Abstract
An alloy steel saw blade comprises a knife head body (1), a knife head accessory body(2)and a base (3) provided with a flume (7) and communicated with the knife head body (1) and the flume (7) of the knife head accessory body (2). The utility model is characterized in that a plurality of adhesive layers (5) is arranged in the two sides of the flume (7) in the joint of the knife head body (1), the knife head accessory body(2)and the base (3). The utility model adds the triangular adhesive layers in the two sides of the flume which have the function of sides grinding, thus reducing the knife head extrusion in the side direction, reducing the right and left vibration when the saw blade cuts, reducing the resistance in the process of cutting, improving the cutting efficiency of the saw blade, increasing the interface between the knife head and the base, increasing the occlusion force and the impact force, and avoiding the falling off of the knife head when the saw blade cuts.
Description
Technical field
The utility model relates to a kind of cutting tool, especially a kind of steel alloy saw blade.
Background technology
At present, the saw blade that is used for uses such as cutting marble, granite, refractory material be mostly by saw bit matrix and after being fixed in diamond composite material high temperature sintering on the saw blade hot pressing form, the structure of its saw blade generally includes cutter head matrix, cutter head accessory body and cutter head main body, matrix and this saw blade exist in its manufacture process and in produce using: when 1, one or several diamond cutting edges damage, need keep in repair and change cutting edge timely; 2, leave tank on the saw blade mostly, in use owing to the existence of cooling nozzle, the adamantine cutting output of envoy's piece each several part is inhomogeneous, as the groove tooth damage of a tank takes place, and then this tooth promptly can not be used again, and waste is very big, and cost is very high; 3, the diamond cutting output of saw blade front end strengthens the saw blade power that is hit greater than the rear portion, and the unstable cutter head of saw blade comes off from body portion easily.
Summary of the invention
The purpose of this utility model is to overcome above deficiency; a kind of steel alloy saw blade is provided, and is the height that increases jagged edges, has played and has protected steel matrix not to be subjected to the effect of damage of rock; improve the snap-in force of sawtooth and steel matrix simultaneously, prevent that saw blade from coming off because of impact when high speed rotating.
The technical solution of the utility model realizes in the following manner: a kind of steel alloy saw blade, comprise cutter head and matrix, cutter head is made up of cutter head main body and cutter head accessory body, have tank on the described matrix, respectively with the cutter head main body, the tank of cutter head accessory body communicates, and it is characterized in that: the tank both sides of main body cutter head, accessory body cutter head below and matrix junction increase the even number adhesion layer.
Above-mentioned adhesion layer is an isosceles triangle.
The thickness of above-mentioned adhesion layer is greater than the height of matrix.
The quantity of above-mentioned adhesion layer is less than the quantity of tank.
The utility model plays the side ablation owing to increased the triangle adhesion layer in the tank both sides, thereby the lateral compression of cutter head is reduced, make vibrations minimizing about the saw blade cutting, and then the resistance in the minimizing cutting process, improve the saw blade cutting efficiency, increased cutter head and matrix contact-making surface, improved snap-in force and impulsive force, prevent that saw blade when cutting cutter head from coming off.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a cutaway view of the present utility model.
Fig. 3 is an adhesion layer schematic diagram of the present utility model.
In the drawings, the 1st, cutter head main body, the 2nd, cutter head accessory body, the 3rd, matrix, the 4th, cutter head front end, the 5th, adhesion layer, the 6th, cutter head rear end, the 7th, tank.
The specific embodiment
In Fig. 1 Fig. 2, the utility model comprises cutter head and matrix 3, cutter head is made up of cutter head main body 1 and cutter head accessory body 2, below main body cutter head 1 and accessory body cutter head 2, have the tank 7 that is evenly distributed with matrix 3 junctions, described tank 7 is eight, tank 7 both sides are provided with the adhesion layer 5 of four isosceles triangles equably, and the thickness of main body cutter head 1 and accessory body cutter head 2 is greater than the thickness of matrix 3 in the present embodiment.
In Fig. 3, adhesion layer 5 is isosceles triangular structures, and its thickness is also greater than the thickness of matrix 3, and is identical with the thickness of main body cutter head 1 and accessory body cutter head 2.
The height of the jagged edges that the utility model increases has played the effect of protecting matrix 3 not to be subjected to damage of rock, improves the snap-in force of sawtooth and steel matrix simultaneously, prevents that saw blade from coming off because of impact when high speed rotating.
Cutter head main body 1 and accessory body 2 are to adopt diamond abrasive and metal dust to mix among the embodiment of the present utility model, and are pressed into semi-finished product with matrix 3 in mould, and sintering forms then.Wherein adhesion layer 5 also is the diamond abrasive working lining, and is identical with the accessory body tool tip material with the main body cutter head.
The utility model is in use because the existence of tank 7, make the adamantine cutting output of saw blade each several part inhomogeneous, the diamond cutting output of cutter head front end 4 is greater than cutter head rear portion 6, stressed size is inhomogeneous when being hit power in order to change saw blade, the unsettled situation of saw blade, increase triangle adhesion layer 5 and can play the side ablation in tank 7 both sides, thereby the lateral compression of cutter head is reduced, make vibrations minimizing about the saw blade cutting, and then the resistance in the minimizing cutting process, improve the saw blade cutting efficiency.Owing to the existence of adhesion layer, increased the contact-making surface of cutter head and matrix, increased snap-in force, the impulsive force that cutter head can be born strengthens, and cutter head comes off when preventing the saw blade cutting.
Because in use the saw blade great majority of ∮ 105-∮ 125 small dimensions all are portable cuttings, saw bit matrix and talus glacier produce fretting wear.Because the gauge wear and the side wear of cutter head are inconsistent, gauge wear is bigger than the side.In portable cutting, when the cutter head working lining consumed, the friction of saw bit matrix and talus glacier strengthened, and causes binding, and this will cause the wearing and tearing and the distortion of saw bit matrix.The triangle adhesion layer also has diamond abrasive, also plays ablation, and the protection matrix is not subjected to the damage of landwaste, makes the rigidity of saw bit matrix unaffected, guarantees that joint-cutting is straight, reduces saw blade suffered resistance in cutting process, increases work efficiency.
