Abstract

Belonging to the technical field of metal processing, the invention particularly relates to a metal incremental forming lubricant and a preparation and use method thereof. Directed at the problems ofshort service life of forming heads, poor quality of prepared metal products and the like in the prior art, the invention provides a metal incremental forming lubricant, which comprises, by weight, 70-100 parts of titanium dioxide, 15-30 parts of molybdenum disulfide, 5-10 parts of graphite, 2-8 parts of organic silicon oil, 1-5 parts of lead iodate and 1000-1500 parts of mineral oil. The invention also provides a preparation method of the lubricant, and the raw materials are weighed by weight and then mixed evenly to obtain the product. The lubricant provided by the invention is simple in composition, and the raw materials are economical and environment-friendly. Through proper proportioning, the prepared lubricant realizes optimized distribution of the surface lubricating properties of forming heads, improves the plastic flow of formed materials, improves the service life of the forming heads and the product quality, and has wide application space.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a progressive metal forming lubricant and a preparation and use method thereof. Background technique [0002] During the progressive metal forming process, the deformed metal generates directional flow relative to the surface of the forming head during plastic deformation, thereby generating friction and friction force on the interface between the deformed body and the forming head, which causes bonding between the metals and greatly reduces the service life of the forming head . For incremental forming of sheet metal, the friction between the sheet metal and the surface of the forming head is usually in the state of "boundary friction", which is a very complex friction state with non-uniform distribution. Deformed metals are in a state of viscoplastic flow and new surfaces are constantly generated, resulting in harsh lubrication conditions and variable and ...
