Abstract

The utility model relates to a silence circular saw blade. The saw blade of the utility model or a basal body of the saw blade is a laminated structure formed in a mode that two layers or more than two layers of working basal blades (6) and silencing blades (7) which are arranged among the working basal blades (6) are integrally connected through a plurality of weld spots (3). As the working basal blades and the silencing blades are made different materials, the inherent vibration frequency of the working basal blades and the inherent vibration frequency of the silencing blades are different; accordingly, the resonance is avoided, and the noise is reduced. In addition, as the utility model adopts a layered structure, the internal stress can be effectively reduced or eliminated; the strength can be improved under the condition of equal weight, or the raw material use level can be saved under the precondition that the intensity is guaranteed.

Description

Silent circular saw blade

The utility model belongs to annular saw, particularly relates to a kind of silent circular saw blade.

At building, woodenware production and mechanical processing industry, in the processing to stone material, timber, steel etc., annular saw is one of instrument the most commonly used, has advantages such as cheap, easy to use, applied range, but also has the defective that noise is big, intensity is low.Existing patented technology has been done some improvement at its defective, as: No. 93200467 patents " combined type saw bit matrix ", a kind of saw bit matrix that is formed by stacking by multi layer substrate is disclosed, can reduce or eliminate the matrix internal stress effectively, can the intensity of saw blade be increased.No. 96236950 patents " superhard material silent circular saw blade " provide a kind of noise elimination saw blade for another example, and its noise reduction realizes by processing some noise eliminations crack or sound attenuation hole on saw bit matrix.Above-mentioned two patents have certain positive effect to intensity and the reduction noise that improves saw blade respectively, but its weak point is, the former does not solve the problem of noise when improving saw blade intensity, and the latter has then sacrificed the intensity of saw blade when solving noise problem.

The purpose of this utility model promptly is to provide a kind of novel saw blade that can reduce noise and its intensity not had negative effect.

Silent circular saw blade comprises matrix (2) and cutting portion (1), installing hole (5) is arranged on the matrix, it is characterized in that saw blade or saw bit matrix are two-layer or two-layer above work substrates (6) and place the bloop (7) between the work substrate to be whole laminated construction by solder joint (3) connection.

Because saw blade of the present invention or saw bit matrix are to be formed by stacking by the bloop between work substrate and the work substrate, and both adopt different materials to make, therefore its intrinsic vibration frequency difference when vibration takes place has been avoided generation resonance, thereby has been greatly reduced noise.In addition,, can effectively reduce or eliminate the saw blade internal stress, can under the situation of equivalent weight, improve its intensity because saw blade or saw bit matrix adopt hierarchy, or under the prerequisite that guarantees its intensity, the consumption that saves material.

The accompanying drawing part further discloses embodiments of the invention:

Fig. 1 installs the saw blade partial schematic diagram of cutting portion additional;

Fig. 2, the whole saw blade partial schematic diagram of big direct tooth type;

Fig. 3, the whole saw blade partial schematic diagram of pointed tooth type;

Fig. 4, the saw bit matrix schematic partial sectional view.

The saw blade that installs cutting portion additional as shown in Figure 1 should be used for the particularly processing of stone material of building materials, and its cutting portion (1) is welded on the saw bit matrix on (2), and saw bit matrix has installing hole (5) and tank (4); Fig. 3 and big direct tooth type and the whole saw blade of pointed tooth type shown in Figure 4 are suitable for the fervent and timber processing of steel respectively, and its cutting portion (1) is an overall structure with saw bit matrix (2).Fig. 3 and saw blade shown in Figure 4 and saw bit matrix shown in Figure 1, its section structure are to connect the laminated construction that forms by some solder joints (3) by two-layer work substrate (6) and one deck bloop (7) therebetween as shown in Figure 5.

In the above-described embodiments, make the work substrate material selection be the carbon element steel alloy, bloop then adopts Copper Foil.Certainly select for use other material also to be fine, as, the work substrate is made with carbon steel, and bloop is selected aluminium foil for use, and effect is the same.

Claims

1, a kind of silent circular saw blade, comprise matrix (2) and cutting portion (1), installing hole (5) is arranged on the matrix, it is characterized in that, saw blade or saw bit matrix are two-layer or two-layer above work substrates (6) and place the bloop (7) between the work substrate to be whole laminated construction by solder joint (3) connection.

2, silent circular saw blade according to claim 1, its feature are that also tank (4) is arranged on the said saw bit matrix.
