[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A matrix-filled circular saw blade comprises a saw blade body 1, saw teeth 2 are distributed on the outer circumference of the saw blade body 1, annular grooves 3 are provided on the top and bottom of the saw blade body 1, and connecting grooves 4 in an annular array are provided on the inner wall of the annular groove 3. The annular groove 3 and the connecting grooves 4 are filled with wear-resistant materials, and the saw blade body 1 is made of cemented carbide.

[0025] A heat-conducting protrusion component 5 in an annular array is fixedly connected in the annular groove 3, and the heat-conducting protrusion component 5 and the connecting slot 4 are arranged alternately. An annular cover plate 6 is arranged on the top and bottom of the saw blade body 1. The annular cover plate 6 is adapted to the annular groove 3. The annular cover plate 6 is provided with matching slots 7 in an annular array. The matching slots 7 are used to clamp the heat-conducting protrusion component 5 together when the annular cover plate 6 is located in the annular groove 3.

[0026] like Figure 1 and Figure 3 The saw blade body 1 is a circular saw blade made of carbide material, which can improve the strength of the saw blade body 1. The wear-resistant material is compacted in the annular groove 3 and the connecting groove 4 by a hot press. The sum of the thickness of the wear-resistant material in the annular groove 3 and the thickness of the annular cover plate 6 is consistent with the depth of the annular groove 3, so that the annular cover plate 6 is located.

[0027] A center hole 8 is formed at the center of the saw blade body 1 , and transmission holes 9 are formed around the center hole 8 on the saw blade body 1 .

[0028] like Figure 1 and Figure 3 The central hole 8 and the transmission hole 9 facilitate the connection between the saw blade body 1 and the external device, and the saw blade body 1 can be driven to rotate by the external device.

[0029] The heat-conducting protrusion 5 is provided with heat dissipation holes 10 , and the saw blade body 1 is provided with chip removal grooves 11 in a ring array.

[0030] like Figure 1 and Figure 3 The heat-conducting protrusion 5 can be used to conduct heat on the saw blade body 1, and the heat dissipation holes 10 allow air flow to pass through the heat-conducting protrusion 5, thereby improving the heat dissipation capacity of the heat-conducting protrusion 5 and the saw blade body 1.

[0031] The depth of the annular groove 3 is one third of the thickness of the saw blade body 1 , and the outer surface of the heat-conducting protrusion 5 and the outer surface of the saw blade body 1 are located in the same horizontal plane.

[0032] like Figure 1 , Figure 2 and Figure 3 The thickness of the annular groove 3 is only one-third of the saw blade body 1, so that the saw blade body 1 can still remain connected in the annular groove 3, thereby improving the strength of the saw blade body 1. The number of heat-conducting protrusions 5 is consistent with the number of matching slots 7, so that each heat-conducting protrusion 5 can be inserted into a matching slot 7.

[0033] A thickened ring 12 is fixedly connected to the center of the saw blade body 1 , and a rubber protective inner pad 13 is fixedly connected to the inner surface of the center hole 8 .

[0034] like Figure 1 and Figure 3 The thickened ring 12 can improve the strength of the center of the saw blade body 1, which is convenient for connecting the saw blade body 1 with external equipment. The rubber protective inner pad 13 can prevent the main shaft of the external equipment from directly contacting the inner wall of the center hole 8 and causing mechanical collision when passing through the center hole 8, thereby providing flexible protection for the connection of the saw blade body 1.

[0035] The outer circumference of the annular cover plate 6 is fixedly connected to a first fixing plate 14 in an annular array, and the saw blade body 1 is provided with a first positioning groove 15 used in conjunction with the first fixing plate 14. The inner circumference of the annular cover plate 6 is fixedly connected to a second fixing plate 16 in an annular array, and the saw blade body 1 is provided with a second positioning groove 17 used in conjunction with the second fixing plate 16.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4After the wear-resistant material is filled in the annular groove 3 and the connecting groove 4 of the saw blade body 1, the annular cover plate 6 can be attached to the outer side of the wear-resistant material in the annular groove 3, and the heat-conducting protrusion 5 can be inserted into the matching groove 7. The outer surface of the annular cover plate 6 is located in the same plane as the outer surface of the saw blade body 1. Then, the first fixing plate 14 is fixed (welded or bonded) to the first positioning groove 15, and the second fixing plate 16 is fixed (welded or bonded) to the second positioning groove 17 to position the annular cover plate 6. At this time, the filled wear-resistant material is located on the inner side of the annular cover plate 6 and will not fall off from the annular groove 3.

[0037] Compared with the related art, the matrix-filled circular saw blade provided by the utility model has the following beneficial effects:

[0038] The utility model can reduce the noise of the saw blade body 1 and increase the service life of the saw blade body 1 by filling the saw blade body 1 with wear-resistant material, and at the same time fix two annular cover plates 6 on the saw blade body 1, and the annular cover plates 6 cover the outer side of the wear-resistant material filled on the saw blade body 1, so as to prevent the filled wear-resistant material from falling off, so that the wear-resistant material can be stably maintained in the saw blade body 1, and at the same time, the heat-conducting protrusion part 5 is inserted into the matching groove 7, and cooperates with the heat dissipation hole 10 on the heat-conducting protrusion part 5 to improve the heat dissipation capacity of the saw blade body 1, thereby further improving the service life of the saw blade body 1.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
