Description

Shock absorbing saw

The utility model relates to a damping saw blade, in particular to a damping saw blade which can reduce the vibration frequency of the saw blade when cutting the cutting object and reduce the noise.

Press, generally used for sawing various materials (such as: wood, acrylic sheet, etc.), the circular saw blade, the body has rigidity to cut the cutting object, and when the cutting operation is carried out, the conventional The circular saw blade rotates at a high speed, allowing the cutting edge of the peripheral edge of the circular saw blade to be quickly rotated to facilitate the cutting operation. However, when the circular saw blade is quickly rotated and the workpiece is cut and cut, the cutting edge will be The cutting object exerts great vibration and is transmitted back to the rigid saw blade body, which causes the vibration frequency to increase and generates great noise. The excessive noise value in the working environment will cause the hearing and health problems of the operator. Therefore, how to reduce the environmental noise of cutting operations, but also has a simple structure, which is the subject of the research and development of the relevant industry.

The purpose of this creation is to use a flexible adhesive to bond the saw blade, so that the single saw blade can use the adhesive to reduce the vibration frequency during cutting, thereby effectively reducing the noise of the cutting operation. .

In order to achieve the above object, the shock absorbing saw blade of the present invention comprises a plurality of sawing disks, each of which has a body, and a shaft hole is penetrated through the center of the body, and the sawing disk extends around the outer periphery of the body with a plurality of connecting portions, and the connecting portions are The plurality of saw discs are arranged in parallel, and a joint layer formed by an adhesive is disposed between the two saw discs, and the shaft holes of the saw discs are disposed opposite to the joint portion.

In the foregoing damping saw blade, each connecting portion of the sawing disc is connected with serrations.

By the above, the adhesive made by the polymer polymerization is bonded to the two saw discs, so that the saw blade can reduce the vibration frequency generated during the cutting operation, and the noise generated by the cutting operation can be effectively reduced.

The first picture is a three-dimensional appearance of the creation.

The second picture is a front view of the creation.

The third figure is an enlarged view of the portion A of the first figure.

The fourth figure is an enlarged view of the portion B of the first figure.

The fifth drawing is a cross-sectional view taken along the line A-A of the second drawing.

Referring to the first to fifth figures, it can be clearly seen from the figure that the present saw blade 10 includes a plurality of sawing disks 1 each having a body 11 through which a shaft hole 12 is inserted at the center of the body 11. And a plurality of slits 111 are formed in the outer peripheral edge of the body 11 toward the shaft hole 12, and the saw disk 1 has a plurality of connecting portions 13 extending around the outer periphery of the body 11, and the connecting portions 13 are spaced apart, and the plurality of sawing disks 1 are arranged. In the parallel combination, the bonding layer 3 formed by the adhesive is disposed between the two sawing disks 1, and the shaft holes 12 of the sawing disks 1 are disposed opposite to the connecting portion 13, and the connecting portions of the sawing plate 1 are connected. The 13-series is connected to the serrations 2, and the serrations 2 are the connecting portions 13 connecting the two adjacent saw discs 1.

By the above, when the creation is in the state of use, the saw blade 10 is assembled on the cutting machine (not shown), and the cutting machine is started to drive the saw blade 10 to rotate, so that the saw blade 10 can be cut. The operation is composed of the plurality of sawing discs 1 being bonded to each other. Therefore, there is an adhesive between the two adjacent sawing discs 1. Generally, the adhesive is made of a polymer, so the elastic adhesive is used. When the rigid sawing disc 1 is engaged in the cutting operation, the vibration excited by the impact of the cutting of the cutting object is partially offset by the adhesive, so that the cutting object and the saw blade 10 are generated during the cutting operation. The frequency of the vibration can be greatly reduced, thereby achieving the effect of reducing noise.

Therefore, the present invention is capable of solving the problems and defects of the prior art, and the key technology is that the two saw blades 1 are bonded by an adhesive, and the saw blade 10 is composed of a plurality of saw disks 1 bonded to each other, thereby utilizing polymer polymerization. The elasticity of the resulting adhesive can be used to reduce the vibration generated by the saw blade 10 during cutting, thereby reducing the noise generated by the cutting operation.
