Description

Technical Field

[0001] The utility model relates to the field of transformer coil winding, in particular to an adjustable winding die. Background Art

[0002] The coil, the heart of a transformer, plays a crucial role in carrying current and changing voltage. During transformer design, to meet manufacturing cost and performance requirements, coil parameters such as inner and outer diameters, height, number of turns, and wire cross-sections are often different for different capacities. Winding dies are essential to ensure that coil dimensions meet design requirements. During transformer coil production, dies play two key roles: Transformer coils are wound with materials such as magnet wire or copper foil, insulating paper, tape, and oil channels. To wind these materials and create a coil that meets performance requirements, dies are essential as the initial framework and support for coil winding. Furthermore, during the winding process, a motor or other power source rotates the die, enabling coil winding. Due to varying performance requirements, coils of different capacities and products often have varying inner and outer diameters and heights. To ensure the coils meet required inner and outer diameters, dies with the correct dimensions are essential.

[0003] The following problems exist in the use of winding molds: To meet the production needs of transformer coils, the outer diameter of transformer coil molds is currently a specific value. Once manufactured, it cannot be adjusted and cannot be used to produce coils with other inner diameters. For molds with fixed sizes, the cost of a set is around several thousand yuan. In addition, due to the large output of transformers, multiple winding machines running simultaneously require a corresponding number of molds. Therefore, it is often necessary to purchase dozens of sets of winding molds of the same specification. For transformers of different capacity models, winding molds of different specifications are required, which will result in a large number of winding molds. Not only does it cost a lot of financial and material resources to manufacture the molds, but it also requires a large amount of mold storage and management costs. For product designers, if they need to consider whether there is a suitable mold before production every time they design a new product, they will have to spend time designing the mold, which will take up the overall design time of the product and reduce design efficiency. Utility Model Content

[0004] The existing technology has the problem that the mold size is fixed and lacks flexibility in use. An adjustable winding mold is provided.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable winding mold, comprising a mold body, wherein a mounting seat and an adjustment mechanism are arranged inside the mold body, and the adjustment mechanism comprises a driving mechanism and a push rod, wherein the driving mechanism is connected to the mounting seat, one end of the push rod is connected to the driving mechanism, and the other end of the push rod cooperates with the side wall of the mold body.

[0006] Preferably, the shape of the mold body is elliptical.

[0007] Preferably, the mold body is an integrated structure.

[0008] Preferably, the adjusting mechanism is provided in plurality, and the plurality of adjusting mechanisms are arranged along the outer ring of the mounting seat.

[0009] Preferably, the telescopic track includes a push rod and a connector, the push rod is connected to the drive motor, and the connector cooperates with the mold body.

[0010] Preferably, the driving mechanism is a DC motor, an AC motor or a stepping motor.

[0011] Compared with existing technologies, this new invention offers the following advantages: Through a built-in adjustment mechanism, the mold body can be precisely adjusted to suit different coil winding methods (such as foil winding) and required dimensions. This greatly enhances the mold's adaptability, allowing a single mold to accommodate a variety of winding processes and specifications, significantly reducing production costs and the complexity of mold replacement.

[0012] Because the mold can be quickly adjusted to accommodate coils of varying sizes, production preparation time and downtime due to mold changes are reduced, thereby improving production efficiency. Furthermore, precise size adjustment helps ensure the accuracy and consistency of the wound coils, improving product quality.

[0013] The mold body adopts an oval design, which not only meets the requirements of certain winding processes but also reduces stress concentration. The one-piece mold body structure design enhances the overall structural stability and durability, reducing repair costs caused by loose or damaged components.

[0014] Multiple adjustment mechanisms are arranged along the outer ring of the mounting base, enabling more uniform and stable dimensional changes during the mold adjustment process, further improving the accuracy and reliability of the adjustment. This multi-point adjustment method helps ensure stable operation of the mold under complex working conditions.

[0015] Using DC, AC, or stepper motors as drive sources provides users with a variety of options to adapt to different working environments and performance requirements. Stepper motors are particularly suitable for applications that require precise control of position or speed, ensuring accuracy and controllability of the adjustment process.
