How to prevent the deformation of CNC spinning molds

Spinning is a method by which flat blanks or preforms can be processed to obtain thin-walled hollow rotating articles.

In the field of metal processing engineering, spinning is a new technology for chip-free forming of metal products. This molding technology has the advantages of good deformation conditions, good product performance, small dimensional tolerances, high material utilization, and a wide range of products. However, when the CNC spinning machine is processing, there will be mold deformation. Many people know very little 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 deformation of CNC spinning molds.

  • 1. The mold structure design of CNC spinning machine should be reasonable, the thickness should not be too large, and the shape should be symmetrical. For the large deformation CNC spinning machine mold, the deformation law should be mastered, and the machining allowance should be reserved. For large, precise and complex molds, it can be used. Composite structure.
  • 2. Reasonable selection of heating temperature and control of heating speed. For sophisticated and complex molds, balanced heating methods such as slow heating and preheating can be used to reduce heat treatment deformation of the mold.
  • 3. On the premise of ensuring the hardness of the CNC spinning machine mold, try to use pre-cooling, graded cooling quenching or constant temperature quenching process. For some complex molds, preheat treatment, aging heat treatment, tempering and nitriding heat treatment can be used to control the precision of CNC spinning machine molds.
  • 4. When repairing mold blisters, pores, wear and other defects as soon as possible, use repair equipment with less thermal shock such as cold welding machines to avoid deformation during the repair process.

Before production and processing, we must first make a preliminary plan for the overall work, arrange all aspects of the entire work properly, and have a good plan in the spinning process. This is the important thing in the spinning process. Very good guarantee.

There are certain safety hazards in any processing and production work. In the process of processing, the staff should pay attention to their own safety and comprehensively improve their safety awareness.
