The punching device for this new energy busbar uses two clamping components to push several clamping rollers inside two connecting frames to clamp the two sides of the busbar. Then, a hydraulic cylinder pushes a punching cutter downwards to punch the busbar. During the downward punching process, the pushing component pushes the first hydraulic push rod downwards, thereby inputting hydraulic oil into several second hydraulic push rods. This causes the second hydraulic push rods to simultaneously push the limiting rack towards the limiting gear, causing the limiting rack to lock onto the limiting gear and restrict the rotation of the clamping rollers. This ensures stable clamping of the busbar during punching. After punching, as the hydraulic cylinder retracts, the pushing component is pulled up, and the first hydraulic push rod is also pulled up. This causes the several second hydraulic push rods to retract simultaneously, pulling the limiting rack back and disengaging it from the limiting gear. This allows the busbar to be moved horizontally and removed without the need for repeated tightening and loosening of the clamping components, making operation convenient and improving processing efficiency.

[0018] 2. The punching device for this new energy busbar can easily guide and push the busbar by clamping it left and right with several clamping rollers.

[0024] As an optional technical solution of this utility model: the pushing component includes a spring baffle 15 fixedly connected to the outer wall of the telescopic rod of the hydraulic cylinder 3, and the pushing component also includes a pushing frame 5 slidably connected to the outer wall of the telescopic rod of the hydraulic cylinder 3.

The interior of the two slide rails 7 is slidably connected to the top ends of the two first hydraulic push rods 13 respectively. When the telescopic rod of the hydraulic cylinder 3 is pressed down, the spring baffle 15 can be pressed down to push the thrust spring 6, which in turn causes the pushing frame 5 to be pressed down, thereby causing the two slide rails 7 to press down the two first hydraulic push rods 13. The sliding is guided by the slide rails 7, which can adapt to the clamping adjustment of the connecting frame 11.

[0025] As an optional technical solution of this utility model: the thrust spring 6 is sleeved on the outer wall of the telescopic rod of the hydraulic cylinder 3.

The distance between the two guide channels 8 is adapted to the sum of the lengths of the two sliding arms 10. By rotating the drive screw 9, the sliding arms 10 can be driven to clamp left and right, thereby realizing the left and right clamping of the two connecting frames 11.

[0027] As an optional technical solution of this utility model: a through opening 21 is provided at the center of the bottom of the support column 2, the through opening 21 corresponds to the position between the two connecting frames 11, and a guide bucket 14 is fixedly connected to the bottom of the outer side of the support column 2. The guide bucket 14 corresponds to the through opening 21, and the width of the inner wall of the guide bucket 14 is greater than the width of the through opening 21. The confluence drain can be pushed backward out of the clamping roller shaft 17 and pass through the support column 2, and then guided down and discharged by the guide bucket 14.

[0029] The working process of this utility model is as follows: When the user uses it... 1) The two clamping components push the clamping rollers 17 inside the two connecting frames 11 left and right to clamp the two sides of the busbar; 2) Then, the hydraulic cylinder 3 pushes the punching cutter 4 down. During the punching process, the pushing component pushes the first hydraulic push rod 13 down, thereby inputting hydraulic oil into several second hydraulic push rods 18. This causes several second hydraulic push rods 18 to push the limiting rack 19 towards the limiting gear 20, so that the limiting rack 19 clamps the limiting gear 20, restricting the rotation of the clamping roller shaft 17, thereby ensuring stable clamping of the manifold during punching. 3) After punching is completed, as the hydraulic cylinder 3 is pulled back, the pushing component is pulled up, and the first hydraulic push rod 13 is pulled up. Then, several second hydraulic push rods 18 are pulled back in sync, and the limiting rack 19 is pulled back to disengage from the limiting gear 20. Then, the busbar can be horizontally pushed to move its position and the busbar can be pushed out.

[0030] In summary, this utility model utilizes two clamping components to push several clamping rollers 17 inside the two connecting frames 11 to clamp the manifold on both sides. Then, a hydraulic cylinder 3 pushes a punching cutter 4 downwards to punch the manifold. During the punching process, the pushing component pushes the first hydraulic push rod 13 downwards, thereby inputting hydraulic oil into several second hydraulic push rods 18. These second hydraulic push rods 18 simultaneously push the limiting rack 19 towards the limiting gear 20, causing the limiting rack 19 to engage with the limiting gear 20, restricting the rotation of the clamping rollers 17. This ensures stable clamping of the manifold during punching. After punching, as the hydraulic cylinder 3 retracts, the pushing component is pulled up, and the first hydraulic push rod 13 is pulled up. Then, several second hydraulic push rods 18 are pulled back simultaneously, which in turn pulls the limiting rack 19 back and disengages it from the limiting gear 20. This allows the busbar to be moved horizontally and removed without the need for repeated tightening and loosening of the clamping components. This makes operation convenient and improves processing efficiency. The left and right clamping of several clamping rollers 17 can easily guide the pushing of the busbar. After processing, the next busbar can be pushed in directly, and the punched busbar can be ejected for continuous processing, thus improving processing efficiency.
