Description

Technical Field

[0001] This invention relates to the field of reactor processing technology, specifically a combined iron-core three-phase reactor and its winding device. Background Technology

[0002] A reactor, also called an inductor, is an electrical device that generates a magnetic field within a certain space when current flows through it. Therefore, all current-carrying conductors have inductance in a general sense. However, the inductance of a long, straight conductor is relatively small, and the magnetic field it produces is not strong. Therefore, practical reactors are made by winding wire into a solenoid, called air-core reactors. Sometimes, to give this solenoid a larger inductance, an iron core is inserted inside, called an iron-core reactor. Reactance is divided into inductive reactance and capacitive reactance. A more scientific classification is that inductors and capacitors are collectively called reactors. However, because inductors were developed first and were called reactors, the term "capacitor" now refers to a capacitive reactance, while "reactor" specifically refers to an inductor. During the manufacturing process of reactors, a winding device is needed to wind wire around the surface of the reactor core.

The device includes a base plate, an iron core, a wire spool, a clamping mechanism, and a tension monitoring mechanism.

Clamping frames are provided at both ends of the opening, and the two ends of the iron core are located inside the two clamping frames.

[0004] Based on the aforementioned patents and existing technologies, the reactors processed by the aforementioned devices are of a traditional parallel structure, which suffers from magnetic leakage on both sides, making it impossible to fully utilize the magnetic field generated by the coil cylinder. Furthermore, the aforementioned devices can only wind wires onto conventional cylindrical cores and cannot install the coil cylinder onto cores with special structures. Summary of the Invention

[0017] The beneficial effects of this invention are: (1) By setting the core and the spool in a ring array, the magnetic field generated by the spool is guided through the core, eliminating the leakage magnetic area and improving the working efficiency. The enameled wire that makes up the coil spool is released by the wire release assembly, the mountain-shaped core is clamped by the core loading assembly, the wire is wound into a coil spool by the winding assembly, and the coil spool is inserted into the middle protrusion of the mountain-shaped core by cooperating with the core loading assembly and the height limiting assembly. The height of the coil spool is limited by the height limiting assembly. The enameled wire is automatically separated from the wound coil spool by the switching assembly, and the wire end of the enameled wire is installed on the winding assembly before winding a new coil spool by the switching assembly. The automatic winding and installation of the spool component is realized, and the spool can be assembled for similar irregular cores, which improves the overall working efficiency. (2) During operation, the positions of the four winding positioning rods are adjusted according to the size of the different mountain-shaped cores of the coil square tube. During adjustment, the horizontal motor rotates the bidirectional horizontal screw to adjust the distance between the two second sliders, thereby adjusting the distance between the longitudinal adjustment boxes, thus adjusting the lateral distance between adjacent winding positioning rods. The longitudinal motor rotates the first key shaft, which is driven by the first bevel gear and the second bevel gear, and the two bidirectional longitudinal screws are rotated synchronously to adjust the distance between the two first sliders, thereby adjusting the longitudinal distance between adjacent winding positioning rods. This forms the core cross-sectional size required for different coil square tubes, automatically adapts to various cores, and can accurately produce coils with different cross-sectional sizes according to design requirements, thus improving the overall work efficiency. (3) During operation, the height limit rod is moved by the two second slides to flexibly adjust the height of the coil square tube. The wire is wiped in all directions by the wiping block to remove surface dust. After the coil square tube is wound, the fifth slide moves the L-shaped transmission frame so that the clamping block is directly above the wire. The wire is clamped by the clamping block and cut by the slitter. Then, the height limit rod clamps the coil square tube when the winding assembly moves until the mountain-shaped core is inserted into the hollow part of the coil square tube. After assembly, the clamping block clamps the wire and places it on the winding positioning rod with the connecting hook. The electromagnet is turned off, and the L-shaped transmission block is reset by the elastic force of the reset spring. The transmission sleeve is rotated in the opposite direction so that the connecting hook is turned out and hooks the wire. Then the clamping block is released from the wire and begins to wind from the inside to the outside to form a coil. When the first layer is wound, the electromagnet is started again to retract the connecting hook. This ensures that the coils of each layer of the coil square tube are tightly wound and that the wire is rotated in an orderly manner, thus ensuring the quality of the product.

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Please see Figure 1-9 As shown: A combined iron core type three-phase reactor includes a mountain-shaped core 601 and a coil square tube 602. The mountain-shaped core 601 is provided with three sets arranged in a ring array and abutting each other. The coil square tube 602 is sleeved on the protruding block in the middle of the mountain-shaped core 601. Mounting holes 603 for mounting bolts are opened on the abutting surfaces in the middle and on both sides of the mountain-shaped core 601.

[0022] A winding device for a combined iron-core three-phase reactor includes a winding assembly 100. A height limiting assembly 200, a core loading assembly 300, and a switching assembly 500 are sequentially arranged on one side of the winding assembly 100. A wire release assembly 400 is located on the same side of the winding assembly 100, height limiting assembly 200, core loading assembly 300, and switching assembly 500. The wire release assembly 400 releases the enameled wire forming the coil square tube 602. The core loading assembly 300 clamps the mountain-shaped core 601. The winding assembly... 100 winds the wire into a coil square tube 602, and in conjunction with the core assembly 300 and the height limiting assembly 200, inserts the coil square tube 602 into the middle protrusion of the mountain-shaped core 601. The height of the coil square tube 602 is limited by the height limiting assembly 200. The enameled wire is automatically separated from the wound coil square tube 602 by the switching assembly 500, and the end of the enameled wire is installed on the winding assembly 100 before winding a new coil square tube 602 by the switching assembly 500.

[0023] The winding assembly 100 includes a first slide table 101, a first mounting plate 102 is mounted on the sliding end of the first slide table 101, a winding motor 103 is mounted on the upper end of the first mounting plate 102 near the height limiting assembly 200, and a positioning circular plate 104 is mounted on the end of the drive shaft of the winding motor 103; An L-shaped mounting bracket 105 is installed on the upper side of the side surface of the positioning circular plate 104 near the height limiting component 200. Two transmission boxes 107 are slidably connected to the L-shaped mounting bracket 105. First sleeves 108 are inserted through and rotatably connected to both sides of the transmission boxes 107. First key shafts 109 are movably inserted through the coaxial axis of each first sleeve 108. The first sleeves 108 and the first key shafts 109 are keyed and slidably connected. One end of the first key shaft 109 is rotatably connected to the L-shaped mounting bracket 105, and a longitudinal motor 106 is installed at the other end of the first key shaft 109. The longitudinal motor 106 is installed on the L-shaped mounting bracket 105. Two longitudinal adjustment boxes 113 are arranged parallel and symmetrically in the middle of the side surface of the positioning circular plate 104 near the height limiting component 200. Each longitudinal adjustment box 113 is fixedly connected to the corresponding transmission box 107. A transmission shaft 111 is rotatably connected to the connection between the longitudinal adjustment box 113 and the transmission box 107. A second bevel gear 112 is fixedly connected to one end of the transmission shaft 111 inside the transmission box 107. A first bevel gear 110 is installed on the end face of one of the first sleeves 108 on the transmission box 107 inside the transmission box 107. The first bevel gear 110 and the second bevel gear 112 mesh and drive each other. A bidirectional longitudinal screw 114 is rotatably connected inside the longitudinal adjustment box 113. The upper end of the bidirectional longitudinal screw 114 is fixedly connected to the transmission shaft 111. A first slider 115 is threaded onto the threads on both sides of the bidirectional longitudinal screw 114. The first slider 115 is slidably connected to the longitudinal adjustment box 113. A winding positioning rod 116 is installed on the side surface of the first slider 115 near the height limiting component 200. A lateral adjustment box 117 is installed on the lower side of the side surface of the positioning circular plate 104 near the height limiting component 200. A bidirectional horizontal screw 118 is rotatably connected inside the lateral adjustment box 117. A lateral motor 119 is installed on one side of the lateral adjustment box 117. The drive shaft of the lateral motor 119 passes through the side of the lateral adjustment box 117 and is fixedly connected to the end of the bidirectional horizontal screw 118. A second slider 120 is threaded onto the threads on both sides of the bidirectional horizontal screw 118. The second slider 120 is fixedly connected to the longitudinal adjustment box 113. A limiting groove 121 is opened through the side of the lateral adjustment box 117 to slide and connect with the second slider 120. In this embodiment, the positions of the four winding positioning rods 116 are adjusted according to the different sizes of the mountain-shaped cores 601 placed in the coil square tube 602. During adjustment, the horizontal motor 119 rotates the bidirectional horizontal screw 118 to adjust the distance between the two second sliders 120, thereby adjusting the distance between the longitudinal adjustment boxes 113, thus adjusting the lateral distance between adjacent winding positioning rods 116. The longitudinal motor 106 rotates the first key shaft 109, which is driven by the first bevel gear 110 and the second bevel gear 112, synchronously rotating the two bidirectional longitudinal screws 114 to adjust the distance between the two first sliders 115, thereby adjusting the longitudinal distance between adjacent winding positioning rods 116. This forms the core cross-sectional size required for different coil square tubes 602, making it convenient to quickly insert the core into the spool after winding.

[0024] A mounting groove 701 is provided in the middle of the winding positioning rod 116, which is close to and above the wire feeding assembly 400. An electromagnet 702 is installed in the mounting groove 701 and on the side close to the first slider 115. A return spring 703 is installed on one side of the electromagnet 702. An L-shaped transmission block 704 is installed at the end of the return spring 703. A transmission iron block 705 is embedded in the end of the L-shaped transmission block 704 close to the return spring 703. A positioning shaft 706 is installed in the mounting groove 701 and above the horizontal section of the L-shaped transmission block 704. A transmission sleeve 707 is hinged on the positioning shaft 706. The outer periphery of the transmission sleeve 707 and the upper part of the horizontal section of the L-shaped transmission block 704 are provided with mutually meshing rack sets. A connecting hook 708 for hooking and fixing the enameled wire is installed on one side of the outer periphery of the transmission sleeve 707. A reset groove 709 is provided on the upper surface of the winding positioning rod 116 and above the connecting hook 708. In this embodiment, the transmission sleeve 707 and the L-shaped transmission block 704 are driven by mutual meshing. The transmission block 705 is attracted by the electromagnet 702, and the L-shaped transmission block 704 is moved in the direction of the electromagnet 702, causing the transmission sleeve 707 to rotate. This retracts the connected hook 708 into the mounting groove 701, facilitating the quick insertion of the core into the spool after winding. When rewinding the spool, the clamping block 504 clamps the wire and moves it above the mounting groove 701. At this time, the electromagnet 702 is turned off, and the L-shaped transmission block 704 is reset by the elastic force of the return spring 703. The transmission sleeve 707 is rotated in the opposite direction, causing the hook 708 to rotate out and hook the wire. Then the clamping block 504 is released from the wire, and the spool is wound layer by layer from the inside out. After the first layer is wound, the electromagnet 702 is activated again, and the hook 708 is retracted.

[0025] The height limiting component 200 includes a second slide 201. Two second slides 201 are provided and are centrally symmetrically connected to each other. A height limiting motor 202 and a second mounting plate 203 are respectively installed on both sides of the connection between the two second slides 201. A second key shaft 204 is installed on the drive shaft of the height limiting motor 202. The second key shaft 204 and the second mounting plate 203 are rotatably connected. Two second sleeves 207 are movably sleeved on the second key shaft 204. A transmission support plate 205 is installed on the sliding end of the second slide 201. A transmission bracket 206 is installed on the transmission support plate 205. The transmission bracket 206 is rotatably connected to the second sleeves 207. Parallel height limiting rods 208 are fixedly connected to the middle of the two second sleeves 207 on the same side. In this embodiment, the height of the coil square tube 602 is flexibly adjusted by moving the height limiting rod 208 through the two second slides 201. During winding, the height limiting motor 202 rotates the second key shaft 204, and the second key shaft 204 rotates the two second sleeves 207 synchronously, thereby synchronously controlling the position of the height limiting rod 208. After winding is completed, the height limiting rod 208 clamps the coil square tube 602 when the winding assembly 100 moves until the mountain-shaped core 601 is inserted into the hollow part of the coil square tube 602.

[0026] The core assembly 300 includes a third slide 301, a third mounting plate 302 is mounted on the sliding end of the third slide 301, a clamp 303 is mounted on the third mounting plate 302, and a positioning protrusion 304 for positioning is provided on the clamping block 504 of the clamp 303. In this embodiment, the positioning protrusion 304 engages with the mounting hole 603 to position the clamped mountain-shaped core 601, and the clamp 303 clamps the mountain-shaped core 601 more stably. After the coil tube 602 is wound, the first slide 101 and the third slide 301 cooperate, and the height limiting rod 208 limits the clamping of the coil tube 602, thus completing the insertion of the mountain-shaped core 601 and the coil tube 602.

[0027] The wire feeding assembly 400 includes a wire feeding support plate 401, a fourth mounting plate 402 is mounted on the wire feeding support plate 401, an enameled wire coil 403 is mounted on the middle of one side of the fourth mounting plate 402, a wire guide rod 404 and a fourth slide table 405 are respectively mounted on the upper part of one side of the fourth mounting plate 402, and a wire wiping block 406 is mounted on the lower part of the sliding end of the fourth slide table 405. In this embodiment, the wire released from the enameled wire roll 403 is released to the winding assembly 100 at the same height by the wire guide slide 404. The wire is wiped from all directions by the wire wiping block 406 to remove surface dust. The wire is moved back and forth by the fourth slide 405 at a distance equal to the height of the coil square tube 602, thereby winding the wire layer by layer in an orderly manner.

[0028] The switching assembly 500 includes a fifth slide 501, an L-shaped transmission frame 502 is mounted on the sliding end of the fifth slide 501, two switching push rods 503 are mounted on the horizontal section of the L-shaped transmission frame 502, a clamping block 504 is mounted on the telescopic end of the switching push rod 503 near the wire feeding assembly 400, and a slitting device 505 is mounted on the telescopic end of the other switching push rod 503. In this embodiment, the coil square tube 602 is wound, and then the fifth slide 501 moves the L-shaped transmission frame 502 so that the clamping block 504 is located directly above the wire. The wire is clamped by the clamping block 504 and cut by the cutter 505 to complete the winding of the coil square tube 602. After the coil square tube 602 and the mountain-shaped core 601 are assembled, the clamping block 504 clamps the wire and places it on the winding positioning rod 116 with the connecting hook 708. The connecting hook 708 is used to complete the handover operation of the wire end.

[0029] In summary, during operation, the core and spool are arranged in a ring array, ensuring that the magnetic field generated by the spool is guided through the core, eliminating magnetic leakage areas and improving work efficiency. The enameled wire that makes up the coil spool 602 is released by the wire release assembly 400, the mountain-shaped core 601 is clamped by the core loading assembly 300, and the wire is wound into the coil spool 602 by the winding assembly 100. The coil spool 602 is inserted into the middle protrusion of the mountain-shaped core 601 in cooperation with the core loading assembly 300 and the height limiting assembly 200. The height of the coil spool 602 is limited by the height limiting assembly 200. The enameled wire is automatically separated from the wound coil spool 602 by the switching assembly 500, and the wire end of the enameled wire is installed on the winding assembly 100 before winding a new coil spool 602. This achieves automatic winding and installation of the spool components and enables the assembly of spools for similar irregularly shaped cores, improving overall work efficiency. During operation, the positions of the four winding positioning rods 116 are adjusted according to the size of the different mountain-shaped cores 601 of the coil square tube 602. During adjustment, the horizontal motor 119 rotates the bidirectional horizontal screw 118 to adjust the distance between the two second sliders 120, thereby adjusting the distance between the longitudinal adjustment boxes 113, thus adjusting the lateral distance between adjacent winding positioning rods 116. The longitudinal motor 106 rotates the first key shaft 109, which is driven by the first bevel gear 110 and the second bevel gear 112, synchronously rotating the two bidirectional longitudinal screws 114 to adjust the distance between the two first sliders 115, thereby adjusting the longitudinal distance between adjacent winding positioning rods 116. This forms the core cross-sectional size required for different coil square tubes 602, automatically adapts to various cores, and can accurately produce coils with different cross-sectional sizes according to design requirements, thus improving the overall work efficiency. During operation, the height of the coil square tube 602 is flexibly adjusted by moving the height limiting rods 208 via the two second slides 201. The wire is wiped from all sides by the wiping block 406 to remove surface dust. After the coil square tube 602 is wound, the fifth slide 501 moves the L-shaped transmission frame 502, positioning the clamping block 504 directly above the wire. The clamping block 504 clamps the wire, and the wire is cut by the slitter 505. Subsequently, as the winding assembly 100 moves, the height limiting rods 208 clamp the coil square tube 602 until the mountain-shaped core 601 is inserted into the hollow part of the coil square tube 602. After assembly, the clamping... The holding block 504 clamps the wire and places it on the winding positioning rod 116 with the connecting hook 708. The electromagnet 702 is turned off, and the L-shaped transmission block 704 is reset by the elastic force of the return spring 703. The transmission sleeve 707 is rotated in the opposite direction, causing the connecting hook 708 to rotate out and hook the wire. Then the holding block 504 is released from the wire, and the wire begins to be wound layer by layer from the inside out to form a coil. When the first layer is wound, the electromagnet 702 is turned on again to retract the connecting hook 708. This ensures that the coils of each layer of the coil tube 602 are tightly wound and that the wire is rotated in an orderly manner, thus ensuring the quality of the product.

[0030] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
