The so-called stamping and drawing oil refers to the lubricating oil used in the stamping and drawing process. Stamping is a forming and processing method that applies external force to sheets, strips, pipes and profiles by means of presses and dies to cause plastic deformation or separation to obtain workpieces (stampings) of desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively called forging. The stamped blanks are mainly hot-rolled and cold-rolled steel sheets and strips.
60-70% of the world's steel products are sheets, most of which are stamped into finished products. The body, chassis, fuel tank, radiator sheet of the car, the steam drum of the boiler, the shell of the container, the iron core silicon steel sheet of the motor and electrical appliances, etc. are all stamped. There are also a large number of stamping parts in instruments, household appliances, bicycles, office machinery, living utensils and other products. Platen forming oil It is suitable for the forming of thin plate parts of automobiles and motorcycles, as well as the deep drawing and calendering of stainless steel parts. With the characteristics of high strength and high adhesion, the single-type stamping and forming operation can better exert the surface finish and drawing of the workpiece. Stretching effect, desirability and essential oil for difficult mechanical stamping processing. Punching and shearing oil It is suitable for punching, punching, stretching, calendering and bending of various metal materials with thin thickness, especially for punching and shearing electrolytic sheets, silicon steel sheets, carbon steel and other materials that are prone to rust. The following conditions must be met: fast volatility (especially under heating conditions), the surface of the workpiece is dry, no cleaning is required, excellent extreme pressure lubricity, prolong the service life of the mold, ensure good processing quality of the workpiece surface, and have anti-rust function. Can be used for short-term storage, high flash point, low odor, low viscosity, good cooling, harmless to human body and environment. Precision stamping oil Precision stamping oil is a special lubricating oil for the stamping of aluminum fins of air conditioners and evaporators, as well as copper tube expansion and bending. The production process has extremely high requirements on its lubricity, safety and volatility. The product has suitable lubricity and low temperature performance, which can improve the stamping quality of the workpiece, effectively protect the mold, no residue, non-toxic and tasteless, harmless to the human body, and non-corrosive to non-ferrous metals such as copper and aluminum. Classification of stamping and drawing oil: 1. Stamping and drawing oil can be divided into: Stainless steel stamping and stretching oil, iron stamping and stretching oil, aluminum alloy stamping and stretching oil, galvanized sheet stamping and stretching oil, cold-rolled sheet stamping and stretching oil, stainless iron stamping and stretching oil, etc. 2. According to the degree of volatility: non-volatile, semi-volatile, volatile 3. According to whether to add water or not, it is divided into oil-based stamping and stretching oil and water-based stamping and stretching oil In order to make more customers familiar with how to choose stamping and drawing oil, I will share the selection principles of stamping and drawing oil here. 1. What material to process: stainless steel, carbon steel, aluminum alloy, copper alloy, etc. 2. Processing strength: stamping or stretching, or both. 3. Whether the oil has anti-rust requirements. 1) Product requirements for the stamping of silicon steel sheets: 1. No cleaning (volatile oil); 2. Lubrication and rust prevention. Recommended products: volatile punching and shearing oil, volatilization time of ten minutes, characteristics: low viscosity, fast volatilization, no residue. 2) Product requirements for stamping of digital product terminal supports: 1. Anti-rust; 2. No-cleaning (volatile); 3. Lubrication. Recommended products: medium volatile punching and shearing oil, volatilization time between half an hour, characteristics: low viscosity, excellent extreme pressure lubricity, no residue and no cleaning. 3) Product requirements for stamping and forming of parts: 1. High lubrication; 2. High rust prevention (more than 1 week); 3. Some customers require oil to match other chemicals; 4. Moderate viscosity Recommended product: stamping oil, viscosity: 70-80, characteristics: moderate viscosity, strong adhesion, suitable for medium difficulty stamping and stretching 4) Product requirements for dishwashing dishes and stainless steel molding: 1. High lubrication; 2. High rust resistance (carbon steel); 3. Easy to clean; 4. Low odor and environmental protection. Recommended products: stamping oil, viscosity 30-45, features: easy to clean, and has good extreme pressure lubrication performance, effectively preventing strain.
