Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to an automatic material turning device for a CNC bidirectional bending machine. Background Technology

[0002] During the manufacturing process, the tube needs to be deformed to the corresponding size and shape by a bending machine. However, the upper and lower dies of the existing bending machine are in fixed positions, so only one-way bending of the workpiece is possible. When it is necessary to bend the workpiece multiple times in both directions, the workpiece must be frequently taken out of the bending machine and turned over to achieve bending of the workpiece in both directions.

[0003] However, when dealing with heavy, large workpieces that require multiple bending in both directions, frequent handling and flipping consume a lot of time and energy, greatly reducing work efficiency, increasing labor intensity, and potentially causing danger. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic material turning device for a CNC bidirectional bending machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic material turning device for a CNC bidirectional bending machine, comprising an operating table, a fixed vertical plate fixedly connected to the upper surface of the operating table, a rotating connecting shaft passing through and fixedly connected to the side wall of the fixed vertical plate, a first power component for driving the rotating connecting shaft to rotate mounted on the fixed vertical plate, a lower clamping block fixedly connected to one end of the rotating connecting shaft, two mounting grooves opened on the side wall of the lower clamping block, threaded blocks slidably connected inside the mounting grooves, an upper clamping block fixedly connected to the two threaded blocks, a second power component for driving the threaded blocks to rise and fall mounted on the top of the lower clamping block, a mounting frame provided on the upper surface of the operating table, a lower pressing bending component mounted on the top of the mounting frame, a first cylinder fixedly connected to the upper surface of the operating table, and the piston end of the first cylinder fixedly connected to the mounting frame.

[0006] As a further description of the above technical solution:

[0007] The first power assembly includes a second servo motor fixedly connected to the side wall of the fixed upright plate. The output shaft of the second servo motor is fixedly connected to a first pulley, and the end of the rotary connecting shaft is fixedly connected to a second pulley. The first pulley and the second pulley are connected by belt drive.

[0008] As a further description of the above technical solution:

[0009] The second power assembly includes a first servo motor fixedly connected to the top of the lower clamping block. The output shaft of the first servo motor extends into the interior of the mounting slot and is fixedly connected to a threaded rod. The threaded block is threadedly connected to the outer surface of the threaded rod.

[0010] As a further description of the above technical solution:

[0011] The downward bending assembly includes a second cylinder fixedly connected to the top of the mounting frame, the output shaft of the second cylinder being fixedly connected to a fixed frame, and a downward roller being installed on the inner wall of the fixed frame.

[0012] As a further description of the above technical solution:

[0013] A first guide roller is fixedly connected to one side of the lower clamping block, and a second guide roller is fixedly connected to one side of the upper clamping block. Clamping grooves are provided on the opposite sides of the lower clamping block and the upper clamping block.

[0014] As a further description of the above technical solution:

[0015] A mounting plate is fixedly connected to the side wall of the mounting bracket, and two third cylinders are fixedly connected to the upper surface of the mounting plate. A base plate is fixedly connected to the piston end of the third cylinder.

[0016] This utility model has the following beneficial effects:

[0017] 1. Compared with existing technologies, the automatic material turning device of this CNC bidirectional bending machine starts the second cylinder. The output shaft of the second cylinder lowers the lower pressure roller through the fixed frame. The lower pressure roller cooperates with the first guide roller to bend the tube once. Then, the second servo motor is started. The output shaft of the second servo motor rotates the rotating connecting shaft, so that the lower clamping block and the upper clamping block exchange positions. The lower pressure roller cooperates with the second guide roller to bend the tube a second time. There is no need for manual tube turning, which reduces labor intensity, improves work efficiency, and ensures work safety.

[0018] 2. Compared with the existing technology, the automatic material turning device of this CNC bidirectional bending machine starts the third cylinder. The piston end of the third cylinder carries the bottom plate up, so that the bottom plate contacts the surface of the lower clamping block or the upper clamping block, ensuring the stability during bending.

[0025] Reference Figures 1 to 3 The present invention provides an automatic material turning device for a CNC bidirectional bending machine: including an operating table 1, a fixed upright plate 2 fixedly connected to the upper surface of the operating table 1, a rotating connecting shaft 3 passing through and fixedly connected to the side wall of the fixed upright plate 2, a first power component for driving the rotating connecting shaft 3 to rotate installed on the fixed upright plate 2, the first power component including a second servo motor 21 fixedly connected to the side wall of the fixed upright plate 2, a first pulley fixedly connected to the output shaft of the second servo motor 21, a second pulley fixedly connected to the end of the rotating connecting shaft 3, the first pulley and the second pulley being connected by belt drive, so that the rotating connecting shaft 3 can rotate with the lower clamping block 4;

Threaded blocks 6 are slidably connected inside the mounting grooves 5. The two threaded blocks 6 are fixedly connected to the upper clamping block 9. A second power assembly for driving the threaded blocks 6 to rise and fall is installed on the top of the lower clamping block 4. The second power assembly includes a first servo motor 7 fixedly connected to the top of the lower clamping block 4. The output shaft of the first servo motor 7 extends into the interior of the mounting groove 5 and is fixedly connected to a threaded rod 8. The threaded block 6 is threadedly connected to the outer surface of the threaded rod 8. A first guide roller 11 is fixedly connected to one side of the lower clamping block 4, and a second guide roller 12 is fixedly connected to one side of the upper clamping block 9. A clamping groove 10 is opened on the side of the lower clamping block 4 opposite to the upper clamping block 9 for placing clamping pipes.

[0027] The upper surface of the operating table 1 is provided with a mounting frame 13. A mounting plate 18 is fixedly connected to the side wall of the mounting frame 13. Two third cylinders 19 are fixedly connected to the upper surface of the mounting plate 18. A bottom plate 20 is fixedly connected to the piston end of the third cylinder 19. A downward bending assembly is installed on the top of the mounting frame 13. The downward bending assembly includes a second cylinder 15 fixedly connected to the top of the mounting frame 13.

The first cylinder 14 can move the mounting frame 13, thereby moving the downward bending assembly.

[0028] Working principle:

[0029] When in use, place the pipe between the lower clamping block 4 and the upper clamping block 9, start the first servo motor 7, and the output shaft of the first servo motor 7 rotates the threaded rod 8, causing the threaded block 6 to move the upper clamping block 9 to the lower clamping block 4, thereby clamping the pipe between the lower clamping block 4 and the upper clamping block 9.

[0030] Then the third cylinder 19 is started. The piston end of the third cylinder 19 carries the bottom plate 20 up, so that the bottom plate 20 contacts the surface of the lower clamping block 4. Then the second cylinder 15 is started. The output shaft of the second cylinder 15 carries the lower pressure roller 17 down through the fixed frame 16.

[0031] Then, the third cylinder 19 resets with the base plate 20, and the first cylinder 14 is activated. The piston end of the first cylinder 14 moves the mounting bracket 13, causing the base plate 20 to move away from the lower clamping block 4. Then, the second servo motor 21 is activated, and the output shaft of the second servo motor 21 rotates the rotating connecting shaft 3, causing the lower clamping block 4 and the upper clamping block 9 to exchange positions. Then, the first cylinder 14 resets with the mounting bracket 13, and the third cylinder 19 is activated again. The piston end of the third cylinder 19 rises with the base plate 20, causing the base plate 20 to contact the surface of the upper clamping block 9. Finally, the pipe is bent a second time by the cooperation of the lower pressure roller 17 and the second guide roller 12.
