How to choose stamping oil in stamping process

Stamping oil is a metal processing oil prepared by adding vulcanized lard as the main agent and adding various additives such as refined oiliness agent and rust inhibitor. It is especially suitable for high-strength operations such as punching, stamping, tapping, and grooving. At the same time, it is also very suitable for plastic forming. It has good lubricity and extreme pressure, and has good protective properties for the mold. In the process of producing stamping parts, the use of stamping oil is essential. It not only provides good lubricity and cooling for the stamping process, but also helps to extend the service life of the equipment. So what are the requirements for the oil for stamping parts? First of all, of course, it must have good lubricity, otherwise it will cause adverse effects on the workpiece or material, not only the quality of the stamping parts is not high, but the service life of the stamping die will also be shortened. At the same time, it must have a certain degree of cooling. A lot of heat will be generated during the stamping process. If it cannot be emitted in time, it will easily cause deformation of the material. In order to effectively avoid rusting of the stamped parts after forming, the stamping oil used must be rust-proof, so that the oil film on the surface of the stamping parts can be protected from damage, so as to achieve a good rust-proof effect. In practical applications, the anti-rust effect is also affected by factors such as the nature of the stamping oil, processing conditions, and environmental factors, so the oil has higher requirements for anti-rust properties. In order to improve production efficiency while simplifying the process, the oil used in the stamping parts is required to have the effect of oil welding to prevent defects when the stamping parts are welded with oil. At the same time, degreasing is also one of the basic performance requirements of stamping, don't forget. In addition, since the oil is usually applied to the plate before the stamping part is processed, it must have a good control and can last for a period of time. On the one hand, other properties of the stamping oil are affected by the passage of time. Reduced by. According to the material to be stamped, the silicon steel plate is a material that is easier to punch. Most of them require that after punching, the attached oil film should be able to dry quickly. At the same time, it is necessary to prevent the generation of burrs on the punched products and prolong the life of the mold. Therefore, the viscosity of the selected stamping oil is as high as possible, the drying time is short, and the stamping oil with good rust resistance and carbon is not produced after annealing. In the stamping process, due to the different materials used, the stamping oil used will be different: Carbon steel: The stamping oil with the appropriate viscosity is mainly selected according to the difficulty of processing. Tin-plated steel: stamping oil without chlorine additives to prevent white rust. Aluminum and aluminum alloy: Punching oil with chlorine and sulfur additives cannot be used, and it is better to use punching oil with a neutral pH. Stainless steel plate: It is prone to work hardening. It is required to use lubricating oil with high oil film strength and good sintering resistance, and the lubricating oil must have high viscosity and good cooling. Copper and copper alloys: stamping oil containing sulfur and sulfur should not be used, and stamping oil with oily agents and good sliding properties should be selected.
