The role and use requirements of lubricating oil in the production of drawing parts

Metal stretched parts are a kind of metal products that are widely used. We can often see them in our lives. For example, some cups and basins are made of stretched metal. Stamping and drawing processing plants need to use lubricating oil when performing drawing processing. So what is the role of lubricating oil in the stretching process? Next, Precision will give you a specific introduction. The role of lubricating oil in the metal stretching process is as follows: 1) Reduce the friction between the raw material and the mold, thereby effectively reducing the stretching force. It has been verified that the use of lubricant can reduce the tensile force by about 30% compared with no lubricant. 2) The use of lubricants can achieve one-time large deformation during the deep drawing process, thereby reducing the number of stretching passes. The stretched part that has been stretched is also easier to take out from the mold. 3) The lubricant can protect the surface of the drawing die and cool the die, thereby improving the life of the die; the lubricant also has a protective effect on the surface of the drawing part, which can ensure the quality of the metal drawing part.
