Description

Technical Field

[0001] This application relates to the field of copper busbar processing technology, and in particular to a turret punch press for punching copper busbars that is easy to clean. Background Technology

[0002] Copper busbars, also known as copper busbars or copper busbars, are long conductors made of copper with rectangular or chamfered rectangular cross-sections. They are used in circuits to transmit current and connect electrical equipment and are widely used in complete sets of power distribution equipment.

[0003] In the production of copper busbars, punching is required to meet the usage requirements. Currently, most copper busbar punching machines use turret punch presses. During operation, the feeder on the turret punch press clamps the copper busbar and moves it between the upper and lower dies. The upper die then presses downwards to complete the punching process.

[0004] Regarding the aforementioned technologies, the inventors discovered that during the stamping process of copper busbars using a turret punch press, the stamped copper slag is ejected into the lower die. Due to the small size of the lower die, it is difficult and time-consuming for workers to clean the copper slag regularly. Summary of the Invention

[0005] To alleviate the problem of difficult cleaning of the lower die of a turret punch press, this application provides a turret punch press for punching copper busbars that is easy to clean.

[0006] This application provides a turret punch press for punching copper busbars that is easy to clean, employing the following technical solution:

[0007] A turret punch press for easy cleaning of copper busbars includes a frame, an upper turret, a lower turret, and a cleaning mechanism. The upper turret is connected to the frame and has multiple upper dies. The lower turret is connected to the frame and has multiple lower dies. Each lower die has a die hole, and the lower dies correspond one-to-one with the upper dies. The cleaning mechanism includes a push assembly and multiple lifting plugs, each lifting plug corresponding one-to-one with the lower dies. Each lifting plug is slidably connected to the die hole of its corresponding lower die. The push assembly is connected to the lower turret, and the lifting plugs are all connected to the push assembly. The push assembly is used to push the lifting plugs to slide within the lower dies to which they are connected.

[0008] By adopting the above technical solution, a lifting plug is slidably connected inside each die hole. During the punching process of the copper busbar, when the copper slag inside the die hole accumulates to a certain amount, the push assembly is activated. The push assembly drives multiple lifting plugs to rise and fall synchronously, which can push the copper slag out of the die hole. Then the copper slag can be cleaned. There is no need for staff to clean the inside of each lower die separately, which improves the convenience of cleaning the turret punch press.

[0009] Preferably, each of the lifting plugs is slidably and sealed within its corresponding lower mold. The pushing assembly includes an air tank, an electric cylinder, and a pressure plate. The air tank is fixedly connected inside the lower turntable. Multiple air outlet pipes are connected to the air tank, and each air outlet pipe is correspondingly arranged with one of the lower molds. The end of each air outlet pipe away from the air tank is connected to a mold hole opened in its corresponding lower mold. The connection between the air outlet pipe and the mold hole is lower than the bottom of the lifting plug. The electric cylinder is fixedly connected to the air tank, and the pressure plate is slidably and sealed within the air tank. The piston rod of the electric cylinder is connected to the pressure plate to drive the pressure plate to rise and fall.

[0010] By adopting the above technical solution, the piston rod of the electric push cylinder can be extended and retracted to drive the air pressure plate to slide, so that the air pressure plate can press the air in the air storage box into multiple mold holes through multiple air outlet pipes, and then push multiple lifting plugs to move synchronously to clean the copper slag in the lower mold.

[0011] Preferably, each of the lower molds is provided with a scraping mechanism, which includes a power component and a scraping plate. The scraping plate is rotatably connected to the lifting plug connected to the lower mold. The power component is connected to the lower turntable and is connected to the scraping plate. The power component is used to drive the scraping plate to rotate.

[0012] By adopting the above technical solution, after the copper slag in multiple mold holes is pushed out by the lifting plug, the lifting plug continues to slide outward, so that the scraping plate on the lifting plug can abut against the bottom surface of the upper mold. Then the power component drives the scraping plate to rotate, so that the scraping plate can remove the copper slag adhering to the upper mold, thereby improving the convenience of cleaning the upper mold.

[0013] Preferably, the lifting plug has a vent hole, the power assembly includes a rotating rod and a fan blade, the rotating rod is rotatably connected to the lifting plug, the fan blade is coaxially fixedly connected to the rotating rod, and both the rotating rod and the fan blade are located within the vent hole; the exhaust pipe is connected to a first exhaust pipe and a second exhaust pipe, the end of the first exhaust pipe away from the exhaust pipe is connected to the interior of the die hole, the first exhaust pipe is provided with a first control valve, the end of the second exhaust pipe away from the exhaust pipe is connected to the vent hole, the vent hole is a retractable hose, and the second exhaust pipe is provided with a second control valve.

[0014] By adopting the above technical solution, when it is necessary to clean the copper slag inside the mold hole, the first control valve is opened and the second control valve is closed, so that the gas in the gas storage tank can be forced into the mold hole, smoothly driving the lifting plug to slide and clean the mold hole of the lower mold. When it is necessary to clean the copper slag on the bottom surface of the upper mold, the lifting plug is driven to the top of the mold hole and the scraper plate contacts the bottom of the lower mold. Then, the first control valve is closed and the second control valve is opened, and air is continued to be compressed into the vent hole through the air pressure plate. The gas flowing in the vent hole will drive the fan blade inside the vent hole to rotate. The rotation of the fan blade will drive the rotating rod fixedly connected to it to rotate, which in turn drives the scraper plate to rotate, so that the scraper plate can scrape and clean the copper slag adhering to the upper mold, ensuring the convenience of cleaning the upper mold.

[0015] Preferably, the air compressor plate is connected to an air vent pipe, and an electromagnetic valve is installed on the air vent pipe.

[0016] By adopting the above technical solution, by using the setting of the vent pipe, closing the solenoid valve, and pushing the pressure plate to slide, the gas can be smoothly pressed into the mold hole. When it is necessary to replenish the gas in the gas storage tank, the solenoid valve is opened and the pressure plate is moved back, so that external air can enter the gas storage tank to replenish the gas in the gas storage tank.

[0017] Preferably, a protective sleeve is fitted on the outside of each lifting plug, the protective sleeve is rotatably connected to the outside of the lifting plug, the protective sleeve is fixedly connected to the rotating rod, the top of the protective sleeve has multiple air vents, and a sealing component is provided on the protective sleeve for sealing the multiple air vents.

[0018] By adopting the above technical solution, the protective cylinder is used to seal the copper busbar during normal stamping, reducing the possibility of copper slag falling into the vent hole. During the cleaning of the upper mold, the vent hole on the protective cylinder is opened, and the pressure plate is pressed down to drive the fan blade to rotate and drive the scraper plate to rotate. At the same time, the gas can be discharged from the vent, thereby blowing air to cool the upper mold and achieving rapid cooling of the upper mold.

[0019] Preferably, the sealing assembly includes a sealing plate, a spring, and a push rod. The push rod passes through the protective cylinder and is slidably connected to the protective cylinder. The sealing plate is slidably connected inside the protective cylinder. Multiple sealing blocks are fixedly connected to the sealing plate, and each sealing block corresponds to one of the multiple vent holes. The spring is disposed between the sealing plate and the protective cylinder. The spring is used to pull the sealing block on the sealing plate into its corresponding vent hole. When the scraping plate abuts against the upper mold, the push rod, under the pressure of the upper mold, causes the sealing block to be pulled out from the vent hole.

[0020] By adopting the above technical solution, when the copper busbar is stamped, multiple sealing blocks on the sealing plate are inserted into multiple vent holes under the pull of springs, sealing the multiple vent holes. When the upper mold needs to be cleaned, the gas in the lower gas storage box drives the lifting plug to move upward. During this process, the push rod will first abut against the upper mold, and then continue to drive the lifting plug to move upward, so that the push rod can slide into the protective cylinder, thereby causing the sealing plate to descend inside the protective cylinder, so that the multiple vent holes open automatically, improving the convenience of sealing and opening multiple vent holes.

[0021] Preferably, a support platform is rotatably connected to the frame, the lower turntable is connected to the support platform, the rotation axis of the support platform is perpendicular to the rotation axis of the lower turntable, and a drive assembly is provided on the worktable, the drive assembly being connected to the support platform to drive the support platform to rotate.

[0022] By adopting the above technical solution, the support platform is rotatably connected to the worktable. After the copper slag is pushed out of the mold hole of the lower mold, the drive component is activated. The drive component drives the support platform to rotate, which in turn causes the lower turntable to tilt a certain distance, thereby facilitating the copper slag to slide off the lower turntable and improving the convenience of cleaning the copper slag on the lower turntable.

[0023] Preferably, the drive assembly includes a third motor and two gears. The third motor is fixedly connected to the worktable. One of the gears is coaxially fixedly connected to the main shaft of the third motor, and the other gear is fixedly connected to the support platform. The rotation axis of the gear fixedly connected to the support platform is collinear with the rotation axis of the support platform, and the two gears are meshed together.

[0024] By adopting the above technical solution, the third motor is started, and the rotation of the main shaft of the third motor drives the gear fixedly connected to it to rotate. The rotation of the gear will drive another gear to rotate, thereby rotating the support platform and realizing the adjustment of the angle of the lower turntable.

[0025] In summary, this application includes at least the following beneficial technical effects:

[0026] 1. By sliding and connecting lifting plugs inside each die hole, when the copper slag inside the die hole accumulates to a certain amount during the punching process of the copper busbar, the push assembly is activated. The push assembly drives multiple lifting plugs to rise and fall synchronously, so that the lifting plugs can push out the copper slag inside the die hole. Then the copper slag can be cleaned. There is no need for staff to clean the inside of each lower die separately, which improves the convenience of cleaning the turret punch.

[0027] 2. By using the lifting plug to push out the copper slag in multiple mold holes, and then continuing to slide the lifting plug outward, the scraper on the lifting plug can be brought into contact with the bottom surface of the upper mold. Then the power unit drives the scraper to rotate, so that the scraper can remove the copper slag adhering to the upper mold, thus improving the convenience of cleaning the upper mold.

[0028] 3. By rotating the support platform onto the worktable, after the copper slag is pushed out of the die hole of the lower mold, the drive assembly is activated. The drive assembly drives the support platform to rotate, which in turn causes the lower turntable to tilt a certain distance, making it easier for the copper slag to slide off the lower turntable and improving the convenience of cleaning the copper slag on the lower turntable.

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0042] This application discloses a turret punch press for punching copper busbars that is easy to clean.

[0043] Example 1

[0044] Reference Figure 1 and Figure 2 A turret punch press for punching copper busbars, which is easy to clean, includes a frame 100. A worktable 110 is fixedly connected to the frame 100 and is horizontally positioned. An upper turntable 200 is rotatably connected to the frame 100, and a first motor is fixedly connected to the frame 100. The spindle of the first motor is coaxially fixedly connected to the upper turntable 200 to drive the upper turntable 200 to rotate. Multiple upper dies 210 are mounted on the upper turntable 200, and the multiple upper dies 210 are arranged at intervals with the axis of the upper turntable 200 as the center.

[0045] Reference Figure 2 and Figure 3A lower turntable 300 is mounted on the frame 100, and multiple lower dies 310 are mounted on the lower turntable 300. The lower dies 310 are spaced apart with the axis of the lower turntable 300 as the center. Each lower die 310 corresponds to one upper die 210. The upper dies 210 can punch downwards to punch holes in the copper busbars. A feeder 120 is mounted on the worktable 110. The feeder 120 can clamp the copper busbars and transport them between the upper dies 210 and the lower dies 310. A cleaning mechanism 400 is mounted on the lower turntable 300 to clean the copper slag inside the lower dies 310. When punching holes in the copper busbars is required, the feeder 120 clamps the copper busbars, then feeds them between the lower dies 310 and the upper dies 210, and then the upper dies 210 are activated to punch the copper busbars.

[0046] Reference Figure 2 , Figure 3 and Figure 4 Each lower mold 310 has a corresponding die hole 320 on its upper mold 210. When punching the steel strip, the upper mold 210 can be inserted into the die hole 320 of the lower mold 310 by pressing downwards, and the copper slag on the steel strip is pressed into the die hole 320. The cleaning mechanism 400 includes multiple lifting plugs 410, which are arranged one-to-one with multiple lower molds 310. Each lifting plug 410 is slidably connected to the die hole 320 of its corresponding lower mold 310. A push assembly 420 is installed on the lower turntable 300. The push assembly 420 is used to push the slidingly connected lifting plug 410 in each die hole 320 outwards.

[0047] Reference Figure 5 , Figure 6 and Figure 7 Each lifting plug 410 is sealed and slidably connected within its corresponding lower mold 310 mold hole 320. The pushing assembly 420 includes an air storage box 421 fixedly connected within the lower turntable 300. Multiple air outlet pipes 422 are connected to the air storage box 421. The multiple air outlet pipes 422 are arranged one-to-one with the multiple mold holes 320. The end of each air outlet pipe 422 away from the air storage box 421 is connected to the interior of its corresponding mold hole 320. The connection between the air outlet pipe 422 and the mold hole 320 is located between the bottom of the mold hole 320 and the lifting plug 410.

[0048] An electric cylinder 423 is fixedly connected to the top wall of the gas storage tank 421. The piston rod of the electric cylinder 423 passes through the top wall of the gas storage tank 421 and is fixedly connected to a pressure plate 424. The pressure plate 424 is slidably connected inside the gas storage tank 421. A vent pipe 425 is fixedly connected to the pressure plate 424. A solenoid valve 426 is installed on the vent pipe 425. The solenoid valve 426 is used to control the opening and closing of the vent pipe 425. Utilizing the sealing and sliding mechanism of the lifting plugs 410, after punching the copper busbars, the copper slag produced during punching falls into the die holes 320. Once a certain amount accumulates, the electric pusher cylinder 423 is activated. The electric pusher cylinder 423 drives the pressure plate 424 downwards, forcing the gas in the gas storage tank 421 below the pressure plate 424 into multiple die holes 320. This pushes multiple lifting plugs 410 upwards, causing the lifting plugs 410 to push the copper slag out of the die holes 320. The staff can then clean the copper slag on the lower turntable 300, eliminating the need for individual cleaning of the interior of each lower mold 310, thus improving the convenience of cleaning the turret punch. At the same time, by utilizing the vent pipe 425, when it is necessary to replenish the gas between the pressure plate 424 and the bottom of the air storage tank 421, the solenoid valve 426 can be opened to allow gas to enter the space between the pressure plate 424 and the bottom of the air storage tank 421 through the vent pipe 425, thereby replenishing the gas in the air storage tank 421.

[0049] Reference Figure 2 , Figure 7 and Figure 8 During the punching process of the copper busbar by the upper mold 210, the upper mold 210 will heat up under the action of compressed air and friction, and copper slag will easily adhere to it. If the copper slag on the upper mold 210 is not cleaned in time, it will affect the punching of the copper busbar.

[0050] To facilitate the cleaning of copper slag adhering to the upper mold 210, each lower mold 310 is equipped with a scraping mechanism 500. Each scraping mechanism 500 includes a vent 411 opened on the lifting plug 410. The vent 411 is vertically arranged, and its axis is collinear with the vertical axis of the lifting plug 410. A rotating rod 520 is coaxially inserted into the vent 411. The rotating rod 520 is rotatably connected to the lifting plug 410. One end of the rotating rod 520 extending upward from the lifting plug 410 is fixedly connected to a support plate 511. The support plate 511 is horizontally arranged, and a scraping plate 530 is fixedly connected to the support plate 511. The scraping plate 530 is vertically arranged. The rotating rod 520 can drive the scraping plate 530 to rotate to scrape off the copper slag adhering to the upper mold 210. A power assembly 510 is installed on the lower turntable 300. The power assembly 510 is used to start the rotating rod 520 to rotate, thereby driving the scraper 530 to rotate.

[0051] Reference Figure 7 and Figure 8The power assembly 510 includes multiple fan blades 540, each corresponding to a multiple rotating rod 520. Each fan blade 540 is coaxially fixedly connected to its corresponding rotating rod 520, with the fan blade 540 facing the air inlet end of the vent 411. Each exhaust pipe 422, after entering the mold hole 320, is connected to a first exhaust pipe 550 and a second exhaust pipe 560. The end of the first exhaust pipe 550 away from the exhaust pipe 422 is connected to the interior of the mold hole 320. A first electric control valve is installed on the first exhaust pipe 550, controlling its opening and closing. The second exhaust pipe 560 is a retractable flexible hose. The end of the second exhaust pipe 560 away from the exhaust pipe 422 is connected to the interior of the vent 411 opened by its corresponding lifting plug 410. A second control valve 580 is installed on the second exhaust pipe 560, controlling its opening and closing. When it is necessary to push out the copper slag in each die hole 320 of the lower die 310, close the second control valve 580 and open the first control valve 570. This allows the air pressure plate 424 to force the air in the air storage box 421 into the multiple die holes 320, thus smoothly pushing the copper slag out of the die holes 320 and cleaning the copper slag inside the die holes 320. When it is necessary to clean the copper slag adhering to the upper die 210, first open the first control valve 570 and close the second control valve 580. Then start the electric push cylinder 423, which will push the air pressure plate 424 down to supply air into the multiple die holes 320, allowing the scraper plate 530 to move with the rising and falling piston 4. 10 moves upward, then the scraper plate 530 contacts the bottom of the lower mold 310, then the first control valve 570 is closed, the second control valve 580 is opened, and the electric push cylinder 423 continues to drive the air pressure plate 424 downward, so that the gas can enter the vent hole 411 opened by the lifting plug 410 through the second exhaust pipe 560. The gas flowing in the vent hole 411 will drive the fan blade 540 inside the vent hole 411 to rotate. The rotation of the fan blade 540 will drive the rotating rod 520 fixedly connected to it to rotate, which in turn drives the scraper plate 530 to rotate, so that the scraper plate 530 can scrape and clean the copper slag adhering to the upper mold 210, improving the convenience of cleaning the upper mold 210.

[0052] Reference Figure 3 and Figure 4 To further improve the cleaning of steel slag ejected from the lower turntable 300, a support platform 600 is installed on the frame 100. The lower turntable 300 is rotatably connected to the support platform 600. A second motor is fixedly connected inside the support platform 600, and the main shaft of the second motor is coaxially fixedly connected to the lower turntable 300. The support platform 600 is rotatably connected to the worktable 110, and the rotation axis of the support platform 600 is perpendicular to the rotation axis of the lower turntable 300. A drive assembly 610 is installed on the worktable 110 to drive the support platform 600 to rotate.

[0053] The drive assembly 610 includes a third motor 611 fixedly connected to the worktable 110. A gear 612 is coaxially fixedly connected to the main shaft of the third motor 611. Another gear 612 is fixedly connected to the support platform 600. The gear 612 fixedly connected to the support platform 600 drives the rotation axis to be collinear with the rotation axis of the support platform 600, and the two gears 612 mesh with each other. Utilizing the rotational setting of the support platform 600, after pushing the copper slag in the die holes 320 of each lower die 310 upwards, the third motor 611 is started. The rotation of the main shaft of the third motor 611 drives the coaxially fixed gear 612 to rotate. Through the cooperation of the two gears 612, the support platform 600 is rotated, thereby tilting the lower turntable 300 at a certain angle, allowing the copper slag on the lower turntable 300 to slide smoothly off, further improving the convenience of cleaning the copper busbar punching machine.

[0054] The implementation principle of a turret punch press for easy cleaning of copper busbars according to an embodiment of this application is as follows: By sealing the sliding lifting plug 410 in the die hole 320 of each lower die 310, when the waste generated by punching the copper busbar accumulates to a certain amount in the die hole 320, the first control valve 570 is opened and the second control valve 580 is closed. Then, the electric push cylinder 423 is activated to force the gas in the gas storage tank 421 into the die holes 320 of multiple lower dies 310, thereby pushing the lifting plug 410 in the die hole 320 upward, so that the lifting plug 410 pushes the copper slag in the die hole 320 out of the die hole 320. Then, the operator can clean the copper slag on the lower turntable 300. Each lower die 310 needs to be cleaned individually by staff to improve the convenience of cleaning the turret punch. At the same time, by using the scraper 530, after the scraper 530 is pushed out of the die hole 320 with the lifting plug 410, the first control valve 570 is closed, the second control valve 580 is opened, and the air pressure plate 424 is pressed down. This allows the gas to enter the vent hole 411 opened by the lifting plug 410 through the second exhaust pipe 560. Driven by the fan blade 540, the scraper 530 is rotated, which allows the scraper 530 to scrape and clean the copper slag adhering to the upper die 210, further improving the convenience of cleaning the upper die 210.

[0055] Example 2

[0056] Reference Figure 9 and Figure 10The difference between this embodiment and embodiment 1 is that, in order to cool down the upper mold 210 while cleaning it, a protective cylinder 700 is sleeved on the outside of each lifting plug 410. The protective cylinder 700 is located at the top of the lifting plug 410 and is rotatably connected to the lifting plug 410. The protective cylinder 700 is fixedly connected to the rotating rod 520, and the scraping plate 530 is fixedly connected to the top of the protective cylinder 700.

[0057] Reference Figure 10 and Figure 11 The top of the protective cylinder 700 is provided with multiple air vents 710, which are spaced apart with the rotation axis of the protective cylinder 700 as the center. A sealing assembly 720 is installed on the protective cylinder 700 to seal the multiple air vents 710. The sealing assembly 720 includes two push rods 721 that pass through the top of the protective cylinder 700. Both push rods 721 are vertically arranged and slidably connected to the protective cylinder 700. One end of the push rod 721 that passes inside the protective cylinder 700 is fixedly connected to a sealing plate 722. The sealing plate 722 is horizontally arranged and has multiple sealing blocks 723 fixedly connected to it. The multiple sealing blocks 723 are arranged one-to-one with multiple vent holes 710. A spring 724 is installed on the sealing plate 722. One end of the spring 724 is fixedly connected to the sealing plate 722, and the other end of the spring 724 is fixedly connected to the top of the protective cylinder 700. The spring 724 applies an upward pulling force to the sealing plate 722 so that the sealing blocks 723 on the sealing plate 722 block the vent holes 710. After the sealing blocks 723 block the vent holes 710, the top height of the push rod 721 is higher than the height of the scraping plate 530. During the stamping of the copper busbar, multiple sealing blocks 723 on the sealing plate 722 are inserted into multiple vent holes 710 under the pull of the spring 724, sealing the multiple vent holes 710 and reducing the possibility of waste entering the vent hole 411; when it is necessary to clean the copper slag adhering to the bottom of the upper mold 210, the push rod 721 will first abut against the upper mold 210 during the process of driving the lifting plug 410 to move upward so that the scraper 530 abuts against the upper mold 210, and then continue to drive. When the lifting plug 410 moves upward, the push rod 721 slides into the protective cylinder 700, causing the sealing plate 722 to descend inside the protective cylinder 700, opening multiple air outlets 710. Then, the pressure plate 424 continues to press down, forcing the gas in the air storage box 421 outward. During the process of driving the fan blade 540 to rotate and driving the scraper plate 530 to rotate, the gas can be discharged from the air outlet at the same time, thereby blowing air to cool the upper mold 210 and achieving rapid cooling of the upper mold 210.

[0058] The implementation principle of a turret punch press for easy cleaning of copper busbars in this application embodiment is as follows: by rotating the protective cylinder 700 on the lifting plug 410, during the cleaning of the upper mold 210, the gas in the air storage box 421 is forced out by the air pressure plate 424 into the air vent 411.
