Description

Technical Field

[0001] The present invention belongs to the field of copper wire forming equipment, and in particular relates to a wave-wound wire 3D preforming equipment. Background Art

[0002] Stator wave winding 3D molding technology is a revolutionary innovation in motor manufacturing. By utilizing wave winding and 3D molding, it not only significantly improves motor performance but also drives the development of motor manufacturing towards automation and intelligence. As the technology continues to improve, it is expected to play an even greater role in new energy vehicles, aerospace, and renewable energy, providing solid technical support for the development of high-efficiency, energy-saving equipment.

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

[0004] However, for the traditional 3D stamping equipment, the process of directly stamping and forming the wave winding wire in the 2D state is difficult. Since the wire in the 2D state is relatively loose and easy to deform, direct use for forming may cause the winding shape to be out of control and affect the motor performance. At the same time, for the 2D-formed wave winding wire, direct 3D stamping will also cause the winding to be scattered or misaligned.

[0005] Therefore, how to ensure the stability of the overall structure of the 2D-formed wave winding wire during 3D stamping and facilitate 3D stamping is a problem that needs to be solved. Summary of the Invention

[0041] The pre-winding mechanism 4 includes a circular die I44 and a circular die II45, and several hooking wire assemblies 41 installed between the circular die I44 and the circular die II45 for fixing the wave-wound copper wire, several pressing wire assemblies 42 installed on the same side of the circular die II45 for limiting the wave-wound copper wire, and a driving assembly 43 installed on the same side of the circular die I44. The circular die I44 and the circular die II45 are respectively sleeved on both ends of the rotating shaft 46 through a fixed circular die connector 47 for synchronous rotation. It should be noted that the number of the hooking wire assemblies 41 is the same as the number of the pressing wire assemblies 42, and the same as the number of the upper ends of the wave-wound copper wire;

[0042] The details are as follows:

[0043] The thread hooking assembly 41 includes a clamping cylinder 4101 mounted on the outer ring of the circular die connector 47. The two output ends of the clamping cylinder 4101 are respectively fixedly connected to the thread hooking blocks 4102. The adjacent ends of the two thread hooking blocks 4102 are fixed with spring pillars 4103. The two spring pillars 4103 are elastically connected by a third spring 4104 to ensure the stability of the thread hooking operation. A speed control valve is also installed on the clamping cylinder 4101.

[0044] Vertical plates I6 and II7 are respectively installed on both sides of the working surface of the top plate 2. The driving assembly 43 includes a servo motor 4301, a driving gear 4302 and a follower gear 4303. The servo motor 4301 is installed on the outside of the vertical plate II7. The output end of the servo motor 4301 passes through the vertical plate II7 and extends to the inside of the vertical plate II7 and is coaxially fixed with the driving gear 4302. The follower gear 4303 is installed on the inside of the vertical plate II7 and meshes with the driving gear 4302 for transmission.

[0045] 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 specifications 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 a second spring 4205). Two symmetrically distributed push rods 4204 are fixedly provided on the side of the push rod connecting plate 4203 away from the adjacent fifth cylinder 4202, and the ends of the push rods 4204 away from the adjacent push rod connecting plate 4203 are slidably connected to the circular mold II45;

[0046] Each push rod connecting plate 4203 is elastically connected to the circular mold II45 by a second spring 4205, and the second spring 4205 is located between two adjacent push rods 4204. A plurality of through grooves 4206 in an annular 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.

[0047] The interior of the through groove 4206 is provided with a wire pressing portion for limiting the wave-wound copper wire, and the wire pressing portion 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 groove 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. A through hole is provided on the inner top wall of the through groove 4206 for the wire pressing block 4207 to pass through. The wire pressing block 4207 is elastically connected to the inner wall of the through groove 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 connector 47. The limit block group 4209 is installed on the outer surface of the circular mold I44 and the circular mold II45;

[0048] It should be noted that the limit block group 4209 includes a lower limit block group 4209a and an upper limit block group 4209b 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 I44, and the upper limit block group 4209b is located at the circular mold II45, and the number of the lower limit block groups 4209a is two, which are 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 groups 4209b is three, which are used to correspond to the upper ends of the three pins of the wave-wound copper wire, so as to realize subsequent limiting and fixing operations), and the upper limit block group 4209b is provided with an inclined surface below one 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 its limiting processing.

[0049] The line hooking assembly 41 is inflated by an inflation assembly 48 fixed to the bottom of the top plate 2. The inflation assembly 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 to a joint fixing plate 4804. Its function is that when the quick connector II 4807 needs to be quickly inflated, the third cylinder 4803 pushes the interface fixing plate upward, so that the quick connector I 4805 and the quick connector II 4807 are connected to achieve the purpose of inflation. Two quick connectors I 4805 are installed on the side of the joint fixing plate 4804 close to the line hooking assembly 41;

[0050] The outer side of the circular die I44 is equipped with air pipe adapter blocks 4806 corresponding to the number of wire pressing assemblies 42. Two quick connectors II4807 for connecting with the quick connector I4805 are fixedly installed on 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 elbow II4809 at the air supply end of the clamping cylinder 4101 at the same horizontal position, which is 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.

[0051] It should be noted that the structures of the circular mold I44 and the circular mold II45 are basically the same, so the structural position described in this embodiment has no effect whether the circular mold I44 or the circular mold II45 is used as a reference. The difference between the two is that the through grooves 4206 opened inside the circular mold I44 and the circular mold II45 are different. The connecting through groove 4210 opened at the circular mold I44 is used for the passage of the elbow I4808, and the telescopic through groove 4206 at the circular mold II45 is for the placement of the wire pressing block 4207. There are two raised arcs at the circular mold I44, and three raised arcs at the circular mold II45. 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 end portions of the two pins and the upper end portions of the three pins of the wave-wound copper wire.

[0052] The wave-wound wire 3D preforming equipment described in this embodiment, before pre-winding, first pulls the slide 3202 to the outermost side of the top plate 2, places the wave-wound copper wire on the slide 3202, and places one of the outer pins of the wave-wound copper wire in the wire groove to avoid misalignment during processing. Then, push the slide 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;

[0053] During pre-coiling, the first upper end of the wave-wound copper wire is first located directly below the pre-coiling mechanism 4, and the two arc-shaped lower modules 3206 are respectively located at the upper and lower ends of the wave-wound copper wire. 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 feed the wave-wound copper wire into the pre-coiling mechanism 4;

[0054] 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 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 the 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. 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. The whole wave-wound copper wire is pre-wound in a reciprocating cycle.

[0055] 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 scope of protection of the present invention.
