Description
Technical field
The utility model is related to a kind of knife, more particularly to a kind of superhard alloy knife.
Background technology
The hardness of cutter material has very big influence to the sharpness performance of cutter, cutter product currently on the market
Hardness all only has HRC48-56 degree according to material difference, and the product of more high rigidity only has high end materials can be up to or over
HRC60 degree, and the product of these high end materials production is used, cost is also the increase in geometry, causes wave in a way
Take.
Utility model content
For in the prior art the defects of, the purpose of this utility model is to provide a kind of superhard alloy knife, reduce into
This, reduces waste, improves sharpness.
One side according to the present utility model provides a kind of superhard alloy knife, which is characterized in that including：
Hilt；
Blade is connected with one end of hilt, and including the edge of a knife, hilt fixing port, hilt fixing port is located at the one side of the edge of a knife；
Blade positioned at blade bottom, is closed including stainless steel layer, hard alloy layer, trapezoid-shaped openings, the tooth punching edge of a knife, hard
Golden cutting edge, stainless steel layer are located at the one side of hard alloy layer, hard alloy layer between trapezoid-shaped openings and hard alloy cutting edge,
The tooth punching edge of a knife is located between two adjacent hard alloy cutting edges.
Preferably, the shape of the tooth punching edge of a knife is waveform.
Compared with prior art, the utility model has following advantageous effect：The utility model is simple in structure, reduces into
This, reduces waste, improves sharpness, is used conveniently and safely, hardness is big.
Description of the drawings
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other spies of the utility model
Sign, objects and advantages will become more apparent upon：
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the partial enlarged view at the B of Fig. 1.
Fig. 3 is the sectional view along the A-A directions of Fig. 1.

Specific embodiment
The utility model is described in detail with reference to specific embodiment.Following embodiment will be helpful to this field
Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made.
These belong to the scope of protection of the utility model.
As shown in Figures 1 to 4, the utility model superhard alloy knife includes：
Hilt 4；
Blade 14 is connected with one end of hilt 4, and including the edge of a knife 1, hilt fixing port 3, hilt fixing port 3 is located at the edge of a knife 1
One side；
Blade 2, positioned at 14 bottom of blade, including stainless steel layer 5, hard alloy layer 6, trapezoid-shaped openings 7, the tooth punching edge of a knife 8,
Hard alloy cutting edge 9, stainless steel layer 5 are located at the one side of hard alloy layer 6, and hard alloy layer 6 is located at trapezoid-shaped openings 7 and hard closes
Between golden cutting edge 9, the tooth punching edge of a knife 8 is located between two adjacent hard alloy cutting edges 9.
The shape of the tooth punching edge of a knife 8 is waveform so that it is convenient to cut.
The hilt fixing port 3 is non-dismountable so that it is convenient to clean and not easily to fall off.
The operation principle of the utility model is as follows：For the edge of a knife for cutting thing, blade is harder for cutting some
Thing, for hilt fixing port for fixing cutter preventing hilt from coming off, hilt takes knife easy to use for hand.Blade is locally using hard
Matter alloy-layer so has the function of that sharp and hardness is big, while has the tooth punching edge of a knife, equally also has sharp function, so
The utility model is simple in structure, reduces cost, reduces waste, improves sharpness, is used conveniently and safely, hardness is big.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
This has no effect on the substantive content of the utility model.
