Abstract

The utility model relates to hard alloy circular saw blades for cutting stones, metals and lumber, in particular to a circular saw blade for a silencing trough. The circular saw blade comprises a big and thin metal plate-like saw blade body, teeth distributed around the outer circumference of the saw blade body, diamond tips or hard alloy tips welded on the teeth according to different materials to be cut, a central hole in the centre of the saw blade body, rotating hole outside the central hole, fabrication holes in the middle of the radius, and a plurality of bent noise reduction cutting slits uniformly cut on the saw blade body. The utility model has the advantages of obviously reducing the noise generation in the use of diamond circular saw blades, metal cutting hard alloy circular saw blades, and lumber cutting hard alloy circular saw blades, greatly reducing the pollution of the noise to the surroundings, prolonging the service life of the circular saw blade to a great extent, and improving the cutting quality.

Description

Noise reduction groove saw blade

Technical field

The utility model relates to cutting stone material, metal, timber sintered carbide circular saw, especially a kind of noise reduction groove saw blade.

Background technology

Conventional diamond disc and sintered carbide circular saw can send very big noise in cutting stone material, steel and timber process, surrounding environment has been produced huge noise pollution.Because saw blade noise in use is to be produced by saw blade vibration in use, noise is big more, illustrate that saw blade is big more in the saw blade vibration of use, especially when saw blade intrinsic frequency and saw blade vibration frequency generation resonance, the noise that produces can be bigger, and this has reduced the service life of saw blade to a great extent.

Summary of the invention

The purpose of this utility model is in order to solve diamond disc and the sintered carbide circular saw excessive problem of noise in use, and provide a kind of by changing saw blade sheet body structure, thereby change Natural Frequency of Circular Saw, reach and reduce the noise of saw blade in cutting process, and further improve the saw blade noise reduction groove saw blade in service life.

The technical scheme that the utility model solves this technical problem employing is: a kind of noise reduction groove saw blade, comprise a big and thin round metal plate-like blade bodies, be distributed with sawtooth on the described blade bodies excircle, by being welded with diamond segment or carbide bit on the different described sawtooth of sawing material, there is centre bore at the blade bodies center, centre bore has driving hole outward, in the radius middle part fabrication hole is arranged, and evenly is cut with several crooked noise reduction joint-cuttings on blade bodies.

Compared with prior art, the beneficial effects of the utility model are: can significantly reduce diamond disc, cutting metal sintered carbide circular saw and cutting timber sintered carbide circular saw generating noise in use, reduce the pollution of noise greatly to surrounding environment, and the service life of improving saw blade to a great extent, improve sawing quality.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment 1 as shown in Figure 1, this noise reduction groove saw blade is a kind of diamond disc, its blade bodies 1 is a big and thin rosette, diameter is generally Φ 200mm-Φ 3500mm.Be distributed with sawtooth 2 on this blade bodies 1 excircle, be welded with diamond segment 3 on the excircle of this sawtooth 2, the shape and the quantity of this sawtooth 2 and cutter head 3 are decided according to cutting material and purposes, between each cutter head 3 tank 4 are arranged; The center of this blade bodies 1 is provided with a centre bore 6, and the aperture is generally Φ 15mm-Φ 200mm, and centre bore 6 peripheries have four driving holes 7, and the aperture is generally Φ 7mm-Φ 30mm; In blade bodies 1 radius middle part two fabrication holes 8 are arranged, the aperture is generally Φ 13mm-Φ 40mm, evenly is cut with several crooked noise reduction joint-cuttings 5 on blade bodies 1.

Embodiment 2 as shown in Figure 2, this noise reduction groove saw blade also is a kind of diamond disc, compares with embodiment 1 described diamond disc, only the shape difference of noise reduction joint-cutting 5.

Embodiment 3 as shown in Figure 3, this noise reduction groove saw blade is a kind of sintered carbide circular saw, its blade bodies 1 is a big and thin rosette, diameter is generally Φ 200mm-Φ 2200mm, be distributed with sawtooth 2 on this blade bodies 1 excircle, be welded with carbide bit 3 on the excircle of sawtooth 2, the shape and the quantity of sawtooth 2 and cutter head 3 are decided according to cutting material and purposes; Between each cutter head 3 chip pocket 10 is arranged, the following location interval in chip pocket 10 bottoms is provided with six heat groove 9 that rises; The center of blade bodies 1 is provided with a centre bore 6, and the aperture is generally Φ 15mm-Φ 200mm; Centre bore 6 peripheries have four driving holes, and the aperture is generally Φ 7mm-Φ 30mm; In blade bodies 1 radius middle part two fabrication holes 8 are arranged, the aperture is generally Φ 13mm-Φ 40mm; According to cutting material and saw situation, on blade bodies 1, evenly be cut with several crooked noise reduction joint-cuttings 5.

Embodiment 4 as shown in Figure 4, this noise reduction groove saw blade also is a kind of sintered carbide circular saw, compares with embodiment 3 described sintered carbide circular saws, only the shape difference of noise reduction joint-cutting 5.

Claims

1. noise reduction groove saw blade, comprise a big and thin round metal plate-like blade bodies, be distributed with sawtooth on the described blade bodies excircle, by being welded with diamond segment or carbide bit on the different described sawtooth of sawing material, there is centre bore at the blade bodies center, and centre bore has driving hole outward, in the radius middle part fabrication hole is arranged, it is characterized in that, on blade bodies, evenly be cut with several crooked noise reduction joint-cuttings.
