[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a CNC sheet metal bending machine, such as... Figures 1-5 As shown, the CNC sheet metal bending machine includes a CNC sheet metal bending machine body 1. A bending assembly 2 is provided on the front side of the CNC sheet metal bending machine body 1. Two sets of brackets 3 are fixedly installed at the front end of the CNC sheet metal bending machine body 1. Fixed sleeves 5 are fixedly installed on both sets of brackets 3. A base plate 6 is fixedly installed on the upper side of the multiple sets of fixed sleeves 5. A rocker plate 7 is rotatably installed on the base plate 6. A rotating shaft 8 is rotatably installed inside the rocker plate 7. Two sets of gears 9 are fixedly installed on the rotating shaft 8. Two sets of limiting rods 10 are movably inserted inside the rocker plate 7. The lower sides of the two sets of limiting rods 10 mesh with the two sets of gears 9.

[0025] During use, the rotating shaft 8 drives two sets of gears 9 to rotate, which in turn drives two sets of limiting rods 10 to move back and forth on the left and right ends of the rocker plate 7 under the drive of the gears 9, thereby feeding the sheet into the bending assembly 2 and feeding the sheet. When the sheet is bent and raised by the bending assembly 2, the rocker plate 7 is raised on the base plate 6 by the two sets of limiting rods 10.

[0026] Both sets of brackets 3 have uprights 4 fixedly installed at their front ends, and the connection points between the two sets of uprights 4 and the two sets of brackets 3 are set at right angles.

[0027] The two sets of uprights 4 and the two pairs of rocker panels 7 are used to shield the workers when they rotate and tilt on the base plate 6.

[0028] The front ends of the two sets of limiting rods 10 are hook-shaped, and the upper rear end of the limiting rods 10 is flush with the upper side of the rocker 7.

[0029] With the front ends of the two sets of limit rods 10 set in a hook shape, the sheet metal can be effectively limited when it is bent and warped, preventing the sheet metal from suddenly springing up and causing injury to the operator, thus further improving the safety of operation.

[0030] The bottom plate 6 is provided with a groove 11 at both ends, and a guide rod 12 is fixedly installed in each groove 11.

[0031] In use, the two groups of springs 14 reset the two groups of sliding blocks 13, and then the two groups of sliding blocks 13 drive the warped plate 7 to reset through the two groups of connecting rods 15, thereby achieving automatic resetting of the plate on the warped plate 7, improving work efficiency.

[0032] The upper side of the warped plate 7 and the front end of the two groups of limiting rods 10 are glued with protective pads, which are made of rubber.

[0033] The protective pads can effectively protect the plate during bending, prevent scratches or damage on the surface of the plate, and further improve the practicality of the bending machine.

[0034] The left and right side surfaces of the two groups of limiting rods 10 are concave, and the two groups of limiting rods 10 are slidingly arranged in front of and behind the left and right ends of the warped plate 7.

[0035] The concave design of the left and right side surfaces of the limiting rod 10 can increase the sliding limiting effect between the limiting rod 10 and the warped plate 7, making the limiting rod 10 slide more stably on the warped plate 7, and further improving the stability and safety of the bending machine.

[0036] Working principle: in use, first place the plate to be bent on the upper side of the warped plate 7, and the shaft 8 drives the two groups of gears 9 to rotate. Since the lower side of the two groups of limiting rods 10 is engaged with the two groups of gears 9, the two groups of limiting rods 10 will move forward and backward on the left and right ends of the warped plate 7 under the drive of the gears 9, thereby achieving feeding the plate into the bending assembly 2. When the plate is fed into the bending assembly 2, the bending assembly 2 starts to bend the plate. During the bending process of the plate, since the front ends of the two groups of limiting rods 10 are hook-shaped, the front end of the plate can be hooked, and then the warped plate 7 is rotated on the bottom plate 6 by the two groups of limiting rods 10 when the plate is bent and raised, and the warped plate 7 drives the two groups of sliding blocks 13 and the two groups of connecting rods 15 to slide. After the plate is bent, the two groups of sliding blocks 13 are reset by the restoring force of the two groups of springs 14, and then the two groups of sliding blocks 13 drive the warped plate 7 to reset through the two groups of connecting rods 15, thereby achieving automatic resetting of the plate on the warped plate 7, improving work efficiency. In addition, the two groups of vertical rods 4 can shield the warped plate 7 when it is rotated and raised on the bottom plate 6, which can further protect the workers and improve the safety of the operation.

[0037] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
