[0025] The bending machine body 1 used in the present application is a product that can be directly purchased on the market. Its principle and connection method are existing technologies well known to those skilled in the art, so they will not be described here in detail.

[0026] An adjustable bending mechanism of an oil-electric hybrid CNC bending machine comprises: a bending machine body 1;

[0027] A fixed structure 2 is installed on the bending machine body 1, and the fixed structure 2 includes a mounting block 21, the mounting block 21 is fixedly mounted on the inner side of the bending machine body 1, a movable block 22 is slidably mounted on the inner side of the mounting block 21, a first threaded rod 23 is movably mounted on the inner side of the mounting block 21 through a bearing, a wire rope 24 is fixedly connected to the top surface of the movable block 22, a moving frame 25 is installed on the upper side of the movable block 22, a rotating block 26 is movably mounted on the upper end of the moving frame 25 through a rotating shaft, and a first threaded rod 23 is fixedly connected to the outer wall of the rotating shaft. The coil spring 28 and the end of the rotating block 26 are fixedly connected with a pressing block 27, the surface of the rotating block 26 is fixedly connected with a connecting block 29, and the top surface of the movable block 22 is provided with a magnetic block 210. The first threaded rod 23 is rotatable and can drive the movable frame 25 to move forward and backward through the magnetic block 210. When the movable frame 25 is in contact with the rear wall of the panel, the rotating block 26 can be pulled forward by the wire rope 24 to rotate, and the pressing block 27 can be pressed on the top surface of the panel, which can conveniently limit and fix the panel, thereby improving the use efficiency of the device.

[0028] Furthermore, a support structure 3 is installed on the front of the bending machine body 1, and the support structure 3 includes a bracket 31, which is fixedly connected to the front of the bending machine body 1, and the upper end of the bracket 31 is fixedly connected to a guide rod 32, and a push plate 33 is slidably installed on the guide rod 32. The upper end of the bracket 31 is threadedly connected to a second threaded rod 34, and the plate is placed on the guide rod 32 and the bending machine body 1, and then the second threaded rod 34 is rotated. The second threaded rod 34 is threadedly connected to the push plate 33, so the rotation of the second threaded rod 34 drives the push plate 33 to move on the guide rod 32, and the push plate 33 pushes the plate to send the plate into the inner side of the bending machine body 1.

[0029] Furthermore, the front end of the first threaded rod 23 is exposed from the front side of the bending machine body 1, the mounting block 21 is threadedly connected to the movable block 22, the movable block 22 and the movable frame 25 are magnetically fixed by the magnetic block 210, and the rotating mounting block 21 can drive the movable block 22 to move, and the movement of the movable block 22 can drive the movable frame 25 to move through the magnetic block 210.

[0030] Furthermore, the middle part of the wire rope 24 is passed through the inside of the movable frame 25, and the upper end of the wire rope 24 is fixedly connected to the connecting block 29. The wire rope 24 can move in the movable frame 25. When the wire rope 24 is subjected to tension, it can drive the rotating block 26 to rotate through the connecting block 29.

[0031] Furthermore, the movable frame 25 is slidably installed inside the mounting block 21, and the upper end of the movable frame 25 is exposed from the top surface of the mounting block 21. One end of the coil spring 28 is fixedly connected to the movable frame 25, and the coil spring 28 provides power for resetting the rotating block 26 on the movable frame 25.

[0032] Furthermore, the second threaded rod 34 is threadedly connected to the push plate 33 , and rotating the second threaded rod 34 can drive the push plate 33 to slide on the guide rod 32 .

[0033] Working principle: During processing, the plate is placed on the guide rod 32 and the bending machine body 1, and then the second threaded rod 34 is rotated. The second threaded rod 34 is threadedly connected with the push plate 33. Therefore, the rotation of the second threaded rod 34 drives the push plate 33 to move on the guide rod 32, and the push plate 33 pushes the plate to send the plate into the inner side of the bending machine body 1;

[0034] Then, the first threaded rod 23 is rotated, and the first threaded rod 23 is threadedly connected with the movable block 22. The rotation of the first threaded rod 23 drives the movable block 22 to move in the mounting block 21, and the mounting block 21 drives the movable frame 25 to move through the magnetic block 210, and the movable frame 25 moves forward to the plate. When the movable frame 25 is in contact with the rear wall of the plate, the rotating first threaded rod 23 cannot drive the movable frame 25 to move through the movable block 22, so the movable block 22 moves forward relative to the movable frame 25, and the magnetic block 210 is released from the magnetic attraction with the movable frame 25. When the movable block 22 moves, it pulls the wire rope 24, and the wire rope 24 pulls the connecting block 29, so that the rotating block 26 rotates forward at the upper end of the movable frame 25, and the rotating block 26 drives the pressing block 27 to rotate downward to fit the top surface of the plate to press the plate down and fix it, which is convenient and labor-saving to operate.

[0035] After the processing is completed, the first threaded rod 23 is rotated in the opposite direction to drive the movable block 22 to move backward, and the wire rope 24 is retracted into the movable frame 25. The rotating block 26 will be reset under the action of the coil spring 28, driving the pressure block 27 to release the fixation of the plate. At the same time, the movable block 22 and the movable frame 25 will be magnetically connected through the magnetic block 210. Therefore, the movement of the movable block 22 can drive the movable frame 25 to move, so that the fixed structure 2 is reset, which is convenient for removing the plate.
