Problems solved by technology

[0003] Knives are essential supplies commonly used in the kitchen for cutting vegetables, meat and fruits, but the existing kitchen knives are generally made of stainless steel, for example, 3Csr13 stainless steel is mainly used, and processed after the overall heat treatment, however , the hardness of the cutting edge of these existing tools after heat treatment is low, and the wear resistance is not ideal. In the prior art, in order to improve the hardness and wear resistance of the tool, laser cladding is used to form an alloy coating in the tool. layer, but the hardness and wear resistance, durable sharpness are still not the best

Embodiment 1

[0035] Alloy filling method of alloy powder set knife: make the knife body, the knife body has a knife body and a knife edge; use CNC to make grooves on the edge of one side of the knife edge, and use a laser beam to act on one side of the knife blank. There is a filling groove on the side, and the filling groove has an arc; the powder feeder is used to send the alloy powder to the filling groove. The inner diameter of the powder outlet of the nozzle of the powder feeder is 1.1mm, the inner diameter of the restraint auxiliary gas pipe is 5mm, and the inner diameter of the outermost protective gas pipe is 5mm. It is 9mm, the carrier gas of the alloy powder, the nozzle powder beam gathering gas and the outer protective gas are all helium gas, the protective gas flow rate is 14L / min, and the nozzle angle is 40 degrees. The effect of restraining the powder beam makes the nozzle powder have a good restraint length and necessary stiffness when it is ejected. Laser cladding is carried...

Abstract

The alloy powder sleeve cutter comprises a cutter body, the cutter body comprises a cutter body, a cutting edge and a filling groove, the cutting edge is arranged at the edge of the cutter body, the filling groove is formed in the cutting edge, the appearance of the filling groove has a radian, and the filling groove is filled with alloy powder. The preparation method is simple, the process conditions are loose, implementation is easy, the alloy powder layer is sprayed and welded through laser cladding, one side of the cutting edge part is filled with alloy powder, the other side of the cutting edge part is the base material, and the hardness and wear resistance of the alloy powder layer are higher than those of the base material, so that when the kitchen cutter is frequently used, the cutting edge part is not damaged at the cutting edge position; the base material layer can be abraded during cutting, the alloy powder layer cannot be abraded, the base material layer can be thinned by grinding, the cutting edge is sharper and sharper under the condition of long-term use, the cutter is good in lasting sharpness, alloy powder is dispersed uniformly, the longitudinal and transverse uniformity of the internal organization structure of a product is guaranteed, and the abrasion resistance is improved.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to an alloy powder knife set and an alloy filling method thereof. Background technique [0002] A metal powder formed by partial or complete alloying of two or more components. Alloy powders are classified into iron alloy powder, copper alloy powder, nickel alloy powder, cobalt alloy powder, aluminum alloy powder, titanium alloy powder and precious metal alloy powder, etc. Cemented carbide consists of a hard matrix and a bonding metal. Cemented carbide is an excellent tool material, mainly used for cutting tools, metal forming tools, surface wear-resistant materials and high-rigidity structural parts. The hard matrix is ​​made of refractory metal compounds, mainly tungsten carbide and titanium carbide, as well as tantalum carbide, niobium carbide and vanadium carbide, etc., to ensure that the alloy has high hardness and wear resistance. The iron group metals and their alloy...
