Description

Technical Field

[0001] This invention relates to the technical field of integrated copper busbar cutting and drilling device, and particularly to an integrated copper busbar cutting and drilling device for switchgear. Background Technology

[0002] Switchgear copper busbars, also known as copper busbars or copper busbars, are mostly made of copper. Their cross-section is usually rectangular or chamfered (rounded) rectangular. In power systems, switchgear copper busbars bear the heavy responsibility of transmitting current and connecting various electrical equipment. They are key components for ensuring stable power transmission and distribution. In the production process of switchgear copper busbars, the copper busbars need to be cut to the required length, and holes need to be drilled to connect electrical equipment. The existing processing method is as follows: a power mechanism drives a cutter to produce linear motion to cut the copper busbar placed on the worktable. By controlling the stroke and position of the cutter, copper busbars of different lengths can be cut. A punching device is used, in conjunction with the movement of the worktable or the adjustment of the positioning fixture, to fix the copper busbar in the appropriate position, align the punch rod with the punching position, and drive the punch rod to penetrate the copper busbar to complete the punching operation. If different hole diameters are required, different specifications of punch rods must be changed, and the operation process often relies heavily on manual labor.

[0003] A search revealed that CN118951726B discloses an integrated punching and shearing device for copper busbars in distribution boxes. By using a clamping assembly, shearing blade, lifting component, punching head, and co-moving component, the device punches holes in the copper busbars while shearing them, thus improving the processing efficiency of the copper busbars. It also facilitates the collection and recycling of debris generated during punching and shearing.

[0004] However, equipment used for processing and producing copper busbars often separates the copper busbar cutting and drilling devices. The copper busbar must first be transported to the cutting device for length cutting, and then transferred to the drilling device for drilling. Due to many uncontrollable factors during the transportation process, such as positional deviations and inaccurate placement angles during manual handling, the copper busbar is prone to positioning deviations on different devices. Furthermore, existing copper busbar drilling devices lack flexibility in meeting different hole diameter requirements. Usually, different hole diameters can only be achieved by manually changing the punch rod. When multiple holes of different diameters need to be processed on the same copper busbar, frequent drill bit changes not only increase the labor intensity of workers, but also make the operation cumbersome and time-consuming.

[0005] Therefore, it is necessary to provide an integrated device for cutting and punching copper busbars in switchgear to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a technical solution for an integrated device for cutting and punching copper busbars in switchgear, thereby solving the problems mentioned in the background art, such as the separation of copper busbar cutting and punching devices and the inconvenience of replacing punch rods when punching copper busbars.

[0015] Preferably, the cutting edge of the cutter has an inverted "V" shape.

[0016] Preferably, the switching component includes a first fixed plate, a servo motor, a threaded rod, a threaded seat, and a first movable plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention integrates copper busbar cutting and punching functions into the same device, eliminating the need to transport copper busbars between different devices.

The switching component drives the cutting component and the pushing device to move longitudinally to switch processes.

Then, the cutting component completes the cutting, reducing transportation time and labor costs.

[0022] Meanwhile, the calibration mechanism of the positioning component adjusts the vertical plate spacing through servo cylinders, connecting rods and rotating plates to calibrate the position of the copper busbar.

The first and second turntables are driven to rotate intermittently by an intermittent mechanism, allowing for the switching of punches of different diameters to meet the punching requirements of various copper busbar diameters. The switching component, in conjunction with the pushing component, can flexibly adjust the position of the punches in the longitudinal and transverse directions of the copper busbar to achieve punching at different positions. The cutting component uses an inverted "V" shaped blade for smooth cutting, and the cutting length can be adjusted according to requirements. The entire device does not require frequent manual replacement of components, significantly improving the flexibility and adaptability of copper busbar processing. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1-13 The embodiments provided by the present invention are as follows:

[0051] like Figure 1 and Figure 2 As shown, an integrated device for cutting and punching copper busbars in a switch cabinet includes a processing table 1 for integrated cutting and punching of copper busbars. A mounting frame 3 is installed on the processing table 1. A cutting component 5 and a pushing device 6 are slidably installed on the side wall of the mounting frame 3 via a switching component 4.

[0052] Specifically, such as Figure 6 As shown, the pushing device 6 includes a second fixed plate 61, a second hydraulic cylinder 62, a sliding mechanism, a push rod 69, and a push plate 610. The second fixed plate 61 is fixed on the switching component 4. The second hydraulic cylinder 62 is mounted on the second fixed plate 61. The piston rod of the second hydraulic cylinder 62 is fixedly mounted to the top of the sliding mechanism. The bottom of the sliding mechanism is fixedly mounted to the push rod 69. The push plate 610 is fixedly mounted on the bottom surface of the push rod 69.

[0053] The sliding mechanism includes a third fixed plate 63, a fixed rod 64, a first slide table 65, a second slide table 66, a slide rod 67, and a first spring 68. There are two third fixed plates 63, which are respectively fixedly installed on the switching component 4. The two ends of the fixed rod 64 are respectively fixed between the two third fixed plates 63. The first slide table 65 and the second slide table 66 are slidably installed on the fixed rod 64 through internally installed sliding sleeves. The slide rod 67 is slidably installed near the outer side of the first slide table 65 and the second slide table 66. The two ends of the slide rod 67 are limited by the threaded connection of nuts. The first spring 68 is sleeved on the side wall of the slide rod 67 located between the first slide table 65 and the second slide table 66. The piston rod end of the second hydraulic cylinder 62 is engaged with the top of the first slide table 65. The bottom surface of the second slide table 66 is fixedly installed with the push rod 69.

[0054] When drilling is required on the copper busbar, the second hydraulic cylinder 62 is activated, the piston rod extends and engages with the top of the first slide 65, driving it downward. The first slide 65 slides on the fixed rod 64, and the second slide 66 drives the push plate 610 downward through the push rod 69. The push plate 610 pushes the punching assembly 87 on the second turntable 86 to drill the copper busbar. During this process, the first spring 68 between the first slide 65 and the second slide 66 plays a buffering and resetting role. When drilling is completed and the piston rod of the second hydraulic cylinder 62 retracts, the first spring 68 pushes the first slide 65 and the second slide 66 to reset, so that the pushing device 6 returns to the initial position, ready for the next drilling operation. The function of the pushing device 6 is to provide downward driving force for the punching assembly 87, ensuring that the punch 877 can smoothly penetrate the copper busbar and complete the drilling task. Furthermore, the design of the sliding mechanism ensures the smooth transmission of force and the stable operation of the device during the drilling process.

[0055] like Figure 7 As shown, the follow-up switching station 8 includes a moving table 81, an intermittent mechanism 84, a first turntable 85, and a second turntable 86. A cutting groove 82 for cutting copper busbars to the required length is provided on one side of the moving table 81. The cutter 56 moves up and down in the cutting groove 82 under the drive of the first hydraulic cylinder 52 to cut the copper busbars to different lengths of the required size. The first turntable 85 is rotatably mounted on the other side of the moving table 81. A rotating column 88 is fixedly connected to the center of the first turntable 85. The top of the rotating column 88 is fixedly mounted to the second turntable 86 through a mounting plate 89. The bottom of the rotating column 88 is fixedly mounted to the drive end of the intermittent mechanism 84.

[0056] Multiple punching components 87 are slidably mounted on the second turntable 86. The intermittent mechanism 84 drives the first turntable 85 and the second turntable 86 to rotate intermittently on the moving platform 81. Sliding holes are opened around the second turntable 86, and the multiple punching components 87 are slidably connected in the sliding holes.

[0057] Specifically, such as Figure 8 , Figure 10 and Figure 11As shown, the punching assembly 87 includes a first pressure plate 871, a pressure groove 872, a first slide cylinder 873, a second slide cylinder 874, a second pressure plate 875, a second spring 876, and a punch rod 877. The top surface of the first slide cylinder 873 is fixedly connected to the first pressure plate 871. The first pressure plate 871 has a pressure groove 872 for driving the pushing device 6. The second slide cylinder 874 is slidably installed in the first slide cylinder 873. The second pressure plate 875 is fixedly connected to the bottom surface of the second slide cylinder 874. The second slide cylinder 874 is slidably connected in a sliding hole. The second spring 876 is sleeved on the first slide cylinder 873 and the second slide cylinder 874. The top end of the punch rod 877 is fixedly installed on the inner top surface of the first slide cylinder 873, and the punch rod 877 is slidably connected to the inside of the second slide cylinder 874. The diameter of the punch rods 877 in the multiple punching assemblies 87 increases sequentially.

[0058] It is worth noting that, for example Figure 9 As shown, different hole sleeves 851 with different hole diameters are installed on the first turntable 85 according to the diameter of the punch 877, so as to cooperate with the punch 877 to perform drilling processing for the copper busbar.

[0059] When the second hydraulic cylinder 62 of the pushing device 6 is activated, the piston rod drives the first slide 65 to move downward. The first slide 65 pushes the push plate 610 downward, and the push plate 610 acts on the pressure groove 872 on the first pressure plate 871, causing the first pressure plate 871 and the entire punching assembly 87 to move downward. At this time, the second spring 876 sleeved on the first slide cylinder 873 and the second slide cylinder 874 is compressed. The second slide cylinder 874 slides in the first slide cylinder 873 and simultaneously slides downward in the sliding hole of the second turntable 86, causing the second pressure plate 875 fixed on the bottom surface of the second slide cylinder 874 to press against the surface of the copper busbar, playing a positioning and fixing role and preventing the copper busbar from moving during drilling.

[0060] Next, the punch 877, fixed on the inner top surface of the first slide cylinder 873, moves downwards and, driven by the second hydraulic cylinder 62, penetrates the copper busbar to complete the drilling operation. After drilling is completed, the piston rod of the second hydraulic cylinder 62 retracts, and under the elastic force of the second spring 876, the punching assembly 87 returns to its original position, the punch 877 exits from the copper busbar hole, and components such as the first pressure plate 871 and the second pressure plate 875 return to their initial positions.

[0061] When different hole diameters need to be drilled on the copper busbar, the intermittent mechanism 84 drives the first turntable 85 and the second turntable 86 to rotate intermittently on the moving table 81. As the turntable rotates, punches 877 of different diameters are switched to the working position in sequence. Since the diameter of the punches 877 in the multiple punching components 87 increases one by one, in this way, the appropriate diameter punches 877 can be flexibly selected according to the drilling requirements of the copper busbar to achieve precise drilling of different hole diameters and meet the drilling requirements of different hole diameters of the copper busbar. At the same time, the switching component 4 drives the follow-up switching station 8 to move longitudinally to adjust the longitudinal position of the punches 877 on the copper busbar. Combined with the pushing component 2 driving the transverse movement of the copper busbar, the drilling process can be carried out at different positions according to the required drilling position of the copper busbar.

[0062] It is worth noting that, for example Figure 7 As shown, the moving table 81 has a circular groove for the first turntable 85. The first turntable 85 rotates in the circular groove through a ring bearing. At the same time, a waste trough for waste to fall into is opened on the bottom surface of the circular groove located at the drilling station. The moving table 81 below the waste trough is equipped with a waste guide bin 83 to export and collect the waste generated by drilling on the copper busbar.

[0063] like Figure 5 As shown, the switching component 4 includes a first fixed plate 41, a servo motor 42, a threaded rod 43, a threaded seat 44, and a first moving plate 45. The first fixed plates 41 are respectively fixedly installed on both ends of the side wall of the mounting frame 3. The servo motor 42 is installed on one of the first fixed plates 41. The threaded rod 43 is rotatably installed on the first fixed plate 41. The inside of the threaded seat 44 is threadedly connected to the threaded rod 43. The first moving plate 45 is fixedly installed on the threaded seat 44. Linear guide rails 7 are respectively fixedly installed on the side walls of the mounting frame 3 located on both sides of the threaded rod 43.

[0064] After the servo motor 42 starts, it drives the threaded rod 43 to rotate on the first fixed plate 41. Since the threaded seat 44 is threadedly connected to the threaded rod 43, the rotation of the threaded rod 43 causes the threaded seat 44 to generate linear motion, which in turn drives the first moving plate 45 fixed on the threaded seat 44 to move. The first moving plate 45 slides on the side wall of the mounting frame 3 through the linear guide rail 7 to ensure the smoothness of the movement. At the same time, the follow-up switching station 8 is connected to the switching component 4 through the connecting plate 10. The movement of the first moving plate 45 drives the follow-up switching station 8 to move longitudinally. On the one hand, it can adjust the longitudinal position of the punch 877 on the copper busbar, so that the device can be adjusted according to the needs of copper busbar drilling and cutting. On the other hand, it can also switch the position of the cutting component 5 and the pushing device 6 to switch the drilling or cutting process of the copper busbar.

[0065] The processing table 1 has a groove 11, and a follow-up switching station 8 is slidably installed in the groove 11 via a linear guide rail 7. The two sides of the follow-up switching station 8 are fixedly installed to the switching component 4 via connecting plates 10.

[0066] The linear guide 7 includes a track 71 and a rail seat 72. The rail seat 72 is slidably installed on the track 71. The track 71 is installed on both sides of the groove 11 and also on the side wall of the mounting frame 3. The rail seat 72 in the groove 11 is fixedly installed with the follow-up switching station 8. The rail seat 72 on the mounting frame 3 is fixedly installed with both sides of the first moving plate 45.

[0067] like Figure 12 As shown, the cutting component 5 includes a fixed frame 51, a first hydraulic cylinder 52, a sliding plate 53, a limiting plate 54, a mounting base 55, and a cutter 56. The fixed frame 51 is fixedly mounted on the switching assembly. The first hydraulic cylinder 52 is mounted on the fixed frame 51. The piston rod end of the first hydraulic cylinder 52 is fixedly mounted to the sliding plate 53. The limiting plate 54 is mounted on the fixed frame 51. The two sides of the sliding plate 53 are slidably connected in the sliding cavity opened on the inner side of the limiting plate 54. The bottom surface of the sliding plate 53 is fixedly mounted to the mounting base 55. The cutter 56 is mounted on the mounting base 55.

[0068] It is worth noting that the cutting edge of the cutter 56 has an inverted "V" shape. The inverted "V" shaped cutting edge forms a progressive cutting during cutting, and the force-bearing area of ​​the copper busbar extends from both sides of the cutting edge to the top. Compared with the instantaneous full-section shearing of the flat blade, the shearing force is decomposed into multiple directions, reducing the single-point impact load and making the cutting process more stable. When the copper busbar is punched and needs to be cut, the first hydraulic cylinder 52 is activated, the piston rod extends, and pushes the slide plate 53 to slide down along the sliding cavity of the limiting plate 54. The slide plate 53 drives the mounting base 55 and the cutter 56 to descend. The cutter 56 moves up and down in the cutter groove 82, using its inverted "V" shaped cutting edge to cut the copper busbar into different lengths as required.

[0069] like Figure 2 and Figure 4As shown, a pushing component 2 is installed on the side wall of the processing table 1. The pushing component 2 includes a first support plate 21, a slide block 22, a finger cylinder 23, a clamping plate 24, a lead screw transmission mechanism 25, and a second slide groove 26. The first support plate 21 is installed on the side wall of the processing table 1. The second slide groove 26 is opened on the first support plate 21. The lead screw transmission mechanism 25 is installed in the second slide groove 26. The slide block 22 is installed on the lead screw transmission mechanism 25. The finger cylinder 23 is installed on the slide block 22. The pneumatic fingers of the finger cylinder 23 are respectively equipped with clamping plates 24 for clamping copper busbars. In order to cooperate with the pushing component 2 to push the copper busbars and reduce the friction between the copper busbars and the processing table 1, a first slide groove 13 is opened on one side of the processing table 1 located on the pushing component 2. Multiple sliding rollers 12 are rotatably installed in the first slide groove 13, which further reduces the friction when the copper busbars move and makes the copper busbars move more smoothly.

[0070] During operation, the finger cylinder 23 is activated, and the pneumatic finger drives the clamping plate 24 to close, firmly holding the copper busbar to be cut and punched. Subsequently, the lead screw transmission mechanism 25 operates, and the rotation of the lead screw converts the rotational motion into linear motion through the nut, driving the slide block 22 to slide in the second slide groove 26, thereby driving the clamped copper busbar to move laterally under the mounting frame 3, accurately conveying the copper busbar to the subsequent processing station, preparing it for punching and cutting, and realizing the lateral displacement transmission of the copper busbar on the processing table 1.

[0071] Furthermore, such as Figure 3 and Figure 13 As shown, a calibration component 9 is installed on the back of the mounting frame 3. The calibration component 9 includes a support frame 91, a calibration mechanism, a vertical plate 97, and a thickness adaptation mechanism. The calibration mechanism is fixedly installed on the back of the mounting frame 3 via the support frame 91. The moving end of the calibration mechanism is fixedly installed on the vertical plate 97, and the thickness adaptation mechanism is slidably installed on the vertical plate 97.

[0072] The calibration mechanism includes a second support plate 92, a second moving plate 93, a servo cylinder 94, a connecting rod 95, and a rotating plate 96. The second support plate 92 is fixedly mounted on the support frame 91. There are two second moving plates 93, and both second moving plates 93 are slidably mounted on both sides of the bottom surface of the second support plate 92 via linear guide rails 7. The servo cylinder 94 is fixedly mounted on the bottom surface of the second support plate 92. There are two connecting rods 95, one end of each connecting rod 95 is hinged to one side of the second moving plate 93, and the other end is hinged to the end of the rotating plate 96. The rotating plate 96 is rotatably mounted on the second support plate 92, so that when the servo cylinder 94 drives one of the second moving plates 93 to move, the other second moving plate 93 moves synchronously. Under the action of the connecting rod 95 and the rotating plate 96, the two second moving plates 93 can move towards or away from each other, thereby adjusting the distance between the vertical plates 97. Since the support frame 91 is located on the processing station and its position is fixed, the two vertical plates 97 can push the copper busbar on both sides to calibrate the position of the copper busbar on the station.

[0073] The thickness adaptation mechanism includes a positioning plate 98, a guide rod 99, and a third spring 910. Each vertical plate 97 has a through groove, and a guide rod 99 is installed in each through groove. The positioning plate 98 is slidably mounted on the guide rod 99, and the third spring 910 is sleeved on the guide rod 99.

[0074] It is worth noting that the bottom of the alignment plate 98 located between the two vertical plates 97 is set at an angle, so that when the position of copper busbars of different thicknesses is corrected, the angle of the alignment plate 98 slides at the corner between the two sides of the copper busbar and the top surface, and pushes the alignment plate 98 to compress the third spring 910 and slide on the guide rod 99. This can correct the position of copper busbars of different thicknesses on the one hand, and prevent the ends of the copper busbars from jumping or bending when the copper busbars are cut or drilled.

[0075] The overall workflow is as follows: the finger cylinder 23 in the pusher component 2 clamps the copper busbar to be cut and punched, and the screw drive mechanism 25 drives the copper busbar to be cut and punched to move laterally under the mounting frame 3.

[0076] First, the copper busbar is punched. The sliding mechanism is driven to move downward by the second hydraulic cylinder 62 in the pushing device 6, which pushes one of the punching components 87 on the second turntable 86 to punch the copper busbar placed on the moving table 81. Then, according to the required hole diameter of the copper busbar, the first turntable 85 and the second turntable 86 are driven to rotate intermittently by the intermittent mechanism 84, and the punch rods 877 of different diameters are switched to punch the copper busbar with different hole diameters. At the same time, the switching component 4 drives the follow-up switching station 8 to move longitudinally and adjust the longitudinal position of the punch rod 877 on the copper busbar. The pushing component 2 drives the copper busbar to move laterally, so that different positions can be punched according to the required position of the copper busbar.

[0077] The copper busbar is then punched and cut. After punching, the copper busbar is cut into different lengths and required sizes by the first hydraulic cylinder 52 in the cutting component 5 driving the cutter 56 to move up and down in the cutter groove 82.

[0078] In order to calibrate the position of the copper busbar on the moving table 81 to match the cutting or drilling position, the positioning component 9 corrects the position of the copper busbar to ensure the accuracy of copper busbar cutting and drilling and to prevent deviation.

[0079] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
