Abstract

The utility model relates to round saw sheet used for cutting stone material, which includes a basal body and a blade-shoulder ring body which is connected with the basal body into a whole. Top surface and bottom surface of the blade-shoulder ring body are respectively provided with a saw teeth body. The two saw teeth bodies are fixedly connected with the blade-shoulder ring body. An adjusting ring mat is arranged between the two saw teeth bodies and fixed by an external rivet, in the axial direction of the blade-shoulder ring body. Each saw teeth body is fixed with a metal mesh layer at the teeth end. The metal mesh layer electroplated with a diamond grain cladding layer in the room temperature. The diamond grain on the diamond round saw sheet has great hardness, is slow in abrasion and cut with a quick speed. Knife head of the diamond round saw sheet has long service life, which produces little noise when cutting.

Description

A kind of diamond disc

The utility model relates to the saw blade of cutting stone material.

At present, employed saw blade in the processing of stone industry, comprise matrix and the sintering cutter head that is welded on the matrix outer, diamond on the sintering cutter head is to adopt HTHP sintering press forming, this saw blade through welding and the compacting of HTHP sintering, be that diamond suffers fire damage on the one hand, to adamantine intensity is reduced, quick abrasion, cutting speed is slow, and the service life of cutter head is short, has increased production cost, the carcass that is the sintering cutter head on the other hand is little to durability of diamond, and cutting noise is big.

The purpose of this utility model provides that a kind of cutting speed is fast, long service life, diamond disc that cutting noise is little.

This diamond disc, comprise circular matrix and diamond segment, its design feature is that the cylindrical side of matrix is provided with the convex shoulder ring body that is connected as a single entity with matrix, one overhanging sawtooth body respectively is housed on the end face of convex shoulder ring body and the bottom surface, two sawtooth bodies are fixedlyed connected with the convex shoulder ring body by interior rivet up and down, be provided with up and down between two sawtooth bodies at the radial outside of convex shoulder ring body, and by the fixing adjustment ring pad of outer rivet, diamond segment comprises the metal stratum reticulare that is fixed in each sawtooth body increment position, the diamond particles coating of cold galvanising on the metal level stratum reticulare.

In the above-mentioned diamond particles coating, diamond particles is the 30-70 order.

Above-mentioned metal stratum reticulare is arranged on the end face and bottom surface at each sawtooth body increment position, the metal stratum reticulare affixed with end face is outer plexiform layer, the metal stratum reticulare affixed with the bottom surface is inner plexiform layer, the diamond particles coating of cold galvanising on outer plexiform layer is sawed sword outside being, the diamond particles coating of cold galvanising on inner plexiform layer is interior saw sword, saws the thickness of the thickness of sword greater than interior saw sword outward.

As the improvement to above-mentioned diamond disc, the corresponding limbers that is provided with also is provided with the limbers in the corresponding position of adjusting the ring pad on each sawtooth body.

Diamond disc described in the utility model, because the convex shoulder ring body that is connected as a single entity with matrix, two sawtooth bodies up and down, adjust between the ring body and fix with rivet, the metal stratum reticulare at each sawtooth body increment position and diamond particles coating are to be to be lower than to electroplate under 35 ℃ the room temperature to be connected and fixed in temperature, diamond particles does not suffer fire damage on the one hand, adamantine intensity does not reduce, wearing and tearing are slow in the use, cutting speed is fast, the long service life of cutter head, reduced production cost, being carcass on the other hand greatly strengthens the hold of diamond particles, by the 45Kg/cm of former sintering cutter head ²Bring up to 1400Kg/cm ², noise is little during cutting.In addition, each sawtooth is provided with in two saw sword and two outer saw swords, during sawing sheet material, can not cut tiltedly, easily polishing in building stones processing.

Accompanying drawing shows the embodiment of this diamond saw blade, and wherein Fig. 1 is the structural representation of diamond disc, and Fig. 2 is the enlarged drawing of D part among Fig. 1, and Fig. 3 is the structural representation partial enlarged drawing of sawtooth body, and Fig. 4 is a structural representation partial enlarged drawing of adjusting the ring pad.

In the present embodiment, diamond disc comprises circular matrix 1, the cylindrical side of matrix 1 is provided with the convex shoulder ring body 2 that is connected as a single entity with matrix 1, one overhanging sawtooth body 3 respectively is housed on the end face of convex shoulder ring body 2 and the bottom surface, two sawtooth bodies 3 are fixedlyed connected with convex shoulder ring body 2 by interior rivet 4 up and down, be provided with up and down between two sawtooth bodies 3 at the radial outside of convex shoulder ring body 2, and by the fixing adjustment ring pad 6 of outer rivet 5, be fixed with diamond segment at each increment position of two sawtooth bodies 3 up and down, diamond segment comprises the metal stratum reticulare 7 affixed with the increment position, be outer plexiform layer wherein with the affixed metal stratum reticulare 7 of increment position end face, the metal stratum reticulare 7 affixed with bottom surface, increment position is inner plexiform layer, the diamond particles coating 8 of cold galvanising on outer plexiform layer is sawed sword outside being, the diamond particles coating 8 of cold galvanising on inner plexiform layer is interior saw sword, the thickness of outer saw sword is greater than the thickness of interior saw sword, the thickness of outer saw sword is according to being adjusted by the hardness of the stone material of sawing, and the diamond particles in the diamond particles coating 8 is the 30-70 order.

Be to strengthen radiating effect, in the present embodiment, also the corresponding limbers 9 that is provided with on two sawtooth bodies 3 up and down also is provided with limbers 10 in the corresponding position of adjusting ring pad 6.

In the present embodiment, label 11 and the label among Fig. 4 12 among Fig. 3 are the rivet installing hole.
