[0023] like Figures 1-5 As shown, it illustrates a pure electric servo bending machine according to an embodiment of the present invention, including a mounting plate 1, a support plate 2, an adjusting column 3, a placement box 4, a buffer rod 5, a buffer spring 6, a first moving block 7, a second moving block 8, a first connecting frame 9, a flipping rod 10, a second connecting frame 11, a hinge 12, and a flipping plate 13. like Figure 3 and Figure 4 As shown, the support plate 2 is installed on the upper surface of the mounting plate 1. An adjusting column 3 runs through the support plate 2. A placement box 4 is installed at the top of the adjusting column 3. A buffer rod 5 is installed inside the placement box 4. A buffer spring 6 is sleeved on the outer surface of the buffer rod 5. The buffer spring 6 is installed inside the placement box 4. The first moving block 7 is slidably connected to the outer surface of the buffer rod 5. The rear end of the buffer spring 6 is installed on the front of the first moving block 7. There is a small gap between the lower surface of the first moving block 7 and the bottom inner wall of the placement box 4, so that the first moving block 7 will not flip or rub against the placement box 4 during the back and forth movement. A second moving block 8 is installed on the outer side of the first moving block 7. A first connecting frame 9 is installed on the upper surface of the second moving block 8. A flipping rod 10 is rotatably connected inside the first connecting frame 9. A second connecting frame 11 is rotatably connected inside the flipping rod 10. The flipping plate 13 is hinged to the upper surface of the placement box 4 by a hinge 12. The upper surface of the second connecting frame 11 is installed on the lower surface of the flipping plate 13.

[0024] like Figure 3 As shown, an auxiliary spring 14 is installed on the upper surface of the support plate 2. The top end of the auxiliary spring 14 is installed on the lower surface of the placement box 4. The auxiliary spring 14 is sleeved on the outer surface of the adjusting column 3. An adjusting tube 17 is installed on the lower surface of the support plate 2. The outer surface of the adjusting column 3 passes through the adjusting tube 17. A reinforcing plate 15 is installed on the front side of the mounting plate 1. An adjusting pin 18 is threaded through the outer surface of the adjusting tube 17. One end of the adjusting pin 18, which is threaded into the adjusting tube 17, abuts against the adjusting column 3.

[0025] like Figure 5 As shown, a positioning frame 19 is mounted on the upper surface of the flip plate 13. A positioning post 20 is slidably connected inside the positioning frame 19. A positioning pin 21 is threaded through the upper surface of the positioning frame 19. One end of the positioning pin 21, threaded into the positioning frame 19, abuts against the positioning post 20. A connecting plate 22 is mounted on the inner side of the positioning post 20. An insertion groove 23 is formed inside the connecting plate 22. An insertion block 24 is slidably connected inside the insertion groove 23. The insertion block 24... Figure 5 Inside the bottom insertion slot 23, the inner side of the insertion block 24 is equipped with an installation frame 25, and the side of the installation frame 25 is equipped with a positioning plate 26. It should be noted that the length of the bent metal plate is not only the length of the flip plate 13. The length of the metal plate needs to be bent multiple times, so the length of the metal plate is greater than the length of the flip plate 13.

[0026] In this embodiment, as Figure 1 and Figure 2As shown, the mounting plate 1 is mounted with a support base 27 via a fixing pin 16. A support leg 28 is mounted on the lower surface of the support base 27, and a control box 29 is mounted on the upper surface of the support base 27. A bending mechanism 30 is mounted on the front of the control box 29. The bending mechanism 30 consists of a hydraulic cylinder, an upper bending plate, a lower bending seat, and a mounting frame. Both the control box 29 and the support base 27 have maintenance doors 31 hinged to their backs for inspection and maintenance of the device. The support base 27, support leg 28, control box 29, bending mechanism 30, and maintenance door 31 constitute a complete servo bending machine, which operates purely electrically.

[0027] Working principle: The mounting piece 1 is pressed against the support base 27 and fixed by the fixing pin 16, so that the support plate 2 is in contact with the support base 27. Place the metal plate on the upper surface of the flip plate 13. According to the thickness of the metal plate, manipulate the mounting frame 25 to slide the plug block 24 into the corresponding plug slot 23. Loosen the positioning pin 21 counterclockwise. Move the positioning column 20 inward along the positioning frame 19. The inward movement of the positioning column 20 drives the connecting plate 22 to move inward. The inward movement of the connecting plate 22 drives the plug block 24 to move inward. The inward movement of the plug block 24 drives the mounting frame 25 to move inward. The inward movement of the mounting frame 25 drives the positioning plate 26 to move inward. The inward movement of the positioning plate 26 fixes the metal plate. Then tighten the positioning pin 21 clockwise to press against the positioning column 20. Loosen the adjusting pin 18 counterclockwise, manipulate the adjusting column 3 to move upward along the inside of the adjusting tube 17, the upward movement of the adjusting column 3 drives the placement box 4 to move upward, the upward movement of the placement box 4 stretches the auxiliary spring 14, the upward movement of the placement box 4 drives the flipping plate 13 to move upward, the upward movement of the flipping plate 13 drives the metal plate to move upward, so that the upper surface of the metal plate is at the same level as the lower bending seat, and then the metal plate is inserted into the bending mechanism 30, and the bending mechanism 30 bends the metal plate. During this process, the metal plate tilts upward, causing the positioning plate 26 to flip upward, which in turn causes the mounting frame 25 to flip upward. The mounting frame 25 flips upward, which in turn causes the plug-in block 24 to flip upward. The plug-in block 24 flips upward, which in turn causes the connecting plate 22 to flip upward. The connecting plate 22 flips upward, which in turn causes the positioning post 20 to flip upward. The positioning post 20 flips upward, which in turn causes the positioning frame 19 to flip upward. The positioning frame 19 flips upward, which in turn causes the flipping plate 13 to flip upward along the placement box 4 via the hinge 12, preventing the metal plate from slipping after bending. At the same time, the flip plate 13 flips upward, causing the second connecting frame 11 to flip upward, so that the flip rod 10 rotates along the inside of the first connecting frame 9 and drives the first connecting frame 9 to move forward. The first connecting frame 9 moves forward, causing the second moving block 8 to move forward. The second moving block 8 moves forward, causing the first moving block 7 to move forward. The first moving block 7 moves forward along the buffer rod 5, and the first moving block 7 moves forward to compress the buffer spring 6. After the bending mechanism 30 releases the metal plate, the buffer spring 6 rebounds and drives the first moving block 7 to move backward along the buffer rod 5. The first moving block 7 moves backward and drives the second moving block 8 to move backward. The first moving block 7 moves backward and drives the first connecting frame 9 to move backward, so that the flipping rod 10 drives the second connecting frame 11 to flip downward and enter the placement box 4. At the same time, the metal plate, under the influence of gravity, together with the second connecting frame 11 pulls the flipping plate 13 to reset, completing the first bend. After the operator pushes the metal plate backward, subsequent bending processing is carried out.
