Noise-reducing saw blade for timber cutting

Abstract

The invention discloses a noise-reducing saw blade for timber cutting. The noise-reducing saw blade comprises a copper core plate, a plurality of air holes are formed in the outer circumference of thecopper core plate, cutting disks are arranged on two sides of the copper core plate and provided with fixing holes penetrating the copper core plate, the outer edges of the cutting disks extend outwards to go beyond the outer edge of the copper core plate, a plurality of rubber posts surrounding the copper core plate are arranged between the two cutting disks, flared elastic bodies are arranged at two ends of the rubber posts, threaded rods are arranged in the rubber posts, the two cutting disks are fixed to two ends of the threaded rods and are connected with the copper core plate through pins penetrating a plurality of surrounding fixing holes, a plurality of saw teeth are arranged on the outer circumferential faces of the cutting disks, 10-15 saw teeth are designed in a group, an inwardly extending noise-reducing seam is formed in the root of one of each saw tooth group, and noise-reducing pillars are inlaid into the ends of the noise-reducing seams. The noise-reducing saw blade for timber cutting is not prone to being overheated and causing fire and long in service life without sharp noise.

Description

technical field [0001] The invention belongs to the field of saw blades for wood cutting, in particular to a sound-absorbing saw blade for wood cutting. Background technique [0002] Saw blades tend to heat up when cutting wood, especially when cutting thicker and harder wood. In the context of mass production in modern industry, saw blades in factories are often overloaded for a long time. In the working state, the heat is particularly serious, causing the saw blade to overheat. The overheating of the saw blade will not only shorten the life of the saw blade, but also easily ignite the sawdust, which will cause a fire. In addition, the thickness of the existing saw blade is relatively thin, and the saw blade is easy to resonate when cutting wood, so that a sharp whistling sound is emitted. Therefore, the existing saw blades have the disadvantages of being prone to overheating, shortening the service life of the saw blade, causing a fire easily, and also having the disadvan...

Problems solved by technology

[0002] Saw blades tend to heat up when cutting wood, especially when cutting thicker and harder wood. In the context of modern industrial mass production, saw blades in factories are often overloaded for a long time. In the working state, the heat is particularly serious, causing the saw blade to overheat. The overheating of the saw blade will not only shorten the life of the saw blade, but also easily ignite the sawdust, which will cause a fire

In addition, the existing saw blades are relatively thin, and when cutting wood, the saw blades tend to resonate, resulting in a sharp whistling sound

Therefore, the existing saw blades have the disadvantages of being prone to overheating, shortening the service life of the saw blade, causing a fire easily, and having the disadvantage of making a sharp whistling sound.
