Description

Technical Field

[0001] The present invention belongs to the technical field of stator wave winding forming, and in particular, relates to a 3D stamping forming device for a wave winding sleeve. Background Art

[0002] Stator wave winding 3D molding technology is a revolutionary innovation in the field of motor manufacturing. By adopting wave winding and 3D molding technology, it not only greatly improves the performance of the motor, but also promotes the development of motor manufacturing towards automation and intelligence. With the continuous improvement of technology, this technology will surely play a greater role in new energy vehicles, aerospace and renewable energy, and provide solid technical support for the research and development of high-efficiency and energy-saving equipment.

[0003] For specific stator designs (such as slot-out windings or stators with special shapes), the wave-wound wire 3D forming adopts the method of first forming the 2D wave-wound wire and then performing 3D assembly or processing to achieve the 3D forming of the wave-wound wire.

[0004] Since traditional 3D forming equipment directly stamps out the linear wave winding wire that has been 2D formed, and since the wire in the 2D state is relatively loose and easy to deform, it is easy to cause winding disorder. Therefore, it is necessary to pre-roll the 2D formed wave winding wire and then perform 3D stamping on the rolled wave winding wire. Therefore, there is a need for a device that can perform 3D stamping on rolled wave winding wire. Summary of the invention

The three upper stamping assemblies are respectively located in the positive left direction, positive right direction and positive top direction of the support assembly, and the directions are perpendicular to each other, forming three orthogonal directions, and the angles are all 90 degrees;

[0012] Each of the upper stamping components includes an upper assembly seat and an upper stamping cylinder installed at the upper assembly seat, the upper assembly seat is fixed to the assembly surface of the mounting plate located on the rear side, the output end of the upper stamping cylinder is installed with an upper connecting seat, the upper connecting seat is slidably installed on the assembly surface of the mounting plate, and the upper stamping die adapted to the upper bottom die is installed at one end of the upper connecting seat close to the support assembly.

[0013] Furthermore, the lower end stamping assembly includes two lower end assembly seats which are symmetrically distributed with the Y-axis line of the assembly surface of the mounting plate as the axis and are fixed at an angle of 45 degrees to the Y-axis line.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The rolled 2D wave winding wire can be punched to achieve the purpose of punching and forming the upper, lower and side ends of the 3D pre-formed wave winding wire.
