[0003] For example, Chinese Patent Publication No. CN219724352U discloses a plate supporting device for a bending machine, including a frame, a bracket hinged to the frame, and a driving mechanism for driving the bracket to flip. In the above-mentioned published document, the frame is placed in front of the workbench of the bending machine, and the plate is placed on the bracket. When the bending machine bends the plate, after the driving mechanism drives the bracket to flip, the bracket supports the plate, which not only avoids the influence of the warped plate on the bending process and deformation, but also reduces the labor intensity of the operator. The operator does not need to be distracted to hold the plate and can concentrate on operating the bending machine. However, when this patent is used, due to its overly simple structure, it is not conducive to effectively limiting and supporting the plate, thus increasing the labor intensity of the staff. Therefore, the technical personnel in this field provide a plate supporting device for a bending machine to solve the problems raised in the above background art. Summary of the Utility Model

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

[0020] Please refer to Figures 1-3 , the present invention provides a technical solution for a sheet supporting device of a bending machine: including a base 1 and a cross frame 2 fixedly installed at the central position outside the base 1. At the central position of the outer top of the cross frame 2, a first automatic push rod 3 is fixedly installed, and the telescopic end of the automatic push rod penetrates through the cross frame 2 and extends into the interior of the cross frame 2 and is fixedly installed with a pressing die seat. On the outer top of the base 1 and inside the cross frame 2, a supporting seat 5 is fixedly installed through a first bolt 4. The pressing die seat includes a cross plate 16 fixedly installed at the telescopic end of the first automatic push rod 3. At both ends of the outer side wall of the cross plate 16, second sliders are fixedly installed. Second chutes are opened on the inner side walls of both sides of the cross frame 2, and the second sliders are slidably sleeved in the inner sides of the second chutes. A pressing template 17 that fits well with the supporting seat 5 is closely attached to the outer bottom of the cross plate 16. Limiting plates 19 are fixedly installed on the outer side walls of both sides of the cross plate 16 through second bolts 18. At the same time, the corresponding inner side walls of the two limiting plates 19 are closely attached to the outer side wall of the pressing template 17 to fix the pressing template 17. First, place the sheet to be processed on the outer surface of the supporting seat 5, then tighten the first bolt 4 to drive the limiting plates 19 to approach each other, and then limit and fix the pressing template 17 corresponding to the supporting seat 5 on the cross plate 16. After that, start the first automatic push rod 3 to drive the cross plate 16 to move downward along the second chute, driving the pressing template 17 to perform bending processing on the sheet.

[0021] On the outer top of the base 1 and at the outer ends of the cross frame 2, through straight slot openings 6 are provided. At the center position of the inner bottom surface of the base 1, a second automatic push rod 7 is fixedly installed. The telescopic end of the second automatic push rod 7 is fixedly installed with a square plate 8. At both ends of the outer top of the square plate 8 and along the inner sides of the two groups of straight slot openings 6, brackets 9 are fixedly installed. Through open openings 10 are provided on the outer side walls of both sides of the two groups of brackets 9. At the upper and lower ends of the inner sides of the four groups of open openings 10, a first spring 11 and a second spring 12 are respectively fixedly installed. At the same time, a connecting block 13 is fixedly installed at the ends of the first spring 11 and the second spring 12 that are close to each other. On the corresponding outer side walls of the four groups of connecting blocks 13, a pressing shaft 14 is rotatably installed. At both ends of the outer peripheral surface of the two pressing shafts 14, limiting rings 15 are rotatably sleeved. On the inner side walls of both sides of the four groups of open openings 10, first sliding grooves are provided. At the same time, on the outer side walls of both sides of the four groups of connecting blocks 13, first sliding blocks are fixedly installed. The first sliding blocks are slidably connected to the inner sides of the first sliding grooves. When the second automatic push rod 7 is started to drive the square plate 8 to move, thereby driving the brackets 9 to move upward along the inner sides of the straight slot openings 6, then the plate is placed on the supporting seat 5, and the pressing shaft 14 presses both sides of the plate. Then, the limiting ring 15 is rotated to limit the plate. Immediately when the plate is bent, both sides of the plate will slowly tilt under the elastic action of the pressing shaft 14, the first spring 11 and the second spring 12, avoiding the need for workers to hold the plate by hand, with high labor intensity, and at the same time preventing the plate from shifting during the bending process, which affects the processing effect.

[0022] The working principle of the present utility model is as follows: When in use, first start the second automatic push rod 7 to drive the square plate 8 to move, thereby driving the brackets 9 to move upward along the inner sides of the straight slot openings 6 to the outer top of the base 1. Then, according to needs, the plate is placed on the supporting seat 5, and the pressing shaft 14 presses both ends of the plate. At the same time, the limiting ring 15 is rotated to fit and limit the outer side walls of both ends of the plate.

[0023] At the same time, start the first automatic push rod 3 to drive the cross plate 16 to move downward along the second sliding groove, driving the pressing template 17 to perform bending processing on the plate. During the bending process, both sides of the plate drive the connecting block 13 to slowly tilt under the elastic action of the pressing shaft 14, the first spring 11 and the second spring 12, thereby facilitating the processing of the plate, avoiding the need for workers to hold the plate by hand, with high labor intensity, and at the same time preventing the plate from shifting during the bending process.

[0024] Meanwhile, when different forms of bending need to be performed on the plate, only need to rotate the first bolt 4 and the second bolt 18, then the pressing template 17 and the supporting seat 5 can be disassembled, and then directly replace the corresponding pressing template 17 and the supporting seat 5.

[0025] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special instructions and limitations.
