[0058] See also Figures 1 to 3 , Figure 1 The flat wire 200 in FIG. 1 is the final shape of the flat wire 200 produced by the flat wire stamping and forming device 100 of the present application.

[0059] like Figures 1 to 3As shown, the final shape of the flat wire 200 after stamping is roughly U-shaped, and the final shape of the flat wire 200 includes three parts: the first part: the middle part 201 of the flat wire; the second part: the two ends 202 of the flat wire; the third part: the transition part 203 connecting the middle part 201 of the flat wire and the two ends 202 of the flat wire respectively.

[0060] The middle portion 201 of the flat wire is roughly V-shaped. The middle portion 201 of the flat wire includes a middle section 2011 and a first connecting section 2012 and a second connecting section 2013 respectively connected to the two ends of the middle section 2011. The middle section 2011 is curved, and the first connecting section 2012 and the second connecting section 2013 both have a certain curvature.

[0061] The two ends 202 of the flat wire are respectively a first end 2021 and a second end 2022 , and both the first end 2021 and the second end 2022 are straight lines.

[0062] The transition portion 203 of the flat wire includes a first curved segment 2031 and a second curved segment 2032, one side of the first curved segment 2031 is connected to the first end 2021, and the other side of the first curved segment 2031 is connected to the first connecting segment 2012; one side of the second curved segment 2032 is connected to the second end 2022, and the other side of the second curved segment 2032 is connected to the second connecting segment 2013.

[0063] See also Figure 4 and Figure 5The flat wire stamping and forming device 100 provided in this application is now described. The flat wire stamping and forming device 100 includes a frame 10, a support base 20, a forming base 30, a first stamping mechanism 40, a second stamping mechanism 50, a third stamping mechanism 60 and a fourth stamping mechanism 70. The support seat 20 is installed on the frame 10, and the support seat 20 is used to support the flat wire 200. The forming seat 30 is installed on the frame 10. The forming seat 30 is provided with a first V-shaped surface 33, a first curved surface 321, a limiting surface 312, a forming surface 311 and a first curved surface 322. The first V-shaped surface 33 is used to bend the middle part 201 of the flat wire so that the middle part 201 of the flat wire forms a shape that matches the first V-shaped surface 33. The first curved surface 321 is used to adjust the bending curvature of the middle part 201 of the flat wire. The limiting surface 312 is located on opposite sides of the first V-shaped surface 33. The forming surface 311 is used to cooperate with the limiting surface 312 to limit the bending path of the two ends 202 of the flat wire. The first curved surface 322 is used to bend the transition part 203 from the middle part 201 of the flat wire to the two ends 202 of the flat wire. That is to say, first use the first V-shaped surface 33 to bend the middle part 201 of the flat wire, then use the first curved surface 321 to adjust the bending curvature of the middle part of the flat wire 200, and then use the first curved surface 322 to bend the transition part 203 from the middle part 201 of the flat wire to the two ends 202 of the flat wire, and finally use the limiting surface 312 and the forming surface 311 to cooperate in bending the two ends 202 of the flat wire to complete the stamping forming of the flat wire 200.

[0064] The first stamping mechanism 40 includes a first press platform 41 and a first drive assembly installed on the frame 10. The first drive assembly is used to drive the first press platform 41 to extrude the flat wire 200 toward the first V-shaped surface 33, so that the first V-shaped surface 33 on the forming seat 30 cooperates with the first press platform 41 to extrude the middle part 201 of the flat wire, and then the middle part 201 of the flat wire is tightly attached to the first V-shaped surface 33, thereby realizing that the middle part of the flat wire 200 forms a shape that is compatible with the first V-shaped surface 33.

[0065] The second stamping mechanism 50 includes a second press platform 51 and a second drive assembly installed on the frame 10. The second drive assembly is used to drive the second press platform 51 to move in a direction perpendicular to the movement of the first press platform 41, and the second drive assembly drives the second press platform 51 to extrude the flat wire 200 in the direction of the first curved surface 321 to adjust the bending curvature of the middle part 201 of the flat wire. That is, after the first press platform 41 cooperates with the first V-shaped surface 33 to extrude the middle part 201 of the flat wire, the second drive assembly drives the second press platform 51 to extrude the flat wire 200 in the direction of the first curved surface 321 to adjust the bending curvature of the middle part of the flat wire 200, so that the middle part 201 of the flat wire forms a specific curved shape on the basis of bending, that is, the middle section 2011 of the flat wire 200 and the first connecting section 2012 and the second connecting section 2013 form a shape with a certain torsion angle, so that the flat wire 200 can be subsequently assembled on the motor stator.

[0066] The third stamping mechanism 60 includes a third press platform 61 and a third drive assembly installed on the frame 10. The third drive assembly is used to drive the third press platform 61 to move in a direction parallel to the movement of the second press platform 51, and the third drive assembly drives the third press platform 61 to move toward the first curved surface 322 to bend the transition portion 203 of the flat wire. That is to say, after the second press platform 51 extrude the middle portion 201 of the flat wire to shape it, the third drive assembly drives the third press platform 61 to move toward the first curved surface 322, so that the third press platform 61 cooperates with the first curved surface 322 on the forming seat 30 to extrude the transition portion 203 of the flat wire to bend the transition portion 203 of the flat wire.

[0067] The fourth stamping mechanism 70 includes a fourth drive assembly and two extrusion assemblies 71. The fourth drive assembly is installed on the frame 10. The two extrusion assemblies 71 are respectively arranged on opposite sides of the first press platform 41. The fourth drive assembly drives the two extrusion assemblies 71 to move parallel to the direction of movement of the first press platform 41. In addition, the fourth stamping assembly drives the two extrusion assemblies 71 to move toward the forming surface 311, so that the two extrusion assemblies 71 respectively extrude the two ends 202 of the flat wire on the corresponding forming surface 311, and the forming surface 311 cooperates with the limiting surface 312 to achieve the shaping of the two ends 202 of the flat wire.

[0068] The flat wire stamping and forming device 100 provided in the present application is compared with the prior art. The flat wire stamping and forming device 100 provided in the present application is provided with a first V-shaped surface 33, a first curved surface 321, a limiting surface 312, a forming surface 311 and a first curved surface 322 on the forming seat 30. The first pressing platform 41 is driven by the first driving component to move toward the first V-shaped surface 33, so that the flat wire 200 is closely attached to the first V-shaped surface 33 to bend the middle portion 201 of the flat wire; the second pressing platform 51 is driven by the second driving component to squeeze the middle portion 201 of the flat wire toward the first curved surface 321, so that the middle portion 201 of the flat wire is bent. A specific curvature is formed to adjust the curvature of the middle part 201 of the flat wire; the third pressing platform 61 is driven by the third driving component to move toward the first curved surface 322 to bend the transition part 203 of the flat wire, and the extrusion component 71 is driven by the fourth driving component to move toward the forming surface 311, so that each extrusion component 71 respectively squeezes the two ends 202 of the flat wire on the corresponding forming surface 311, so that the forming surface 311 cooperates with the limiting surface 312 to realize the shaping of the two ends 202 of the flat wire, and then realizes the bending shaping of the middle part 201 of the flat wire, the transition part 203 of the flat wire and the two ends 202 of the flat wire. The flat wire stamping and forming device 100 of the present application realizes the stamping and forming of the flat wire 200 with a complex shape through the forming seat 30, the first stamping mechanism 40, the second stamping mechanism 50, the third stamping mechanism 60 and the fourth stamping mechanism 70, thereby improving the automation effect of the stamping and forming process of the flat wire 200 with a complex shape, thereby improving the efficiency of the stamping and forming of the flat wire 200, and also improving the accuracy of the bending of the flat wire 200.

[0069] In one embodiment, see Figure 6 、 Figure 7 、 Figure 10 and Figure 11The forming seat 30 includes a body 31 and a forming plate 32. The body 31 is mounted on the frame 10. A first V-shaped surface 33 is provided at one end of the body 31. Limiting surfaces 312 are provided on opposite sides of the body 31. A forming surface 311 is provided on the side of the body 31 facing the third press plate 61, corresponding to the limiting surface 312. In other words, when the third press plate 61 moves toward the first curved surface 322, the third press plate 61 simultaneously slides on the limiting surface 312 until it moves to a position close to the forming surface 311. This allows the third press plate 61, the limiting surface 312, and the forming surface 311 to cooperate in defining the bending path of the two ends 202 of the flat wire. The forming plate 32 is fitted onto the first V-shaped surface 33, so that the forming plate 32 has a V-shape that matches the first V-shaped surface 33. A first curved surface 321 is provided on the side of the forming plate 32 facing the second press plate 51, corresponding to the first V-shaped surface 33. This facilitates the compression of the central portion 201 of the flat wire by the forming plate 32 and the second press plate 51, thereby adjusting the curvature of the central portion 201 of the flat wire. A first curved surface 322 is provided between each forming surface 311 and the first curved surface 321. Specifically, the first curved surfaces 321, first curved surfaces 322, and forming surfaces 311 are smoothly connected, ensuring smooth and seamless bending of the central portion 201, ends 202, and transition portion 203 of the flat wire.

[0070] Further, see Figure 12 A second V-shaped surface 42 that mates with the first V-shaped surface 33 is provided on the side of the first pressing platform 41 near the first V-shaped surface 33. The first V-shaped surface 33 and the second V-shaped surface 42 cooperate to squeeze the middle portion 201 of the flat wire, thereby forming the middle portion 201 of the flat wire into a V-shape that matches the first V-shaped surface 33 and the second V-shaped surface 42. Furthermore, when the first V-shaped surface 33 on the main body 31 and the second V-shaped surface 42 on the first pressing platform 41 cooperate to squeeze the middle portion 201 of the flat wire, the forming surface 311 is positioned between the first V-shaped surface 33 and the second V-shaped surface 42 to prevent the first pressing platform 41 from excessively squeezing the flat wire 200, which could cause severe deformation of the flat wire 200 and affect its performance. It is understood that the bending shape of the flat wire 200 can be adjusted by replacing the forming seat 30, thereby achieving stamping of flat wires 200 of different shapes.

[0071] In one embodiment, the body 31 and the forming plate 32 are an integrally formed structure, which is convenient for production and manufacturing.

[0072] In one embodiment, see Figure 7 and Figure 13The second pressing platform 51 includes a platform body 511 connected to the second driving assembly and an inserting plate 512 protruding from the platform body 511. The inserting plate 512 is formed with a second curved surface 5121 that cooperates with the first curved surface 321 to squeeze the flat wire 200 to adjust the curvature of the middle portion 201 of the flat wire. In other words, when the first pressing platform 41 and the body 31 cooperate to squeeze the middle portion 201 of the flat wire, the second driving assembly drives the inserting plate 512 protruding from the platform body 511 to be inserted between the first pressing platform 41 and the body 31, so that the forming plate 32 and the inserting plate 512 cooperate to squeeze the middle portion 201 of the flat wire. Since the forming plate 32 is provided with the first curved surface 321 and the inserting plate 512 is provided with the second curved surface 5121 that cooperates with the first curved surface 321, the middle portion 201 of the flat wire ultimately takes on a shape that is compatible with the first curved surface 321 and the second curved surface 5121, thereby forming a specific curved shape on the basis of the bending. It is understandable that the thickness of the forming plate 32 is equal to the thickness of the inserting plate 512 and the thickness of the flat wire 200 , which can avoid excessive squeezing of the flat wire 200 and make the middle portion 201 of the flat wire better fit the shape of the first V-shaped surface 33 .

[0073] In one embodiment, the platform 511 and the inserting plate 512 are integrally formed to facilitate production and manufacturing.

[0074] In one embodiment, see Figures 14 to 16 The third press platform 61 is provided with a second curved surface 6131 which cooperates with the first curved surface 322 to extrude the transition part 203 of the flat wire. That is to say, the transition part 203 of the flat wire is extruded by the second curved surface 6131 on the third press platform 61 and the first curved surface 322 on the forming plate 32, so that the transition part 203 of the flat wire can be better formed.

[0075] In one embodiment, see Figures 14 to 16The third press platform 61 includes a support block 611, a first U-shaped platform 612 and a second U-shaped platform 613. The support block 611 is connected to the third driving assembly. The first U-shaped platform 612 is placed on the support block 611. The second U-shaped platform 613 is elastically installed on the support block 611. The second U-shaped platform 613 is arranged side by side with the first U-shaped platform 612. Both ends of the first U-shaped platform 612 slide along the limiting surface 312, and both ends of the first U-shaped platform 612 have an extrusion surface 6121. Each extrusion surface 6121 cooperates with the corresponding forming surface 311 to limit the two ends 202 of the flat wire, that is, when When the third drive assembly drives the support block 611 to move toward the first curved surface 322, the two ends of the first U-shaped platform 612 slide along the limiting surfaces 312 on opposite sides of the body 31 until the two ends of the first U-shaped platform 612 are close to the forming surface 311, with a distance of approximately the diameter of a flat wire 200. At this time, the extrusion surfaces 6121 at the two ends of the first U-shaped platform 612 cooperate with the forming surface 311, thereby defining the bending path of the two ends 202 of the flat wire, making it easier for the fourth drive assembly to drive each extrusion assembly 71 to extrude the two ends 202 of the flat wire, thereby facilitating the bending of the two ends 202 of the flat wire. A second curved surface 6131 is provided at each end of the second U-shaped platform 613. When the third drive assembly drives the support block 611 to move toward the first curved surface 322, the second curved surface 6131 on the second U-shaped platform 613 cooperates with the first curved surface 322 on the forming plate 32 to extrude the transition portion 203 of the flat wire, thereby bending the transition portion 203 of the flat wire.

[0076] In one embodiment, see Figures 14 to 16 The extrusion surfaces 6121 at both ends of the first U-shaped platform 612 are arc-shaped, that is, the shape of the extrusion surface 6121 matches the shape of the outer surface of the flat wire 200 , so that the two ends 202 of the flat wire are placed on the extrusion surface 6121 .

[0077] In one embodiment, the molding surface 311 on the molding seat 30 has a certain inclination, and the side of the molding surface 311 close to the extrusion assembly 71 is inclined from the direction close to the third press platform 61 to the direction away from the third press platform 61. When the extrusion assembly 71 extrude the two ends 202 of the flat wire, the molding surface 311 with an inclination can better guide the two ends 202 of the flat wire to be placed on the molding surface 311, which is more convenient for the molding of the two ends 202 of the flat wire.

[0078] In one embodiment, see Figure 10 and Figure 11, guide blocks 6134 are respectively provided at both ends of the second U-shaped platform 613, and the guide blocks 6134 protrude from the corresponding ends of the second U-shaped platform 613. The positions of the first curved surfaces 322 on the opposite sides of the main body 31 are provided with sliding grooves 34 for guiding the movement of the guide blocks 6134. When the third driving assembly drives the third pressing platform 61 to move toward the first curved surface 322, the guide blocks 6134 at both ends of the second U-shaped platform 613 move in the sliding grooves 34, which can better guide the second curved surfaces 6131 at both ends of the second U-shaped platform 613 to cooperate with the first curved surface 322 on the forming plate 32, so as to better bend the transition part 203 of the flat wire.

[0079] In one embodiment, see Figures 14 to 16 The third pressing platform 61 also includes a mounting shaft 614 and an elastic member 615 sleeved on the mounting shaft 614. A first mounting hole 6111 is provided on the support block 611. One end of the elastic member 615 is installed in the first mounting hole 6111. A mounting groove 6132 is provided on the side of the second U-shaped platform 613 facing the support block 611. The mounting groove 6132 is used to limit the other end of the elastic member 615 to prevent the elastic member 615 from falling off the second U-shaped platform 613. A second mounting hole 6133 is provided at the bottom of the mounting groove 6132, and the mounting shaft 614 is installed in the second mounting hole 6133. When the second U-shaped platform 613 is in a non-working state, the elastic force of the elastic member 615 makes the height of the second U-shaped platform 613 higher than the first U-shaped platform 612. When the third driving component drives the support block 611 to move toward the first curved surface 322, the two ends of the second U-shaped platform 613 move along the opposite sides of the main body 31 respectively until the second curved surfaces 6131 at both ends of the second U-shaped platform 613 contact the flat wire 200. At this time, the third driving component continues to drive the support block 611 to move. Under the elastic force of the elastic member 615, the second U-shaped platform 613 compresses the elastic member 615 downward, and the mounting shaft 614 moves downward a certain displacement in the first mounting hole 6111 until the second U-shaped platform 613 contacts the support block 611. At this time, the second curved surface 6131 on the second U-shaped platform 613 bends the transition portion 203 of the flat wire with a larger extrusion force, so that the transition portion 203 of the flat wire is formed. Because the flat wire transition portion 203 has a large curvature, the elastic member 615, provided on the second curved surface 6131 of the second U-shaped platform 613, provides a buffer when contacting the first curved surface 322 of the forming plate 32. This prevents the second U-shaped platform 613 from exerting excessive pressure when contacting the flat wire transition portion 203, potentially damaging the flat wire 200. The mounting shaft 614 guides the second U-shaped platform 613, allowing the elastic member 615 to be accurately compressed downward along the path between the first mounting hole 6111 and the second mounting hole 6133.

[0080] In one embodiment, see Figure 15The elastic member 615 is a spring, which has a simple structure, is easy to install, and has good spring elasticity to provide a buffer. Of course, the elastic member 615 can also be made of a material with good elasticity, such as silicone or rubber.

[0081] In one embodiment, see Figure 10 and Figure 14 A guide shaft 6122 is provided on the first U-shaped platform 612, and a guide hole 313 is provided on the main body 31 for the guide shaft 6122 to pass through. When the third driving assembly drives the third pressing platform 61 to move toward the first curved surface 322, the guide shaft 6122 on the first U-shaped platform 612 is inserted into the guide hole 313 on the main body 31 to position the first U-shaped platform 612, so that the movement of the first U-shaped platform 612 is more precise.

[0082] In one embodiment, see Figures 7 to 9 Each extrusion assembly 71 includes a mounting block 711 and an extrusion member 712. The mounting block 711 is arranged on the fourth driving assembly, and the extrusion member 712 is arranged on the mounting block 711. When the fourth driving assembly drives the mounting block 711 to move toward the forming surface 311, it drives the extrusion member 712 to move toward the forming surface 311, so that each extrusion member 712 squeezes the two ends 202 of the flat wire on the corresponding forming surface 311.

[0083] Optionally, the end of the extrusion member 712 facing the forming seat 30 away from the second press platform 51 is tilted toward the forming seat 30, that is, an angle is formed between the side of the extrusion member 712 that extrude the two ends 202 of the flat wire and the forming seat 30, so that the extrusion member 712 extrude the two ends 202 of the flat wire onto the forming surface 311. The extrusion member 712 can be an irregular shape or an inverted triangle.

[0084] Furthermore, the mounting block 711 is provided with an inclined surface 7111. The side of the inclined surface 7111 near the first press plate 41 is inclined from a direction away from the second press plate 51 to a direction close to the second press plate 51. That is, the inclined surface 7111 on the mounting block 711 is inclined toward the first press plate 41, and the inclined surfaces 7111 on the mounting blocks 711 located on opposite sides of the first press plate 41 are inclined toward each other, so that an angle is formed between a surface of the extrusion member 712 that extrudes the ends 202 of the flat wire and the forming seat 30, so that the extrusion member 712 extrude the ends 202 of the flat wire onto the forming surface 311. The extrusion member 712 is rollingly mounted on the inclined surface 7111, so that when the extrusion member 712 extrudes the ends 202 of the flat wire, rolling contact is achieved, thereby reducing friction between the extrusion member 712 and the flat wire 200. In some embodiments, the extrusion member 712 can be a rolling bearing, or a roller, etc.

[0085] In one embodiment, the first driving component may be a linear drive such as a pneumatic cylinder, an electric cylinder, or a linear motor.

[0086] In one embodiment, the second driving component may be a linear drive such as a pneumatic cylinder, an electric cylinder, or a linear motor.

[0087] In one embodiment, the third driving component may be a linear drive such as a pneumatic cylinder, an electric cylinder, or a linear motor.

[0088] In one embodiment, the fourth driving component may be a linear drive such as a pneumatic cylinder, an electric cylinder, a linear motor, etc., or may be a linear guide type linear module or a synchronous belt type linear module.

[0089] In one embodiment, see Figures 4 to 7 On the frame 10, support rods 11 are respectively provided on opposite sides of the forming seat 30. The two support rods 11 cooperate with the support seat 20 to support the flat wire 200 so that the flat wire 200 remains horizontal and ensures the accuracy of the extrusion angle of the flat wire 200.

[0090] The above description is merely an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
