Description

Technical Field

[0001] The present invention belongs to the technical field of stator winding forming, and specifically relates to a winding sleeve 3D press forming device.

Background Art

[0002] The stator winding 3D forming technology is a revolutionary innovation in the motor manufacturing field. By adopting the wave winding and 3D forming process, not only has the performance of the motor been greatly improved, but it has also promoted the development of the automation and smartness of motor manufacturing. As the technology is being developed, this technology will play a greater role in fields such as new energy vehicles, aerospace, and renewable energy, and will surely provide solid technical support for the research and development of high-efficiency energy-saving devices.

[0003] For a specific stator design (such as windings outside the slots or a stator with a special shape), the winding 3D forming adopts a method of forming with a 2D winding and then performing 3D assembly and processing to realize the 3D forming process of the winding.

[0004] Conventional 3D forming devices directly press-form the linear windings after 2D forming. Since the wire materials in the 2D state are loose and easy to deform, and are prone to causing winding disorder, it is necessary to perform a preliminary winding process on the 2D formed windings and then perform 3D press processing on the wound windings. Therefore, currently, a device that can perform 3D press processing on wound windings is needed.
