Embodiment 1

[0024] Such as figure 1 Among them, a viscose composite sound-absorbing saw blade base includes a saw blade base, a central hole 1 is provided in the center of the saw blade base, and the saw blade base is formed by bonding three layers of metal plates through an adhesive layer 2 . On the one hand, the provided adhesive layer 2 can ensure the overall connection strength of the three-layer metal plates and the rigidity of the saw blade substrate, and on the other hand, as a damping medium, the vibration and noise generated during sawing can be effectively reduced.

Embodiment 2

[0026] In a preferred solution, the three layers of metal plates have the same thickness, which is not shown in the figure. This structure is convenient for processing, and as a mass production on the production line, the processing cost of this structure is the lowest.

Embodiment 3

[0028] The preferred solution is as figure 1 Among them, the metal plate has three layers, and the thickness of the middle metal plate 5 is greater than the thickness of the outer matrix 3 . After testing, the noise reduction effect of this structure is better than that of Example 2. The specific reason is unknown, but it is speculated that the vibration frequencies generated will cancel each other out due to the different thicknesses of the metal plates.

Abstract

A viscose composite sound-absorbing saw blade base body comprises a saw blade base body, a central hole is arranged in the center of the saw blade base body, and the saw blade base body is formed by bonding multiple layers of metal plates through adhesive layers. The metal plate has three layers, and the thickness of the middle metal plate is greater than the thickness of the outer matrix. The adhesive layer is also provided with a welding layer. The invention provides a viscose compound sound-absorbing saw blade matrix. By adopting multi-layer metal plates to glue the composite structure, the saw blade matrix itself has good strength, rigidity and plasticity, so that on the one hand, it can effectively reduce the cutting deflection, and on the other hand On the one hand, it can improve the self-absorption and cushioning performance of cutting vibration. The set viscose layer acts as a damping medium to effectively reduce the vibration and noise generated during sawing.

Description

technical field [0001] The invention relates to a saw blade base body, in particular to a viscose composite sound-absorbing saw blade base body. Background technique [0002] Composite sound-absorbing diamond saw blade matrix is ​​currently widely used in the form of two-layer metal plates sandwiching copper skin and other types of media, and the three are fixed together by spot welding. This composite sound-absorbing saw blade matrix has a certain sound-absorbing effect. However, due to the current environmental protection requirements are getting higher and higher, the sawing noise needs to be further reduced, thus putting forward higher requirements for the noise reduction and noise reduction performance of the sound-absorbing saw blade base. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a viscose composite sound-absorbing saw blade matrix, which can further reduce the noise generated during sawing on the pr...
