Micro-texture surface coating self-lubricating cross-shear cutter embedded with solid lubricants

Abstract

The invention discloses a micro-texture surface coating self-lubricating cross-shear cutter embedded with solid lubricants. The micro-texture surface coating self-lubricating cross-shear cutter comprises a cutter body, a plurality of grooves are formed in a contact surface of the cutter body which is in contact with a metal plate, and the grooves are filled with the solid lubricants. A lubricatingcoating is disposed on the contact surface of the cutter body which is in contact with the metal plate, and the lubricating coating covers the solid lubricants filling the grooves. When the lubricating coating is run out, the solid lubricants are released to lubricate the contact surface between the metal plate and the cutter body, so that the lubrication time is greatly increased and the duration and stability of lubrication are ensured. Since the solid lubricants are softened and released by the high temperature action generated during processing, the lubricating effect of the solid lubricants is poor when the cutter body shears at a low speed; and according to the micro-texture surface coating self-lubricating cross-shear cutter embedded with the solid lubricants, the lubricating lubricants are covered with the lubricating coating, so that the cutter body is better lubricated during low-speed shearing, and the range of application of the cutter body is enlarged and the performanceof the cutter body is improved.

Description

technical field [0001] The invention relates to a self-lubricating horizontal scissors, in particular to a self-lubricating horizontal scissors with a micro-textured surface coating embedded with a solid lubricant. Background technique [0002] The shearing of metal sheets mainly includes two processing methods: longitudinal shearing with disc shears and transverse shearing with oblique blades. The material is cut into a flat sheet of the required length for subsequent processing. [0003] Horizontal scissors are used for fixed-length cross-cut processing of plates. At present, the common way of knife grouping generally adopts inclined blade cross cutting, usually the lower knife is fixed, and the upper knife moves up and down to cut off the plate in the middle. Due to the existence of the inclined blade angle, the upper cutter cuts into the plate step by step, which can effectively reduce the shearing force and improve the quality of the shearing section.
