[0029] The following describes an embodiment of the present application in combination with Figures 1 to 5 A winding and pouring dual-purpose tool for transformer winding and a winding manufacturing method are described below.

[0030] Embodiment 1 A winding and pouring dual-purpose tool for transformer winding, comprising a winding part 1, a first air duct mold limiting ring piece 2, a second air duct mold limiting ring piece 3, a pouring outer mold 4 and a base 5; the rotating shaft 13 of the winding part 1 is detachably connected with the winding machine; The first air duct mold limiting ring piece 2 and the second air duct mold limiting ring piece 3 are both sleeved on the outer periphery of the winding part 1, and the first air duct mold limiting ring piece 2 and the second air duct mold limiting ring piece 3 are both radially layered with a plurality of limiting openings 21, and the limiting openings 21 are used for the air duct mold to pass through and install; The base 5 is detachably mounted at the bottom end of the winding part 1, the pouring outer mold 4 is detachably sleeved on the outer periphery of the first air channel mold limiting ring piece 2 and the second air channel mold limiting ring piece 3, and the bottom end of the pouring outer mold 4 abuts against the top surface of the base 5.

[0031] Based on the research and summary of the traditional winding manufacturing method, it is concluded that the essence of winding manufacturing is actually two processes of winding and pouring, so the application provides a winding and pouring dual-purpose tool for transformer winding, which completes the whole process of winding and pouring two processes with one tool, reduces the manual intervention in the process, and greatly improves the winding production efficiency.

[0032] In the preferred embodiment of the winding and pouring dual-purpose tool for transformer winding provided by the application, as shown in the figure, Figures 1 to 3 The dual-purpose tool has two states: (1) When used for the winding process, the pouring outer mold 4 is removed, the rotating shaft 13 of the winding part 1 is connected with the transmission of the winding machine (for example, the top end of the rotating shaft 13 is directly inserted into the rotating port of the winding machine), the first winding layer is wound along the outer surface of the winding part 1 between the first air channel mold limiting ring piece 2 and the second air channel mold limiting ring piece 3 under the drive of the winding machine, then the air channel mold is positioned along the outer periphery of the winding part 1 by using the first layer limiting port 21 of the first air channel mold limiting ring piece 2 and the second air channel mold limiting ring piece 3 (the air channel mold can be inserted by manual or mechanical arm), and the air channel mold (usually a long strip block) is fixed by one-to-one corresponding cooperation of the limiting ports 21 of the first air channel mold limiting ring piece 2 and the second air channel mold limiting ring piece 3, after insulation protection, the next winding layer is wound, and the air channel mold is positioned layer by layer in this way. The traditional way of binding and fixing the air channel mold and the way of inserting the air channel mold after layer-by-layer pouring are replaced, the binding process of the air channel mold by manual and the replacement of the tool are saved, and the efficiency of the winding process is improved.

[0033] (2) When the winding process is completed, the pouring process is used, the rotating shaft 13 of the winding part 1 is detached from the winding machine, the dual-purpose tool is placed vertically through the base 5, and then the pouring outer mold 4 is sleeved. At this time, the pouring outer mold 4 (for example, a pouring cylinder) is sleeved on the outer periphery of the first air channel mold limiting ring piece 2 and the second air channel mold limiting ring piece 3, and the bottom end of the pouring outer mold 4 abuts against the top surface of the base 5, so as to form a pouring groove. The pouring material (the pouring material is usually sticky and will not leak) is poured into the pouring groove through the upper opening of the pouring outer mold 4, the limiting port 21 of the first air channel mold limiting ring piece 2 or the pouring port on the side of the pouring outer mold 4, then the base 5, the pouring outer mold 4 and the air channel mold are detached in turn, and the winding and the winding part 1 are detached, so that an integrally formed winding is directly obtained, and each winding layer and the air channel are poured. The winding has better integration and higher pouring efficiency.

[0034] Further, the winding part 1 comprises a top cover 14, a winding cylinder 11 and a plurality of support plates 12; the support plates 12 are embedded in the cylinder of the winding cylinder 11, and the support plates 12 are uniformly distributed in the cylinder of the winding cylinder 11 from top to bottom, the outer periphery of the support plates 12 abuts against the inner wall of the winding cylinder 11 to form a winding support structure. The central part of the support plate 12 is provided with a shaft mounting hole 121, which is a non-circular opening, for example, the shaft mounting hole 121 is square, and the outer periphery of the shaft 13 is provided with a limiting mounting part, the outer contour of the limiting mounting part is the same as and cooperates with the shape of the shaft mounting hole 121; when the shaft 13 slides through the shaft mounting hole 121, the shaft 13 can drive the support plate 12 to rotate, thereby realizing the transmission between the shaft 13 and the winding part 1; at the same time, the top and bottom of the shaft 13 pass through the top cover 14 and the base 5 respectively, and the subsequent winding machine can be freely connected with the top or bottom end of the shaft 13; in addition, the top cover 14 and the base 5 are detachably installed on the top and bottom of the shaft 13 respectively, and the top cover 14 and the base 5 abut against the top end and the bottom end of the winding cylinder 11 respectively, and the winding cylinder 11 is clamped and fixed by the cooperation of the top cover 14 and the base 5.

[0035] Further, the side of the top cover 14 extends outwardly and is provided with at least two mounting brackets 141; the mounting brackets 141 are uniformly distributed along the side of the top cover 14, and the mounting brackets 141 are provided with mounting through slots 142.

[0036] In this embodiment, the installation mode of the pouring outer mold 4 is sleeved on the outer periphery of the first air duct mold limiting ring piece 2 and the second air duct mold limiting ring piece 3, so a supporting piece is needed to limit or fix it to ensure that it will not be displaced during pouring, and it is preferred that at least two mounting brackets 141 are outwardly extended on the side of the top cover 14, and mounting through slots 142 are arranged on the mounting brackets 141, one end of the supporting piece is connected with the mounting through slots 142, and the other end of the supporting piece is connected with the top end of the pouring outer mold 4, for example, the supporting piece is a connecting rod, one end of the connecting rod passes through the mounting through slot 142 and is adjusted at a suitable position in the mounting through slot 142, the two nuts on the connecting rod are respectively tightened and fixed on the upper and lower sides of the mounting bracket 141, and the other end of the connecting rod is provided with an opening, and the top end of the pouring outer mold 4 is inserted into the opening, so that the position of the pouring outer mold 4 is fixed by the connecting rod.

[0037] Further, the bottom surface of the base 5 is provided with a supporting pad 51, and the height of the supporting pad 51 is higher than the height of the shaft 13 protruding from the base 5.

[0038] In this embodiment, the shaft 13 passes through the base 5 in order to be connected with the winding machine; therefore, the main function of the supporting pad 51 is to enable the bottom surface of the dual-purpose tool to be stably placed on a plane when the dual-purpose tool is used in the pouring process, and therefore the height of the supporting pad 51 needs to be higher than the height of the shaft 13 protruding from the base 5, and the structure of the supporting pad 51 is not limited here and can be like Figure 2As shown, it is composed of at least two legs, and can also be a lifting support.

[0039] Further, the first air duct mold limiting ring piece 2 is sleeved at the bottom end of the winding part 1, and is provided with a bottom surface for abutting with the top surface of the base 5; the second air duct mold limiting ring piece 3 is sleeved above the first air duct mold limiting ring piece 2.

[0040] In this embodiment, the top end of the rotating shaft 13 is installed at the back of the winding machine, and the base 5 limits the air duct mold from continuing to extend outwardly, so the first air duct mold limiting ring piece 2 needs to be sleeved at the bottom end of the winding part 1 to cooperate with the base 5 to limit the bottom end of the air duct mold, which is more conducive to the vertical placement of the dual-purpose tool in the pouring process, and the first air duct mold limiting ring piece 2 is not easy to shift (limited by the top surface of the base 5); and the second air duct mold limiting ring piece 3 is freely sleeved above the first air duct mold limiting ring piece 2, which cooperates with the first air duct mold limiting ring piece 2 to erect the air duct mold.

[0041] Further, the first air duct mold limiting ring piece 2 is not provided with a break, and the second air duct mold limiting ring piece 3 is provided with a break.

[0042] In this embodiment, the first air duct mold limiting ring piece 2 sleeved at the bottom end of the winding part 1 does not need to be sleeved along the winding part 1, so it does not need to be provided with a break; and the second air duct mold limiting ring piece 3 needs to be sleeved and adjusted in position, so it needs to be provided with a break to facilitate the sliding of the second air duct mold limiting ring piece 3.

[0043] Further, the support plate 12 is provided with a grabbing structure 122 on the periphery of the rotating shaft mounting port 121.

[0044] In this embodiment, the support plate 12 needs to be installed in the cylinder of the winding cylinder 11 in sequence, and the grabbing structure 122 facilitates the machine to grab and deeply embed the support plate 12 in the cylinder of the winding cylinder 11.

[0045] In addition, the grabbing structure 122 is preferably a grabbing port that is opened through, and at least two grabbing structures 122 are provided, so that the gripper of the machine can pass through the grabbing ports of multiple support plates 12 at one time, and the support plate 12 can be grabbed through the at least two grabbing ports, preventing the support plate 12 from shifting during embedding, so that multiple support plates 12 can be embedded in the cylinder of the winding cylinder 11 at one time.

[0046] Further, the support plate 12 is provided with a mounting hole 123 on the periphery of the rotating shaft mounting port 121.

[0047] In this embodiment, the reserved mounting hole 123 can be used for subsequent installation (or limiting) of the top cover 14, the base 5 or other accessories of the winding machine. For example, the mounting hole 123 can be matched with a screw to fix the accessory to the top end and the bottom end of the winding cylinder 11. For another example, the top surface of the top cover 13 and the top surface of the base 5 are provided with a limiting column, and the limiting column passes through the mounting hole 123 to limit the support plate 12.

[0048] Further, the winding cylinder 11 comprises a flexible metal plate 111 and a clamp 112. The left and right ends of the flexible metal plate 111 are curled to form a cylindrical shape, and the clamp 112 clamps the left and right ends of the flexible metal plate 111 on the inner side of the flexible metal plate 111.

[0049] In this embodiment, the winding cylinder 11 is preferably formed by curling the left and right ends of the flexible metal plate 111. The flexibility of the flexible metal plate 111 can adapt the inner wall of the winding cylinder 11 to the outer peripheral contour of the support plate 12, so that the inner wall of the winding cylinder 11 and the outer periphery of the support plate 12 are in close contact, and the size of the winding space can be adjusted (by replacing the support plate 12 and changing the clamping position). In addition, the clamp 112 clamps the left and right ends of the flexible metal plate 111 on the inner side of the cylindrical flexible metal plate 111, which can avoid the influence of the protruding clamping part on the winding.

[0050] It should be noted that the structure of the clamp 112 is not limited here and can be as shown in Figure 4 The three long blocks are longitudinally placed on the left side of the left end of the flexible metal plate 111, between the left end and the right end of the flexible metal plate 111, and on the right side of the right end of the flexible metal plate 111, clamping the left and right ends of the flexible metal plate 111. The long blocks are provided with a plurality of threaded holes in the length direction, and then the threaded holes of the three long blocks are connected and fixed by screws.

[0051] Similarly, the structure of the pouring outer mold 4 is similar to that of the winding cylinder 11, and the difference is that the pouring outer mold 4 preferably clamps the left and right ends of the flexible metal plate on the outer side.
