The conical surface of the bevel-type head of a nail matches.
Disposable cutting blade described in the utility model, the cutter hub slope surface and blade slope surface mutually seamlessly transit.
The gradient of Disposable cutting blade described in the utility model, the cutter hub slope surface and blade slope surface is 30-45 degree.
Disposable cutting blade described in the utility model, the general thickness of the blade are 3.5-8.5mm, the thickness of the blade
Degree is 1-3mm.
Disposable cutting blade described in the utility model, the cutter hub and blade, which pass through, to be welded and fixed, and in cutter hub lower surface
Welding layer is formed between blade upper surface.
After Disposable cutting blade described in the utility model, the blade and cutter hub are welded and fixed, then carry out whole polishing.
Disposable cutting blade described in the utility model, it is corresponding between the cutter hub and blade to be provided with fixed tooth and fixation
Hole, to enhance switching performance.
Disposable cutting blade described in the utility model, the blade are cemented carbide material production, and cutter hub is with high-ductility
Property ordinary steel production.
The utility model has the following beneficial effects: compared with prior art, it can be when blade cracks because of external force, blade tipping
In the case of only crumble a sword, and can still be continued to use by other swords after rotation angle, and due to be by hard alloy with
Steel part matrix is welded, and in tipping, fracture, fragment is firmly clung by cutter hub, will not splashes will not more damage pedestal,
The production cost of Scale of Wood Processing Enterprise is effectively reduced, and reduces the occurrence probability of industrial accident.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model technology.It should be appreciated that specific embodiment described herein is only used to
It explains the utility model, is not used to limit the utility model.
Embodiment 1:
As shown, Disposable cutting blade, blade includes cutter hub 1 and blade 2, and cutter hub 1 and blade 2 are separately formed
Rectangular frustum structure, the cutter hub 1 include cutter hub upper surface 11, cutter hub lower surface 12 and cutter hub slope surface 13, and the blade 2 includes
Blade upper surface 21, blade lower surface 22 and blade slope surface 23, cutter hub lower surface 12 and 21 secure bond of blade upper surface are one
It rises.The blade 2 is cemented carbide material production, and the material of cutter hub 1 can use general common iron, and have high tenacity
The characteristics of.Fixed form between the cutter hub 1 and blade 2 is to be welded and fixed, and in cutter hub lower surface 12 and blade upper surface
Welding layer 3 is formed between 21.Using above-mentioned composite structure, major advantage is can be when blade 2 be because of external force cracking, knife
2 tipping of sword only crumbles the sword of side, and still can continue to use and work by the sword in other directions after rotation angle, and by
Then it is welded by the cutter hub of hard alloy and ordinary steel, in tipping, fracture, the fragment of hard alloy can be by high tenacity
Cutter hub is firmly clung, will not splashes will not more damage pedestal, reduce the production cost of Scale of Wood Processing Enterprise, reduce industrial injury thing
Therefore occurrence probability.
After the blade 2 is welded and fixed with cutter hub 1, then carry out whole polishing.Make it have better overall appearance and property
Energy.
The cutter hub 1 and blade 2 are respectively equipped with the desk-top cutter hub mounting hole 14 and blade mounting hole 24 of circular cone, the cutter hub
The mutual smooth excessiveness of circular conical surface 15 and circular conical surface 25 of mounting hole 14 and blade mounting hole 24, can follow closely with the circular cone type of fixing screws
The conical surface of cap matches.It in this way can be easier and firm when fixed blade.
The cutter hub slope surface 13 and blade slope surface 23 mutually seamlessly transit；The slope of the cutter hub slope surface 13 and blade slope surface 23
Degree is 30-45 degree；The general thickness of the blade be 3.5-8.5mm, wherein blade 2 with a thickness of 1-3mm.Compared to traditional
Blade structure reduces the dosage of hard alloy, can substantially reduce use cost.
It is corresponding between the cutter hub 1 and blade 2 to be provided with fixed tooth and fixation hole (being to show in figure), knife can be prevented
Mutually rotation occurs after body 1 and blade 2 are fixed.The purpose of this design is, when welding, can increase welding material
With the contact area between cutter hub 1 and blade 2, and welding material solidification after formd between cutter hub 1 and blade 2 it is lenticular
Contact surface so that be connected with each other it is stronger and stablize, further make blade 2 tipping, fracture when, strengthen to broken
The effect of contraction of piece avoids dispersing everywhere, reduces the danger of site operation personnel.
In general, the overall dimensions of blade are smaller, exist in Grinding Process and do not allow the problems such as being fixed easily,
Difficulty is brought to relevant operation.Traditional blade is integrally hard alloy material, and magnetic conductivity is very poor, and the utility model
Described in by the compound Disposable cutting blade that is welded, although 2 part of blade of hard alloy is not easy magnetic conduction, as knife
The common iron of body 1 but has good magnetic property, can be criticized during the manufacturing using the grinding machine with disk
Grinding is measured, the production efficiency of enterprise is greatly improved, reduces manufacturing cost.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
