Technical Field

[0001] The utility model relates to the technical field of saw blades, and particularly relates to a multi-blade saw blade. Background Art

[0002] Saw blades are collectively referred to as thin circular tools for cutting solid materials, mainly divided into diamond saw blades for stone cutting; high-speed steel saw blades (without inlaid cemented carbide tool heads) for cutting metal materials; cemented carbide saw blades for cutting solid wood, furniture, artificial boards, aluminum alloys, aluminum profiles, radiators, plastics, plastic-steel, etc. A multi-blade saw blade refers to a saw blade used by installing multiple blades together, generally mainly alloy saw blades.

[0003] Currently, when using saw blades, there is a lack of a thickness adjustment mechanism. Usually, the size of the saw blade is fixed, and it is difficult to adjust the thickness of the saw blade used in combination according to actual usage needs, resulting in a relatively fixed and single usage effect during actual use. Moreover, when local damage occurs, it is necessary to replace the whole, which not only affects the usage effect but also increases the usage cost. Therefore, a multi-blade saw blade is proposed to facilitate adding an auxiliary thickness adjustment mechanism and adapting to different usage scenarios and requirements by using a splicing and combination method, improving the flexibility of use. Moreover, when local single saw blades are damaged, it is not necessary to replace the whole, thereby reducing the usage cost and improving the usage effect. Summary of the Invention

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] In order to facilitate the addition of auxiliary thickness adjustment mechanisms, the splicing combination method is used to adapt to different usage scenarios and usage requirements, thereby improving the usage effect, such as Figures 1-4 As shown, a multi-blade saw blade of the utility model comprises a disc assembly 1, an outer ring assembly 2 and a positioning assembly 3. The outer ring assembly 2 is fixedly arranged on the periphery of the disc assembly 1, and the positioning assembly 3 is arranged inside the disc assembly 1;

[0030] The disc assembly 1 includes a disc 101, the outer ring assembly 2 includes an outer ring 201, and the disc 101 is connected to the outer ring 201 by welding. The positioning assembly 3 includes an insertion rod 301, both ends of the insertion rod 301 are provided with fixing caps 302, and the fixing caps 302 are connected to both ends of the insertion rod 301 by threads.

[0031] When in use, an auxiliary thickness adjustment mechanism can be added through the disc 101, the outer ring 201, the long rod 301 and the fixing cap 302, and the flexibility of the saw blade can be improved by using a combined connection method to adapt to different usage scenarios and usage requirements.

[0032] In order to improve the stability of the saw blade, for example, Figure 3 ,Figure 5 As shown in the figure, the utility model further includes that a hollow part 105 is formed inside the disc 101, a reinforcing rod 106 is connected inside the hollow part 105 by welding, and a spiral blade 107 is connected around the reinforcing rod 106 by welding.

[0033] During use, through the hollow part 105, the reinforcing rod 106 and the spiral blade 107, an auxiliary flow guiding and heat dissipating mechanism can be added, and while the saw blade is working, the heat generated inside can be taken out, playing an auxiliary role in heat dissipation and temperature reduction, thereby improving the stability of use.

[0034] Exemplarily, as Figure 3 、 Figure 4 As shown in the figure, the utility model further includes that a gasket 303 is sleeved on the periphery of the inserting rod 301 and inside the fixing cap 302. External threads 304 are provided at both ends of the inserting rod 301, and the fixing cap 302 is threadedly connected to the inserting rod 301 through the external threads 304. A groove 103 corresponding to the fixing cap 302 is formed on the surface of the disc 101, and a through hole 104 corresponding to the inserting rod 301 is formed inside the groove 103.

[0035] During use, the gasket 303 is convenient for improving the stability of the fixing cap 302 in use, the external threads 304 are convenient for the fixing cap 302 to be threadedly connected to the inserting rod 301, and the groove 103 and the through hole 104 are convenient for installing the positioning component 3.

[0036] Exemplarily, as Figure 5 As shown in the figure, the utility model further includes that a chip discharging hole 102 is formed on the surface of the disc 101, a flow guiding hole 4 is formed on the surface of the disc 101 and around the chip discharging hole 102, and the flow guiding hole 4 communicates with the hollow part 105.

[0037] During use, the chip discharging hole 102 communicates with the hollow part 105 through a reserved hole. Through the chip discharging hole 102 and the flow guiding hole 4, it is convenient to communicate with the hollow part 105, so that external air flow or coolant can enter the inside of the saw blade to take away heat.

[0038] Exemplarily, as Figure 2 As shown in the figure, the utility model further includes that a convex block 202 is arranged on the inner side of the outer ring 201, and saw teeth 203 are arranged on the periphery of the outer ring 201.

[0039] During use, through the convex block 202, it is convenient for the outer ring 201 to be clamped to the disc 101, and through the saw teeth 203, it is convenient for sawing.

[0041] During use, the notch 108 facilitates the engagement of the protrusion 202 of the outer ring 201 to complete the auxiliary limit treatment, thereby improving the convenience and stability of the welding operation. The mounting hole 5 facilitates connection to a driving device for use.

[0042] When this utility model is in use, first, the operator engages the protrusion 202 of the outer ring 201 into the corresponding notch 108 of the disc 101, and then performs welding connection treatment on the disc 101 and the outer ring 201. Before actual use, according to the use scenario and requirements, the insertion rod 301 can be passed through the through hole 104 of the groove 103, and then the gasket 303 is sleeved on both ends of the insertion rod 301. The fixing cap 302 is screwed to threadedly connect the insertion rod 301 to perform limit fixing treatment on multiple welded discs 101. Thus, by using the combined splicing method, the flexibility of the saw blade during use is improved, while adapting to different use scenarios and requirements. Moreover, after use, according to the degree of wear, local saw blades can be disassembled and replaced, which can replace the traditional method of overall replacement, reduce the use cost, and make the use more reasonable and reliable.

[0043] During the working process of the saw blade, external air flow or coolant can enter the hollow part 105 from the reserved hole or the diversion hole 4 of the chip removal hole 102, taking out the heat generated during the working of the saw blade, achieving the effect of auxiliary heat dissipation. Moreover, by utilizing the spiral structures of the reinforcing rod 106 and the spiral blade 107, the heat dissipation effect can also be improved, thereby enhancing the stability of the saw blade during use and being beneficial to extending the service life.
