Abstract

The utility model discloses a diamond circular saw blade fro cutting non-metal fragile materials, comprising a substrate and a diamond segmental blocks fixed along the outer ring of the substrate, wherein the blade disc of the substrate is provided with a plurality of heat outlets, the connecting line of the center points of the heat outlets is an arc line uniformly extended from the center point of the substrate, the heat outlets are uniformly provided on the arc line. The utility model adopts a plurality of holes to improve the airflow condition in a cutting process, accelerate the natural heat radiation of the heat, prolong the single working time and reduce noise.

Description

Diamond disc

Technical field

The utility model relates to a kind of instrument that is used for the cutting non-metal fragile material, particularly a kind of diamond disc.

Background technology

At present diamond disc has been widely used in the cutting processing of nonmetal fragile material, its primary structure by matrix and along the matrix outer ring fixing diamond block forms, by colding pressing and sintering processes.Its defective is: the cutterhead face of (1) matrix is a solid construction, and in cutting process, along with the quickening of cutting speed, saw blade at high temperature is affected service life; Produce air-flow when (2) rotating at a high speed owing to saw blade, the resistance of air-flow causes the saw blade rotation not smooth; (3) in when cutting because the impact of air-flow tool setting card causes bigger noise.

Summary of the invention

The utility model provides a kind of cutting efficiency high diamond disc for overcoming the deficiencies in the prior art.

The technical solution adopted in the utility model is: the diamond block that comprises matrix and fix along the matrix outer ring, several louvres of arranging on the cutterhead face of matrix.

The line of the central point of each louvre is the circular arc wire, and this circular arc line from the central point of matrix to around uniform extension, louvre is distributed on the circular arc line.

The beneficial effects of the utility model are: adopt the porous project organization of arranging, improve airflow state in the cutting process, accelerated the natural heat dissipation of blade, prolonged the single working time, reduce noise.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the front view of the utility model structure.

Fig. 2 is the left view of Fig. 1.

The specific embodiment

As shown in Figure 1, 2, the utility model is made up of matrix 1 and diamond block 2, diamond block 2 is fixed a circle along the outer ring of matrix 1, several louvres 3 of on the cutterhead face of matrix 1, arranging, the line of the central point of each louvre 3 is the circular arc wire, and the starting point of each circular arc line is the center position of matrix 1, and each circular arc line is along uniform all around, be the emitting shape extension and open, each central point of louvre 3 is distributed on the circular arc line.

When making, the utility model earlier matrix 1 blanking is processed, again at matrix 1 upper punch louvre 3, in matrix 1 outer ring chamfering, with diamond block 2 and matrix 1 cold pressing, sintering, make diamond block 2 firmly on matrix 1 outer ring, at last saw blade is adopted common method brush sheet, sprays paint, puts the first edge on a knife or a pair of scissors.

Claims

1. diamond disc, comprise matrix (1) and along matrix (1) outer ring fixing diamond block (2), it is characterized in that: several louvres (3) of on the cutterhead face of matrix (1), arranging.

2. diamond disc according to claim 1 is characterized in that: the line of the central point of each louvre (3) is the circular arc wire, and this circular arc line from the central point of matrix (1) to around uniform extension, louvre (3) is distributed on the circular arc line.
