Abstract

The invention discloses a lubricating agent composition for white alloy cold drawing machining. A compound of HVIH14 and methyl palmitate is adopted as basic oil and cooperates with various composite additives. The lubricating agent composition includes antioxidant, a metal passivator, an oiliness agent, antiwear agent, an extreme pressure agent, a friction improver, a viscosity index improver, a filling agent, antirust agent and others. The composition has the advantages that the number of machined workpieces and molds needing to be rubbed, lubricated and cooled is reduced, power consumption is lowered, and deformation is uniform; the service life of a tool is prolonged, and abrasion of workpiece materials is controlled; the quality of the surface of machined metal is improved, and the tolerance of the surface of the machined metal is reduced; temperature is controlled, and machining deformation is reduced; new and old surfaces of the machined metal are kept oxidized or passivated; using is safe, and toxins do not exist; residues do not affect machining and operating, and cleaning is convenient.

Description

technical field [0001] The invention belongs to the field of metal processing lubricants, in particular to a composition of a white metal cold drawing processing lubricant. Background technique [0002] White metal was named after the invention of American Babbitt, because of its white color, it is also called Babbitt alloy. Including tin-based bearing alloys and lead-based bearing alloys, are widely used. It has anti-friction properties and is the only material suitable for rotating relative to a low-hardness shaft. Compared with other bearing materials, it has better adaptability and press-fit properties. It is widely used in large marine diesel engines, turbines, alternators, and Other mining machinery and large rotating machinery, etc. Its main alloy components are tin, lead, antimony and copper. Antimony, copper, used to increase the strength and hardness of the alloy. [0003] The microstructure of Babbitt alloy is that hard phase particles are evenly distributed o...
