The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figures 1 to 3 This is the first embodiment of the present invention, which provides a bending device for processing television casings, comprising:

[0031] A processing table 100, on which a mounting bracket 101 is fixedly connected;

[0032] Two lower molds 200 are symmetrically arranged on the processing table 100, and the two lower molds 200 together support the workpiece 201;

[0033] A bending mechanism 300 is mounted on a mounting bracket 101. The bending mechanism 300 includes a hydraulic cylinder 301, a stamping component 302, and an adjusting assembly 303. The hydraulic cylinder 301 is fixedly mounted on the mounting bracket 101. The stamping component 302 is mounted on the telescopic end of the hydraulic cylinder 301. The stamping component 302 includes a first stamping block 302-1 and two sets of second stamping blocks 302-2. The adjusting assembly 303 is mounted on the first stamping block 302-1, and adjusts the relative position of the first stamping block 302-1 and the two second stamping blocks 302-2.

[0034] Two sets of drive mechanisms 400 are symmetrically arranged on the upper end of the processing table 100. The distance between the two lower molds 200 is adjusted by the two drive mechanisms 400.

[0035] The adjustment component 303 includes a fixed block 303a and a dual-axis motor 303b. The first stamping block 302-1 has a connecting cavity. The fixed block 303a is fixedly installed on the inner wall of the connecting cavity. The dual-axis motor 303b is fixedly installed on the fixed block 303a. Both output ends of the dual-axis motor 303b are fixedly connected to screws 303c. Both screws 303c are threadedly connected to threaded cylinders 303d. Two rectangular openings are symmetrically opened on the side wall of the first stamping block 302-1. One end of each of the two threaded cylinders 303d passes through the rectangular opening and is fixedly connected to the second stamping block 302-2. The synchronous lateral displacement of the two second stamping blocks 302-2 relative to the first stamping block 302-1 is achieved by driving the dual-axis motor 303b.

[0036] Furthermore, the adjustment assembly 303 also includes four sets of auxiliary structures 303e symmetrically arranged. Each set of auxiliary structures 303e includes a round rod 303e-1 and a sliding plate 303e-2. Each round rod 303e-1 is fixedly connected to the corresponding sliding plate 303e-2. Four round holes are symmetrically opened on the side wall of the second stamping block 302-2. Each round rod 303e-1 passes through the round hole and is fixedly connected to the second stamping block 302-2. Each sliding plate 303e-2 is slidably connected to the inner wall of the connecting cavity.

[0037] Each drive mechanism 400 includes a fixed plate 401, a reduction motor 402, and a connecting plate 403. Each fixed plate 401 and connecting plate 403 are fixedly connected to the processing table 100. Each reduction motor 402 is fixedly mounted on the fixed plate 401. Each reduction motor 402 has a worm gear 404 fixedly connected to its output end. The end of each worm gear 404 facing away from the reduction motor 402 is rotatably connected to the connecting plate 403. Each worm gear 404 is meshed with a worm wheel 405. A bidirectional threaded rod 406 is fixedly inserted at the center of each worm wheel 405. Both ends of each bidirectional threaded rod 406 are rotatably connected to the mounting bracket 101. Each lower mold 200 has two threaded holes symmetrically provided at its bottom, which are respectively connected to the left and right helical sections of the bidirectional threaded rod 406.

[0038] In use, the hydraulic cylinder 301 drives the stamping part 302 to press down, and the first stamping block 302-1 and the second stamping block 302-2 work together to bend the workpiece 201 in multiple stages. When the dual-axis motor 303b starts, the screw 303c drives the threaded cylinder 303d to move laterally along the rectangular opening, which drives the second stamping block 302-2 to move synchronously, thereby adjusting the stamping width to adapt to the bending requirements of different workpieces 201. The distance between the first stamping block 302-1 and the second stamping block 302-2 can be dynamically adjusted according to the actual situation through the adjustment component 303 to achieve one-time forming of complex contours.

[0039] The geared motor 402 drives the worm gear 404 to rotate, which in turn drives the worm wheel 405 and the bidirectional threaded rod 406 to rotate. When the bidirectional threaded rod 406 rotates, the two sets of lower molds 200 move synchronously in opposite directions along the guide rail of the processing table 100, quickly adjusting the spacing to adapt to workpieces 201 of different widths.

[0040] Example 2

[0041] Reference Figures 1 to 3 This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes an ejection mechanism 500 and two sets of pushing mechanisms 600. The ejection mechanism 500 is disposed on the processing table 100 and is used to eject the bent workpiece 201 from the lower mold 200. The two sets of pushing mechanisms 600 are symmetrically disposed on the mounting frame 101 and are used to push the unprocessed workpiece 201 to the center position of the device.

[0042] The ejection mechanism 500 includes a U-shaped bracket 501 and a cylinder 502. The U-shaped bracket 501 is fixedly connected to the processing table 100. Four connecting holes are symmetrically opened on the U-shaped bracket 501. Each bidirectional threaded rod 406 passes through two corresponding connecting holes. Each cylinder 502 is fixedly installed on the processing table 100. Each cylinder 502 passes through the U-shaped bracket 501 and is fixedly connected to an ejection plate 503, which is used to lift the bent workpiece 201.

[0043] Each push mechanism 600 includes a mounting base 601 and an electric telescopic rod 602. Each mounting base 601 is fixedly mounted on the mounting frame 101, and each electric telescopic rod 602 is fixedly mounted on the mounting base 601. Each telescopic end of the electric telescopic rod 602 is fixedly connected to a push plate 603, which is used to push the unprocessed workpiece 201 to the center position of the device.

[0044] Specifically, a controller 102 is fixedly installed on the mounting bracket 101. The controller 102 establishes a control connection with the hydraulic cylinder 301, the dual-axis motor 303b, the geared motor 402, the air cylinder 502, and the electric telescopic rod 602 to control the linkage operation of each actuator.

[0045] In use, the cylinder 502 vertically lifts the bent workpiece 201 through the ejector plate 503, avoiding the risk of deformation caused by manual removal of the workpiece. The telescopic end of the electric telescopic rod 602 pushes the unprocessed workpiece 201 to the center of the lower mold 200 through the push plate 603.

[0046] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
