[0023] like Figure 1-4 As shown, a transformer core pressing device includes an operating platform 1, a support 2 connected to the top surface of the operating platform 1, a pressing cylinder 3 mounted on the top surface of the support 2, a piston rod of the pressing cylinder 3 extending downward and connected to a lifting frame 4, a pressing head 5 mounted on the bottom surface of the lifting frame 4, a first guide assembly mounted between the inner walls of the lifting frame 4 and the support 2, a first moving mechanism mounted on the top surface of the operating platform 1 and below the pressing head 5, a support base 10 mounted on the top surface of the first moving mechanism, a clamping mechanism mounted on the top surface of the support base 10, a second moving mechanism mounted in front of the support 2, a moving plate 15 mounted on the second moving mechanism, a third moving mechanism mounted on the moving plate 15, a moving frame 20 mounted on the third moving mechanism, a feeding mechanism mounted on the moving frame 20, and a temporary storage platform 24 connected to the top surface of the operating platform 1 and one side of the support base 10.

[0024] like Figure 2As shown, there are two first guide components, which are located on both sides of the lifting frame 4. The first guide component includes a first slide rail 6, which is connected to the inner wall of the bracket 2. A first slider 7 that matches the first slide rail 6 is connected to the lifting frame 4. During the process of the pressing cylinder 3 driving the lifting frame 4 to rise and fall, the first slider 7 slides along the first slide rail 6.

[0025] The first moving mechanism includes a first motor 8, which is mounted on the top surface of the operating platform 1. A first lead screw 9 is connected to the output shaft of the first motor 8. The first lead screw 9 is rotatably connected to the top surface of the operating platform 1 via a support, bearing, etc. A first moving block is threaded onto the first lead screw 9. The first moving block is connected to the bottom of the support base 10. Second guide components are provided on both sides of the first lead screw 9. The second guide components include a second slide rail 11, which is connected to the top surface of the operating platform 1. A second slider 12 that matches the second slide rail 11 is connected to the bottom surface of the support base 10.

[0026] During operation, the first motor 8 is started, which drives the first lead screw 9 to rotate. The rotation of the first lead screw 9 drives the first moving block to move, thereby driving the support seat 10 to move. During this process, the second slider 12 moves along the second slide rail 11.

[0027] The clamping mechanism includes two clamping cylinders 25 arranged symmetrically. The two clamping cylinders 25 are respectively installed on both sides of the top surface of the support base 10. The output end of the clamping cylinder 25 is connected to a fixing plate 26. During operation, the two clamping cylinders 25 drive the two fixing plates 26 to move closer to each other, clamping and fixing the transformer core to be pressed in the middle.

[0028] like Figure 1 As shown, the second moving mechanism includes a second motor 13, which is mounted in front of the bracket 2. A second lead screw 14 is connected to the output shaft of the second motor 13. The second lead screw 14 is rotatably connected to the front of the bracket 2 via a support, bearing, etc. A second moving block is threaded onto the second lead screw 14. The second moving block is connected to the rear of the moving plate 15. A third guide assembly is provided below the second lead screw 14. The third guide assembly includes a third slide rail 16, which is connected to the front of the bracket 2. A third slider 17 that matches the third slide rail 16 is connected to the rear of the moving plate 15.

[0029] During operation, the second motor 13 is started, which drives the second lead screw 14 to rotate. The rotation of the second lead screw 14 drives the second moving block to move, thereby moving the moving plate 15 from above the support base 10 to above the temporary storage platform 24 to unload the pressed transformer core. During this process, the third slider 17 moves along the third slide rail 16.

[0030] The third moving mechanism includes a third motor 18, which is mounted in front of the moving plate 15. A third lead screw 19 is connected to the output shaft of the third motor 18. The third lead screw 19 is rotatably connected to the front of the moving plate 15 via a support, bearing, etc. A third moving block is threaded onto the third lead screw 19. The third moving block is connected to the rear of the moving frame 20. A fourth guide assembly is provided on one side of the third lead screw 19. The fourth guide assembly includes a fourth slide rail 27, which is connected to the front of the moving plate 15. A fourth slider 28 that matches the fourth slide rail 27 is connected to the rear of the moving frame 20.

[0031] During operation, the third motor 18 is started, which drives the third lead screw 19 to rotate. The rotation of the third lead screw 19 drives the third moving block to move, thereby driving the moving frame 20 to move downward and place the pressed transformer core on the temporary storage platform 24. During this process, the fourth slider 28 moves along the fourth slide rail 27.

[0032] like Figure 4 As shown, the feeding mechanism includes two suction cups 23, which are connected to the bottom surface of the movable frame 20. An air pump 21 is connected to the top surface of the movable frame 20. The transition chamber 21 is connected to the suction cups 23 via a conveying pipe 22. The air pump 21 is existing technology and can be purchased externally; its specific structure will not be described here. During use, after the air pump 21 is started, it draws air from inside the suction cups 23 through the conveying pipe 22. As the air is drawn out, the gas pressure inside the suction cups 23 gradually decreases, creating a significant pressure difference with the external atmospheric pressure. The external atmospheric pressure presses the suction cups 23 tightly against the surface of the pressed transformer core, generating a strong suction force. When it is necessary to release the pressed transformer core, the vent valve can be opened to allow air to re-enter the suction cups 23, balancing the internal and external air pressures, thereby releasing the suction force and separating the suction cups 23 from the pressed transformer core.

[0033] The working process of this utility model is as follows:

[0034] First, the transformer core to be pressed is placed on the top surface of the support base 10. Two clamping cylinders 25 drive two fixing plates 26 to move closer to each other, clamping and fixing the transformer core to be pressed in the middle. Then, the first moving mechanism drives the support base 10 to move backward to below the pressing head 5. The pressing cylinder 3 drives the lifting frame 4 to descend, and the pressing head 5 descends to press the transformer core to be pressed.

[0035] After stamping is completed, the first moving mechanism drives the support base 10 to move forward; then, the third moving mechanism drives the moving frame 20 to move downward, using the suction cup 23 to pick up the pressed transformer core; then, the third moving mechanism drives the moving frame 20 and the pressed transformer core to lift upward; subsequently, the second moving mechanism drives the pressed transformer core from above the support base 10 to above the temporary storage platform 24; finally, the third moving mechanism drives the moving frame 20 to move downward, placing the pressed transformer core on the temporary storage platform 24.

[0036] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
