CNC spinning machine is the processing equipment for CNC forming spinning?

In the field of metal processing engineering, spinning is a new technology for chipless forming of metal products. The molding technology has the advantages of good deformation conditions, good product performance, small dimensional tolerance, high material utilization rate, and wide product range. However, when the CNC spinning machine is processed, there will be deformation of the mold. Many people don't know much about it. In fact, as long as the deformation law is mastered, this deformation can be prevented. Let's take a look at how to prevent the mold. The problem of processing deformation.

1. The design of the mold structure of the CNC spinning machine should be reasonable, the thickness should not be too disparate, the shape should be symmetrical, and the deformation of the CNC spinning machine should master the deformation law and reserve the machining allowance. For large and sophisticated molds, the combination can be used. structure.

2. Reasonably select the heating temperature and control the heating speed. For the sophisticated molds, slow heating, preheating and other balanced heating methods can be adopted to reduce the heat treatment deformation of the mold.

3. Under the premise of ensuring the hardness of the CNC spinning machine, pre-cooling, grading cooling quenching or warm quenching process should be used. For some sophisticated molds, pre-heat treatment, aging heat treatment, quenching and tempering heat treatment can be used to control The precision of the CNC spinning machine mold.

4. When repairing defects such as sand holes, pores, and abrasions of the mold, use a cold welding machine and other small heat-repairing equipment to avoid deformation during the repair process.

In contemporary society, the economic development is expanding day by day, and many industries are becoming more and more mature. China is also very accomplished in this aspect of CNC lathes. When it comes to CNC, it has to be said that CNC spinning machine has played a considerable role in our work. Important role.

Simply put, the CNC spinning machine is the processing equipment for numerically controlled spinning. The purpose is to form thick-walled metal into a cylindrical part, including some insoluble metals, stainless steel and other materials, and then pressed into various sizes of thin-walled pipes or hollow rotating parts by a numerical control spinning machine. The pressing process means that the burrs are clamped on the model, and they are rotated by the CNC spinning machine together at high speed. At the same time, the pressure of the drum is utilized. The burrs are deformed and finally an axisymmetric part is obtained.

The pressing molds that we usually use are relatively simple, and local deformation, the function is the equipment and processing parts with small available power and tonnage, and is generally used in parts with small and complex shapes. The working principle of the CNC spinning machine is to use the high-speed rotation of the workpiece. The strong external force presses the workpiece according to a certain path. The roller will repeatedly press the material to make it from point to line, and the line to the surface will eventually lead to the workpiece. The deformation forms the shape we need. The selection of the CNC spinning machine is determined by the spinning process and various molding process conditions.
