According to the utility model, the plurality of blades are arranged on the saw blade, and the blades are a right four-left tooth combination or a left four-right tooth combination, so that the number of contact teeth with the main section of timber is increased when the saw blade is used, the saw cutting section effect can be further improved, the saw blade is suitable for the timber with higher processing requirement on round and solid wood, and the saw blade can ensure the sharpness, the cutting section effect and the smooth arrangement and cutting.

In a preferred embodiment of the present invention, the saw blade base body has a mounting hole at the center thereof, which is adapted to the main shaft of the device, so that the saw blade is mounted on the main shaft of the device through the mounting hole in use.

As a preferable scheme of the utility model, a plurality of silencing grooves are arranged on the saw blade matrix, and the silencing grooves are communicated with the root parts of the grooves between adjacent sawteeth. Through setting up the amortization groove, can play the amortization effect when using, can also play the effect of heat extraction and prevent that the saw bit base member from warping simultaneously.

In a preferred embodiment of the present invention, the blade is a cemented carbide blade or a diamond compact. When the hard alloy sheet is adopted, the saw blade is low in cost, and when the diamond composite sheet is adopted, the saw blade is more wear-resistant and has longer service life.

As the preferable scheme of the utility model, the blade is fixed on the sawteeth through a welding process, so that the blade is stably installed and is not easy to fall off.

In a preferred embodiment of the present invention, the saw blade body is made of alloy steel.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Examples

The embodiment provides a circular saw blade capable of improving the section effect;

as shown in fig. 1 to fig. 3, the circular saw blade capable of improving a sectional effect in the present embodiment includes a circular saw blade body 1 and a plurality of blades 2, wherein a plurality of teeth are uniformly distributed on a circumferential side of the saw blade body 1, the blades 2 are fixed on sides of the teeth, and the blades 2 are a right four left teeth combination (R/LLLL teeth) or a left four right teeth combination (L/RRRR teeth). In this example, there are 120 blades on the circumference of the saw blade base, which are divided into 24 blade groups, each of which has five blades.

According to the utility model, the plurality of blades are uniformly arranged on the circumference of the saw blade, and the blades are a right four-left tooth combination or a left four-right tooth combination, namely the blades on the saw blade are divided into a plurality of blade groups, and each blade group is provided with five blades.

In this embodiment, the center of the saw blade base body 1 is provided with a mounting hole 3 adapted to the main shaft of the device, so that the saw blade can be mounted on the main shaft of the device through the mounting hole in use.

In the embodiment, a plurality of silencing grooves 4 are formed in the saw blade base body 1, and the silencing grooves 4 are communicated with the root parts of the grooves between adjacent sawteeth. Through setting up the amortization groove, can play the amortization effect when using, can also play the effect of heat extraction and prevent that the saw bit base member from warping simultaneously. Preferably, there are five sound-deadening grooves 4 uniformly arranged circumferentially at the edge of the saw blade body.

In this embodiment, the blade 2 is a cemented carbide piece or a diamond compact. When the hard alloy sheet is adopted, the saw blade is low in cost, and when the diamond composite sheet is adopted, the saw blade is more wear-resistant and has longer service life.

In this embodiment, the blade 2 is fixed on the saw teeth through a welding process, so that the blade is stably installed and is not easy to fall off.

In this embodiment, the saw blade base 1 is made of alloy steel. The high-quality alloy steel is adopted, so that the saw blade matrix has good mechanical properties.

The present embodiment solves the problem of saw blade having a good interaction force at the wood edge during trimming by changing the existing tooth shape, thereby achieving the sawing effect. The tooth-shaped saw blade is used by two or more pieces at the same time, the specific tooth shape is R/LLLL or L/RRRR, and the following details are explained by taking the sawing of two opposite sides of solid wood as an example:

1. the profile of tooth is R/LLLL tooth, divide into four left teeth of a right tooth and be a set of saw bit, uses the sawtooth clockwise installation during the installation, because of with other profile of tooth of specification compare, increased L tooth, reduced the R tooth, when using the saw bit, increased with timber main section contact tooth number, make saw cut section effect can have further promotion. The R teeth contact the wood minor profile (i.e., the scrap direction) and serve to chip and chip. Therefore, the sharpness and the cutting section effect of the saw blade can be ensured, and the saw blade can be smoothly arranged and cut. The concrete features that the L teeth are used for breaking and trimming, and the R teeth are used for breaking and trimming to prevent paste.

2. The tooth shapes are L/RRRR teeth, and the opposite is true.

3. The tooth form aims at the wood with higher processing requirement of round solid wood, can ensure that more teeth are produced on each trimming surface under the processing, the better the effect is, and the row cutting teeth are designed, so that the situation of unsmooth row cutting does not exist.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit of the present invention are intended to be included within the scope of the present invention.
