Abstract
The present invention relates to a heat treatment method for knife edges with tungsten carbide, which relates to a heat treatment method for knives. The present invention is used for solving the problems of multiple production link, long production time, high production cost, low knife rigidity, easy abrasion of knife edges, short service life, etc., which exist in the prior art. The present invention comprises: tungsten carbide is poured into one side of a knife edge with electricity, heat treatment is carried out for the knife, wherein the one-side rigidity of the knife edge is from HRc 65 to 85, and the case depth of the tungsten carbide in the knife-edge is from 0.01 millimeter to 0.04 millimeter. The present invention is mainly used for the technical field of optimizing the surface properties of metal components.
Description
Technical field
The present invention relates to a kind of metal heat treating methods, especially a kind of cutter heat-treating methods.
Background technology
Thermal treatment is the rule of utilizing the metal solid-state phase changes, and metal is varied with temperature, and weave construction takes place change, to improve and to control the technology-oriented discipline of physics, chemistry and the mechanical property of metal.Thermal treatment can divide three major types: general thermal treatment, thermo-chemical treatment and thermomechanical treatment.Thermo-chemical treatment is to utilize the diffusion in the metal and the formation rule of alloy phase, make metal in specific controlled medium, infiltrate different elements from the surface, change the chemical ingredients and the weave construction of matallic surface layer, and can in thermal treatment subsequently, make metal that required phase transformation takes place.Usually the unit of infiltrating have: carbon, nitrogen, boron, oxygen, sulphur, aluminium, chromium, silicon, vanadium, titanium etc., also can infiltrate multiple element simultaneously.Thermo-chemical treatment can be gaseous state, liquid state or solid-state carrying out.
It is different that the knife back face of general cutter and the metallic substance of knife-edge part are formed, and the hardness of knife back face is less than the hardness of knife-edge part, cutter after heat treatment, knife-edge part hardness is at HR
cAbout 50 degree.Because edge of a knife both sides hardness is identical, wear and tear simultaneously in the blade both sides in daily use, makes the easy rust of the edge of a knife.Report at the monolateral surfacing tungsten carbide material of cutter is abroad arranged recently, and wolfram varbide is the alloy material that a kind of wear resistance is good, hardness is high, uses this method can make the hardness of cutter reach HR
cAbout 65 degree; But this surfacing wolfram varbide arts demand adds other alloys, production link increases, the production time prolongs, production cost improves thereby make, and the hardness of cutter increases seldom, and tungsten carbide material is not enough in the blade surface degree of depth, not significant raising in the work-ing life of cutter.
Summary of the invention
The purpose of this invention is to provide a kind of heat treatment method for knife-edge tungsten carbide, in order to solve problems such as the production link that exists in the prior art is many, the production time is long, production cost is high, cutter hardness is low, the edge of a knife is easy to wear, work-ing life is short.
The object of the present invention is achieved like this: cutter edge of a knife single face electricity is annotated tungsten carbide material, cutter is heat-treated, wherein the hardness of edge of a knife single face is HR
c65 degree are to 85 degree, and tungsten carbide material is 0.01 millimeter to 0.04 millimeter at edge of a knife case depth.Because there is being differing about tens degree on edge of a knife both sides on the hardness, the cutter also difference of in use wearing and tearing because of edge of a knife both sides hardness is different can keep the blade sharpness permanent so like this, reaches the ideal result of use.
Compared with prior art, the present invention has following advantage:
1. production process automatization control reduces labor intensity, and enhances productivity;
2. the minimizing production link is shortened working hours, and reduces production costs;
3. cutter hardness height, the edge of a knife is wear-resistant, long service life.
Embodiment
Below in conjunction with embodiment, the present invention is explained in detail
Embodiment 1:
Cutter edge of a knife single face electricity is annotated tungsten carbide material, cutter is heat-treated, wherein the hardness of edge of a knife single face is HR
c65 degree, tungsten carbide material is 0.01 millimeter at edge of a knife case depth, can get product of the present invention.
Embodiment 2:
Cutter edge of a knife single face electricity is annotated tungsten carbide material, cutter is heat-treated, wherein the hardness of edge of a knife single face is HR
c80 degree, tungsten carbide material is 0.03 millimeter at edge of a knife case depth, can get product of the present invention.
Embodiment 3:
Cutter edge of a knife single face electricity is annotated tungsten carbide material, cutter is heat-treated, wherein the hardness of edge of a knife single face is HR
c85 degree, tungsten carbide material is 0.04 millimeter at edge of a knife case depth, can get product of the present invention.
