[0002] Instrument transformers are key devices used for current and voltage transformation and isolation in power systems. The quality of the transformer core directly affects the transformer's performance. The transformer core has specific shapes and dimensions, so it needs to be cut to meet different requirements during production.

[0003] However, existing cutting devices for producing transformer cores typically use a single cutting head for one shape. When producing cores of different shapes, different devices need to be used, and these devices are usually quite expensive. This increases production costs. Furthermore, changing devices for different shapes takes time, which reduces work efficiency.

[0004] Therefore, a cutting device for the production of current transformer cores is proposed to solve the problems mentioned above. Utility Model Content

[0023] 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.

[0024] Example:

[0025] Please see Figure 1 - Figure 4 A cutting device for producing transformer cores in this embodiment includes a base 1, a frame 2 fixedly connected to the top of the base 1, a workbench 3 fixedly connected to the top of the base 1, a movable plate 4 above the workbench 3, a hollow mounting plate 5 fixedly connected to the bottom of the movable plate 4, a limit block 6 slidably connected to the inner wall of the hollow mounting plate 5, and a cutting tool 7 fixedly connected to the bottom of the limit block 6.

[0026] The movable plate 4 is equipped with a replacement mechanism via the limiting block 6. The replacement mechanism includes at least two slide rods 8, springs 9, at least two baffles 10, at least two baffles 11, at least two slide rods 12, and at least two springs 13.

[0027] A sleeve 14 extends through the top of frame 2, and a transmission assembly is installed on frame 2 through sleeve 14;

[0028] When it is necessary to produce iron cores of different shapes and change different cutting tools 7, first press the two slide rods 12 closer to each other. Under the action of the changing mechanism, the two slide rods 12 will contact the two slide rods 8 and push the two slide rods 8 closer to each other until the two slide rods 8 leave the hollow mounting plate 5. Then the limiting block 6 can be removed from the hollow mounting plate 5. At this time, the cutting tool 7 is quickly changed.

[0029] At this point, the cutting tool 7 was quickly replaced. When faced with different production needs, different cutting tools 7 can be quickly replaced to meet different production needs. There is no need to set up multiple devices to meet different production needs, which reduces production costs. Moreover, the replacement of cutting tool 7 is relatively convenient and quick, which allows the device to be put into production more quickly and improves work efficiency.

[0030] Two sliding rods 8 are symmetrically distributed. One end of the sliding rod 8 passes through the side of the limiting block 6 and is slidably connected to the limiting block 6. The other end of the sliding rod 8 passes through the side of the hollow mounting plate 5 and is slidably connected to the hollow mounting plate 5.

[0031] Spring 9 is located inside the limiting block 6. The two ends of spring 9 are fixedly connected to the sides of the two slide rods 8 that are close to each other. The two baffles 10 are symmetrically distributed.

[0032] The top of baffle 10 is fixedly connected to the bottom of movable plate 4. Two baffles 21 are symmetrically distributed. The side of baffle 21 is fixedly connected to the side of baffle 10. Two sliding rods 22 are symmetrically distributed. The sliding rods 212 pass through the side of baffle 21 and are slidably connected to baffle 21.

[0033] The second slide rod 12 passes through one end of the second baffle 11 and passes through the first baffle 10, and is slidably connected to the first baffle 10. The second slide rod 12 is located on the side of the first slide rod 8. The radius of the first baffle 10 is smaller than the radius of the first slide rod 8. The two second springs 13 are symmetrically distributed. The second springs 13 are sleeved on the outer wall of the second slide rod 12. One end of the second spring 13 is fixedly connected to the side of the second baffle 11, and the other end of the second spring 13 is fixedly connected to the outer wall of the second slide rod 12.

[0034] When replacing the cutting tool 7, first press the two sliding rods 12 closer together. At this time, the two springs 13 are in a taut state. Since the radius of the sliding rod 12 is smaller than that of the sliding rod 8, after the sliding rod 12 contacts the sliding rod 8, continue pressing the sliding rod 12. The sliding rod 12 will drive the sliding rod 8 to slide inside the hollow mounting plate 5. The two sliding rods 8 will move closer together. After the two sliding rods 8 leave the hollow mounting plate 5, since the hollow mounting plate 5 and the limiting block 6 are slidably connected, the limiting block 6 can be removed from the hollow mounting plate 5 to replace the cutting tool 7 on the limiting block 6. Release the two sliding rods 12, and under the reset action of the two springs 13, the two sliding rods 12 will return to their original positions.

[0035] During installation, align the top of the limiting block 6 with the hollow mounting plate 5, then press the two sliding rods 8 closer together. At this time, the spring 9 is in a compressed state. After the two sliding rods 8 are retracted into the limiting block 6, the limiting block 6 is inserted into the hollow mounting plate 5. When it reaches the fixed position on the hollow mounting plate 5, the two sliding rods 8 will move away from each other under the action of the spring 9 until they are locked on the hollow mounting plate 5, thus fixing the position between the hollow mounting plate 5 and the limiting block 6.

[0036] At this point, the cutting tool 7 was quickly disassembled and installed, which was convenient and reduced the replacement time, allowing the equipment to be put into production more quickly and improving work efficiency.

[0037] The transmission assembly includes a rotating shaft 15 rotatably connected to the top of the frame 2, a gear 16 fixedly connected to the outer wall of the sleeve 14, a gear 17 fixedly connected to the outer wall of the rotating shaft 15, the gear 17 meshing with the gear 16, and a motor 18 disposed above the frame 2, the top of the rotating shaft 15 being fixedly connected to the output end of the motor 18.

[0038] A threaded rod 19 passes through the top of the sleeve 14 and is threadedly connected to the sleeve 14. The bottom of the threaded rod 19 is fixedly connected to the top of the movable plate 4. A guide rail 20 is fixedly connected to the inner wall of the frame 2. A slider 21 is slidably connected to the inner wall of the guide rail 20. The side of the slider 21 is fixedly connected to the side of the movable plate 4.

[0039] When cutting the iron core, the iron core is first placed on the worktable 3, and the motor 18 is started. The motor 18 will drive the rotating shaft 15 to rotate. At this time, because the gear 17 and the gear 16 are meshed, the sleeve 14 will also rotate when the rotating shaft 15 rotates. At this time, because the threaded rod 19 is threadedly connected to the sleeve 14, and the threaded rod 19 is fixedly connected to the moving plate 4, under the limiting action of the guide rail 20 on the slider 21, the threaded rod 19 will drive the moving plate 4 to move up and down due to the rotation of the sleeve 14. By controlling the rotation direction of the motor 18, the threaded rod 19 can drive the cutter 7 to cut the iron core on the frame 2.

[0040] At this point, the iron core is cut and processed, an operation that can be completed without manual intervention, thus improving the automation of the device.

[0041] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
