[0002] A bending machine is a machine capable of bending thin plates. Its main structure includes a support frame, a worktable, and a clamping plate. The worktable is placed on the support frame and consists of a base and a pressure plate. The base is connected to the clamping plate via a hinge. The base comprises a housing, a coil, and a cover plate. The coil is placed in a recess within the housing, and the top of the recess is covered by the cover plate. During operation, the coil is energized by a wire, generating an attractive force on the pressure plate, thus clamping the thin plate between the pressure plate and the base. Because electromagnetic clamping is used, the pressure plate can be made to meet various workpiece requirements, and workpieces with side walls can be processed. Operation is also very simple.

Figure 1-5 The system includes a base plate 1, with a bending groove at the center of its top side. A U-shaped support frame 2 is fixedly connected to the top side of the base plate 1. A mounting hole is provided on the top side of the U-shaped support frame 2, and an electric push rod 3 is fixedly connected to the inner wall of the mounting hole. A mounting plate 4 is fixedly connected to the output shaft of the electric push rod 3. Multiple bending knives 5 are slidably mounted on the bottom side of the mounting plate 4. Magnet blocks 6 are fixedly mounted on the left side of each of the multiple bending knives 5, and magnetic grooves are provided on the right side of each of the multiple bending knives 5. These magnetic grooves are respectively connected to the multiple magnet blocks 6. Adaptation: By setting up the magnet 6 and magnetic groove, an appropriate number of bending knives 5 are selected according to the width of the bending plate, and the selected bending knives 5 are installed on the mounting plate 4. At this time, the magnet 6 and magnetic groove can make two adjacent bending knives 5 fit together tightly to prevent affecting the bending quality. Using this method, any number of bending knives 5 can be added or removed according to the usage requirements, thereby avoiding the waste of driving energy consumption, achieving the purpose of saving processing costs, and facilitating the promotion and use.
[0021] In this application, the mounting plate 4 has multiple first insertion holes 7 on both the front and rear sides, and multiple bending knives 5 have multiple second insertion holes 8 on their outer sides. Each pair of first insertion holes 7 and multiple second insertion holes 8 forms a group, and a positioning rod 9 is movably inserted into the inner wall of each group of insertion holes. A limit sleeve 10 is fixedly fitted on the outer side of each positioning rod 9. By setting the positioning rod 9 and the limit sleeve 10, the selected bending knives 5 are installed in the center on the mounting plate 4. At this time, the first insertion holes 7 and the second insertion holes 8 are on the same straight line. The positioning rod 9 passes through the first insertion hole 7 and the second insertion hole 8 and the limit sleeve 10 is installed. At this time, the installed bending knives 5 can be limited and fixed to prevent displacement during subsequent bending operations.
[0022] In this application, the top side of the U-shaped support frame 2 has two guide holes, and the inner walls of the two guide holes are slidably connected with guide rods 11. The two guide rods 11 are fixedly connected to the top side of the mounting plate 4. By setting the guide rods 11, when the mounting plate 4 moves up or down, the two guide rods 11 and the guide holes cooperate with each other to keep the mounting plate 4 moving in a vertical direction and avoid deviation.
[0023] In this application, four first support rods 12 are fixedly connected to the top side of the base plate 1, and all four first support rods 12 are fixedly connected to the U-shaped support frame 2.
