[0002] A letter bending machine is an automated advertising device that is controlled by software and processes programs to automatically bend the outer contour of metal luminous letters into shape. Currently, in advertising production, the literal surface treatment of metal luminous letters is mainly completed by a carving machine or a plasma cutting machine. With the rapid development of the advertising production industry, the advertising equipment for literal surface treatment has entered a stage of mature development; the emergence of the letter bending machine is bound to bring a revolutionary breakthrough to the advertising production industry. Through software control, the letter bending machine can accurately fold the edges of metal letters and achieve high-precision fitting with the literal surface and the bottom plate, greatly increasing the strength and aesthetics of the luminous letters. When bending materials, a single-knife structure for a letter bending machine is required.

[0003] Currently, when bending materials, it generally requires workers to manually use a semi-automatic bending device. Although this method can effectively bend the materials, the bending process is time-consuming and laborious, thus reducing the bending efficiency of the materials and increasing the workload of the workers. Although there are also some devices that can perform full-automatic bending of materials, the structures of such devices are generally complex and bulky, which is not convenient for subsequent maintenance operations by workers, and is not convenient for workers to carry and handle the devices, reducing the overall practicality and portability of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. 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.

[0025] Please refer to Figure 1 - Figure 6 FIGS. 1-6, this embodiment provides a single-knife structure for a character bending machine, including a support plate 1, and further including:

[0026] A bending assembly, disposed above the support plate 1 and used for bending the material;

[0027] A driving assembly, disposed at the bottom of the support plate 1 and used for driving the bending assembly to start running;

[0028] The lifting component is located below the support plate 1 and is used to lift the components inside the bending component, so that the bending component can effectively bend the material.

[0029] The above working principle: When it is necessary to bend the material, just place the material inside the bending component first. At this time, the driving component starts to operate, and the driving component can effectively drive the bending component to start operating. At this time, the material can be conveniently and effectively bent through the bending component, effectively improving the bending efficiency and effect of the material. Moreover, the overall structure of this device is simple and clear and the volume is small, which is convenient for the staff to repair the device later, and at the same time, it is convenient for the staff to transport the whole device, effectively improving the overall practicality of the device. Through the setting of the lifting component, the components inside the bending component can be conveniently lifted, so that the bending component can effectively bend the material, further improving the overall practicality of the device, saving time and effort.

[0030] In order to effectively bend the material, the bending component includes a fixed bending knife 2 fixedly installed on the upper surface of the support plate 1. An installation hole for installing the tool holder 16 is penetrated through the upper surface of the support plate 1. A tool magazine 17 is rotatably connected inside the tool holder 16 through a flanged graphite bearing 18. An activity groove for the folding bending knife rod 5 to move is penetrated through the tool magazine 17. When it is necessary to bend the material, just place the material between the fixed bending knife 2 and the folding bending knife rod 5 first. At this time, the driving component starts to operate, and the driving component will drive the tool magazine 17 to rotate synchronously. The tool magazine 17 will then drive the folding bending knife rod 5 to move synchronously. At this time, the material can be slapped to the left or right through the folding bending knife rod 5, so as to achieve the purpose of bending the material.

[0031] Considering that when bending the material, it is necessary to move the folding bending knife rod 5, the driving component includes a fixed frame 6 fixedly connected to the bottom of the support plate 1. A reducer 8 is fixedly connected to the bottom of the fixed frame 6. A servo motor 7 is fixedly connected to the bottom of the reducer 8. The output end of the torque of the servo motor 7 is fixedly connected to the input end of the reducer 8. An active gear 9 is fixedly connected to the outside of the output end of the reducer 8. Tooth grooves meshing with the active gear 9 are equidistantly arranged on the outside of the tool magazine 17. When it is necessary to bend the material, just place the material between the folding bending knife rod 5 and the fixed bending knife 2 first. At this time, the servo motor 7 starts to operate, and the servo motor 7 will drive the reducer 8 to start operating synchronously. The reducer 8 will then drive the active gear 9 to rotate synchronously. Since tooth grooves meshing with the active gear 9 are equidistantly arranged on the outside of the tool magazine 17, the tool magazine 17 will rotate synchronously at this time, driving the folding bending knife rod 5 to rotate synchronously. At this time, the material can be effectively bent through the cooperation between the folding bending knife rod 5 and the fixed bending knife 2.

[0032] In order to effectively lift the folding bending rod 5, the lifting assembly includes a mounting frame 10 fixedly connected to the bottom of the support plate 1. A rotating groove for the rotation of the tool magazine 17 is formed through the upper surface of the mounting frame 10. Connecting rods 11 are symmetrically arranged at the bottom of the tool magazine 17. The bottom ends of the two connecting rods 11 are fixedly connected with a mounting disc 12. A lifting cylinder 3 is fixedly connected to the bottom of the mounting disc 12. The telescopic end of the lifting cylinder 3 is fixedly connected with a connecting block 13. The upper surface of the connecting block 13 is fixedly connected to the bottom of the folding bending rod 5. When the material needs to be bent, the lifting cylinder 3 starts to operate. At this time, the lifting cylinder 3 will drive the connecting block 13 to move synchronously, and the connecting block 13 will then drive the folding bending rod 5 to move synchronously. At this time, the folding bending rod 5 can be effectively lifted, so that the folding bending rod 5 can effectively bend the material.

[0033] In order to effectively control the up and down position of the folding bending rod 5, two magnetic switches 4 are fixedly installed outside the lifting cylinder 3. Through the setting of the magnetic switches 4, it is convenient for the staff to control the up and down position of the folding bending rod 5, so that the folding bending rod 5 can effectively bend materials of different heights, effectively improving the overall practicability of the device.

[0034] In addition, in order to limit the left or right rotation of the tool rod along with the tool magazine, photoelectric switch sensors 14 are symmetrically arranged at the bottom of the support plate 1. A bending sensor sensing piece 15 is fixedly installed on the upper surface of the driving gear 9. The bending sensor sensing piece 15 is located between the two photoelectric switch sensors 14. The bending sensor sensing piece 15 rotates synchronously with the driving gear 9. When the bending sensor sensing piece 15 moves into the photoelectric switch sensor 14, the photoelectric switch sensor 14 can sense the signal. At this time, the left or right limit processing of the tool rod can be carried out through the cooperation between the bending sensor sensing piece 15 and the photoelectric switch sensor 14.
