Description

Technical Field

[0001] This invention relates to the field of copper wire forming equipment technology, and in particular to a copper wire seamless bending forming device. Background Technology

[0002] Hairpin permanent magnet synchronous motors are gradually being widely used in the domestic drive motor market. Compared with traditional wound-rotor motors, due to the flat nature of hairpin copper wire, the motor is smaller and has higher power at the same power output, making it the next generation of new energy drive motors. In the processing of copper wire for new energy vehicle engines, a two-step forming method is typically used: first, a 2D forming structure is used to bend the straight wire, and then a 3D forming structure is used to press the bent copper wire into shape. However, in practice, the 2D forming structure cannot effectively fix the position of the copper wire during bending, easily causing damage, narrowing of the wire width, and uneven wire lengths, which is detrimental to subsequent 3D forming operations. Summary of the Invention This invention provides a copper wire seamless bending and forming device to overcome the technical problem that existing 2D forming structures easily cause copper wire to be squeezed during bending, resulting in defects such as copper wire breakage, narrowing of line width, and uneven length, which are not conducive to subsequent 3D forming operations.

The primary bending component is disposed in the receiving cavity and opposite to the second bending and forming module. The copper wire is disposed in the copper wire mounting groove and located between the primary bending component and the second bending and forming module. When it is necessary to bend the copper wire, the first driving component drives the first bending forming module to move closer to the second bending forming module. When the first bending component comes into contact with the second bending forming module, the first bending component stops moving and the copper wire is symmetrically bent to form an angle and fixed. Then the second bending component continues to move along the guide module, and the movement trajectory changes from linear movement to rotational movement, symmetrically bending the copper wire a second time and making the two legs of the copper wire parallel after bending.

[0006] Furthermore, the second bending forming module includes a base plate and a limiting block; the base plate is disposed on the first mounting plate, and the base plate is provided sequentially along the direction away from the first mounting plate for a first bending protrusion to abut against the seamless bending rotating part and a second bending protrusion to match the bending groove; the limiting block is disposed on the base plate, and when the copper wire is symmetrically bent once, the other end of the first bending plate abuts against the limiting block, and the distance between the bending groove and the second bending protrusion is the width of the copper wire.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0018] This embodiment provides a copper wire seamless bending and forming device, such as... Figures 1 to 4 As shown, it includes a 2D forming structure 1 and a 3D forming structure 2. The 2D forming structure 1 is used to bend the copper wire to form a 2D formed copper wire, and the 3D forming structure 2 is used to extrude the copper wire to form a 3D formed copper wire. The 2D forming structure 1 includes a first mounting plate 11, a first driving assembly 12, a first bending forming module 13, a second bending forming module 14, and a guide module 15. The first driving component 12 and the second bending and forming module 14 are disposed opposite each other on one side end face of the first mounting plate 11. The first driving component 12 is connected to the first bending and forming module 13. The guide module 15 is disposed at the end of the first mounting plate 11 where the second bending and forming module 14 is disposed. The first bending forming module 13 includes a primary bending component 16 and a secondary bending assembly 17. The secondary bending assembly 17 is connected to the first driving assembly 12, and the secondary bending assembly 17 is provided with a receiving cavity for accommodating the primary bending component and a copper wire mounting groove. The primary bending component 16 is disposed in the receiving cavity for accommodating the primary bending component and is opposite to the second bending forming module 14. The copper wire is disposed in the copper wire mounting groove and is located between the primary bending component 16 and the second bending forming module 14. Specifically, in this embodiment, the first driving component 12 includes a driving plate and a driving connection part disposed at one end of the driving plate. The driving connection part is used to connect to a power source. The driving plate is connected to the first bending and forming module 13. The driving plate moves the first bending and forming module 13 under the driving action of the power source. A linear slide rail is provided on the end face of the first mounting plate 11. A slider is provided on the end face of the driving plate near the linear slide rail. The driving plate and the first mounting plate 11 are slidably connected to ensure that the movement trajectory of the first bending and forming module 13 is linear.

[0019] When it is necessary to bend the copper wire, the first driving component 12 drives the first bending forming module 13 to move towards the second bending forming module 14. When the first bending component 16 comes into contact with the second bending forming module 14, it stops moving and the copper wire is symmetrically bent into an angle and fixed. Then the second bending component 17 continues to move along the guide module 15, and the movement trajectory changes from linear movement to rotational movement, symmetrically bending the copper wire a second time and making the two legs of the copper wire parallel after bending.

[0020] In a specific embodiment, such as Figure 3 As shown, the secondary bending assembly 17 includes a fixing part 171, two adjusting parts 172, and two seamless bending rotating parts 173; one end face of the first mounting plate 11 is provided with a slide rail, one end face of the fixing part 171 is connected to the first driving assembly 12, and the other end face is provided with a slider, which is slidably connected to the first mounting plate 11 through the slider; the fixing part 171 is provided with a receiving cavity for accommodating the primary bending component, the primary bending component 16 is movably disposed in the receiving cavity for accommodating the primary bending component, and one end is elastically connected to the fixing part 171, and the other end is opposite to the second bending forming module 14.

[0021] In a specific embodiment, such as Figure 5 As shown, the bending component 16 includes a connecting plate 161, a first spring, and a first bending plate 162, wherein the connecting plate 161 is connected to one end of the first bending plate 162; The connecting plate 161 has an internal groove for accommodating the first spring, and its outer wall has corresponding retaining posts, such as... Figure 3 As shown, the fixing part 171 includes a cover plate 171A and a fixing frame 171B. The cover plate 171A is disposed at one end of the fixing frame 171B. The inner wall of the fixing frame 171B is provided with a slot that matches the locking post. The connecting plate 161 is movably connected to the fixing frame 171B through the locking post.

[0022] Specifically, the first spring (not shown in the figure) is disposed in the groove for accommodating the first spring, with one end abutting against the connecting plate 161 and the other end abutting against the cover plate 171A. Specifically, by providing the first spring between the connecting plate 161 and the cover plate 171A, it is ensured that when the 2D forming structure 1 returns, the elastic force generated by the compression of the spring during the outward stroke will push out the bending component 16, thereby ensuring the smooth bending of the copper wire in the next stroke.

[0023] like Figure 5As shown, the first bending plate 162 has an angled bending groove, and the bending groove matches one end of the second bending forming module 14. Specifically, the bending groove is a V-shaped groove structure used to bend the copper wire.

[0024] Specifically, in this embodiment, the fixing frame 171B includes a portion for accommodating a bending component 16, formed by two opposing panels and two opposing side panels. The inner wall of the fixing frame 171B is provided with a slot, and the outer wall of the bending component 16 is provided with a locking post that matches the slot. The bending component 16 is connected to the fixing frame 171B through the locking post, allowing the bending component 16 to slide along the fixing frame 171B. The fixing frame 171B also includes four adjustment part connecting plates. The adjustment part connecting plates are integral with the panels. Each pair of adjustment part connecting plates is arranged opposite each other to form a receiving cavity for accommodating the adjustment part. The adjustment part 172 is disposed in the receiving cavity for accommodating the adjustment part through a second rotating shaft.

[0025] Specifically, each of the seamless bending rotating parts 173 is movably connected to each of the adjusting parts 172, and each seamless bending rotating part 173 is provided with a groove of the same width as the copper wire. When the copper wire is bent for the second time by the secondary bending assembly 17, each of the adjusting parts 172 slides along the guide module 15, so that the seamless bending rotating part 173 abuts against the second bending forming module 14. The seamless bending rotating part 173 rotates about the point of abutment against the second bending forming module 14 as an axis, and the two ends of the copper wire are bent towards each other through the groove of the same width as the copper wire.

[0026] In a specific embodiment, the second bending forming module 14 includes a base plate 141 and a limiting block 142; The base plate 141 is disposed on the first mounting plate 11. The base plate is provided with a first bending protrusion 143 for abutting against the seamless bending rotation part 173 and a second bending protrusion 144 for matching the bending groove part along the direction away from the first mounting plate 11.

[0027] Specifically, such as Figure 6As shown, the base plate 141 is an integral structure composed of a V-shaped structural plate and a square plate. A first bending protrusion 143 and a second bending protrusion 144 are machined on the V-shaped structural plate. The first bending protrusion 143 is a machined arc structure, i.e., an R-angle. This arc structure can provide a fulcrum for the seamless bending rotating part 173, so that the seamless bending rotating part 173 rotates around the fulcrum that abuts against the arc structure. The R-angle serves as a reference for the bending rotation of the copper wire, so that the center of the bend after the copper wire is bent is the same as the center of the R-angle. The second bending protrusion 144 includes a V-shaped protrusion corresponding to the bending groove and an arc structure. The V-shaped protrusion is used to cooperate with the bending groove to bend and fix the copper wire once. The arc structure in the second bending protrusion 144 is used to give way to the copper wire during the second bending of the copper wire, ensuring that the copper wire can bend inward smoothly.

[0028] like Figure 6 As shown, the limiting block 142 is disposed on the base plate 141. When the copper wire is symmetrically bent once, the other end of the first bending plate 162 abuts against the limiting block 142, and the distance between the bending groove and the second bending protrusion 144 is the width of the copper wire, ensuring that the copper wire is fixed without being squeezed or damaged.

[0029] In a specific embodiment, such as Figure 3 As shown, the guiding module 15 includes two linear guide rails 151 and two adjusting guide rails 152. The two linear guide rails 151 are arranged opposite to each other on the first mounting plate 11. One end of each adjusting guide rail 152 is connected to the linear guide rail 151 through a first rotating shaft, and the other end is provided with an adjusting elongated hole. The adjusting guide rail 152 is fixedly connected to the first mounting plate 11 by passing a screw through the adjusting elongated hole. Specifically, the linear guide rail is a rectangular structure and is fixed to the first mounting plate 11 by screws. The adjusting structure is a rectangular structure and is connected to the linear guide rail 151 through a concave-convex structure and then through the first rotating shaft. If the copper wire expands outward after bending, the position of the adjusting guide rail 152 can be adjusted to rotate the adjusting guide rail closer to the copper wire and fix it. This allows the secondary bending assembly 17 to further bend the copper wire inward along the guide rail when bending it for the second time, thereby further bending the copper wire inward and avoiding the problem of the copper wire expanding outward.

[0030] like Figure 1 As shown, the two adjustment parts 172 are disposed opposite each other at one end of the fixing part near the second bending and forming module 14, and are located on both sides of the second bending and forming module 14. One end of each adjustment part 172 elastically abuts against the side wall of the fixing part 171, and the other end abuts against the guide module 15; specifically, as shown... Figure 7As shown, each of the adjustment parts 172 includes an adjustment frame 172A, a second spring, and a guide wheel 172B. The adjustment frame 172A is connected to the fixed frame 171B via a second rotating shaft. The side wall of the adjustment frame 172A away from the first bending component 16 is provided with a groove for accommodating the second spring. The second spring (not shown in the figure) is disposed in the groove for accommodating the second spring, and one end abuts against the adjustment frame 172A, while the other end abuts against the baffle A disposed on the side wall of the fixed frame 171B.

[0031] Specifically, the adjustment frame 172A is further provided with a groove for accommodating the guide wheel. The guide wheel 172B is installed in the groove for accommodating the guide wheel and is kept in contact with the guide module 15 under the elastic force of the second spring. The adjustment frame 172A is also provided with a groove for accommodating the non-marking bending rotating part, and the groove for accommodating the non-marking bending rotating part is positioned opposite to the groove for accommodating the guide wheel.

[0032] Specifically, in this embodiment, the adjustment frame 172A is connected to the fixed frame 171B via the second rotating shaft, so that one end of the adjustment frame 172A abuts against the baffle A on the side wall of the fixed frame 171B via the second spring. The elastic force of the second spring causes the guide wheel 172B located at the other end of the adjustment frame 172A to always abut against the guide module 15 during the movement, so that the adjustment part 172 can move along the guide module 15 under the driving action. Furthermore, the force generated by the adjustment part 172 on the seamless bending rotating part 173 ensures that the seamless bending rotating part 173 can smoothly bend the copper wire after it abuts against the second bending forming module 14.

[0033] Specifically, in this embodiment, such as Figure 7 As shown, each of the seamless bending rotating parts 173 includes a seamless bending rotating block 173A and a reset torsion spring 173B. The seamless bending rotating block 173A is disposed in a groove for accommodating the seamless bending rotating part and is connected to the adjustment frame 172A via a third rotating shaft. The reset torsion spring 173B is disposed on one end face of the adjustment frame, with one end abutting against the outer wall of the second rotating shaft and the other end abutting against the stop bar B disposed on the side wall of the seamless bending rotating block 173A. Specifically, during the return stroke of the 2D forming structure 1, the elastic force generated by the reset spring can reset the seamless bending rotating block 173A, thereby ensuring the smooth bending of the copper wire in the next stroke.

[0034] Specifically, in this embodiment, the seamless bending rotating block 173A includes an arc-shaped structure portion and a prism-shaped structure portion. The arc-shaped structure portion is disposed in a groove for accommodating the seamless bending rotating part and is connected to the adjustment frame 172A through a third rotating shaft. When the seamless bending rotating block 173A is not in contact with the second bending forming module 14, the straight end of the prism-shaped structure portion is always parallel to one end of the first bending protrusion 143. When the seamless bending rotating block 173A is in contact with the first bending protrusion 143, the seamless bending rotating block 173A rotates around the point in contact with the first bending protrusion 143 under the action of external force, ensuring that the seamless bending rotating block 173A can smoothly bend the copper wire a second time.

[0035] Specifically, the working process of the 2D forming structure 1 in this embodiment is as follows: When it is necessary to bend the copper wire, the first driving component 12 drives the first bending forming module 13 to move towards the second bending forming module 14. The first bending plate 162 in the first bending component 16 cooperates with the second bending protrusion in the second bending forming module 14 to bend the copper wire from the middle position into a V-shaped structure. This is the first bending of the copper wire. After the first bending, the position of the first bending component 16 is restricted by the limiting block 142 and cannot continue to move. Thus, the copper wire is fixed between the first bending component 16 and the second bending forming module 14. Then, the first driving component 12 drives the second bending component 17 to continue to move along the guide module 15. When the seamless bending rotating block 173A abuts against the first bending protrusion 143, the movement trajectory changes from linear movement to rotational movement. Through rotational movement, the two legs of the copper wire are bent towards the second bending forming module 14. This is the second symmetrical bending of the copper wire. The copper wire is 2D formed through two bending operations.

[0036] In a specific embodiment, the 2D-formed copper wire further needs to be pressed and molded by the 3D forming structure 2 to obtain the final 3D-formed copper wire, such as... Figure 8 As shown, the 3D molding structure 2 includes a second mounting plate 21, a base 22, a second driving assembly (not shown in the figure), a pressing molding assembly 24, and a copper wire position fixing assembly 25; the second mounting plate 21 is disposed on one side of the base 22, the copper wire position fixing assembly 25 is disposed on the base 22, the pressing molding assembly is connected to the second mounting plate 21 and is opposite to the copper wire position fixing assembly 25, and the end face of the pressing molding assembly away from the copper wire position fixing assembly 25 is connected to the second driving assembly; Specifically, such as Figure 9 and Figure 10As shown, the base 22 includes a first base 221 and a second base 222 disposed on the first base; the copper wire position fixing component 25 includes a first fixing component 251, two second fixing components 252 and a fifth fixing block 253; the fifth fixing block 253 is disposed in the middle position of the second base 222, the first fixing component 251 is disposed on the first base 221 and elastically connected to the second base 222; the two second fixing components 252 are disposed opposite to each other on the second base 222 and elastically connected to the second base 222.

[0037] When it is necessary to press the copper wire into shape, the second driving component drives the pressing and forming component 24 to move towards the copper wire position fixing component 25. During the movement, the pressing and forming component 24 first pushes the first fixing component 251 towards the fifth fixing block 253 to initially fix the copper wire. Then, it pushes the two second fixing components 252 towards the fifth fixing block 253 to finally determine the forming space of the copper wire and press the copper wire into shape.

[0038] Specifically, the second base 222 includes a base plate with a groove in the middle for mounting the fifth fixing block and a baffle along the groove. The fifth fixing block 253 is disposed in the groove, forming a copper wire placement area between itself and the baffle. After the copper wire is placed in this area, the end face of the copper wire is in contact with the outer wall of the fifth fixing block, and then the copper wire is fixed. In this embodiment, a second limiting plate 254 is provided above the fifth fixing block. When the second drive assembly uses an electric cylinder, the second limiting plate 254 is not required because the electric cylinder can control the movement distance more accurately. When the second drive assembly uses a pneumatic cylinder, the second limiting plate 254 is required because the pneumatic cylinder's distance control is not as precise as that of the electric cylinder, thereby limiting the position of the blade and preventing damage to the copper wire.

[0039] In a specific embodiment, such as Figure 10 As shown, the pressing and forming assembly 24 includes a fixed guide post 241, a fixed plate 242, and a pressing part 243; the end face of the second mounting plate 21 is provided with a slot, and the fixed plate 242 is matched and connected to the second mounting plate 21 through the slot and fixed with screws; one end of the fixed guide post 241 is connected to the second driving assembly, and the other end passes through the fixed plate 242 and is connected to the pressing part 243.

[0040] like Figure 9As shown, the pressing part 243 includes a first pressing plate 243A, a second pressing plate 243B, a third pressing plate 243C, a blade 243D, a first locking block 243E, and two second locking blocks 243F. The first pressing plate 243A is disposed between the fixed plate 242 and the second pressing plate 243B. The second pressing plate 243B has a notch for placing the third pressing plate 243C. The third pressing plate 243C is connected to the second pressing plate 243B through the notch. The blade 243D is disposed between the second pressing plate 243B and the third pressing plate 243C. One end of the first locking block 243E is connected to the second pressing plate 243B, and the other end has an inclined surface. The two second locking blocks 243F are disposed opposite to each other on both sides of the second pressing plate 243B, and each has an inclined surface.

[0041] Specifically, in this embodiment, one end of the first locking block 243E is fixed to the first pressure plate 243A by screws. Each second locking block 243F is provided with threaded holes that connect to the first pressure plate 243A and the second pressure plate 243B, and is connected to the first pressure plate 243A by screws. At the same time, the screws pass through the through holes provided on the second pressure plate 243B and the blade 243D to connect to the third pressure plate 243C, thereby fixing the blade 243D.

[0042] In a specific embodiment, such as Figure 11 and Figure 12As shown, the first fixing component 251 includes a first fixing block 251A, two second fixing blocks 251B, and a third spring. The first fixing block 251A is disposed on the first base 221 and has a groove for installing the third spring. The third spring is disposed in the groove for installing the third spring, with one end abutting against the first fixing block 251A and the other end abutting against the second base 222. Specifically, the first fixing block 251A includes a spring abutting portion and a V-shaped portion. The spring abutting portion has a groove for installing the third spring and... The third spring abuts against the bottom plate of the second base 222, while the V-shaped portion aligns with the baffle of the second base 222. Both shapes match the V-shaped area of ​​the copper wire. The distance between the V-shaped portion and the baffle of the second base 222 is the width of the copper wire, thus ensuring stable fixation of the copper wire. The first fixing block 251A has a groove matching the first locking block 243E at one end near the first locking block 243E. Two second fixing blocks 251B are arranged opposite each other on both sides of the first fixing block 251A and are connected to it in a concave-convex matching manner. The first fixing assembly 251 also includes a first slider 251C, which is mounted on the first base 221. The first fixing block 251A has a groove matching the first slider 251C. Specifically, the arrangement of the second fixing blocks 251B and the first slider 251C restricts the movement of the first fixing block 251A, thereby successfully fixing the copper wire.

[0043] like Figure 12 As shown, each of the second fixing components 252 includes a third fixing block 252A, two fourth fixing blocks 252B, a first limiting plate 252D, and a fourth spring (not shown in the figure). The third fixing block 252A is disposed on the second base 222 and has a groove for installing the fourth spring. The fourth spring is disposed in the groove for installing the fourth spring, with one end abutting against the third fixing block 252A and the other end abutting against the second base 222. The two fourth fixing blocks 252B are disposed opposite each other on both sides of the third fixing block 252A and are concave-convex connected to the third fixing block 252A. One end of the first limiting plate 252D is connected to the second base 222, and the other end abuts against the third fixing block 252A. The second fixing component 252 also includes a second slider 252C, which is mounted on the second base 222. The third fixing block 252A has a groove that matches the second slider 252C. Specifically, the fourth fixing block 252B and the second slider 252C can restrict the movement of the third fixing block 252A, thereby successfully fixing the copper wire. The first limiting plate 252D limits the movement range of the third fixing block 252A, ensuring smooth operation.

[0044] Specifically, such as Figure 9 As shown, the 3D molding structure 2 also includes a guide assembly 26, which includes two first guide posts and two second guide posts. The two first guide posts are installed at the end corners of the pressing molding assembly 24 near the second mounting plate 21 via guide sleeves, and the two second guide posts are installed at the end corners of the pressing molding assembly 24 away from the second mounting plate 21 via guide sleeves. One end of each first guide post is connected to the first base 221, and the other end is connected to the pressing molding assembly 24. The fixing plate 242 is provided with a groove for accommodating the mounting cap. Each second guide post is provided with a mounting cap at one end near the fixing plate 242 and is connected to the fixing plate 242 via the mounting cap. The other end of each second guide post passes through the pressing part 243. The arrangement of the first and second guide posts ensures that the movement trajectory of the pressing molding assembly 24 remains straight, thereby smoothly pressing the copper wire into shape.

[0045] Specifically, in this embodiment, the working process of the 3D forming structure 2 is as follows: When it is necessary to press the copper wire into shape, the second driving component drives the pressing forming component 24 to move towards the copper wire position fixing component 25. During the movement, the first locking block 243E gradually extends into the groove of the first fixing block 251A, thereby pushing the first fixing block 251A towards the fifth fixing block 253, so that it cooperates with the fifth fixing block 253 to initially fix the V-shaped part of the copper wire. Subsequently, the two second locking blocks 243F gradually abut against the end face of the third fixing block 252A, and push the third fixing block 252A towards the fifth fixing block 253, finally fixing the copper wire. After the copper wire is fixed, the blade continues to approach the copper wire to press the copper wire into shape. The 3D forming structure avoids the problem of easy deformation of the copper wire during the forming process by ensuring the fixation of the copper wire forming space.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
