Description

Technical Field

[0001] The invention belongs to the technical field of iron core winding, and in particular relates to a winding device for a transformer iron core. Background Art

[0002] The transformer core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with insulating paint. The core and the coil wound on it form a complete electromagnetic induction system. The power transmitted by the power transformer depends on the material and cross-sectional area of ​​the core.

[0003] The production of transformer core is divided into stacked core and rolled core. Stacked core is made by processing silicon steel strip into silicon steel sheets of a certain shape through longitudinal shearing production line and transverse shearing production line, and then stacking the silicon steel sheets in a certain way;

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0050] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0051] See also Figures 1 to 17 As shown, the present invention provides a winding device for a transformer core, comprising a fixed base 1, through which the fixed base 1 provides fixation and support for the entire device;

[0052] The upper part of the fixed base 1 is fixedly connected with a winding part 2, through which one end of the core bar is fixed, and the core bar is rotated and wound into a whole;

[0053] The outer edge of the other end of the winding rod 202 is slidably provided with a discharge portion 3, and the discharge portion 3 can discharge the wound product of the iron core from the end of the winding portion 2 for falling off;

[0054] The discharge part 3 includes a discharge motor 301, a discharge screw 302, a rotating gear ring 303, a rotating cylinder 304, a sliding cylinder 305, and a limiting seat 306. The discharge motor 301 is fixedly connected to the upper part of the fixed base 1, and the discharge motor 301 is electrically connected to the control computer. One end of the discharge screw 302 is fixedly connected to the output end of the discharge motor 301, and the other end of the discharge screw 302 is rotatably connected to the inside of the fixed base 1. The outer edge of the rotating gear ring 303 is meshed with the outer edge of the discharge screw 302, and the outer edge of the rotating cylinder 304 is fixedly connected to the inner side of the rotating gear ring 303. The sliding cylinder 305 is slidably arranged on the outer edge of the rotating cylinder 304, and one end of the limiting seat 306 is slidably connected to the inside of the sliding cylinder 305, and the other end of the limiting seat 306 is fixedly connected to the inside of the upper end of the fixed base 1.

[0055] The upper part of the fixed base 1 is also provided with an extrusion part 4, through which the iron core bar wound on the outer edge of the winding rod 202 is extruded, so that the iron core bar and the winding rod 202 are more closely fitted, thereby increasing the tightness of the iron core bar wound on the winding rod 202 and improving the winding quality of the finished product:

[0056] A feeding portion 5 is also provided on the upper portion of the fixed base 1, through which the core bars are transported to the winding portion 2 for feeding and transportation;

[0057] One end of the feeding part 5 is provided with a docking part 6, through which the core bars conveyed by the feeding part 5 are limited and guided so that the core bars can be accurately inserted into the winding rod 202; at the same time, the docking part 6 can also cut the core bars.

[0058] Specifically, one end of the core bar is fixedly conveyed through the inside of the feeding part 5, and then extended to the winding rod 202 through the docking part 6, so that the docking part 6 squeezes the fixed block 203, so that the fixed block 203 shrinks and enters the inside of the winding rod 202, and then the feeding part 5 conveys the core bar, so that the core bar enters the inside of the winding rod 202 along the inside of the docking part 6, and then the docking part 6 resumes contraction, at this time, the fixed block 203 loses the squeezing and is squeezed out by the elastic locking piece 204, so that one end of the core bar is fixed between the winding rod 202 and the fixed block 203, and then the winding motor 201 drives the winding rod 202 to rotate, so as to drive the core bar to be wound;

[0059] It should be noted that when the core bar is wound, the core bar is first rotated along the winding rod 202 for one circle, and the core bar is initially fixed and welded by a corresponding welding device on one side;

[0060] While the core bar is being wound, the extrusion part 4 always applies pressure in the direction of the winding rod 202, so that the core bar is more closely attached to the outer edge of the winding rod 202, thereby increasing the tightness of the core bar wound on the winding rod 202 and improving the winding quality of the core bar finished product;

[0061] When the winding of the core strip is about to be finished, the edge is fixed and sealed by the welding device. Then, the output end of the discharge motor 301 drives the discharge screw 302 to rotate. The rotation of the discharge screw 302 drives the rotating gear ring 303, the rotating cylinder 304 and the extrusion plate 406 to rotate together. At this time, the first stage rotation of the rotating cylinder 304 does not squeeze the sliding cylinder 305. At this time, the sliding cylinder 305 is in a stationary state; the rotation of the extrusion plate 406 is in the first stage, and the rotation of the extrusion plate 406 can squeeze the sliding seat 402, so that the sliding seat 402 moves along the inside of the guide plate 401 in the direction away from the winding rod 202, and the sliding seat 402 gradually drives the extrusion seat 403 away from the outer edge of the winding rod 202, so that the finished core strip wound on the outer edge of the winding rod 202 loses the extrusion of the extrusion seat 403;

[0062] The rotation of the extrusion plate 406 is in the first stage, at which the extrusion plate 406 squeezes the sliding seat 402 away from the winding rod 202 at the maximum distance. As the extrusion plate 406 continues to rotate, the extrusion seat 403 does not squeeze the sliding seat 402, so that the sliding seat 402 is in the second stage of stopping; the rotation of the rotating cylinder 304 is in the second stage, and at the same time, the rotation of the rotating cylinder 304 can squeeze the sliding cylinder 305. At this time, the sliding cylinder 305 moves along the winding rod 202 toward the outside of the fixed base 1, so that the sliding cylinder 305 can squeeze the finished iron core bar wound on the outer edge of the winding rod 202, so that the finished product falls off the outer edge of the winding rod 202, and the falling off of the finished iron core bar is completed;

[0063] Then the discharge motor 301 rotates in the opposite direction, so that the sliding cylinder 305 is squeezed by the rotating cylinder 304 and shrinks into the interior of the fixed base 1 to expose the winding rod 202; then the sliding seat 402 is squeezed by the squeezing disk 406 and moves toward the direction of the winding rod 202, so that the squeezing seat 403 drives the squeezing column 405 to contact the winding rod 202, and the squeezing force is always applied to the squeezing seat 403 through the elastic squeezing member 404.

[0064] See also Figure 8 As shown, three discharge grooves are provided inside the rotating cylinder 304, and the outer edge of the sliding cylinder 305 is fixedly connected to a limiting column, which is slidably connected to the inside of the discharge groove. The inside of the discharge groove is divided into a stationary section and a discharge section. The arc of the stationary section is connected to the rotation arc of the sliding cylinder 305. The discharge section is set to an arc shape, and the arc extrusion path is the same as the telescopic distance of the sliding cylinder 305.

[0065] In the initial state, the limiting post of the sliding cylinder 305 is in the static section of the discharge groove of the rotating cylinder 304. At this time, the rotation of the rotating cylinder 304 does not drive the limiting post to move, so that the sliding cylinder 305 is in a static state. As the rotating cylinder 304 continues to move, the limiting post enters the discharge section of the discharge groove of the rotating cylinder 304, so that the limiting post is squeezed by the discharge section, and then the limiting post drives the sliding cylinder 305 to move outward from the fixed base 1, squeezes and falls off the iron core bar wound at the end of the winding rod 202, and completes the discharge of the wound iron core bar.

[0066] Then, the rotating cylinder 304 rotates in the opposite direction, and can squeeze the limiting column through the discharge groove, so that the sliding cylinder 305 is retracted into the interior of the fixed base 1 to restore to the initial state.

[0067] See also Figure 6 and Figure 8 As shown, a guide column 3061 is fixedly connected to one side of the limit seat 306, and the outer edge of the guide column 3061 is slidably connected to the inside of the sliding cylinder 305. The guide column 3061 can provide guidance and limitation for the sliding cylinder 305 during the movement of the sliding cylinder 305 to prevent the sliding cylinder 305 from rotating.

[0068] See also Figures 4 to 6 as well as Figure 8 As shown, the winding part 2 includes a winding motor 201, a winding rod 202, a fixed block 203 and an elastic locking piece 204. The winding motor 201 is fixedly connected to the upper part of the fixed base 1, and the winding motor 201 is electrically connected to the control computer of the equipment. One end of the winding rod 202 is fixedly connected to the output end of the winding motor 201, and the winding rod 202 is driven to rotate by the rotation of the winding motor 201. The fixed block 203 is internally slidably connected to the other end of the winding rod 202, and the elastic locking piece 204 is arranged between the winding rod 202 and the fixed block 203. The elastic locking piece 204 always applies pressure to the fixed block 203, so that the fixed block 203 can always squeeze and fix one end of the core bar inside the winding rod 202, so as to provide fixation for the end of the core bar winding to prevent the core bar from detaching from the outer edge of the winding rod 202 during the winding process.

[0069] See also Figures 1 to 7As shown, the extrusion portion 4 includes a guide plate 401, a sliding seat 402, an extrusion seat 403, an elastic extrusion piece 404, an extrusion column 405, and an extrusion disk 406. The guide plate 401 is fixedly connected to the fixed base 1. There are three sliding seats 402, and the three sliding seats 402 are arranged in a ring shape with the winding rod 202 as the axis. The sliding seat 402 is slidably connected to the inside of the guide plate 401, and the outer edge of one end of the extrusion seat 403 is slidably connected to the inside of one side of the sliding seat 402. The elastic extrusion piece 404 is arranged between the sliding seat 402 and the extrusion seat 403. The extrusion column 405 is rotatably arranged at the other end of the extrusion seat 403, and the outer edge of the extrusion column 405 cooperates with the outer edge of the winding rod 202. The interior of the extrusion disk 406 is slidably connected to the other side of the sliding seat 402, and the axis center inside the extrusion disk 406 is fixedly connected to one end of the rotating cylinder 304.

[0070] Since the extrusion disc 406 is fixedly connected to the rotating cylinder 304, the extrusion disc 406 can rotate together with the rotating cylinder 304. In the initial state, the sliding seat 402 is located close to the winding rod 202. At this time, the sliding seat 402 squeezes the elastic extrusion member 404, and applies pressure to the extrusion seat 403 through the elastic extrusion member 404, so that the extrusion seat 403 drives the extrusion column 405 to always apply pressure to the outer edge of the winding rod 202. The three sliding seats 402 can fully squeeze the outer edge of the winding rod 202 in multiple directions. The pressure of the extrusion column 405 can increase the fit between the core bar and the outer edge of the winding rod 202, thereby increasing the tightness of the core bar after winding.

[0071] When the squeezing disc 406 rotates with the rotating cylinder 304, the squeezing disc 406 first squeezes the sliding seat 402, so that the sliding seat 402 moves away from the winding rod 202. At this time, the elastic squeezing member 404 gradually squeezes the sliding seat 402, and the squeezing seat 403 is still squeezed by the elastic squeezing member 404, so that the squeezing column 405 still applies pressure in the direction of the winding rod 202, but the applied pressure is gradually reduced.

[0072] As the squeezing disc 406 continues to rotate, one end of the squeezing seat 403 is limited by the structure of the sliding seat 402 and stops applying pressure to the winding rod 202. Then, the squeezing seat 403 moves away from the winding rod 202 together with the sliding seat 402 until the squeezing column 405 moves out of the extension range of the sliding cylinder 305, thereby preventing the squeezing column 405 from hindering the extension of the sliding cylinder 305.

[0073] As the squeezing disk 406 continues to rotate, the sliding seat 402 is in a stationary state and does not move;

[0074] The reverse rotation of the extrusion disk 406 causes the sliding seat 402 to be in a stationary stage first, and then the sliding seat 402 drives the extrusion seat 403 to move in the direction of the winding rod 202. The sliding seat 402 squeezes the elastic extrusion member 404 to increase the pressure applied by the extrusion seat 403 in the direction of the winding rod 202, thereby increasing the extrusion force of the elastic extrusion member 404 on the extrusion column 405, until the extrusion disk 406 squeezes the sliding seat 402 to restore it to its initial state.

[0075] See also Figure 7 As shown, a guide groove is provided inside the guide plate 401, and there are also three guide grooves. The three guide grooves are arranged in a ring shape with the winding rod 202 as the axis. The inside of the guide groove is slidably connected to the sliding seat 402. The guide groove provides guidance and limitation for the movement of the sliding seat 402 to prevent the sliding seat 402 from moving together with the extrusion plate 406.

[0076] See also Figure 7 As shown, three extrusion grooves are provided inside the extrusion disk 406, and the insides of the three extrusion grooves are slidably connected with the corresponding sliding seats 402. The insides of the extrusion grooves are divided into an extrusion section and a locking section. The extrusion section is arranged in an arc shape, and the extrusion distance of the arc of the extrusion section is the same as the moving distance of the sliding seat 402, and the arc of the locking section is the same as the arc of the rotation path of the extrusion disk 406;

[0077] In the initial state, the sliding seat 402 is located inside the extrusion section inside the extrusion groove. At this time, the sliding seat 402 is located close to the winding rod 202. During the rotation of the extrusion plate 406, the extrusion section of the extrusion plate 406 can squeeze the sliding seat 402, so that the sliding seat 402 moves along the guide groove inside the guide plate 401.

[0078] As the extrusion disk 406 continues to rotate, the sliding seat 402 enters the locking section of the extrusion groove. Since the arc of the locking section is the same as the rotation arc of the extrusion disk 406, the sliding seat 402 is in a stationary locking state.

[0079] It should be noted that the extrusion section of the extrusion groove of the extrusion disc 406 cooperates with the stationary section of the discharge groove of the rotating cylinder 304, so that when the extrusion disc 406 and the rotating cylinder 304 rotate together, the extrusion disc 406 can firstly press the sliding seat 402 through the extrusion section of the extrusion groove to move, and at this time, the sliding cylinder 305 is in the stationary section of the discharge groove of the rotating cylinder 304 and stops;

[0080] The locking section of the extrusion groove of the extrusion plate 406 cooperates with the discharge section of the discharge groove of the rotating cylinder 304. At this time, as the extrusion plate 406 and the rotating cylinder 304 continue to rotate together, the sliding seat 402 is squeezed into the locking section of the extrusion groove by the extrusion section of the extrusion groove of the extrusion plate 406, and the sliding seat 402 is inside the locking section of the extrusion groove. In the subsequent rotation of the extrusion plate 406, the sliding seat 402 is inside the locking section of the extrusion groove and is in a stationary state; the rotation of the rotating cylinder 304 causes the sliding cylinder 305 to enter the discharge section of the discharge groove inside the rotating cylinder 304. In the subsequent rotation of the rotating cylinder 304, the sliding cylinder 305 is squeezed inside the discharge section of the discharge groove, so that the sliding cylinder 305 slides along the inside of the rotating cylinder 304;

[0081] At this point, the linkage between the sliding seat 402 and the sliding cylinder 305 is achieved through the rotation of the extrusion disk 406 and the rotating cylinder 304.

[0082] See also Figures 9 to 17 As shown, the feeding part 5 includes a feeding seat 501, a feeding motor 502, a feeding roller 503, a mounting seat 504, a squeezing roller 505, and an elastic reset member 506. The feeding seat 501 is fixedly connected to the fixed base 1, the feeding motor 502 is fixedly connected to the inside of the feeding seat 501, the feeding motor 502 is electrically connected to the control computer, one end of the feeding roller 503 is fixedly connected to the output end of the feeding motor 502, the feeding roller 503 is driven to rotate by the feeding motor 502, and the mounting seat 504 is slidably arranged inside the feeding seat 501. The mounting seat 504 is vertically corresponding to the feeding roller 503, the squeezing roller 505 is rotatably arranged inside the mounting seat 504, the squeezing roller 505 is vertically corresponding to the feeding roller 503, and the elastic reset member 506 is arranged between the mounting seat 504 and the fixed base 1. The mounting seat 504 is elastically squeezed by the elastic reset member 506, so that the mounting seat 504 drives the squeezing roller 505 to always apply pressure to the feeding roller 503, thereby increasing the friction force of the outer edges of the squeezing roller 505 and the feeding roller 503 on the iron core bar, thereby ensuring the movement and transportation of the iron core bar.

[0083] See also Figures 9 to 17As shown, the docking portion 6 includes a feed plate 601, a sliding plate 602, a conveying seat 603, an elastic pushing member 604, a conveying screw 605, a conveying motor 606, a cutting seat 607 and an elastic lifting member 608. The feed plate 601 is fixedly connected to one end of the feed seat 501, the sliding plate 602 is slidably arranged on the outer edge of the feed plate 601, one end of the sliding plate 602 cooperates with the fixed block 203, the conveying seat 603 is slidably connected to the other end of the sliding plate 602, the elastic pushing member 604 is arranged between the conveying seat 603 and the sliding plate 602, the conveying screw 605 is rotatably arranged inside the feed seat 501, and the inside of the conveying seat 603 is threadedly connected to the outer edge of the conveying screw 605, the conveying motor 606 is fixedly connected to the feed seat 501, the output end of the conveying motor 606 is fixedly connected to one end of the conveying screw 605, and the conveying motor 606 is electrically connected to a control computer.

[0084] The conveying screw 605 is driven to rotate by the rotation of the conveying motor 606, and the conveying seat 603 threadedly connected thereto is driven to move by the rotation of the conveying screw 605, and the docking operation and the cutting operation can be performed by the movement of the conveying seat 603;

[0085] In the initial state, the sliding plate 602 is in a retracted state, and the cutting seat 607 is in a raised state;

[0086] During the docking operation, the conveying screw 605 is driven to rotate by the rotation of the conveying motor 606, so that the conveying seat 603 pushes the sliding plate 602 to extend and move until one end of the sliding plate 602 extends to the outer edge of the winding rod 202. At this time, the sliding plate 602 extends to the maximum distance. During the extension process, the sliding plate 602 can squeeze the fixed block 203 so that the fixed block 203 shrinks into the interior of the winding rod 202 to expose the fixed gap. The interior of the sliding plate 602 cooperates with the fixed gap, and the conveyed iron core bar is guided by the sliding plate 602 and the conveying seat 603, so as to ensure that one end of the iron core bar can be accurately inserted into the fixed gap.

[0087] The conveying screw 605 is driven to rotate in the opposite direction by the rotation of the conveying motor 606, so that the conveying seat 603 drives the sliding plate 602 to retract and move. During the retracting and moving process of the sliding plate 602, the fixed block 203 loses the extrusion of the sliding plate 602, so that the fixed block 203 is extruded by the elastic locking member 204 and extends out, so that one end of the core bar is fixed between the winding rod 202 and the fixed block 203, and then the sliding plate 602 returns to the retracted state;

[0088] The cutting seat 607 is in the lifted state, and when the sliding plate 602 is in the retracted state, the rotation of the conveying motor 606 drives the conveying screw 605 to rotate in the opposite direction, and the conveying seat 603 moves along the conveying screw 605. At this time, the sliding plate 602 is limited by the feeding seat 501 and moves stationarily, so that the conveying seat 603 squeezes the elastic pushing member 604 to move, and the cutting seat 607 is squeezed by the conveying seat 603, so that the cutting seat 607 moves downward to squeeze and cut the iron core strip inside the cutting seat 607, thereby realizing the cutting of the iron core strip;

[0089] The rotation of the conveying motor 606 drives the conveying screw 605 to rotate, and the conveying seat 603 moves to the initial position along the conveying screw 605. Due to the movement of the conveying seat 603, the cutting seat 607 loses the squeezing of the conveying seat 603, and then the cutting seat 607 is squeezed by the elastic lifting member 608 and moves upward to return to the lifted state.

[0090] See also Fig.12 As shown, a cutting blade 6071 is arranged inside the cutting seat 607, and the cutting portion at the lower end of the cutting blade 6071 is arranged to be inclined. The inclined design of the cutting blade 6071 enables the cutting blade 6071 to increase the cutting pressure on the core bar when it moves downward to cut the core bar, thereby ensuring the cutting of the core bar.

[0091] The working principle of the present invention is as follows: one end of the core bar is fixedly conveyed through the inside of the feeding part 5, and then extended to the winding rod 202 through the docking part 6, so that the docking part 6 squeezes the fixed block 203, so that the fixed block 203 shrinks and enters the inside of the winding rod 202, and then the feeding part 5 conveys the core bar, so that the core bar enters the inside of the winding rod 202 along the inside of the docking part 6, and then the docking part 6 resumes contraction, at which time the fixed block 203 loses its extrusion and is squeezed out by the elastic locking piece 204, thereby fixing one end of the core bar between the winding rod 202 and the fixed block 203, and then the winding motor 201 drives the winding rod 202 to rotate, thereby driving the core bar to be wound;

[0092] It should be noted that when the core bar is wound, the core bar is first rotated along the winding rod 202 for one circle, and the core bar is initially fixed and welded by a corresponding welding device on one side;

[0093] While the core bar is being wound, the extrusion part 4 always applies pressure in the direction of the winding rod 202, so that the core bar is more closely attached to the outer edge of the winding rod 202, thereby increasing the tightness of the core bar wound on the winding rod 202 and improving the winding quality of the core bar finished product;

[0094] When the winding of the core strip is about to be finished, the edge is fixed and sealed by the welding device. Then, the output end of the discharge motor 301 drives the discharge screw 302 to rotate. The rotation of the discharge screw 302 drives the rotating gear ring 303, the rotating cylinder 304 and the extrusion plate 406 to rotate together. At this time, the first stage rotation of the rotating cylinder 304 does not squeeze the sliding cylinder 305. At this time, the sliding cylinder 305 is in a stationary state; the rotation of the extrusion plate 406 is in the first stage, and the rotation of the extrusion plate 406 can squeeze the sliding seat 402, so that the sliding seat 402 moves along the inside of the guide plate 401 in the direction away from the winding rod 202, and the sliding seat 402 gradually drives the extrusion seat 403 away from the outer edge of the winding rod 202, so that the finished core strip wound on the outer edge of the winding rod 202 loses the extrusion of the extrusion seat 403;

[0095] The rotation of the extrusion plate 406 is in the first stage, at which the extrusion plate 406 squeezes the sliding seat 402 away from the winding rod 202 at the maximum distance. As the extrusion plate 406 continues to rotate, the extrusion seat 403 does not squeeze the sliding seat 402, so that the sliding seat 402 is in the second stage of stopping; the rotation of the rotating cylinder 304 is in the second stage, and at the same time, the rotation of the rotating cylinder 304 can squeeze the sliding cylinder 305. At this time, the sliding cylinder 305 moves along the winding rod 202 toward the outside of the fixed base 1, so that the sliding cylinder 305 can squeeze the finished iron core bar wound on the outer edge of the winding rod 202, so that the finished product falls off the outer edge of the winding rod 202, and the falling off of the finished iron core bar is completed;

[0096] Then the discharge motor 301 rotates in the opposite direction, so that the sliding cylinder 305 is squeezed by the rotating cylinder 304 and shrinks into the interior of the fixed base 1 to expose the winding rod 202; then the sliding seat 402 is squeezed by the squeezing disk 406 and moves toward the direction of the winding rod 202, so that the squeezing seat 403 drives the squeezing column 405 to contact the winding rod 202, and the squeezing force is always applied to the squeezing seat 403 through the elastic squeezing member 404.
