Abstract

The invention discloses a tungsten carbide coating cutter and a preparation technology thereof. The tungsten carbide coating cutter comprises a blade; a cutting edge is formed in the blade; the cutting edge is coated with a tungsten carbide coating; the blade is made of a titanium-cobalt alloy steel material; the surface of the cutting edge is completely coated with a tungsten carbide medium; andcomprehensive spot welding is conducted under spot welding equipment. According to the tungsten carbide coating cutter and the preparation technology, titanium-cobalt alloy steel is used as materialsof the blade and the cutting edge, combination of the tungsten carbide medium and the cutting edge is achieved in a spot welding mode, operation is easy, the requirement for the equipment is not high,the tungsten carbide coating is formed on the surface of the cutting edge, the strength and the abrasion resistance of the cutter can be greatly improved, and the service life of the cutter can be prolonged by five times or above; the titanium element and the cobalt element in the material of the cutting edge can be combined with tungsten carbide, the fragile characteristic of tungsten carbide can be overcome, the brittleness of the tungsten carbide coating can be reduced, the tungsten carbide coating is not prone to falling off, and compared with a common tungsten carbide coating, the cutterhas the advantages that the service life can be greatly prolonged, and the stability can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of grinder cutters, and in particular relates to a tungsten carbide coated cutter and a preparation process thereof. Background technique [0002] Knives need to be installed in the rear pulverizer. The knives generally include blades, blades and fixing holes for crushing materials. These knives generally have a certain service life, because the process of crushing materials will cause their own damage. Wear and tear leads to passivation of the blade, which affects the crushing efficiency and crushing effect of the post-shredder, and also increases the frequency of replacement and increases the cost of use. [0003] In the prior art, the hardness and wear resistance of the tool can be enhanced by adding a coating. There are two commonly used coating methods in production: physical vapor deposition (PVD) and chemical vapor deposition (CVD). The deposition temperature of the former is 500°C, and the coating t...
