Abstract
The utility model discloses a kind of wear-resistance alloy knife material structure, including handle of a knife and blade, the blade includes S-shaped cutting edge and radiused cutting edge, the blade has 4 identical cutting edges on a piece of blade, there are two blades to simultaneously participate in cutting during Milling Process, indexing use can be achieved when blade is rotated 180 ° by blade after being worn out.
Description
Technical field
The utility model belongs to cutting-tool engineering field, more specifically, more particularly to a kind of wear-resistance alloy knife material structure.
Background technology
Ball end mill is mainly used in the machining of mould etc..The cutting edge of the front of the ball end mill is in side view
It is in arc-shaped during observation.In general, the bulb sword of the front is also in arc-shaped when from front end, and it is curvature
Radius shape constant from inner peripheral portion to peripheral part.
Application of the complex free curved surface in modern mechanical product is very extensive, such as body of a motor car housing, die workpiece table
Face, various pump class blades etc., the selection of its processing method and instrument, have material impact to the performance of final products；With
The popularization of Digit Control Machine Tool and the continuous improvement of Computerized Numerical Control processing technology, using ball end mill on 5-shaft linkage numerical control lathe energy
Enough processing and manufacturings for completing such part well.
How a kind of function admirable is designed, and wear-resisting alloy knife material is to need urgent problem now.
Utility model content
The purpose of this utility model is and a kind of wear-resistance alloy knife proposed in order to solve shortcoming present in prior art
Material structure.
To achieve the above object, the utility model provides following technical scheme：
A kind of wear-resistance alloy knife material structure, including handle of a knife and blade, the blade includes S-shaped cutting edge and circular arc is cut
Sword, the blade have 4 identical cutting edges on a piece of blade, have two blades to simultaneously participate in cutting during Milling Process, when
Blade is rotated 180 ° after being worn out and indexing use can be achieved by blade.
Preferably, the blade-shaped curve of the S shapes cutting edge is formed by orthogonal screw face and sphere are intersecting.
Preferably, the radiused cutting edge is due to the limitation of blade thickness itself, as S shape cutting edges in sphere
On rounded transitional sword.
Preferably, the orthogonal screw face just refers to that bus is straight line, and remains mutual with axis during bus rotation
Vertically, the helicoid formed.
Technique effect of the present utility model and advantage：A kind of wear-resistance alloy knife material structure provided by the utility model, with biography
System technology is compared, and it is dilute to add chromium, molybdenum, vanadium, silicon, manganese, carbon, tungsten, rhenium and nickel etc. using iron as primary raw material in iron for the utility model
There is element, the temperature of non-ferrous metal is smelted under 1600-1750 degrees Celsius, the alloy material of natural cooling shaping, is had
The features such as hard, toughness is big, sharpens a knife on a whetstone and feels very soft, and Rockwell hardness 58-60 toughness is high；It is additionally, since orthogonal spiral shell
The helical angle of spin line tooth shape is from 0 ° to maximum value changes, thus overcomes equal helix angle curve and can not reach at the top of blade
Defect, therefore be widely used in practice.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with specific embodiment,
The utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.Based on the embodiment in the utility model, those of ordinary skill in the art exist
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of the utility model protection.
Embodiment 1
As Figure 1-4, the utility model provides a kind of wear-resistance alloy knife material structure, including handle of a knife 1 and blade 2, described
Blade 2 includes S-shaped cutting edge 3 and radiused cutting edge 4, and the blade 2 has 4 identical cutting edges, milling on a piece of blade
There are two blades 2 to simultaneously participate in cutting when cutting processing, indexing use can be achieved when blade is rotated 180 ° by blade 2 after being worn out,
The blade-shaped curve of the S shapes cutting edge 3 is formed by orthogonal screw face and sphere are intersecting, the radiused cutting edge 4 be by
In the limitation of blade thickness itself, as rounded transitional sword of the S shapes cutting edge 3 on sphere, the orthogonal screw face just refers to
Bus is straight line, and remains the helicoid for being mutually perpendicular to, being formed with axis during bus rotation.
A kind of wear-resistance alloy knife material structure provided by the utility model, compared with conventional art, the utility model using iron as
Primary raw material, rare element, the temperature of non-ferrous metal such as addition chromium, molybdenum, vanadium, silicon, manganese, carbon, tungsten, rhenium and nickel exist in iron
Smelted under 1600-1750 degrees Celsius, natural cooling shaping alloy material, have it is hard, toughness is big, on whetstone
The features such as sharpening feels very soft, and Rockwell hardness 58-60 toughness is high；The helical angle for being additionally, since normal helix tooth shape is from 0 °
To maximum value changes, thus the defects of equal helix angle curve can not be reached at the top of blade is overcome, therefore obtained in practice
It is widely applied.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Progress equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc.,
It should be included within the scope of protection of the utility model.
