[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.

[0046] The wire pressing assembly 42 includes a cylinder sleeve seat 4201 fixedly sleeved on the outer surface of the rotating shaft 46, and the shape of the cylinder sleeve seat 4201 can be set according to the specification and shape of the wave-wound copper wire. A plurality of fifth cylinders 4202 are installed around the cylinder sleeve seat 4201, and the output end of each fifth cylinder 4202 is provided with a push rod connecting plate 4203 (the push rod connecting plate 4203 is elastically reset by the second spring 4205), and two symmetrically distributed push rods 4204 are fixedly provided on one side of the push rod connecting plate 4203 away from the adjacent fifth cylinder 4202, and one end of the push rod 4204 away from the adjacent push rod connecting plate 4203 is slidably connected to the circular mold II45;

[0047] Each push rod connecting plate 4203 is elastically connected to the circular mold II45 through a second spring 4205, and the second spring 4205 is located between two adjacent push rods 4204. A plurality of through grooves 4206 in a circular array are provided on the side of the circular mold II45 away from the fifth cylinder 4202. One end of the push rod 4204 away from the fifth cylinder 4202 extends into the through groove 4206 at the same horizontal position. Its function is that when the fifth cylinder 4202 is retracted and reset, the push rod 4204 slowly retracts from the through groove 4206 under the action of the second spring 4205. At the same time, the wire pressing block 4207 retracts into the through groove 4206 under the action of the first spring 4208 to prepare for the next wire pressing.

[0048] The interior of the through slot 4206 is provided with a wire pressing part for limiting the position of the wave-wound copper wire, the wire pressing part includes a wire pressing block 4207, a first spring 4208 and a limit block group 4209, the wire pressing block 4207 is located in the through slot 4206 and contacts the adjacent push rod 4204, and the end of the push rod 4204 that contacts the wire pressing block 4207 is an inclined surface, and the end of the wire pressing block 4207 close to the axis core of the rotating shaft 46 is an arc surface, and the inclined surface contacts the arc surface, and the inner top wall of the through slot 4206 is provided with a through hole for the wire pressing block 4207 to pass through, the wire pressing block 4207 is elastically connected to the inner wall of the through slot 4206 by the first spring 4208 fixed on both sides, and is blocked and limited by a cover plate fixed on one side of the circular mold II45 close to the circular mold connecting piece 47, and the limit block group 4209 is installed on the outer surface of the circular mold I44 and the circular mold II45;

[0049] It should be noted that the limit block group 4209 includes a lower limit block group 4209a and an upper limit block group 4209b which are symmetrically arranged on both sides of the wire hook component 41 (that is, the lower limit block group 4209a is located at the circular mold 144, and the upper limit block group 4209b is located at the circular mold II45, and the number of the lower limit block group 4209a is two, which is used to correspond to the lower ends of the two pins of the wave-wound copper wire, and the number of the upper limit block group 4209b is three, which is used to correspond to the upper ends of the three pins of the wave-wound copper wire, so as to realize the subsequent limiting and fixing operations), and the upper limit block group 4209b is provided with an inclined surface at the lower side close to the wire pressing block 4207. When the wire pressing block 4207 moves upward, the pins of the wave-wound copper wire are squeezed under the inclined surface to realize the limiting processing thereof.

[0050] The line hooking component 41 is inflated by the inflation component 48 fixed to the bottom of the top plate 2. The inflation component 48 includes a first fixing plate 4802 fixed to the bottom of the top plate 2 by a fixing column 4801. A third cylinder 4803 is installed on the top of the first fixing plate 4802, and the output end of the third cylinder 4803 passes through the top plate 2 and is fixed with a joint fixing plate 4804. Its function is that when the quick connector II4807 needs to be quickly inflated, the third cylinder 4803 pushes the interface fixing plate upward, so that the quick connector I4805 is docked with the quick connector II4807 to achieve the purpose of inflation. Two quick connectors I4805 are installed on the side of the joint fixing plate 4804 close to the line hooking component 41;

[0051] The outer side of the circular die I44 is equipped with air pipe adapter blocks 4806 corresponding to the number of wire crimping assemblies 42. Two quick connectors II4807 for connecting with the quick connector I4805 are fixedly installed at the bottom of each air pipe adapter block 4806. A group of elbows I4808 respectively connected to the quick connectors II4807 inside the same air pipe adapter block 4806 are also installed on the top of the air pipe adapter block 4806. Each group of elbows I4808 passes through the through groove 4206 and is respectively connected to the elbows II4809 at the air supply end of the clamping cylinder 4101 at the same horizontal position, which are used to supply air to the clamping cylinder 4101 of the wire hooking assembly 41, so as to achieve the purpose of taking and placing the copper wire by the wire hooking block 4102.

[0052] It should be noted that the structures of the round mold I44 and the round mold II45 are basically the same, so the structural position described in this embodiment has no effect whether the round mold I44 or the round mold II45 is used as a reference. The difference between the two lies in that the through grooves 4206 opened inside the round molds I44 and II45 are different. The connecting through groove 4210 opened at the round mold I44 is used for the penetration of the elbow I4808, and the telescopic through groove 4206 at the round mold II45 is for the placement of the wire pressing block 4207. In addition, the round mold I44 has two raised arcs, while the round mold II45 has three raised arcs. The lower end limit block group 4209a and the upper end limit block group 4209b installed at the raised arcs of the two are used to limit the lower ends of the two pins and the upper ends of the three pins of the wave-wound copper wire.

[0053] The wave-wound wire 3D preforming equipment described in this embodiment, before pre-winding, first pulls the slide plate 3202 to the outermost side of the top plate 2, places the wave-wound copper wire on the slide plate 3202, and places an outer pin of the wave-wound copper wire in the wire groove to avoid misalignment during processing, and then pushes the slide plate 3202 in the direction close to the pre-winding mechanism 4, so that the first upper end of the wave-wound copper wire is located directly below the first pair of wire pressing parts. At this time, the fourth cylinder 3205 located on the side of the upper end of the wave-wound copper wire pushes the arc-shaped lower module 3206 to slide in the direction of the pre-winding mechanism 4, so that the arc-shaped lower module 3206 is located directly below the upper end of the wave-wound copper wire, ready for pre-winding operation;

[0054] During pre-winding, the first upper end of the wave-wound copper wire is first located directly below the pre-winding mechanism 4, and the two arc-shaped lower modules 3206 are respectively located at the upper end and the lower end of the wave-wound copper wire, and the lifting cylinder 3102 pushes the lifting plate 3103 upward, so that the two arc-shaped lower modules 3206 contact the two ends of the wave-wound copper wire and push them upward, preparing to send the wave-wound copper wire into the pre-winding mechanism 4;

[0055] At this time, the fifth cylinder 4202 pushes the push rod connecting plate 4203, so that the two push rods 4204 on the push rod connecting plate 4203 are pushed into the interior of the circular mold II45, and then the wire pressing block 4207 is lifted up, and the pins on both sides of the upper end of the wave-wound copper wire are limited between the upper end limit block group 4209b and the wire pressing block 4207. The wire hooking component 41 hooks the middle part of the wave-wound copper wire through the wire hooking block 4102, and then the driving component 43 drives the rotating shaft 46 to rotate, so that the wire pressing component 42 and the wire hooking component 41 are lifted up. The component 41 rotates synchronously to realize winding of the upper end of the hooked wave-wound copper wire. After the upper end is wound, the lower end of the lifted pin is pushed to the bottom of the pre-winding mechanism 4 by the fourth cylinder 3205, and the winding work is realized synchronously through the limit of the lower end limit block group 4209a. When the next wire pressing component 42 rotates to the top of the lifting component 31, the wire pressing and hooking work is carried out on the upper end of the next wave-wound copper wire, and the whole wave-wound copper wire is pre-wound by repeating the cycle.

[0056] It should be noted that the structure described in the present invention can be implemented in a variety of different forms and is not limited to the described embodiments. Any equivalent transformations made by ordinary technicians in this field using the contents of the present invention description and drawings, or directly or indirectly applied to other related technical fields, such as the loading and unloading of other items, are included in the protection scope of the present invention.
