Description

Technical Field

[0001] This invention belongs to the field of stamping and bending technology, specifically relating to a stamping and bending equipment for producing transformer pole clamps. Background Technology

[0002] Transformer pole clamps are commonly used electrical wiring hardware, mainly used with transformer conductive poles. They rely on the clamp to hold the round pole body to achieve a fixed connection, which can firmly hold the power conductor, has stable conductivity, is easy to install and disassemble, is suitable for outdoor power distribution scenarios, and is stable under force and not easy to loosen or fall off.

[0003] The stamping and bending equipment used in the production of transformer pole clamps is a special processing equipment for bending and shaping metal plates for clamps. It completes the workpiece shaping and bending process by applying pressure through a mold, accurately shaping the clamp's clamping structure and holding shape. The processing results in a neat and consistent shape, which is suitable for mass production of clamps and ensures the fit and strength of the finished product.

[0004] Patent application CN121551441A discloses a stamping and bending equipment for producing transformer pole-mounted wire clamps. The multi-layered support structure of the clamp holder, positioning plate, and support rod ensures the overall stability of the material guiding assembly and can accommodate wire clamp raw materials of different thicknesses and widths. Furthermore, the mounting frame's position does not interfere with the stamping and forming assembly or the demolding assembly, improving the overall structural compatibility of the equipment. While this equipment can stamp and bend wire clamp raw material sheets for wire clamp production, in practical use, it can only stamp and bend wire clamp raw materials of different widths and thicknesses within the same type. It cannot achieve the function of switching between stamping and bending multiple types of wire clamp raw materials. When stamping and bending different types of wire clamp raw materials, different types of equipment need to be used, resulting in poor adaptability. Summary of the Invention

The first motor 24 is used to drive the square block 12 to rotate.

[0035] An L-shaped mounting bracket 25 is provided above the base 1 at the position corresponding to the first motor 24. The first motor 24 is connected to the mounting bracket 25, and the rotating shaft 23 passes through the mounting bracket 25. A bushing 251 is connected to the mounting bracket 25 at the position corresponding to the rotating shaft 23. The rotating shaft 23 and the bushing 251 are rotatably connected. The mounting bracket 25 is used to support and fix the first motor 24, and the bushing 251 is used to enhance the stability of the rotating shaft 23.

[0036] A second electric cylinder 26 is connected to the middle of the lower surface of the mounting bracket 25, and the lower end of the second electric cylinder 26 is connected to the base 1. The second electric cylinder 26 is used to drive the mounting bracket 25 to rise and fall, thereby driving the square block 12 to rise and fall.

[0037] Limiting rods 262 are connected to the four corners of the lower surface of the mounting bracket 25, and limiting sleeves 261 are connected to the upper surface of the base 1 at the corresponding positions of the limiting rods 262. The limiting rods 262 and the limiting sleeves 261 are slidably connected. The limiting rods 262 and the limiting sleeves 261 cooperate to enhance the stability of the mounting bracket 25 and prevent the mounting bracket 25 from shifting.

[0038] Please see Figure 5 and Figure 6 As shown, a mounting plate 3 is connected above the mounting bracket 25, and a third electric cylinder 31 is connected to the upper surface of the mounting plate 3. The mounting plate 3 is used to support and fix the third electric cylinder 31, and the third electric cylinder 31 is used to drive the U-shaped plate 32 to move.

[0039] The output end of the third electric cylinder 31 is connected to a U-shaped plate 32, which is used to support and fix the ring 321.

[0040] A turntable 323 is provided in the middle of the ring 321. A number of fixed blocks 322 arranged in a circular array are connected to the inner side of the ring 321 corresponding to the position of the turntable 323. The fixed blocks 322 are provided with rotating grooves 324 corresponding to the position of the turntable 323. The turntable 323 is rotatably connected to the rotating grooves 324. The fixed blocks 322 cooperate with the rotating grooves 324 to limit the position of the turntable 323.

[0041] A second motor 326 is connected to the middle of the turntable 323 near the U-shaped plate 32, and the second motor 326 is connected to the U-shaped plate 32. The second motor 326 is used to drive the turntable 323 to rotate.

[0042] The turntable 323 has multiple circumferentially arranged spiral grooves 325. Each spiral groove 325 is slidably connected to a moving rod 327. Each end of the moving rod 327 is connected to an anti-detachment block 328. Each anti-detachment block 328 is connected to a sliding rod 329 at the end away from the turntable 323. A fixed block 322 has a sliding groove 3210 corresponding to the position of the sliding rod 329. The sliding rod 329 is slidably connected to the sliding groove 3210. The anti-detachment block 328 is used to prevent the moving rod 327 from detaching from the spiral groove 325. The fixed block 322, together with the sliding groove 3210, is used to limit the position of the sliding rod 329. When the turntable 323 rotates, the spiral groove 325, together with the anti-detachment block 328 and the sliding rod 329, causes the moving rod 327 to move closer to or away from the center point of the turntable 323.

[0043] Each anti-detachment block 328 away from the U-shaped plate 32 is connected to a push rod 3211, which is used to push out the wire clamp after it has been stamped and bent.

[0044] Please see Figure 8 As shown, a first rack 42 is vertically connected to the side of the mounting frame 25 near the placement frame 14. A support 44 is connected to the upper surface of the support frame 2 at the position corresponding to the first rack 42. A gear 43 is rotatably connected above the support 44. The first rack 42 meshes with the gear 43. A second rack 45 is horizontally connected to the placement frame 14 near the mounting frame 25. The second rack 45 meshes with the gear 43. The first rack 42 and the second rack 45 are staggered. The first rack 42 cooperates with the gear 43 and the second rack 45 to move the placement frame 14 closer to or away from the square block 12.

[0045] Please see Figure 3 As shown, a fourth electric cylinder 5 is connected to the lower surface of the placement rack 14. A push plate 51 is connected to the output end of the fourth electric cylinder 5, and the push plate 51 is located above the placement rack 14. The fourth electric cylinder 5 is used to drive the push plate 51 to move, and the push plate 51 is used to push the metal plate toward the square block 12.

[0046] Please see Figure 6As shown, the square block 12 has four storage slots 52 arranged in a circular array. Each storage slot 52 is slidably connected to a baffle 53. Multiple evenly arranged first springs 54 are connected between the baffle 53 and the square block 12. The first springs 54 are located in the storage slots 52. The storage slots 52 are used to store the first springs 54 and the baffles 53. The baffles 53 are used to block the metal plate.

[0047] Please see Figures 1 to 3 as well as Figure 9 As shown, a placement box 6 is provided above the placement rack 14, and a push plate 51 is located between the placement rack 14 and the placement box 6. The placement box 6 is used to place metal plates.

[0048] The top of the placement box 6 is connected to a symmetrically arranged sliding plate 61. The top plate 11 is provided with a symmetrically arranged slide rail 62 corresponding to the position of the sliding plate 61. The sliding plate 61 and the slide rail 62 are slidably connected. The sliding plate 61 and the slide rail 62 are used to initially define the position of the placement box 6.

[0049] A positioning block 63 is connected to the lower surface of the top plate 11 at the position corresponding to the placement box 6. A positioning rod 64 is slidably connected to the middle of the positioning block 63. A positioning sleeve 65 is connected to the placement box 6 at the position corresponding to the positioning rod 64. The positioning rod 64 and the positioning sleeve 65 are inserted and engaged. A pull block 66 is connected to the end of the positioning rod 64 away from the positioning sleeve 65. A second spring 67 is connected between the positioning block 63 and the pull block 66. The positioning block 63, together with the positioning rod 64 and the positioning sleeve 65, is used to fix the position of the placement box 6. The second spring 67 is used to reset the pull block 66 and the positioning rod 64.

[0050] Working principle: Before producing the wire clamp, the upper mold 13 and the placement box 6 are replaced according to the type of wire clamp to be produced. The square block 12 is rotated to adjust the position of the lower mold 121 (that is, the lower mold 121 of the required shape for the wire clamp is rotated to the top of the square block 12), and the position of the ejector rod 3211 is adjusted. The specific operations are as follows: First, remove the screws that fix the upper mold 13, thereby removing the upper mold 13 and identifying the upper mold 13 that needs to be replaced. Next, start the second electric cylinder 26. The second electric cylinder 26 lifts the mounting bracket 25, the first motor 24, and the square block 12, causing the insertion rod 21 to disengage from the slot 22. During the lifting of the mounting bracket 25, the first rack 42 rises synchronously. During the rise of the first rack 42, the gear 43 is driven to rotate. The rotation of the gear 43 drives the second gear 43 and the placement bracket 14 to move away from the square block 12, thereby avoiding the placement bracket 14 from affecting the square block 12 during the rotation of the square block 12. After the mounting bracket 25 is lifted, the first motor 24 is activated. The first motor 24 rotates 90°, 180°, or 270° to align the upper mold 13 to be replaced with one of the lower molds 121. After rotation, the second electric cylinder 26 is activated again. The second electric cylinder 26 drives the mounting bracket 25, the first motor 24, and the square block 12 to descend, so that the insertion rod 21 is inserted into the slot 22 again to position the square block 12 and to make the lower surface of the square block 12 fit against the upper surface of the support frame 2. During the descent of the mounting bracket 25, the first rack 42 is driven to descend. The descent of the first rack 42 drives the gear 43 to reverse. The reverse rotation of the gear 43 drives the second gear 43 and the placement frame 14 to move closer to the square block 12, thereby ensuring that the metal plate on the placement frame 14 is stably pushed onto the square block 12. After the mounting bracket 25 is lowered, the upper mold 13 to be replaced is installed on the lifting plate 132 by screws; After the upper mold 13 is replaced, the second motor 326 is started. The second motor 326 drives the turntable 323 to rotate. The turntable 323 rotates and drives the spiral groove 325 to rotate. During the rotation, the spiral groove 325 cooperates with the fixed block 322, the slide rod 329 and the slide groove 3210 to move the moving rod 327. The slide rod 329 and the slide groove 3210 limit the movement position of the moving rod 327, the slide rod 329 and the anti-detachment block 328, so that the anti-detachment block 328 drives the push rod 3211 to move towards or away from the center of the turntable 323 synchronously. The position of the push rod 3211 is adjusted according to the type of production clamp required. After the production of the production clamp is completed, the clamp is ejected. After the position of the top rod 3211 is adjusted, pull the pull block 66 to move the positioning rod 64 out of the positioning sleeve 65, thereby making the placement box 6 unfixed. After the placement box 6 is unfixed, it can be removed and replaced with a corresponding placement box 6. Insert the sliding plate 61 on the placement box 6 into the slide rail 62 of the top plate 11. After insertion, pull the pull block 66 again. After the pull block 66 is pulled, the second spring 67 is stretched and generates a restoring force, pushing the placement box 6 to the middle of the top plate 11 where it cannot move. Then slowly release the pull block 66. Under the action of the restoring force of the second spring 67, the pull block 66 and the positioning rod 64 are reset, so that the positioning rod 64 is inserted into the positioning sleeve 65 to fix the placement box 6. After the pre-production preparations are completed, the metal plate of the wire clamp material to be produced is placed into the placement box 6, and production can begin. When placing the metal plate into the placement box 6, ensure that the push plate 51 is below the placement box 6 to avoid the metal plate falling directly above the support frame 2 and causing misalignment when placing the metal plate in a concentrated manner. After the metal plate is placed, the fourth electric cylinder 5 is activated. The fourth electric cylinder 5 first moves the push plate 51 away from the placement box 6, exposing the bottom of the placement box 6, so that the metal plate falls onto the upper surface of the placement frame 14. Then, it moves the push plate 51 closer to the placement box 6, pushing the metal plate towards the upper center of the square block 12, and blocking the bottom of the placement box 6 again to prevent the metal plate from falling out of the placement box 6. After the metal plate is pushed to the upper center of the square block 12, the first electric cylinder 131 is activated. The first electric cylinder 131 drives the lifting plate 132 and the upper die 13 to descend, and works with the lower die 121 to stamp and bend the metal plate. After stamping and bending, the first electric cylinder 131 drives the lifting plate 132 and the upper die 13 to rise, and the third electric cylinder 31 is activated, which drives the ejector rod 3211 to approach the produced wire clamp, so that the wire clamp can be ejected and fall to the unloading guide plate 15 for collection. After ejection, the third electric cylinder 31 drives the ejector rod 3211 to reset. Repeating the above operation can continuously produce wire clamps. The same equipment can produce different types of wire clamps by changing the upper die 13 and the placement box 6, and adjusting the position of the lower die 121 and the ejector rod 3211. This improves adaptability and versatility.
