Description

Diamond cutter, saw blade and cutter making method Technical field

The invention relates to a diamond cutter, in particular to a diamond cutter tooth and a tooth cutter manufacturing method.

technical background

Generally, diamond saw blades used for cutting stone, concrete, etc. are welded by a base and a diamond cutter. The diamond cutters currently used are usually made of metal powder for high temperature and high pressure. The cutter teeth must be cooled by liquid due to the high temperature generated during cutting, and the dust will remain in the gap during cutting. The teeth are secondarily ground to reduce the service life.

However, the conventional cutter teeth are made of metal powder, and the powder flows in a semi-molten state during the production process, and it is impossible to manufacture a hollowed-out pattern. For example, a diamond saw blade disclosed in Chinese patent CN201520014U constitutes an edge cutter. The powder is obtained by mixing diamond and some metal powders in a specific ratio, so it is necessary to provide drainage and chip flutes on the substrate, and the setting on the substrate is not as good as that provided on the teeth. However, the present invention adopts a solid carcass, and does not generate a semi-melt flow during production, thereby being capable of manufacturing a hollowed-toothed tooth, which has a good grinding effect and a long service life.

Summary of the invention

In order to overcome the deficiencies of the prior art, the present invention provides a diamond cutter having a good cutting effect and a long service life.

The diamond cutter of the present invention is made of a single or multi-layer solid carcass comprising a cutter base using a rigid material and diamond particles adhered to the rigid substrate, the number of the teeth distributed A transparent through hole. The rigid material used in the cutter base includes the belt not limited to carbon steel, or alloy steel. Or a non-ferrous metal, or a polymer material, and punching small holes or pits smaller than the diameter of the diamond particles on the substrate, laying the diamond particles on the substrate, or directly arranging the diamond particles on the rigid substrate without punching or concave The pit, pressurized heating presses the diamond particles into the solid material matrix to produce the solid carcass.

In a preferred embodiment, the tooth through holes are circular.

In a preferred embodiment, the toothed through holes are elliptical.

In a preferred embodiment, the cutting edge of the blade has an opening connected to the through hole, which is equivalent to adding a contact cutting point on the cutting surface, which increases cutting efficiency.

In a preferred embodiment, the cutting edges of the teeth are flush and have no openings.

The invention also provides a method for manufacturing diamond teeth, the following steps:

1) Determine the shape of the through hole that needs to be opened on the cutter body and select the appropriate tool;

2) punching the through hole on the solid carcass with a punching machine;

3) embedding diamond particles in the solid carcass;

4) superimposing the solid carcass of step 3) according to the required tooth thickness;

5) Welding into teeth.

In a preferred embodiment, the teeth can be welded to the base having the drain groove so that there are gaps between the teeth for better results.

The beneficial effects of the invention:

1) Using a solid carcass as a cutter, the hollow design can be performed well.

2) When the cutter teeth are cut, the contact with the cutting object instantaneously generates high temperature. Due to the hollow design, the liquid and the air can pass through the through hole opened on the cutter teeth at high speed regardless of the liquid cooling condition or the cooling condition. Achieve good cooling.

3) Improve the sharpness of the saw blade. When the general cutter is cut, only the cutter cutting surface is connected with the material. One cutting point of the touch, however, when the cutting surface of the tooth has an opening connected to the through hole, it is equivalent to increasing the cutting point and improving the sharpness.

4) When the cutter teeth are cut, the debris can be taken into the through hole of the hollow, which effectively reduces the secondary grinding and increases the service life.

Specific embodiment

In order to make the technical solutions of the present invention clearer, the present invention will be further described in detail in conjunction with the embodiments and the drawings:

Embodiment 1:

Referring to Figures 1-4, the present invention discloses a method of making a hollow diamond tooth, the cutter teeth being made without mixing metal powder, and using a solid carcass. The solid carcass is a single layer or a plurality of layers, and the material includes a belt not limited to carbon steel, or alloy steel, or a non-ferrous metal, or a polymer material.

First, it is determined that a geometric pattern of the through holes 2 that need to be opened before and after the tooth body 1 is required, and an elliptical-like through hole or a circular through hole may be provided as shown in FIG.

Secondly, through the punching machine, the through hole 2 is uniformly distributed on the cutter teeth 1. In this process, whether the cutting edge of the cutter tooth 1 is flush as shown in FIG. 3 or as shown in FIG. 2 The connected opening, that is, the punch, needs to punch out the same through hole at the cutting edge of the tooth 1. When having When opening, the cutting edge of the tooth 1 is equivalent to a few more cutting points when cutting the material, which is equivalent to increasing the sharpness. And during stamping, small holes or pits smaller than the diameter of the diamond particles are punched out, the diamond particles are laid on the carcass and diamond particles are embedded on the carcass, and finally the diamond particles are embedded in the carcass.

Finally, as shown in FIG. 3, the number of stamped teeth 1 can be selected for superposition, and finally welded to form the hollow diamond teeth of FIG.

After processing the diamond stone cutter teeth, the diamond cutter teeth can be welded according to the saw blade base body. As shown in Fig. 2, the cutter teeth of the present invention are welded on the base body 3 having the drain groove, and there is a gap between the cutter teeth, and the drainage chip is discharged. better result.

The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or within the technical scope disclosed by the present invention. Alternatives are intended to be covered by the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
