Description

Technical Field

[0001] This utility model belongs to the technical field of busbar processing equipment, and in particular relates to an integrated machine for punching, shearing and bending busbars. Background Technology

[0002] In the electrical industry, busbars (mainly copper and aluminum) are core components for current transmission and distribution, and their processing quality and efficiency have a profound impact on the overall performance, safety, and reliability of electrical equipment. With the continuous growth in electricity demand and the increasing complexity of electrical equipment, higher demands are being placed on busbar processing technology. However, traditional busbar processing methods typically employ multiple independent machines to complete processes such as feeding, shearing, punching, and bending. This approach not only occupies a large area and has low production efficiency, but also makes it difficult to effectively guarantee processing quality. Especially in the punching process, existing equipment generally uses a clamping method on the punched surface, resulting in indentations on the sides of the copper busbar, which in turn affects the electrical performance and safety of the busbar and causes sharp-angle discharge. Therefore, developing a highly integrated busbar punching, shearing, and bending machine has become a pressing technical challenge for the current electrical industry.

[0003] Current status and existing problems of busbar processing:

[0004] Currently, busbar processing mainly relies on multi-station processing equipment. This equipment consists of multiple independent modules, including feeding devices, punching devices, shearing devices, and bending devices. Each module requires independent operation and control, which not only increases the complexity and floor space of the equipment but also reduces production efficiency. Furthermore, the lack of close coordination between the modules often leads to decreased processing accuracy and consistency, affecting the overall quality of the busbars.

[0005] In the punching process, existing busbar processing equipment typically uses clamping to fix the busbar to the worktable for punching. However, this clamping method has significant drawbacks: the indentations created by the clamps on the side of the copper busbar not only affect its aesthetics, but more importantly, the sharp corners formed by these indentations can easily trigger angular discharge, severely reducing the busbar's insulation performance and safety. In high-voltage, high-current applications, this angular discharge can lead to equipment failure or even safety accidents, posing a serious threat to the stable operation of electrical equipment.

[0006] Limitations of existing technology:

[0007] While existing technologies have proposed some solutions to the problems in busbar machining, they often only address partial issues and cannot fundamentally change the current situation of low machining efficiency, large footprint, and difficulty in guaranteeing machining quality. For example, some equipment attempts to reduce indentation by optimizing clamp design, but the results are not ideal; other equipment increases production efficiency by increasing automation, but often at the cost of machining accuracy and flexibility. These limitations make existing technologies inadequate for meeting the complex and high-precision requirements of busbar machining.

[0008] To address the problems existing in the prior art, this utility model proposes a highly integrated busbar punching, shearing, and bending machine. This equipment integrates multiple processes such as feeding, punching, shearing, and bending into a compact machine body, achieving seamless connection and coordinated operation between each process through a high-precision mechanical transmission system. This design not only significantly reduces the equipment's footprint and complexity but also improves production efficiency and processing accuracy. Utility Model Content

The following is a detailed summary of the overall technical effects of this integrated machine:

[0031] I. High integration and automation

[0032] This invention highly integrates multiple processes such as busbar processing, including feeding, punching, cutting, and bending, into a single machine, significantly reducing floor space and complexity while improving production efficiency and space utilization. This highly integrated design makes the entire processing flow more compact and streamlined, avoiding the problems of low production efficiency and high logistics costs caused by the dispersed processes in traditional multi-station processing equipment.

[0033] Meanwhile, this integrated machine realizes the entire process from busbar feeding to finished product output.

This highly automated production method not only improves production efficiency but also reduces labor costs and enhances product quality and consistency.

[0034] II. High-precision machining

[0035] In terms of processing precision, this integrated machine also performs excellently. The feeding assembly, through the precise design of components such as idlers, clamping conveyors, and support plates, ensures the stability and accuracy of the busbar during the conveying process. The rolling of the idlers reduces friction between the busbar and the base plate, improving conveying efficiency; the clamping conveyor firmly clamps the busbar, preventing it from shifting or loosening during conveying.

[0036] The punching and cutting assembly integrates multiple functions such as punching, cutting, and embossing. Through the coordinated action of components such as high-precision linear guides, servo motors, and lead screw and nut pairs, it achieves precise machining of the busbars. The high precision and responsiveness of the servo motors ensure the accuracy of the punching and cutting positions; the lead screw and nut pairs convert rotary motion into linear motion, enabling precise positioning and control of the die. This high-precision machining method guarantees the consistency and high quality of the busbar machining.

[0037] The bending assembly also employs high-precision design and control technology. The coordination of the moving rotary bending device and the auxiliary rotary support bending device, along with the precise control of the servo motor and reduction gear pair, enables precise bending and forming of the busbar. By adjusting the speed and direction of the servo motor, the bending angle and speed can be precisely controlled; the reduction gear pair plays a role in reducing speed and increasing torque, improving the stability and reliability of the bending force.

[0038] III. Stability and Reliability

[0039] The stability and reliability of equipment are among the most important indicators for evaluating its performance. This integrated machine adopts a robust frame structure, ensuring stable installation and precise alignment of all components. The frame's strength and rigidity have been optimized to withstand various forces and vibrations during processing, guaranteeing the overall stability and reliability of the equipment.

[0040] As a key component of the equipment, the clamping drive also employs a highly stable design. Efficient power sources such as servo motors, pneumatic cylinders, or hydraulic cylinders provide stable clamping force; a precise transmission mechanism ensures uniform distribution and accurate control of the clamping force. This design effectively prevents the busbar from shifting or loosening during processing, improving the stability and reliability of the machining process.

[0041] In addition, the equipment is equipped with a variety of safety protection measures, such as protective doors and protective covers, which further enhance the safety and reliability of the equipment. These measures can effectively prevent operators from being injured during processing, while also protecting the equipment itself from damage.

[0042] IV. Flexibility and Adaptability

[0043] This utility model's integrated machine is designed with flexibility and adaptability in mind. The equipment can be flexibly adjusted and optimized to meet the processing needs of busbars of different specifications and shapes. For example, by changing molds of different specifications and adjusting parameters, it can process busbars of different thicknesses and materials; by adjusting the position and angle of the clamping and conveying device and the bending assembly, it can process busbars of different shapes and sizes.

[0044] This flexibility and adaptability enable the integrated machine to be widely used in various electrical equipment and power systems, meeting diverse processing needs. At the same time, it saves enterprises on equipment investment costs, maintenance costs, and labor costs, while improving production efficiency and economic benefits.

[0045] In summary, this utility model, a busbar punching, shearing, and bending integrated machine, achieves efficient, high-quality, and low-cost busbar processing through technological optimization and innovation in areas such as high integration, automation, high-precision machining, stability and reliability, flexibility, and adaptability. This integrated machine not only improves production efficiency and quality, bringing significant economic and social benefits to enterprises, but also has broad application prospects and market value in the electrical industry.

[0065] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0066] Please see Figures 1 to 5A busbar punching, shearing, and bending integrated machine includes a frame 1, which serves as the supporting structure for the entire machine. The frame ensures the stable installation and precise alignment of each component, providing a solid foundation for the entire processing. The upper surface of the frame 1 is Y-shaped, but not limited to this shape. The Y-shaped frame includes a feeding assembly mounting area 101; a punching and cutting assembly mounting area 102 in the middle; and two branches of the Y-shape serving as bending assembly mounting areas 103. By designing the frame surface into a Y-shape and installing assemblies with different functions in different areas, modular partitioning is achieved. This design allows each assembly to have its own independent space, avoiding mutual interference and improving the overall layout rationality. The Y-shaped design makes the frame more compact in space, effectively utilizing space resources. This compactness not only reduces the overall volume of the mold but also makes operation and maintenance more convenient. The rational layout of the feeding assembly, punching and cutting assembly, and bending assembly on the Y-shaped frame makes the production process smoother. Material enters from the loading area, passes through the punching and cutting area, and finally enters the bending area. The entire production process is smooth and unobstructed, improving production efficiency. The modular design allows each assembly to be replaced and maintained independently, significantly reducing mold changeover time. The Y-shaped design makes it easier for operators to access and operate each assembly. Whether loading, punching, cutting, or bending, operators can work from a relatively comfortable and convenient position. Each assembly has its own independent space, making maintenance and upkeep more convenient. Maintenance personnel can easily access each assembly to inspect, repair, and replace parts.

[0067] The feeding assembly 2 is used to transport unprocessed busbars. This assembly efficiently and accurately transports the unprocessed busbars to subsequent processing stages, improving production efficiency and processing precision. The punching and cutting assembly 3 is used to punch and cut the busbars transported by the feeding assembly to a fixed length. This punching and bending assembly is adjacent to the discharge port of the feeding assembly. This assembly integrates punching and cutting functions, enabling the punching and cutting of busbars in a single operation, reducing processing steps and time, and improving production efficiency. Simultaneously, precise punching and cutting ensure the consistency and high quality of busbar processing. This function allows the integrated machine to complete the entire processing process from raw materials to finished products, improving production convenience and efficiency. The bending assembly 4 is used to bend the punched busbars at a designed angle. This bending assembly can bend the punched busbars at a predetermined angle according to design requirements, achieving precise forming of the busbars. This function enables the all-in-one machine to complete the entire processing from raw materials to finished products, improving the convenience and efficiency of production; the above-mentioned feeding assembly, punching and cutting assembly and bending assembly are fixedly installed on the frame panel of the machine frame, wherein the punching and cutting assembly is located between the feeding assembly and the bending assembly.

[0068] By integrating multiple processes such as feeding, punching, cutting, and bending into a single machine, this all-in-one machine achieves a high degree of integration and automation in busbar processing. This design not only reduces the machine's footprint and complexity but also significantly improves production efficiency and processing accuracy. Furthermore, the all-in-one machine offers advantages such as ease of operation and maintenance, significantly reducing user costs and maintenance burdens. Therefore, this all-in-one machine has broad application prospects and market value in the electrical industry.

[0069] For further recommendations, please refer to [link / reference]. Figures 6 to 9 The feeding assembly 2 includes a feeding base plate 21, which serves as the basic structure of the feeding assembly and provides a stable support platform to ensure the stability of the busbar during transportation. Several idlers 22 are provided on the feeding base plate along the transportation direction. Through their installation on idler frames, they effectively support and guide the busbar forward. The rolling of the idlers reduces friction between the busbar and the base plate, improving transportation efficiency. The idlers are mounted on idler frames 23, which are in turn mounted on the feeding base plate. Busbar clamping and conveying devices 24 are provided on both sides of the idlers to clamp the two non-punched surfaces of the busbar and transport it towards the punching and cutting assembly. These devices clamp the two non-punched surfaces of the busbar, ensuring that it does not deviate from the predetermined trajectory during transportation and is stably transported towards the punching and cutting assembly. This design improves the accuracy and reliability of the conveying process, while preventing damage to the surface of the busbar punched with a metal rod. It also avoids the sharp-angle discharge phenomenon caused by the punching process, which may lead to equipment failure or even safety accidents. A support plate 25 is provided between adjacent idlers. The idlers are higher than the upper surface of the support plate, which can provide additional support between the idlers to ensure that the busbar will not sag or deform due to gravity during the conveying process, thus maintaining the flatness and processing quality of the busbar.

[0070] More preferably, the busbar clamping and conveying device 24 includes a main clamping and feeding mechanism 240 and a secondary clamping mechanism 250 arranged opposite to each other. The main clamping and feeding mechanism and the secondary clamping mechanism are used to clamp the busbar while conveying it towards the punching and cutting assembly. Through the cooperation of the main clamping and feeding mechanism and the secondary clamping mechanism, the busbar clamping and conveying device achieves efficient and stable clamping and conveying of the busbar. This design not only improves processing efficiency but also ensures the accuracy and consistency of the busbar during processing, providing a strong guarantee for the high-performance operation of the entire integrated machine.

[0071] Preferably, the main clamping and feeding mechanism 240 and the auxiliary clamping mechanism 250 are mounted on two parallel linear guides 26 perpendicular to the busbar conveying direction. This design ensures that the main clamping and feeding mechanism and the auxiliary clamping mechanism maintain stable linear motion when clamping and conveying the busbar, avoiding busbar position deviation caused by mechanism offset. The high precision and stability of the linear guides provide a strong guarantee for the accurate processing of the busbar. The linear guides mentioned in this application can be T-shaped guides, dovetail guides, optical axis guides, or finished linear guide assembly. Both the main clamping and feeding mechanism and the auxiliary clamping mechanism are connected to a clamping drive device 27 that drives the relative movement of the main clamping and feeding mechanism and the auxiliary clamping mechanism. The clamping drive device enables the two to move relative to each other, realizing the clamping and release of the busbar. The power and control precision provided by the clamping drive device ensure that the busbar can be firmly clamped during processing and accurately released when needed, improving processing efficiency and accuracy.

[0072] Further preferably, the clamping drive device 27 includes a clamping servo motor 271 and a lead screw and nut assembly 272; the servo motor, as a power source, features high precision, high responsiveness, and low noise. In the clamping drive device, the servo motor can provide stable and controllable power output, ensuring that the main clamping feeding mechanism and the auxiliary clamping mechanism can achieve the required clamping force when clamping the busbar, while ensuring the speed and accuracy of the action. The lead screw 2720 of the lead screw and nut assembly is a lead screw with positive and negative threads at both ends; the lead screw and nut 2721 of the lead screw and nut assembly connects the main clamping feeding mechanism and the auxiliary clamping mechanism; the clamping servo motor is connected to one end of the lead screw and drives the lead screw to rotate, providing clamping force to the main clamping feeding mechanism and the auxiliary clamping mechanism. The lead screw and nut assembly is a mechanical device that converts rotary motion into linear motion. In this device, the two ends of the lead screw are provided with positive and negative threads. This allows the main clamping and feeding mechanism and the secondary clamping mechanism connected to the lead screw nut to move simultaneously but in opposite directions when the lead screw rotates, thereby clamping and releasing the busbar. The high precision and stability of the lead screw and nut pair ensure the accuracy and reliability of the clamping action.

[0073] Preferably, the clamping drive device 27 employs a pneumatic cylinder or a hydraulic cylinder, which connects the main clamping and feeding mechanism and the auxiliary clamping mechanism, providing the clamping force for the main clamping and feeding mechanism and the auxiliary clamping mechanism to clamp the busbar. In this invention, the clamping drive device can employ a screw and nut pair, or a pneumatic cylinder or a hydraulic cylinder design, simplifying the device structure. Furthermore, by directly connecting the main clamping and feeding mechanism and the auxiliary clamping mechanism through the pneumatic or hydraulic cylinder, faster and more accurate clamping actions are achieved. The powerful and stable clamping force provided by the pneumatic or hydraulic cylinder ensures the stability of the busbar during processing, thereby improving overall processing efficiency and accuracy.

[0074] Further preferably, the main clamping and feeding mechanism 240 includes a main clamping moving plate 241. As the main load-bearing component of the main clamping and feeding mechanism, the main clamping moving plate is designed to ensure stability during clamping and conveying. Through cooperation with the linear guide rail and the main linear slider, the main clamping moving plate can move smoothly along a predetermined trajectory, providing a foundation for the precise conveying of the busbars. Main linear sliders 242, which cooperate with the linear guide rail, are installed on both sides below the main clamping moving plate 241. The tight cooperation between the main linear sliders and the linear guide rail ensures the straightness and stability of the main clamping moving plate during movement. This design reduces friction and vibration during movement, improving the accuracy and efficiency of busbar conveying. A main clamping assembly 243 is installed above the main clamping moving plate. The main clamping assembly is the core part of the main clamping and feeding mechanism, designed to firmly clamp the busbars. The main clamping assembly 243 includes N main clamping wheels 2430 located below the main clamping moving plate near the idler roller, along the busbar conveying direction, via axles. N is an integer greater than or equal to 2. The multiple clamping wheels (at least two) increase the contact area and clamping force with the busbar, improving clamping stability and reliability. Simultaneously, the multiple clamping wheels help disperse impact forces during busbar conveying, protecting the busbar from damage. Through the synergistic action of the multiple clamping wheels, the main clamping assembly can evenly distribute the clamping force, ensuring the busbar does not loosen or shift during conveying. Each main clamping wheel is connected to a drive component 2431, which is connected to a feeding servo motor 2432. The drive component transmits the power from the feeding servo motor to the main clamping wheels, achieving precise control of the clamping force. The high precision and responsiveness of the feeding servo motor ensure the speed and accuracy of the main clamping wheels when clamping and releasing the busbar.

[0075] In summary, the main clamping and feeding mechanism, through precise mechanical design and servo motor control, achieves efficient and stable clamping and conveying of the busbars. This technical solution not only improves the accuracy and efficiency of busbar conveying but also ensures the stability and reliability of the busbars during processing. The design of multiple main clamping wheels increases clamping force and stability, while the cooperation between the linear slider and the linear guide rail ensures the linearity and smoothness of movement. This technical solution provides a reliable guarantee for subsequent punching and cutting processes, improving overall production efficiency.

[0076] In a further preferred embodiment, the N main clamping wheels are connected to the feeding servo motor through a driving component; that is, the N main clamping wheels (N is an integer greater than or equal to 2) are connected to the feeding servo motor through a unified driving component.

[0077] This design brings about the following significant technical benefits:

[0078] Simplified Structure: Connecting multiple main clamping wheels with a single drive component greatly simplifies the mechanical structure, reducing the number of parts and assembly complexity. This not only lowers manufacturing costs but also improves the maintainability and reliability of the equipment.

[0079] Synchronous clamping: Since all the main clamping wheels are driven by the same drive component, they can clamp and release synchronously. This ensures that the busbar is subjected to uniform force during clamping, avoiding offset or deformation caused by inconsistent clamping force.

[0080] Precise Control: The feeding servo motor is renowned for its high precision and responsiveness. It transmits power to the drive components, thereby controlling the clamping force and movement speed of the main clamping rollers. This precise control method improves the accuracy and efficiency of busbar conveying.

[0081] Energy saving: Using a single drive component and servo motor to drive multiple main clamping rollers is more energy-efficient than a design where each clamping roller has its own independent drive source. This helps reduce equipment operating costs and meets the energy-saving and environmental protection requirements of modern industry.

[0082] Improved stability: A unified drive component and servo motor control system reduce errors and vibrations in mechanical transmission, improving the stability of the entire main clamping and feeding mechanism. This helps ensure precise positioning and stable transport of the busbars during processing.

[0083] More preferably, the driving component is a synchronous toothed belt, which is connected to the output gear of the feeding servo motor; a gear 2433 that meshes with the synchronous toothed belt is mounted on the axle of the main clamping wheel above the main clamping moving plate; and synchronous toothed belt pressure rollers 2434 are provided between adjacent gears. Using a synchronous toothed belt as the driving component, connecting the output gear of the feeding servo motor with the gear on the main clamping wheel, achieves precise power transmission. The tight fit between the synchronous toothed belt and the gear ensures the synchronicity and accuracy of the main clamping wheel when clamping and conveying the busbar. The synchronous toothed belt pressure rollers provided between adjacent gears further enhance the stability and reliability of the transmission.

[0084] Furthermore, preferred options for the drive components include chains or gears, which offer greater flexibility and adaptability to meet the needs of different application scenarios. Overall, this technology, through precise mechanical design and efficient transmission, enhances the performance and stability of the main clamping and feeding mechanism, ensuring efficient busbar processing.

[0085] Further preferably, the secondary clamping mechanism 250 includes a secondary clamping moving plate 251. Secondary linear sliders 252, which cooperate with linear guide rails, are installed on both sides below the secondary clamping moving plate. The secondary clamping moving plate 251 is installed above the secondary clamping moving plate. N secondary clamping wheels 253, located along the busbar conveying direction and via axles, are arranged below the secondary clamping moving plate near the idler roller side. N is an integer greater than or equal to 2. This is mainly reflected in its precise structural design and efficient clamping function. Through the ingenious cooperation between the secondary clamping moving plate, the linear guide rail, and the secondary linear sliders, this mechanism achieves stable, linear movement in the busbar conveying direction, providing a strong guarantee for the precise positioning of the busbar. The secondary clamping moving plate installed above the secondary clamping moving plate, and the N secondary clamping wheels (N≥2) arranged below it along the busbar conveying direction, together constitute a powerful clamping system. This design not only increases the contact area with the busbar but also ensures a uniform distribution of clamping force, thereby effectively preventing the busbar from loosening or shifting during conveying. The coordinated action of multiple secondary clamping wheels further enhances the stability and reliability of clamping, creating favorable conditions for subsequent machining operations. In summary, this secondary clamping mechanism, through its precise structural design and efficient clamping function, provides a solid guarantee for the efficient and stable machining of busbars.

[0086] More preferably, a gap maintaining component 28 is provided between the main clamping moving plate and the secondary clamping moving plate.

[0087] For further recommendations, please refer to [link / reference]. Figure 10 The spacing maintaining assembly 28 includes a maintaining rod 280, which is located above the idler roller 22, leaving space between it and the idler roller for the busbar to pass through. One end of the maintaining rod is connected to a main clamping moving plate or a secondary clamping moving plate via a shear pin 281. The corresponding secondary clamping moving plate and the main clamping moving plate are provided with guide holes 282. A positioning block 283 is provided perpendicularly to the radial direction of the guide hole to abut the maintaining rod and keep it relatively stationary. The upper part of the positioning block is connected to a positioning cylinder 284 or a hydraulic cylinder that drives the positioning block to move up and down. Its technical effects are significant. First, the ingenious design between the maintaining rod and the idler roller provides a stable passage space for the busbar, ensuring the smoothness and accuracy of the busbar during transport. Second, the connection of one end of the maintaining rod to the main clamping moving plate or the secondary clamping moving plate via a shear pin ensures both a strong connection and facilitates quick replacement or adjustment when needed. Furthermore, the guide holes and positioning blocks allow the maintaining rod to remain relatively stationary in the radial direction, further improving the stability of the busbar transport. Finally, the introduction of a positioning cylinder or hydraulic cylinder enables precise control of the positioning block, allowing for flexible adjustment of the position and spacing of the retaining rod as needed. In summary, this spacing retention assembly, through its precise design and efficient function, provides a more stable and reliable guarantee for busbar machining.

[0088] Building upon the above, the shear pin plays a crucial role. It not only serves as a connector between the retaining rod and the main or secondary clamping moving plate, but also automatically shears at the shear pin point under excessive force, effectively protecting the clamping servo motor from damage. This design cleverly utilizes the mechanical properties of the shear pin; when the external force exceeds its bearing limit, the shear pin breaks rapidly, cutting off the excessive force transmitted to the servo motor and ensuring its lifespan remains unaffected. Therefore, the addition of the shear pin not only improves the safety and reliability of the entire clamping system but also provides a strong guarantee for the long-term stable operation of the servo motor.

This design provides a stable mounting base for the entire assembly through the limit mounting plate. The vertical mounting of the clamping cylinder and the clamping plate connected to its lower end allow for flexible adjustment of the clamping force on the busbar as needed, ensuring that the busbar remains flat during transport. The busbar clamping roller at the lower end of the clamping plate further enhances the clamping effect while reducing frictional damage to the busbar.

[0090] Furthermore, the cooperation between the guide sleeve and the guide post on the clamping plate makes the clamping plate more stable during its up-and-down movement, avoiding uneven clamping force caused by vibration or displacement. The connecting block connects the upper end of the guide post to the limit mounting plate, forming a stable connection for the entire assembly and ensuring the reliability and durability of the busbar upper limit assembly.

[0097] Preferably, protective doors 322 are movably installed on the bases on both sides of the supporting upright plate. The main technical benefit of the protective doors movably installed on the bases on both sides of the supporting upright plate is safety protection. The protective doors can effectively isolate the dangerous area during the punching and cutting process, preventing operators from accidentally entering or being injured by flying debris, while also reducing noise and dust leakage and improving the working environment.
