Abstract
The invention discloses a multi-layer diamond saw blade bit and belongs to diamond saw blade tools. The multi-layer diamond saw blade bit consists of cutting layers and auxiliary cutting layers, wherein the sum of the number of the cutting layers and the number of the auxiliary cutting layers is odd, the auxiliary cutting layers are made of graphite materials and have a wedge-shaped structure with the wide top and narrow bottom; the bottom edge of the planar shape is in a V shape; and the other edge of the planar shape are flush with the tool bit. The multi-layer diamond saw blade bit is simple in structure and convenient to operate, and the cutting sharpness of the saw blade can be gratly improved and the service life of the saw blade can be greatly prolonged; and moreover, the multi-layer diamond saw blade bit is widely applied to road construction, constructional engineering and stone machining.
Description
Technical field
The present invention relates to the diamond saw blade field of tool, is a kind of multi-layer diamond saw blade tip specifically.
Background technology
Diamond saw blade is widely used in road construction, architectural engineering and processing of stone as a kind of cutting tool.Diamond saw blade mainly is welded to form by saw bit matrix and diamond segment.Diamond segment also claims diamond segment, is formed by diamond and metal dust mixing, compacting, dress mould and sintering, and cutter head divides individual layer and sandwich construction.The sandwich construction diamond segment has better sharpness, but traditional sandwich construction cutter head has the following disadvantages: the one, and the assisted machining layer is the mixture of iron plate, copper sheet or other metal dusts, cost is higher, complex manufacturing technology; The 2nd, have the interface between assisted machining layer and the cutting lay, and because of its powder composition differ cause more easily the layer with layer between alloying level different; The 3rd, the assisted machining layer can not in time form chip area owing to have stronger nonferromagnetic substance at the cutting initial stage, influences the cutting sharpness of saw blade; The 4th, saw blade cutting later stage assisted machining layer approach exhaustion, and cutting lay does not consume fully yet, can damage saw bit matrix but continue to use, and therefore causes the waste of cutting lay.
Summary of the invention
The objective of the invention is at existing in prior technology the problems referred to above, a kind of simple in structure, easy to operate diamond saw blade is provided, to increase substantially cutting sharpness and the service life of saw blade.
Technical scheme of the present invention is: a kind of multi-layer diamond saw blade tip, become the cutting lay of odd number and assisted machining layer to constitute by sum, described assisted machining layer is made by graphite material, and thickness is wedge structure wide at the top and narrow at the bottom, the flat shape base is V-shaped, and other limits are concordant with cutter head integral body.
The angle on described assisted machining layer V-type base is to be 170 in the saw blade tip of 350mm-800mm at diameter
0-175
0Be to be 165 in the saw blade tip of 1000mm-3000mm at diameter
0-170
0
Described graphite material can be formed by graphite flake, also can be formed by graphite paper or graphite powder.
Technical advantage of the present invention exists:
1, graphite material can form chip area fast as the assisted machining layer, makes diamond saw blade can have good sharpness at the use initial stage;
2, the darker chip area that forms owing to graphite linings wearing and tearing in the working angles can be stored more smear metal and avoids cutter head to the regrind of chip removal, sharpness and the service life of raising saw blade;
3, the self-heating of graphite material in sintering process can be strengthened the alloying level between the diamond segment interior metal material;
4, the specific geometry of graphite linings can be guaranteed alloying intensity and diamond segment uniform sharpness and wearability in working angles of diamond segment;
5, reduce the use amount of diamond segment to metal material, saved metals resources.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
A kind of multi-layer diamond saw blade tip of the present invention becomes the cutting lay of odd number and assisted machining layer to constitute by sum, and cutting lay is the mixture of diamond and metal dust; The assisted machining layer is made by graphite flake, and thickness is wedge structure wide at the top and narrow at the bottom, and the flat shape base is V-shaped, and other limits are concordant with cutter head integral body.
Embodiment 1
Be in the saw blade tip of 800mm at diameter, the angle on assisted machining layer (being graphite flake layer) V-type base is 175
0
Embodiment 2
Be in the saw blade tip of 1600mm at diameter, the angle on assisted machining layer (being graphite flake layer) V-type base is 170
0
Claims (3)
1. multi-layer diamond saw blade tip, become the cutting lay of odd number and assisted machining layer to constitute by sum, it is characterized in that the assisted machining layer made by graphite material, thickness is wedge structure wide at the top and narrow at the bottom, the flat shape base is V-shaped, and other limits are concordant with cutter head integral body.
2. a kind of multi-layer diamond saw blade tip according to claim 1 is characterized in that the angle on described assisted machining layer V-type base, is to be 170 in the saw blade tip of 350mm-800mm at diameter
