In this regard, a comparative model of copper tube electromagnetic flanging based on both conventional coils and triangular magnetic field shapers was developed using COMSOL software. The effects of structural parameters of the drive coils and magnetic field shapers on the electromagnetic force distribution and forming performance of tube fittings were systematically investigated. Under identical initial energy storage conditions, the flanging performance of the proposed method was compared with that of conventional flanging techniques. The results indicate that, for a given discharge voltage, optimal flanging can be achieved by appropriately selecting the number of coil turns and layers, as well as the height and width of the magnetic field shaper. Furthermore, compared to traditional methods, the triangular field shaper significantly enhances the axial electromagnetic force, improves the uniformity of the magnetic field distribution, and enables the copper tube to achieve a flanging angle of up to 90°. In contrast, conventional electromagnetic flanging methods, under the same voltage, can only reach a maximum flanging angle of approximately 48.5°. This new copper tube electromagnetic flanging approach effectively addresses the limitations of traditional methods and offers promising insights for the industrial application of electromagnetic forming technologies. electromagnetic flanging axial electromagnetic force magnetic field shaper flanging Angle Full Text Cite Share Download PDF Status: Under Revision Version 1 posted Editorial decision: Major Revisions Needed 18 Mar, 2026 Reviewers agreed at journal 13 Sep, 2025 Reviewers invited by journal 07 Sep, 2025 Editor assigned by journal 28 Jul, 2025 First submitted to journal 26 Jul, 2025 You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
