Description

TECHNICAL FIELD

[0001] The utility model relates to transformer corrugated sheet production device technical field, specifically, and relates to a kind of corrugated sheet forming machine unwinding device for transformer production. BACKGROUND

[0002] A transformer is an electrical device used to change the size of voltage, and its basic principle is to use electromagnetic induction phenomenon. The main components of a transformer include the primary coil, secondary coil and core. When the current of the primary coil changes, a magnetic field will be generated in the secondary coil, causing the magnetic flux of the secondary coil to change. The corrugated sheet of a transformer is an important component, and its main role is to improve the safety and stability of the transformer. First, the corrugated sheet can increase the mechanical strength and stiffness of the transformer. During normal operation, the transformer is subjected to various external forces, such as temperature changes, load changes, etc. The corrugated sheet can effectively disperse these external forces to prevent the transformer from being damaged due to overload. Secondly, the corrugated sheet can also improve the thermal efficiency of the transformer. Since the transformer generates a large amount of heat during operation, if the heat cannot be effectively dissipated, it will cause the transformer to overheat, affecting its normal operation. The corrugated sheet can increase the heat dissipation area of the transformer to improve its thermal efficiency, thereby prolonging its service life. Finally, the corrugated sheet can also reduce noise and improve the comfort of the transformer. Since the transformer generates noise during operation, it seriously affects people's life and work quality. The corrugated sheet can absorb noise, making the transformer quieter. The corrugated sheet of the transformer needs to use an unwinding device to clamp the steel coil during the forming process.

[0003] The weight of the corrugated sheet steel coil is relatively large, and it needs to be lifted by multiple people when placing it on the unwinding device. On the one hand, the weight of the steel coil is relatively large, and the labor loss is relatively large. On the other hand, during the manual handling process, it is easy to slip and fall, causing damage to the steel coil due to impact with the ground. Therefore, a corrugated sheet forming machine unwinding device for transformer production is proposed, which clamps the steel coil from both sides through two sets of clamping plates, and lifts the steel coil clamped inside the clamping plate through a rotatable rotating rod to solve the above problems.

[0027] Example 1

[0028] Reference Figs. 1-3 This is the first embodiment of the present invention, which proposes an unwinding device for a corrugated sheet forming machine for transformer production. The device includes a base frame 1, with a connecting rod 2 symmetrically slidably connected to one side of the base frame 1. A connecting plate 3 is fixedly connected to the top of the connecting rod 2. A clamping plate 4 is rotatably connected inside the connecting plate 3. A lifting component 5 is provided at the outer end of the clamping plate 4. The lifting component 5 includes a slider 501 slidably connected to the top of the connecting rod 2. A rotating rod 502 is rotatably connected between the slider 501 and the clamping plate 4. A support rod 503 is fixedly connected to the outer end of the slider 501. A sleeve rod 504 is sleeved on the outer end of the support rod 503. A lead screw 505 is threadedly connected inside the sleeve rod 504. The lead screw 505 is rotatably connected to the base frame 1. The purpose of this setup is to first rotate the screw 505 to make the clamping plate 4 rotate towards the bottom of the base frame 1 when placing the corrugated steel coil, so that the bottom of the clamping plate 4 is parallel to the ground. Two sets of clamping plates 4 are used to clamp the corrugated steel coil from both ends. The two sets of clamping plates 4 with adjustable spacing are suitable for corrugated steel coils of various lengths. Then, rotate the screw 505 to make the clamping plate 4 rotate towards the top of the base frame 1, thereby lifting the corrugated steel coil. This makes the operation simple and prevents the corrugated steel coil from falling and impacting the ground during manual handling, thus preventing damage.

[0029] Optionally, the clamping plate 4 has a circular slot inside, and the lifting assembly 5 also includes a clamping plate 506 rotatably connected to the center of the clamping plate 4. The clamping plate 506 is circular, and a guide groove 507 is provided at the outer end of the clamping plate 4, which communicates with the circular slot. The purpose of this arrangement is that the circular slot can easily clamp the corrugated steel coil, and the rotatable clamping plate 506 facilitates the rotation of the corrugated steel coil. During the discharge process, the two sides of the corrugated steel coil pass through the inside of the guide groove 507.

[0030] Example 2

[0031] Reference Figs. 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0032] Compared to embodiment 1, the top of the base frame 1 is fixedly connected to a connecting box 6. The outer end of the connecting box 6 is symmetrically provided with a sliding groove 7. A connecting plate 8 is slidably connected inside the sliding groove 7. The connecting plate 8 is located inside the connecting box 6. A threaded rod 9 is symmetrically rotatably connected inside the connecting box 6. The threaded rod 9 is threadedly connected to the connecting plate 8. The outer end of the threaded rod 9 is symmetrically provided with threads and is arranged in opposite directions. An outer plate 10 is fixedly connected to one side of the connecting box 6. A first gear 11 and a second gear 12 are rotatably connected inside the outer plate 10. There are two second gears 12 and they are fixedly connected to the threaded rod 9. The first gear 11 and the second gear 12 mesh with each other. A servo motor 13 is fixedly connected to the outer end of the outer plate 10. The output end of the servo motor 13 is fixedly connected to the first gear 11. The purpose of this setup is that, when adjusting the distance between the two sets of clamping plates 4, the servo motor 13 drives the first gear 11 to rotate inside the outer plate 10. The rotating first gear 11 drives the two second gears 12 to rotate in the same direction, thereby causing the two threaded rods 9 to rotate. The rotating threaded rods 9 cause the connecting plate 8 to drive the connecting plate 3 to slide in opposite directions in the slide groove 7 at the outer end of the connecting box 6, thereby causing the two sets of clamping plates 4 to move in opposite directions, and thus changing the distance between the two sets of clamping plates 4.

[0033] Optionally, side rods 14 are symmetrically fixedly connected to the other side of the base frame 1. Guide rollers 15 are rotatably connected between the two sets of side rods 14. There are two guide rollers 15. Connecting grooves 16 are opened inside the side rods 14. There are two sets of connecting grooves 16. A stop block 17 is slidably connected inside the connecting groove 16. The guide rollers 15 and the stop blocks 17 are rotatably connected. A spring 18 is fixedly connected between the top of the connecting groove 16 and the stop block 17. The purpose of this arrangement is that when the corrugated sheet is pulled out, the steel sheet passes through the two sets of guide rollers 15. At this time, the elastic force generated by the spring 18 enhances the squeezing strength of the guide rollers 15 on the corrugated sheet, so that the corrugated sheet is pulled out stably.
