Lubricant influencing mechanism is added to the friction interface near the entrance of the lubricant to the friction interface has three mechanisms: (1) by the hydrodynamic pressure into the principle is in the stamping process by the wedge effect into the lubricant or Bring lubricant into the film by the squeeze film effect.
(2) Recesses on the surface of the billet are brought into the surface of the lubricant processed material. Generally, there are tiny bumps. The lubricant accumulated in the recesses will not be overflowed when the mold and the billet contact with each other. Mechanically sealed in between, clamping friction interface, play a role in lubrication.
(3) Lubricant is brought into lubricant by adsorption. Physical and chemical adsorption can be performed on the metal surface to prevent flaking of the lubricating layer at the entrance of the friction surface, that is, to effectively bring in the lubricant.
Composition of water-soluble stamping lubricant According to the principle of stamping and performance requirements for lubricants, after a large number of tests, we selected the formulation of water-soluble stamping lubricants. It is made from animal and vegetable oils, base oils, oil additives, extreme pressure agents, antioxidants, surfactants, rust inhibitors, lubricating thickeners, defoamers, mildewproofing agents, and water, formulated according to process requirements.
In the process, quantitative animal and vegetable oils are slowly added to the heated triethanolamine, and the reaction is completed and placed. After dissolving T701 with kerosene, oil is added, and then the reaction product of animal and vegetable oil and triethanolamine is added and stirred, then a small amount of water is added, and other additives are slowly added under stirring. Finally, the water is added to the final amount and filled into the finished product.
