The bottom of the connecting shaft 18 is fixed to the surface of the top of the rotating disk 15. A plurality of connecting rods 19 are fixed to the top of the movable plate 16. The top of the connecting rod 19 is fixed to the surface of one of the movable frames 7. When the two resistance bars 9 are located at the front end position of the upper pressing platform 4, the plate body 5 is placed in the middle position of the two groups of resistance bars 9. Then, the motor 14 is started so that the two resistance bars 9 can resist the plate body 5 so that it can move to the bottom position of the upper pressing platform 4. After pressing, the motor 14 can be started again so that the two groups of resistance bars 9 can resist the plate body 5 and move to the front end position of the upper pressing platform 4, thereby avoiding the situation where the hands are easily crushed by the upper pressing platform 4 due to operational errors when manually placing the plate body 5.

[0021] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that a threaded barrel 10 is rotatably connected to one side of the surface of one end of one of the movable frames 7, and a threaded rod 11 is threadedly connected to the middle position of the threaded barrel 10. One end of the threaded rod 11 is fixed to the surface of the other opening 6. An embedded shaft 8 is inserted through the surface of the two movable frames 7 at the inner cavity positions of the openings 6 at adjacent positions. The two ends of the embedded shaft 8 are fixed to the two ends of the inner wall of the openings 6 at adjacent positions. The embedded shaft 8 can limit the movement trajectory of the two movable frames 7. By twisting the threaded barrel 10 by hand, the threaded rod 11 can move in the horizontal direction, so that the distance between the two movable frames 7 can be adjusted, so that plate bodies 5 of various lengths can be moved.

[0022] Further as Figure 4As shown, it is worth mentioning that two fixed blocks 20 are fixed at the positions on both sides of the rotating disk 15 on the bottom surface of the workbench 1, and support rods 21 are inserted through the surfaces on both sides of the interference groove 17. The two ends of the support rods 21 are fixed to the surfaces of the fixed blocks 20 at adjacent positions. The support rods 21 can limit the movable plate 16 and support the interference groove 17 at the same time, thereby improving the smoothness of the movement of the movable plate 16.

[0023] Further as Figure 2 As shown, it is worth mentioning that a limiting cylinder 12 is fixed to the other side of the surface of one end of one of the movable frames 7, and a limiting shaft 13 is inserted through the middle position of the limiting cylinder 12. One end of the limiting shaft 13 is fixed to the surface of the other opening 6. Since the limiting shaft 13 can only move horizontally along the inner cavity of the limiting cylinder 12, it can further limit the movement trajectory of the opening 6, thereby improving the connection effect between the two openings 6.

[0024] This solution has the following working process: in actual use, when the user needs to perform a punching operation on the plate body 5, the motor 14 is started to rotate the movable plate 16, so that the connecting shaft 18 can make a circular motion so that the connecting shaft 18 can make a reciprocating motion in the horizontal direction under the interference with the interference groove 17 and the supporting and limiting effect of the support rod 21 on the movable plate 16. When the movable frame 7 makes a reciprocating motion, it can drive the interference bar 9 to move so that it can move to one end position of the upper pressing table 4, and then the plate body 5 is placed in the middle position of the two interference bars 9 so that its two ends conflict with the adjacent interference bars 9, and the motor 14 is started again to rotate the rotating disk 15, so that the interference bar 9 conflicts with the plate body 5 It moves to the bottom position of the upper pressing platform 4, thereby controlling the hydraulic cylinder 3 so that the upper pressing platform 4 can move vertically downward to perform the punching operation on the plate body 5, and then starting the motor 14 again so that the two contact bars 9 can contact the plate body 5 and move to one end position of the upper pressing platform 4, and the punched plate body 5 is taken out and the unpunched plate body 5 is placed and the above operation is repeated, so that the punching operation on the plate body 5 can be completed in batches. When it is necessary to batch process plate bodies 5 of another type of length size, the threaded barrel 10 is twisted by hand and the opening 6 limits the movement trajectory of the movable frame 7, so that the threaded rod 11 can move in the horizontal direction under the cooperation of the threaded structure, so that the distance between the two movable frames 7 can be adjusted, so that plate bodies 5 of various length sizes can be moved.

[0025] According to the above working process, it can be known that: when the two interference bars 9 are located at the front end position of the upper pressing platform 4, the plate body 5 is placed in the middle position of the two groups of interference bars 9, and then the motor 14 is started so that the two interference bars 9 can interfere with the plate body 5 so that it can move to the bottom position of the upper pressing platform 4. After pressing, the motor 14 can be started again to allow the two groups of interference bars 9 to interfere with the plate body 5 and move to the front end position of the upper pressing platform 4, thereby avoiding the situation where the hands are easily crushed by the upper pressing platform 4 due to operational errors when manually placing the plate body 5, thereby improving the safety of use of the device, and by rotating the threaded barrel 10, the threaded rod 11 can be extended in the horizontal direction, so that the distance between the two movable frames 7 can be adjusted, so that plate bodies 5 of various lengths can be moved, thereby improving the scope of application of the device and thus improving the practicality of the device.

[0026] Further as Figure 4 As shown, it is worth mentioning that the two sides of the inner cavity of the interference groove 17 are arranged in an arc shape, and the outer peripheral surface of the connecting shaft 18 is in contact with the inner cavity surface of the interference groove 17. Due to the shape of the inner cavity of the interference groove 17, the connecting shaft 18 can be prevented from getting stuck during the circular motion.

[0027] In summary: when the two interference bars 9 are at the front end position of the upper pressing platform 4, the plate body 5 is placed in the middle position of the two groups of interference bars 9, and then the motor 14 is started so that the two interference bars 9 can interfere with the plate body 5 so that it can move to the bottom position of the upper pressing platform 4. After pressing, the motor 14 can be started again to allow the two groups of interference bars 9 to interfere with the plate body 5 and move to the front end position of the upper pressing platform 4, thereby avoiding the situation where the hands are easily crushed by the upper pressing platform 4 due to operational errors when manually placing the plate body 5, thereby improving the safety of use of the device, and by rotating the threaded cylinder 10, the threaded rod 11 can be extended in the horizontal direction, so that the distance between the two movable frames 7 can be adjusted, so that plate bodies 5 of various lengths can be moved, thereby improving the scope of application of the device, thereby improving the practicality of the device, and due to the inner cavity shape setting of the interference groove 17, the connecting shaft 18 can be prevented from getting stuck during the circular motion.

[0028] The hydraulic cylinder 3 and the motor 14 can be purchased on the market. The hydraulic cylinder 3 and the motor 14 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.
