DETAILED DESCRIPTION

[0027] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0028] Please refer to Figures 1 to 5 According to the coil winding mold provided by the embodiment of the present application, the support shaft 1 is arranged on the installation reference, and the support shaft 1 extends along the vertical direction; the plurality of first positioning plates 2 are arranged in a circumferential direction of the support shaft 1, and the plurality of first positioning plates 2 form a winding area for positioning the coil; each first positioning plate 2 is movably arranged relative to the support shaft 1, so as to expand in a direction away from the support shaft 1 or contract in a direction close to the support shaft 1 through each first positioning plate 2 synchronously, and the size of the winding area is adjusted.

[0029] It can be seen that the coil winding mold provided by the utility model includes a support shaft 1 and a plurality of first positioning plates 2, wherein the support shaft 1 is arranged on a mounting reference, the support shaft 1 extends in the vertical direction, and the support shaft 1 is arranged protruding from the mounting reference; the plurality of first positioning plates 2 are arranged in a circumferential direction of the support shaft 1; the plurality of first positioning plates 2 form a winding area for positioning a coil; each first positioning plate 2 is movably arranged relative to the support shaft 1, so that each first positioning plate 2 can expand towards a direction away from the support shaft 1 or contract towards a direction close to the support shaft 1, thereby adjusting the position of each first positioning plate 2 relative to the support shaft 1, so as to adjust the size of the winding area. Therefore, by movably arranging each first positioning plate 2 relative to the support shaft 1, the size of the winding area can be flexibly adjusted as needed. Furthermore, the coil winding mold can adapt to coils of various sizes and types, thereby significantly improving the versatility and flexibility of the device. Compared with the traditional fixed structure, this design enables the operator to complete the adjustment of the winding area in a short time, reducing the time and complexity of replacing the mold or reconfiguring. At the same time, the synchronous movement design of each first positioning plate 2 ensures uniform expansion or contraction of the winding area, avoiding unevenness or asymmetry caused by manual adjustment, thereby significantly improving the precision and consistency of coil winding. Moreover, through precise adjustment, the available space is maximized while meeting the winding requirements, and the waste rate caused by size mismatch is reduced, thereby reducing production costs and improving product quality. In addition, the design of the support shaft 1 ensures the stability of the entire mold, reducing the vibration or deviation that may occur during winding, further improving winding quality and efficiency. The coil winding mold of the utility model has a simple structure and is easy to operate. The efficient adjustment mechanism and stable structure design make the winding process smoother, reducing adjustment time and downtime, significantly improving overall production efficiency, and effectively solving the technical problem that most existing winding molds are fixed structures and the winding diameter cannot be adjusted.

[0030] Specifically, when the winding area needs to be expanded, each first positioning plate 2 moves outward synchronously, so that the winding area increases; conversely, when the winding area needs to be reduced, each first positioning plate 2 moves inward synchronously, so that the winding area decreases. This synchronous movement ensures uniform expansion or contraction of the winding area, improving the precision and efficiency of coil winding.

[0031] Specifically, as Figure 1As shown, the coil winding mold also includes: a movable component 3 and multiple transmission rods 4. The movable component 3 is movably sleeved on the support shaft 1 along its extension direction, and the position of the movable component 3 and the support shaft 1 is adjustable. Multiple transmission rods 4 are arranged around the movable component 3 in the circumferential direction, and each transmission rod 4 corresponds to a multiple first positioning plate 2. The two ends of each transmission rod 4 are hinged to the movable component 3 and the corresponding first positioning plate 2, respectively. When the movable component 3 moves along the extension direction of the support shaft 1, it drives each first positioning plate 2 to expand or contract via the transmission rods 4, thereby adjusting the size of the winding area. With this structural arrangement, the movable component 3 is movably sleeved on the support shaft 1 along its extension direction, and the position of the movable component 3 and the support shaft 1 is adjustable, ensuring that the size of the mold can be flexibly adjusted as needed during the winding process to adapt to different winding specifications. Multiple transmission rods 4 are arranged circumferentially around the movable component 3 and correspond one-to-one with multiple first positioning plates 2. This configuration allows for efficient synchronous expansion or contraction of each first positioning plate 2 via the transmission rod 4 when the moving part 3 moves, ensuring precise adjustment of the winding area. Both ends of each transmission rod 4 are hinged to the moving part 3 and the corresponding first positioning plate 2. This hinged structure provides greater freedom of movement, making the movements of each positioning plate more stable and uniform during expansion and contraction.

[0032] Furthermore, there are multiple moving parts 3, which are spaced apart along the extension direction of the support shaft 1; multiple transmission rods 4 form a group of transmission components, and each moving part 3 is provided with at least two groups of transmission components, which are spaced apart along the extension direction of the support shaft 1.

With such a structural arrangement, by adjusting the position of the support seat 7, the mold can adapt to the winding requirements of coils of different heights, without the need to replace the mold for each coil height, greatly improving the versatility of the mold. This adjustable design reduces the time and cost of replacing the mold due to changes in coil specifications, improving production efficiency.

[0059] The working process of the coil winding mold is as follows:

[0060] When the coil of the transformer needs to be wound, the worker sends the size of the coil to the controller, so that the controller starts to drive the speed reducer to start rotating, thereby controlling the rotation speed and rotation number of the speed reducer. When the speed reducer rotates, the drive screw rotates to drive the moving part 3 to rise along the extension direction of the support shaft 1, so that the end of each transmission rod 4 close to the moving part 3 rotates relative to the moving part 3, and the end of each transmission rod 4 away from the moving part 3 rotates relative to the corresponding first positioning plate 2, thereby driving each first positioning plate 2 to expand away from the screw. Finally, the size of the winding area meets the design requirements.

[0061] If the expansion of each first positioning plate 2 towards the direction away from the screw can reach the size of the coil manufacturing size, each support base 7 is installed on the first positioning plate 2 according to the height size of the coil.

[0062] If each first positioning plate 2 is expanded to the maximum distance, and the size of the winding area does not reach the requirement of the coil manufacturing size, at this time, at least one second positioning plate 61 can be stacked on each first positioning plate 2 according to the remaining size.

[0063] When the second positioning plate 61 of the first set of second positioning assemblies 6 is correspondingly installed on the first positioning plate 2, the mounting block 612 (i.e. T-shaped block) is installed in the first mounting groove 21, so that the second positioning plate 61 is relatively fixedly connected with the first positioning plate 2. When the second positioning plate of the second set of second positioning assemblies 6 is installed on the corresponding second positioning plate 61 of the first set of second positioning assemblies 6, the mounting block 612 (i.e. T-shaped block) is installed in the second mounting groove 610, and the like.

[0064] When the size of the winding area reaches the requirement of the coil manufacturing size, each support base 7 is installed on the second positioning plate 61 according to the height size of the coil.
