Description

Technical Field

[0001] This utility model relates to the field of transformer core technology, and more specifically, to a transformer core cutting device. Background Technology

[0002] The transformer core is the core component of the transformer structure. It is mainly made of silicon steel sheets. The main function of the core is to provide a closed magnetic circuit, enabling the primary and secondary coils of the transformer to efficiently transmit electromagnetic energy. By concentrating magnetic lines of force and reducing leakage flux, the core helps to reduce the energy loss of the transformer. The core also provides necessary structural support for the transformer coils and other components.

[0003] Patent CN212329894U discloses a corner cutting device for transformer core processing, including a body and a fixed column. Cutting wheels are installed on the top of both ends of the body, and upper platforms are mounted on the upper walls of both ends. Side storage mechanisms are installed on both sides of the body. This invention allows for threaded transmission of the slot block by rotating a screw, changing the position of the slot block and displacing the end of the slot block. This facilitates better adjustment of the end for use. When the end moves down, it can easily engage with the clamp at the bottom of the central column, clamping the end of the core for easier processing and greater flexibility. Simultaneously, an arc clamp is movable at the arc opening. The arc clamp design has two clamps, one flat and one with concave teeth, allowing for easy switching and orientation to clamp different end faces, improving its gripping strength and stability.

[0004] While this device offers numerous benefits, it still presents the following challenges: The corner cutting device features two arc-shaped clamps, one flat and one with concave teeth, allowing for easy reversal and switching to clamp different end faces, thus improving its grip and stability. However, the transformer core, the main magnetic circuit component of a transformer, is typically constructed from stacked silicon steel sheets with a high silicon content and relatively thin thickness. During the stacking process, various factors (such as the shape of the silicon steel sheets themselves and the stacking operation) can lead to unevenness between the sheets. This unevenness can negatively impact the performance and stability of the transformer core. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A transformer core cutting device includes an operating table 1. Two symmetrically distributed support plates are fixedly connected to the top of the operating table 1. An adjustable flattening assembly is provided between the two support plates. The adjustable flattening assembly includes a first flattening roller 4, a second flattening roller 5, a screw 12, and a transition block 14. The transition block 14 is slidably connected inside both support plates. The first flattening roller 4 is rotatably connected between the two transition blocks 14. Two second flattening rollers 5 are rotatably connected between the two support plates. The first flattening roller 4 is located between and above the two second flattening rollers 5. A screw 12 is rotatably connected to the top of both support plates. The ends of the two screws 12 are fixedly connected to the tops of the corresponding transition blocks 14. Limiting components are provided on the outer surfaces of the two transition blocks 14 that are close to each other. The first flattening roller 4 is located between and above the two second flattening rollers 5. By adjusting the rotation of the screw 12, the height of the transition block 14 and the first flattening roller 4 can be changed, thereby achieving the flattening of cores of different thicknesses.

[0027] Furthermore, the adjustable flattening assembly also includes sprockets 6, chains 7, and a second motor 13. Two sprockets 6 are rotatably connected to the outer surface of one support plate, and chains 7 are meshed between the two sprockets 6. The second motor 13 is fixedly installed on the outer surface of the other support plate. The output end of the second motor 13 is fixedly connected to the adjacent second flattening roller 5. The two sprockets 6 are fixedly connected to the corresponding second flattening roller 5. When the second motor 13 is started, the output end of the second motor 13 drives the second flattening roller 5 fixedly connected to it to rotate. Since the two sprockets 6 are meshed with the chains 7 and the sprockets 6 are fixedly connected to the corresponding second flattening roller 5, when one second flattening roller 5 rotates, it will drive the other second flattening roller 5 to rotate synchronously.

[0028] Furthermore, two first fixed blocks are fixedly connected to the top of the operating table 1, and a winding roller 2 is rotatably connected between the two first fixed blocks. A first motor 3 is fixedly installed on the outer surface of one of the fixed blocks, and the output end of the first motor 3 is fixedly connected to the winding roller 2. Two second fixed blocks are fixedly connected to the top of the operating table 1, and a third flattening roller 21 is rotatably connected between the two second fixed blocks. An adjustable flattening assembly is located between the first fixed blocks and the second fixed blocks. When the first motor 3 is started, the first motor 3 drives the winding roller 2 to rotate, thereby winding up the transformer core.

[0029] Furthermore, a support frame is fixedly connected to the top of the operating table 1. The support frame is arranged in a "U" shape. Two symmetrically distributed limit blocks 11 are slidably connected to the outer surface of the support frame. An installation block 9 is fixedly connected between the two limit blocks 11. A cutting blade 10 is fixedly installed at the bottom of the installation block 9. A cylinder 8 is fixedly installed at the top of the support frame. The output end of the cylinder 8 is fixedly connected to the installation block 9. The output end of the cylinder 8 drives the installation block 9 and the cutting blade 10 to move downward to cut the iron core.

[0030] Furthermore, the limiting assembly includes a housing 15, a rack 16, and a limiting plate 17. The housing 15 is fixedly connected to the outer surface of the adapter block 14. The housing 15 is located between the first flattening roller 4 and the second flattening roller 5. The rack 16 is slidably connected inside the housing 15. The limiting plate 17 is fixedly connected to the outer surface of the rack 16. The limiting plate 17 is arranged in a "U" shape. The two limiting plates 17 can guide transformer cores of different widths.

[0031] Furthermore, a housing 18 is fixedly connected to the top of the housing 15. Two worm gears 20 are rotatably connected inside the housing 18, and a worm 19 is rotatably connected inside the housing 18. The worm 19 is located above the two worm gears 20 and meshes with them. The two worm gears 20 mesh with a rack 16, allowing the worm 19 to rotate. The worm 19 meshes with the two worm gears 20, and the worm gears 20 mesh with the rack 16, thereby driving the rack 16 and the limiting plate 17 to move.

[0032] Furthermore, a laser rangefinder 22 is fixedly installed between the support frame and one of the second fixed blocks. The cylinder 8 can be activated based on the data from the laser rangefinder 22, thereby enabling cutting to the required length.

[0033] Working principle: When the operator needs to use the transformer core cutting device, the first motor 3 is started first. The first motor 3 drives the winding roller 2 to rotate, thereby winding the transformer core. When the wound transformer core needs to be cut, the end of the wound transformer core can be pulled to pass between the first flattening roller 4 and the second flattening roller 5. The second motor 13 is started, and the output end of the second motor 13 drives the second flattening roller 5, which is fixedly connected to it, to rotate. Since the two sprockets 6 are connected by a chain 7 and the sprockets 6 are fixedly connected to the corresponding second flattening rollers 5, when one second flattening roller 5 rotates, it will drive the other second flattening roller 5 to rotate synchronously. The first flattening roller 4 is located between the two second flattening rollers 5 and above them. By adjusting the rotation of the screw 12, the height of the adapter block 14 and the first flattening roller 4 can be changed, thereby achieving... For flattening transformer cores of different thicknesses, to prevent positional shift during the pulling process, the worm gear 19 can be rotated when flattening transformer cores of different widths. The worm gear 19 meshes with two worm wheels 20, which in turn mesh with a rack 16, thereby driving the rack 16 and the limiting plate 17 to move. This allows the two limiting plates 17 to guide transformer cores of different widths. After the core passes the third flattening roller 21, it enters the cutting area. At this time, the cylinder 8 is activated. The output end of the cylinder 8 drives the mounting block 9 and the cutting blade 10 to move downwards to cut the core. The movement path of the cutting blade 10 is limited by the limiting block 11 on the support frame to ensure the accuracy and stability of the cutting. The laser range sensor 22 monitors the position and thickness of the core in real time. The cylinder 8 can be activated based on the data from the laser range sensor 22, and the required length can be cut.
