Description

Technical Field

[0001] This invention belongs to the field of stator wave winding forming technology, specifically, it relates to 3D stamping forming equipment for wave winding sleeves. Background Technology

[0002] Stator wave winding 3D forming technology is a revolutionary innovation in the field of motor manufacturing. By employing wave winding and 3D forming processes, it not only significantly improves motor performance but also drives motor manufacturing towards automation and intelligence. With continuous technological advancements, this technology will undoubtedly play a greater role in fields such as new energy vehicles, aerospace, and renewable energy, providing solid technical support for the research and development of highly efficient and energy-saving equipment.

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

[0004] Traditional 3D forming equipment directly stamps and forms 2D-formed linear corrugated wires. Since the 2D wires are relatively loose and easily deformed, they are prone to winding misalignment. Therefore, it is necessary to pre-roll the 2D-formed corrugated wires before performing 3D stamping. Thus, there is a need for equipment that can perform 3D stamping on rolled corrugated wires. Summary of the Invention

[0005] To address the above deficiencies, the present invention provides a 3D stamping forming equipment for corrugated wire sleeves, including a worktable, a top plate mounted on the top of the worktable, two symmetrically arranged mounting plates mounted on the working surface of the top plate, and a support assembly for winding the corrugated wire sleeves between the two mounting plates.

[0006] The support assembly is provided with several upper stamping assemblies for stamping the upper end of the wave-wound sleeve.

[0007] Both sides of the top of the support assembly are provided with lower end stamping assemblies for stamping the lower end of the wave winding sleeve.

[0008] Both sides of the bottom of the support component are provided with side end stamping components for stamping the side ends of the wave-wound sleeve.

[0009] Furthermore, the support assembly includes a support base fixedly installed on the working surface of the top plate, an inner mold base is installed at the top of the support base, a wire-bearing cylinder is fixedly installed at the top and bottom of the middle section of the inner mold base, a wire-bearing cylinder is fixedly connected to the output end of the wire-bearing cylinder, and the wire-bearing block supports the corrugated wire sleeve through a U-shaped groove;

[0010] Furthermore, the outer ring of the inner mold base is respectively equipped with an upper bottom mold, a lower bottom mold, and a side bottom mold adapted to the upper stamping assembly, the lower stamping assembly, and the side stamping assembly.

[0011] Furthermore, there are three upper stamping components, which are respectively installed between two mounting plates. The three upper stamping components are located to the left, right and above the support component, respectively, and their directions are perpendicular to each other. The three form three orthogonal directions with an included angle of 90 degrees.

[0012] Each of the upper stamping components includes an upper mounting base and an upper stamping cylinder mounted on the upper mounting base. The upper mounting base is fixed to the mounting surface of the mounting plate located on the rear side. An upper connecting seat is mounted on the output end of the upper stamping cylinder. The upper connecting seat is slidably mounted on the mounting surface of the mounting plate. An upper stamping die adapted to the upper bottom die is mounted on the end of the upper connecting seat near the support component.

[0013] Furthermore, the lower stamping assembly includes two lower mounting seats that are symmetrically distributed about the Y-axis of the mounting plate assembly surface and are fixed at an angle of 45 degrees to the Y-axis. A lower stamping cylinder is mounted on the top of the lower mounting seat, and a lower connecting seat is fixed to the output end of the lower stamping cylinder. The lower connecting seat is slidably connected to the mounting surface of the mounting plate, and a lower stamping die adapted to the lower bottom die is mounted on the end of the lower connecting seat near the support assembly.

[0014] Furthermore, the side-end stamping assembly includes two side-end mounting plates that are respectively set at an angle of 45 degrees to the upper-end stamping assembly adjacent to the same side. The side-end mounting plates are mounted on the mounting surface of the mounting plate. Each side-end mounting plate is equipped with a side-end stamping cylinder. The output end of the side-end stamping cylinder is equipped with a side-end stamping die adapted to the side-end bottom die.

[0015] Furthermore, both mounting plates have symmetrical slots in the middle for loading and unloading the wave-wound sleeve.

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

[0017] It can stamp rolled 2D corrugated wire to achieve the purpose of stamping the upper end, lower end and side end of 3D preformed corrugated wire. Compared with the traditional method of directly stamping linear 2D corrugated wire into 3D corrugated wire, it reduces the risk of direct stamping, makes the formed 3D corrugated wire more stable, and reduces the occurrence of deformation.

The middle of the two mounting plates 3 is symmetrically provided with slots for loading and unloading corrugated wire sleeves. The size of the slots can be adjusted according to the actual situation to facilitate the workers to pick up and put down the corrugated wire. A support component 4 for winding the corrugated wire sleeve is provided between the two mounting plates 3.

[0027] In detail, the support component 4 includes a support base 401 fixedly installed on the working surface of the top plate 2. An inner mold base 402 is installed on the top of the support base 401. A wire-bearing cylinder 403 is fixedly installed on the top and bottom of the middle section of the inner mold base 402. A wire support block 404 is fixedly connected to the output end of the wire-bearing cylinder 403. The wire support block 404 supports the corrugated wire sleeve (i.e., the coiled corrugated wire, which will not be described in detail below) through a U-shaped groove to avoid displacement during the stamping process and ensure the stamping effect.

[0028] Furthermore, the outer ring of the inner mold base 402 is equipped with an upper bottom mold 8, a lower bottom mold 9, and a side bottom mold 10 that are adapted to the upper stamping assembly 5, the lower stamping assembly 6, and the side stamping assembly 7, respectively. After they are matched one by one, it is convenient to stamp each bend of the wave winding sleeve in the future.

[0029] The support component 4 is provided with several upper stamping components 5 for stamping the upper end of the wave winding sleeve.

[0030] In detail, there are three upper stamping components 5, which are installed between two mounting plates 3 respectively. The three upper stamping components 5 are located to the left, right and above the support component 4 respectively, and their directions are perpendicular to each other. The three form three orthogonal directions with an included angle of 90 degrees.

[0031] Each upper stamping assembly 5 includes an upper mounting base 501 and an upper stamping cylinder 502 installed at the upper mounting base 501. The upper mounting base 501 is fixed to the mounting surface of the mounting plate 3 located on the rear side. An upper connecting base 503 is installed at the output end of the upper stamping cylinder 502. The upper connecting base 503 is slidably installed on the mounting surface of the mounting plate 3. An upper stamping die 504 adapted to the upper bottom die 8 is installed at the end of the upper connecting base 503 near the support assembly 4.

[0032] It should be noted that the number and angle of the upper stamping components 5 are adjusted according to the actual U-shaped end copper wire span and number.

[0033] Both sides of the top of the support component 4 are provided with lower end stamping components 6 for stamping the lower end of the wave winding sleeve.

[0034] In detail, the lower stamping assembly 6 includes two lower mounting seats 601, which are symmetrically distributed about the Y-axis of the mounting surface of the mounting plate 3 and are fixed to the mounting plate 3 at an angle of 45 degrees with the Y-axis. A lower stamping cylinder 602 is installed on the top of the lower mounting seat 601. A lower connecting seat 603 is fixed to the output end of the lower stamping cylinder 602. The lower connecting seat 603 is slidably connected to the mounting surface of the mounting plate 3. A lower stamping die 604 adapted to the lower bottom die 9 is installed at the end of the lower connecting seat 603 near the support assembly 4.

[0035] Both sides of the bottom of the support component 4 are provided with side end stamping components 7 for side end stamping of the wave winding sleeve.

[0036] In detail, the side stamping assembly 7 includes two side mounting plates 701 that are respectively set at an angle of 45 degrees to the upper stamping assembly 5 on the same side. The side mounting plates 701 are mounted on the mounting surface of the mounting plate 3. Each side mounting plate 701 is equipped with a side stamping cylinder 702. The output end of the side stamping cylinder 702 is equipped with a side stamping die 703 that is adapted to the side bottom die 10.

[0037] The 3D stamping forming equipment for the corrugated wire sleeve described in this embodiment places the pre-formed corrugated wire sleeve outside the inner mold base 402. The wire support block 404 is moved by the wire-bearing cylinder 403, causing it to limit the copper wire through a U-shaped groove. Subsequently, the upper stamping cylinder 502, lower stamping cylinder 602, and side stamping cylinder 702 work synchronously, pushing their respective connected upper stamping dies 504, lower stamping dies 604, and side stamping dies 703 to stamp the upper bottom die 8, lower bottom die 9, and side bottom die 10 within the corrugated wire sleeve, respectively, thus achieving the stamping forming operation of the corrugated wire sleeve. The formed corrugated wire sleeve is as follows: Figure 4 As shown.

[0038] It should be noted that the structure described in this invention can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the description and drawings of this invention, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this invention.
