Description
Technical Field
[0001] This utility model relates to the field of transformer winding technology, and in particular to a winding device for transformer production. Background Technology
[0002] In the modern power industry, transformers are the core equipment for power transmission and distribution. Their performance and quality are directly related to the stable operation of the power system and the energy utilization efficiency. In the transformer manufacturing process, the winding process is one of the key links, which directly affects the electrical performance, heat dissipation effect and service life of the transformer. Therefore, developing efficient and precise winding devices for transformer production is of great significance for improving the transformer manufacturing level, reducing costs and enhancing market competitiveness. However, the winding devices for transformer production that are widely used in the market at present still have some shortcomings in structural design. These shortcomings not only affect production efficiency, but may also have potential impacts on the performance of the transformer.
[0003] In the existing winding process, the winding accuracy is difficult to guarantee due to wear of mechanical parts, accumulation of errors in the transmission system, and inaccuracy of the control system. At the same time, the tension of the coil is difficult to control during the winding process, resulting in coil slack and affecting the electrical performance of the transformer. Furthermore, many traditional winding devices still rely on manual operation, with a low degree of automation. This not only increases labor costs but also limits the improvement of production efficiency. In addition, the uncertainty brought about by manual operation may also lead to unstable product quality.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. The winding device for transformer production has a fixed frame on the top of the upright plate. The fixed frame has a sliding groove inside, and an adjustable limiting plate is installed inside the sliding groove. A second drive motor drives a second lead screw to move a second electric telescopic rod back and forth inside the sliding groove. A high-precision transmission structure is adopted. By extending and retracting the limiting plate of the second electric telescopic rod, errors in the winding process are adjusted, effectively preventing the coil from shifting or breaking during winding, ensuring the integrity and stability of the coil.

By precisely controlling the motor's speed and direction, precise control of the coil can be achieved. This method not only improves pay-off accuracy but also greatly increases production efficiency. In addition, the motor drive has the advantages of simple operation and convenient maintenance, which helps to reduce maintenance costs. At the same time, in conjunction with the first drive motor, which drives the transformer winding, precise control of the coil tension can be achieved, which not only improves the coil tension but also ensures the coil's stability and electrical performance.
[0017] 3. The trough is equipped with an easily replaceable conveyor and an adjustable limit plate to achieve automated operation and precise limit control of the winding process, reducing manual intervention. At the same time, in conjunction with the tension adjustment mechanism, it not only improves the wire feeding accuracy but also greatly increases production efficiency. Furthermore, the transformer after winding is transported by the conveyor, further improving the level of automation. Attached Figure Description
