[0033] Example 1

[0034] like Figure 1-4 As shown, the present invention proposes a metal saw blade straightening device, including a worktable 1, a straightening roller 4, a fixing plate 10, a drive assembly and a pressing assembly;

[0035] The fixing plate 10 is installed on one side of the top of the workbench 1. The side of the fixing plate 10 is provided with a plurality of positioning rollers 5 for limiting the position of the saw blade in use. The rotating shaft of the positioning rollers 5 extends through the workbench 1 to the bottom of the workbench 1.

[0036] The pressing assembly is located on the side of the positioning roller 5 and is arranged in cooperation with multiple positioning rollers 5;

[0037] There are multiple straightening rollers 4, which are respectively set on the fixed plate 10 and the pressing assembly and arranged symmetrically. One end of the straightening roller 4 is provided with an adjustment assembly for adjusting the position of the straightening roller 4 on the worktable 1 during use.

[0038] The drive assembly is located below the worktable 1 and is connected to the rotating shafts of multiple positioning rollers 5.

[0039] In an optional embodiment, the top of the worktable 1 is provided with a plurality of bosses 9, which are bolted to the worktable 1 (not shown in the figure). The upper end face of the bosses 9 is arranged to match the lower end face of the pressure roller 3 and the positioning roller 5, so as to support the saw blade during use, so that the saw blade remains stable during the correction process and avoids the end from shifting downward due to gravity.

[0040] In an optional embodiment, the side of the boss 9 is provided with a notch 18, which is arranged with the end dimensions of the pressure roller 3 and the positioning roller 5. It is used to place the ends of the pressure roller 3 and the positioning roller 5 during use, so that the pressure roller 3 can be rolledly connected to the positioning roller 5 inside the notch 18, thereby achieving clamping of the saw blade and improving the stability of the saw blade during processing.

[0041] In an optional embodiment, a slide 17 is provided between two adjacent bosses 9. The size of the slide 17 is adapted to the width of the straightening roller 4. It is used to align and position the straightening roller 4 in the slide 17 during use, ensuring that multiple straightening rollers 4 remain parallel and have consistent spacing during installation. At the same time, it allows the two symmetrically arranged straightening rollers 4 to adjust their positions inside the slide 17, so that the straightening roller 4 can adjust the deformation of the saw blade inside the slide 17, thereby meeting the processing requirements of saw blades of different specifications.

[0042] In this embodiment, the position of the straightening rollers 4 on the pressing assembly and the fixing plate 10 is adjusted by the adjusting component, so that the center position of the two straightening rollers 4 when clamping the saw blade is offset from the center position of the pressing assembly and the positioning rollers 5 when clamping the saw blade. At the same time, the pressing assembly is moved towards the positioning rollers 5, so that the saw blade is pressed onto the positioning rollers 5, and the positioning rollers 5 cooperate with the pressing assembly to clamp the saw blade. Then, the pressing assembly drives the straightening rollers 4 to move towards the straightening rollers 4 on the fixing plate 10, thereby limiting the position of the saw blade. The driving component drives the multiple positioning rollers 5 to rotate synchronously. The positioning roller 5 works in conjunction with the pressing assembly to clamp and convey the saw blade. During the conveying process, when the saw blade passes through the area between the two straightening rollers 4, the straightening rollers 4 apply pressure to the saw blade, causing it to deform in that area and be conveyed between the positioning roller 5 and the pressing assembly to achieve reset deformation. The straightening rollers 4, the positioning roller 5, and the pressing assembly then deform the saw blade multiple times to complete the saw blade straightening. At the same time, the adjusting assembly finely adjusts the center position between the two straightening rollers 4 so that the center position can be set according to the actual thickness of the saw blade, thereby adapting to saw blades of different thicknesses and improving the applicability range.

[0043] Example 2

[0044] like Figure 1 As shown, the present invention proposes a metal saw blade straightening device. Compared with the first embodiment, the difference in this embodiment is that the pressing component includes a mounting plate 2, a pressure roller 3, and a linear driver 8.

[0045] The linear actuator 8 is mounted on the top of the worktable 1 and its extended end is arranged vertically toward the side of the fixed plate 10. The linear actuator 8 is one of a cylinder, a hydraulic cylinder, and an electric telescopic rod.

[0046] Mounting plate 2 is installed at the output end of linear driver 8;

[0047] The pressure roller 3 is installed on the side of the mounting plate 2, and the pressure roller 3 and the positioning roller 5 are arranged in a one-to-one correspondence.

[0048] In this embodiment, pressure rollers 3 are installed at equal intervals on the side of mounting plate 2, and pressure rollers 3 and positioning rollers 5 are arranged in a one-to-one correspondence, so that linear driver 8 drives pressure rollers 3 to move towards positioning rollers 5 through mounting plate 2, thereby achieving clamping of saw blade.

[0049] Example 3

[0050] like Figure 3 As shown, the present invention proposes a metal saw blade straightening device. Compared with the first embodiment, the difference in this embodiment is that the adjusting component includes a slide rod 6, an adjusting bolt 7, and an internally threaded tube 13.

[0051] There is at least one slide bar 6. The slide bar 6 is installed on the top of one end of the straightening roller 4. The slide bar 6 passes through the mounting plate 2 or the fixing plate 10 and is slidably connected to it.

[0052] The adjusting bolt 7 is located at the middle of one end of the straightening roller 4;

[0053] The internally threaded tube 13 is sleeved on the outside of the adjusting bolt 7 and threadedly connected to the adjusting bolt 7. The internally threaded tube 13 is fixedly connected to the mounting plate 2 or the fixing plate 10.

[0054] In this embodiment, the slide rod 6 is arranged by passing through the mounting plate 2 and the fixing plate 10 at one end, so that the slide rod 6 supports and guides the position of the straightening roller 4, ensuring that the straightening roller 4 remains stable during the adjustment process and can move along the set trajectory. At the same time, the position of the end of the adjusting bolt 7 can be adjusted by rotating the adjusting bolt 7 inside the internal thread tube 13, thereby realizing flexible adjustment of the position of the straightening roller 4 and adapting to saw blades of different specifications.

[0055] Example 4

[0056] like Figure 3 As shown, the present invention proposes a metal saw blade straightening device, which, compared with Embodiment 1, further includes a fixing bolt 14, a connecting block 15, and a limiting plate 16.

[0057] The connecting block 15 is located at the end of the adjusting bolt 7 and is connected to the adjusting bolt 7 via the fixing bolt 14;

[0058] The limiting plate 16 is wrapped around the outside of the connecting block 15 and connected to the straightening roller 4.

[0059] In this embodiment, the connecting block 15 is installed at the end of the adjusting bolt 7 by fixing bolt 14, and the limiting plate 16 is wrapped around the outside of the connecting block 15 and connected to the straightening roller 4, so that the limiting plate 16 limits the position of the connecting block 15. Thus, when the adjusting bolt 7 rotates to adjust the position inside the internal thread tube 13, the adjusting bolt 7 drives the connecting block 15 to rotate inside the limiting plate 16, and the straightening roller 4 moves with the position adjustment of the adjusting bolt 7, thereby achieving precise adjustment of the saw blade clamping position and improving the adjustment convenience of the straightening roller 4.

[0060] Example 5

[0061] like Figure 2 As shown, the present invention proposes a metal saw blade straightening device. Compared with the first embodiment, the difference in this embodiment is that the driving component includes a chain drive structure 11 and a motor 12.

[0062] The motor 12 is mounted below the worktable 1 via a bracket;

[0063] There are multiple chain drive structures 11, and each chain drive structure 11 is connected to two adjacent positioning rollers 5 and a motor 12 respectively.

[0064] In this embodiment, multiple chain drive structures 11 are respectively connected to the rotating shafts of two adjacent positioning rollers 5, so that the rotating shafts of multiple positioning rollers 5 are connected sequentially through the chain drive structures 11 to form a linkage structure, thereby ensuring the synchronicity between multiple positioning rollers 5. The positioning rollers 5 are also connected to the motor 12 through the chain drive structures 11, so that the motor 12 can drive multiple positioning rollers 5 to rotate synchronously through the chain drive structures 11, thereby realizing the conveying of the saw blade in the clamping state and avoiding the phenomenon of poor conveying or jamming caused by deformation when the saw blade is deformed.

[0065] In this invention, the connecting block 15 is installed at the end of the adjusting bolt 7 by fixing bolt 14, and the limiting plate 16 is wrapped around the outside of the connecting block 15 and connected to the straightening roller 4, so that the limiting plate 16 limits the position of the connecting block 15, thereby connecting the adjusting bolt 7 to the straightening roller 4. The adjusting bolt 7 is rotated inside the internal thread tube 13, so that the position of the adjusting bolt 7 is adjusted through the internal thread tube 13, thereby causing the straightening roller 4 to move with the position adjustment of the adjusting bolt 7, and causing the straightening roller 4 to drive the sliding rod 6 to slide on the mounting plate 2 or the fixed plate 10, so that the straightening roller 4 is stably adjusted, and the center position of the straightening roller 4 clamping the saw blade on the mounting plate 2 and the fixed plate 10 is adapted to the saw blade size. Then the linear drive 8 is connected via the fixing bolt 14. Mounting plate 2 drives pressure roller 3 to move towards positioning roller 5, so that pressure roller 3 and positioning roller 5 cooperate to clamp the saw blade. Mounting plate 2 also drives straightening roller 4 to move towards straightening roller 4 on fixed plate 10, so that straightening roller 4 limits the saw blade. At the same time, motor 12 is started, so that motor 12 drives multiple positioning rollers 5 to rotate synchronously through chain drive structure 11, and positioning roller 5 cooperates with pressure roller 3 to carry out conveying work. During the conveying process, when the saw blade passes through the area between two straightening rollers 4, straightening roller 4 applies pressure to the saw blade, causing the saw blade to deform in this area. When it is conveyed between positioning roller 5 and pressure roller 3, it achieves reset deformation. The straightening roller 4, positioning roller 5 and pressure roller 3 deform the saw blade multiple times to complete the saw blade straightening.

[0066] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
