Anti-edge-breakage low-noise saw blade base body

Abstract

The invention provides an anti-edge-breakage low-noise saw blade base body. An anti-edge-breakage low-noise saw blade base body comprises a first saw blade body and a second saw blade body, the first saw blade body and the second saw blade body are oppositely arranged and connected with each other, a plurality of first vibration absorption grooves are formed in the surface, connected with the second saw blade body, of the first saw blade body, and a plurality of second vibration absorption grooves are formed in the surface, connected with the second saw blade body, of the second saw blade body. A plurality of second vibration absorption grooves are formed in the surface, connected with the first saw blade body, of the second saw blade body, each first vibration absorption groove corresponds to one second vibration absorption groove to form a vibration absorption cavity, and the section of each first vibration absorption groove and the section of each second vibration absorption groove are both in an arc shape. By means of the vibration absorption cavity, most of vibration energy waves of the saw blade base body are focused, vibration energy is effectively dissipated, vibration and noise of the saw blade base body are effectively restrained, the vibration and noise absorption capacity of the saw blade base body is improved, and the weight of the saw blade base body is reduced.

Description

technical field [0001] The invention relates to a saw blade base, in particular to an anti-chipping and low-noise saw blade base, which belongs to the technical field of saw blade processing. Background technique [0002] The saw blade is an important cutting tool in the industry. The saw blade is generally made of high-speed steel plate, and the saw blade base is the primary product in the processing of the saw blade. The saw blade is obtained by subsequent processing of the saw blade base. The production of the saw blade base is generally as follows: first, the steel plate is laser cut, then the teeth are ground, and then the saw blade base is obtained by heat treatment, leveling, flat grinding and other processes. [0003] Existing saw blade substrates usually have a single-layer structure or a double-layer structure. Among them, the saw blade substrate with single-layer structure, in order to reduce the weight of the saw blade substrate and reduce energy consumption, th...

Problems solved by technology

[0005] Although the viscose composite sound-absorbing saw blade matrix reduces the vibration frequency and noise transmission of the saw blade, the reduction mainly depends on the viscose layer. In order to obtain a better vibration and noise reduction effect, a thicker viscose layer and a larger viscose are required. The contact area between the adhesive layer and each layer of metal plates requires at least three layers of metal plates to be processed, which increases the processing cost and increases the weight of the saw blade base, which is not conducive to reducing energy consumption
