[0002] Traditionally, large copper busbars are processed by first drawing them with a drawing machine and then straightening them initially. They are then cut by a cutting device. The cut copper busbars are quite heavy, weighing up to 1 ton, so they cannot be handled manually and require the use of cranes and other auxiliary equipment for transportation. However, during the lifting and transportation process using cranes, the copper busbars are prone to rigid deformation, which affects the processing quality. For copper busbars weighing several hundred kilograms, manual transportation is labor-intensive, time-consuming, and prone to rigid deformation. As a result, the processing of large copper busbars is difficult and the processing quality cannot be guaranteed. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] like Figure 1 As shown, the large-scale automatic copper busbar drawing production line includes a drawing mechanism 100, a station transfer mechanism 200, a lifting and conveying mechanism 400, a side bending and straightening mechanism 500, and a sawing device 600. The station transfer mechanism 200 conveys the copper busbars on the drawing mechanism 100 to the lifting and conveying mechanism 400, the lifting and conveying mechanism 400 conveys the copper busbars to the side bending and straightening mechanism 500, the side bending and straightening mechanism 500 straightens the copper busbars, and the straightened copper busbars enter the sawing device 600 for sawing.

[0042] In this embodiment, as Figures 2-7 As shown, the copper busbar drawing mechanism 100 includes a head 110, a tailstock 130, and a connecting seat 150. The connecting seat 150 is disposed between the tailstock 130 and the head 110. A hydraulic drawing mechanism 140 is mounted on the tailstock 130. In this embodiment, the hydraulic drawing mechanism 140 is prior art, therefore its specific structure and working principle will not be described in detail. Figure 3 , Figure 4 and Figure 5 As shown, the machine head 110 includes a head base 101, on which a feeding groove 102 is provided. The two walls of the feeding groove 102 have slots 106 extending downwards from top to bottom. A template 104 is slidably installed within the slots 106. A feeding mold 105 is installed on the template 104. The feeding mold 105 has a discharge hole 109 through which a copper busbar passes. In use, the feeding mold 105 is installed on the template 104, and then the template 104 is lifted to the machine head 110 using a lifting device. Above 0, the template 104 moves downward and is inserted into the slot 106, thus installing the template 104. Since the template 104 and the slot 106 are in a sliding fit, the template 104 cannot move in the front-to-back direction, ensuring the reliability of the template 104. When it is necessary to replace the feeding mold 105, simply lift the template 104 to remove it from the slot 106, making the feeding mold 105 easy to install and remove. Furthermore, as... Figure 6 and Figure 7 As shown, the template 104 has a tapered hole that is smaller at the front and larger at the back. The outer edge of the feed mold 105 has a tapered surface that matches the tapered hole. Preferably, the tapered surface of the feed mold 105 and the tapered hole are tightly fitted together. Therefore, after the feed mold 105 and the template 104 are installed, the feed mold 105 will not easily separate from the template 104. During use, the copper busbar moves forward, thereby applying a forward thrust to the feed mold 105, which ensures the reliability of the installation between the feed mold 105 and the template 104, and thus ensures the reliability of the copper busbar drawing process.

[0043] In this embodiment, as Figure 3 As shown, a limiting plate 103 is horizontally installed in the feed groove 102 of the head seat 101. A limiting block is provided at the front end of the limiting plate 103. The limiting plate 103 is located below the template 104, and the limiting block is located in front of the template 104. The limiting plate 103 can limit the horizontal height of the template 104, thereby ensuring that the hydraulic pulling mechanism 140 can stably clamp the head of the copper busbar.

[0044] In this embodiment, as Figure 6 As shown, in order to facilitate the lifting of the template 104, a lifting lug 107 is detachably installed on the top of the template 104.

[0045] In this embodiment, as Figure 5 As shown, the headstock 101 of the machine head 110 is also equipped with a sawing mechanism 120 for cutting copper busbars. When the hydraulic pulling mechanism 140 pulls the copper busbar to a specified length, the sawing mechanism 120 starts working, thereby cutting the copper busbar. Further, as... Figure 5 As shown, the sawing mechanism 120 includes a sawing mounting plate 121, the rear end of which is mounted on the headstock 101, as... Figure 4As shown, the rear end of the sawing mounting plate 121 is provided with a template loading / unloading hole 122 for loading / unloading the template 104, as shown. Figure 5 As shown, the front end of the sawing mounting plate 121 is located in front of the headstock 101, and a lead screw locating joint 123 is installed below the sawing mounting plate 121. A moving frame 125 is installed on the lead screw locating joint 123, and a servo motor 126 is installed on the moving frame 125. A saw blade 127 for cutting copper busbars is installed at the power output end of the servo motor 126. When the servo motor 126 works, it causes the saw blade 127 to rotate. When the motor on the lead screw locating joint 123 drives the lead screw to rotate, it drives the moving frame 125 to move, thereby bringing the saw blade 127 closer to the copper busbar and finally cutting the copper busbar. Then the lead screw locating joint 123 returns to its original position. Furthermore, a linear motion device is also installed at the bottom of the sawing mounting plate 121. The bottom of the linear motion pair 124 is mounted on the moving frame 125. The linear motion pair 124 ensures the straightness of the movement of the moving frame 125, thereby ensuring the reliability of the cutting between the saw blade 127 and the copper busbar. In this embodiment, both the linear motion pair 124 and the lead screw motion pair 123 are commercially available products. There are two linear motion pairs 124, and the two linear motion pairs 124 are symmetrical about the lead screw motion pair 123. The linear motion pair 124 includes a linear guide rail and a linear slider 220. The linear guide rail is mounted on the bottom of the sawing mounting plate 121, and the linear slider 220 is mounted on the top of the moving frame 125. The linear slider 220 is slidably mounted on the linear guide rail.

[0046] In this embodiment, as Figure 3 and Figure 5 As shown, a raised plate 108 is provided on the top of the head seat 101, and the rear end of the sawing mounting plate 121 is mounted on the raised plate 108. Through the raised plate 108, there is enough space between the sawing mounting plate 121 and the copper busbar to install the saw blade 127, the lead screw moving pair 123, the linear moving pair 124 and the moving frame 125.

[0047] In this embodiment, as Figure 8 , Figure 9As shown in Figure 10, the workstation transfer mechanism 200 includes several integral conveying mechanisms, which are arranged laterally at intervals. The copper busbar is supported by these integral conveying mechanisms, thus avoiding rigid deformation of the copper busbar. Of course, the copper busbar will still bend when supported by multiple integral conveying mechanisms, but this bending is plastic deformation rather than rigid deformation. When placed on a flat surface, the copper busbar is in a straight state. In this embodiment, the integral conveying mechanism includes a longitudinally conveying chain conveyor. Multiple chain rubber blocks 218 are spaced apart on the conveyor chain 202 of the chain conveyor. Preferably, the chain rubber blocks 218 are evenly distributed on the conveyor chain 202. A translation slide plate 203 is installed at the bottom of one end of the chain conveyor, and the bottom of the other end of the chain conveyor is... The translation slide 203 is equipped with a guide slide 204. Linear guide devices 216 are installed at the bottom of both the translation slide 203 and the guide slide 204. The linear guide devices 216 are mounted on a second support frame 201. A longitudinally distributed rack is also installed at the bottom of the translation slide 203. Sinking platforms 217 are provided on both sides of the second support frame 201 located below the translation slide 203. Bearing seats 205 are installed on the sinking platforms 217. A rotatable rotating shaft is installed between the two bearing seats 205. The rotating shaft is driven by a first drive device. Gears are mounted on the rotating shaft, meshing with the rack. When the first drive device operates, it drives the gears to rotate, thereby causing the translation slide 203 to move. Because the translation slide 203 and the guide slide 204... The bottom of each component is equipped with a linear guide device 216 to ensure the straightness of the movement of the translation slide plate 203. Furthermore, the presence of the linear guide device 216 ensures the reliability of the gear and rack meshing. In this embodiment, when the workstation transfer mechanism 200 is in its initial state, the right end of the chain conveyor is located above the lifting conveyor mechanism 400, while the left end of the chain bolt conveyor is located on one side of the pulling mechanism 100. When the copper busbar is pulled out by the hydraulic pulling mechanism 140, the first drive device operates, causing the left end of the chain conveyor to move above the connecting seat 150. At this time, the copper busbar is located above the left end of the chain conveyor. After the copper busbar is cut, it falls onto the chain conveyor, and then the first drive device rotates in the opposite direction. This causes the chain conveyor to reset, at which point the copper busbar disengages from the drawing mechanism 100. The chain conveyor then rotates again, transporting the copper busbar above the lifting conveyor 400, thus transferring the copper busbar processing station. In this embodiment, the large-scale automatic copper busbar drawing production line also includes a copper busbar straightening mechanism 300, located between the drawing mechanism 100 and the lifting conveyor 400. The station transfer mechanism 200 longitudinally spans the copper busbar straightening mechanism 300. The copper busbar straightening mechanism 300 includes a base, with hydraulic drawing devices at both ends. The hydraulic drawing devices are existing technology and will not be described in detail. Preferably, when the copper busbar falls from the drawing mechanism 100 onto the chain conveyor, the chain conveyor resets.At this point, the copper busbar is in the straightening station. This station primarily straightens any bends in the copper busbar. During the pulling process, the middle of the copper busbar may naturally bend, and it may also bend when it falls onto the chain conveyor. Furthermore, since both ends of the copper busbar are suspended on the chain conveyor, they may also bend. Therefore, two hydraulic pulling devices clamp the ends of the copper busbar and apply tension to straighten it. After holding the pressure for a certain period, the hydraulic pulling devices stop working, and then the chain conveyor resumes its rotation, transporting the copper busbar above the lifting conveyor mechanism 400.

[0048] In this embodiment, as Figure 8 , Figure 9 and Figure 10 As shown, the chain conveying device includes a chain mounting frame 207. One end of the chain mounting frame 207 is mounted on a translation slide plate 203, and the other end is mounted on a guide slide plate 204. A drive sprocket 215 is mounted on one end of the chain mounting frame 207, and a driven sprocket 214 is mounted on the other end. A conveyor chain 202 surrounds the drive sprocket 215 and the driven sprocket 214. The drive sprocket 215 is driven by a second drive device, which is mounted on one side of the chain mounting frame 207 and rotates synchronously with the chain mounting frame 207. In this embodiment, the shaft of the drive sprocket 215 of the chain conveying device is connected to form a second horizontal shaft 209, which is driven by the second drive device. Furthermore, the second driving device includes a second driving motor 210, which drives the second horizontal shaft 209 to rotate via chain transmission. Therefore, when the second driving motor is working, it realizes the synchronous rotation of several chain conveying devices, thereby realizing the synchronous translation of the copper busbar on the chain conveying device. This avoids the copper busbar from being skewed due to the asynchronous rotation of multiple chain conveying devices. In this embodiment, the copper busbar is a large copper busbar with a heavy weight, usually between 1 ton and 1 ton. Therefore, the requirements for the conveyor chain 202 are extremely high. In this embodiment, multiple chain rubber blocks 218 are evenly spaced on the conveyor chain 202. The chain rubber blocks 218 can support the copper busbar and are not easily deformed, thereby ensuring the translational transport of the copper busbar.

[0049] In this embodiment, because the copper busbar is relatively heavy, the tension requirement for the conveyor chain 202 is relatively high. Therefore, if... Figure 8 and Figure 11As shown, a longitudinal notch is provided at one end of the chain mounting bracket 207, and a driven sprocket shaft 213 is installed in the longitudinal notch. A rotatable driven sprocket 214 is installed on the driven sprocket shaft 213. Fixing plates 212 are arranged laterally on both sides of the chain mounting bracket 207. Adjusting screws 211 are threaded on the fixing plates 212. The adjusting screws 211 abut against the corresponding driven sprocket shaft 213. By rotating the adjusting screws 211, the driven sprocket shaft 213 is pushed to move, thereby making the conveyor chain 202 tensioned, which further ensures that the copper busbar is supported and translated by the conveyor chain 202.

[0050] In this embodiment, as Figure 12 As shown, the linear guide device 216 includes longitudinally distributed sliders 220 and slide rails 219. The slide rails 219 are mounted on the corresponding second support frame 201. Sliders 220 are installed on the bottom of both the guide slide plate 204 and the translation slide plate 203. The corresponding sliders 220 are slidably mounted on the slide rails 219. Furthermore, dovetail grooves are provided on the slide rails 219. Since the sliders 220 and slide rails 219 are installed together, vertical derailment of the sliders 220 and slide rails 219 can be avoided. Moreover, the linear guide device 216 can ensure the straightness of the movement of the chain mounting frame 207.

[0051] In this embodiment, as Figure 8 As shown, the rotating shafts of several integral conveying mechanisms are connected to form a first horizontal shaft 206. The first horizontal shaft 206 is driven by a first driving device. Furthermore, the first driving device includes a first driving motor 208. The first driving motor 208 drives the first horizontal shaft 206 to rotate through chain transmission. Therefore, only one first driving motor 208 is needed to realize the synchronous movement of multiple translation slide plates 203, thereby ensuring the synchronous translation movement of the chain mounting frame 207.

[0052] In this embodiment, as Figure 13 , Figure 14 and Figure 15As shown, the lifting and conveying mechanism 400 includes a conveying frame 430, with several idlers 420 mounted horizontally across the top of the conveying frame 430. The idlers 420 are spaced apart. In this embodiment, the idlers 420 are driven by a drive device mounted on the conveying frame 430. Furthermore, some idlers 420 are active idlers, while the remaining idlers 420 are driven idlers. The active idlers are driven by a chain, and the drive device drives one of the active idlers to rotate. The drive device can be a servo motor 126, which then transmits power to the active idler via a chain. When the servo motor 126 is working, it drives the active idler to rotate. The roller 420 is covered with a layer of rubber coating 421. When the copper busbar is placed on the idler roller 420, there is a large friction between the copper busbar and the rubber coating 421. When the idler roller 420 rotates, the copper busbar is conveyed. In this embodiment, since the copper busbar is a large copper busbar, its own weight is relatively heavy, so manual handling is troublesome, especially during the process of changing work stations, the transfer of the copper busbar is difficult. In this embodiment, the copper busbar lifting and conveying device is mainly used for the transportation of copper busbars between the correction work station and the sawing work station. After the copper busbar is corrected, it is moved to the top of the copper busbar lifting and conveying device by the overall conveying device. Therefore, in order to transfer the copper busbar, in this embodiment, as Figure 13 and Figure 14 As shown, the conveyor frame 430 is also equipped with several top support mechanisms 410, which are spaced apart, such as... Figure 16As shown, the top support mechanism 410 includes a mounting frame 411, which is installed inside the conveyor frame 430. A lifting cylinder 412 is installed at the bottom of the top plate of the mounting frame 411. The telescopic rod of the lifting cylinder 412 is located above the top plate, and a load-bearing frame 415 is installed at the top of the telescopic rod. A lifting panel 416 is provided at the top of the load-bearing frame 415, and a rubber block 417 is installed at the top of the lifting panel 416. Several guide rods 413 are also installed at the bottom of the load-bearing frame 415. The guide rods 413 pass through the top plate and slide with the top plate. When the lifting cylinder 412 is in the retracted state, the top surface of the rubber block 417 is at a lower horizontal position than the top surface of the rubber coating 421. When the lifting cylinder 412 is working, the telescopic rod of the lifting cylinder 412 extends... The guide rod 413 prevents the support frame 415 from tilting during its upward movement. As the support frame 415 moves upward, the rubber block 417 moves upward and contacts the bottom surface of the copper busbar. Finally, the copper busbar is lifted by the rubber block 417, at which point the copper busbar is separated from the copper busbar conveying device, the copper busbar conveying device resets, and then the lifting cylinder 412 resets. When the rubber block 417 moves downward, and the top horizontal plane of the rubber block 417 is lower than the top horizontal plane of the rubber coating 421, the copper busbar is supported by several rollers 420. Then, under the rotation of the rollers 420, the copper busbar is transported and enters the next station. Of course, the lifting mechanism 410 will not interfere with the rollers 420 during the lifting and resetting process.

[0053] In this embodiment, as Figure 15 and Figure 16 As shown, the width of the support frame 415 is smaller than the width of the top cavity of the conveyor frame 430, thereby avoiding interference between the support frame 415 and the conveyor frame 430 during the lifting process. The width of the lifting panel 416 is larger than the width of the top cavity of the conveyor frame 430. When the lifting cylinder 412 retracts and the lifting panel 416 descends and contacts the top of the conveyor frame 430, it indicates that the lifting cylinder 412 has moved to the lower stroke, and thus the lifting panel 416 has a limiting function.

[0054] In this embodiment, as Figure 16 As shown, a guide sleeve 414 corresponding to the guide rod 413 is installed on the top plate of the mounting frame 411. The guide rod 413 is slidably fitted in the guide sleeve 414. Furthermore, there are two guide rods 413, and the two guide rods 413 are symmetrical about the telescopic rod. Through the cooperation between the guide sleeve 414 and the guide rod 413, the straightness of the movement of the load-bearing frame 415 is ensured, and the tilting of the load-bearing frame 415 after bearing the load is also avoided.

[0055] In this embodiment, due to the inconsistent models of the copper busbars and the wear and tear on the adhesive block 417 during long-term use, and the need to ensure the copper busbars disengage from the overall conveying mechanism when the telescopic rod moves to the upper stroke, the upper stroke of the adhesive block 417 is relatively heavy. Therefore, in this embodiment, if... Figure 16 As shown, both the guide rod 413 and the telescopic rod are provided with threaded heads at their tops. The threaded heads are connected to the load-bearing frame 415 through a threaded adjustment device. The threaded adjustment device includes a second threaded sleeve 418, which is detachably connected to the load-bearing frame 415 by a thread. The second threaded sleeve 418 has a threaded hole, and a locking nut 419 is fitted on the threaded head. The threaded head is threadedly connected to the corresponding threaded hole of the second threaded sleeve 418 and locked by the locking nut 419. Therefore, during installation or subsequent adjustment, the upper stroke of the load-bearing frame 415 can be adjusted by adjusting the mating length between the threaded strip and the second threaded sleeve 418, thereby adjusting the upper stroke of the rubber block 417. This ensures that the rubber block 417 can lift the copper busbar, allowing it to detach from the overall conveying mechanism. When the rubber block 417 moves to the lower stroke, it can detach from the copper busbar, allowing the copper busbar to be supported by several rollers 420.

[0056] In this embodiment, as Figure 1 As shown, the copper busbar enters the side bending straightening mechanism 500 via the lifting and conveying mechanism 400. Further, as... Figure 17 and Figure 18As shown, the side bending straightening mechanism 500 includes a frame 1 with a working platform. A fixed frame 2 is installed on the right side of the frame 1, and a baffle 6 is installed on the left side of the frame 1. A hydraulic cylinder 3 is installed on the fixed frame 2, and an insulating column 10 is installed at the end of the telescopic shaft of the hydraulic cylinder 3. The end face of the insulating column 10 is parallel to the surface of the baffle 6, and the direction of movement of the insulating column 10 is perpendicular to the baffle 6. Furthermore, in order to ensure the reliability of the installation of the fixed frame 2 and the baffle 6 with the working platform, reinforcing ribs are provided on both the fixed frame 2 and the baffle 6. The working platform is welded together. Several first support frames 4 are installed at intervals on both sides of the telescopic shaft. Insulating pads 5 are installed on the first support frames 4. A driven roller 12 is installed between two adjacent first support frames 4. An insulating sleeve 9 is fitted onto the driven roller 12. The top of the insulating sleeve 9 is higher than the horizontal height of the insulating pad 5. Insulating blocks 13 are installed at both ends of the right side of the baffle 6. When the copper busbar presses against the insulating sleeve 9, the bottom of the copper busbar contacts the corresponding insulating pad 5. In this embodiment, the sawing device 6... 00 is existing technology, featuring an active roller that moves the copper busbar forward. The copper busbar enters the copper busbar side bending and straightening machine via the lifting and conveying mechanism 400, then contacts the active roller. Finally, the active roller drives the copper busbar forward, causing it to detach from the copper busbar side bending and straightening machine. When the copper busbar needs straightening, the lifting and conveying mechanism 400 stops conveying the copper busbar, and the active roller of the sawing device 600 also stops rotating. Then, the hydraulic cylinder 3 operates, causing the insulating column 10 to contact the right side of the copper busbar, thus pushing the copper busbar to the left. Lateral movement eventually brings the left side wall of the copper busbar into contact with the two insulating blocks 13. If the copper busbar has a lateral bend, when the copper busbar just contacts the insulating column 10, the copper busbar and the insulating column 10 are in line-to-surface contact. When the copper busbar contacts the insulating blocks 13, it is also in line-to-surface contact. As the hydraulic cylinder 3 continues to work, the insulating column 10 will push the copper busbar, causing the copper busbar to deform. Finally, the copper busbar and the insulating column 10 and the insulating blocks 13 are in surface contact, and the copper busbar is straightened. In this embodiment, the insulating blocks 13 and the insulating pad 5 are both made of nylon material.

[0057] In this embodiment, the insulating sleeve 9 fitted on the driven roller 12 is made of cotton material. When the insulating sleeve 9 is not subjected to external force, the insulating sleeve 9 is 3-5mm higher than the insulating pad. When the copper busbar enters the insulating sleeve 9, the insulating sleeve 9 is compressed under the gravity of the copper busbar, which causes the sleeve to deform, so that the bottom of the copper busbar contacts the corresponding insulating pad 5.

[0058] In another embodiment, the insulating sleeve 9 is made of nylon, and springs are provided at both ends of the driven roller 12. That is, a support frame 15 is provided on both sides of the driven roller 12. The support frame 15 is installed on the working platform, and a U-shaped groove is opened on the support frame 15. The two ends of the driven roller 12 are rotatably placed in the U-shaped groove, and springs are installed in the U-shaped groove. The two ends of the driven roller 12 are supported by the springs. When the copper busbar enters the insulating sleeve 9, the copper busbar applies pressure to the driven roller 12, and the spring is deformed by the pressure, which causes the driven roller 12 to move downward. Since the spring has an elastic restoring force, the insulating sleeve 9 on the driven roller 12 contacts the bottom of the copper busbar again. When the copper busbar passes the driven roller 12, the driven roller 12 returns to its original position under the action of the elastic restoring force of the spring, so that the horizontal height of the top of the insulating sleeve 9 is higher than the horizontal height of the insulating pad 5.

[0059] During the copper busbar straightening process, the bottom of the copper busbar contacts the corresponding insulating pad 5. In other words, the weight of the copper busbar is supported by the insulating pad 5. Since multiple insulating pads 5 are placed at intervals along the copper busbar's conveying line, the copper busbar does not experience bending stress in the vertical direction during the straightening process. Furthermore, no stress concentration occurs during the copper busbar's transport on the straightening machine, thus avoiding the stress generated on the straightening machine from affecting the straightening of the copper busbar. Therefore, after the side wall of the copper busbar is subjected to external force, the side-bent copper busbar can be straightened. After holding the pressure for a certain period of time, the copper busbar can achieve rigid deformation. Therefore, when the insulating column 10 is removed from the copper busbar, the copper busbar is still transported in the straightened state.

[0060] In this embodiment, as Figure 17 As shown, horizontal slide rails 7 are installed at both the front and rear ends of the right side of the baffle 6. Horizontal sliders 8 are installed on the horizontal slide rails 7, and insulating blocks 13 are installed on the horizontal sliders 8. The insulating blocks 13 can slide. When the left side wall of the copper busbar contacts the two insulating blocks 13, as the copper busbar is straightened, the length of the copper busbar will differ in its conveyor direction. Therefore, during the straightening process of the copper busbar, the insulating baffle 6 will slide on the horizontal slide rails 7 to adapt to the change in the length of the copper busbar.

[0061] In this embodiment, as Figure 17 As shown, the horizontal slider 8 has a dovetail groove, and the horizontal slide rail 7 has a protrusion that matches the dovetail groove, thereby ensuring the stability of the horizontal slider 8 sliding on the horizontal slide rail 7.

[0062] In this embodiment, as Figure 18As shown, a first threaded sleeve 11 is installed at the end of the telescopic shaft, and an insulating post 10 is fitted inside the first threaded sleeve 11, with the end of the insulating post 10 protruding from the first threaded sleeve 11. During installation, the first threaded sleeve 11 is first threadedly connected to the telescopic shaft, and then the insulating post 10 is assembled into the first threaded sleeve 11. During use, the insulating post 10 is subjected to the reaction force of the copper busbar, so the insulating post 10 is a vulnerable part. Preferably, the insulating post 10 is made of nylon. Therefore, when the insulating post 10 is damaged, it needs to be replaced. At this time, the first threaded sleeve 11 and the insulating post 10 are disassembled separately and then reassembled.

[0063] In this embodiment, as Figure 17 and Figure 18 As shown, the baffle 6 has a notch 14 that is directly opposite to the telescopic shaft. The insulating post 10 can be inserted into the notch 14 to prevent the telescopic shaft from contacting the baffle 6 during the telescopic process, thereby damaging the verticality of the baffle 6.

[0064] The working process of this invention is as follows: After the hydraulic drawing structure pulls the copper busbar from the feed die 105 to a specified length, the left end of the station transfer mechanism 200 moves between the copper busbar and the connecting seat 150. The sawing mechanism 120 cuts the copper busbar, and the cut copper busbar falls onto the station transfer mechanism 200. Then, the station transfer structure resets, and the copper busbar is brought into the copper busbar straightening station. Two hydraulic drawing devices clamp the front and rear ends of the copper busbar respectively, and then apply a pulling force to straighten the copper busbar. After a certain period of pressure, the hydraulic pulling device resets, allowing the copper busbar to be supported again by the chain conveyor. The chain conveyor then operates, transporting the copper busbar above the lifting conveyor 400. The lifting conveyor 400's support mechanism 410 then moves upward, lifting the copper busbar and disengaging it from the chain conveyor. The left end of the station transfer mechanism 200 then moves back between the copper busbar and the connecting seat 150. The support mechanism 410 then resets, placing the copper busbar on the roller 420, thus causing the copper busbar to bend laterally. The copper busbar moves to the straightening station. After entering the side bending and straightening station, the operator can control the position of the copper busbar on the side bending and straightening mechanism by starting and stopping the drive roller of the sawing device 600 and the idler roller 420 of the lifting conveyor mechanism 400. This allows for one or more side bending and straightening operations on the copper busbar as needed. During straightening, the hydraulic cylinder 3 operates, causing the insulating column 10 to contact the right side of the copper busbar, thus pushing the copper busbar to the left. Finally, the left side wall of the copper busbar contacts the two insulating columns. When the copper busbar contacts the insulating block 13, if the copper busbar has a side bend, when the copper busbar and the insulating post 10 just come into contact, the copper busbar and the insulating post 10 are in line-to-surface contact. When the copper busbar contacts the insulating block 13, it is also in line-to-surface contact. As the hydraulic cylinder 3 continues to work, the insulating post 10 will push the copper busbar, causing the copper busbar to deform. Finally, the copper busbar will make surface contact with the insulating post 10 and the insulating block 13, and the copper busbar will be straightened. Finally, the copper busbar will enter the sawing device 600 for cutting. The cut copper busbar will then enter the stacking mechanism for stacking.
