Description

Technical Field

[0001] The invention belongs to the field of generator wire rods, and in particular relates to a 3D transposition automatic forming device for generator wire rods. Background Art

[0002] The multiple strands of flat copper wires inside the generator wire bar are cross-transposed in the straight section of the wire bar. By changing the spatial position of the conductor, the magnetic flux of the cross-linked strands is made as balanced as possible to generate basically equal induced potentials, so as to eliminate the internal circulation in the wire bar and reduce the wire bar loss. When the straight section flat copper wires of the wire bar are braided and transposed, the flat copper wires of the wire bar are usually arranged in two columns. Each strand of wire crosses from one column to another twice at the same interval within the entire length of the iron core, and is braided according to a certain rule so that each strand occupies all vertical positions in the two columns.

[0003] Each generator wire bar is composed of two upper and lower columns of flat copper wires, and each column includes multiple horizontally distributed flat copper wires. Therefore, each flat copper wire needs to be processed with a front 3D transposition group and a back 3D transposition group. Since each 3D transposition group needs to be vertically stamped to form an S-shaped portion, and horizontally stamped to form a U-shaped portion, due to the particularity of the structure, when processing the flat copper wires of the wire bar, a single flat copper wire needs to be positioned and clamped on a bending machine for bending and forming. Only a single wire can be bent and formed during processing, and the processing efficiency is low. Secondly, since the distance between the 3D transposition group on each flat copper wire and the end is different, the length of each processing of the bending machine is different. Therefore, multiple bending machines are required to meet the use requirements of stamping of different lengths, which greatly increases the production cost. Summary of the invention

[0052] The sliding stamping mechanism 4 includes a sliding track 41 arranged directly above the plurality of flat copper wires 100 , on which a U-shaped stamping head 43 and an S-shaped stamping head 42 which can be horizontally rotated by 180° are slidably arranged.

[0053] The 3D transposition automatic forming equipment in the present invention includes a staggered positioning mechanism 1, an overall flipping and flattening driving mechanism 2, a stamping limit mechanism 3 and a sliding stamping mechanism 4, which realizes the synchronous processing and forming of the front 3D transposition group 200 and the back 3D transposition group 300 of multiple flat copper wires 100 with unequal spacing, greatly improves the production and processing efficiency, does not need to configure multiple bending machines, and greatly reduces the production cost.

[0054] The staggered positioning mechanism 1 of the 3D transposition automatic forming equipment in the present invention staggers and positions multiple flat copper wires 100 in sequence, which is convenient for synchronously stamping the S-bend portion 400 and the U-shaped portion of the front 3D transposition group 200 and the back 3D transposition group 300, and can ensure that the 3D transposition groups on each flat copper wire form the same spacing.

[0055] During processing according to the present invention, a plurality of flat copper wires 100 are first vertically positioned on the overall flipping and flattening driving mechanism 2. After the S-bend 400 is punched out by the punching head of the sliding punching mechanism 4, a plurality of parallelogram bodies 27 of the overall flipping and flattening driving mechanism 2 are stretched to enlarge the spacing between the plurality of flat copper wires 100, thereby providing a distance space for the subsequent horizontal flipping of the flat copper wires 100. Finally, the plurality of flat copper wires 100 are horizontally flipped on the front and back sides as a whole, thereby realizing the punching of the U-shaped portions on the front and back sides at two transposition locations on each flat copper wire 100.

[0056] The positioning comb 32 of the stamping limit mechanism 3 plays a role of vertical support and positioning for the stamping of the S-bend portions 400 of the multiple vertically arranged flat copper wires 100, thereby ensuring the verticality of each vertical flat copper wire 100 when being stamped, and the setting of the horizontal support plate 33 plays a role of horizontal support for the stamping of the U-shaped portions on the multiple horizontally arranged flat copper wires 100, thereby ensuring the horizontal positioning of the flat copper wire when the U-shaped portions are stamped. Therefore, the setting of the stamping limit mechanism 3 ensures the forming accuracy of the 3D transposition group on the flat copper wire 100.

[0057] In this embodiment, refer to Figure 7 , Figure 8 The bidirectional flip assembly 29 includes a U-shaped bracket 291 arranged at the upper end of the shaft 25, the opening of the U-shaped bracket 291 is arranged upward, and a rotating shaft 292 is provided at both ends of the U-shaped bracket 291, one end of the rotating shaft 292 is connected to a forward and reverse reduction motor 293, and a connecting seat 294 is fixedly connected to the rotating shaft 292, and the connecting seat 294 has a clamping claw cylinder 295 for vertically clamping or loosening the flat copper wire 100.

[0058] In this embodiment, after the S-bend 400 of each flat copper wire 100 (each flat copper wire 100 has two 3D transposition groups, so there are two S-bends 400) is stamped, the front side of one S-bend 400 of the flat copper wire 100 needs to be stamped to form a front U-shaped portion, and the back side of the other S-bend 400 needs to be stamped to form a back U-shaped portion. Therefore, the bidirectional flipping component 29 in this application flips multiple vertically arranged flat copper wires 100 in the forward and reverse directions.

[0059] In this embodiment, a rocker limit assembly 28 is provided on the radial support 21. When the rocker 210 swings horizontally to shrink the multiple parallelogram bodies 27 to the minimum length, the rocker limit assembly 28 horizontally limits and fixes the rocker 210. When the rocker 210 swings horizontally to stretch the multiple parallelogram bodies 27 to the maximum length, the rocker limit assembly 28 horizontally limits and fixes the rocker 210.

[0060] In the present application, the length of the plurality of parallelogram bodies 27 is extended or retracted by horizontally swinging the rocker 210. When the S-bend 400 is punched, the length of the plurality of parallelogram bodies 27 is the shortest, and the spacing between the plurality of vertically arranged flat copper wires 100 is the smallest, which facilitates vertical punching. When the front U-shaped portion 500 and the back U-shaped portion 600 are punched, the horizontally swinging rocker 210 stretches the plurality of parallelogram bodies 27, and the length is the longest at this time. When the rocker 210 swings to the longest or shortest length, the rocker 210 and the rocker limit assembly 28 are positioned and fixed, and at this time the parallelogram body 27 is fixed in structure and will not be extended or retracted, which facilitates subsequent punching.

[0061] Specifically, refer to Fig.11The rocker limit assembly 28 includes a rocker limit base 281 disposed on the slide rail 22 near the rocker 210. The rocker limit base 281 has a first limit rod 282 and a second limit rod 283. When the plurality of parallelogram bodies 27 are contracted to a minimum length, the first limit rod 282 is placed directly below the rocker 210. When the plurality of parallelogram bodies 27 are extended to a maximum length, the second limit rod 283 is placed directly below the rocker 210.

[0062] The rocker limit assembly 28 also includes a limit column 284 arranged at the lower end of the rocker 210, and the first limit rod 282 and the second limit rod 283 both have a limit groove 285 that cooperates with the limit column 284 on the rocker 210. The first limit rod 282 and the second limit rod 283 are vertically connected with a pull rod 286 at the end position near the rocker limit base 281, and the end of the pull rod 286 vertically penetrates the rocker limit base 281, and the rocker limit base 281 has a cavity 287 for accommodating the reciprocating vertical movement of the pull rod 286, and the end of the pull rod 286 has a spring pressure block 288, and a spring 289 is provided between the spring pressure block 288 and the bottom of the cavity 287 and is sleeved on the outside of the pull rod 286.

[0063] When the rocker 210 needs to be rotated, the first limit rod 282 and the second limit rod 283 are pulled downward to disengage the rocker 210 from the first limit rod 282 and the second limit rod 283. When the multiple parallelogram bodies 27 are extended to the longest length or the shortest length, stop pulling the first limit rod 282 and the second limit rod 283 downward. At this time, the limit groove 285 on the first limit rod 282 or the second limit rod 283 cooperates with the limit column 284 on the rocker 210 to prevent the rocker 210 from being subjected to force and swinging horizontally.

[0064] In this embodiment, the rocker limit base 281 has a sleeve 2810 that allows the pull rod 286 to vertically pass through. The inner wall of the sleeve 2810 has a plurality of convex ribs 2811 with equal circumference distribution. The outer circumference of the pull rod 286 has an embedding groove 2812 that cooperates with the convex rib 2811. The setting of the convex rib 2811 and the embedding groove 2812 ensures the verticality of the pull rod 286 during the up and down displacement process, which facilitates the cooperation between the first limit rod 282 or the second limit rod 283 and the rocker 210.

[0065] In this embodiment, refer to Fig.10 The positioning comb 32 includes a connecting body 321 and a plurality of comb body parts 322 placed on the connecting body 321. The spacing between two adjacent comb body parts 322 is consistent with the spacing between two adjacent flat copper wires 100 when the plurality of parallelogram bodies 27 are shrunk to the minimum length. The setting of the positioning comb 32 ensures the vertical positioning of the plurality of vertically arranged flat copper wires 100 during the stamping process.

[0066] Furthermore, the inner wall of the comb body 322 has an arc-shaped clamping strip 323 that contacts the end of the flat copper wire 100. The arc-shaped clamping strip 323 is bent toward the direction of the flat copper wire 100. The setting of the arc-shaped clamping strip 323 not only facilitates the guidance of the positioning comb 32 when it is staggered with multiple vertical flat copper wires 100, but also reduces the contact friction and avoids wear on the end insulation of the flat copper wire 100.

[0068] S1. Reference Figure 4 , Fig. 9 , vertically place the ends of the plurality of flat copper wires 100 in the clamping claw cylinder 295 of the overall flipping and paving driving mechanism 2, so that the axial ends of the plurality of flat copper wires 100 sequentially contact the ends of the plurality of stop blocks 11 of the staggered positioning mechanism 1, and the ends of the adjacent flat copper wires 100 are sequentially staggered by a spacing a;

[0069] S2, the clamping claw cylinder 295 contracts, clamps and positions the flat copper wire 100, and withdraws from the blocking block 11;
