[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment proposes a bending device for processing television bezels, including a bending table 1. Two card holders 2 are symmetrically and fixedly connected to the upper surface of the bending table 1. Each card holder 2 has a placement groove 3, and each placement groove 3 contains a clamping plate 4. A first telescopic cylinder 5 is fixedly connected to each card holder 2. The driving end of the first telescopic cylinder 5 penetrates the side wall of the card holder 2 and is fixedly connected to the clamping plate 4. A centering structure 6 is provided on the outer side of each card holder 2. Two fixing plates 7 are symmetrically and fixedly connected to the center of the upper surface of the bending table 1, and a rotating shaft is rotatably connected between the two fixing plates 7. 8. The bending table 1 is provided with a flipping structure 9 for driving the rotating shaft 8 to rotate. A mounting frame 10 is fixedly connected to the rotating shaft 8. Two second telescopic cylinders 11 are symmetrically and fixedly connected to the mounting frame 10. The driving ends of the two second telescopic cylinders 11 pass through the side wall of the mounting frame 10 and are fixedly connected to the bending head 12. The TV frame is conveniently placed through the placement slot 3. The frame can be clamped and fixed by driving the clamping plate 4 through the first telescopic cylinder 5 to ensure stability during bending. The bending head 12 can be bent by driving the second telescopic cylinder 11 to move.

[0031] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the centering structure 6 further includes two symmetrical connecting frames 601 fixed to the lower end face of the bending table 1. A bidirectional screw 602 is rotatably connected between the two connecting frames 601. A motor 603 is fixedly connected to one end of each connecting frame 601. The drive end of the motor 603 is fixedly connected to the shaft end of the bidirectional screw 602. Two movable openings 604 that cooperate with the bidirectional screw 602 are opened at both ends of the upper end face of the bending table 1. A centering plate 605 is slidably connected within the movable opening 604. The bottom ends of the centering plates 605 are threadedly connected to the bidirectional screw 602. By driving the rotation of the bidirectional screw 602 through the motor 603, the two centering plates 605 can move inward or outward simultaneously, thereby facilitating the centering adjustment of the TV frame and ensuring that the bending lengths at both ends of the frame are the same.

[0032] like Figure 1 and Figure 3As shown, in a preferred embodiment, based on the above method, the flipping structure 9 further includes a gear 901 fixed to the rear end of the rotating shaft 8. A guide rail 902 is provided on the lower side of the gear 901. The bottom surface of the guide rail 902 is fixedly connected to the upper end surface of the bending table 1. A slide bar 903 is slidably connected inside the guide rail 902. A rack 904 that meshes with the gear 901 is fixedly connected to the upper end surface of the slide bar 903. A connecting piece 905 is fixedly connected to one end of the rack 904. One side of the connecting piece 905 is provided with... The third telescopic cylinder 906 is fixedly connected to the bending table 1, and the driving end of the third telescopic cylinder 906 is fixedly connected to the connecting piece 905. The driving end of the third telescopic cylinder 906 pushes the connecting piece 905 and the rack 904 to slide along the guide rail 902. The rack 904 meshes with the gear 901. Therefore, the movement of the rack 904 will drive the gear 901 and the rotating shaft 8 to rotate, thereby driving the mounting frame 10 and the bending head 12 to rotate 180 degrees, so as to facilitate the bending process of the next TV frame.

[0033] like Figure 1 As shown, in a preferred embodiment, based on the above method, the upper end face of the bending table 1 is symmetrical and fixedly connected with two limiting frames 13; the position of the mounting frame 10 can be limited, thereby facilitating the rotation of the mounting frame 10 and facilitating continuous bending processing of the frame.

[0034] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a controller 14 is further fixedly connected to the upper end face of the bending table 1. The controller 14 is electrically connected to the first telescopic cylinder 5, the second telescopic cylinder 11, the motor 603 and the third telescopic cylinder 906 respectively; thus, precise control of the first telescopic cylinder 5, the second telescopic cylinder 11, the motor 603 and the third telescopic cylinder 906 is realized, which not only improves work efficiency, but also ensures the coordinated operation between the various components.

[0035] like Figure 1 and Figure 6 As shown, in a preferred embodiment, based on the above method, a frame 15 is fixedly connected to the lower end face of the bending table 1, and support feet 16 are fixedly connected to the four corners of the lower end face of the frame 15; to facilitate the support of the bending table 1.

[0036] Specifically, when using this bending device for processing television frames: a television frame is placed in the placement slot 3 of the left-side bracket 2. The rotation of the bidirectional screw 602 driven by the motor 603 causes the two centering plates 605 to move inward simultaneously, aligning the frame. Then, the first telescopic cylinder 5 is driven to clamp the frame with the clamping plate 4. The motor 603 is then driven to rotate in the opposite direction to reset the two centering plates 605. Finally, the second telescopic cylinder 11 drives the bending head 12 to move, enabling the bending process of the frame. During processing... The next frame is placed in the placement slot 3 of the right-side card holder 2 and centered and clamped. After the left-side frame is bent, the drive end of the third telescopic cylinder 906 pushes the connecting piece 905 and the rack 904 to slide along the guide rail 902. The rack 904 meshes with the gear 901. Therefore, the movement of the rack 904 will drive the gear 901 and the rotating shaft 8 to rotate, thereby causing the mounting frame 10 and the bending head 12 to rotate 180 degrees, which facilitates the bending of the next TV frame. The frame is continuously bent, improving the bending efficiency.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
