Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of transformer core forming equipment, specifically a transformer core forming device. Background Technology
[0002] The transformer core is a crucial component of a transformer, its primary function being to provide a magnetic flux path for the conversion of electromagnetic energy. The core is typically made of materials with good magnetic permeability to ensure efficient energy transmission. The design and material selection of the core significantly impact the transformer's performance, efficiency, and size.
[0003] The main function of a transformer core is
[0004] Providing a magnetic flux path: The working principle of a transformer is based on electromagnetic induction. The iron core provides a low-impedance magnetic flux path, which enables the alternating magnetic field generated in the primary winding to be effectively coupled to the secondary winding, thus completing the energy conversion.
[0005] Improving transformer efficiency: The high permeability of the iron core (i.e., its ability to conduct magnetic flux) allows the transformer to transfer more energy in a smaller volume, reducing energy loss.
[0006] Reduced magnetic leakage: The structure and materials of the iron core can reduce magnetic leakage, ensuring that most of the magnetic field is effectively transmitted, thereby improving the transformer's operating efficiency.
[0007] In the manufacturing process, transformer cores are usually made by cold rolling or hot rolling. Cold rolling is often carried out using a cold rolling mill. However, during the demolding process, the core is easily stuck in the mold of the cold rolling mill, which makes demolding difficult. There is room for improvement. Utility Model Content

[0013] As a further embodiment of this utility model: a core forming device for transformer production, wherein the size of the connecting pipe adapter hole is larger than that of the lubrication hole, and the connecting pipe adapter hole and the lubrication hole are stepped hole structures.
[0014] As a further embodiment of this utility model: a core forming device for transformer production, further comprising a guide rod, wherein the cold rolling head is movably connected to the guide rod.
