Description

Technical Field

[0001] The utility model relates to the technical field of fine steel stone cutting blades, in particular to a diamond cutting blade with good heat dissipation. Background Art

[0002] Diamond cutting is a cutting tool widely used in the processing of hard and brittle materials such as stone, concrete, prefabricated panels, new and old roads, and ceramics. The diamond cutting blade is mainly composed of two parts: a substrate and a cutter head. The substrate is the main supporting part for bonding the cutter head, and the cutter head is the part that performs cutting during use. The cutter head can perform cutting because it contains diamond. Diamond, as the hardest substance currently available, rubs and cuts the processed object in the cutter head. After searching, a Chinese patent with publication number CN216230139U discloses a diamond cutting blade with high heat dissipation, including a substrate and a plurality of diamond cutter heads arranged on the outer circumference of the substrate. The thickness of the diamond cutter heads is greater than the thickness of the substrate. There are inclined gaps between the plurality of diamond cutter heads. The center of the substrate has a mounting hole. Both side end faces of the substrate have a plurality of evenly distributed convex ribs. One end of the convex rib extends to the mounting hole, and the other end of the convex rib extends to the adjacent two metal The gap between the diamond bits; the base also has a plurality of heat dissipation holes and a plurality of chip removal holes with equal circumference distribution, the plurality of chip removal holes are placed on the inner side of the plurality of heat dissipation holes, the chip removal holes and the heat dissipation holes are staggered in sequence, the heat dissipation holes are long strip raindrop-shaped structures, a plurality of heat dissipation holes and a plurality of chip removal holes are arranged on the base, which not only realizes the heat dissipation of the base, but also facilitates the discharge of debris and powder during the cutting process, the heat dissipation holes and the chip removal holes adopt a staggered structure, which ensures the heat dissipation of the base while avoiding the concentration of holes and affecting the structural strength of the base, a plurality of convex ribs are arranged on the base, which further improves the structural strength of the base, but it mainly dissipates heat for the base, however, during the cutting process, the temperature of the diamond bit is the highest, although the diamond bit will still be cooled while the base is cooled, but the heat dissipation effect on the diamond bit that causes the heat is low, so the overall heat dissipation effect still needs to be improved.

[0019] 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 in 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.

[0020] Example:

[0021] See also Figure 1-3 A diamond cutting blade with good heat dissipation comprises a diamond cutting blade body, the diamond cutting blade body comprises a substrate and a plurality of diamond bits 1 arranged on the outer circumference of the substrate, a plurality of heat dissipation grooves 5 are circumferentially opened on the substrate, the plurality of heat dissipation grooves 5 are connected with the plurality of diamond bits 1 one by one, a heat conduction ring strip 6 in contact with the diamond bits 1 is fixedly installed in the heat dissipation groove 5, a guide groove 7 is opened on the heat conduction ring strip 6, further, the heat dissipation groove 5 and the guide groove 7 are both streamlined and have a guide curvature, so as to improve the flow of air circulation during cutting and improve the heat dissipation effect.

[0022] The position between two adjacent heat dissipation grooves 5 on the substrate is set as a connecting strip 3, and each diamond bit 1 is placed and connected between two adjacent connecting strips 3. By placing each diamond bit 1 between two adjacent connecting strips 3, the tightness of the connection between the substrate and multiple diamond bits 1 is further improved, and the stability of the overall structure is improved.

[0023] A chip guide gap 2 is provided between two adjacent diamond bits 1. The chip guide gap 2 extends to the base and is connected to an arc groove provided on the connecting strip 3. Both sides of the arc groove are provided with connecting surfaces 4 fixedly connected to the diamond bit 1. By providing the chip guide gap 2, it is convenient to guide the chips out of the cutting seam during the cutting process. By providing the arc groove, the smoothness of the chip guiding is improved.

[0024] A fixed platform 8 is provided in the middle of the base body, and a central positioning hole 9 and side holes 10 are provided on the fixed platform 8. The diamond cutting blade body is turned over by the fixed platform 8 for installation before cutting. The central positioning hole 9 and multiple side holes 10 are used to improve the stability of the installation.

[0025] Both sides of the substrate are provided with debris guide surfaces staggered from the end faces of the diamond bit 1 . By providing both sides of the substrate with debris guide surfaces staggered from the end faces of the diamond bit 1 , the discharge of debris is further facilitated.

[0026] Both sides of the heat-conducting ring strip 6 are flush with the end face of the diamond cutter head 1. By making both sides of the heat-conducting ring strip 6 flush with the end face of the diamond cutter head 1, it is convenient to increase the contact area with the diamond cutter head 1 and increase the heat conduction effect. At the same time, it also plays a guiding and supporting role in the cutting process. Furthermore, the heat-conducting ring strip 6 is fixedly connected to the diamond cutter head 1 to further increase the stability of the structure.

[0027] When in use, the diamond cutting blade body is mounted on a cutting tool, and the diamond cutting blade body is driven to rotate for cutting. When cutting, heat is generated on the diamond bit 1 due to frictional heat, and the heat is transferred to the substrate and the heat-conducting ring strip 6. As the cutting proceeds, the guide groove 7 transmits the air on one side of the diamond cutting blade body to the other side. At the same time, the heat at the heat-conducting ring strip 6 flows out smoothly through the guide groove 7. The heat on the diamond bit 1 and the substrate is continuously transmitted to the heat-conducting ring strip 6, and as the cutting proceeds, it is continuously diverted out through the guide groove 7, so that both the substrate and the diamond bit 1 achieve a higher heat dissipation effect.
