Description

Technical Field

[0002] At present, the lamination forming equipment for three-phase asynchronous motor cores for nylon plastic fan blades mostly adopts a static pressing process, stacking and pressing silicon steel sheets layer by layer through hydraulic or mechanical pressure. This type of equipment usually relies on fixed molds and rigid ejection mechanisms to complete the core forming. Its design is mainly to meet basic lamination requirements, with a relatively simple structure, suitable for standardized mass production.

[0003] Traditional equipment usually relies on unidirectional pressure to press silicon steel sheets, and cannot achieve fine-tuning of the stacking in the horizontal direction. It is easy to cause misalignment between core layers due to cumulative errors, affecting the uniformity of the magnetic circuit. There is no active adjustment function in the vertical direction. The control of the stacking gap relies on manual intervention, which can easily reduce the overall density and mechanical strength of the core. The demolding process uses a rigid ejector structure with a fixed size, which is difficult to adapt to cores with different inner diameters or special shapes. The mold needs to be replaced frequently, increasing downtime and production costs. Traditional ejector components (such as metal push rods) lack elastic buffering and are prone to fatigue fracture due to long-term impact loads, resulting in reduced equipment stability.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 10 As shown, the present invention provides a laminating and forming device for a three-phase asynchronous motor core for a nylon plastic fan blade, comprising an operating table 1, a laminating table 2 is fixedly installed on the top of the operating table 1, a rectangular groove 1 201, a rectangular groove 202, and a rectangular groove 3 203 are sequentially opened inside the laminating table 2 from top to bottom, a laminating machine 204 and an annular base 3 are fixedly installed on the top of the laminating table 2, a core stripping mechanism is arranged on the top of the laminating table 2, and a shaking mechanism is arranged inside the rectangular groove 1 201, the rectangular groove 202, and the rectangular groove 3 203; The shaking mechanism includes a power component and a movable component. The movable component includes a flower groove column 9 slidably installed inside the rectangular groove 1 201. The bottom end of the flower groove column 9 extends into the rectangular groove 202. The flower groove column 9 is located on the outer wall of the rectangular groove 1 201 and a disc 2 10 is slidably installed. A plurality of convex columns 11 are fixedly installed on the top of the disc 2 10. A plurality of movable grooves 205 are opened on the top of the stacking platform 2. The plurality of convex columns 11 respectively penetrate the corresponding movable grooves 205 and are connected to the corresponding sliding grooves. The rectangular groove 201 is movably connected, and the bottom inner wall of the rectangular groove 201 and the side of the disc 2 10 close to each other are respectively provided with hemispherical blocks 1001, and the sides of the two groups of hemispherical blocks 1001 close to each other are spherical and the two groups of hemispherical blocks 1001 are designed to be distributed at intervals. The groove design of the disc 2 10 in contact with the flower slot column 9 is adapted to the outer wall of the flower slot column 9, that is, the outer wall of the flower slot column 9 is designed with semicircular grooves distributed at equal distances around the circumference, and the grooves in contact with the disc 2 10 and the flower slot column 9 are respectively designed with semicircular protrusions at equal distances.

[0021] By setting rectangular groove 1 201, rectangular groove 202, and rectangular groove 3 203, installation space is provided for each functional component. By setting the flower groove column 9 into a cross-layer linkage structure, semicircular grooves are distributed on the outer wall of the flower groove column 9 at equal distances. The grooves are perfectly matched with the semicircular protrusions on the disc 2 10, ensuring the stable and flexible sliding of the disc 2 10 on the flower groove column 9. A number of protrusions 11 fixedly installed on the top of the disc 2 10 realize direct contact with the iron core through the movable groove 205 on the top of the stacking platform 2. These protrusions 11 can drive the iron core to move under the action of the shaking mechanism. Slight horizontal and vertical movements are made to achieve precise alignment of the iron core. Hemispherical blocks 1001 are respectively arranged on the inner wall of the bottom of the rectangular slot 201 and the side close to the disc 2 10. The design of two groups of hemispherical blocks 1001 realizes the reciprocating motion of the disc 2 10 in the vertical direction. When the power component drives the flower slot column 9 to rotate, the semicircular protrusions on the disc 2 10 slide in the semicircular grooves of the flower slot column 9 and are lifted by the hemispherical blocks 1001, causing the disc 2 10 and the protrusions 11 to produce complex shaking motions. This form of motion effectively promotes the alignment and tight stacking of the iron core.

[0022] like Figures 1 to 10 As shown, the power assembly includes a motor 7 fixedly mounted on the bottom inner wall of the rectangular slot three 203, the output shaft of the motor 7 extends into the rectangular slot two 202, a double-sided gear plate 8 is fixedly mounted on the output shaft of the motor 7, the bottom of the double-sided gear plate 8 is rotatably connected to the inner wall of the rectangular slot two 202, the bottom end of the flower slot column 9 is rotatably connected to the inner wall of the double-sided gear plate 8, a gear column 12 is fixedly sleeved on the bottom outer wall of the flower slot column 9, the double-sided gear plate 8 has a total of two circles of teeth, one circle is located on the inner wall of the outer wall of the double-sided gear plate 8, and the other circle is located on the outer wall of the middle cylinder of the double-sided gear plate 8, the two circles of teeth have three groups respectively, and are staggered and distributed with the axis of the double-sided gear plate 8 as the center, the gear column 12 is located in the middle of the two circles of teeth of the double-sided gear plate 8, the gear column 12 continuously meshes with the inner and outer circle teeth on the double-sided gear plate 8 during the rotation of the double-sided gear plate 8, and the two circles of teeth rotate in opposite directions when meshing with the gear column 12.

[0023] By setting up a power component and providing initial power through the motor 7, the bottom end of the groove column 9 is rotationally connected with the inner wall of the double-sided gear plate 8, thereby enhancing the stability of the structure. By setting two circles of teeth on the double-sided gear plate 8, one circle of teeth is located on the inner wall of the outer wall of the double-sided gear plate 8, and the other circle of teeth is located on the outer wall of the middle cylinder of the double-sided gear plate 8, and both are staggered and distributed with the axis of the double-sided gear plate 8 as the center, so that the gear column 12 can continuously mesh with the inner and outer ring teeth on the double-sided gear plate 8 during the rotation of the double-sided gear plate 8. When the gear column 12 meshes with the inner and outer ring teeth on the double-sided gear plate 8, the rotation direction is opposite, which not only realizes the transmission of power, but also provides the required complex motion form for the subsequent transmission mechanism through the meshing of gears and the change of rotation direction.

[0024] like Figures 1 to 10 As shown, the core-removing mechanism includes a plurality of waist-shaped ring blocks 401 fixedly mounted on the top of the stacking platform 2, the inner walls of the plurality of waist-shaped ring blocks 401 are respectively slidably mounted with moving blocks 402, the tops of the plurality of moving blocks 402 are respectively fixedly mounted with arc-shaped strip blocks 403 and T-shaped columns 404, two adjacent arc-shaped strip blocks 403 are elastically connected by a metal mesh 41, a rotating rod 5 is rotatably mounted on the top of the stacking platform 2, the bottom end of the rotating rod 5 extends into the rectangular groove 201, a disk 501 is fixedly sleeved on the outer wall of the rotating rod 5, a plurality of arc-shaped grooves 502 are opened on the top of the disk 501, and the corresponding T-shaped columns 404 respectively penetrate the corresponding arc-shaped strip blocks 403 and T-shaped columns 404. The corresponding arc groove 502 is slidably connected with the corresponding arc groove 502, a bevel gear 503 is fixedly sleeved on the bottom outer wall of the rotating rod 5, and a rotating rod 2 6 is rotatably installed on the top inner wall of the rectangular groove 201. The end of the rotating rod 2 6 close to the rotating rod 5 is fixedly sleeved with a bevel gear 2 601, and the other end of the rotating rod 2 6 extends out of the rectangular groove 201 and is rotatably connected to the stacking table 2. An adjusting bin 4 is fixedly installed on the top of the rotating rod 5, and a disc 501 is located inside the adjusting bin 4 and is rotatably connected to the adjusting bin 4. Several arc strips 403 are cylindrical when contracted, and the outer walls of several arc strips 403 are all polished.

[0025] By setting up the core-stripping mechanism, a stable sliding track is provided for the moving block 402 through a plurality of waist-shaped ring blocks 401, ensuring that the moving block 402 can move smoothly along a predetermined path when subjected to external force, thereby driving the arc-shaped bar block 403 and the T-shaped column 404 to move in an orderly manner. When the rotating rod 15 drives the T-shaped column 404 to slide through the disc 1501 and the arc-shaped groove 502, the moving block 402 slides in the waist-shaped ring block 401, thereby driving the arc-shaped bar block 403 to expand or contract. Two adjacent arc-shaped bar blocks 403 are elastically connected through the metal mesh 41, so that the arc-shaped bar block 403 can maintain a certain elasticity when contracting, thereby better adapting to iron cores of different sizes. The elastic connection of the metal mesh 41 is also The connection strength between the arc-shaped strips 403 is enhanced, and the stability and durability of the core-stripping mechanism are improved. The power transmission is realized through the meshing of the rotating rod 1 5 and the rotating rod 2 6 through the bevel gear 1 503 and the bevel gear 2 601, and the transmission mechanism is simplified. By rotating the rotating rod 2 6, the rotating rod 1 5 and the disk 1 501 can be easily driven to rotate, so as to realize the expansion or contraction control of the arc-shaped strip 403. The design of the regulating bin 4 provides additional support and protection for the disk 1 501. The outer walls of the arc-shaped strips 403 are polished to improve the smoothness of the arc-shaped strips 403 and reduce the friction resistance between them and the core A, which helps to reduce the damage to the surface of the core A during the core-stripping process and improve the quality of the core A.

[0026] The working principle and use process of the present invention: First, rotate the rotating rod 2 6 so that the rotating rod 2 6 drives the bevel gear 2 601 to rotate, and through the meshing of the bevel gear 2 601 and the bevel gear 1 503, the bevel gear 1 503 and the rotating rod 1 5 are driven to rotate, and the rotating rod 1 5 drives the disk 1 501 to rotate. When the disk 1 501 rotates, due to the setting of the arc groove 502, the rotation of the disk 1 501 drives a number of T-shaped columns 404 to slide in the corresponding arc groove 502, and the T-shaped columns 404 drive the corresponding moving blocks 402 to slide in the waist-shaped ring block 401, and the moving blocks 402 drive the corresponding arc-shaped strips 403 to move together. When the moving blocks 402 move to the top of the outer side of the waist-shaped ring block 401, a number of arc-shaped strips 403 separate from the cylindrical shape in the initial state, and the metal mesh 41 is stretched to form a larger cylinder. Figure 3As shown, the iron core A is sequentially sleeved in a cylinder composed of a plurality of arc-shaped strips 403, and the bottom iron core A is located above the annular base 3. Usually, in order to facilitate the stacking of the iron core A, two cylindrical protrusions are stamped on its surface when stamping the iron core A, so that the upper and lower iron cores can be better stacked. When stacking, the motor 7 can be started, and the output shaft of the motor 7 rotates to drive the double-sided gear plate 8 to rotate. Through the design of the inner and outer teeth of the double-sided gear plate 8, the gear column 12 is made to reciprocate clockwise and counterclockwise, and the gear column 12 drives the disc 2 10 and the protruding column 11 to rotate. When the disc 2 10 reciprocates clockwise and counterclockwise, the hemispherical block 1001 at the bottom of the disc 2 10 moves therewith. When the hemispherical block 1001 at the bottom of the disc 2 10 contacts the hemispherical block 1001 on the bottom inner wall of the rectangular groove 1 201, the disc 2 10 and the protruding column 1 1 is pushed upward, and after being staggered, the disc 201 and the protruding column 11 fall down and reset, so that the protruding column 11 moves back and forth in the horizontal direction in the movable groove 205, and at the same time, it reciprocates up and down in the vertical direction under the influence of the hemispherical block 1001. The composite movement of the protruding column 11 affects the stacked iron core A, so that the iron core A, which may have been misaligned with the upper and lower layers of protrusions and the hole grooves due to improper stacking, is gradually aligned under the action of the protruding column 11. After the alignment is completed, the laminating machine 204 laminates the iron core A column to ensure the stability and accuracy of the iron core A column. After the alignment, the iron core A column is laminated and formed by the laminating machine 204. After completion, in order to facilitate the removal of the iron core A column, the rotating rod 206 is rotated in the opposite direction to shrink and reset a plurality of arc-shaped strips 403, so that the arc-shaped strips 403 are separated from the iron core A column.
