Description

Technical Field

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

[0002] The transformer core is the main magnetic circuit component of a transformer. It is typically made of stacked hot-rolled or cold-rolled silicon steel sheets with a high silicon content and an insulating varnish coating. The core and the coils wound around it form a complete electromagnetic induction system. The power transmitted by a power transformer depends on the material and cross-sectional area of ​​the core. Therefore, cutting equipment is required during the processing of transformer cores.

[0003] Existing transformer core cutting devices typically use a motor to drive a high-speed rotating cutter to cut the transformer core. For example, utility model patent CN221134265U discloses a transformer core cutting device, including a frame and a conveyor belt. The conveyor belt is installed inside the frame, and a support frame is installed on the top side of the frame. A pressure roller is elastically installed inside the support frame, and sliding arms are slidably installed at both ends of the support frame. A lifting seat is movably installed on the bottom side of the sliding arms. The movable block moves up and down along the guide column, and under the action of the spring, it ensures that the pressure roller presses on the top side of the core, which restricts the conveying and cutting of the core, avoids core wrinkles and deviation, and ensures cutting accuracy.

[0004] The aforementioned iron core cutting device, while improving cutting efficiency by simultaneously cutting both sides of the iron core with two cutters and ensuring cutting accuracy by adjusting the cutter in the center, generates a large amount of debris and dust during the cutting process. Without protective mechanisms, the flying debris and drifting dust not only pollute the surrounding environment but also endanger the health of workers.

[0005] Therefore, it is necessary to develop a transformer core cutting device to address the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a cutting device for transformer cores that can process the dust and debris generated during cutting, thereby preventing dust from scattering and debris from flying.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses a transformer core cutting device, including a cutting seat, with support plates slidably connected to both sides of the cutting seat, and a horizontal plate fixedly connected between the top ends of the two support plates; a cutting assembly is slidably connected to the bottom surface of the horizontal plate, and a positioning element is provided on the top surface of the cutting seat; dust suction hoods are provided on the two opposite side walls of the two support plates, and the dust suction hoods are connected to a processing box via hoses, and the processing box is connected to a suction fan; baffles are rotatably connected to both ends of the top surface of the horizontal plate, and the baffles are in contact with the side walls of the support plates in a vertical state.

[0008] Furthermore, the cutting seat is hollow inside and has through-holes on both sides. A first lead screw is rotatably connected to the inner cavity of the cutting seat, and a first threaded sleeve is threaded onto the first lead screw. The first threaded sleeve is slidably connected to the bottom surface of the inner cavity of the cutting seat. Connecting rods are fixedly connected to both sides of the first threaded sleeve. The connecting rods pass through the through-holes and are slidably connected to them. The support plate is fixedly connected to the connecting rods. A first motor is fixedly connected to the outer wall of the cutting seat. The first motor is coaxially fixedly connected to the first lead screw.

[0009] Furthermore, a slider is fixedly connected to the bottom surface of the first threaded sleeve, and a slide rail is fixedly connected to the inner bottom surface of the cutting seat, with the slider slidingly connected to the slide rail.

[0010] Furthermore, the cutting assembly includes a first telescopic member, the telescopic end of which is fixedly connected to a mounting plate, the bottom surface of which is fixedly connected to a second motor, and the output end of the second motor is coaxially fixedly connected to a cutter.

[0011] Furthermore, the horizontal plate has a groove along its length, and a second lead screw is rotatably connected in the groove. A second threaded sleeve is threaded onto the second lead screw, and the second threaded sleeve is slidably connected in the groove. A third motor is fixedly connected to one side wall of the horizontal plate. The third motor is coaxially fixedly connected to one end of the second lead screw, and the first telescopic member is fixedly connected to the second threaded sleeve.

[0012] Furthermore, the positioning component includes two second telescopic components, which are symmetrically fixed at both ends of the top surface of the cutting seat, and the telescopic ends of the second telescopic components are fixedly connected to clamps.

[0013] Furthermore, a filter screen is detachably connected inside the processing box, and the hose and the suction fan are respectively located on both sides of the filter screen at their communication points with the processing box.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This invention utilizes a dust collection hood installed on the side wall of a support plate, along with a hose, a processing box, and a suction fan to form a complete dust removal mechanism. The suction fan generates negative pressure during operation, allowing the dust collection hood to collect dust from the cutting area. The dust is then transported via the hose to the processing box for storage or filtration, effectively preventing dust dispersion and reducing environmental pollution at its source, while also protecting the health of workers. Simultaneously, a baffle is rotatably connected to the top surface of the horizontal plate. When the baffle is vertical, it contacts the side wall of the support plate, forming a physical protective barrier around the cutting area. This prevents debris from splashing outwards, reducing safety hazards to workers and minimizing the area of ​​debris dispersion, facilitating subsequent cleaning operations.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

Therefore, they should not be construed as limitations on this utility model.

[0021] It is understood that all electrical components mentioned in this article are electrically connected to the main controller and power supply, and all electrical components mentioned in this article are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices. Therefore, this utility model will not explain the control method and circuit connection in detail. At the same time, all parts not described in detail in this utility model are common technologies known to those skilled in the art.

[0022] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the device includes a cutting base 1, with support plates 2 slidably connected to both sides of the cutting base 1. A horizontal plate 3 is fixedly connected between the top ends of the two support plates 2. A cutting assembly is slidably connected to the bottom surface of the horizontal plate 3, and a positioning component is provided on the top surface of the cutting base 1. Dust hoods 4 are provided on the two opposite side walls of the two support plates 2. The dust hoods 4 are connected to a processing box 6 via a flexible hose 5, which is a PVC corrugated pipe. A suction fan 23 is connected to the processing box 6. Baffles 7 are rotatably connected to both ends of the top surface of the horizontal plate 3. When the baffles 7 are vertical, they are in contact with the side walls of the support plates 2. The baffles 7 are made of transparent PC board and are rotatably connected to the horizontal plate 3 via hinges.

[0023] The transformer core to be cut is fixed by positioning components, and the cutting assembly cuts the core. The suction fan 23 creates negative pressure in the dust hood 4, drawing the cutting debris and dust through the hose 5 into the processing box 6 for filtration. When placed vertically, the baffle 7 works in conjunction with the support plate 2 to form a protective barrier, preventing debris from splashing. These three components work together to address the shortcomings of existing devices, such as lack of protection and high pollution levels.

[0024] In one specific embodiment of this utility model, such as Figure 1 and Figure 2As shown, the cutting seat 1 is hollow inside with slotted holes on both sides. A first lead screw 8 is rotatably connected to the inner cavity of the cutting seat 1. A first threaded sleeve 9 is threaded onto the first lead screw 8 and slidably connected to the bottom surface of the inner cavity of the cutting seat 1. Connecting rods 10 are fixedly connected to both sides of the first threaded sleeve 9, passing through the slotted holes and slidably connected thereto. The support plate 2 is fixedly connected to the connecting rods 10. A first motor 11 is fixedly connected to the outer wall of the cutting seat 1, and the first motor 11 is coaxially fixedly connected to the first lead screw 8.

[0025] The first motor 11 drives the first lead screw 8 to rotate, and the first threaded sleeve 9 slides along the axial direction of the first lead screw 8. The connecting rod 10 drives the support plate 2 to slide along the strip hole, thereby driving the cutting assembly to move and realize the cutting of different positions of the transformer core.

[0026] Specifically, a slider 12 is fixedly connected to the bottom surface of the first threaded sleeve 9, and a slide rail 13 is fixedly connected to the inner bottom surface of the cutting seat 1. The slider 12 is slidably connected to the slide rail 13.

[0027] The sliding block 12 and the slide rail 13 form a precise sliding pair, which limits the first threaded sleeve 9 to move only along the axial direction of the first lead screw 8, and prevents the first threaded sleeve 9 from rotating with the first lead screw 8.

[0028] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the cutting assembly includes a first telescopic member 14, with a mounting plate 15 fixedly connected to the telescopic end of the first telescopic member 14. A second motor 16 is fixedly connected to the bottom surface of the mounting plate 15, and a cutter 17 is coaxially fixedly connected to the output end of the second motor 16. The first telescopic member 14 can be an electric push rod.

[0029] The first telescopic component 14 moves the mounting plate 15 up and down, adjusting the distance between the cutter 17 and the iron core. The second motor 16 drives the cutter 17 to rotate at high speed, cutting the iron core as it descends.

[0030] Specifically, the horizontal plate 3 has a groove 18 along its length, and a second lead screw 19 is rotatably connected within the groove 18. A second threaded sleeve 20 is threaded onto the second lead screw 19 and slidably connected within the groove 18. A third motor 24 is fixedly connected to one side wall of the horizontal plate 3. The third motor 24 is coaxially fixedly connected to one end of the second lead screw 19. The first telescopic member 14 is fixedly connected to the second threaded sleeve 20.

[0031] The second lead screw 19 is driven to rotate by the third motor 24, and the second threaded sleeve 20 slides along the slide groove 18, which drives the cutting assembly to move along the length of the horizontal plate 3. The cutting position can be positioned according to the required cutting size of the iron core, realizing multi-segment cutting or processing of iron cores of different lengths, and improving cutting flexibility.

[0032] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the positioning component includes two second telescopic components 21, which are symmetrically fixed at both ends of the top surface of the cutting seat 1. The telescopic ends of the second telescopic components 21 are fixedly connected to clamping plates 22. The second telescopic components 21 can be pneumatic cylinders, and rubber pads are attached to the side walls of the two clamping plates 22 facing each other.

[0033] The second telescopic component 21 pushes the clamping plate 22 towards the iron core, and the two clamping plates 22 work together to clamp the iron core to prevent the iron core from shifting during cutting; the rubber pad increases the friction with the iron core to avoid excessive clamping force from damaging the insulating varnish on the surface of the iron core, while also adapting to the clamping requirements of iron cores of different thicknesses.

[0034] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a filter screen 25 is detachably connected inside the treatment box 6. The hose 5 and the suction fan 23 are located on both sides of the filter screen 25, respectively, and communicate with the treatment box 6. The inner wall of the treatment box 6 is provided with a slot that fits the frame of the filter screen 25. The filter screen 25 is detachably connected to the treatment box 6 through the slot, which facilitates cleaning and replacement.

[0035] With the filter screen 25 in place, the debris and dust sucked in by the dust hood 4 enter the processing box 6, are filtered by the filter screen 25, and then discharged by the suction fan 23.

[0036] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
