The use of appropriate lubricants has a significant effect on the deep drawing of stainless steel. The lubricant can form a film with a certain degree of toughness and elongation between the convex and concave dies, which is beneficial to the deep drawing of stainless steel.

　　For stainless steel deep-drawn parts with large drawing deformation and difficult forming, in actual production, a polyvinyl fluoride film can be used as a lubricant. Polyvinyl fluoride film has excellent tear strength, certain toughness and elongation, and is easy to clean. After coating the dry film, the dry film can be deformed with the blank during the deep drawing process, and the blank can always be separated from the mold. In addition, the film itself has a certain degree of porosity and a large number of fiber cracks, so a certain amount of lubricating oil can also be stored, so the film It is equivalent to a layer of dry film lubricant. This lubrication method can effectively isolate the deformed stainless steel plate from the surface of the mold, and has a good lubrication effect, which is beneficial to improve the service life of the mold and the pass rate of the product.

In addition, there are some other simple preventive measures such as using white cast iron as the edge holder abrasive tool, because the white cast iron has good oil storage performance, it is easy to form a lubricating oil film; another example is the use of a tapered edge holder; in addition, the workpiece edge is processed smoothly , Removal of micro-cracks can also effectively prevent cracking.
