Abstract
Description
technical field
[0001] This invention relates to water washable stamping and drawing oils. Background technique
[0002] Metal processing includes cutting and stamping stretching, etc. Compared with cutting, stretched products have better mechanical properties, so stamping stretching is often used on some metal products with high load requirements, such as body stamping, pipe bending , diameter expansion, oil pan stretching, etc., and the stamping and stretching process has the characteristics of one-time forming, fast speed, and high efficiency. In the process of heavy-duty stamping and drawing, medium-high viscosity lubricating medium is required to isolate the mold and workpiece, prevent the mold from being damaged, and improve the success rate of workpiece drawing. The current heavy-duty stamping and drawing oil is mostly made of mineral-based base oil, added with extreme pressure anti-wear agents such as chlorine-based, sulfur-based, and phosphorus-based, and supplemen...
