Description

Technical Field

[0001] This utility model relates to the field of bending and forming technology, and in particular to a copper-aluminum strip bending and forming device. Background Technology

[0002] Copper-aluminum busbar bending is a plastic processing technique for two conductive metal materials, copper and aluminum busbars. The purpose is to use external force to cause permanent bending deformation at a specific location, thereby obtaining the desired geometric shape.

[0003] Patent CN223185261U discloses an assembly bending fixture. It includes a chassis with a column mounted on top, a chassis on top of the column, and clamping blocks movably mounted on top of the chassis. A turntable is rotatably connected to the outside of the column, and a drive assembly is connected to the turntable. When using this patent, the bending grooves on the inner sides of the two sets of clamping blocks fit tightly against the copper / aluminum busbar. Activating the drive assembly inside the chassis rotates the turntable, thereby rotating the bending assembly for bending. However, this existing patent still has some shortcomings in practical use. Because the two clamping blocks are fixed to the chassis, the distance between them cannot be adjusted, resulting in the ability to process copper / aluminum busbars within a specific width range. Each time a workpiece of a different width is changed, the machine must be stopped, the current fixture removed, and a new fixture of the corresponding width installed and calibrated.

[0004] Therefore, there is a need to provide a copper and aluminum busbar bending and forming device that can adapt to various sizes. Utility Model Content

[0005] To overcome the shortcomings of the existing patent where the two clamping blocks are fixed to the chassis and the distance between the two clamping blocks cannot be adjusted, resulting in the only processing of copper and aluminum busbars within a specific width range, and requiring the machine to be stopped, the current fixture removed, and a new fixture of the corresponding width to be installed and calibrated every time a workpiece of a different width is changed, this utility model provides a copper and aluminum busbar bending and forming device that can adapt to multiple sizes.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a copper-aluminum strip bending and forming device, comprising a support frame, a worktable, a servo motor, a drive gear, a rotating shaft, a driven gear, and a limiting mechanism. The worktable is fixedly connected to the support frame, a servo motor is installed within the worktable, and a drive gear is keyed to the output shaft of the servo motor. A rotating shaft is rotatably mounted on the worktable, and a driven gear is fixedly connected to the rotating shaft. The drive gear meshes with the driven gear. A limiting mechanism is provided on the worktable, further comprising a lower limiting plate, a lower clamping block, first guide rods, a lifting screw, an upper limiting plate, and an upper clamping block. The lower limiting plate is fixedly connected to the driven gear, and a lower clamping block is fixedly connected to the lower limiting plate. Four first guide rods are fixedly connected to the lower limiting plate, and an upper limiting plate is slidably mounted between the four first guide rods. A lifting screw is rotatably mounted on the lower limiting plate, and the upper limiting plate is threadedly connected to the lifting screw. An upper clamping block is fixedly connected to the upper limiting plate.

[0007] As an improvement to the above solution, it also includes a slider, a support plate, and an adjusting screw. A guide groove is opened on the worktable, and a slider is slidably installed in the guide groove. An adjusting screw is rotatably installed on the worktable, and a slider is threaded onto the adjusting screw. A support plate is fixedly connected to the slider.

[0008] As an improvement to the above solution, the limiting mechanism includes a fixed seat, a second guide rod, a first elastic element, a mounting seat, and limiting wheels. A fixed seat is provided on the worktable, and two second guide rods are fixedly connected to the fixed seat. A mounting seat is fixedly connected between the two second guide rods. Two limiting wheels are rotatably arranged inside the mounting seat. A first elastic element is sleeved on the second guide rod, and the two ends of the first elastic element are respectively connected to the second guide rod and the fixed seat.

[0009] As an improvement to the above solution, it also includes an inclined block, a third guide rod, a second elastic element, a pressing block, a sliding frame, and a pedal. The inclined block is fixedly connected to the fixed base, the sliding frame is slidably arranged on the worktable, the pedal is fixedly connected to the sliding frame, the pressing block is fixedly connected to the sliding frame, two third guide rods are fixedly connected to the pressing block, the second elastic element is sleeved on the third guide rod, and the two ends of the second elastic element are respectively connected to the third guide rod and the fixed base.

[0010] As an improvement to the above solution, anti-slip grooves are provided on the pedal.

[0011] As an improvement to the above solution, it also includes scale lines, with scale lines set on the worktable.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By rotating the lifting screw, the lifting screw drives the upper limit plate and the upper clamping block to move up and down, so that the upper clamping block moves away from or closer to the lower clamping block, thereby adjusting the distance between the upper clamping block and the lower clamping block, so as to bend copper and aluminum bars of different sizes.

[0013] 2. By stepping down on the pedal, the anti-slip groove on it effectively prevents the foot from slipping when stepping. The pedal drives the sliding frame and the extrusion block to move downward. The extrusion block presses against the inclined block on the fixed seat, causing the inclined block to drive the mounting seat and the two second guide rods to move forward. The fixed seat pushes the entire mounting seat and the two limit wheels to move forward, so that the two limit wheels limit the copper and aluminum busbars in the front and back.

[0014] 3. By rotating the adjusting screw, the slider is driven to slide horizontally along the guide groove on the worktable, which in turn drives the slide to move the support plate synchronously, thereby limiting the end of the copper and aluminum busbar for precise positioning.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] Example 1: A copper-aluminum strip bending and forming device, see reference. Figures 1-5As shown, the device includes a support frame 1, a worktable 2, a servo motor 3, a drive gear 4, a rotating shaft 5, a driven gear 6, and a limiting mechanism. The worktable 2 is welded to the top of the support frame 1. The servo motor 3 is bolted inside the worktable 2. The drive gear 4 is keyed to the output shaft of the servo motor 3. The rotating shaft 5 is rotatably mounted in the middle of the worktable 2. The driven gear 6 is fixedly connected to the rotating shaft 5. The drive gear 4 meshes with the driven gear 6. The worktable 2 is equipped with a limiting mechanism for limiting the movement of the copper and aluminum bars, and also includes a lower limiting plate. 7. Lower clamping block 8, first guide rod 9, lifting screw 10, upper limit plate 11 and upper clamping block 12. The driven gear 6 is fixedly connected to the top of the lower limit plate 7. The lower clamping block 8 is fixedly connected to the lower limit plate 7. Four first guide rods 9 are fixedly connected to the lower limit plate 7 at even intervals. The upper limit plate 11 is slidably arranged between the four first guide rods 9. The lifting screw 10 is rotatably arranged in the middle of the lower limit plate 7. The upper limit plate 11 is threadedly connected to the lifting screw 10. The upper clamping block 12 is fixedly connected to the upper limit plate 11. The upper clamping block 12 is aligned with the lower clamping block 8.

[0024] When using this device, by rotating the lifting screw 10, the lifting screw 10 drives the upper limit plate 11 and the upper clamping block 12 to move up and down, so that the upper clamping block 12 moves away from or closer to the lower clamping block 8, thereby adjusting the distance between the upper clamping block 12 and the lower clamping block 8, so that copper and aluminum bars of different sizes can be bent. The upper clamping block 12 and the lower clamping block 8 are used to limit the copper and aluminum bars up and down, and then the limiting mechanism is used to limit the copper and aluminum bars forward and backward. After the limiting is completed, the servo motor 3 is started. The output shaft of the servo motor 3 drives the drive gear 4 to rotate. The drive gear 4 drives the driven gear 6 and the rotating shaft 5 that mesh with it to rotate, providing bending power, thereby performing bending.

[0025] Example 2: Based on Example 1, refer to Figure 1 , Figure 4 and Figure 5 As shown, the limiting mechanism includes a fixed base 1601, a second guide rod 17, a first elastic element 18, a mounting base 19, and a limiting wheel 20. The fixed base 1601 is provided on the top of the worktable 2. The second guide rods 17 are symmetrically provided on the left and right sides of the rear side of the fixed base 1601 by welding. The second guide rods 17 slide on the fixed base 1601. The mounting base 19 is fixedly connected between the front ends of the two second guide rods 17. The left and right sides of the mounting base 19 are rotatably provided with limiting wheels 20. The first elastic element 18 is sleeved on the second guide rod 17. The two ends of the first elastic element 18 are respectively connected to the second guide rod 17 and the fixed base 1601.

[0026] See Figure 1 , Figure 5 and Figure 6As shown, it also includes a ramp block 21, a third guide rod 22, a second elastic element 23, a pressing block 24, a sliding frame 25, and a pedal 26. The ramp block 21 is fixedly connected to the rear side of the fixed base 1601. The sliding frame 25 is slidably provided at the rear of the worktable 2. The pedal 26 is fixedly connected to the lower part of the sliding frame 25. The pressing block 24 is fixedly connected to the top of the sliding frame 25. The pressing block 24 is in contact with the ramp block 21. The third guide rod 22 is symmetrically fixedly connected to the top of the pressing block 24. The third guide rod 22 passes through the fixed base 1601. The second elastic element 23 is sleeved on the third guide rod 22. The two ends of the second elastic element 23 are respectively connected to the third guide rod 22 and the fixed base 1601.

[0027] See Figure 6 As shown, the top of the pedal 26 has an anti-slip groove 27.

[0028] When the limiting mechanism is used, stepping down on the pedal 26 causes the anti-slip groove 27 to effectively prevent the foot from slipping. The pedal 26 moves the sliding frame 25 and the pressing block 24 downwards. The pressing block 24 presses against the inclined block 21 on the fixed base 1601, causing the inclined block 21 to move the mounting base 19 and the two second guide rods 17 forward. The first elastic element 18 is compressed accordingly, pushing the entire mounting base 19 and the two limiting wheels 20 forward, so that the two limiting wheels 20 limit the copper and aluminum busbars in the front and rear. Conversely, when the pedal 26 is released, the first elastic element 18 moves the mounting base 19 back to its original position. When the copper-aluminum busbar is fed between the two limiting wheels 20, the limiting wheels 20 roll to reduce the feeding resistance, and at the same time use elastic pressure to hold the material in place, playing a guiding and initial limiting role, preventing the material from shifting or warping during bending. As the extrusion block 24 moves downward, the extrusion block 24 drives the two third guide rods 22 to move downward to extrude the second elastic element 23. The second elastic element 23 is compressed accordingly. After the mounting base 19 is reset, the mounting base 19 drives the inclined block 21 to push the extrusion block 24. The second elastic element 23 then rebounds, driving the third guide rods 22 and the extrusion block 24 to reset.

[0029] See Figure 2 , Figure 4 and Figure 5 As shown, it also includes a slider 14, a support plate 15, and an adjusting screw 16. A guide groove 13 is opened on the right side of the worktable 2, and the slider 14 is slidably arranged in the guide groove 13. The adjusting screw 16 is rotatably arranged on the right side of the worktable 2. The adjusting screw 16 is located in the guide groove 13, and the slider 14 is threaded on the adjusting screw 16. The slider 14 slides in the guide groove 13, and the support plate 15 is welded to the top of the slider 14.

[0030] See Figure 4 As shown, it also includes a scale line 28. The scale line 28 is provided on the top of the worktable 2 and is located on the side of the guide groove 13.

[0031] Before bending, by rotating the adjusting screw 16, the slider 14 is driven to slide horizontally along the guide groove 13 on the worktable 2, which drives the slider 14 to move synchronously with the support plate 15, thereby limiting the end of the copper and aluminum busbar for precise positioning, thus ensuring that the bending angle and bending edge length are at the specified position. The scale line 28, in conjunction with the sliding support plate 15, provides the operator with a precise visual reference.

Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
