Abstract
A diamond circular saw web comprises a base body and a plurality of knife heads arranged on the edge of the base body. The knife heads are all of a ladder structure. The thicknesses of the knife heads gradually decrease in the radial extending direction from the outer edge to the inner edge. Each knife head comprises a first ladder, a second ladder and a third ladder. The inner edge of each first ladder extends toward the direction of the base body to form a protruding strip which protrudes out of the second ladder and the third ladder. According to the diamond circular saw web, cutting friction resistance and stress concentration are reduced, sharpness is improved, and the diamond circular saw web has the advantages that the service lives of the knife heads are prolonged.
Description
[technical field]
The utility model is specifically related to a kind of diamond disc.
[background technology]
Diamond saw blade be used for the cutting non-metal material particularly stone slab for known, some diamond segments compositions that it comprises a disc matrix and evenly is located at the matrix radial outside, and be provided with teeth groove between every adjacent two cutter heads, and teeth groove extends to body portion radially.Every diamond segment roughly is rectangular structure, and it is inboard affixed with matrix, and its outside is to be one section camber line at center with the matrix center of circle.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of diamond disc, has prolonged the service life of cutter head.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of diamond disc comprises a matrix and a plurality of outer peripheral cutter head of described matrix that is arranged at; Every described cutter head all is hierarchic structure, and the thickness of this cutter head increases little from the radially bearing of trend of outer edge to the inside edge gradually; Every described cutter head includes first ladder, second ladder and the 3rd ladder, and extend to described matrix direction the inside edge of described first ladder, and formation one protrudes from the raised line of described second ladder and the 3rd ladder.
The beneficial effects of the utility model are: not only reduce to cut frictional resistance and stress and concentrate, improved sharpness, and have the prolongation cutter head advantage in service life.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of a kind of diamond disc of the utility model.
[specific embodiment]
See also Fig. 1, the diamond disc 100 that a kind of sharpness is good comprises a matrix 1 and a plurality ofly is arranged at described matrix 1 outer peripheral cutter head 2; Every described cutter head 2 all is hierarchic structure, and the thickness of this cutter head 2 increases little from the radially bearing of trend of outer edge 21 to inside edge 22 gradually; Every described cutter head 2 includes first ladder 23, second ladder 24 and the 3rd ladder 25, and extend to described matrix 1 direction the inside edge of described first ladder 23, and formation one protrudes from the raised line 26 of described second ladder 24 and the 3rd ladder 25.
Please consult Fig. 1 again, the thickness of described cutter head 2 is that staged transition helps to reduce to cut frictional resistance and stress is concentrated, if the thickness of cutter head 2 is all consistent from top to bottom, then when cutting, the bottom of matrix 1 or cutter head 2 is clamped by stone easily, causes saw blade 100 to change motionless.And diamond disc 100 is when work, can produce a large amount of stone flour and water,, be mingled with the raised line 26 of the water meeting elder generation wearing and tearing cutter head 2 of stone flour owing to the setting of described raised line 26, and can not wear and tear second ladder 24 and the 3rd ladder 25, the service life of having improved cutter head 2.
Claims (1)
1. a diamond disc comprises a matrix and a plurality of outer peripheral cutter head of described matrix that is arranged at; It is characterized in that: every described cutter head all is hierarchic structure, and the thickness of this cutter head increases little from the radially bearing of trend of outer edge to the inside edge gradually; Every described cutter head includes first ladder, second ladder and the 3rd ladder, and extend to described matrix direction the inside edge of described first ladder, and formation one protrudes from the raised line of described second ladder and the 3rd ladder.
