Description

Technical Field

[0001] This invention relates to the field of flat wire forming technology, and in particular to a flat wire forming equipment and forming method. Background Technology

[0002] Before being embedded into the motor core, the flat wire needs to undergo forming processing, which usually involves pressing the straight flat wire into V-shapes and U-shapes in sequence, and finally performing 3D three-dimensional forming to meet the complex winding arrangement requirements.

[0003] Currently, the industry generally adopts a step-by-step independent molding process. First, the flat wire is pressed into a V-shape on a dedicated machine. After this step, the semi-finished product needs to be removed, transferred, and positioned on a second machine for U-shaped pressing. Then, it is removed, transferred, and positioned again on a third machine for final 3D molding. Because each independent molding step requires a separate machine, the production process involves a large footprint and high costs. In addition, the flat wire needs to be transferred, reloaded, and repositioned after each process, resulting in low production efficiency.

[0055] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] The present application will be further described in detail below with reference to the accompanying drawings.

[0057] like Figure 1 , Figure 2 and Figure 3As shown in the figure, this application discloses a flat wire forming device, which includes: a main body 10, a slide rail 20, a first module 30 and a second module 40, a first pressing table 50 and a second pressing table 60, and a third module 70; the main body 10 is provided with a forming cavity 11; the slide rail 20 is disposed on the main body 10 along the y-axis direction, and one end of the slide rail 20 extends into the forming cavity 11; the first module 30 and the second module 40 are slidably disposed on the slide rail 20; the first module 30 is formed with a first V-shaped surface 311 and a first arc-shaped platform 322; the second module 40 is provided with a second V-shaped surface 421; the second V-shaped surface 421 and the first V-shaped platform 322 are connected. The profile 311 is adapted to extrude the flat wire into a V-shape; the first pressing platform 50 and the second pressing platform 60 are disposed opposite each other on the top of the forming cavity 11; the first module 30 and the second module 40 slide along the slide rail 20 into the forming cavity 11, and the first pressing platform 50 and the second pressing platform 60 abut against the two ends of the flat wire to bend the V-shaped flat wire into a U-shape; the third module 70 is slidably disposed on the main body 10 along the x-axis direction and is located in the forming cavity 11; the third module 70 forms a second arc-shaped platform 722; the second arc-shaped platform 722 is adapted to the first arc-shaped platform 322 to press the U-shaped flat wire 90 into the target shape.

[0058] In the initial state, such as Figure 2 and Figure 3 As shown, the first module 30 is located outside the molding cavity 11, and the second module 40 is located at the port of the molding cavity 11, and the second module 40 is located below the first module 30. The flat wire is placed between the first module 30 and the second module 40. The first module 30 slides along the slide rail 20 toward the second module 40, and the first V-shaped surface 311 contacts the flat wire. The first module 30 continues to slide toward the second module 40 until the first V-shaped surface 311 and the second V-shaped surface 421 bend the flat wire into a V-shape. Subsequently, the first module 30 and the second module 40 slide into the forming cavity 11 simultaneously. During this process, the first pressure plate 50 and the second pressure plate 60 located at the top of the forming cavity 11 contact the two sides of the flat wire and bend it into a U-shape. Finally, when the first module 30 and the second module 40 clamp the flat wire and move to be on the same straight line as the third module 70, the third module 70 moves along the x-direction and inserts between the first module 30 and the second module 40, pressing the U-shaped flat wire into a 3D shape. In this way, the flat wire is integrally formed through the first module 30, the second module 40 and the third module 70, improving the efficiency of flat wire forming.

[0059] In this embodiment, as Figure 4 and Figure 5As shown, the first module 30 includes: a first molding block 31, a second molding block 32, and a first driving member 33; the first molding block 31 forms a first V-shaped surface 311 and first folded surfaces 312 located on opposite sides of the first V-shaped surface 311; the first folded surfaces 312 extend outward to form a flange 3121; the second molding block 32 forms a first end face 321; the end of the first end face 321 extends outward to form a first arc-shaped platform 322; the first arc-shaped platform 322 is used to support the flat wire and the second module 40; the first end face 321 is recessed inward to form a groove 323; the groove 323 is adapted to the first molding block 31; the flange 3121 is embedded in the groove 323, and the top of the flange 3121 is flush with the first end face 321; the first driving member 33 is drively connected to the second molding block 32.

[0060] Specifically, the first molding block 31 has a first V-shaped surface 311 and first folded surfaces 312 oppositely disposed on both sides of the first V-shaped surface 311. Part of the first folded surface 312 extends outward to form a flange 3121. That is, the first molding block 31 has an overall shape that is wider at the bottom and narrower at the top. The top of the flange 3121 has an inclined surface for supporting the two ends of the flat wire. The second molding block 32 has a first end face 321. The first end face 321 is recessed inward to form a groove 323. The cross-sectional shape of the groove 323 is the same as the cross-sectional shape of the first molding block 31 so as to snap the first molding block 31 into the groove 323. The first end face 321 extends outward to form a first arc-shaped platform 322. When the first forming block 31 is inserted into the groove 323, the outer side wall of the flange 3121 fits tightly with the inner side wall of the groove 323. After the two are fitted together, the top of the flange 3121 is flush with the first arc-shaped platform 322, and the inclined surface extends just outside the groove 323. At this time, a small angle is formed between the inclined surface and the first arc-shaped platform 322, which is used to support the two ends of the flat wire. During the flat wire pressing process, it can ensure that the flat wire fits tightly with the first module 30, ensuring the accuracy of the flat wire forming.

[0061] In this embodiment, the first driving member 33 is disposed on the main body 10, and the output shaft of the first driving member 33 is connected to the second molding block 32 for driving the second molding block 32 to slide along the slide rail 20. When the first driving member 33 is activated, the second molding block 32 slides along the slide rail 20, causing the first molding block 31 to slide synchronously. In this embodiment, the first molding block 31 and the second molding block 32 are fixedly connected together by screws or snap-fits to ensure stability during operation.

[0062] In one implementation, such as Figure 6 and Figure 7As shown, the second module 40 includes a third molding block 41 and a fourth molding block 42; wherein, the third molding block 41 is connected to the second molding block 32; a first snap-fit ​​platform 411 is provided on the end face of the third molding block 41; the fourth molding block 42 forms a second V-shaped surface 421 and a second end face 422; the second V-shaped surface 421 is adapted to the first V-shaped surface 311; the second end face 422 is embedded in the first snap-fit ​​platform 411; one end of the second end face 422 extends outward to form a third arc-shaped platform 423; the third arc-shaped platform 423 is adapted to the first arc-shaped platform 322.

[0063] In use, the first snap-fit ​​platform 411 on the third molding block 41 and the second end of the fourth molding block 42 are engaged; the fourth end face extends outward toward the third molding block 41 to form a third arc-shaped platform 423. When the first mold slides to the second module 40, the first V-shaped surface 311 on the first molding block 31 and the second V-shaped surface 421 on the fourth molding block 42 are adapted to each other. At the same time, the third arc-shaped platform 423 is embedded and attached to the first arc-shaped platform 322. Subsequently, the first module 30 and the second module 40 apply opposite forces to the flat wire to compress and bend the flat wire into a V-shape through the first V-shaped surface 311 and the second V-shaped surface 421.

[0064] In this embodiment, the second driving member 43 is disposed at the bottom of the main body 10; the second driving member 43 passes through the molding cavity 11 and is connected to the fourth molding block 42. In actual production, the third molding block 41 and the second molding block 32 abut against each other. When the first module 30 and the second module 40 press the flat wire against each other, the second module 40 is also subjected to downward pressure. The second driving member 43 abuts against the fourth molding block 42, providing upward support to the fourth molding block 42, preventing the second module 40 from being compressed and sliding along the slide rail 20 toward the molding cavity 11, thus preventing the flat wire from being pressed into a V-shape. That is to say, the second driving member 43 provides a fulcrum for the fourth molding block 42, supporting the second module 40 during the pressing of the V-shaped flat wire, ensuring the flat wire is formed. After the first module 30 and the second module 40 press the flat wire into a V-shape, the second driving member 43 leaves the fourth molding module, and the first driving member 33 drives the first module 30 to slide along the slide rail 20, causing the second module 40 to slide synchronously along the slide rail 20. In one embodiment, the second driving member 43 may also always abut against the bottom of the fourth molding block 42, and the second driving member 43 and the first driving member 33 synchronously drive the sliding of the second module 40 and the first module 30.

[0065] In this embodiment, the third forming block 41 and the second forming block 32 are connected by an elastic element. When the first module 30 and the second module 40 compress the flat wire, the elastic element provides a buffer for the first module 30 to avoid the first module 30 moving too fast and forming too much compressive force on the flat wire, which would damage the flat wire.

[0066] In one implementation, such as Figure 8 As shown, the third module 70 includes: a fifth forming block 71, a sixth forming block 72, and a third driving member 73; the fifth forming block 71 has a second snap-fit ​​platform 711 on its end face; the sixth forming block 72 has a third end face 721; the end of the third end face 721 extends outward to form a second arc-shaped platform 722; the second arc-shaped platform 722 is adapted to the first arc-shaped platform 322 for pressing the flat wire into a 3D shape; the third driving member 73 is disposed on the main body 10 and is connected to the fifth forming block 71 in a transmission manner.

[0067] Specifically, the third end face 721 engages with the second snap-fit ​​platform 711, thus fixing the fifth forming block 71 and the sixth forming block 72 together. The side of the third end face 721 facing away from the second forming block 32 extends outward to form a second arc-shaped platform 722, the shape of which matches the shape of the first arc-shaped platform 322. When the first module 30 and the second module 40 bend the flat wire into a V-shape, the first driving member 33 drives the first module 30 and the second module 40 to simultaneously slide into the forming cavity 11. When the first module 30 slides to the same horizontal line as the third module 70, the third driving member 73 drives the fifth forming block 71 to move along the x-axis, causing the sixth forming block 72 to move synchronously. The second arc-shaped platform 722 on the sixth forming block 72 embeds between the first module 30 and the second module 40, and presses against the first arc-shaped platform 322 to press the flat wire into a 3D shape.

[0068] In this embodiment, as Figure 4 and Figure 5 As shown, the first arc-shaped platform 322 includes: a first bending portion 3221, a first straight portion 3222, and a first transition portion 3223; the cross-sectional shape of the first bending portion 3221 is wave-shaped; the first straight portion 3222 is disposed opposite to each other on both sides of the first bending portion 3221; the two ends of the first transition portion 3223 are respectively connected to the first bending portion 3221 and the first straight portion 3222; the height of the first transition portion 3223 gradually decreases from the end near the first straight portion 3222 toward the end near the first bending portion 3221.

[0069] like Figure 8As shown, the second arc-shaped platform 722 includes: a second bending portion 7221, a second straight portion 7222, and a second transition portion 7223; the cross-sectional shape of the second bending portion 7221 is wave-shaped, and the second bending portion 7221 is adapted to the first bending portion 3221; the second straight portion 7222 is disposed opposite to each other on both sides of the first bending portion 3221; the two ends of the second transition portion 7223 are respectively connected to the second bending portion 7221 and the second straight portion 7222; the height of the second transition portion 7223 gradually increases from the two ends near the second straight portion 7222 toward the end near the first bending portion 3221.

[0070] Specifically, one end of the first arc-shaped platform 322 has a first bend 3221 with a wave-shaped cross-section; the first straight section 3222 is disposed opposite to the two sides of the first bend 3221, and the first straight section 3222 is inclined toward the side closer to the groove 323. When the first molding block 31 is embedded in the second molding block 32, the outer wall of the flange 3121 is tightly fitted with the inner wall of the groove 323, and a small angle is formed between the inclined surface at the top of the flange 3121 and the first straight section 3222; the first bend 3221 and the first straight section 3222 are connected by the first transition section 3223. At the same time, the height of the first transition section 3223 gradually decreases from the end closer to the first straight section 3222 toward the end closer to the first bend 3221. In other words, the first transition section 3223 presents a slope as a whole.

[0071] Similarly, one end of the second arc-shaped platform 722 is formed with a second bend 7221, and the cross-sectional shape is wave-shaped. The second bend 7221 is adapted to the first bend 3221. The second straight section 7222 is disposed opposite to the two sides of the second bend 7221, and the second straight section 7222 is inclined toward the side away from the groove 323. That is, the cross-section of the second straight section 7222 is adapted to the cross-section of the first straight section 3222. With this design, when the flat wire is located at the small angle formed between the inclined surface at the top of the flange 3121 and the first straight section 3222, it is ensured that the second straight section 7222 can fit tightly with both ends of the flat wire to accurately press the flat wire into the target shape. The second bend 7221 and the second straight section 7222 are connected by the second transition section 7223. At the same time, the height of the second transition section 7223 gradually increases from the end near the second straight section 7222 toward the end near the second bend 7221. In other words, the second transition section 7223 presents a slope as a whole. The second bend 7221 is adapted to the first bend 3221, and the second transition section 7223 is adapted to the first transition section 3223. With this design, when the flat line is located between the first straight section 3222 and the first transition section 3223, it is ensured that the second straight section 7222 and the second transition section 7223 can fit tightly with the middle of the flat line.

[0072] like Figure 9 and Figure 10 As shown, during the pressing of the flat wire, the first module 30 and the second module 40 squeeze the flat wire into a V shape. At this time, the middle part of the flat wire is located on the first bending part 3221 and the first transition part 3223. When the first pressing table 50 and the second pressing table 60 bend the flat wire into a U shape, the two ends of the flat wire are located on the first straight part 3222. When the third module 70 is inserted between the first module 30 and the second module 40, the first bending portion 3221 and the first transition portion 3223, as well as the second bending portion 7221 and the second transition portion 7223, are all tightly fitted to the middle of the flat wire and press against each other. At the same time, the first straight portion 3222 and the second straight portion 7222 are tightly fitted to both ends of the flat wire and press against each other. In this way, the U-shaped flat wire is formed by the mutual pressing of the first arc-shaped platform 322 and the second arc-shaped platform 722. That is to say, the overall shape of the first arc-shaped platform 322 and the second arc-shaped platform 722 is adapted to each other, and the overall shape is pre-set to be a 3D flat wire. The flat wire is tightly fitted to the first arc-shaped platform 322 and the second arc-shaped platform 722 by the mutual pressing of the first arc-shaped platform 322 and the second arc-shaped platform 722, and finally a 3D flat wire is formed.

[0073] In actual production, the first arc-shaped platform 322 and the second arc-shaped platform 722 can be adapted to different shapes according to the production process to meet the forming requirements of different flat wires.

[0080] S2. Start the second module 40. The first module 30 and the second module 40 slide towards the molding cavity 11 simultaneously. The first pressure table 50 and the second pressure table 60 contact the two ends of the V-shaped flat wire until the two ends of the V-shaped flat wire are bent into a U-shape.

[0081] S3. Start the third module 70. The third module 70 moves along the x direction and is inserted between the first module 30 and the second module 40 until the U-shape is squeezed into a 3D shape.

[0082] Specifically, in the initial state, the first module 30 is located outside the molding cavity 11, and the second module 40 is located at the port of the molding cavity 11. A flat wire is placed between the first module 30 and the second module 40. The first module 30 is activated, sliding along the slide rail 20 towards the second module 40 until the first module 30 and the second module 40 compress the flat wire into a V-shape. At this point, the middle of the flat wire is tightly fitted with the first V-shaped surface 311 and the second V-shaped surface 421. The first V-shaped surface 311 and the second V-shaped surface 421 mutually clamp and compress the middle of the flat wire, bending the straight flat wire into a V-shape. Subsequently, the first module... The first module 30 and the second module 40 slide into the molding cavity 11 simultaneously. During this process, the first pressure table 50 and the second pressure table 60 contact the two ends of the flat wire and bend the two ends of the flat wire into a U-shape. When the first module 30 slides to be in the same straight line as the third module 70, the third module 70 moves along the x-axis. The second arc-shaped platform 722 is inserted between the first module 30 and the second module 40, and the second arc-shaped platform 722 and the first arc-shaped platform 322 squeeze the flat wire against each other, squeezing the U-shaped flat wire to support the 3D shape.

[0083] In this embodiment, the first V-shaped surface 311 and the second V-shaped surface 421 are adapted to bend the flat wire into a V-shape, and then the first pressing table 50 and the second pressing table 60 are used to bend the V-shaped flat wire into a U-shape. Finally, the adapted first arc-shaped table 322 and the second arc-shaped table 722 are used to bend the U-shaped flat wire into a 3D shape.

[0084] In summary, this invention discloses a flat wire forming device and a forming method.

The first module and the second module are slidably disposed on the slide rail. The first module has a first V-shaped surface. The second module has a second V-shaped surface. The second V-shaped surface is adapted to the first V-shaped surface for extruding the flat wire into a V-shape. The first and second pressing platforms are disposed opposite each other at the top of the forming cavity; the first and second modules slide along the slide rail into the forming cavity, and the first and second pressing platforms abut against the two ends of the flat wire to bend the V-shaped flat wire into a U-shape; the third module is slidably disposed on the main body along the x-axis and located in the forming cavity; the third module includes a forming push plate; the forming push plate extends outward to form a first curved surface; the first curved surface is used to insert between the first and second modules to press the U-shaped flat wire into the target shape.

[0085] In use, the flat wire is placed between the first module and the second module. The first module slides toward the second module, and the flat wire is squeezed into a V-shape using the first V-shaped surface and the second V-shaped surface. Then, the first module and the second module slide into the forming cavity simultaneously. During this process, the first pressure plate and the second pressure plate located at the top of the forming cavity contact the two sides of the flat wire and bend it into a U-shape. Finally, the third module moves along the x-direction and inserts between the first module and the second module to press the U-shaped flat wire into a 3D shape. The flat wire is formed in one piece by the three modules, which improves the efficiency of flat wire forming.
