Description

Technical Field

[0001] The invention belongs to the technical field of busbar processing equipment, and in particular relates to a busbar punching, shearing and bending integrated machine. Background Art

[0002] In the field of electrical industry, busbars (mainly copper and aluminum) are core components for current transmission and distribution. Their processing quality and efficiency have a profound impact on the overall performance, safety and reliability of electrical equipment. With the continuous growth of electricity demand and the increasing complexity of electrical equipment, higher requirements are placed on busbar processing technology. However, the traditional busbar processing method usually uses multiple independent equipment to complete the loading, shearing, punching, bending and other processes respectively. This method not only occupies a large area and has low production efficiency, but also the processing quality is difficult to be effectively guaranteed. Especially in the punching process, the existing equipment generally adopts the method of clamping the punching surface, which causes the clamp to leave an indentation on the side of the copper busbar, which in turn affects the electrical performance and safety of the busbar and discharges at sharp corners. Therefore, the development of a highly integrated busbar punching, shearing and bending machine has become a technical problem that needs to be solved urgently in the current electrical industry.

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

[0004] At present, busbar processing mainly relies on multi-station processing equipment, which 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. At the same time, due to the lack of close coordination between the modules, the processing accuracy and consistency are often reduced, affecting the overall quality of the busbar.

[0005] In the punching process, existing busbar processing equipment usually clamps the punching surface and fixes the busbar on the workbench with a clamp for punching. However, this clamping method has obvious defects: the indentation produced by the clamp on the side of the copper busbar not only affects the aesthetics of the busbar, but more importantly, the sharp corners formed by the indentation can easily cause sharp corner discharge, seriously reducing the insulation performance and safety of the busbar. In high-voltage and high-current application scenarios, this sharp corner discharge phenomenon may cause equipment failure or even safety accidents, posing a serious threat to the stable operation of electrical equipment.

[0006] Limitations of existing technologies:

[0007] Although existing technologies have proposed some solutions to the problems in busbar processing, they can only solve some of the problems and cannot fundamentally change the current situation of low processing efficiency, large floor space, and difficult to ensure processing quality. For example, some equipment attempts to reduce the generation of indentations by optimizing the clamp design, but the effect is not ideal; other equipment increases the degree of automation to improve production efficiency, but often at the expense of processing accuracy and flexibility. These limitations make existing technologies incapable of meeting the complex and high-precision busbar processing requirements.

[0008] In order to solve the problems existing in the prior art, the present invention proposes a highly integrated busbar punching, shearing and bending machine. The equipment integrates multiple processes such as feeding, punching, shearing and bending in a compact body, and realizes seamless connection and coordination between the processes through a high-precision mechanical transmission system. This design not only greatly reduces the floor space and complexity of the equipment, but also improves production efficiency and processing accuracy. Summary of the invention

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

[0031] 1. High degree of integration and automation

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

[0033] At the same time, the all-in-one machine realizes the whole process from busbar loading to finished product output. Through efficient power sources such as servo motors, cylinders or oil cylinders, combined with precise transmission mechanisms and control systems, the equipment can automatically complete busbar clamping, conveying, punching, cutting and bending processes without manual intervention or only a small amount of manual assistance. This highly automated production method not only improves production efficiency, but also reduces labor costs and improves product quality and consistency.

[0034] 2. High-precision machining

[0035] In terms of processing accuracy, the integrated machine of the present invention also performs well. The loading assembly ensures the stability and accuracy of the busbar during the conveying process through the precise design of components such as rollers, clamping conveying devices and supporting plates. The rolling of the rollers reduces the friction between the busbar and the substrate, improving the conveying efficiency; the clamping conveying device can firmly clamp the busbar to prevent it from deflecting or loosening during the conveying process.

[0036] The punching and cutting assembly integrates multiple functions such as punching, cutting and embossing. Through the synergy of high-precision linear guides, servo motors, and lead screw nut pairs, the precise processing of the busbar is achieved. The high precision and responsiveness of the servo motor ensure the accuracy of the punching and cutting positions; the lead screw nut pair converts the rotary motion into linear motion, achieving precise positioning and control of the mold. This high-precision processing method ensures the consistency and high quality of the busbar processing.

[0037] The bending assembly also uses high-precision design and control technology. The coordination of the mobile rotary bending device and the auxiliary rotary support bending device, as well as the precise control of the servo motor and the reduction gear pair, achieves 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 the role of deceleration and torque increase, improving the stability and reliability of the bending force.

[0038] 3. Stability and reliability

[0039] The stability and reliability of equipment is one of the important indicators to measure its performance. The all-in-one machine of the present invention adopts a solid frame structure to ensure the stable installation and precise alignment of various components. The strength and rigidity of the frame are optimized to withstand various forces and vibrations during the processing, ensuring the overall stability and reliability of the equipment.

[0040] As one of the key components of the equipment, the clamping drive device also adopts a high-stability design. High-efficiency power sources such as private motors, cylinders or oil cylinders provide stable clamping force; precise transmission mechanisms ensure uniform distribution and precise control of the clamping force. This design effectively prevents the busbar from shifting or loosening during processing, and improves the stability and reliability of processing.

[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 the processing process, and also protect the equipment itself from damage.

[0042] Flexibility and Adaptability

[0043] The design of the integrated machine of the present invention fully considers the needs of flexibility and adaptability. The equipment can be flexibly adjusted and optimized according to the processing requirements of busbars of different specifications and shapes. For example, by replacing molds of different specifications and adjusting parameters, busbars of different thicknesses and materials can be processed; by adjusting the position and angle of the clamping conveying device and the bending assembly, busbars of different shapes and sizes can be processed.

[0044] This flexibility and adaptability enables the all-in-one machine to be widely used in various electrical equipment and power systems, meeting diverse processing needs. At the same time, it also saves equipment investment costs, maintenance costs, and labor costs for enterprises, and improves production efficiency and economic benefits.

[0045] In summary, the busbar punching, shearing and bending integrated machine of the present invention realizes efficient, high-quality and low-cost production of busbar processing through technical optimization and innovation in many aspects such as high integration, automation, high-precision processing, stability and reliability, flexibility and adaptability. The integrated machine not only improves production efficiency and quality, but also brings significant economic and social benefits to enterprises. It has broad application prospects and market value in the field of electrical industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

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

[0067] The feeding assembly 2 is used to convey the unprocessed busbars. The feeding assembly can efficiently and accurately convey the unprocessed busbars to the subsequent processing links, which improves the production efficiency and processing accuracy. The punching and cutting assembly 3 is used to punch and cut the busbars conveyed by the feeding assembly. The punching and bending assembly is adjacent to the discharge port of the feeding assembly. The assembly integrates the punching and cutting functions, and can complete the punching and cutting of the busbars in one operation, reducing the processing steps and time, and improving the production efficiency. At the same time, the precise punching and cutting ensure the consistency and high quality of the busbar processing. This function enables the all-in-one machine to complete the complete processing process from raw materials to finished products, improving the convenience and efficiency of production. The bending assembly 4 is used to bend the punched busbars according to the designed angle. The bending assembly can bend the punched busbars according to the predetermined angle according to the design requirements, realizing the precise forming of the busbars. This function enables the all-in-one machine to complete the entire processing process 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 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 one device, the all-in-one machine achieves a high degree of integration and automation of busbar processing. This design not only reduces the footprint and complexity of the equipment, but also greatly improves production efficiency and processing accuracy. At the same time, the all-in-one machine also has the advantages of easy operation and convenient maintenance, which can significantly reduce the user's use cost and maintenance burden. Therefore, the all-in-one machine has broad application prospects and market value in the electrical industry.

[0069] For further details, please refer to Figures 6 to 9 The loading assembly 2 includes a loading base plate 21. As the basic structure of the loading assembly, the loading base plate provides a stable support platform to ensure the stability of the busbar during the conveying process. The loading base plate is provided with several rollers 22 along the conveying direction. The design of being installed on the roller frame can effectively support and guide the busbar to be conveyed forward. The rolling of the rollers reduces the friction between the busbar and the base plate, and improves the conveying efficiency. The rollers are installed on the roller frame 23, and the roller frame is installed on the loading base plate. The busbar clamping and conveying devices 24 are provided on both sides of the rollers, which are used to clamp the two non-punching surfaces of the busbar and convey the busbar to the punching and cutting assembly. The busbar clamping and conveying devices arranged on both sides of the rollers can clamp the two non-punching surfaces of the busbar to ensure that the busbar will not deviate from the predetermined trajectory during the conveying process, and stably convey it to the punching and cutting assembly. This design improves the accuracy and reliability of transportation, while preventing the punching surface of the busbar from being damaged, avoiding the sharp-corner discharge caused by the punching process that may cause equipment failure or even safety accidents; a support plate 25 is provided between adjacent rollers, and the rollers are higher than the upper surface of the support plate, which can provide additional support between the rollers to ensure that the busbar will not sag or deform due to gravity during transportation, thereby maintaining the flatness and processing quality of the busbar.

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

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

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

[0073] Further preferably, the clamping drive device 27 adopts a cylinder or an oil cylinder, which connects the main clamping and feeding mechanism and the auxiliary clamping mechanism, and provides a holding force for the main clamping and feeding mechanism and the auxiliary clamping mechanism to clamp the busbar. In the present invention, in addition to the screw nut pair, the clamping drive device can also adopt a cylinder or oil cylinder design, which simplifies the device structure, and directly connects the main clamping and feeding mechanism and the auxiliary clamping mechanism through the cylinder or oil cylinder, thereby achieving a faster and more accurate clamping action. The strong and stable holding force provided by the cylinder or oil cylinder ensures the stability of the busbar during the processing, thereby improving the overall processing efficiency and accuracy.

[0074] Further preferably, the main clamping and feeding mechanism 240 includes a main clamping movable plate 241. The main clamping movable plate serves as the main bearing component of the main clamping and feeding mechanism, and its design ensures stability during clamping and conveying. Through cooperation with the linear guide and the main linear slider, the main clamping movable plate can move smoothly along the predetermined track, providing a basis for the precise conveying of the busbar. Main linear sliders 242 cooperating with the linear guide are installed on both sides below the main clamping movable plate 241. The close cooperation between the main linear slider and the linear guide ensures the linearity and stability of the main clamping movable plate during movement. This design reduces friction and vibration during movement, and improves the accuracy and efficiency of busbar conveying. A main clamping assembly 243 is installed above the main clamping movable plate. The main clamping assembly is the core part of the main clamping and feeding mechanism, and is designed to firmly clamp the busbar. The main clamping group 243 includes N main clamping wheels 2430 provided through the axle along the conveying direction of the busbar below the main clamping movable plate near the roller side, where N is an integer greater than or equal to 2. The provision of multiple main clamping wheels (at least two) increases the contact area and clamping force with the busbar, and improves the stability and reliability of the clamping. At the same time, the design of multiple clamping wheels also helps to disperse the impact force during the busbar conveying process and protect the busbar from damage. Through the synergistic effect of multiple main clamping wheels, the main clamping assembly can evenly distribute the clamping force to ensure that the busbar will not loosen or deviate during the conveying process. The main clamping wheel is connected to a driving component 2431, and the driving component is connected to a feeding servo motor 2432; the driving component transmits the power of the feeding servo motor to the main clamping wheel, thereby realizing 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 wheel when clamping and releasing the busbar.

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

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

[0077] This design brings the following significant technical effects:

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

[0079] Synchronous clamping: Since all main clamping wheels are driven by the same drive member, they can achieve synchronous clamping and release. This ensures that the busbar is evenly stressed during the clamping process, avoiding deviation or deformation caused by inconsistent clamping force.

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

[0081] Energy saving: Using a single drive member and servo motor to drive multiple main clamping wheels is more energy-efficient and efficient than the design in which each clamping wheel is equipped with an independent drive source. This helps to reduce the operating cost of the equipment and meets the requirements of modern industry for energy saving and environmental protection.

[0082] Improved stability: The unified drive components and servo motor control system reduce errors and jitters in mechanical transmission and improve the stability of the entire main clamping and feeding mechanism. This helps ensure accurate positioning and stable conveying of the busbar during processing.

[0083] Further preferably, the driving member is a synchronous toothed belt, which is connected to the output gear of the feeding servo motor; a gear 2433 that cooperates with the synchronous toothed belt is installed on the axle of the main clamping wheel above the main clamping movable plate; a synchronous toothed belt pressure roller 2434 is provided between adjacent gears. The synchronous toothed belt is used as a driving member to connect the output gear of the feeding servo motor and the gear on the main clamping wheel, thereby realizing the precise transmission of power. The close cooperation between the synchronous toothed belt and the gear ensures the synchronization and accuracy of the main clamping wheel when clamping and conveying the busbar. The synchronous toothed belt pressure roller provided between adjacent gears further enhances the stability and reliability of the transmission.

[0084] In addition, the preferred options for the drive components also include chains or gears, which provide more flexibility and adaptability to meet the needs of different application scenarios. Overall, this technical feature improves the performance and stability of the main clamping and feeding mechanism through precise mechanical design and efficient transmission methods, ensuring efficient busbar processing.

[0085] Further preferably, the secondary clamping mechanism 250 includes a secondary clamping movable plate 251, secondary linear sliders 252 cooperating with the linear guide rail are installed on both sides below the secondary clamping movable plate, a secondary clamping movable plate 251 is installed above the secondary clamping movable plate, and N secondary clamping wheels 253 are arranged through the wheel axle below the secondary clamping movable plate near the roller side along the busbar conveying direction, where N is an integer greater than or equal to 2. It is mainly reflected in its precise structural design and efficient clamping function. Through the ingenious cooperation of the secondary clamping movable plate with the linear guide rail and the secondary linear slider, the mechanism realizes stable and linear movement in the busbar conveying direction, providing a strong guarantee for the precise positioning of the busbar. The secondary clamping movable plate installed above the secondary clamping movable plate and the N secondary clamping wheels (N≥2) arranged below 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 the uniform distribution of the clamping force, thereby effectively preventing the busbar from loosening or deflecting during the conveying process. The synergistic effect of multiple auxiliary clamping wheels improves the stability and reliability of clamping, creating favorable conditions for subsequent processing operations. In summary, the auxiliary clamping mechanism provides a solid guarantee for the efficient and stable processing of busbars through its precise structural design and efficient clamping function.

[0086] Further preferably, a spacing maintaining assembly 28 is provided between the main clamping movable plate and the auxiliary clamping movable plate.

[0087] For further details, please refer to Fig.10 The spacing holding assembly 28 includes a holding rod 280, which is located above the roller 22 and has a space for the busbar to pass through between the holding rod and the roller. One end of the holding rod is connected to the main clamping movable plate or the auxiliary clamping movable plate through a shear pin 281, and the corresponding auxiliary clamping movable plate and the main clamping movable plate are provided with a guide hole 282; a positioning block 283 is vertically provided along the radial direction of the guide hole for abutting the holding rod to make the holding rod position relatively static, and the upper part of the positioning block is connected to a positioning cylinder 284 or an oil cylinder that drives the positioning block to move up and down. Its technical effect is remarkable. First, through the ingenious design between the holding rod and the roller, a stable passing space is provided for the busbar, ensuring the smoothness and accuracy of the busbar during the transportation process. Secondly, one end of the holding rod is connected to the main clamping movable plate or the auxiliary clamping movable plate through a shear pin. This connection method not only ensures the firmness of the connection, but also facilitates quick replacement or adjustment when needed. Furthermore, the setting of the guide hole and the positioning block enables the holding rod to remain relatively static in the radial direction, further improving the stability of the busbar transportation. Finally, the introduction of the positioning cylinder or oil cylinder realizes the precise control of the positioning block, so that the position and spacing of the retaining rods can be flexibly adjusted according to needs. In summary, the spacing retaining component provides a more stable and reliable guarantee for busbar processing through its precise design and efficient functions.

[0088] On the basis of the above, the role of the shear pin is particularly important. It not only serves as a connector between the retaining rod and the main clamping moving plate or the auxiliary clamping moving plate, but also can automatically shear at the shear pin when the force is too large, thereby effectively protecting the clamping servo motor from damage. This design cleverly utilizes the mechanical properties of the shear pin. When the external force exceeds the shear pin's bearing limit, the shear pin will break quickly, thereby cutting off the excessive force transmitted to the servo motor and ensuring that the service life of the motor is not affected. 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.

Its technical effect is mainly reflected in the effective restriction of the busbar tilting up. This design provides a stable installation foundation for the entire assembly through the limit mounting plate. The vertical installation of the clamping cylinder and the clamping plate connected to its lower end can flexibly adjust the clamping force on the busbar as needed to ensure that the busbar remains flat during transportation. The busbar clamping wheel at the lower end of the clamping plate further enhances the clamping effect while reducing friction damage with the busbar.

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