Description

Technical Field

[0001] This utility model relates to the field of saw blade technology, and in particular to a saw blade for multi-tooth saw blades. Background Technology

[0002] Multi-tooth saw blades, also known as multi-blade saw blades, are cutting tools composed of multiple straight saw blades. They are mainly used in the wood processing industry. After a period of use, the teeth on some of the existing multi-tooth saw blades will become damaged, and the damaged saw blades need to be replaced. However, when replacing a damaged saw blade, it is necessary to disassemble the other peripheral saw blades in order to replace the damaged one, which is very time-consuming. Utility Model Content

[0003] The purpose of this invention is to provide a saw blade for multi-tooth saw blades, thereby solving the aforementioned problems existing in the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A saw blade for multi-tooth saw blades includes a saw blade body, an outer mounting ring on the outer side of the saw blade body, a saw blade sleeve on the mounting ring, a threaded hole on the mounting ring, and a countersunk hole on the saw blade corresponding to the threaded hole; it also includes a bolt, which passes through the countersunk hole and is threadedly connected to the threaded hole to fix the saw blade to the saw blade body.

[0006] The beneficial effects of this utility model are: when the saw teeth are damaged and need to be replaced, the corresponding saw blade can be replaced simply by using the bolts on the corresponding saw blade, without disassembling the main body of the saw blade, and therefore without disassembling the outer saw blade, which can greatly reduce the replacement time.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the saw blade is fan-shaped, and multiple saw blades are connected end to end to form a ring.

[0009] The further beneficial effect of adopting the above is that by forming a ring with multiple saw blades, a circular array of saw teeth is achieved on the outer side of the saw blade body, thus achieving efficient cutting of wood.

[0010] Furthermore, each of the saw blades is symmetrically provided with two countersunk holes.

[0011] Furthermore, it also includes a limiting block, which is disposed at one end of the saw blade near the saw blade body. A limiting groove adapted to the limiting block is opened on the outer side of the saw blade body, and the limiting block is inserted into the limiting groove.

[0012] Furthermore, the saw blade body is provided with circular heat dissipation holes and arc-shaped heat dissipation holes arranged in a circumferential array around the mounting hole, and the arc-shaped heat dissipation holes are located outside the circular heat dissipation holes.

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0019] Example 1

[0020] like Figures 1 to 3 As shown, a multi-tooth saw blade includes a saw blade body 1, an mounting ring 12 is provided on the outer side of the saw blade body 1, a saw blade 2 is sleeved on the mounting ring 12, a threaded hole 3 is provided on the mounting ring 12, and a countersunk hole 5 is provided on the saw blade 2 corresponding to the threaded hole 3; it also includes a bolt 4, which passes through the countersunk hole 5 and is threadedly connected to the threaded hole 3 to fix the saw blade 2 on the saw blade body 1.

[0021] When the saw teeth are damaged and need to be replaced, the corresponding saw blade 2 can be replaced simply by using the bolt 4 of the corresponding saw blade 2. There is no need to disassemble the saw blade body 1, and therefore no need to disassemble the outer saw blade, which can greatly reduce the replacement time.

[0022] Example 2

[0023] like Figure 1 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0024] The saw blade 2 is fan-shaped, and multiple saw blades 2 are connected end to end to form a ring. By forming a ring with multiple saw blades 2, the saw teeth are arrayed on the outer circumference of the saw blade body 1, thus achieving efficient cutting of wood.

[0025] Example 3

[0026] like Figure 2 and Figure 3 As shown, this embodiment is a further improvement on embodiment 2, as detailed below:

[0027] Two countersunk holes 5 are symmetrically arranged on each saw blade 2 to ensure stable installation of the saw blade 2 and prevent damage caused by uneven force during use.

[0028] Example 4

[0029] like Figure 2 and Figure 3 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0030] It also includes a limiting block 7, which is set at one end of the saw blade 2 near the saw blade body 1. A limiting groove 6 adapted to the limiting block 7 is opened on the outer side of the saw blade body 1. The limiting block 7 is inserted into the inside of the limiting groove 6. By inserting the limiting block 7 into the limiting groove 6, the saw blade 2 is limited, so that the countersunk hole 5 on the saw blade 2 corresponds to the threaded hole 3, which facilitates the installation of the saw blade 2.

[0031] Example 5

[0032] like Figure 2 As shown, this embodiment is a further improvement on any one of embodiments 1 to 4, as detailed below:

[0033] The saw blade body 1 has circular heat dissipation holes 8 and arc-shaped heat dissipation holes 9 arranged in a circular array around the mounting hole 11. The arc-shaped heat dissipation holes 9 are located outside the circular heat dissipation holes 8. The circular heat dissipation holes 8 and arc-shaped heat dissipation holes 9 dissipate heat from the saw blade body 1 to prevent it from being damaged due to excessive temperature.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
