Description

Technical Field

[0001] This invention relates to the field of copper busbar processing technology, and more specifically, to an automated feeding and extrusion continuous production apparatus for copper busbars. Background Technology

[0002] Copper busbars, also known as copper busbars or copper busbars, are long conductors made of copper with a rectangular or chamfered (rounded) rectangular cross-section (rounded corner copper busbars are now generally used to prevent point discharge). They serve to transmit current and connect electrical equipment in circuits. Copper busbars are widely used in electrical equipment, especially in complete power distribution systems.

[0003] In the mass production of copper busbars, to prevent stress concentration at the corners of rectangular rods that could cause jamming, cylindrical copper rods are typically used as raw materials. However, when the cylindrical copper rod is initially fed between the extrusion and compaction rollers by the conveying mechanism, it is tangential to both rollers. At this point, the rollers do not effectively flatten the rod, and the end of the rod easily gets stuck between them. Furthermore, the insufficient pressure exerted by the rollers on the upper and lower sides of the rod causes relative sliding between the rod and the rollers. The friction generated by the rollers is often insufficient to drive the rod smoothly into the gap, thus affecting the efficiency and stability of continuous copper busbar production.

[0004] In view of this, we propose an automated feeding and extrusion continuous production device for copper busbars to improve the shortcomings of the prior art. Summary of the Invention

[0005] This invention provides an automated feeding and extrusion continuous production device for copper busbars, which solves the problem that when a cylindrical copper rod is initially fed between the extrusion wheel and the compaction wheel, the copper rod end is prone to jamming due to insufficient positive pressure from both wheels.

[0006] To achieve the above objectives, the automated feeding and extrusion continuous production device for copper busbars includes a working module located on the top of the workbench. The working module includes a pair of spaced-apart first mounting plates, with an extrusion assembly rotatably connected between the two first mounting plates. Above the extrusion assembly is an adjustment assembly for changing the thickness of the produced copper busbar. The extrusion assembly includes a pair of symmetrically arranged second drive rollers. A limiting wall is fixedly connected to the second drive roller on the side closer to the other second drive roller. An extrusion wheel is fixedly connected to the limiting wall on the side away from the second drive roller connected to it. The radius of the extrusion wheel is smaller than the radius of the limiting wall. The tops of the two extrusion wheels and the side walls of the two limiting walls form an extrusion groove. The extrusion wheel has several telescopic blocks arranged radially. Each telescopic block is slidably connected to a telescopic block. When the copper rod does not enter the extrusion groove, the telescopic block extends out from the shrinkage groove. When the copper rod enters the extrusion groove and is located directly below the adjustment component, the telescopic block located directly below the adjustment component retracts into the shrinkage groove. The telescopic block that rotates with the limiting wall is used to drive the stuck copper rod into the extrusion groove. The limiting wall has an installation groove on the side near the extrusion groove. A scraper is slidably connected in the installation groove. When the telescopic block extends out of the contraction groove, the scraper retracts into the installation groove. When the telescopic block retracts into the contraction groove, the scraper extends out of the installation groove to scrape off copper shavings at the corners of the extrusion groove.

[0007] In the above technical solution, when the external conveying mechanism conveys the copper rod to be extruded to the vicinity of the extrusion groove, if the upper and lower sides of the end of the copper rod are tangent to the bottom of the adjusting component and the top of the extrusion wheel respectively, the existing extrusion structure is prone to slipping with the copper rod. In this application, the telescopic block upstream of the position of the end of the copper rod first contacts the bottom of the copper rod through its end away from the axis. The copper rod, which is fixed by the upper and lower conveying mechanism, presses the telescopic block back into the shrinkage groove. At this time, the scraping part blocked by the telescopic block loses its blocking function and extends out from the mounting groove, thereby scraping off the stubborn copper shavings accumulated at the corner of the extrusion groove.

[0008] Based on this, a pair of second mounting plates are fixedly disposed above the top of the first mounting plate. The adjustment assembly includes a first drive roller, which is rotatably connected to the two second mounting plates in the horizontal direction and slidably connected to the two second mounting plates in the vertical direction. A biting arm for extending into the extrusion groove is fixedly connected to the outer wall of the first drive roller.

[0009] Based on the above, each of the two ends of the first drive roller that are far apart is rotatably connected to an adjusting arm. The two adjusting arms are slidably connected to the two second mounting plates respectively. A hydraulic rod is provided above each of the two adjusting arms. The hydraulic rod includes a cylinder and a piston rod. The cylinder of the hydraulic rod is fixedly connected to the second mounting plate, and the piston rod of the hydraulic rod is fixedly connected to the adjusting arm.

[0010] With this design, the adjusting arm slides up and down by changing the length of the hydraulic piston rod extension, thereby changing the depth of the biting arm pressing into the extrusion groove. The distance between the bottom of the biting arm and the top of the extrusion groove is the thickness of the copper busbar.

[0011] In another technical solution, when the telescopic block is fully extended from the shrinkage groove, the distance from the telescopic block to the axis is greater than or equal to the distance from the centrifugal side of the mounting groove to the axis, in order to prevent the scraping straight block from extending out of the mounting groove; When the telescopic block retracts into the shrinkage groove, the distance from the telescopic block to the axis is less than or equal to the distance from the centripetal side of the mounting groove to the axis, so that the scraping straight block extends out from the mounting groove to scrape off the copper shavings adhering to the corners of the extrusion groove.

[0012] Furthermore, the shrinkage groove is provided with a snapping spring, which is used to drive the telescopic block that retracts into the shrinkage groove to reset. One end of the snapping spring is fixedly connected to the end of the shrinkage groove away from the groove opening, and the other end of the snapping spring is fixedly connected to the centripetal end of the telescopic block.

[0013] In this technical solution, the copper rod moves axially and is bitten into the compression groove by the friction between the top of the telescopic block and the bottom of the biting arm. After the telescopic block moves away from directly below the limiting wall, the telescopic block, which has retracted into the contraction groove, loses the pressing effect of the copper rod and extends out of the contraction groove to reset under the restoring force of the biting spring.

[0014] In addition, the scraping component includes a trigger arc block and a scraping straight block. The trigger arc block and the scraping straight block are fixedly connected to an anti-detachment baffle on the side away from the extrusion groove. The anti-detachment baffle is used to prevent the scraping straight block from slipping out of the mounting groove.

[0015] Furthermore, a cleaning spring is provided inside the mounting groove. One end of the cleaning spring is fixedly connected to the side of the anti-detachment baffle away from the squeezing groove, and the other end of the cleaning spring is fixedly connected to the side of the mounting groove away from the groove opening.

[0016] Furthermore, the orthographic projection of the trigger arc block on the mounting groove is located on the centrifugal side of the shrinkage groove, and the orthographic projection of the scraping straight block on the mounting groove is located between two adjacent shrinkage grooves. That is, when the telescopic block extends out of the shrinkage groove, the telescopic block can block the trigger arc block located in the mounting groove to prevent the scraping straight block from extending out of the mounting groove.

[0017] Preferably, the radial side of the scraping block slides against the periphery of the extrusion wheel so that the scraping block scrapes away copper shavings from the edges of the extrusion groove when it extends out of the mounting groove.

[0018] The trigger arc block is arc-shaped on the side near the center of the extrusion wheel shaft. When the telescopic block extends out of the contraction groove, the centrifugal side of the telescopic block slides and fits against the centripetal side of the trigger arc block.

[0019] As described above, when the telescopic block is compressed back into the retraction groove by the copper rod, the trigger arc block loses its shielding effect. The scraping straight block is then pushed out of the mounting groove by the previously compressed cleaning spring. The centripetal side of the scraping straight block slides along the centrifugal side of the extrusion wheel, thereby scraping away the stubborn copper shavings adhering to the edges of the extrusion groove. After the telescopic block rotates away from directly under the biting arm, because the deformation restoring force of the biting spring is greater than the deformation resistance of the cleaning spring, the extended telescopic block slides along the centripetal side of the scraping straight block towards the centrifugal side of the telescopic block, thereby pushing the trigger arc block back into the mounting groove. This causes the scraping straight block to retract into the mounting groove simultaneously and compress the cleaning spring.

[0020] Based on the above description, the beneficial effects of the present invention compared with the prior art are as follows: 1. Solves the initial bite problem of copper rods and improves the reliability of automated feeding. By setting a radially retractable telescopic block on the extrusion roller, in conjunction with the reset action of the biting spring, when the copper rod is tangential to the extrusion roller and biting arm, the contact pressure and synchronous rotation of the telescopic block with the copper rod generate sufficient friction to drive the copper rod to move axially and bite into the extrusion groove. This effectively avoids the phenomenon of copper rod end jamming and slippage, and eliminates the need for additional push mechanism or pinch rollers, realizing automatic bite of copper rods and greatly improving the automation level and production continuity of the equipment.

[0021] 2. The device enables automatic cleaning of copper shavings from the corners of the extrusion groove, ensuring production stability and product quality. Through the coordinated operation of the scraper and the telescopic block, the extension and retraction of the scraper block is controlled by the telescopic block's movement. This precisely removes stubborn copper shavings that easily accumulate at the corners of the extrusion groove, preventing problems such as extrusion jamming and scratches on the copper busbar surface caused by shavings buildup. Simultaneously, an anti-slip baffle prevents the scraper from slipping, and a cleaning spring ensures stable and reliable scraping action, reducing the frequency of manual cleaning, lowering labor intensity, and preventing copper shavings buildup from affecting production efficiency and copper busbar product precision.

[0024] The technical solutions in 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.

[0025] When the cylindrical copper rod is initially fed between the extrusion roller and the compaction roller by the conveying mechanism, the copper rod will be tangent to the extrusion roller and the compaction roller respectively. At this time, the extrusion roller and the compaction roller do not effectively flatten the copper rod, and the end of the copper rod is easy to get stuck between the two rollers. At this time, the extrusion roller and the compaction roller will not exert enough positive pressure on the upper and lower sides of the copper rod, which will cause relative sliding between the copper rod and the two rollers. That is, the friction force generated by the extrusion roller and the compaction roller on the copper rod is often not enough to drive the copper rod smoothly into the gap between them, thus affecting the efficiency and stability of continuous copper busbar production.

[0026] Please see Figures 1-3To solve the above problems, the present invention aims to provide an automated feeding and extrusion continuous production device for copper busbars. The production device includes a working module set on the top of the workbench 100. The working module includes a pair of spaced first mounting plates 101. An extrusion assembly 300 is rotatably connected between the two first mounting plates 101. An adjustment assembly 200 for changing the thickness of the produced copper busbar is provided above the extrusion assembly 300. The extrusion assembly 300 includes a pair of symmetrically arranged second drive rollers 301. A limiting wall 311 is fixedly connected to the side of the second drive roller 301 near the other second drive roller 301. An extrusion wheel 310 is fixedly connected to the side of the limiting wall 311 away from the second drive roller 301 connected to it. The radius of the extrusion wheel 310 is smaller than the radius of the limiting wall 311. The tops of the two extrusion wheels 310 and the side walls of the two limiting walls 311 form an extrusion groove. The extrusion roller 310 has a plurality of telescopic blocks 320 arranged radially. Each telescopic block 320 is slidably connected to a telescopic block 320. When the copper rod does not enter the extrusion groove, the telescopic block 320 extends out from the shrinkage groove 321. When the copper rod enters the extrusion groove and is located directly below the adjustment component 200, the telescopic block 320 located directly below the adjustment component 200 retracts into the shrinkage groove 321. The telescopic block 320 that rotates with the limiting wall 311 is used to drive the stuck copper rod into the extrusion groove. The limiting wall 311 has an installation groove 331 on the side near the extrusion groove. A scraper 330 is slidably connected in the installation groove 331. When the telescopic block 320 extends out of the shrinkage groove 321, the scraper 330 retracts into the installation groove 331. When the telescopic block 320 retracts into the shrinkage groove 321, the scraper 330 extends out of the installation groove 331 to scrape off copper shavings at the corners of the extrusion groove.

[0027] In practice, when the external conveying mechanism transports the copper rod to be extruded to the vicinity of the extrusion groove, if the upper and lower sides of the end of the copper rod are tangent to the bottom of the adjusting component 200 and the top of the extrusion wheel 310 respectively, the existing extrusion structure is prone to slipping with the copper rod. In this application, the telescopic block 320 upstream of the position of the end of the copper rod first contacts the bottom of the copper rod through its end away from the axis. The copper rod, which is fixed by the upper and lower conveying mechanism, presses the telescopic block 320 back into the shrinkage groove 321. At this time, the scraper 330 blocked by the telescopic block 320 loses its blocking function and extends out from the mounting groove 331, thereby scraping off the stubborn copper shavings accumulated at the corner of the extrusion groove.

[0028] Next, please refer to Figure 4 and Figure 5To explain the principle of how the adjusting component 200 changes the thickness of the manufactured copper busbar, a pair of second mounting plates 102 are fixedly disposed above the top of the first mounting plate 101. The adjusting component 200 includes a first drive roller 210, which is rotatably connected to the two second mounting plates 102 in the horizontal direction and slidably connected to the two second mounting plates 102 in the vertical direction. A biting arm 211 for extending into the extrusion groove is fixedly connected to the outer wall of the first drive roller 210.

[0029] Based on the above, the two ends of the first drive roller 210 that are far apart are rotatably connected to adjusting arms 201. The two adjusting arms 201 are slidably connected to the two second mounting plates 102 respectively. A hydraulic rod 202 is provided above the two adjusting arms 201. The hydraulic rod 202 includes a cylinder and a piston rod. The cylinder of the hydraulic rod 202 is fixedly connected to the second mounting plate 102, and the piston rod of the hydraulic rod 202 is fixedly connected to the adjusting arm 201.

[0030] In other words, before processing the copper busbar, the adjusting arm 201 is driven to slide up and down by changing the length of the piston rod extension of the hydraulic rod 202 to change the depth of the biting arm 211 pressed into the extrusion groove, and the distance between the bottom of the biting arm 211 and the top of the extrusion groove is the thickness of the copper busbar.

[0031] like Figure 6 and Figure 7 As shown, when the telescopic block 320 is fully extended from the shrinkage groove 321, the distance from the telescopic block 320 to the shaft center is greater than or equal to the distance from the centrifugal side of the mounting groove 331 to the shaft center, which is used to prevent the scraping straight block 332 from extending out of the mounting groove 331. When the telescopic block 320 retracts into the shrinkage groove 321, the distance from the telescopic block 320 to the axis is less than or equal to the distance from the radial side of the mounting groove 331 to the axis, so that the scraping straight block 332 extends out from the mounting groove 331 to scrape off the copper shavings adhering to the corner of the extrusion groove.

[0032] Furthermore, a snap-fit ​​spring 322 is provided inside the shrinkage groove 321. The snap-fit ​​spring 322 is used to drive the telescopic block 320 to retract and reset the shrinkage groove 321. One end of the snap-fit ​​spring 322 is fixedly connected to the end of the shrinkage groove 321 away from the groove opening, and the other end of the snap-fit ​​spring 322 is fixedly connected to the centripetal end of the telescopic block 320.

[0033] It should be noted that the second drive roller 301 is driven to rotate by a motor. When each telescopic block 320 rotates synchronously with the extrusion roller 310, the centrifugal side of the telescopic block 320 contacts the lower side of the copper rod. Since the copper rod is conveyed by the conveying mechanism, its upper and lower sides are fixed, such as a roller-type clamping feeding mechanism. Therefore, under the extrusion action of the fixed copper rod, the telescopic block 320 in contact with the lower side of the copper rod is compressed back into the shrinkage groove 321. During this period, the engagement spring 322 is compressed and stores elastic potential energy. Under the action of the friction between the top of the telescopic block 320 and the bottom of the engagement arm 211, the copper rod moves axially and is bitten into the extrusion groove. After the telescopic block 320 rotates away from directly below the limiting wall 311, the telescopic block 320 retracted into the shrinkage groove 321 loses the pressing action of the copper rod. Under the action of the restoring force of the engagement spring 322, the telescopic block 320 extends out of the shrinkage groove 321 and resets.

[0034] exist Figures 8-10 In the middle, the scraping component 330 includes a trigger arc block 333 and a scraping straight block 332. The trigger arc block 333 and the scraping straight block 332 are fixedly connected to an anti-detachment baffle 334 on the side away from the extrusion groove. The anti-detachment baffle 334 is used to prevent the scraping straight block 332 from slipping out of the mounting groove 331.

[0035] Furthermore, a cleaning spring 335 is provided inside the mounting groove 331. One end of the cleaning spring 335 is fixedly connected to the side of the anti-detachment baffle 334 away from the extrusion groove, and the other end of the cleaning spring 335 is fixedly connected to the side of the mounting groove 331 away from the groove opening.

[0036] Furthermore, the orthographic projection of the trigger arc block 333 on the mounting groove 331 is located on the centrifugal side of the contraction groove 321, and the orthographic projection of the scraping straight block 332 on the mounting groove 331 is located between two adjacent contraction grooves 321. That is, when the telescopic block 320 extends out of the contraction groove 321, the telescopic block 320 can block the trigger arc block 333 located in the mounting groove 331 to prevent the scraping straight block 332 from extending out of the mounting groove 331.

[0037] Preferably, the radial side of the scraping block 332 slides against the periphery of the extrusion wheel 310 so that when the scraping block 332 extends out of the mounting groove 331, it scrapes away the copper shavings at the edges of the extrusion groove.

[0038] The triggering arc block 333 is arc-shaped on the side near the axis of the extrusion wheel 310. When the telescopic block 320 extends out of the shrinkage groove 321, the centrifugal side of the telescopic block 320 slides and fits against the centripetal side of the triggering arc block 333.

[0039] It needs to be disclosed that point A is the orthographic projection of the telescopic block 320 at its maximum distance from the axis onto the limiting wall 311, and the radius of point B coincides with the dividing line between the scraping straight block 332 and the trigger arc block 333.

[0040] When the telescopic block 320 is compressed back into the retraction groove 321 by the copper rod, the trigger arc block 333 loses the blocking effect of the telescopic block 320. The scraping straight block 332 is pushed out of the mounting groove 331 by the previously compressed cleaning spring 335. The centripetal side of the scraping straight block 332 slides along the centrifugal side of the extrusion roller 310, thereby scraping away the stubborn copper shavings adhering to the corners of the extrusion groove. After the telescopic block 320 moves away from directly under the biting arm 211, because the deformation restoring force of the biting spring 322 is greater than the deformation resistance of the cleaning spring 335, the extended telescopic block 320 slides along the centripetal side of the scraping straight block 332 towards the centrifugal side of the telescopic block 320, thereby pushing the trigger arc block 333 back into the mounting groove 331, thereby driving the scraping straight block 332 to retract into the mounting groove 331 simultaneously and compress the cleaning spring 335.

[0041] The core of this automated continuous copper busbar extrusion production device is to solve the initial bite problem of the copper rod through the telescopic block 320, and to clean the copper shavings from the edges of the extrusion groove through the scraper 330. The specific working principle is as follows: S1. Device Pre-processing and Adjustment: Before processing the copper busbar, the depth of the biting arm 211 pressed into the extrusion groove is adjusted according to the thickness parameters of the target copper busbar to determine the thickness of the copper busbar. During adjustment, the length of the piston rod extension of the hydraulic rod 202 is changed to drive the adjusting arm 201 to slide up and down, thereby driving the first drive roller 210 and the biting arm 211 to move up and down. The distance between the bottom of the biting arm 211 and the top of the extrusion groove is the thickness of the produced copper busbar.

[0042] S2. Initial Copper Rod Conveying and Triggering of Telescopic Block 320: The external conveying mechanism conveys the cylindrical copper rod to be extruded to the vicinity of the extrusion groove. At this time, the end of the copper rod is tangent to the bottom of the biting arm 211 and the top of the extrusion wheel 310, which can easily lead to jamming and slippage. The telescopic block 320 on the extrusion wheel 310 is in the extended state before the copper rod enters the extrusion groove. After the copper rod is conveyed to the position, the telescopic block 320 on its upstream side contacts the bottom of the copper rod, and the fixed copper rod is pressed back into the contraction groove 321. During this period, the biting spring 322 is compressed and stores elastic potential energy. The biting spring 322 is used to drive the retracted telescopic block 320 to reset.

[0043] S3. Copper rod biting and extrusion: The second drive roller 301 is driven to rotate by a motor, and the telescopic block 320 rotates synchronously with the extrusion roller 310. Under the friction between the top of the compressed telescopic block 320 and the bottom of the biting arm 211, the copper rod moves axially and bites into the extrusion groove. After the telescopic block 320 rotates away from directly below the limiting wall 311, the telescopic block 320, which has lost the pressure of the copper rod, extends and resets under the restoring force of the biting spring 322, continuously assisting the copper rod biting and conveying, and realizing continuous extrusion.

[0044] S4. Copper chip removal from the corner of the extrusion groove: The scraper 330 consists of a triggering arc block 333 and a scraping straight block 332. The anti-detachment baffle 334 prevents the scraping straight block 332 from slipping out of the mounting groove 331. The cleaning spring 335 provides the power for the scraping straight block 332 to extend, and works with the telescopic block 320 to realize the copper chip removal action.

[0045] S5. Linkage action of scraper 330: Triggering arc block 333 and telescopic block 320 cooperate accordingly, scraping straight block 332 is set to fit against extrusion wheel 310; when telescopic block 320 extends, it blocks triggering arc block 333 to prevent scraping straight block 332 from extending; when telescopic block 320 is compressed and retracted by copper rod, triggering arc block 333 loses its blocking, scraping straight block 332 extends under the elastic force of cleaning spring 335, slides along extrusion wheel 310 and scrapes away stubborn copper shavings at the corner of extrusion groove.

[0046] S6. Scraping component 330 reset: After the telescopic block 320 rotates away from directly below the biting arm 211, the restoring force of the biting spring 322 is greater than the deformation resistance of the cleaning spring 335. The extended telescopic block 320 will trigger the arc block 333 to push back into the mounting slot 331, causing the scraping straight block 332 to retract synchronously and compress the cleaning spring 335, completing the reset to wait for the next scraping action and ensuring stable squeezing.

[0047] In summary, this production device solves the problem of initial tangential jamming and slippage of copper rods by cooperating with the telescopic block 320 and the engagement spring 322, thus achieving automatic biting; through the linkage of the scraper 330, the cleaning spring 335, and the telescopic block 320, it automatically cleans the copper shavings on the edges of the extrusion groove, ultimately achieving automated, continuous, and efficient production of copper busbars.
