[0027] According to the specific shape of the bending, adjust the relative position of the first mould 4 and the second mould 5, the operator needs to rotate the handle 802. The rotation of the handle 802 is transmitted through the threaded rod 803, and the rotation of the threaded rod 803 drives the connecting rod 804 to move up and down. The movement of the connecting rod 804 further drives the second mould 5 to move up and down, thereby accurately adjusting the distance between the first mould 4 and the second mould 5 to match the specific shape required for bending the metal plate. When the threaded rod 803 rotates, it is supported by the fixed block one 801 and the fixed plate 805, ensuring the stability of the threaded rod 803 during rotation. The movement of the connecting rod 804 is limited by the sliding slot 806 to prevent it from deviating from the predetermined track.

[0028] In this embodiment, the outer side wall of the two side supporting rods 2 is fixedly connected with an outer shell 14, the top of each outer shell 14 is slidingly connected with a sliding rod 11, the top of the sliding rod 11 is fixedly connected with a circular plate 10, the circular plate 10 and the outer shell 14 are fixedly connected with a spring 12, the bottom end of the sliding rod 11 is fixedly connected with a pressing plate 13, the sliding rod 11 penetrates through the outer shell 14 and extends to the top of the pressing plate 13, the pressing plate 13 is slidingly connected in the outer shell 14, the top of the top plate 3 is fixedly connected with a hydraulic cylinder 6, the output end of the hydraulic cylinder 6 is fixedly connected with a connecting plate 7, the top of the connecting plate 7 is fixedly connected with a pair of limiting rods 9, the limiting rods 9 are slidingly connected in the top plate 3, and the connecting plate 7 is fixedly connected to the top of the first die 4 on one side, and the other first die 4 is fixedly connected to the top of the workbench 1.

[0029] When the circular plate 10 on both sides is pulled up, the action of the circular plate 10 will drive the pressing plate 13 inside the outer shell 14 to move up. In this process, the spring 12 will be in a state of tension, and at this time the metal plate is placed between the two sides of the outer shell 14. Then, the operator releases the circular plate 10, and the spring-back force of the spring 12 will make the sliding rod 11 on the circular plate 10 pull down, thereby pushing the pressing plate 13 to move down and clamping the metal plate stably at the predetermined position. This action effectively prevents the metal plate from sliding during subsequent bending operations, thereby ensuring that the shape and quality of the metal plate after bending meet the expected standards. Starting the hydraulic cylinder 6 will drive the first die 4 and the second die 5 on the connecting plate 7 to move downward. The upper die cooperates with the first die 4 and the second die 5 to complete the shaping of the metal plate through precise bending operation. During the movement of the connecting plate 7, through cooperation with the limiting rods 9, the accuracy and stability of the operation are ensured.
