Description

Technical Field

[0001] This utility model relates to the field of transformer coil molds, specifically a transformer coil support mold. Background Technology

[0002] Transformer coil support molds are an indispensable tool in transformer production. They typically consist of a mold body and other auxiliary structures, usually made of insulating and strong materials such as epoxy board. The main function of this mold is to provide support after the coil is wound, ensuring the shape and dimensional stability of the coil and preventing deformation or damage during subsequent processing or transportation, thus guaranteeing the overall performance and reliability of the transformer. Existing transformer coil support molds generally require inserting support plates one by one into the insertion slots. This process is cumbersome, inefficient, and physically demanding for operators. Furthermore, prolonged use can cause friction between the support plates, leading to wobbling after insertion and subsequent coil deformation and damage during production, affecting production quality and usability. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a transformer coil support mold to solve the technical problems of cumbersome support plate insertion operation, low production efficiency, high labor intensity for workers, and coil deformation caused by easy shaking of the support plate after long-term use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a transformer coil support mold, comprising a main body and an insertion mechanism, wherein the insertion mechanism comprises a movable plate, the movable plate is connected to a ball screw via a screw nut, the ball screw is provided with threads, one end of the ball screw is provided with a handle, one side of the ball screw is provided with a rotating rod, and one side of the rotating rod is provided with a sliding rod;

[0005] A plug-in plate is provided on one side of the movable plate, and a magnetic block is provided at the bottom of the plug-in plate.

[0006] By adopting the above technical solution, the ball screw and screw nut realize the conversion from rotary motion to linear motion, and accurately control the moving distance and position of the movable plate.

[0007] Furthermore, the plug-in plate is provided in a plurality of them, and the plurality of plug-in plates are arranged at equal intervals.

[0008] By adopting the above technical solution, the equally spaced and uniformly arranged plug plates ensure that the coils have the same support conditions and stability during the winding process, thereby guaranteeing the consistency and quality of the coils.

[0009] Furthermore, a top plate is provided on one side of the main body, and the top plate is fixedly connected to the ball screw and the slide bar.

[0010] By adopting the above technical solution, the top plate, as an important component of the mold, provides stable support and fixing points for the ball screw and slide bar.

[0011] Furthermore, the outer surface of the top plate is provided with a sliding groove, which is adapted to the plug-in plate.

[0012] By adopting the above technical solution, the slide provides a clear moving path for the plug-in plate, ensuring the stability and accuracy of the plug-in plate during the moving process.

[0013] Furthermore, a base plate is provided on the other side of the main body, and a magnetic groove is formed on the outer surface of the base plate, which is adapted to the magnetic block.

[0014] By adopting the above technical solution, the magnetic groove enables the plug plate to be firmly connected to the base plate through magnetic attraction, providing stable support and fixation.

[0015] Furthermore, a base is fixedly connected to one side of the base plate, and a rotating rod is provided on one side of the base.

[0016] By adopting the above technical solution, the base enhances the overall structural strength of the mold, making the mold more stable during use and less prone to shaking or deformation.

[0017] Furthermore, the handle is circular in shape, and a rubber layer is provided on the surface of the handle, with friction texture on the surface of the rubber layer.

[0018] By adopting the above technical solution, the circular handle makes it easier for workers to grip during operation, improving the comfort and convenience of operation.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model, by setting up a movable plate and a ball screw, uses a rotating handle to drive the ball screw and screw nut to smoothly convert the rotational motion into linear motion, allowing the plug plate to slide within the mold and achieve positioning and fixation. It precisely controls the moving distance and position of the movable plate, simplifies the operation process of the coil support mold, significantly improves production efficiency, and reduces the labor intensity of workers. Workers no longer need to insert the support plates into the plug slots one by one, thereby reducing tedious operation steps and physical exertion.

[0021] 2. This utility model, by setting up magnetic blocks and magnetic grooves, ensures the stability of the plug-in plate during the coil winding process by the mutual attraction and fixation of the magnetic blocks and magnetic grooves. This effectively prevents coil deformation caused by the shaking of the support plate, thereby improving production quality. The sliding groove provides a clear movement path for the plug-in plate, ensuring the stability and accuracy of the plug-in plate during movement and effectively preventing the plug-in plate from shifting or shaking during movement. This ensures the overall stability of the plug-in plate and the accuracy of coil winding. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] A transformer coil support mold, such as Figures 1-4 As shown, it includes a main body 1 and a plug-in mechanism 8. The plug-in mechanism 8 includes a movable plate 801. The movable plate 801 is connected to a ball screw 804 through a screw nut 807. The ball screw 804 is provided with a thread 806. One end of the ball screw 804 is provided with a handle 805. A rotating rod 7 is provided on one side of the ball screw 804. A sliding rod 803 is provided on one side of the rotating rod 7.

[0030] A plug-in plate 802 is provided on one side of the movable plate 801, and a magnetic block 808 is provided at the bottom of the plug-in plate 802. The ball screw 804 and the screw nut 807 realize the conversion of rotary motion to linear motion, and precisely control the moving distance and position of the movable plate 801. The slide bar 803 provides a stable sliding track for the movable plate 801, ensuring the stability and accuracy of the movable plate 801 during movement.

[0031] See Figure 1 , Figure 3 The plug-in plate 802 is provided in several pieces, and the plug-in plates 802 are evenly arranged at equal intervals. The evenly arranged plug-in plates 802 ensure that the coil has the same support conditions and stability during the winding process, thereby ensuring the consistency and quality of the coil. The plug-in plate 802 ensures the stability and accuracy of the coil during the winding process.

[0032] See Figure 1 , Figure 3 A top plate 5 is provided on one side of the main body 1. The top plate 5 is fixedly connected to the ball screw 804 and the slide bar 803. As an important component of the mold, the top plate 5 provides stable support and fixing points for the ball screw 804 and the slide bar 803. The fixed connection between the top plate 5 and the slide bar 803 provides stable support for the slide bar 803, ensuring the positioning and stability of the plug plate 802 in the mold.

[0033] See Figure 1 The outer surface of the top plate 5 is provided with a sliding groove 6, which is adapted to the plug-in plate 802. The sliding groove 6 provides a clear moving path for the plug-in plate 802, ensuring the stability and accuracy of the plug-in plate 802 during movement. The sliding groove 6 effectively prevents the plug-in plate 802 from shaking and ensures the stability of the plug-in plate 802.

[0034] See Figure 1 On the other side of the main body 1, there is a base plate 2. The outer surface of the base plate 2 is provided with a magnetic groove 4. The magnetic groove 4 is compatible with the magnetic block 808. The magnetic groove 4 enables the plug plate 802 to be firmly connected to the base plate 2 by magnetic attraction, providing stable support and fixation. The base plate 2 provides stable support for the entire mold.

[0035] See Figure 1 A base 3 is fixedly connected to one side of the base plate 2, and a rotating rod 7 is provided on one side of the base 3. The base 3 enhances the overall structural strength of the mold, making the mold more stable during use and less prone to shaking or deformation. The rotating rod 7 allows the entire mold to rotate, which is convenient for protecting the material and the winding of the coil.

[0036] See Figure 1 , Figure 3The handle 805 is arranged in a circular shape, and the surface of the handle 805 is provided with a rubber layer. The surface of the rubber layer is provided with friction texture. The circular handle 805 makes it easier for workers to grip during operation, improving the comfort and convenience of operation. The rubber layer can increase the softness and elasticity of the surface of the handle 805, so that workers will not feel hand fatigue or discomfort during long-term operation.

[0037] The implementation principle of this utility model is as follows: First, after the protective material is wrapped around the surface of the main body 1, the rotation of the rotating rod 7 is stopped. By rotating the handle 805, the movable plate 801 drives the plug plate 802 to slide through the slide groove 6 into the magnetic suction groove 4, and the magnetic block 808 is attracted and fixed to the magnetic suction groove 4. Then, the coil can be wound on the surface of the plug plate 802.

[0038] When demolding is required, the handle 805 can be rotated in reverse so that the movable plate 801 drives the plug plate 802 to leave the magnetic groove 4 and the slide groove 6 in sequence.

[0039] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
