Description

Technical Field

[0001] This application belongs to the field of automated production of amorphous three-dimensional coiled iron cores, and specifically proposes an amorphous triangular three-dimensional coiled iron core winding machine. Background Technology

[0002] For the transformer industry, the production and manufacturing of amorphous strip coiled cores plays a crucial role. Currently, in the production and manufacturing process of amorphous core transformers, the assembled and glued amorphous triangular three-dimensional coiled core needs to undergo foil winding or wire winding processes on three core columns. Therefore, the core needs to be clamped and able to rotate to switch between the individual core columns.

[0003] Existing three-dimensional coiled iron core winding equipment relies primarily on pads and pressure plates on a pair of concentrically mounted rotating shafts to clamp and fix the iron core. However, before winding, most iron cores exhibit significant dimensional deviations along the axial direction due to prolonged storage or errors in the winding and assembly processes. This leads to noticeable eccentricity during core positioning, which is difficult to adjust. Further improvements are needed in core positioning accuracy and winding efficiency.

[0004] In view of the above, this patent application is hereby filed. Summary of the Invention
