is required. The small automatic spinning machine servo motor drives the screw to generate pressure. Some large powerful automatic spinning machines need hydraulic pressure to squeeze.

In the field of CNC metal forming equipment processing engineering, spinning is a new technology for chipless forming of metal products. Spinning processing utilizes metal ductility and combines the characteristics of forging, extrusion, drawing, bending, ring rolling, cross rolling and rolling to achieve a high quality and efficient metal forming process with no cutting. Strong spinning has developed rapidly since the 1950s. The molding technology has the advantages of good deformation conditions, good product performance, small dimensional tolerance, high material utilization rate, wide product range, and processable seamless hollow rotary body parts. It has been shown to be advanced, practical and economical in the industrial sectors of advanced industrial countries.

The successful application of spinning technology and CNC metal forming equipment has promoted the development of cutting-edge technologies such as aviation, rockets, missiles and satellites. In the industrial sectors such as conventional weapons, chemicals, metallurgy, machinery manufacturing, electronics and light industry and civilian use, it has become a large-scale Wide metal processing technology equipment and products. As a new technology and traditional process, spinning processing has developed into a new field of modern metal pressure processing.
