Abstract

The invention discloses a method for preparing lubricating oil for stamping and deep drawing of sheets and relates to the technical field of stamping processing. The lubricating oil is prepared from the following raw materials in parts by weight: 40-50 parts of palm oil, 25-35 parts of castor oil, 0.3-0.5 part of antioxidant, 0.5-1 part of anti-wear agent, 0.5-1 part of anti-rust agent, 3-5 parts of extreme pressure agent and 2-3 parts of defoaming agent. The method comprises the following steps: respectively weighting the raw materials in parts by weight; placing palm oil and castor oil into a container, stirring while heating, when the temperature is raised to 80 DEG C, maintaining the temperature, and stirring for 20-25 minutes; continuously heating to 125 DEG C-130 DEG C, adding the residual materials, uniformly stirring and cooling to obtain the desired lubricating oil. The lubricating oil prepared by the invention has the advantages of large adsorption force, low cost and environmental friendliness; a continuous and uniform oil film is easily formed on the surface of a workpiece and the film is not easy break, overall lubricating properties are good, and the surface quality of the workpiece can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of stamping processing, in particular to a lubricating oil for sheet stamping processing. Background technique [0002] In the sheet metal stamping process, the stamping die exerts pressure on the metal sheet to produce plastic shear deformation, and the friction and impact force of the stamping abrasive on the sheet will increase the temperature of the deformed part, making it difficult to achieve the desired shape, and the dry friction state is easy To scratch the surface of the stamping workpiece, in order to avoid the above problems, lubricating oil is usually used for lubrication. The base oil of traditional stamping lubricating oil is mostly mineral oil, which is expensive to use and not environmentally friendly. This kind of lubricating oil is prone to uneven and discontinuous oil volume during the use of thin plate stamping and deep drawing production, resulting in some Insufficient lubrication on t...
