Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1 - Figure 5 As shown, this embodiment provides a three-knife structure for a letter bending machine, including a mounting frame 1, and further including:

[0027] An upper support 2 and a lower support 3, which are respectively fixedly installed on the upper surface and the lower surface of the mounting frame 1;

[0028] A connecting plate 4, which is arranged in front of the mounting frame 1;

[0029] A bending assembly, which is arranged inside the mounting frame 1 and is used for bending the material;

[0030] A fixing assembly, which is arranged inside the connecting plate 4 and is used for fixedly clamping the material;

[0031] A lifting assembly, which is located below the mounting frame 1 and is used for adjusting the height position of the internal components of the bending assembly.

[0032] The above working principle: When it is necessary to bend the material, just insert the material into the gap between the connecting plate 4 and the mounting frame 1 first, and then use the fixing assembly to fixedly clamp the material. When the material is fixed, the bending assembly starts to operate. At this time, the material can be effectively bent by the bending assembly. Moreover, three tool bars are used when the device bends the material, and the staff can replace and use different tool bars according to actual needs, effectively improving the bending effect and efficiency of the material, and improving the overall practicability of the device. Through the setting of the lifting assembly, the height position of the internal components of the bending assembly can be effectively adjusted, so that the bending assembly can effectively bend materials of different heights, further improving the overall practicability of the device. Moreover, the structure of this device is simple and clear, which is convenient for the subsequent maintenance of the staff, saving time and effort.

[0033] In order to effectively bend the material, the bending assembly includes a fixed bending knife 16 fixedly installed on the upper surface of the mounting frame 1. A guiding groove for the material to move is provided inside the fixed bending knife 16. Mounting holes for installing flanged graphite bearings 18 are penetrated through the upper and lower surfaces of the mounting frame 1. The upper tool magazine 12 and the lower tool magazine 17 are respectively rotatably connected to the interiors of the two flanged graphite bearings 18. Rotating grooves for the upper tool magazine 12 and the lower tool magazine 17 to rotate are respectively provided inside the upper support 2 and the lower support 3. A driving shaft 10 is rotatably connected inside the mounting frame 1. Driving gears 11 are symmetrically provided on the outer part of the driving shaft 10. Tooth grooves meshing with the driving gears 11 are equidistantly provided on the outer parts of the upper tool magazine 12 and the lower tool magazine 17. Guiding grooves for the first tool bar 13, the second tool bar 14, and the third tool bar 15 to move are provided inside the upper tool magazine 12 and the lower tool magazine 17. When it is necessary to bend the material, first insert the material into the gap between the connecting plate 4 and the mounting frame 1, then insert one end of the material into the guiding groove inside the fixed bending knife 16, and then fix the material through the fixing component. After the material is fixed, the staff determines whether to use the first tool bar 13, the second tool bar 14, or the third tool bar 15 according to the processing pattern through the software. After the software determines, the lifting component starts to operate. At this time, the lifting component drives the first tool bar 13, the second tool bar 14, or the third tool bar 15 to perform a synchronous lifting process. After the first tool bar 13, the second tool bar 14, or the third tool bar 15 is lifted, the power mechanism drives the driving shaft 10 to rotate, the driving shaft 10 drives the driving gears 11 to rotate synchronously, the driving gears 11 drive the upper tool magazine 12 and the lower tool magazine 17 to rotate synchronously, and the upper tool magazine 12 and the lower tool magazine 17 drive the first tool bar 13, the second tool bar 14, or the third tool bar 15 to rotate synchronously. At this time, the material can be effectively bent through the cooperation between the first tool bar 13, the second tool bar 14, or the third tool bar 15 and the fixed bending knife 16 (only one tool bar works each time), thereby effectively improving the bending effect and efficiency of the material and effectively enhancing the overall practicality of the device.

[0034] Considering that it is necessary to fix the material first when bending the material, the fixing component includes a strong magnet 5 provided inside the connecting plate 4. A handle 6 is fixedly connected to the front surface of the strong magnet 5. An activity groove for the strong magnet 5 to move is provided inside the connecting plate 4. When it is necessary to fix the material, first insert the material into the gap between the connecting plate 4 and the mounting frame 1, and then fix the material between the material and the mounting frame 1 through the strong magnet 5. At this time, the material can be effectively fixed, thus facilitating the bending process of the material.

[0035] In order to effectively lift the first tool bar 13, the second tool bar 14 or the third tool bar 15, the lifting assembly includes a chassis 7 located below the mounting frame 1. A plurality of connecting rods 8 are fixedly connected to the upper surface of the chassis 7. The tops of the plurality of connecting rods 8 are fixedly connected to the bottom of the lower tool magazine 17. A plurality of lifting cylinders 9 are fixedly connected to the bottom of the chassis 7. The telescopic ends of the plurality of lifting cylinders 9 are respectively fixedly connected to the bottoms of the first tool bar 13, the second tool bar 14 and the third tool bar 15. When the first tool bar 13, the second tool bar 14 or the third tool bar 15 needs to be used, the lifting cylinders 9 start to operate. At this time, the lifting cylinders 9 will drive the first tool bar 13, the second tool bar 14 or the third tool bar 15 to move synchronously. After the first tool bar 13, the second tool bar 14 or the third tool bar 15 is lifted, it is convenient for the staff to use the first tool bar 13, the second tool bar 14 or the third tool bar 15.

[0036] In order to effectively control the up and down positions of the first tool bar 13, the second tool bar 14 and the third tool bar 15, magnetic switches 19 are fixedly installed outside the plurality of lifting cylinders 9. Through the setting of the magnetic switches 19, it is convenient for the staff to control the up and down positions of the first tool bar 13, the second tool bar 14 and the third tool bar 15, and further improves the overall practicality of the device.

[0037] In addition, in order to prevent the third tool bar 15 from damaging the material, a plurality of bending sleeves 20 are sleeved outside the third tool bar 15. Through the setting of the bending sleeves 20, the bending sleeves 20 can be used to contact the material, thereby avoiding scratches on the outside of the material caused by the third tool bar 15 and effectively protecting the material.
