[0004] In existing technologies, the saw blade body and the saw tooth assembly are mostly made by welding or integral molding. For welded saw blades, the saw teeth need to be removed when they are damaged and replaced, which is inefficient and labor-intensive. For integral molding, the saw teeth and the saw blade body are made of different materials, resulting in high overall replacement losses and low utilization.

[0005] Therefore, we propose a bimetallic band saw blade. Utility Model Content

[0028] The replacement structure is set at the bottom of the backing material 10 for sawing materials.

[0029] like Figure 2 and Figure 3As shown in Embodiment 1, the replacement structure is a detachable saw blade 20 installed at the bottom of the backing material 10. The bottom of the saw blade 20 has a cutting surface. The saw blade 20 is engaged with the slot 11. The saw blade 20 forms a cutting surface at the bottom of the backing material 10 with the same length as the backing material 10. The replacement structure also includes a first locking block 21. Several first locking blocks 21 are fixedly provided on the side wall of the saw blade 20. The first locking blocks 21 are engaged with the slot 11. The first locking blocks 21 are trapezoidal blocks. The first locking blocks 21 are fixedly connected to the saw blade 20. The first locking blocks 21 and the slot 11 are in clearance fit. The replacement decoupling strand also includes a groove 22. The saw blade 20 forms a U-shaped groove. A groove 22 is opened on both sides of the inner wall of the saw blade 20. The grooves 22 are radially distributed along the saw blade 20 and penetrate the saw blade 20. Several saw blade bodies 23 are fixedly provided at the bottom of the saw blade 20. The saw blade 20 forms a cutting surface through the multiple saw blade bodies 23.

[0030] In this solution, a serrated band 20 of the same length as the backing material 10 is provided. The serrated band 20 is deformable, and the first locking block 21 on the side wall of the serrated band 20 is used to fix and limit the serrated band 20 by the deformation and reset of the serrated band 20, so that the first locking block 21 can be inserted into the slot 11. When removing the serrated band 20, a rectangular column adapted to the groove 22 is inserted into the groove 22, and the side wall of the serrated band 20 is pried to deform, so that the first locking block 21 can be disengaged from the slot 11. The disassembly and assembly are simple and quick. With the detachable serrated band 20, functional partitioning and quick replacement can be realized. The serrated band 20 and the serrated body 23 are integrally formed. The serrated body 23 is made of high-speed steel. By setting the detachable serrated band 20, different tooth pitches and different angles of the serrated body 23 can be selected according to different cutting materials to meet the cutting needs of different materials and improve the utilization rate of high-speed steel.

[0031] like Figure 4 and Figure 5 As shown, the replacement structure is a saw tooth module 30 that can be detachably installed at the bottom of the backing material 10. The bottom of the saw tooth module 30 has a cutting surface. The saw tooth module 30 is engaged with the slot 11. Multiple saw tooth modules 30 form a cutting surface at the bottom of the backing material 10 with the same length as the backing material 10. The replacement structure also includes a second saw tooth 31, a second locking block 32 and a drop groove 33. Several second saw teeth 31 are fixedly installed at the bottom of the saw tooth module 30. The top of the saw tooth module 30 is provided with a slot that adapts to the backing material 10. Several second locking blocks 32 are fixedly installed on the inner side wall of the slot. The second locking blocks 32 are engaged with the slot 11. Several drop grooves 33 are also opened at the top of the saw tooth module 30. The saw tooth module 30 forms a groove with a U-shaped cross section. Several groups of second locking blocks 32 are provided on the inner side wall of the saw tooth module 30. The second locking blocks 32 are adapted to the slot 11. A drop groove 33 is provided between two second locking blocks 32 in the same group. The drop groove 33 is a rectangular groove.

[0032] In this solution, as an optimization and supplement to the above solution, the saw tooth module 30 is made of high-speed steel, and multiple saw tooth modules 30 can be set. The tooth pitch and tooth depth of the saw teeth 31 at the bottom of the saw tooth module 30 can be set to different values. Multiple saw tooth modules 30 jointly construct a cutting surface. The backing material 10 is inserted into the slot at the top of the saw tooth module 30, and the radial limit of the saw tooth module 30 is achieved by the second locking block 32 engaging in the slot 11. A flathead screwdriver can be inserted into the lower groove 33 to pry the saw tooth module 30 to deform it, thereby causing the second locking block 32 to engage. 2.

The saw tooth module 30 located at the end of the backing material 10 can be equipped with a saw tooth 31 with a smaller tooth pitch to facilitate start-up, while the saw tooth module 30 located in the middle position can be equipped with a saw tooth 31 with a larger tooth pitch to improve the sawing speed. The design of disassembling and assembling multiple saw tooth modules 30 has two advantages: first, it is convenient to replace the partially damaged saw tooth module 30 individually; second, it is possible to customize the sawing surface according to the needs, making it more flexible in use.

[0033] The working principle of this utility model is as follows: The sawtooth strip 20 is deformable, and the first locking block 21 on the side wall of the sawtooth strip 20 is used to fix and limit the sawtooth strip 20 by utilizing the deformation and reset of the sawtooth strip 20 to allow the first locking block 21 to engage in the slot 11. When removing the sawtooth strip 20, a rectangular column adapted to the groove 22 is inserted into the groove 22, and the side wall of the sawtooth strip 20 is pried to deform, causing the first locking block 21 to disengage from the slot 11. Multiple sawtooth modules 30 are provided. The tooth pitch and tooth depth of the bottom saw teeth 31 can be set to different values. Multiple saw tooth modules 30 are used to build a cutting surface. The backing material 10 is inserted into the slot at the top of the saw tooth module 30. The second locking block 32 is inserted into the slot 11 to achieve radial positioning of the saw tooth module 30.
