Abstract

The utility model relates to a sandstone diamond stone blade comprising a basal body and a diamond tool bit. Through holes are arranged in the middle of the basal body; the basal body is evenly provided with a plurality of air holes which evenly divide the outer edge of the basal body into a plurality of basal body margins; two rows of small holes in alternate arrangement are evenly distributed on the outer side edges of the basal body margins; and diamond tool bits are fixed on the basal body margins. The utility model has the advantages that the tartness is improved, stone chips can be discharged from a groove in the cutting process, the resistance is reduced, the working efficiency is improved, the materials are saved and the cost is reduced.

Description

A kind of sandstone diamond saw blade

Technical field

The utility model relates to a kind of sandstone diamond saw blade.

Background technology

The sandstone diamond saw blade is a kind of cutting tool, is widely used in stone material, the processing of hard brittle materials such as pottery.The sandstone diamond saw blade mainly is made up of two parts, matrix and cutter head.Matrix is the main support part of bonding cutter head, cutter head then is the part that in use plays cutting, cutter head can in use and constantly consume, matrix then can not, why cutter head can play cutting is because wherein contain diamond, diamond is as the hardest present material, the processed object of its friction cuttings in cutter head.Diamond particles then is wrapped in cutter head inside by metal.At present, the sandstone diamond saw blade of prior art comprises matrix and cutter tooth, it is by diamond metal powder and matrix are put into punching block compression moulding, put into liquid-phase sintering in the sintering furnace then, the matrix of this kind saw blade combines the strength of just leaning on cutter tooth and matrix to inlay with cutter tooth portion, adhesion is little.In use normal coping saw blade rotating speed is too high or to be cut the resistance or the user of material firmly excessive, usually cause cutter tooth to break away from from matrix, cutter tooth flies out at a high speed, be easy to cause industrial accident, and the diamond in the saw blade is in long-term wearing and tearing, under the situation of bump fragmentation, descend significantly at 1/3 o'clock sharpness of residue, make the workload of sandstone diamond saw blade cutting stone material big, operating rate is slow, the energy consumption height.

The utility model content

The purpose of this utility model provides a kind of sandstone diamond saw blade, under the prerequisite that guarantees cutting quality, increases the adhesion of cutter tooth and matrix, increases work efficiency, and reduces cost.

The purpose of this utility model is to be achieved through the following technical solutions: a kind of sandstone diamond saw blade, comprise matrix and diamond segment, the middle part of described matrix is provided with through hole, some wind hole evenly distributes on the matrix, some wind hole is divided into some matrixes limit page or leaf with the outer rim of matrix, the outer ledge place of matrix limit page or leaf is evenly distributed with staggered two row's apertures, fixed diamond cutter head on the page or leaf of matrix limit.

The beneficial effects of the utility model are: improved sharpness, aggregate chips can be discharged in aperture in the process of cutting, reduces resistance, has improved operating efficiency; And saved raw material, reduced cost.

Description of drawings

With reference to the accompanying drawings the utility model is described in further detail below.

Fig. 1 is the structural representation of the described sandstone diamond saw blade of the utility model embodiment; Fig. 2 is the cutaway view of the described sandstone diamond saw blade of the utility model embodiment; Fig. 3 is the structural representation after the described sandstone diamond saw blade of the utility model embodiment is removed diamond segment.

Among the figure: 1, matrix; 2, diamond segment; 3, through hole; 4, wind hole; 5, matrix limit page or leaf; 6, aperture.

The specific embodiment

As Figure 1-3, the described a kind of sandstone diamond saw blade of the utility model embodiment, comprise matrix 1 and diamond segment 2, the middle part of described matrix 1 is provided with through hole 3, some wind hole 4 evenly distributes on the matrix 1, some wind hole 4 is divided into some matrixes limit page or leaf 5 with the outer rim of matrix, and the outer ledge place of matrix limit page or leaf 5 is evenly distributed with staggered two row's apertures 6, fixed diamond cutter head 2 on the matrix limit page or leaf 5.

During concrete the use, by the aperture 6 on matrix limit page or leaf 5, make metal dust pass matrix limit page or leaf 5, compacting sintering makes metal dust be post shapes and penetrates in the middle of matrix limit page or leaf 5 again, thereby has increased the bond strength of matrix 1 with diamond segment 2.

Claims

1. sandstone diamond saw blade, comprise matrix (1) and diamond segment (2), the middle part of described matrix (1) is provided with through hole (3), matrix (1) is gone up the some wind holes (4) that evenly distribute, some wind hole (4) is divided into some matrixes limit page or leaf (5) with the outer rim of matrix, it is characterized in that: the outer ledge place of matrix limit page or leaf (5) is evenly distributed with staggered two row's apertures (6), and matrix limit page or leaf (5) is gone up fixed diamond cutter head (2).
