For a better understanding of the objects, structure and function of the present utility model, a diamond circular saw blade with a shaped cutting head according to the present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-3, the diamond circular saw blade with the special-shaped tool bit comprises a saw blade substrate 1, wherein a central mounting hole 2 is formed in the central part of the surface of the saw blade substrate 1, a plurality of noise reduction holes 3 are formed in the surface of the saw blade substrate 1, four noise reduction holes 3 are formed in the surface of the saw blade substrate 1 in a circumferential array, and through the arrangement of the four noise reduction holes 3, the acoustic radiation area is reduced, so that the sound field distribution tends to be more uniform, and noise generated during the operation of the saw blade is greatly reduced. The edge of saw bit base member 1 is provided with a plurality of basin 7 that are circumference array distribution, and the edge of saw bit base member 1 is located the department between two basin 7 and all is provided with tool bit 4, and the thickness of tool bit 4 is greater than the thickness of saw bit base member 1, and the both sides wall of tool bit 4 all protrusion saw bit base member 1, and the thickness of tool bit 4 is greater than saw bit base member 1 thickness, plays the guard action to saw bit base member 1, can effectively reduce the fish tail and the wearing and tearing that cause saw bit base member 1 when cutting, avoids saw bit base member 1 to split, has improved the security performance of product greatly. The middle part of the edge of the cutter head 4 is provided with the notch 5, and the notch 5 is of a hook-shaped structure, so that the top area of the whole cutter head 4 is relatively small, the contact area between the top of the cutter head 4 and an object during cutting is reduced, the cutting resistance is reduced, and the cutting speed is improved. The V-shaped grooves 6 are formed in the two side walls of the cutter head 4, the included angle of each V-shaped groove 6 is an obtuse angle, fine powder and fragments can be prevented from accumulating in the cutting joint through the arrangement of the V-shaped grooves 6, heat dissipation is fast during cutting, chip removal is fast, and cutting efficiency is improved. The both ends lateral wall of tool bit 4 all is provided with inclined plane 9, and the inclined plane of every adjacent two tool bit 4 all forms a trapezoidal mouth 8, and the size in trapezoidal mouth 8 outside is greater than the size of inboard, and the size of inboard equals with the opening size of basin 7, has certain forced air cooling effect in the cutting process through the setting of trapezoidal mouth 8, reduces tool bit 4 temperature to the size in trapezoidal mouth 8 outside is greater than the size of inboard, has further improved chip removal efficiency. The tool bit 4 comprises a welding layer 10 contacted with the saw blade matrix 1 and a matrix 11 contacted with the welding layer 10, wherein a plurality of irregularly distributed weak embedding layers 12 are filled in the matrix 11, and diamond particles 13 are wrapped in each weak embedding layer 12.

The design method of the cutter head 4 is as follows: firstly, mechanically wrapping a layer of tungsten carbide powder on the surface of diamond, then uniformly mixing the treated diamond with matrix powder, and then carrying out die filling sintering. The treated tool bit interlayer has a layer of tungsten carbide powder without bonding property between the matrix and the diamond, so that the embedding capability of the matrix to the diamond is weakened, and the diamond can be automatically separated from the matrix under the condition that the matrix is not abraded greatly, thereby realizing the layer replacement of the diamond. In designing and manufacturing the tool bit 4, the concentration of diamond is smaller than that of the weak embedding layer 12, and the concentration depends on the stone material. The diamond falling speed of the tool bit 4 is controlled by the thickness of the tungsten carbide weak embedding powder layer wrapped on the surface of the diamond, and the thicker the tungsten carbide weak embedding powder layer is, the faster the diamond falling speed is; conversely, the slower the diamond fall-off speed.

The object is cut by the saw blade, and the object is scored by shearing and impacting the diamond particles which are more and smaller on the edge surface of each tool bit, so that the object is cut. When the saw blade tool bit works, after the cutting face of the tool bit 4 is contacted with an object, under the action of radial pressure and rotation force, the lip face of the tool bit weak packing insert layer 12 starts to be worn, so that diamond is exposed (exposed) to crush the object, during the object crushing process, the diamond is continuously worn, meanwhile, broken fragments continuously abrade the matrix 11, so that the diamond is guaranteed to have sufficient exposed, the diamond automatically falls off when the diamond is abraded until the packing insert of the matrix 11 is not firm, and new diamond is exposed in the matrix 11, and the object is continuously crushed. Therefore, the cutting efficiency of the diamond circular saw blade and the adaptability to the material of objects are greatly improved, and the working efficiency and the service life of the saw blade are greatly improved.

It will be understood that the utility model has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the utility model.
