Description

Technical Field

[0001] The present invention relates to the technical field of transformer manufacturing, and in particular to a winding device for a transformer core which is convenient to replace. Background Art

[0002] The field of transformer manufacturing technology encompasses transformer design, manufacturing, operation, and maintenance. Its core content is the design and manufacture of the transformer's electromagnetic system and mechanical structure based on the principle of electromagnetic induction. This encompasses a series of steps, from basic core and winding production to overall structural construction, insulation treatment, and performance testing. This ensures that the transformer can efficiently, stably, and safely achieve voltage conversion functions. It is widely used in power systems, industrial production, and various power consumption scenarios.

[0003] The easily replaceable winding device for transformer cores is specifically designed for coil winding during transformer core production. During transformer core production, the coils must be tightly and regularly wound around the core. This winding device typically uses a pay-off roller to position the copper wire to be wound. The winding machine's power structure drives the core or pay-off mechanism to achieve coil winding on the core. The device also features a structural design that facilitates the replacement of the pay-off roller, improving the continuity and efficiency of the winding process.

[0004] Although the winding device in the existing technology can realize coil winding and wire-paying roller replacement, it lacks an automated coordination mechanism in the iron core replacement link. The loading and unloading of the iron core relies on manual or simple mechanical assistance, which leads to the interruption of the processing flow during the replacement process, affecting continuous production. In addition, the iron core positioning stability is insufficient, and winding deviation is prone to occur, which reduces product quality and cannot meet the needs of efficient and continuous processing.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example 1: A winding device for a transformer core that is easy to replace, see Figure 1 and Figure 2 , including a base 1, a shell 2 arranged on the upper end of the base 1, an electric telescopic rod 4 symmetrically installed on the upper end of the shell 2, a discharge port 21 arranged on the front side of the shell 2 for outputting finished products, a maintenance door 22 arranged at the rear end of the shell 2 for installing wire raw materials, a feeding structure 3 connected to its inner cavity is provided at the upper end of the shell 2, an iron core replacement structure 5 for transporting and fixing the iron core is symmetrically provided on the left and right sides of the inner wall of the shell 2, and a winding structure 6 for winding is provided at the rear end of the upper end of the base 1.

[0035] During the operation of this embodiment, the bottom support assembly 51 of the core replacement structure 5 cooperates with the pressing assembly 52 to achieve bottom support and upper pressure on the core. The slide groove 23 of the outer shell 2 guides the bottom support assembly 51 to slide, and the guide assembly 53 limits the movement trajectory of the pressing assembly 52, ensuring that the core is stably suspended in front of the winding structure 6 for efficient winding. At the same time, the bottom support assembly 51 and the pressing assembly 52 cooperate with the electric telescopic rod 4 to remove the core from the cooperative unloading assembly 32 and transport it to the working range of the winding structure 6, thereby realizing quick replacement and continuous processing of the core, and the bottom support assembly 51 can send the wound core into the outlet 21, thereby improving processing efficiency and continuity.

[0036] For further information, see Figure 3 and Figure 4 The winding structure 6 includes a wire winding box 61 installed at the rear of the upper end of the base 1 adjacent to the maintenance door 22. The upper end of the wire winding box 61 is rotatably connected to a reciprocating screw 62 driven by a motor through a bracket. The outer surface of the reciprocating screw 62 is provided with a winder 63 that is slidably connected to the upper end of the wire winding box 61. The left and right ends of the wire outlet of the winder 63 are provided with motor-driven driving wheels 64. The wire outlet end of the winder 63 and the driving wheels 64 on both sides are in contact with the surface of the iron core.

[0037] The copper wire that needs to be wound around the iron core is stored in a wire reel box 61 arranged at the upper end of the base 1, and the reciprocating screw 62 drives the winder 63 to circulate on the surface of the iron core. While moving, the driving wheel 64 drives the iron core to rotate, thereby guiding the copper wire to be wound around the surface of the iron core. The winder 63 is a conventional winding device in the prior art, and its built-in wire device adheres the copper wire to the surface of the iron core and winds the copper wire around the surface of the iron core by rotating the iron core. Its specific structure and operating principle are conventional technical means in the prior art, and will not be displayed or elaborated on in the present invention.

[0038] Embodiment 2: Based on embodiment 1, this embodiment cooperates with the bottom support assembly 51 and the pressing assembly 52 of the core replacement structure 5 to achieve bottom support and upper pressure on the core. Combined with the slide groove 23 of the outer shell 2, the bottom support assembly 51 is guided to slide, and the guide assembly 53 limits the movement trajectory of the pressing assembly 52, ensuring that the core is stably suspended in front of the winding structure 6 for efficient winding; at the same time, the bottom support assembly 51 and the pressing assembly 52 cooperate with the electric telescopic rod 4 to remove the core from the cooperative unloading assembly 32 and transport it to the working range of the winding structure 6, thereby realizing quick replacement and continuous processing of the core, and the bottom support assembly 51 can send the wound core to the outlet 21, thereby improving processing efficiency and continuity.

[0039] For further information, see Figure 4The iron core replacement structure 5 includes a bottom support assembly 51 for supporting the edge of the iron core at the bottom, and a pressing assembly 52 is provided on the upper side of the bottom support assembly 51 and is suspended relative to the upper side of the iron core. The pressing assembly 52 is fixedly connected to the piston rod at the output end of the electric telescopic rod 4, and a guide assembly 53 for guiding the movement trajectory of the pressing assembly 52 is symmetrically provided on the front and rear side walls of the shell 2, and a slide groove 23 for guiding the sliding of the bottom support assembly 51 is symmetrically provided on the left and right sides of the middle part of the inner surface of the shell 2.

[0040] The bottom support assembly 51 is used to support the iron core at the bottom, cooperate with the pressing assembly 52 to limit the iron core, and make it suspend in front of the winding structure 6, so that the quota and the winding box 61 can wind it. Furthermore, during the unloading process, the wound iron core is sent to the discharge port 21 by the action of the bottom support assembly 51;

[0041] Furthermore, during the process of replacing the iron core, the bottom support assembly 51 supports the iron core at the bottom, and cooperates with the pressure of the pressing assembly 52 to remove the iron core from the cooperative unloading assembly 32, and cooperates with the pressing assembly 52 to transport the iron core to the range of action of the winding structure 6, thereby realizing quick replacement and continuous processing.

[0042] For further information, see Figure 5 The pressing assembly 52 includes a central block 524 fixedly connected to the piston rod at the output end of the electric telescopic rod 4. The front and rear ends of the central block 524 are symmetrically fixedly connected to sliders 521 through spring rods. The two sliders 521 are rotatably connected to the pulley 522 slidingly connected to the adjacent guide assembly 53 on the side close to the inner wall of the shell 2. The two sliders 521 are fixedly connected to the pressing wheel 523 for pressing the iron core on the side away from the inner wall of the shell 2. The lower end of the central block 524 is fixedly connected to a connecting rod 525 fixedly connected to the bottom support assembly 51, and the outer surface of the connecting rod 525 is provided with a buffer spring 526 fixedly connected to the bottom support assembly 51.

[0043] Through the action of the electric telescopic rod 4 and the center block 524, the slider 521 can be pulled to slide along the track restricted by the guide assembly 53 under the limit of the pulley 522. In the processing state, the electric telescopic rod 4 presses the center block 524 to prompt the slider 521 to move downward. During this process, the connecting rod 525 drives the base assembly 51 to move downward to the bottom, and the pressing wheel 523 presses on the edge of the iron core, thereby fixing the iron core.

[0044] For further information, see Figure 6 The bottom support assembly 51 includes a connecting block 512 that is slidably connected to the inner surfaces of the two slide grooves 23. The connecting block 512 is fixedly connected to a rectangular frame 511 on the side away from the slide groove 23. The inner surface of the rectangular frame 511 is symmetrically slidably connected to a cross bar 513 on the left and right sides. The inner surface of the rectangular frame 511 is symmetrically provided with connecting blocks 512 that are rotatably connected to the cross bars 513 on both sides.

[0045] The crossbar 513 and the connecting block 512 inside the rectangular frame 511 support the bottom of the core and, in conjunction with the vertical slot 532 , fix the core during the processing.

[0046] Example three. Based on Example two, this example cooperates with the rectangular frame 511, the cross bar 513, the vertical guide groove 516, and the arc-shaped guide groove 517 of the base support assembly 51, and combines the linkage of the push rod 514, the connecting plate 515 and the connecting rod 525 to realize automatic pushing out and unloading after the iron core winding is completed; at the same time, the L-shaped clamping plate 519 cooperates with the balloon 510 to realize the automatic release and reset of the connecting block 512 under the action of the connecting plate 515, and cooperates with the buffer spring 526 to ensure the stable operation of the structure, thereby realizing the overall automatic unloading and continuous operation of the iron core processing, improving the processing efficiency and operation convenience.

[0047] For further information, see Figure 6 and Figure 7 The upper part of the two vertical guide grooves 516 on the rear side is also provided with an arc guide groove 517. When the cross bar 513 is at the uppermost side of the vertical guide groove 516, the front vertical guide groove 516 is the axis for the cross bar 513 to rotate along the arc guide groove 517. The inner surface of the rectangular frame 511 is symmetrically slidably connected with the push rod 514 that is tightly attached to the lower side of the adjacent cross bar 513. The lower ends of the two push rods 514 penetrate the inner wall of the rectangular frame 511 and extend to the lower end of the rectangular frame 511 and are fixedly connected to the connecting plate 515. The upper end of the connecting plate 515 is elastically connected to the connecting block 512 by a buffer spring 526. The connecting rod 525 penetrates the connecting block 512 and extends to the lower end of the connecting block 512 and is fixedly connected to the connecting plate 515.

[0048] After the winding is completed, the connecting plate 515 is pulled by the connecting rod 525. Due to the limiting effect of the L-shaped clamping plate 519, the connecting block 512 and the rectangular frame 511 will not move in the initial stage of the movement. At this time, the pushing rod 514 moves upward relative to the rectangular frame 511, and pushes the cross bar 513 to move upward along the trajectory of the vertical guide groove 516. When the cross bar 513 moves to the top of the trajectory of the vertical guide groove 516, the pressing wheel 523 leaves the surface of the iron core. At this time, the front side of the cross bar 513 cannot continue to rise. Under the action of the pushing rod 514, the rear side of the cross bar 513 rotates along the arc guide groove 517 along the front vertical guide groove 516 as the axis, and pushes the iron core out of the rectangular frame 511, so that it enters the discharge port 21, realizing automatic unloading.

[0049] For further information, see Figure 7The inner wall of the slide groove 23 is slidably connected to an L-shaped card plate 519 through the mounting groove. The two vertical sides of the L-shaped card plate 519 extend through the slide groove 23 and fit on the upper end of the connecting block 512. The horizontal side of the L-shaped card plate 519 is provided with an arc-shaped spring piece 518. A balloon 510 is provided on the lower side of the inner wall of the shell 2. The L-shaped card plate 519 is connected to the mounting groove. When the connecting plate 515 rises, the balloon 510 is pressed so that the hydraulic oil inside it enters the mounting groove and pushes the L-shaped card plate 519 away from the connecting block 512 and releases it.

[0050] During the process of sending out the iron core, the connecting plate 515 will continue to squeeze the balloon 510 so that the hydraulic oil inside it enters the installation groove where the L-shaped card plate 519 is located, and push the L-shaped card plate 519 away from the connecting block 512 through oil pressure until the L-shaped card plate 519 is completely separated from the connecting block 512. Under the action of the connecting rod 525, the connecting block 512 will instantly lift and leave the range of the L-shaped card plate 519, and the waiter will follow the connecting rod 525 to lift under the action of the connecting rod 525 and the buffer spring 526, and contact the iron core in the cooperative blanking assembly 32.

[0051] Example 4. Based on Example 3, this example guides the pressing assembly 52 to move along a specific trajectory by cooperating with the vertical groove 532, V-shaped groove 531 of the guide assembly 53 and the paddle 1 533 and paddle 2 534, and realizes the lifting and spacing adjustment of the pressing assembly 52 in combination with the electric telescopic rod 4; at the same time, the feed hopper 31 of the feeding structure 3 cooperates with the center plate 321, wedge block 322, and arc-shaped support block 326 of the collaborative unloading assembly 32, and under the action of the pressing assembly 52 and the bottom support assembly 51, the intermittent unloading, precise transportation and continuous supply of the iron core are realized, ensuring the automation process of the iron core from feeding to entering the winding structure 6, and improving the processing continuity and efficiency.

[0052] For further information, see Figure 8 and Figure 9 The guide assembly 53 includes a vertical groove 532 that is vertically opened. The vertical groove 532 is within the range of the feeding structure 3. A V-shaped groove 531 is opened on the side of the vertical groove 532 away from the electric telescopic rod 4. The V-shaped groove 531 extends from the lower side of the feeding structure 3 to the side away from the electric telescopic rod 4 and returns from the upper side of the inner wall of the shell 2 to the upper side of the vertical groove 532. A paddle 1 533 is provided at the junction of the V-shaped groove 531 and the vertical groove 532 at the lower part to guide the pulley 522 to slide toward the V-shaped groove 531. A paddle 2 534 is provided at the junction of the V-shaped groove 531 and the vertical groove 532 at the upper part to guide the pulley 522 to slide along the vertical groove 532.

[0053] Its specific running trajectory is that it rises along the vertical track of the vertical groove 532 under the action of the electric telescopic rod 4 until it enters the V-shaped groove 531 through the guidance of the paddle 1 533 and continues to rise along the V-shaped groove 531. At this time, the pressing assembly 52 is outside the cooperative blanking assembly 32, and the spacing between the pressing assemblies 52 is greater than the diameter of the iron core.

[0054] Furthermore, two bare core pieces are stored in the cooperative blanking assembly 32. When the pressing assembly 52 moves to the uppermost side of the vertical slot 532, it is located between the two bare core pieces in the cooperative blanking assembly 32. At this time, the distance between the pressing assembly 52 is smaller than the diameter of the core piece. At the same time, the bottom support assembly 51 contacts the bottom of the bare core piece below, providing a virtual support for it.

[0055] The piston of the electric telescopic rod 4 extends, pressing the pressing assembly 52 downward. During this process, due to the obstruction of the second paddle 534, the pressing assembly 52 will not return to the V-shaped groove 531, but will descend along the vertical groove 532 path until it returns to its initial position. During this process, the pressing assembly 52 presses the iron core in the cooperative blanking assembly 32 to descend synchronously until it enters the range of the winding structure 6.

[0056] Furthermore, the core bare parts provided by the external conveying equipment are received by the feed hopper 31 and transported to the coordinated unloading assembly 32. The coordinated unloading assembly 32 is an intermittent unloading structure that cooperates with the bottom support assembly 51 and the pressing assembly 52. Figure 2 and Figure 3 The feeding structure 3 includes a feeding hopper 31 installed on the upper end of the shell 2. The feeding hopper 31 is provided with an I-shaped slot adapted to the shape of the iron core. The lower end of the feeding hopper 31 located in the inner cavity of the shell 2 is provided with a cooperative feeding component 32 that fits the surface of the inner shaft of the iron core.

[0057] For further information, see Figure 10 The collaborative blanking component 32 includes a center plate 321. The inner wall width of the center plate 321 is greater than the width of the iron core and four hydraulic grooves 323 are arranged in a rectangular distribution on the lower part of its inner surface. The inner surfaces of the four hydraulic grooves 323 are fixedly connected with compression springs 324. The four compression springs 324 are fixedly connected to the inner walls of adjacent hydraulic grooves 323 on one side close to the iron core. The distance between the wedge blocks 322 on the front and rear sides is less than the diameter of the iron core. Four piston grooves 325 connected to the adjacent hydraulic grooves 323 are arranged in a rectangular distribution on the upper side of the inner wall of the center plate 321. Piston rods are provided on the inner sides of the four piston grooves 325. The side of the piston rods close to the iron core is fixedly connected with an arc-shaped support block 326 that fits the surface of the iron core.

[0058] In the initial state, two bare cores are stored inside the center plate 321. The wedge-shaped block 322 extends under the action of the hydraulic groove 323, and the surface of the core overlaps the upper side of its slope. The arc-shaped support block 326 on its upper part also contacts the core synchronously to prevent the core from falling.

[0059] When the pressing assembly 52 moves downward, the wedge block 322 will be pressed by the iron core. Since the wedge block 322 is wedge-shaped, it will gradually retract into the hydraulic groove 323 during the force application until the limit on the iron core is completely released. At this time, the iron core will fall above the bottom support assembly 51 and continue to move downward with the bottom support assembly 51. At the same time, the iron core located on the upper side of the arc support block 326 will fall and stay above the pressing assembly 52, gradually descending with the descent of the pressing assembly 52 and finally restricted by the wedge block 322 to the inner side of the cooperative blanking assembly 32.

The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
