Method and its device for preparing cutter by laser coating composite ceramic layer

Abstract

The present invention relates to method and apparatus for making cutter with laser coated composite ceramic layer, belongs to the field of ceramic coating on metal surface, and aims at lowering cutter manufacturing cost while prolonging the service life of cutter. The cutter making process includes applying hard alloy powder to the surface of cutter base, applying mechanical pressure, preheating, and laser treating after or while applying the hard alloy powder. The cutter made may be chemical fiber cutter, milling cutter or trimming cutter. One of the cutter making apparatus includes bench, special fixture, electromagnetic coil and laser processing system. The other cutter making apparatus includes bench, chuck, powder blowing feeder and laser processing system. The present invention has high coating quality, less heat deformation, high production efficiency and other advantages.

Description

technical field

[0001] The invention belongs to the field of ceramic materials, in particular to the field of ceramic coatings on metal surfaces. Background technique

[0002] Ceramic materials have been widely used to make cermet knives at present, and the combination of ceramic materials and the knives (knife base) is usually connected by adhesive or by hot pressing or sintering. Chemical fiber cutting knives are cutting knives in the production of man-made fibers and synthetic fibers. The quality and cost of chemical fiber cutting directly affect the production efficiency of short fibers. At present, most domestic manufacturers of short fibers use Romus cutting knives. The Romus cutting knives are made of L135 hard alloy, sintered as a whole, and finally ground to shape. However, the cost of this tool is high and the price is relatively expensive. On the shaped hollow tool holder, each pay 56, because the tool blade wears fast, the tool consumption is large. Contents o...
