Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to a mechanical tension mechanism for winding machines. Background Technology

[0002] In the production of electromagnetic components such as motors, transformers, and inductors, winding is one of the core processes. The stability of the winding tension directly determines the winding quality, performance, and service life of the coil. Excessive tension can easily lead to wire stretching and deformation, insulation damage, and even wire breakage, reducing the coil's current-carrying capacity and insulation reliability. Insufficient tension, on the other hand, can cause loose winding, uneven interlayer gaps, and problems such as fluctuating electrical performance and abnormal temperature rise. Existing winding tension mechanisms suffer from large tension fluctuations, low guiding accuracy, easy wire skipping, and inconvenient adjustment, failing to meet the requirements for stable and high-precision winding.

[0003] Existing winding tensioners mainly suffer from the following defects: (1) Lagging tension response: During the winding process, fluctuations in the wire release speed of the coil and the rotation speed of the winding shaft can cause sudden tension changes. Traditional structures cannot compensate for the tension, which can easily lead to problems such as wire breakage and wire skipping. (2) Poor structural versatility: For different wire diameters and different winding processes, it is necessary to replace springs, counterweights and other components, which is complicated to adjust and cannot meet the flexible production needs of multiple varieties and small batches. (3) Weak anti-interference ability: Vibration, wire displacement and coil inertia during the winding process will directly affect the tension stability. Traditional structures have no buffer and adaptive compensation design, resulting in large tension fluctuations. (4) The wire release speed of the Alpha coil during the wire pulling and storage process is higher than that during the winding process, which requires switching between different tension levels.

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a winding tension mechanism that is simple in structure, stable in tension, reliable in guidance, and easy to adjust, as well as a winding tension control mechanism with adaptive compensation capability, to meet the needs of modern precision winding processes.

[0014] The advantages and positive effects of the mechanical tension mechanism for a winding machine described in this utility model are: 1. This utility model achieves real-time response to changes in winding tension through the spring between the connecting rod and the connecting swing arm in the tensioner. When the tension changes abruptly, the spring rapidly extends, absorbing the instantaneous tension fluctuation; the angled swing arm in the anti-tension compensation component rotates around the bearing under the action of the tension spring, applying a reverse compensation force to the wire, significantly improving the tension stability during the winding process. When rapid wire pulling and storage are required, the cylinder pushes up to open the tensioner's damping brake, releasing the tension, thereby reducing resistance during the wire unwinding process.

[0015] 2. This utility model adopts a modular design. Each functional component (magnetic pig tail assembly, tensioner, and anti-tension compensation assembly) is mounted on the Y-axis adjusting rod via adjusting blocks and secured with bolts, enabling rapid position adjustment along the Y-axis. The tensioner is height-adjustable via a tension swing arm adjusting rod and a sleeve structure, eliminating the need to replace the entire assembly.
