[0021] There are two hydraulic rods 2 , which are equidistantly distributed on one side surface of the bending machine 1 , and the top surface of the extrusion plate 3 is fixedly connected to the top surfaces of the two hydraulic rods 2 .
[0022] Both ends of the rotating shaft 5 are fixedly connected to the inner wall of the mounting groove 4 . There are two bearings 8 , which are equidistantly distributed on the inner wall of the rotating plate 6 . The outer surfaces of the bearings 8 are fixedly connected to the inner wall of the rotating plate 6 .
[0023] The inner wall of the bearing 8 is movably and rotatably connected to the outer surface of the rotating shaft 5 , and one side surface of the rotating plate 6 is in movably contact with one side surface of the extrusion plate 3 .
[0024] When the rotation is completed, the plate is extruded and bent. When the hydraulic rod 2 drives the extrusion plate 3 to move downward again, the bending plate 9 arranged on the bottom surface of the rotating plate 6 will contact the surface of the plate, thereby punching the notch opened on the surface of the plate, thereby realizing partial bending of the plate. Embodiment 2
[0025] Based on the above Example 1, please refer to Figure 1-Figure 3The driving assembly includes a first magnet 10, a second magnet 11 is installed on one side surface of the rotating plate 6, an adjusting disk 12 is installed on one side surface of the rotating plate 6, a driving motor 13 is installed on the top surface of the extrusion plate 3, and the first magnet 10 is installed on one side surface of the extrusion plate 3.
[0026] There are two second magnets 11 , which are equidistantly distributed on one side surface of the rotating plate 6 . The second magnets 11 are in movable contact with the first magnet 10 , and the adjustment disk 12 is fixedly connected to the output of the driving motor 13 .
[0027] When the driving motor 13 drives the rotating plate 6 to rotate 180 degrees through the adjusting disk 12, one side surface of the rotating plate 6 will contact with one side surface of the extrusion plate 3. Since the second magnet 11 is installed on one side surface of the rotating plate 6, after 180 degrees of rotation, the second magnet 11 will contact with the first magnet 10 installed on one side surface of the extrusion plate 3. When the two are in contact with each other, magnetic attraction will be generated, so that the angle of the rotating plate 6 is fixed by the first magnet 10 and the second magnet 11.
[0028] The working principle and use process of the utility model are as follows: when the bending machine 1 is needed, the plate to be bent is placed on the top surface of the bending machine 1, and the plate is pushed so that the plate is located on the bottom surface of the extrusion plate 3. When the extrusion plate 3 is aligned with the bending position of the plate, the hydraulic rod 2 is started. When the hydraulic rod 2 is started, the extrusion plate 3 installed on its bottom surface is driven to move, and the extrusion plate 3 is moved to contact with the top surface of the plate and squeeze the plate, so that the squeezed plate is deformed. After the extrusion is completed, the hydraulic rod 2 is reset to drive the extrusion plate 3 to move upward, so that the stamping of the plate is completed and the bending effect of the plate is achieved. When a notch is opened on the surface of the plate and local bending is required, the driving motor 13 is started at this time. When the driving motor 13 is started, the adjusting disk 12 installed on the output end thereof is driven to rotate, and the adjusting disk 12 is fixedly connected to the rotating plate 6, so when the adjusting disk 12 rotates, the rotating plate 6 is driven to rotate. A notch is opened on one side surface of the rotating plate 6 There is an adjustment hole 7, and a bearing 8 is installed on the inner wall of the adjustment hole 7, and the inner wall of the bearing 8 is movably connected to the outer surface of the rotating shaft 5. Therefore, when the rotating plate 6 rotates, it will rotate according to the bearing 8 on the outer surface of the rotating shaft 5. When the driving motor 13 drives the rotating plate 6 to rotate 180 degrees through the adjusting disk 12, one side surface of the rotating plate 6 will contact with one side surface of the extrusion plate 3. Because the second magnet 11 is installed on one side surface of the rotating plate 6, after 180 degrees of rotation, the second magnet 11 will contact with the first magnet 10 installed on one side surface of the extrusion plate 3. When the two contact each other, magnetic attraction will be generated, so that the angle of the rotating plate 6 is fixed by the first magnet 10 and the second magnet 11. When the rotation is completed, the plate is extruded and bent. When the hydraulic rod 2 drives the extrusion plate 3 to move downward again, the bending plate 9 arranged on the bottom surface of the rotating plate 6 will contact with the surface of the plate, thereby punching the notch opened on the surface of the plate, thereby realizing partial bending of the plate.
