Description

Technical Field

[0001] This utility model belongs to the field of diamond saw blade technology, and particularly relates to an impact-resistant diamond saw blade. Background Technology

[0002] Diamond saw blades have superior cutting performance and are convenient and efficient. They are not only used in the processing of stone and superhard materials, but also increasingly widely used in the construction field, such as the renovation and demolition of various roads (airport runways, asphalt pavements, etc.) and buildings.

[0003] The sawing process of diamond saw blades is an intermittent grinding process. The high-speed rotation of the saw blade, the flow of rock chips, and the impact when the cutter head enters the blade will all cause deformation of the saw blade base. The impact on the cutter head will wear it down to the rounded corners, or even cause the teeth to fall out. Utility Model Content

[0004] The purpose of this invention is to provide an impact-resistant diamond saw blade to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: An impact-resistant diamond saw blade includes a base, with protrusions provided at the edges of both sides of the base. Multiple U-shaped openings arranged in a circumferential array and penetrating the protrusions are provided at the edges of the base surface. A fan-shaped block is formed between every two adjacent U-shaped openings. A cutting head is provided at the edge of each fan-shaped block. An elastic tongue is provided on one side of each U-shaped opening. A cavity is provided inside each fan-shaped block, and a vent hole penetrating the cavity is provided on the surface of the protrusion.

[0006] Preferably, the tab has an annular structure, and the surface of the tab protrudes from the surface of the substrate.

[0007] Preferably, the elastic tongue is welded and fixed to the side wall of the U-shaped opening, and there is a gap between the elastic tongue and the cutting head.

[0008] Preferably, both ends of the cavity are connected to a U-shaped opening.

[0009] Preferably, the vent hole has an elongated oval structure and is located at the center of the cavity.

[0010] Preferably, the surface of the protrusion is coated with a melt-blown layer.

[0011] The impact-resistant diamond saw blade of this invention has the following advantages: 1. This utility model uses an elastic tongue welded to the side wall of each U-shaped opening to buffer the impact of rock debris flow on the saw head when the saw blade rotates at high speed, reduce the stress deformation of the base body, greatly reduce the wear of the saw head end, and thus improve the impact resistance of the saw blade.

[0012] 2. During sawing, the surrounding airflow enters the cavity through the vent hole, and the centrifugal force caused by the rotation of the saw blade causes the airflow to be discharged from the U-shaped opening. This strong airflow generated by the rotation of the saw blade can effectively cool the cutting head on the outer circle of the saw blade, thereby improving the cooling and heat dissipation effect of the saw blade. In addition, the setting of the vent hole can also buffer the impact on the cutting head and the base.

[0013] 3. By setting the tabs, the surface of the substrate will not directly contact the object during sawing. Instead, the tabs will contact the object, which provides good protection for the substrate. Furthermore, a layer of WC-Co as the main component is sprayed onto the surface of the tabs using a low-temperature spraying method. This method can prevent substrate wear and improve the rigidity of the saw blade. Attached Figure Description

[0022] To better understand the purpose, structure, and function of this utility model, the following detailed description of an impact-resistant diamond saw blade, in conjunction with the accompanying drawings, is provided.

[0023] like Figure 1-3As shown, this utility model discloses an impact-resistant diamond saw blade, comprising a base 1. Both sides of the base 1 have protrusions 2 at their edges. The protrusions 2 are annular in structure, and their surfaces protrude beyond the surface of the base 1. The protrusions 2 ensure that during sawing, the surface of the base 1 does not directly contact the object; instead, the protrusions 2 contact the object, providing excellent protection for the base 1. The surface of the protrusions 2 is coated with a sprayed layer. A sprayed layer with WC-Co as the main component is applied to the surface of the protrusions 2 using a low-temperature spraying method. This method not only prevents wear on the base 1 but also improves the rigidity of the saw blade. Multiple U-shaped openings 3 arranged in a circumferential array and penetrating the protrusion 2 are provided at the surface edge of the substrate 1, and a fan-shaped block 4 is formed between each two adjacent U-shaped openings 3. A blade head 5 is provided at the edge of each fan-shaped block 4. An elastic tongue 6 is provided on one side of each U-shaped opening 3. The elastic tongue 6 is welded and fixed to the side wall of the U-shaped opening 3, and there is a gap between the elastic tongue 6 and the blade head 5. By welding an elastic tongue 6 to the side wall of each U-shaped opening 3, the impact of rock debris flow on the blade head 5 when the saw blade rotates at high speed can be buffered, the deformation of the substrate under stress 1 can be reduced, the wear of the blade head 5 can be greatly reduced, and the impact resistance of the saw blade can be improved.

[0024] Each sector block 4 has an internal cavity 7, and the surface of the protrusion 2 has a vent hole 8 that penetrates the cavity 7. Both ends of the cavity 7 are connected to the U-shaped opening 3. The vent hole 8 is an elongated oval structure and is located in the center of the cavity 7. During sawing, the surrounding airflow enters the cavity 7 through the vent hole 8, and the centrifugal force caused by the rotation of the saw blade causes the airflow to be discharged from the U-shaped opening 3. This strong airflow generated by the rotation of the saw blade can effectively cool the cutting head 5 on the outer circle of the saw blade, thereby improving the cooling and heat dissipation effect of the saw blade. In addition, the vent hole 8 can also buffer the impact on the cutting head 5 and the base 1.

[0025] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model.
