Description

Technical Field

[0001] This invention relates to the technical field of corrugated flat wire motor manufacturing, and in particular to an automatic corrugated forming machine. Background Technology

[0002] Currently, in the field of stator windings for electric motors, flat wires are used instead of round wires for stator windings to form flat wire motors. By changing the stator cross-section and end structure, flat wire motors can accommodate more conductors under the same conditions, resulting in significantly smaller and more uniform gaps between conductors. Flat wire stator windings include the following forms: hairpin windings, i-pin windings, and flat wire continuous wave windings. Among them, flat wire continuous wave windings have the advantage of fewer solder joints compared to hairpin windings and i-pin windings, and the manufacturing process is also simpler than that of hairpin windings and i-pin windings, solving the problems of numerous solder joints and complex manufacturing processes of hairpin windings and i-pin windings.

[0003] The forming of flat copper wire (also known as flat wire, hereinafter referred to as flat wire for the sake of technical standardization) in traditional corrugated flat wire stators is exemplified by the "Continuous Corrugated 2D Forming Equipment and Control Method for Manufacturing Corrugated Flat Wire Stators, which relates to the field of new energy vehicle drive corrugated flat wire motor manufacturing technology, including a linear forming device, a linear conveying device, a linear support device, and a corrugated 2D forming unit" disclosed in Chinese Patent CN202410111947.3. In this continuous corrugated 2D forming equipment for manufacturing corrugated flat wire stators, the flat wire is bent and formed by the 2D forming unit. However, this forming equipment can only form each bend in the flat wire sequentially, resulting in excessively long forming time and low forming efficiency, which cannot meet the capacity requirements of modern production lines. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic wave forming machine to solve the defects of long forming time and low efficiency of flat wire in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A first forming device and a second forming device are provided, comprising a frame, a first forming device and a second forming device disposed on the frame; the first forming device includes a first support frame mounted on the frame, at least one first guide rail disposed on the first support frame and extending along a first direction, a plurality of first bending forming components movably mounted on the first guide rail, and a first spacing adjustment device supported on the first support frame and capable of moving the first bending forming components relative to the first guide rail; the second forming device includes a second support frame mounted on the frame and located below the first support frame, a first guide rail disposed on the second support frame and extending along a first direction, a plurality of first bending forming components movably mounted on the first guide rail, and a first spacing adjustment device. The device includes at least one second guide rail parallel to the first guide rail, a plurality of second bending forming components movably mounted on the second guide rail, and a second spacing adjustment device supported on a second support frame and capable of moving the second bending forming components relative to the second guide rail; the plurality of first bending forming components and the plurality of second bending forming components are arranged alternately in a first direction, each first bending forming component and each second bending forming component having a stamping space for bending the flat wire, the stamping spaces of the plurality of first bending forming components and the stamping spaces of the plurality of second bending forming components being sequentially connected to form a forming channel for inserting and removing the flat wire.

[0006] Compared with the prior art, the automatic corrugated wire forming machine provided by the present invention includes a frame, a first forming device, and a second forming device. The first forming device includes a first support frame, a first guide rail, a plurality of first bending forming components mounted on the frame, and a first spacing adjustment device that enables the first bending forming components to move relative to the first guide rail. The second forming device includes a second support frame, a second guide rail, a plurality of second bending forming components mounted on the frame and located below the first support frame, and a second spacing adjustment device that enables the second bending forming components to move relative to the second guide rail. The plurality of first bending forming components and the plurality of second bending forming components are arranged alternately in a first direction. Both the first bending forming components and the second bending forming components have a stamping space for bending flat wires. The stamping spaces of the plurality of first bending forming components and the stamping spaces of the plurality of second bending forming components are sequentially connected to form a forming channel for inserting and removing flat wires. In this way, the forming of flat wires can be achieved through the first bending forming components and the second bending forming components, which has the advantages of short forming time and high forming efficiency.

[0013] like Figures 1 to 3As shown, the automatic corrugated forming machine 1000 provided in this embodiment includes a frame 1001, a first forming device 100 and a second forming device 200 disposed on the frame 1001; the first forming device 100 includes a first support frame 11 mounted on the frame 1001, at least one first guide rail 12 disposed on the first support frame 11 and extending along a first direction D1, a plurality of first bending forming components 13 movably mounted on the first guide rail 12, and a first spacing adjustment device 14 supported on the first support frame 11 and capable of moving the first bending forming components 13 relative to the first guide rail 12; the second forming device 200 includes a second support frame 21 mounted on the frame 1001 and located below the first support frame 11, and a first spacing adjustment device 14 disposed on the second support frame 21. The system includes at least one second guide rail 22 parallel to at least one first guide rail 12, a plurality of second bending forming components 23 movably mounted on the second guide rail 22, and a second spacing adjustment device 24 supported on a second support frame 21 and capable of moving the second bending forming components 23 relative to the second guide rail 22; the plurality of first bending forming components 13 and the plurality of second bending forming components 23 are arranged alternately in a first direction D1, each first bending forming component 13 and each second bending forming component 23 having a stamping space 10a for bending the flat wire 90, the stamping spaces 10a of the plurality of first bending forming components 13 and the stamping spaces 10a of the plurality of second bending forming components 23 being sequentially connected to form a forming channel P for inserting and removing the flat wire 90.

[0014] The aforementioned automatic corrugated forming machine 1000 includes a frame 1001, a first forming device 100, and a second forming device 200. The first forming device 100 includes a first support frame 11 mounted on the frame 1001, a first guide rail 12, a plurality of first bending forming components 13, and a first spacing adjustment device 14 capable of moving the first bending forming components 13 relative to the first guide rail 12. The second forming device 200 includes a second support frame 21 mounted on the frame 1001 and located below the first support frame 11, a second guide rail 22, a plurality of second bending forming components 23, and a second spacing adjustment device 24 capable of moving the second bending forming components 23 relative to the second guide rail 22. Multiple first bending forming components 13 and multiple second bending forming components 23 are alternately arranged in the first direction D1. Both the first bending forming components 13 and the second bending forming components 23 have a stamping space 10a for bending the flat wire 90. The stamping spaces 10a of the multiple first bending forming components 13 and the stamping spaces 10a of the multiple second bending forming components 23 are connected in sequence to form a forming channel P for inserting and removing the flat wire 90. In this way, the flat wire 90 can be formed by the first bending forming components 13 and the second bending forming components 23. It has the advantages of short forming time and high forming efficiency. In addition, it improves the flexibility and adaptability of the equipment and reduces production costs.

[0015] See Figure 1 The automatic corrugated forming machine 1000 provided in this embodiment includes a frame 1001, a first forming device 100 and a second forming device 200. The frame 1001 has a first direction D1 and a second direction D2 that are perpendicular to each other. The plane formed by the first direction D1 and the second direction D2 is parallel to the bottom surface of the frame 1001. The first forming device 100 and the second forming device 200 are respectively supported on the frame 1001, and the second forming device 200 is located below the first forming device 100.

[0016] The first forming device 100 includes a first support frame 11, a first guide rail 12, a first bending forming component 13, and a first spacing adjustment device 14. The first support frame 11 is mounted on and supported by the frame 1001. The number of first guide rails 12 is not limited to two. The two first guide rails 12 are arranged in a direction perpendicular to the bottom surface of the frame 1001 (the vertical direction in the figure). Each first guide rail 12 extends along a first direction D1 (i.e., extends in a direction parallel to the first direction D1, hereinafter referred to as extending along the first direction D1). The first bending forming component 13 is movably mounted on the first guide rail 12. The first spacing adjustment device 14 is supported on the first support frame 11 and enables multiple first bending forming components 13 to move synchronously relative to the first guide rail 12. The second forming device 200 includes a second support frame 21, a second guide rail 22, a second bending forming component 23, and a second spacing adjustment device 24. The second support frame 21 is mounted on the frame 1001 and located below the first support frame 11. The second guide rail 22 is disposed on the second support frame 21 and is parallel to the first guide rail 12. The number of second guide rails 22 is not limited to two. The two second guide rails 22 are arranged in a direction perpendicular to the bottom surface of the frame 1001 (vertical direction in the figure). Each second guide rail 22 extends along a first direction D1. The second bending forming component 23 is movably mounted on the second guide rail 22. The distance adjustment device 24 is supported on the second support frame 21 and enables multiple second bending forming components 23 to move synchronously relative to the second guide rail 22. Multiple first bending forming components 13 and multiple second bending forming components 23 are arranged alternately in the first direction D1, and the projection portions of the first bending forming components 13 and the second bending forming components 23 on the side wall of the frame 1001 along the first direction D1 overlap. That is, the first bending forming component 13 in the first forming device 100 and the second bending forming component 23 in the second forming device 200 intersect in the direction perpendicular to the bottom surface of the frame 1001 (the up and down direction in the figure).

[0017] See Figure 17In this embodiment, the flat wire 90 is fed into the automatic corrugated forming machine 1000 in a straight line shape. After being formed by the first bending forming component 13 of the first forming device 100 and the second bending forming component 23 of the second forming device 200, it can be formed into a wavy (S-shaped) shape. It is worth mentioning that the first bending forming component 13 in the first forming device 100 forms a bend 90a on the same side of the straight flat wire 90 (the flat wire 90 is vertically supported by the automatic corrugated forming machine). On machine 1000, the bent portion on this side is located at the bottom of the flat wire 90, also called the lower bent portion or the lower roof. In the second forming device 200, the second bending forming component 23 forms the straight flat wire 90 to obtain the bent portion 90b on the other side (the bent portion on this side is located at the top of the flat wire 90, also called the upper bent portion or the upper roof). The part of the flat wire 90 located between the first forming device 100 and the second forming device 200 forms the straight portion 90c connecting the two bent portions 90a and 90b.

[0018] Figure 2 and Figure 3 The schematic diagrams show the workstation positions of each mechanism in the first molding device 100 and the second molding device 200 during the molding process.

[0019] Please return to the previous page. Figure 2 and Figure 3 In this embodiment, the stamping and mold closing directions of the first bending forming component 13 and the second bending forming component 23 are both perpendicular to the bottom surface of the frame 1001 (the vertical direction shown in the figure). Under the control of the first spacing adjustment device 14, the first bending forming component 13 in the first forming device 100 can move synchronously on the first guide rail 12 to realize the unfolding and retracting action among multiple first bending forming components 13. Under the control of the second spacing adjustment device 24, the second bending forming component 23 in the second forming device 200 can move synchronously on the second guide rail 22 to realize the unfolding and retracting action among multiple second bending forming components 23. Thus, under the control of the first spacing adjustment device 14 and the second spacing adjustment device 24, after the multiple first bending and forming components 13 are moved away from each other to the maximum spacing unfolded position and the multiple second bending and forming components 23 are moved away from each other to the maximum spacing unfolded position, loading and unloading 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 adjustment device 14 and the second spacing adjustment device 24 control the multiple first bending and forming components 13 to move towards each other to the minimum spacing converged position and the multiple second bending and forming components 23 to move towards each other to the minimum spacing converged position. At the same time, each first bending and forming component 13 and each second bending and forming component 23 closes the mold to form the flat wire 90.

[0020] See Figures 1 to 4In this embodiment, the number of first bending and forming components 13 in the first forming device 100 is, but not limited to, eight. The eight first bending and forming components 13 are arranged side by side in the first direction D1. The number of second bending and forming components 23 in the second forming device 200 is, but not limited to, nine. The nine second bending and forming components 23 are arranged side by side in the first direction D1. The first bending and forming components 13 and the second bending and forming components 23 are arranged alternately along the first direction D1.

[0021] from Figure 3 and Figure 4 As can be seen, in this embodiment, each first bending forming component 13 and each second bending forming component 23 has a stamping space 10a for bending the flat wire 90. The stamping spaces 10a of the multiple first bending forming components 13 and the stamping spaces 10a of the multiple second bending forming components 23 are sequentially connected to form a forming channel P for inserting and removing the flat wire 90. Under the control of the first spacing adjustment device 14 and the second spacing adjustment device 24, the first bending forming components 13 and the second bending forming components 23 move relative to each other to extend and shorten the forming channel P. After the first bending forming components 13 and the second bending forming components 23 are closed, the flat wire 90 in the forming channel P can be formed.

[0022] See Figures 4 to 6 The first spacing adjustment device 14 and the second spacing adjustment device 24 provided in this embodiment may have the same structure or different structure. In this embodiment, the first spacing adjustment device 14 and the second spacing adjustment device 24 have basically the same structure.

[0023] See Figures 4 to 10The first spacing adjustment device 14 and the second spacing adjustment device 24 provided in this embodiment both include a drive mounting plate 141 and a plurality of linkage assemblies 142 arranged along the first direction D1; each linkage assembly 142 includes a control rod 1421 and at least one pair of swing rods 1422, the at least one pair of swing rods 1422 being rotatably connected to each other, the control rod 1421 being rotatably connected to the middle of one of the at least one pair of swing rods 1422, and one end of the control rod 1421 being movably connected to the drive mounting plate 141 along the first direction D1; a linkage assembly 142 of the first spacing adjustment device 14 is provided between two adjacent first bending and forming assemblies 13, and at least one pair of swing rods 1422 in each linkage assembly 142 are rotatably connected to the two adjacent first bending and forming assemblies 13 respectively, the first spacing adjustment device 14 in The drive mounting plate 141 is movably mounted on the first support frame 11 along a first inclined direction T1 intersecting the first direction D1. The first spacing adjustment device 14 also includes a mounting plate drive mechanism 143 that enables the drive mounting plate 141 to move along the first inclined direction T1. A connecting rod assembly 142 of the second spacing adjustment device 24 is provided between two adjacent second bending and forming assemblies 23. At least one pair of swing rods 1422 in each connecting rod assembly 142 are rotatably connected to the two adjacent second bending and forming assemblies 23. The drive mounting plate 141 in the second spacing adjustment device 24 is movably mounted on the second support frame 21 along a second inclined direction T2 intersecting the first direction D1. The second spacing adjustment device 24 also includes a mounting plate drive mechanism 143 that enables the drive mounting plate 141 to move along the second inclined direction T2.

[0024] In this embodiment, each linkage assembly 142 of the first spacing adjustment device 14 includes a control rod 1421 and a swing rod 1422. The control rod 1421 extends in a direction perpendicular to the bottom surface of the frame 1001 (the up-down direction shown in the figure, which is also the mold opening direction). The number of swing rods 1422 is, but not limited to, two pairs. The two pairs of swing rods 1422 are spaced apart in a direction perpendicular to the bottom surface of the frame 1001 (the up-down direction shown in the figure, which is also the mold opening direction). One end (inner end) of the two swing rods 1422 in each pair is hinged to each other, and the other end (outer end) is rotatably connected to two adjacent first bending forming assemblies 13. The first support frame 11 is provided with an upper inclined guide rail 15 along a first inclined direction T1 intersecting the first direction D1. The drive mounting plate 141 of the first spacing adjustment device 14 is movably mounted on the upper inclined guide rail 15. The mounting plate drive mechanism 143 of the first spacing adjustment device 14 is supported on the first support frame 11. The mounting plate drive mechanism 143 is, but is not limited to, a motor screw drive mechanism. The mounting plate drive mechanism 143 enables the drive mounting plate 141 to move relative to the first support frame 11 along the first inclined direction T1. The upper end (the upper end shown in the figure) of the control rod 1421 is connected to the drive mounting plate 141 and can move relative to the drive mounting plate 141 along the first direction D1. Each linkage assembly 142 in the first spacing adjustment device 14 is respectively connected to two adjacent first bending forming assemblies 13. The two adjacent first bending forming assemblies 13 are rotatably connected to the outer end of the swing arm 1422 of the linkage assembly 142. It is easy to understand that, driven by the mounting plate drive mechanism 143 of the first spacing adjustment device 14, the drive mounting plate 141 of the first spacing adjustment device 14 moves up and down relative to the first support frame 11 along the first tilt direction T1 and drives the control rods 1421 of each linkage assembly 142 to move up and down together, and causes the control rods 1421 to move relative to the drive mounting plate 141 along the first direction D1. While the control rods 1421 are displaced, they can drive the swing rods 1422 in the linkage assembly 142 to rotate, thereby driving the first bending and forming assembly 13 to move relative to the first support frame 11 along the first direction D1, so as to realize that multiple first bending and forming assemblies 13 can be simultaneously unfolded and retracted on the first guide rail 12.

[0025] In this embodiment, each linkage assembly 142 of the second spacing adjustment device 24 includes a control rod 1421 and a swing rod 1422. The control rod 1421 extends in a direction perpendicular to the bottom surface of the frame 1001 (the up-down direction shown in the figure, which is also the mold opening direction). The number of swing rods 1422 is, but not limited to, two pairs. The two pairs of swing rods 1422 are spaced apart in a direction perpendicular to the bottom surface of the frame 1001 (the up-down direction shown in the figure, which is also the mold opening direction). One end (inner end) of the two swing rods 1422 in each pair is hinged to each other, and the other end (outer end) is rotatably connected to two adjacent second bending forming assemblies 23. The second support frame 21 is provided with a downward inclined guide rail 25 along a second inclined direction T2 intersecting the first direction D1. The second inclined direction T2 and the first inclined direction T1 are symmetrically arranged in the first direction D1. The drive mounting plate 141 of the second spacing adjustment device 24 is movably mounted on the downward inclined guide rail 25. The mounting plate drive mechanism 143 of the second spacing adjustment device 24 is supported on the second support frame 21. The mounting plate drive mechanism 143 is, but is not limited to, a motor screw drive mechanism. The mounting plate drive mechanism 143 enables the drive mounting plate 141 to move 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 is connected to the drive mounting plate 141 and can move relative to the drive mounting plate 141 along the first direction D1. Each linkage assembly 142 in the second spacing adjustment device 24 is respectively connected to two adjacent second bending forming assemblies 23. The two adjacent second bending forming assemblies 23 are rotatably connected to the outer end of the swing arm 1422 of the linkage assembly 142. It is easy to understand that, driven by the mounting plate drive mechanism 143 of the second spacing adjustment device 24, the drive mounting plate 141 of the second spacing adjustment device 24 moves up and down relative to the second support frame 21 along the second tilt direction T2 and drives the control rods 1421 of each linkage assembly 142 to move up and down together, and causes the control rods 1421 to move relative to the drive mounting plate 141 along the first direction D1. While the control rods 1421 are displaced, they can drive the swing rods 1422 in the linkage assembly 142 to rotate, thereby driving the second bending and forming assembly 23 to move relative to the second support frame 21 along the first direction D1, so as to realize that multiple second bending and forming assemblies 23 can be simultaneously unfolded and retracted on the second guide rail 22.

[0026] See Figures 4 to 10The first bending forming assembly 13 and the second bending forming assembly 23 provided in this embodiment both include a support plate 131, a hinge seat 132, an assembly seat 133, a punch 134, a die 135, and a stamping drive mechanism 136. The hinge seat 132, the assembly seat 133, the punch 134, the die 135, and the stamping drive mechanism 136 are all disposed on the support plate 131 and supported by the support plate 131. The hinge seat 132 is detachably mounted on the support plate 131, and a hinge portion 1321 is provided on the hinge seat 132, which is connected to the swing rod 1422. The mounting base 133 is movably mounted on the support plate 131, the punch 134 is detachably mounted on the mounting base 133, and the die 135 is detachably mounted on the support plate 131 and can open and close with the punch 134. A stamping space 10a is formed between the die 135 and the punch 134. The stamping drive mechanism 136 is used to drive the mounting base 133 to move to realize the opening and closing of the punch 134 and the die 135. The support plate 131 of the first bending forming assembly 13 is movably mounted on the first guide rail 12, and the support plate 131 of the second bending forming assembly 23 is movably mounted on the second guide rail 22.

[0027] In this embodiment, the support plate 131 extends in a direction perpendicular to the bottom surface of the frame 1001 (vertical direction in the figure). The mounting base 133, punch 134, die 135 and stamping drive mechanism 136 are located on the same side of the support plate 131, and the hinge base 132 is located on the other side of the support plate 131. A cavity for mounting the hinge base 132 is formed on the support plate 131. The support plate 131 is fixedly mounted on the support plate 131 with fasteners. The number of hinge bases 132 is not limited to two, and they correspond to two pairs of rocker arms 1422 respectively. The number of hinge parts 1321 of each hinge base 132 is not limited to two, and each hinge part 1321 is equipped with a pin connected to the rocker arm 1422. The stamping drive mechanism 136 is, but is not limited to, a motor screw mechanism. The mounting base 133 is connected to the stamping drive mechanism 136 and can move in a direction perpendicular to the bottom surface of the frame 1001 under the drive of the stamping drive mechanism 136. The die 135 is fixedly mounted on the support plate 131 with fasteners, and the punch 134 is detachably fixedly mounted on the mounting base 133. In this way, under the drive of the stamping drive mechanism 136, the punch 134 moves relative to the die 135 to realize the mold closing action, so as to form the flat wire 90. It should be noted that the hinge seat 132 and the die 135 are both installed on the support plate 131 in a detachable manner, and the punch 134 is installed on the assembly seat 133 in a detachable manner. In this way, when different specifications of flat wire 90 need to be formed, only the hinge seat 132, the die 135, and the punch 134 need to be replaced to match, thereby achieving quick replacement and improving the applicability of the first bending forming component 13 and the second bending forming component 23.

[0028] In other embodiments, the punch 134 is mounted on the support plate 131, and the die 135 is mounted on the mounting base 133.

[0029] See Figures 6 to 10 In this embodiment, a drive mounting plate 141 is provided with a track 144 extending along a first direction D1. A control rod 1421 is provided with a roller 1423 and an auxiliary wheel 1424. The roller 1423 is located at the end of the control rod 1421, and the roller 1423 and auxiliary wheel 1424 are located on both sides of the track 144 and connected to it. In this embodiment, a mounting rod 1425 is provided on the control rod 1421, and the auxiliary wheel 1424 is mounted on the mounting rod 1425. The roller 1423 and auxiliary wheel 1424 are slidably connected to both sides of the track 144. This makes the connection between the control rod 1421 and the drive mounting plate 141 more stable and the movement of the control rod 1421 smoother.

[0030] See Figures 1 to 7 The first forming device 100 provided in this embodiment also includes two third bending forming components 16. One of the two third bending forming components 16 is fixed on the first support frame 11, and the other is movably installed on the first guide rail 12 and connected to the first spacing adjustment device 14. The first bending forming component 13 and the second bending forming component 23 are both disposed between the two third bending forming components 16. Each third bending forming component 16 includes a forming upper mold 161 and a forming lower mold 162 that opens and closes with the forming upper mold 161 and bends the end of the flat wire 90.

[0031] See Figure 6 and Figure 7 In this embodiment, the first bending and forming component 13 and the third bending and forming component 16 are connected by the connecting rod assembly 142 of the first spacing adjustment device 14. Of the two third bending and forming components 16, the third bending and forming component 16 on the left (left side in the figure) is fixedly installed on the first support frame 11, while the third bending and forming component 16 on the right (right side in the figure) is movably installed on the first guide rail 12. Thus, under the drive of the mounting plate drive mechanism 143 of the first spacing adjustment device 14, the opening and retraction of each connecting rod assembly 142 drives the multiple first bending and forming components 13 and the third bending and forming component 16 on the right (right side in the figure) to move synchronously in the first direction D1, so as to realize the expansion and contraction of the multiple first bending and forming components 13 and the third bending and forming component 16 on the right (right side in the figure) relative to the third bending and forming component 16 on the left (left side in the figure). It should be noted that one of the first bending and forming components 13 can be fixed, while the other first bending and forming components 13 can move relative to the fixed first bending and forming component 13.

[0032] 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 first bending forming component 13 forms a straight flat line 90 to obtain a bent portion 90a (i.e., a lower bend) on the same side. The first bending forming component 13 can form eight lower bending portions 90a (located below the flat line 90 in the vertical direction of the figure), and the second bending forming component 23 can form nine upper bending portions 90b (located above the flat line 90 in the vertical direction of the figure). The two ends of the flat line 90 are bent downward (lower in the figure) by the third bending forming component 16, and the first and second ends are welded together to obtain new lower bending portions and lead-out sections.

[0033] See Figures 1 to 4 , Figure 6In this embodiment, a pressing device 300 is provided on the frame 1001. The pressing device 300 includes a pressing mounting base 310, a pressing drive mechanism (not shown), and a pressing block 320. The pressing mounting base 310 is movably mounted on the frame 1001 along the first direction D1. The pressing drive mechanism is used to move the pressing mounting base 310 along the first direction D1. The pressing block 320 is used to abut against the outer side of the third bending and forming component 16, which is movably mounted on the first guide rail 12. The pressing block 320 is movably mounted on the pressing mounting base 310 along the second direction D2. In this embodiment, the top-pressing drive mechanism is, but is not limited to, a motor screw mechanism. The top-pressing drive mechanism is connected to the top-pressing mounting base 310 and can drive the top-pressing mounting base 310 to move along the first direction D1. The top-pressing block 320 is mounted on the top-pressing mounting base 310, and its bottom is provided with a driving component (not shown in the figure), which allows the top-pressing block 320 to move relative to the top-pressing mounting base 310 along the second direction D2, realizing the extension and retraction of the top-pressing block 320 on the top-pressing mounting base 310. It can be understood that after the first bending forming component 13 and the movable third bending forming component 16 are retracted towards the fixed third bending forming component 16, the top-pressing drive mechanism drives the top-pressing mounting base 310 to drive the top-pressing block 320. The first bending forming component 13 and the second bending forming component 23 move toward the fixed third bending forming component 16 and abut against the movable third bending forming component 16. When the first bending forming component 13 and the movable third bending forming component 16 move away from the fixed third bending forming component 16, the top pressing block 320 retracts to avoid mutual interference with the first bending forming component 13 and the third bending forming component 16. Under the drive of the top pressing drive mechanism, it moves with the top pressing mounting base 310 to reset. In this way, the top pressing device 300 can press the first bending forming component 13, the second bending forming component 23, and the third bending forming component 16 together to eliminate the gap between each bending forming component and improve the forming quality.

[0034] See Figure 3 In this embodiment, the second forming device 200 further includes a reset device 500, which includes a reset block 510 and a reset drive mechanism 520. The reset drive mechanism 520 is supported on the second support frame 21 and is used to move the reset block 510 along the first direction D1. The reset drive mechanism 520 is, but is not limited to, a linear module. The reset block 510 is used to abut against the second bending forming component 23 of the third bending forming component 16 that is fixedly installed on the first guide rail 12. The reset block 510 is connected to the reset drive mechanism 520. In this way, the reset block 510 can be driven to move by the reset drive mechanism 520, and the reset block 510 can push the second bending forming component 23 to move, so as to ensure that the second bending component is reset.

[0035] See Figures 1 to 3In this embodiment, a vertical rail 61 is provided on the frame 1001. The vertical rail 61 extends in a direction perpendicular to the bottom surface of the frame 1001. The first support frame 11 and the second support frame 21 are respectively movably mounted on the vertical rail 61 of the frame 1001. A first lifting drive mechanism 62 for driving the first support frame 11 to rise and fall is provided at the top of the frame 1001. A second lifting drive mechanism 63 for driving the second support frame 21 to rise and fall is provided at the bottom of the frame 1001. The first lifting drive mechanism 62 and the second lifting drive mechanism 63 are, but are not limited to, motor screw mechanisms. Thus, during molding, the first support frame 11 and the second support frame 21 are controlled to move towards each other by the first lifting drive mechanism 62 and the second lifting drive mechanism 63 respectively. The punch 134 of the second bending forming component 23 in the second forming device 200 abuts against the flat wire 90 to improve the molding effect.

[0036] See Figure 11 The line leveling device 400 provided in this embodiment is disposed on one side of the frame 1001 and located between the first forming device 100 and the second forming device 200. The line leveling device 400 includes a first pulling device 410 and a second pulling device 420. The first pulling device 410 and the second pulling device 420 are both installed on a leveling support frame (not shown in the figure) (or can be directly installed on the frame 1001). The first pulling device 410 and the second pulling device 420 are arranged at intervals along the first direction D1. The first pulling device 410 includes a first pulling base 411, a first wire carrier 412, a first wire pressing mechanism 413, and a first pulling drive mechanism 414 located in the middle of the frame 1001. The first wire carrier 412 is disposed on the first pulling base 411. A first wire groove 4121 is formed on the surface of the first wire carrier 412 for inserting the end of the flat wire 90 and extending along the first direction D1. The first wire pressing mechanism 413 is disposed on the first pulling base 411 and is used to press the end of the flat wire 90 against the first wire carrier 412. The first pulling drive mechanism 414 is connected to the first pulling base 411 and is used to move the first pulling base 411 along the first direction D1. The second pulling device 420 includes a second pulling base 421, a second wire carrier 422, a second wire pressing mechanism 423, and a second pulling drive mechanism 424. The second pulling base 421 is arranged side by side and spaced apart from the first pulling base 411 in the first direction D1. The second wire carrier 422 is disposed on the second pulling base 421. The surface of the second wire carrier 422 is formed with a second wire groove 4221 for inserting the end of the flat wire 90 and extending along the first direction D1. The second wire pressing mechanism 423 is disposed on the second pulling base 421 and is used to press the end of the flat wire 90 against the second wire carrier 422. The second pulling drive mechanism 424 is connected to the second pulling base 421 and is used to move the second pulling base 421 along the first direction D1. The second wire pressing mechanism 423 includes a non-metallic contact block 425 for contacting the flat wire 90.

[0037] 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.

[0038] See Figure 11 , Figure 14 , Figure 15In this embodiment, the number of first wire slots 4121 on the first wire carrier 412 is multiple, and the multiple first wire slots 4121 are arranged along the second direction D2; the number of second wire slots 4221 on the second wire carrier 422 is multiple, and the multiple second wire slots 4221 are arranged along the second direction D2.

[0039] See Figures 11 to 13 The first pressing mechanism 413 provided in this embodiment includes a punch mounting base 4131, a pressing punch 4132 for pressing the end of the flat wire 90 on the first wire carrier 412 against the first wire carrier 412, and a punch driving assembly 4133 for driving the pressing punch 4132 to rise and fall. The punch mounting base 4131 is mounted on the first traction base 411, and the pressing punch 4132 is movably mounted on the punch mounting base 4131 and located above the first wire carrier 412. The punch driving assembly 4133 includes a punch power component 41331 and a punch connecting rod 41332 rotatably mounted on the punch mounting base 4131. One end of the punch connecting rod 41332 is hinged to the pressing punch 4132, and the other end is hinged to the punch power component 41331. The punch power component 41331 is rotatably mounted on the first traction base 411. In this embodiment, the first wire carrier 412 and the punch mounting base 4131 are fixedly mounted on the first traction base 411 by screws, welding or any other existing fixing method. The wire pressing punch 4132 is movably mounted on the punch mounting base 4131 in a direction perpendicular to the surface of the first traction base 411 and is located above the first wire carrier 412. The punch drive assembly 4133 includes a punch power member 41331 and a punch connecting rod 41332. The middle part of the punch connecting rod 41332 is hinged to the top of the punch mounting base 4131. The two ends of the punch connecting rod 41332 are respectively hinged to the top of the punch power member 41331 and the top of the pressing punch 4132. The punch power member 41331 is rotatably mounted on the first traction base 411. The punch power member 41331 is, but is not limited to, a cylinder. 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, causing the pressing punch 4132 to move up and down. In this way, after the end of the flat wire 90 is placed on the first wire carrier table 412, the punch power member 41331 drives the pressing punch 4132 to descend onto the first wire carrier table 412, thereby pressing the flat wire 90 onto the first wire carrier table 412.

[0040] See Figure 13The punch mounting base 4131 provided in this embodiment has a punch groove 41311 for the wire pressing punch 4132 to slide. Both ends of the wire pressing punch 4132 extend beyond the punch groove 41311. In this embodiment, the punch groove 41311 is located above the first wire carrier 412. The punch groove 41311 extends in a direction perpendicular to the surface of the first tension base 411, and both ends penetrate the surface of the punch mounting base 4131. In this way, by forming the punch groove 41311 on the punch mounting base 4131 to install the wire pressing punch 4132, it can be ensured that the wire pressing punch 4132 moves more smoothly and the wire pressing effect is improved.

[0041] See Figure 13 In this embodiment, the bottom end of the pressing punch 4132 is formed with a plurality of teeth 4132a for contacting the flat wire 90. The plurality of teeth 4132a are arranged along the first direction D1. In this way, by forming a plurality of teeth 4132a on the bottom end of the pressing punch 4132, the flat wire 90 can be prevented from sliding after pressing.

[0042] See Figures 11 to 13 The first traction base 411 provided in this embodiment 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 that can drive the end flattening block 415 to move along the first direction D1; 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, but is not limited to, a cylinder. The flattening power member 416 is fixedly installed on the first traction base 411 and located on the side of the first wire carrier 412 away from the second wire carrier 422. The end flattening block 415 is located between the first wire carrier 412 and the flattening power member 416 and is fixed on the output shaft of the flattening power member 416. The side of the end flattening block 415 facing the first wire carrier 412 has a plane perpendicular to the surface of the first traction base 411. Thus, after the flat wire 90 is inserted, the flattening power member 416 drives the end flattening block 415 to move along the first direction D1. After it abuts against the end of the flat wire 90, it can push the flat wire 90 to a predetermined position. Alternatively, after the ends of multiple flat wires 90 abut against each other, the ends of multiple flat wires 90 can be pushed onto the same plane so that the ends of each flat wire 90 are flush.

[0043] See Figure 11 , Figures 14 to 16The second wire pressing mechanism 423 provided in this embodiment includes a wire pressing seat mounting bracket 4231, a wire pressing seat 4232 for pressing the end of the flat wire 90 on the second wire carrier 422 onto the second wire carrier 422, and a wire pressing seat driving assembly 4233 for driving the wire pressing seat 4232 to move up and down; the wire pressing seat mounting bracket 4231 is mounted on the second tension base 421, the wire pressing seat 4232 is movably mounted on the wire pressing seat mounting bracket 4231, the wire pressing seat driving assembly 4233 is supported on the wire pressing seat mounting bracket 4231 and connected to the wire pressing seat 4232; and a contact block 425 is mounted on the bottom of the wire pressing seat 4232. In this embodiment, the wire clamp mounting bracket 4231 is installed on the second traction base 421 using any existing fixing method such as screws or welding. The wire clamp 4232 is installed on the wire clamp mounting bracket 4231 and corresponds to the position of the second wire carrier 422. The wire clamp driving assembly 4233 is, but is not limited to, an electric cylinder. The wire clamp driving assembly 4233 is supported on the top of the wire clamp mounting bracket 4231 and connected to the wire clamp 4232. The contact block 425 is embedded in the wire clamp 4232 and located on the side of the wire clamp 4232 facing the second wire carrier 422. Thus, by adding a non-metallic contact block to the wire clamp 4232... 425. After the flat wire 90 is placed in, the wire pressing seat drive assembly 4233 drives the wire pressing seat 4232 to descend. The contact block 425 abuts against the flat wire 90 and presses the flat wire 90 onto the second wire carrier 422. The first pulling drive mechanism 414 drives the first pulling base 411 to move away from the second pulling device 420 along the first direction D1 to flatten the flat wire 90. Since the contact block 425 is made of non-metallic material and 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, thereby preventing damage to the paint of the flat wire 90 and affecting product quality.

[0044] See Figure 11 , Figures 14 to 16The second traction base 421 provided in this embodiment includes a front seat 4211 and a rear seat 4212 arranged side by side and spaced apart in the first direction D1. The front seat 4211 is located on the side of the rear seat 4212 close to the first traction base 411, and the second pressing mechanism 423 is supported on the front seat 4211. The rear seat 4212 is provided with an elastic drive member 426 for providing a pulling force to the front seat 4211 in the first direction D1 away from the direction of the first traction base 411. The elastic drive member 426 is connected to the front seat 4211. The second traction drive mechanism 424 is connected to the rear seat 4212. In this embodiment, the front seat 4211 and the rear seat 4212 are movably mounted on the second leveling guide rail 45 of the pulling base 44 via sliders. Driven by the second pulling drive mechanism 424, the front seat 4211 and the rear seat 4212 can move together along the first direction D1. The front seat 4211 and the rear seat 4212 can move relative to each other. It should be noted that during the stamping process of the flat wire 90, the first pulling base 411 on the first pulling device 410 remains stationary, and the first wire pressing mechanism 413 and the first wire carrier 412 clamp one end of the flat wire 90. With the flat wire 90 bent and deformed at any time, the second pulling drive mechanism 424 drives the second pulling base 421 to move at a set speed. That is, while the flat wire 90 bends and shrinks, the second pulling base 421 of the second pulling device 420 clamps the other end of the flat wire 90 and moves it toward the first pulling device 410 to realize the wire feeding action. At the same time, the elastic drive member 426 on the rear seat 4212 provides a pulling force to the front seat 4211 in a direction away from the first pulling base 411. In this way, the flat wire 90 can always be kept taut during the forming process, thereby improving the forming effect.

[0045] See Figure 11 , Figures 14 to 16 In this embodiment, the elastic drive member 426 is a compensation cylinder, which is mounted on the rear seat 4212 and the output shaft of the compensation cylinder is fixed to the front seat 4211.

[0046] See Figure 11 , Figures 14 to 16 In this embodiment, the second traction drive mechanism 424 is, but is not limited to, a linear module, which has a sliding part that can move along the first direction D1. The sliding part is fixedly connected to the rear seat body 4212 by screws, welding or any other existing fixing method.
