Description
Technical field
The utility model is related to saw blade to cut field, espespecially a kind of saw blade.
Background technology
Saw blade is widely used for cutting timber, artificial board, stone material, metal and the various materials such as nonmetallic.It is existing hard
Matter alloy saw blade generally includes saw blade support substrate and the cutter head by Welding on the toothholder at saw blade support substrate edge.
Superhard material of the cutter head generally by Hardmetal materials and based on hard alloy is made.The cutter head width of conventional blade and and
The consistency of thickness of saw bit matrix, but if in view of the rigidity of saw blade support substrate, the thicker saw blade of selection cutter head, because cutter head
Cutting material is that the material part that will be contacted is crushed, and so as to material is broken into two sections, so will result in the waste of material, and is selected
The less blade of thickness is selected, the Stiffness of whole saw blade easily causes the damage of saw blade.
Utility model content
The purpose of this utility model is the defect for overcoming prior art, there is provided a kind of support substrate center thickness is more than side
The saw blade of edge thickness, can both protect the rigidity of saw blade itself, and the waste of material is reduced again.
To achieve these goals, the utility model provides a kind of saw blade, including：
Matrix of the edge thickness less than center thickness；It is connected to the cutter head at the edge of described matrix, the thickness of the cutter head
It is adapted with the edge thickness of described matrix.
The beneficial effects of the utility model are：The thickness of matrix center is kept by reducing matrix border thickness not
Become so that saw blade ensure stiffness by itself while, be connected with matrix border cutter head thickness reduction so that reduce with it is to be cut
The contact area of material, reduces the loss of material.
Further improvement of the utility model is that described matrix is circle, and the thickness of described matrix is in radially
Stepped reduction.The center thickness of matrix is maximum, to the segment distance of edge extended spot one after, thickness is smaller, ladder decline it is multiple, directly
To the thickness for forming needs.
Further improvement of the utility model is that described matrix is circle, and the thickness of described matrix is in radially
Linearly it is gradually reduced.The center thickness of matrix is maximum, and then along the extrorse direction in center, the thickness of matrix is gradually smaller,
The similar top-type of shape of whole matrix.
Further improvement of the utility model is that described matrix is provided with radiating groove, and the radiating groove is circle, is passed through
One joint-cutting is connected to the bottom of the cutter head.The effect of radiating groove is rubbed in working angles, easily heating, will expand change
Shape, opens a sulculus and makes up the near of it and stretch rate, and deformation is reduced to the full extent.And radiating groove can play reduction noise, suppression
Make the effect of vibrations.
Further improvement of the utility model is, the radiating groove is multiple, in being uniformly distributed in described matrix.
Further improvement of the utility model is that the center of described matrix is additionally provided with a coupling hole.For saw blade
With the connection of actuating unit.
Further improvement of the utility model is that the edge shape of the sawtooth of the cutter head is arc-shaped.
Further improvement of the utility model is that the cutter head is fixed on the edge of described matrix by soldering.

Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described in further detail.
The utility model provides a kind of saw blade.Conventional blade is in order to ensure the rigidity of itself, and the thickness of its matrix is larger,
And the thickness of matched cutter head is also thicker, and cutter head is to make material damage by cutting material and bring it about fracture,
The larger cutter head of thickness increases the consume of material；And according to the less matrix of thickness, then the rigidity of saw blade cannot be ensured.
Now using an edge thickness relative to the matrix that center thickness reduces, the thickness of matrix border reduces, matched cutter head
Thickness also accordingly reduce so that the consume of material reduces, while center thickness is larger, also ensure that the rigidity of saw blade.Below
The structure of saw blade of the present utility model is illustrated with reference to accompanying drawing.
Refering to Fig. 1, the utility model saw blade includes：Matrix 1 and cutter head 2.Wherein the thickness at the edge of matrix 1 is less than matrix
The thickness at center, cutter head 2 is fixedly connected with the edge of matrix 1, and the thickness of cutter head 2 is adapted with the thickness at the edge of matrix 1.
As shown in Figure 1, 2, 3, as preferred embodiment of the present utility model, matrix 1 is circle, the thickness edge of matrix 1
Its radial direction reduces in stepped.A diameter of 305mm of saw blade of the present utility model, is classified as three boss, matrix
The first a diameter of 110mm of rank boss residing for center, thickness is 1.8mm, a diameter of 180mm of second-order boss, and thickness is
1.45mm, remainder is the 3rd rank boss, and thickness is 1.2mm, and the cutter head thickness being connected with the edge of matrix 1 is 1.2mm.
As shown in Figure 4,5, 6, as preferred embodiment of the present utility model two, matrix 1 is circle, the thickness edge of matrix 1
Its radial direction linearly to be gradually reduced.The thickness at matrix center of the present utility model is 1.8mm, the thickness at the edge of matrix 1
It is 1.2mm so that matrix 1 is shaped as gyroscope-like, the cutter head thickness that is connected with the edge of matrix 1 is also 1.2mm.
As preferred embodiment of the present utility model, radiating groove 3 is offered on matrix 1, radiating groove 3 is a circular port,
It is connected with the bottom of cutter head by a joint-cutting.The effect of radiating groove 3 is on the one hand because saw blade is through too high in working angles
Speed friction, the matrix heating of saw blade, will dilatancy, open up radiating groove and can make up the near of it and stretch rate so that maximum journey
The deformation of matrix is reduced on degree.And radiating groove can also play reduction noise, the effect of vibration-inhibition.
A coupling hole is provided with the center of circle part of saw bit matrix 1, for the connection with saw axle.And the edge of cutter head
In arc-shaped so that saw blade is more preferable to the cutting effect of material.The material of cutter head is that price is higher, the more preferable steel alloy of performance,
The material of matrix 1 is carbon tool steel, and both are welded together with the mode of soldering.
During cutting material, when cutting for the first time, with the relatively thin edge of saw bit matrix as cutter head is cut into material, incision
Then depth again improves the position of saw blade so that during thicker matrix thickness is larger up to the half of incision material thickness
Continue to cut as cutter head enters original joint-cutting in heart position so that joint-cutting is through whole material so as to material be cut off.
The utility model keeps center thickness constant by reducing the edge thickness of matrix so that ensureing saw bit matrix
Rigidity while, reduce with matrix border weld cutter head thickness so that material consume reduction.
The utility model is described in detail above in association with drawings and Examples, those skilled in the art can
Many variations example is made to the utility model according to the above description.Thus, some of embodiment details should not be constituted to this reality
With new restriction, the scope that the utility model will be defined using appended claims is used as protection domain of the present utility model.
