Description

Technical Field

[0001] The present application relates to the technical field of transformers, and in particular to a transformer iron core silicon steel sheet stacking platform. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components include primary coil, secondary coil and iron core (magnetic core). The main functions of a transformer include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization (magnetic saturation transformer).

[0003] The existing Chinese patent with announcement number CN217214442U discloses a transformer core silicon steel sheet stacking platform, including a support frame, a lifting device, a core frame and a silicon steel sheet support plate; the core frame is an operating frame for stacking silicon steel sheets to form an iron core, and the silicon steel sheet support plate is used to store silicon steel sheets constituting the iron core. The core frame and the silicon steel sheet support plate are both movably arranged on the support frame through the lifting device, and during the stacking operation, the core frame and the silicon steel sheet support plate are driven by the lifting device to lift and lower at the same time. The utility model provides a transformer core silicon steel sheet stacking platform, which improves the convenience of the core stacking operation, reduces labor intensity, and improves efficiency.

[0004] However, the above-mentioned stacking platform has the following disadvantages: the device enables the core frame and the silicon steel sheet support plate to rise and fall simultaneously by setting a lifting device, but the device cannot limit the position of silicon steel sheets of different sizes during stacking. First, the silicon steel sheets are easily displaced in position due to external force, vibration or other factors during the stacking process. This displacement may accumulate, resulting in a significant reduction in the accuracy of the final stacking structure. Secondly, inaccurate positioning of the silicon steel sheets during the stacking process may cause obstruction of the magnetic flux path or increase in magnetic resistance, thereby reducing the magnetic flux density and efficiency of the transformer. Finally, due to the inaccurate position of the silicon steel sheets, additional adjustments or repairs may be required in subsequent processes, increasing the complexity and cost of manufacturing. At the same time, unqualified stacking structures may also lead to the scrapping of the entire transformer, further increasing the manufacturing cost.

[0005] Therefore, we propose a transformer core silicon steel sheet stacking platform to solve this problem.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
