[0032] With reference to Figure 1 The wave winding automatic forming machine 1000 provided by the embodiment comprises a rack 1001, a first forming device 100 and a second forming device 200. The rack 1001 has a first direction D1 and a second direction D2 perpendicular to each other. A plane formed by the first direction D1 and the second direction D2 is parallel to the bottom surface of the rack 1001. The first forming device 100 and the second forming device 200 are respectively supported on the rack 1001. The second forming device 200 is located below the first forming device 100.

[0033] The first forming device 100 comprises a first support frame 11, a first guide rail 12, a first bending forming assembly 13 and a first spacing adjustment device 14. The first support frame 11 is installed on and supported by the rack 1001. The first guide rail 12 is not limited to two in number. The two first guide rails 12 are arranged along a direction perpendicular to the bottom surface of the rack 1001 (the upward and downward direction shown in the figure). Each first guide rail 12 extends along the first direction D1 (i.e. extends along a direction parallel to the first direction D1, hereinafter referred to as extending along the first direction D1). The first bending forming assembly 13 is movably installed on the first guide rail 12.

The two second guide rails 22 are arranged along a direction perpendicular to the bottom surface of the rack 1001 (the upward and downward direction shown in the figure). Each second guide rail 22 extends along the first direction D1. The second bending forming assembly 23 is movably installed on the second guide rail 22. The second spacing adjustment device 24 is supported on the second support frame 21 and can synchronously move a plurality of second bending forming assemblies 23 relative to the second guide rail 22. The plurality of first bending forming assemblies 13 and the plurality of second bending forming assemblies 23 are alternately arranged along the first direction D1. The projections of the first bending forming assemblies 13 and the second bending forming assemblies 23 on the side wall of the rack 1001 overlap, i.e. the first bending forming assemblies 13 in the first forming device 100 and the second bending forming assemblies 23 in the second forming device 200 intersect in the direction perpendicular to the bottom surface of the rack 1001 (the upward and downward direction shown in the figure).

[0034] With reference to Figure 17The flat wire 90 provided by the embodiment is in a straight shape and is fed into the wave winding automatic forming machine 1000, and is formed into a wave shape (S shape) after the forming of the first bending forming assembly 13 of the first forming device 100 and the second bending forming assembly 23 of the second forming device 200. It is worth mentioning that the first bending forming assembly 13 in the first forming device 100 forms the bending part 90a on the same side of the flat wire 90 (the flat wire 90 is supported in a vertical state on the wave winding automatic forming machine 1000, and the bending part on the side is located at the bottom of the flat wire 90, also known as the lower bending part or lower roof), and the second bending forming assembly 23 in the second forming device 200 forms the bending part 90b on the other side of the flat wire 90 (the bending part on the side is located at the top of the flat wire 90, also known as the upper bending part or upper roof), and the part of the flat wire 90 between the first forming device 100 and the second forming device 200 forms a straight part 90c connecting the two bending parts 90a and 90b.

[0035] Figure 2 and Figure 3 The work position schematic diagrams of the mechanisms of the first forming device 100 and the second forming device 200 in the forming process are shown respectively.

[0036] Please refer to Figure 2 and Figure 3 In the embodiment, the punching die closing directions of the first bending forming assembly 13 and the second bending forming assembly 23 are perpendicular to the bottom surface of the rack 1001 (the upward and downward directions shown in the figure), and under the control of the first spacing adjusting device 14, the first bending forming assembly 13 in the first forming device 100 can be synchronously moved on the first guide rail 12 to realize the unfolding and folding actions between the multiple first bending forming assemblies 13. Under the control of the second spacing adjusting device 24, the second bending forming assembly 23 in the second forming device 200 can be synchronously moved on the second guide rail 22 to realize the unfolding and folding actions between the multiple second bending forming assemblies 23. In this way, under the control of the first spacing adjusting device 14 and the second spacing adjusting device 24, after the multiple first bending forming assemblies 13 are moved away from each other to the unfolded position at the maximum spacing and the multiple second bending forming assemblies 23 are moved away from each other to the unfolded position at the maximum spacing, the feeding and discharging operations are performed, that is, the formed flat wire 90 is taken out and the flat wire 90 to be formed is put in. After the new flat wire 90 is put in, the first spacing adjusting device 14 and the second spacing adjusting device 24 control the multiple first bending forming assemblies 13 to move towards each other to the folded position at the minimum spacing and the multiple second bending forming assemblies 23 to move towards each other to the folded position at the minimum spacing, and at the same time, each first bending forming assembly 13 and each second bending forming assembly 23 are closed to form the flat wire 90.

[0037] See Figures 1 to 4In the embodiment, the number of the first bending forming assemblies 13 in the first forming device 100 is, but not limited to, eight, and the eight first bending forming assemblies 13 are arranged side by side in the first direction D1. The number of the second bending forming assemblies 23 in the second forming device 200 is, but not limited to, nine, and the nine second bending forming assemblies 23 are arranged side by side in the first direction D1. The first bending forming assemblies 13 and the second bending forming assemblies 23 are alternately arranged along the first direction D1.

[0038] From Figure 3 and Figure 4 it can be seen that, in the embodiment, each of the first bending forming assemblies 13 and each of the second bending forming assemblies 23 has a stamping space 10a for bending the flat wire 90. The stamping spaces 10a of the plurality of first bending forming assemblies 13 and the stamping spaces 10a of the plurality of second bending forming assemblies 23 are sequentially communicated and form a forming channel P for the flat wire 90 to be put in and taken out. Under the control of the first pitch adjusting device 14 and the second pitch adjusting device 24, the first bending forming assemblies 13 and the second bending forming assemblies 23 move relative to each other to stretch and shorten the forming channel P. After the first bending forming assemblies 13 and the second bending forming assemblies 23 are closed, the flat wire 90 in the forming channel P can be formed.

[0039] Referring to Figures 4 to 6 , the structure of the first pitch adjusting device 14 and the second pitch adjusting device 24 can be the same or different. In the embodiment, the structure of the first pitch adjusting device 14 and the second pitch adjusting device 24 is basically the same.

[0041] In the embodiment, each link assembly 142 of the first distance adjusting device 14 comprises a control rod 1421 extending in a direction perpendicular to the bottom surface of the rack 1001 (the upward and downward direction shown in the figure, which is also the mold opening direction), and a swing rod 1422, the number of which is not limited to two pairs, and the two pairs of swing rods 1422 are spaced apart in a direction perpendicular to the bottom surface of the rack 1001 (the upward and downward direction shown in the figure, which is also the mold opening direction), one end (inner end) of each swing rod 1422 in each pair is hingedly connected to the other swing rod 1422 in the pair, and the other end (outer end) is rotatably connected to the adjacent two first bending forming assemblies 13. The first support frame 11 is provided with an upper inclined guide rail 15 in a first inclined direction T1 intersecting the first direction D1, the driving mounting plate 141 of the first distance adjusting device 14 is movably mounted on the upper inclined guide rail 15, the mounting plate driving mechanism 143 of the first distance adjusting device 14 is supported on the first support frame 11, the mounting plate driving mechanism 143 is not limited to a motor-screw driving mechanism, and the mounting plate driving mechanism 143 can move the driving mounting plate 141 relative to the first support frame 11 in the first inclined direction T1, and the upper end (the upper end shown in the figure) of the control rod 1421 is connected to the driving mounting plate 141 and can move relative to the driving mounting plate 141 in the first direction D1; each link assembly 142 of the first distance adjusting device 14 is connected to the adjacent two first bending forming assemblies 13, and the outer end of the swing rod 1422 of the link assembly 142 is rotatably connected to the adjacent two first bending forming assemblies 13. It is easy to understand that under the driving of the mounting plate driving mechanism 143 of the first distance adjusting device 14, the driving mounting plate 141 of the first distance adjusting device 14 moves up and down relative to the first support frame 11 in the first inclined direction T1 and drives the control rod 1421 of each link assembly 142 to move up and down together, and the control rod 1421 moves relative to the driving mounting plate 141 in the first direction D1, and the displacement of the control rod 1421 drives the swing rod 1422 in the link assembly 142 to rotate, thereby driving the first bending forming assembly 13 to move relative to the first support frame 11 in the first direction D1, so as to realize the synchronous unfolding and folding of the plurality of first bending forming assemblies 13 on the first guide rail 12.

[0042] In the embodiment, each of the link assemblies 142 of the second distance adjusting device 24 comprises a control rod 1421 extending in a direction perpendicular to the bottom surface of the rack 1001 (the upward and downward direction shown in the figure, which is also the mold opening direction), and a swing rod 1422, the number of which is not limited to two pairs, the two pairs of swing rods 1422 being spaced apart in the direction perpendicular to the bottom surface of the rack 1001 (the upward and downward direction shown in the figure, which is also the mold opening direction), one end (the inner end) of each of the two swing rods 1422 in each pair being hingedly connected to each other, and the other end (the outer end) being rotatably connected to the adjacent two second bending forming assemblies 23. The second support frame 21 is provided with a lower inclined guide rail 25 in a second inclined direction T2 intersecting the first direction D1, the second inclined direction T2 being symmetrically arranged with the first inclined direction T1 in the first direction D1, the driving mounting plate 141 of the second distance adjusting device 24 being movably mounted on the lower inclined guide rail 25, the mounting plate driving mechanism 143 of the second distance adjusting device 24 being supported on the second support frame 21, the mounting plate driving mechanism 143 being, but not limited to, a motor-screw driving mechanism, the mounting plate driving mechanism 143 being capable of moving the driving mounting plate 141 relative to the second support frame 21 along the second inclined direction T2, the upper end (the upper end shown in the figure) of the control rod 1421 being connected to the driving mounting plate 141 and being movable relative to the driving mounting plate 141 along the first direction D1; each of the link assemblies 142 of the second distance adjusting device 24 is connected to the adjacent two second bending forming assemblies 23, the adjacent two second bending forming assemblies 23 being rotatably connected to the outer end of the swing rod 1422 of the link assembly 142. It is easy to understand that, under the driving of the mounting plate driving mechanism 143 of the second distance adjusting device 24, the driving mounting plate 141 of the second distance adjusting device 24 moves up and down relative to the second support frame 21 along the second inclined direction T2 and drives the control rod 1421 of each link assembly 142 to move up and down together, and the control rod 1421 moves relative to the driving mounting plate 141 along the first direction D1, the control rod 1421 being capable of driving the swing rod 1422 in the link assembly 142 to rotate while being displaced, thereby driving the second bending forming assembly 23 to move relative to the second support frame 21 along the first direction D1, so as to realize the synchronous unfolding and folding of the plurality of second bending forming assemblies 23 on the second guide rail 22.

[0043] Referring to Figures 4 to 10The first bending forming assembly 13 and the second bending forming assembly 23 provided by the embodiment both include a bearing plate 131, a hinged seat 132, an assembly seat 133, a male die 134, a female die 135 and a stamping driving mechanism 136.

It should be noted that one of the first bending forming assemblies 13 can also be fixed, and the other first bending forming assemblies 13 can move relative to the fixed first bending forming assembly 13.

[0049] See Figures 6 to 10 , Figure 17 In this embodiment, the die 135 of the first bending forming component 13 has a stamping groove 135a, which is located on the side surface of the die 135 facing the punch 134 corresponding to the die 135 and is recessed in a direction away from the punch 134. The stamping groove 135a includes an arc-shaped recessed portion 1351 located in the middle of the surface of the die 135, and two inclined walls 1352 extending obliquely from both sides of the recessed portion 1351 toward the edge of the surface of the die 135. The punch 134 has a stamping head 1341 that matches the stamping groove 135a. The surface of the stamping head 1341 is formed with a plurality of receiving grooves 134a for the flat wire 90 to be inserted. The plurality of receiving grooves 134a are arranged along the second direction D2 (i.e., the direction perpendicular to the surface of the support plate 131). The upper forming die 161 of the third bending forming component 16 includes a stamping notch 161a. The stamping notch 161a extends from the center of the bottom surface of the upper forming die 161 towards the side surface of another upper forming die 161. The shape of the lower forming die 162 matches the stamping notch 161a. It should be noted that the shape of the lower forming die 162 is approximately the shape of the die 135 after being cut along its centerline. During the forming process, after the first bending forming component 13, the second bending forming component 23, and the third bending forming component 16 are closed, the position of the lower forming die 162 of the third bending forming component 16 corresponds to the position of the die 135 of the first bending forming component 13. That is, the bottom surface of the lower forming die 162 of the third bending forming component 16 is flush with the bottom surface of the die 135 of the first bending forming component 13.

The pressing device 300 comprises a pressing mounting seat 310, a pressing driving mechanism (not shown in the figure) and a pressing block 320. The pressing mounting seat 310 is movably mounted on the rack 1001 along a first direction D1. The pressing driving mechanism is used to move the pressing mounting seat 310 along the first direction D1. The pressing block 320 is used to abut against the outside of the third bending forming assembly 16 movably mounted on the first guide rail 12 among the two third bending forming assemblies 16. The pressing block 320 is movably mounted on the pressing mounting seat 310 along a second direction D2. In the embodiment, the pressing driving mechanism is but not limited to a motor-screw mechanism. The pressing driving mechanism is connected with the pressing mounting seat 310 and can drive the pressing mounting seat 310 to move along the first direction D1. The pressing block 320 is mounted on the pressing mounting seat 310. The bottom of the pressing block 320 is provided with a driving member (not shown in the figure) to move the pressing block 320 relative to the pressing mounting seat 310 along the second direction D2, so as to realize the extension and retraction of the pressing block 320 on the pressing mounting seat 310. It can be understood that, after the first bending forming assembly 13 and the movable third bending forming assembly 16 are folded towards the fixed third bending forming assembly 16, the pressing driving mechanism drives the pressing mounting seat 310 to move the pressing block 320 towards the fixed third bending forming assembly 16 and abut against the movable third bending forming assembly 16. When the first bending forming assembly 13 and the movable third bending forming assembly 16 move away from the fixed third bending forming assembly 16, the pressing block 320 is retracted to avoid interference with the first bending forming assembly 13 and the third bending forming assembly 16. Under the driving of the pressing driving mechanism, the pressing mounting seat 310 is reset and moves. In this way, the first bending forming assembly 13, the second bending forming assembly 23 and the third bending forming assembly 16 can be pressed tightly by using the pressing device 300, so as to eliminate the gap of the bending forming assemblies and improve the forming quality.

The first pulling device 410 and the second pulling device 420 are both installed on a flattening support frame (which can also be directly installed on the rack 1001) not shown in the figure and are arranged in a first direction D1. The first pulling device 410 includes a first pulling base 411 located in the middle of the rack 1001, a first wire loading table 412, a first wire pressing mechanism 413 and a first pulling driving mechanism 414. The first wire loading table 412 is arranged on the first pulling base 411, and a first wire groove 4121 extending in the first direction D1 is formed on the surface of the first wire loading table 412 for placing the end of the flat wire 90. The first wire pressing mechanism 413 is arranged on the first pulling base 411 and used for pressing the end of the flat wire 90 on the first wire loading table 412.

The second pulling device 420 includes a second pulling base 421, a second wire loading table 422, a second wire pressing mechanism 423 and a second pulling driving mechanism 424. The second pulling base 421 is arranged in parallel with and spaced apart from the first pulling base 411 in the first direction D1. The second wire loading table 422 is arranged on the second pulling base 421, and a second wire groove 4221 extending in the first direction D1 is formed on the surface of the second wire loading table 422 for placing the end of the flat wire 90. The second wire pressing mechanism 423 is arranged on the second pulling base 421 and used for pressing the end of the flat wire 90 on the second wire loading table 422. The second pulling driving mechanism 424 is connected with the second pulling base 421 and used for moving the second pulling base 421 in the first direction D1. The second wire pressing mechanism 423 includes a contact block 425 made of a non-metal material and used for contacting the flat wire 90.

[0054] In this embodiment, a leveling support frame (not shown) is provided with a first leveling guide rail 43, which extends along a first direction D1. A first traction base 411 is movably mounted on the first leveling guide rail 43. A first wire carrier 412 and a first wire pressing mechanism 413 are respectively supported on the first traction base 411. A first traction drive mechanism 414 is, but is not limited to, a motor screw drive mechanism. The first traction drive mechanism 414 is supported on the leveling support frame and connected to the first traction base 411. The line leveling device 400 also includes a traction base 44, which is arranged side by side and spaced apart from the first traction base 411 along the first direction D1. A second leveling guide rail 45 extending along the first direction D1 is provided on the traction base 44. A second traction base 421 is movably mounted on the second leveling guide rail 45. A second wire carrier 422 and a second wire pressing mechanism 423 are respectively supported on the second traction base. On seat 421; thus, after the flat wire 90 is moved into the line leveling device 400, one end of the flat wire 90 is placed in the first wire groove 4121 of the first wire carrier 412, and the other end of the flat wire 90 is placed in the second wire groove 4221 of the second wire carrier 422. The first pressing mechanism 413 and the second pressing mechanism 423 are controlled to press the two ends of the flat wire 90 onto the first wire carrier 412 and the second wire carrier 422 respectively. Then, the first pulling drive mechanism 414 and the second pulling drive mechanism 424 move the first pulling base 411 and the second pulling base 421 in opposite directions, thereby flattening the flat wire 90. In this way, since the second pressing mechanism 423 uses a non-metallic contact block 425 to contact the flat wire 90, relative displacement can be generated between the contact block 425 and the flat wire 90 during the flattening process, which can avoid the paint wear of the flat wire 90 during the pulling process, thereby ensuring product quality. It should be noted that during leveling, the first pulling drive mechanism 414 is the main driving source for pulling. That is, after the flat wire 90 is fed into the first pulling device 410 and the second pulling device 420, the first pulling base 411 is approximately located at the right end of the first leveling guide rail 43 (the right end in the figure), and the second pulling base 421 is also located at the right end of the second leveling guide rail 45 (the right end in the figure). After the first pressing mechanism 413, the first wire carrier 412, the second pressing mechanism 423, and the second wire carrier 422 clamp the two ends of the flat wire 90 respectively, the first pulling base 411 moves to the left (the left direction in the figure) under the drive of the first pulling drive mechanism 414, thereby leveling the flat wire 90.

[0055] See Figure 11 , Figure 14 , Figure 15In the embodiment, the first wire slot 4121 on the first wire carrier 412 is in a plurality, and the plurality of first wire slots 4121 are arranged along the second direction D2; the second wire slot 4221 on the second wire carrier 422 is in a plurality, and the plurality of second wire slots 4221 are arranged along the second direction D2.

[0056] Referring to Figures 11 to 13 The first wire pressing mechanism 413 comprises a punch mounting seat 4131, a wire pressing punch 4132 for pressing the end of the flat wire 90 on the first wire carrier 412, and a punch driving assembly 4133 for driving the wire pressing punch 4132 to move up and down; the punch mounting seat 4131 is mounted on the first pulling base 411, the wire pressing punch 4132 is movably arranged on the punch mounting seat 4131 and above the first wire carrier 412; the punch driving assembly 4133 comprises a punch power member 41331 and a punch connecting rod 41332 rotatably mounted on the punch mounting seat 4131, one end of the punch connecting rod 41332 is hinged to the wire pressing punch 4132, the other end is hinged to the punch power member 41331, and the punch power member 41331 is rotatably mounted on the first pulling base 411.

The punch driving assembly 4133 comprises the punch power member 41331 and the punch connecting rod 41332, the middle part of the punch connecting rod 41332 is hinged to the top of the punch mounting seat 4131, both ends of the punch connecting rod 41332 are hinged to the top end of the punch power member 41331 and the wire pressing punch 4132 respectively, and the punch power member 41331 is rotatably mounted on the first pulling base 411. The punch power member 41331 is a gas cylinder, but is not limited to this. It can be understood that the extension and retraction of the output shaft of the punch power member 41331 can drive the punch connecting rod 41332 to swing and make the wire pressing punch 4132 move up and down. Therefore, after the end of the flat wire 90 is placed on the first wire carrier 412, the punch power member 41331 drives the wire pressing punch 4132 to descend to the first wire carrier 412, so as to press the flat wire 90 on the first wire carrier 412.

[0057] Referring to Figure 13The punch mounting base 4131 has a punch sliding groove 41311 for the wire pressing punch 4132 to slide, and the two ends of the wire pressing punch 4132 extend out of the punch sliding groove 41311. In this embodiment, the punch sliding groove 41311 is located above the first wire loading table 412, extends in a direction perpendicular to the surface of the first pulling base 411, and penetrates the surface of the punch mounting base 4131 at both ends. In this way, the wire pressing punch 4132 is mounted by forming the punch sliding groove 41311 on the punch mounting base 4131, which can ensure that the wire pressing punch 4132 moves more smoothly and improve the wire pressing effect.

[0058] Referring to Figure 13 In this embodiment, the bottom end of the wire pressing punch 4132 is provided with a plurality of tooth portions 4132a for contacting the flat wire 90, and the plurality of tooth portions 4132a are arranged along the first direction D1. In this way, the plurality of tooth portions 4132a are formed on the bottom end of the wire pressing punch 4132, which can prevent the flat wire 90 from sliding after being pressed.

[0059] Referring to Figures 11 to 13 In this embodiment, the first pulling base 411 is provided with an end flattening block 415 for abutting against the end face of the flat wire 90 and a flattening power member 416 for driving the end flattening block 415 to move along the first direction D1, and the punch mounting base 4131 is provided with a flattening groove 41312 for the end flattening block 415 to move. In this embodiment, the flattening power member 416 is a pneumatic cylinder, but is not limited thereto. The flattening power member 416 is fixedly installed on the first pulling base 411 and located on the side of the first wire loading table 412 away from the second wire loading table 422. The end flattening block 415 is located between the first wire loading table 412 and the flattening power member 416 and is fixedly installed on the output shaft of the flattening power member 416. The side of the end flattening block 415 facing the first wire loading table 412 has a flat surface perpendicular to the surface of the first pulling base 411. In this way, after the flat wire 90 is placed, the flattening power member 416 drives the end flattening block 415 to move along the first direction D1 and abuts against the end of the flat wire 90, so as to push the flat wire 90 to a predetermined position, or abuts against the ends of a plurality of flat wires 90 and pushes the ends of the plurality of flat wires 90 to the same plane, so as to make the ends of the flat wires 90 flush.

[0060] Referring to Figure 11 , Figures 14 to 16The second line pressing mechanism 423 provided by the embodiment comprises a line pressing seat mounting support 4231, a line pressing seat 4232 for pressing the end of the flat wire 90 on the second wire loading table 422 against the second wire loading table 422, and a line pressing seat driving assembly 4233 for driving the line pressing seat 4232 to ascend and descend; the line pressing seat mounting support 4231 is mounted on the second pulling base 421, the line pressing seat 4232 is mounted on the line pressing seat mounting support 4231 in a manner that can ascend and descend, the line pressing seat driving assembly 4233 is supported on the line pressing seat mounting support 4231 and connected with the line pressing seat 4232; a contact block 425 is mounted on the bottom of the line pressing seat 4232.

In this way, the non-metallic contact block 425 is additionally arranged on the line pressing seat 4232, after the flat wire 90 is put in, the line pressing seat driving assembly 4233 drives the line pressing seat 4232 to descend, the contact block 425 abuts against the flat wire 90 and presses the flat wire 90 against the second wire loading table 422, and the first pulling driving mechanism 414 drives the first pulling base 411 to move away from the second pulling device 420 in the first direction D1 to flatten the flat wire 90. Since the contact block 425 made of non-metallic material contacts the surface of the flat wire 90, after the flat wire 90 is flattened, as the first pulling base 411 continues to move, displacement can occur between the contact block 425 and the flat wire 90, so that the paint of the flat wire 90 can be prevented from being damaged, thereby affecting the product quality.
