Abstract

The utility model relates to a novel diamond circular saw blade, comprising a tool bit (1) and a base body (2); the top part of the tool bit (1) is provided with U-type grooves (1a), (1b) and (1c), the U-type grooves (1a) and (1c) are in central symmetry relative to the central line of the tool bit, the depth proportion of the U-type groove (1b) and the U-type grooves (1a) and (1c) is 2.6:1, and the width proportion thereof is 1.4:1; four groups of radiating holes (2a) are arranged on the base body (2), each group of the radiating holes (2a) are arrayed in a 7 shape. The utility model solves the disadvantages of the prior art and provides the novel diamond circular saw blade which is sharp and durable, has fast heat radiation, long service life, rapid speed, stable product quality, simple processing technique and high production efficiency, thereby being widely applied to saw cutting of general materials such as concrete, sandstone and building materials.

Description

Novel diamond disc

Technical field

The utility model relates to a kind of diamond disc, and particularly a kind of novel diamond disc can be widely used in the sawing of versatile materials such as concrete, sandstone, construction material.

Background technology

At present, diamond disc is in field extensive uses such as municipal road and bridge maintenance, building, finishings.In the prior art, diamond disc needs out the top sword before sawing, is used to increase the sharpness of diamond disc, but can cause the waste of material like this, and can increase processing cost, and effect is not very desirable; In addition, under existing situation, when adopting the saw blades for dry cutting sawing, saw blade speed is fast, and the workspace belongs to semi-closed state, and heat-dissipating space is little, and the saw blade radiating rate is limited, and the accumulation of heat raises the saw blade temperature rapidly in the short time, has a strong impact on the service life of saw blade.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of sharp more durable, exempts from out that top sword, life-span are long, speed is fast, constant product quality, minimizing noise pollution, the novel diamond disc that the manufacturing cycle is short, production efficiency is high.

The technical solution of the utility model is: a kind of novel diamond disc, comprise cutter head 1, matrix 2, described cutter head 1 top is provided with

U type groove

1a, 1b, 1c, U type groove 1a and U type groove 1c are centrosymmetric with respect to cutter head 1 center line, and U type groove 1b and U type groove 1a, 1c depth scale are 2.6: 1, and width ratio is 1.4: 1; Matrix 2 is provided with 4 groups of louvre 2a, and every group of louvre 2a is 7 fonts and arranges.

The beneficial effects of the utility model are: solve existing saw blade and exempted from out the top sword, and sharp inadequately during work; The saw blades for dry cutting heat radiation is slow, the substrate temperature height, easy deformation, saw life is short, manufacturing cycle is long, and production efficiency is low, and noise pollution seriously waits not enough, a kind of sharp more durable, rapid heat dissipation is provided, the life-span is long, speed is fast, constant product quality, processing technology is simple, the manufacturing cycle is short, production efficiency is high novel diamond disc, can be widely used in the sawing of versatile materials such as concrete, sandstone, construction material.

The specific embodiment

Figure of description is an enforcement preferred version of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, 2: novel diamond disc comprises cutter head 1, matrix 2; Cutter head 1 is mixed by metal dust and diamond particles after Thermocompressed sintering and forming, and matrix 2 welds together with cutter head 1 after machining; Cutter head 1 top is provided with

U type groove

1a, 1b, 1c, and U type groove 1a and 1c are centrosymmetric with respect to cutter head 1 center line, and U type groove 1b and U type groove 1a, 1c depth scale be 2.6: 1, and width ratio is 1.4: 1; Matrix 2 is provided with 4 groups of louvre 2a, and every group of louvre 2a is 7 fonts and arranges.

Claims

1. a novel diamond disc comprises cutter head (1), matrix (2); It is characterized in that: described cutter head (1) top is provided with U type groove (1a), (1b), (1c), U type groove (1a) is centrosymmetric with respect to cutter head (1) center line with U type groove (1c), and U type groove (1b) is 2.6: 1 with U type groove (1a), U type groove (1c) depth scale, and width ratio is 1.4: 1; Matrix (2) is provided with 4 groups of louvres (2a), and every group of louvre (2a) is 7 fonts and arranges.
