[0002] The steel plate bending machine is a device used to bend metal plates. The steel plate bending machine is a very important equipment in metal processing. It can bend metal plates to meet the needs of different shapes of steel plates. This machine usually includes parts such as a bracket, a workbench and a clamping plate. The steel plate bending machine can process metal plates of different shapes and sizes by replacing different molds.

[0003] When bending steel plates, traditional steel plate bending machines mostly use a top-down pushing method to extrude and bend the steel plates. Before bending, the bending position is determined by manually measuring the dimensions, and then the steel plates are manually pushed to move. During the bending process of the steel plates by the bending machines, the steel plates will be deformed, and the rear ends will be lifted up during the bending process. There is a risk of the lifted steel plates hitting the workers, causing injuries to the workers. In order to solve this technical problem, the utility model proposes a steel plate bending machine.

[0024] The interior of the mounting seat 3 is detachably connected to a pressure plate 5, and the inner wall of the mounting seat 3 is slidably connected to a clamping plate 11, one side of the clamping plate 11 is in contact with the outer surface of the pressure plate 5, and the inner side of the mounting seat 3 is threadedly connected to a fastening bolt 12, and one end of the fastening bolt 12 is located inside the mounting seat 3 and is rotatably connected to the other side of the clamping plate 11 at a fixed point, and the fastening bolt 12 generates a thrust when rotating, and the thrust generated by the fastening bolt 12 provides power for the clamping plate 11 to move its position, and the movement is limited by the extrusion force generated by the clamping plate 11 on the pressure plate 5, and the clamping plate 11 is separated from the contact with the pressure plate 5 after the fastening bolt 12 is rotated in the reverse direction. The fixed restriction on the pressure plate 5 by the contact can realize the replacement of different types of pressure plates 5.

[0025] A push plate 7 is hinged on the inner wall of the workbench 1, and a second hydraulic cylinder 8 is arranged below the push plate 7. The inner wall of the workbench 1 is connected to a base 9, and the inner wall of the base 9 is connected to the fixed end of the second hydraulic cylinder 8 for fixed-point rotation. The lower surface of the push plate 7 is connected to a base 2 10, and the output end of the second hydraulic cylinder 8 is connected to the inner wall of the base 2 10 for fixed-point rotation. The base 1 9 provides support for the second hydraulic cylinder 8, and the push plate 7 receives the thrust generated by the second hydraulic cylinder 8 through the base 2 10. When the second hydraulic cylinder 8 pushes the push plate 7 to flip, the steel plate is bent.

[0026] A conveying mechanism 6 is provided below the workbench 1, and the conveying mechanism 6 facilitates the movement of the steel plate. The conveying mechanism 6 wraps around the support frame 601, and the upper surface of the support frame 601 is connected to the lower surface of the workbench 1. The inner bottom wall of the support frame 601 is connected to two sliding sleeves 602, and the two sliding sleeves 602 are symmetrically arranged. The inner wall of the sliding sleeve 602 is slidably connected with a sliding rod 603, and one end of the sliding rod 603 located inside the sliding sleeve 602 is connected with a positioning block 604, and the outer surface of the positioning block 604 is slidably connected to the inner wall of the sliding sleeve 602. The positioning block 604 and the sliding rod 603 are supported by the sliding sleeve 602, so that the positioning block 604 and the sliding rod 603 have a sliding function. When sliding, the positioning block 604 can prevent the sliding rod 603 from detaching from the sliding sleeve 602, thereby improving the stability of the sliding rod 603 when sliding. The inner bottom wall of the sliding sleeve 602 is connected to a spring 605, and the other end of the spring 605 is connected to the lower surface of the positioning block 604 Then, the positioning block 604 is elastically supported by the spring 605, and the positioning block 604 supports the sliding rod 603.

After the steel plate is subjected to pressure outside, the conveying roller 607 pushes the sliding rod 603 to slide inside the sliding sleeve 602, and at the same time, the spring 605 is pushed to contract through the positioning block 604.

[0027] It should be noted that in actual use, the device first places the steel plate on the conveyor roller 607, and then pushes the steel plate to move in the direction of the push plate 7. While pushing the steel plate to move, the conveyor roller 607 is driven to rotate. After the steel plate moves to the bending position, the first hydraulic cylinder 4 is started to push the mounting seat 3 downward to move, and at the same time drives the pressure plate 5 to move downward. Then the pressure plate 5 contacts the steel plate and applies pressure. Then the steel plate moves downward and contacts the workbench 1. While the steel plate moves downward, the conveyor roller 607 is pushed downward. The conveyor roller 607 pushes the shaft sleeve 606 to move downward. At the same time, the shaft sleeve 606 pushes the slide bar 603 and the positioning block 604 to squeeze the spring 605. Then the second hydraulic cylinder 8 is started to push the push plate 7 to flip and bend the steel plate.
