Description

Technical Field

[0001] This invention relates to the field of power electrical engineering technology, and specifically to a high-efficiency processing device for power electrical busbars. Background Technology

[0002] Power busbars refer to low-impedance conductors that connect multiple electrical circuits. They are made of copper tubes, aluminum tubes, or copper and aluminum busbars and are supported or suspended by post insulators. As the main trunk line of the power system, their core function is to realize the collection and distribution of electrical energy. They are mainly used in substations, distribution cabinets, and data centers, and have a clear voltage level attribute. Bus trunking, as a derivative product, adopts a closed metal structure to realize high-power power distribution. The bus trunking field is developing towards intelligence and modularization, and new insulation materials are used to improve high-temperature stability.

[0003] In existing technologies, power busbars typically require punching during processing to facilitate installation. After punching, the punched areas are usually chamfered to prevent partial discharge caused by burrs during subsequent use. This is especially true in busbar connectors, where burrs or sharp edges can lead to electric field concentration and significantly reduce insulation performance. Therefore, the punching process for power busbars must include two steps: punching and chamfering. However, traditionally, the punching and chamfering processes are usually performed separately, which increases processing time and results in significant time losses during mass production, thus affecting processing efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-efficiency processing device for power electrical busbars, thereby solving the problems mentioned in the background section.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A high-efficiency processing device for power electrical busbars includes a platform and two punching heads disposed above it, wherein the punching heads are used to punch holes in the power electrical busbars; A support plate is disposed inside the platform and is used to support the electrical busbar during punching. The surface of the support plate has two punching holes and two chamfered holes. The upper chamfering assembly includes two limiting members, which are respectively disposed on the outer circular wall surfaces of the two stamping heads. The working height of the limiting members is adjustable. The outer circular wall surface of the limiting members is provided with a rotatable ring. The outer circular wall surface of the ring is circumferentially distributed with a plurality of chamfering bits at equal intervals. The top of the ring is provided with a guide rod. The bottom of the two stamping heads is provided with a first guide sleeve. The first guide sleeve has a guide groove inside, wherein the upper half of the guide groove is a vertical groove and the lower half is a spiral groove. The guide rod slides inside the guide groove, and the punch head can continuously enter the interior of the punch hole after pressing down to punch. When the punch head punches the hole, the guide rod is located in the upper half of the guide groove, and when the punch head enters the interior of the punch hole, it is located in the lower half of the guide groove. The lower chamfering assembly is used to chamfer the bottom punching hole position after the top punching hole of the power busbar has been chamfered.

[0006] By adopting the above technical solution, it is easy to complete the punching and chamfering of the power busbar simultaneously.

[0007] Preferably, the lower chamfering assembly further includes: two second guide sleeves, the interior of which is the same as that of the first guide sleeve, both having guide grooves, and a forming chamfering cutter inside the second guide sleeve. The outer circular wall surface of the forming chamfering cutter is the same as the top of the ring, both having guide rods. The forming chamfering cutter can extend out from the inside of the chamfering hole, and when the forming chamfering cutter enters the inside of the chamfering hole, the guide rod on the outer circular wall surface of the forming chamfering cutter is located in the vertical groove of the guide groove inside the second guide sleeve. When the forming chamfering cutter extends out to the chamfering hole, the guide rod on the outer circular wall surface of the forming chamfering cutter is located in the spiral groove of the guide groove inside the second guide sleeve.

[0008] By adopting the above technical solution, it is convenient to chamfer the bottom holes of the power busbar.

[0009] Preferably, the support plate is provided with a mounting base on its exterior, the mounting base being adjustable inside the platform, the platform having a first frame on its top, and both punch heads being located inside the first frame. When the mounting base is adjusted, the first frame moves along with it. A first adjusting screw is provided on one side of the first frame, and when the first adjusting screw rotates clockwise, the two punch heads move downwards, and when the first adjusting screw rotates counterclockwise, the two punch heads move upwards.

[0010] By adopting the above technical solution, the distance between the stamping head and the power busbar can be actively controlled to prevent the material from being violently squeezed due to the small gap, resulting in large tearing burrs, or the material from being excessively stretched due to the large gap, resulting in long and tangled burrs.

[0011] Preferably, the platform body is equipped with a conveyor inside, and the top surface of the platform body is equipped with two first mounting plates and two second mounting plates, wherein the two first mounting plates form one group and the two second mounting plates form another group.

The interior of the second cover is equipped with several rotatable second pressure rollers, and a rotatable third adjusting screw is provided on one side of the second cover. The third adjusting screw is threadedly connected to the first mounting plates and the second mounting plates respectively. When the third adjusting screw rotates clockwise, the second cover on one side of each group of first mounting plates and each group of second mounting plates moves closer to each other. When the third adjusting screw rotates counterclockwise, the second cover on one side of each group of first mounting plates and each group of second mounting plates moves further away from each other.

[0012] By adopting the above technical solution, it is convenient to feed the power busbar, and at the same time, it is possible to limit its movement during the feeding process.

[0013] Preferably, the top of the platform is provided with a second frame, which corresponds to the position of the conveyor. The second frame is provided with a first cover inside, and the first cover is provided with a plurality of rotatable first pressure rollers. The top of the first cover is provided with a rotatable second adjusting screw, and the middle part of the second adjusting screw is threaded. The second adjusting screw is threadedly connected to the second frame. The top of the first cover is provided with two positioning posts, which penetrate the second frame. The positioning posts are provided with elastic elements on their exteriors. The second adjusting screw is limited inside the second frame by the thread.

[0014] By adopting the above technical solution, it is easy to press down and limit the top of the power busbar to prevent it from warping.

[0015] Preferably, the top of the platform is provided with a mounting base, the interior of the mounting base is provided with a positioning plate, the bottom of the positioning plate is provided with a cutting blade, and the cutting blade can be raised and lowered.

[0016] By adopting the above technical solution, it is convenient to cut the punched and chamfered power busbars.

[0017] Preferably, the surface of the platform is provided with a second positioning hole, and a conveying wheel is provided inside the second positioning hole, and the conveying wheel can be driven to rotate.

[0018] By adopting the above technical solution, it is convenient to provide further transmission force from the middle part of the power busbar during long-distance transmission, thereby improving its transmission stability.

[0019] Preferably, the bottom of the platform is provided with a wheel-type length measuring sensor, and the roller of the wheel-type length measuring sensor passes through the platform and extends to its top.

[0020] By adopting the above technical solution, it is convenient to monitor the feeding length of the power busbar in real time.

[0021] Preferably, the top of the platform is provided with a pressing member, which can be driven to rise and fall. When punching or chamfering the power busbar, the pressing member is driven to fall, and when the power busbar is being transported, the pressing member is driven to rise.

[0022] By adopting the above technical solution, it is convenient to press down and fix the power busbar during punching and chamfering, so as to prevent the punching force from causing it to deviate.

[0023] In summary, the present invention has the following main beneficial effects: 1. This invention utilizes the ring, chamfering insert, guide rod, and spiral structure of the guide groove in the upper chamfering assembly to simultaneously complete the upper chamfering of the busbar punching position. The forming chamfering cutter in the lower chamfering assembly extends from the chamfering hole and rotates with the help of the spiral structure of the guide groove to chamfer the bottom of the punching hole. This combines punching and upper chamfering into a single process, avoiding the time loss caused by traditional separate processing, significantly improving batch production efficiency, eliminating bottom burrs generated by punching, preventing partial discharge phenomena in subsequent use, and improving the busbar processing quality.

[0024] 2. This invention uses the third adjusting screw to bring the second cover closer together, thus laterally limiting the power busbar. At the same time, after the second adjusting screw releases the limitation, the elastic element causes the first pressure roller to automatically press down on the top of the busbar, preventing the busbar from deviating or warping during long-distance transportation. This ensures that the busbar enters the punching and chamfering station stably and accurately, thereby improving the positional accuracy of punching and chamfering and reducing processing defects.

[0025] 3. This invention enables continuous automated operation of multiple processes, including punching, upper chamfering, lower chamfering, and cutting, by having the lower pressing component fix the busbar, the punching and chamfering assembly complete the hole processing, and the cutting blade cuts the processed busbar to a fixed length during a single feeding process. This significantly shortens the processing cycle and improves overall production efficiency and product consistency. Attached Figure Description

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.

[0029] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A high-efficiency processing device for power electrical busbars includes: a platform 100, a PLC controller 110 fixedly installed on one side of the platform 100, a first frame 200 slidably connected to the top surface of the platform 100, and a connecting plate 240 slidably connected inside the first frame 200. refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8A first hydraulic cylinder 210 is fixedly installed on the top surface of the connecting plate 240. The telescopic rod of the first hydraulic cylinder 210 passes through the connecting plate 240. A connecting part 250 is fixedly installed on the bottom surface of the telescopic rod of the first hydraulic cylinder 210. Two punch heads 251 are fixedly installed on the bottom surface of the connecting part 250. The bottom diameter of the punch head 251 is larger than the top and middle parts of the punch head 251. A limiting part 253 is fixedly provided on the outer circular wall of the punch head 251. The limiting part 253 is connected and fixed to the punch head 251 by bolts. A ring 252 is rotatably connected inside the limiting part 253. Several chamfering blades 254 are evenly distributed on the outer circular wall of the ring 252. The chamfering blades 254 are connected and fixed to the ring 252 by bolts. refer to Figure 4 , Figure 5 and Figure 6 A fixed base 260 is fixedly installed on the bottom surface of the connecting plate 240. Two first guide sleeves 261 are fixedly installed on the bottom surface of the fixed base 260. The position of the first guide sleeves 261 corresponds to the punch head 251. The punch head 251 is movably sleeved with the inner circular wall of the first guide sleeve 261. An installation hole 140 is opened on the top surface of the platform 100. An installation base 340 is slidably connected inside the installation hole 140. Two connectors 220 are fixedly installed on the bottom surface of the installation base 340. One side of the inside of the connector 220 is fixedly installed with the first frame 200. refer to Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 A support plate 300 is fixedly installed inside the mounting base 340. The top surface of the support plate 300 has two punching holes 310 and two chamfering holes 320. A mounting bracket 360 is fixedly installed on the bottom surface of the mounting base 340. A second cylinder 350 is fixedly installed on the bottom surface of the mounting bracket 360. The telescopic rod of the second cylinder 350 passes through and extends into the interior of the mounting bracket 360. A push plate 351 is fixedly installed on the top surface of the telescopic rod of the second cylinder 350. Two shaped chamfers are rotatably connected to the top surface of the push plate 351. The forming chamfering cutter 352 and the mounting bracket 360 have two second guide sleeves 361 fixedly installed inside. The forming chamfering cutter 352 is movably sleeved with the inner circular wall of the second guide sleeve 361. The inner circular wall of the second guide sleeve 361 and the first guide sleeve 261 are both provided with guide grooves 2611. The upper half of the guide groove 2611 is a vertical groove and the lower half is a spiral groove. The outer circular wall of the forming chamfering cutter 352 and the top surface of the ring 252 are both fixedly installed with guide rods 255. The guide rods 255 are movably sleeved with the guide grooves 2611. When the power busbar is delivered to the punching hole 310, the extension rod of the first hydraulic cylinder 210 extends, causing the docking piece 250 to drive the two punching heads 251 to move downwards and press down on the surface of the power busbar to punch it. During this process, the guide rod 255 at the top of the ring 252 slides in the vertical groove of the guide groove 2611 inside the first guide sleeve 261, causing the bottom of the punching head 251 to extend downwards and enter the interior of the punching hole 310. Then, as the punching head 251 continues to move... This causes the limiting member 253 and the ring member 252 to move out of the inside of the first guide sleeve 261. At this time, when the punching head 251 enters the punching hole 310, the guide rod 255 at the top of the ring member 252 will be in the spiral groove of the guide groove 2611 inside the first guide sleeve 261. As the guide rod 255 slides in the spiral groove of the guide groove 2611, the ring member 252 will drive multiple chamfering cutter pieces 254 to rotate and move downward. Then, the multiple chamfering cutter pieces 254 will contact the punching position of the power busbar and complete the chamfering operation. After the above steps are completed, the resetting of the first hydraulic cylinder 210 telescopic rod drives the two punch heads 251 to reset, and then the ring 252 and the limiting member 253 will re-enter the interior of the first guide sleeve 261. At the same time, the guide rod 255 will drive the chamfering cutter 254 to reverse and rise, and finally enter the vertical groove of the guide groove 2611. At this time, the power busbar is continuously supplied to align its punching position with the chamfering hole 320. Then, the telescopic rod of the second cylinder 350 rises, causing the two forming chamfering cutters to... 352 extends from the inside of the second guide sleeve 361 and the chamfering hole 320, and then its cutting edge contacts the power busbar. During this process, the guide rod 255 outside the forming chamfering cutter 352 enters the spiral groove from the vertical groove part of the guide groove 2611 inside the second guide sleeve 361, thereby causing the forming chamfering cutter 352 to rotate and complete the chamfering of the bottom of the punching position of the power busbar. In this way, the hole chamfering can be completed simultaneously during the punching process of the power busbar, improving its mass production efficiency.

[0030] Based on the above embodiments, refer to Figure 6 , Figure 9 , Figure 13 and Figure 15 A first adjusting screw 230 is rotatably connected to one side of the first frame 200. The first adjusting screw 230 is threadedly connected to the connecting plate 240. A lead screw 330 is rotatably connected to the bottom surface of the platform 100. A handwheel 332 is rotatably connected to the bottom surface of the platform 100. A helical gear 333 is fixedly installed at one end of the shaft of the handwheel 332. A gear plate 331 is fixedly installed at one end of the lead screw 330. The gear plate 331 meshes with the helical gear 333. An assembly piece 341 is fixedly installed on the bottom surface of the mounting base 340. The assembly piece 341 is threadedly connected to the lead screw 330. The first adjusting screw 230 is rotated to drive the first hydraulic cylinder 210 and the punch head 251 to adjust their height by rotating the connecting plate 240. This allows for active control of the distance between the punch head 251 and the power busbar, preventing the material from being squeezed too tightly and producing large tearing burrs, or from being stretched too much and forming long and tangled burrs. The handwheel 332 drives the helical gear 333 to rotate the gear plate 331, which in turn rotates the lead screw 330. Under the action of the threaded transmission, the assembly 341 drives the mounting base 340, the first frame 200 and the punch head 251 to adjust their positions, thus adapting them to power busbars with different punching lengths.

[0031] Based on the above embodiments, refer to Figure 2 , Figure 3 , Figure 13 and Figure 14 The top surface of the platform 100 is provided with a first positioning hole 120 and a second positioning hole 130. A conveyor 800 is fixedly installed inside the first positioning hole 120. A first transition plate 121 is fixedly installed on both sides of the inside of the first positioning hole 120. A second transition plate 131 is fixedly installed on both sides of the inside of the second positioning hole 130. A conveyor wheel 132 is rotatably connected inside the second positioning hole 130.

A drive motor is fixedly installed on one side of the inside of the positioning seat 133. 134. A drive pulley 135 is fixedly sleeved on the outer circular wall of the drive shaft of the drive motor 134. A transmission belt 137 is provided between the drive pulley 135 and the driven pulley 136. The drive pulley 135 and the driven pulley 136 are connected by transmission belt 137. A wheel-type length measuring sensor 150 is fixedly installed on the bottom surface of the platform 100. The model of the wheel-type length measuring sensor 150 is Tenglong-LK-90. The roller of the wheel-type length measuring sensor 150 passes through the platform 100 and extends to its top. The wheel-type length measuring sensor 150 and the drive motor 134 are both electrically connected to the PLC controller 110.

[0032] The power busbar can be transported by the conveyor 800. During the transport process, the drive motor 134 drives the conveyor wheel 132 to rotate, so that the power busbar located in the middle part of the platform 100 is further transported. This prevents the power busbar from shifting due to insufficient transport force during long-distance transport. At the same time, during the transport of the power busbar, the roller part of the wheel length measuring sensor 150 will contact it and rotate with the transport to measure its length in real time, thereby ensuring the transport length of the power busbar.

[0033] Based on the above embodiments, refer to Figure 3 and Figure 11 Two first mounting plates 500 and two second mounting plates 510 are fixedly installed on the top surface of the platform 100. The two first mounting plates 500 form a group, and the two second mounting plates 510 form a group. A second cover 520 is provided on one side of each of the first mounting plates 500 and the second mounting plates 510. Several second pressure rollers 522 are rotatably connected inside the second cover 520. A third adjusting screw 521 is rotatably connected to one side of the second cover 520. The third adjusting screw 521 is threadedly connected to the first mounting plate 500 and the second mounting plate 510 respectively. refer to Figure 3 and Figure 10 A second frame 400 is fixedly installed on the top surface of the platform 100. The second frame 400 has a first cover 410 inside. Several first pressure rollers 414 are rotatably connected inside the first cover 410. A second adjusting screw 411 is rotatably connected to the top surface of the first cover 410. The middle part of the second adjusting screw 411 is threaded. The second adjusting screw 411 is threaded to the second frame 400. Two positioning posts 412 are fixedly installed on the top surface of the first cover 410. The positioning posts 412 penetrate the second frame 400. An elastic element 413 is movably sleeved on the outer circular wall of the positioning posts 412. refer to Figure 3 and Figure 12 A mounting base 600 is fixedly installed on the top surface of the platform 100. A second hydraulic cylinder 610 is fixedly installed on the top surface of the mounting base 600. A positioning plate 611 is provided inside the mounting base 600. The top surface of the positioning plate 611 is fixedly installed with the bottom surface of the telescopic rod of the second hydraulic cylinder 610. A cutting blade 620 is fixedly installed on the bottom surface of the positioning plate 611. A pressing member 700 is provided on the top of the platform 100. Two first cylinders 710 are fixedly installed on the bottom surface of the platform 100. The telescopic rod of the first cylinder 710 passes through the platform 100 and is fixedly installed with the bottom surface of the pressing member 700. The third adjusting screw 521, when rotated, allows the second cover 520 on one side of each first mounting plate 500 and each second mounting plate 510 to move closer together under the action of threaded transmission. This limits the position of the power busbar and prevents it from shifting during transport. Then, the threaded part of the second adjusting screw 411 rotates out of the threaded connection between the second frame 400 and the screw, releasing the limit of the first cover 410. Under the action of the elastic force of the elastic element 413, the multiple first pressure rollers 414 inside the first cover 410 press down on the top of the power busbar, preventing it from warping during transport. The lifting and lowering of the pressing element 700 can be controlled by the two first cylinders 710, which presses down and fixes the power busbar during punching and chamfering to prevent it from shifting due to the punching force. Then, the cutting blade 620 is driven to rise and fall by the second hydraulic cylinder 610, which cuts the power busbar after punching and chamfering.

[0034] Working principle: Please refer to Figures 1-15 As shown, by rotating the first adjusting screw 230, the connecting plate 240 drives the first hydraulic cylinder 210 and the punch head 251 to adjust their height. This allows for active control of the distance between the punch head 251 and the power busbar, preventing the material from being squeezed too tightly due to insufficient clearance, resulting in large tearing burrs, or from being stretched too much due to excessive clearance, resulting in long and tangled burrs. The handwheel 332 allows the helical gear 333 to drive the gear plate 331 to rotate, which in turn causes the lead screw 330 to rotate. Under the action of the threaded transmission, the assembly 341 drives the mounting base 340, the first frame 200, and the punch head 251 to adjust their positions, thereby adapting them to power busbars with different punching lengths. After the above steps are completed, by rotating the third adjusting screw 521, the second cover 520 on one side of each group of first mounting plates 500 and each group of second mounting plates 510 can be brought closer to each other under the action of threaded transmission, thereby limiting the position of the power busbar and preventing it from deviating during transportation. Then, by rotating the threaded part of the second adjusting screw 411 out of the threaded connection between the second frame 400 and the screw, the limiting of the first cover 410 is released. Then, under the action of the elastic force of the elastic element 413, the multiple first pressure rollers 414 inside the first cover 410 press down on the top of the power busbar, thereby preventing it from warping during transportation. At this time, the power busbar can be transported by the conveyor 800. During the transport process, the drive motor 134 drives the conveyor wheel 132 to rotate, so that the power busbar located in the middle part of the platform 100 is further transported, thereby preventing the power busbar from shifting due to insufficient transport force during long-distance transport. At the same time, during the transport of the power busbar, the roller part of the wheel length measuring sensor 150 will contact it and rotate with the transport to measure its length in real time, thereby ensuring the transport length of the power busbar. When the power busbar is delivered to the position of the punching hole 310, the extension rod of the first hydraulic cylinder 210 extends, causing the docking part 250 to drive the two punching heads 251 to move downward and press down on the surface of the power busbar to punch it. During this process, the guide rod 255 at the top of the ring 252 slides in the vertical groove of the guide groove 2611 inside the first guide sleeve 261, and then the bottom of the punching head 251 continues to extend downward and enter the interior of the punching hole 310. Then, as the punching head 251 continues to move, it causes... The limiting member 253 and the ring member 252 move out from the inside of the first guide sleeve 261. At this time, when the punching head 251 enters the punching hole 310, the guide rod 255 at the top of the ring member 252 will be in the spiral groove of the guide groove 2611 inside the first guide sleeve 261. As the guide rod 255 slides in the spiral groove of the guide groove 2611, the ring member 252 will drive multiple chamfering cutter pieces 254 to rotate and move downward. Then, the multiple chamfering cutter pieces 254 will contact the punching position of the power busbar and complete the chamfering operation. After the above steps are completed, the resetting of the first hydraulic cylinder 210 telescopic rod drives the two punch heads 251 to reset, and then the ring 252 and the limiting member 253 will re-enter the interior of the first guide sleeve 261. At the same time, the guide rod 255 will drive the chamfering cutter 254 to reverse and rise, and finally enter the vertical groove of the guide groove 2611. At this time, the power busbar is continuously supplied to align its punching position with the chamfering hole 320. Then, the telescopic rod of the second cylinder 350 rises, causing the two forming chamfering cutters to... 352 extends from the inside of the second guide sleeve 361 and the chamfering hole 320, and then its cutting edge contacts the power busbar. During this process, the guide rod 255 outside the forming chamfering cutter 352 will enter the spiral groove from the vertical groove part of the guide groove 2611 inside the second guide sleeve 361, thereby causing the forming chamfering cutter 352 to rotate and complete the chamfering of the bottom of the punching position of the power busbar. In this way, the hole chamfering can be completed simultaneously during the punching process of the power busbar, improving its mass production efficiency. During this process, the lifting and lowering of the pressing component 700 can be controlled by two first cylinders 710, thereby pressing and fixing the power busbar during punching and chamfering to prevent it from shifting position due to the punching force. Then, the cutting blade 620 is driven to lift and lower by the second hydraulic cylinder 610, so that the cutting blade 620 can cut the power busbar after punching and chamfering. In this way, punching, chamfering and cutting of the power busbar can be completed simultaneously in one feeding process, thereby improving the efficiency of mass production of power busbars.
