Description

Technical Field

[0001] This application relates to the field of stamping equipment technology, and in particular to a punching structure for a copper busbar. Background Technology

[0002] Currently, copper busbars are high-current conductive products suitable for electrical engineering such as high and low voltage electrical appliances, switch contacts, power distribution equipment, and busbar trunking. They are also widely used in ultra-high current electrolytic smelting projects such as metal smelting, electroplating, and chemical caustic soda production. Electrical copper busbars have advantages such as low resistivity and high bendability.

[0003] Regarding the aforementioned technologies, most existing punching structures suffer from the drawback of being unable to expand the holes, which significantly increases the limitations of the device. Because the hole specifications are fixed, it is difficult to achieve diversified expansion, which greatly restricts the applicability of the device. If it can be equipped with multi-specification hole processing functions, diversified punching operations can be carried out on copper busbars. This will greatly improve the flexibility and expandability of the device, enabling it to better adapt to the processing needs of different scenarios. Utility Model Content

[0004] The purpose of this application is to provide a punching structure for copper busbars, which has the advantages of high flexibility in punching holes of various specifications, and solves the problems mentioned in the background art.

[0005] The copper busbar punching structure provided in this application adopts the following technical solution: it includes a frame, three bases, a rotating mechanism, a multi-specification hole mechanism, a punching mechanism, several stamping columns, a positioning mechanism, and a waste collection mechanism. The rotating mechanism includes a drive motor fixedly mounted on the top of the base via a mounting plate. Bearings are fixedly connected inside the two bases. A conversion shaft is rotatably connected inside the two bearings. The top end of the conversion shaft is fixedly connected to the output shaft of the drive motor. A fixed plate and a hole position plate are fixedly connected to the surface of the conversion shaft.

[0006] The multi-specification hole mechanism includes several circular holes formed on the top of the hole plate. The size of the circular holes is different. The bottom ends of the several stamping columns are fixedly connected to stamping heads. The thickness of the stamping heads is different. The stamping heads are adapted to the circular holes.

[0007] By adopting the above technical solution, and by setting up a rotating mechanism and a multi-specification hole mechanism, the drive motor can drive the conversion shaft to rotate, and the hole position plate and fixed plate on the subsequent conversion shaft will rotate accordingly. This achieves the purpose of aligning the circular holes of different specifications with the punching head to the copper busbar to be punched, realizing the ability to flexibly switch between different specifications of punching combinations according to actual needs, without the need for frequent mold changes. This significantly improves the versatility and production efficiency of the equipment and is suitable for processing various specifications of copper busbars.

[0008] Preferably, a guide rail is fixedly connected to the top of the frame, and three bases are fixedly connected to the top and bottom of the guide rail to the top of the frame.

[0009] By adopting the above technical solution and setting guide rails and bases, the equipment can form a modular spatial layout. Since the guide rails are linear support structures, the bases can be arranged in an orderly manner in the horizontal direction, avoiding the space waste caused by traditional decentralized installation. This compact design not only reduces the equipment's footprint, but also provides a basis for multi-station collaborative processing, enabling operators to efficiently complete the punching tasks of copper busbars of different specifications in a limited space.

[0010] Preferably, the punching mechanism includes a hydraulic cylinder fixedly installed on the top of the base, a pressing rod fixedly installed inside the hydraulic cylinder, a pressing block fixedly connected to the bottom end of the pressing rod, a plurality of fixing blocks fixedly connected to the surface of the fixing plate, a punching column slidably connected inside the plurality of fixing blocks, a pressing head fixedly connected to the top of the plurality of punching columns, a spring sleeved on the surface of the plurality of punching columns, and the pressing block overlapping the top of the pressing head.

[0011] By adopting the above technical solution and setting a punching mechanism, the hydraulic cylinder controls the internal hydraulic oil to push the pressing rod downward. Subsequently, the pressing rod drives the pressing block at the bottom to descend synchronously. During the descent of the pressing block, it contacts the top of multiple pressing heads and applies downward pressure. After being subjected to force, the pressing head pushes the stamping column to slide downward in the fixed block. Subsequently, the stamping head at the bottom of the stamping column contacts the copper busbar and applies impact force to complete the punching action. After punching is completed, the hydraulic cylinder drives the pressing rod to rise, the pressing block disengages from the pressing head, the spring releases elastic potential energy, and pushes the stamping column upward to reset to the initial position, thus achieving the purpose of punching the copper busbar.

[0012] Preferably, the positioning mechanism includes a support frame fixedly connected to the bottom of the base, an electric push rod fixedly installed inside the support frame, and a clamping plate fixedly connected to the bottom end of the electric push rod.

[0013] By adopting the above technical solution and setting up a positioning mechanism, after the copper busbar is placed on top of the hole positioning plate, the electric push rod is activated to extend it and push the clamping plate downward to clamp the copper busbar together with the top of the hole positioning plate. Through this precise positioning and stable clamping, the accuracy of the punching position is ensured, product quality is improved, and the scrap rate is reduced.

[0014] Preferably, the waste collection mechanism includes a waste box fixedly connected to the surface of the conversion shaft, a magnetic layer is provided on the side of the waste box, and a sealing plate is overlapped on the side of the magnetic layer, the sealing plate being made of ferrous material.

[0015] By adopting the above technical solution and setting up a waste collection mechanism, the copper scrap punched down during the punching process will fall directly into the waste box. Due to the magnetic attraction between the magnetic layer on the side of the waste box and the ferrous sealing plate, the sealing plate can fit tightly against the side of the waste box, effectively preventing waste leakage. When the waste in the waste box accumulates to a certain level, the infrared sensor on the top of the waste box detects the waste height and triggers the alarm light to remind the operator to clean it up in time. This design realizes automatic collection and convenient handling of waste, maintains a clean working environment, reduces the workload of manual cleaning, and also facilitates centralized recycling of waste, reducing production costs.

[0016] Preferably, an alarm light is fixedly installed on the surface of the waste box, and an infrared sensor is provided on the top of the waste box.

[0017] By adopting the above technical solution, alarm lights are set to remind personnel to clean up waste, and infrared sensors are set to monitor the accumulation height of waste.

[0018] Preferably, the bottom of the frame is fixedly connected to four support legs, and the bottom of each of the four support legs is fixedly connected to a silicone block.

[0019] By adopting the above technical solution and setting up support legs and silicone blocks, stable support can be provided for the entire equipment. Because silicone blocks have good elasticity and cushioning performance, they can effectively absorb the vibration generated by the equipment during operation, reduce the impact of vibration on processing accuracy, and also reduce the noise transmission between the equipment and the ground.

[0020] Preferably, rubber pads are provided on the top of the fixing plate and the bottom of the clamping plate.

[0021] By adopting the above technical solution, the rubber pad enhances the friction on the copper busbar surface, preventing the copper busbar from sliding during the punching process and avoiding scratches on the copper busbar surface.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This copper busbar punching structure, through the setting of a rotating mechanism and a multi-specification hole mechanism, enables the drive motor to drive the conversion shaft to rotate, and the hole position plate and fixed plate on the subsequent conversion shaft to rotate accordingly, so as to align the circular holes of different specifications with the punching head to the position to be punched on the copper busbar. It realizes the flexible switching of different specifications of punching combinations according to actual needs, without the need for frequent mold changes, which significantly improves the versatility and production efficiency of the equipment and is suitable for the processing needs of copper busbars of various specifications.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: A punching structure for a copper busbar, referring to... Figure 1 , Figure 2 and Figure 3 It includes a frame 1, three bases 3, a rotating mechanism 4, a multi-specification hole mechanism 5, a punching mechanism 6, several stamping columns 606, a positioning mechanism 7, and a waste collection mechanism 8. The rotating mechanism 4 includes a drive motor 401 fixedly mounted on the top of the base 3 via a mounting plate. Bearings 402 are fixedly connected inside the two bases 3. A conversion shaft 403 is rotatably connected inside the two bearings 402. The top end of the conversion shaft 403 is fixedly connected to the output shaft of the drive motor 401. A fixed plate 404 and a hole plate 405 are fixedly connected to the surface of the conversion shaft 403.

[0033] The multi-specification hole mechanism 5 includes several circular holes 501 formed on the top of the hole positioning plate 405. The circular holes 501 are of different sizes. The bottom ends of several stamping columns 606 are fixedly connected to stamping heads 502, which are of different thicknesses. The stamping heads 502 are adapted to the circular holes 501. By setting up the rotating mechanism 4 and the multi-specification hole mechanism 5, the drive motor 401 can drive the conversion shaft 403 to rotate. Subsequently, the hole positioning plate 405 and the fixed plate 404 on the conversion shaft 403 rotate accordingly, so as to align the circular holes 501 of different specifications with the stamping heads 502 to the copper busbar to be punched. This achieves the effect of flexibly switching different specifications of punching combinations according to actual needs, without the need for frequent mold changes, which significantly improves the versatility and production efficiency of the equipment and is suitable for the processing needs of copper busbars of various specifications.

[0034] Please see Figure 1 , Figure 2 and Figure 4 The top of the frame 1 is fixedly connected to a guide rail 2. The top and bottom ends of the guide rail 2 are fixedly connected to three bases 3 on the top of the frame 1. By setting the guide rail 2 and bases 3, the equipment can form a modular spatial layout. Because the guide rail 2 acts as a linear support structure, the bases 3 can be arranged orderly in the horizontal direction, avoiding the space waste caused by traditional distributed installation. This compact design not only reduces the equipment's footprint but also provides a foundation for multi-station collaborative processing, enabling operators to efficiently complete the punching task of copper busbars of different specifications within a limited space. The punching mechanism 6 includes a hydraulic cylinder 601 fixedly installed on the top of the base 3. A pressing rod 602 is fixedly installed inside the hydraulic cylinder 601. A pressing block 603 is fixedly connected to the bottom end of the pressing rod 602. Several fixing blocks 604 are fixedly connected to the surface of the fixing plate 404. A punching column 606 is slidably connected inside each of the fixing blocks 604. Each of the 06 components has a fixed pressing head 605 at its top. A spring 607 is fitted onto the surface of each of the several pressing columns 606. A pressing block 603 overlaps the top of the pressing head 605. By setting a punching mechanism 6, the hydraulic cylinder 601 controls the internal hydraulic oil to push the pressing rod 602 downwards. Subsequently, the pressing rod 602 drives the pressing block 603 at its bottom to descend synchronously. During the descent, the pressing block 603 contacts the tops of multiple pressing heads 605 and applies downward pressure. After being subjected to force, the pressing head 605 pushes the pressing column 606 to slide downwards within the fixed block 604. The pressing head 502 at the bottom of the subsequent pressing column 606 contacts the copper busbar and applies impact force, completing the punching action. After punching, the hydraulic cylinder 601 drives the pressing rod 602 upwards, the pressing block 603 disengages from the pressing head 605, and the spring 607 releases its elastic potential energy, pushing the pressing column 606 upwards to its initial position, thus achieving the purpose of punching the copper busbar.

[0035] Please see Figure 1 andFigure 5 The positioning mechanism 7 includes a support frame 701 fixedly connected to the bottom of the base 3. An electric push rod 702 is fixedly installed inside the support frame 701. A clamping plate 703 is fixedly connected to the bottom end of the electric push rod 702. By setting the positioning mechanism 7, when the copper busbar is placed on top of the hole positioning plate 405, the electric push rod 702 is activated to extend it, pushing the clamping plate 703 downward to clamp the copper busbar together with the top of the hole positioning plate 405. Through this precise positioning and stable clamping, the accuracy of the punching position is ensured, product quality is improved, and the scrap rate is reduced. The waste collection mechanism 8 includes a waste box 801 fixedly connected to the surface of the conversion shaft 403. A magnetic layer 802 is provided on the side of the waste box 801, and a sealing plate 803 overlaps the side of the magnetic layer 802. Material 03 is made of ferrous material. By setting up a waste collection mechanism 8, the copper scrap punched down during the punching process will fall directly into the waste box 801. Due to the magnetic attraction between the magnetic layer 802 on the side of the waste box 801 and the ferrous material sealing plate 803, the sealing plate 803 can fit tightly against the side of the waste box 801, effectively preventing waste leakage. When the waste in the waste box 801 accumulates to a certain level, the infrared sensor 10 on the top of the waste box 801 detects the waste height and triggers the alarm light 9 to send a signal, reminding the operator to clean it up in time. This design realizes automatic collection and convenient handling of waste, keeps the working environment clean, reduces the workload of manual cleaning, and also facilitates centralized recycling of waste, reducing production costs.

[0036] Please see Figure 1 and Figure 3 An alarm light 9 is fixedly installed on the surface of the waste box 801, and an infrared sensor 10 is installed on the top of the waste box 801. The alarm light 9 serves to remind personnel to clean up the waste, and the infrared sensor 10 serves to monitor the accumulation height of the waste. Four support legs 11 are fixedly connected to the bottom of the frame 1, and silicone blocks 12 are fixedly connected to the bottom of each of the four support legs 11. The support legs 11 and silicone blocks 12 provide stable support for the entire equipment. Because the silicone blocks 12 have good elasticity and cushioning performance, they can effectively absorb the vibration generated by the equipment during operation, reduce the impact of vibration on processing accuracy, and also reduce the noise transmission between the equipment and the ground. Rubber pads 13 are provided on the top of the fixed plate 404 and the bottom of the clamping plate 703. The rubber pads 13 enhance the friction on the surface of the copper busbar, prevent the copper busbar from sliding during punching, and also avoid scratching the surface of the copper busbar.

[0037] The implementation principle of this application embodiment is as follows: First, the operator places the copper busbar to be processed on the top of the hole position plate 405 in the area of ​​the clamping plate 703, ensuring that the position of the copper busbar to be punched is roughly aligned with the area of ​​the hole position plate 405.

[0038] Then, the positioning mechanism 7 is activated, the electric push rod 702 in the bottom support frame 701 of the base 3 extends, and pushes the clamping plate 703 to move downward, clamping the copper busbar together with the top of the hole plate 405. The rubber pad 13 at the top of the hole plate 405 and the bottom of the clamping plate 703 increases the friction to prevent the copper busbar from sliding and avoids scratching the surface of the copper busbar.

[0039] Then, according to the required punching specifications of the copper busbar, the position of the hole position plate 405 is adjusted by the rotating mechanism 4, the drive motor 401 is started, and its output shaft drives the conversion shaft 403 to rotate. The fixed plate 404 on the surface of the conversion shaft 403 rotates synchronously with the hole position plate 405, and rotates the corresponding circular hole 501 on the hole position plate 405 to the position of the copper busbar to be punched, so as to ensure that the circular hole 501 is precisely matched with the subsequent punching head 502.

[0040] Afterwards, the punching mechanism 6 is activated to perform the punching operation. The hydraulic cylinder 601 at the top of the base 3 drives the pressing rod 602 to move downward. The pressing block 603 at the bottom of the pressing rod 602 descends synchronously and contacts multiple pressing heads 605, applying downward pressure. The pressing heads 605 push the punching column 606 to slide downward in the fixed block 604. The punching head 502 at the bottom of the punching column 606 contacts the copper busbar and applies impact force, which, together with the circular hole 501 on the hole position plate 405, completes the punching operation. During this process, the spring 607 on the surface of the punching column 606 is compressed, absorbing part of the impact force and reducing equipment vibration.

[0041] Subsequently, after punching is completed, hydraulic cylinder 601 drives pressing rod 602 to rise, pressing block 603 disengages from pressing head 605, spring 607 releases elastic potential energy, pushes stamping column 606 upward to reset to the initial position, and the punched copper scrap falls directly into scrap box 801 on the surface of conversion shaft 403. Magnetic layer 802 on the side of scrap box 801 adsorbs ferrous material sealing plate 803 to prevent scrap leakage.

[0042] Finally, as the punching operation continues, the waste material in the waste box 801 gradually accumulates. When the waste material height reaches the set value, the infrared sensor 10 on the top of the waste box 801 detects a signal and triggers the alarm light 9 on the surface to light up, reminding the operator to clean it in time. When cleaning, the waste material can be removed by removing the sealing plate 803. After cleaning, the sealing plate 803 is replaced, and the equipment can continue to carry out the next round of copper busbar punching operation. Throughout the process, the support legs 11 and silicone blocks 12 at the bottom of the frame 1 provide stable support, absorb equipment vibration, and ensure processing accuracy and equipment stability.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
