Description

Technical Field

[0001] This utility model relates to the field of copper busbar punching and shearing technology, and in particular to a punching and shearing device for a copper busbar production line. Background Technology

[0002] Copper busbars are long conductors made of copper, typically with a rectangular or chamfered (rounded) rectangular cross-section. They are mainly used for transmitting current and connecting electrical equipment. In distribution cabinets, copper busbars are commonly used for the U, V, W phases and the PE busbar. Their surfaces are coated with phase-colored paint for differentiation. The punching and shearing process in copper busbar production refers to the operation of punching and shearing holes in the copper busbar using mechanical equipment. This is mainly used to process the holes in the copper busbar and cut off excess parts to meet the connection requirements of electrical equipment. An existing busbar punching and shearing device (publication number: CN219632462U) uses a blowing fan to blow the debris or scrap generated during the punching and shearing process into a waste collection box, thereby achieving the purpose of collecting the debris or scrap generated during the punching and shearing process for subsequent cleaning by staff. Although multiple blowing fans can be used to blow away the waste, the airflow blown by the fans is scattered and undirected, and cannot accurately guide the debris generated during punching and shearing to the waste collection box. This results in a large amount of debris flying everywhere, which not only pollutes the working environment, but also easily remains in critical parts of the equipment. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a punching and shearing device for a copper busbar production line.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A punching and shearing device for a copper busbar production line includes a support platform and a protective box. A cylinder is mounted on the upper center of the protective box via fasteners. A punching and shearing head is fixed on the output shaft of the cylinder. A limit groove is formed on the inner side wall of the protective box, and a crossbar is slidably mounted on the limit groove. An air nozzle is mounted on the upper end of the crossbar via fasteners. A fan device is fixedly mounted on the outer side wall of the protective box. The fan device is fixedly connected to the air nozzle via a corrugated pipe, and the corrugated pipe passes through and connects to the protective box. A dust suction port is formed on the support platform, and a collection box is provided below the support platform. A fixing pipe is fixed between the bottom end of the dust suction port and the collection box. An intercepting filter frame is embedded in the collection box, and a dust suction fan is provided below the collection box.

[0005] As a further embodiment of this utility model, a visible door panel is installed on the outer wall of the protective box away from the fan device via a hinge. The protective box is provided with two sets of fixing frames inside, and a pressure frame is provided between the two sets of fixing frames. The two sets of fixing frames are fixedly connected to the support platform.

[0006] As a further embodiment of this utility model, a screw is movably provided inside the fixing frame, a motor is fixed to the top of the fixing frame, the motor is fixedly connected to the screw through an output shaft, a screw block is threadedly installed on the screw, and the clamping frame is fixedly connected to the outer wall of the screw block through a connecting block.

[0007] As a further embodiment of this utility model, a control panel is fixedly provided on the outer wall of the protective box, and an electric push rod is fixedly provided on the side of the protective box near the fan device.

[0008] As a further embodiment of this utility model, the electric push rod is fixedly connected to the crossbar via an output shaft, and the electric push rods are symmetrically distributed on the protective box.

[0009] As a further embodiment of this utility model, the limiting grooves are symmetrically distributed inside the protective box, the vacuum cleaner is mounted on the support platform by fasteners, a sealing plate is installed on the collection box by hinges, and a fixing pipe is fixed between the bottom of the collection box and the vacuum cleaner.

[0010] Compared with the prior art, the present invention has the following beneficial effects: During the punching and shearing process of copper busbars, a system consisting of a crossbar, air nozzles, a collection box, an intercepting filter frame, a dust extraction fan, and an electric push rod is used. After punching and shearing, the electric push rod drives the crossbar to move the air nozzles, blowing away the debris accumulated on the surface of the copper busbar and directing it towards the dust extraction port. The dust extraction fan starts simultaneously, creating a stable and continuous suction force at the dust extraction port. When dealing with larger sheet-like waste, the airflow from the air nozzles provides sufficient thrust to detach it, while the negative pressure and strong suction force at the dust extraction port quickly pull it into the collection channel. The two work together to improve the debris collection efficiency. The debris captured by the negative pressure enters the collection box with the airflow and finally flows through the built-in intercepting filter frame, where it is collected uniformly. This effectively prevents debris residue in the punching and shearing area from affecting the accuracy of subsequent copper busbar punching and shearing, ensuring the processing quality of the copper busbars after punching and shearing.

[0015] Reference Figures 1-6A punching and shearing device for a copper busbar production line includes a support platform 1 and a protective box 2. A cylinder 203 is installed at the center of the upper end of the protective box 2 by fasteners. A punching and shearing head 8 is fixed on the output shaft of the cylinder 203. A limit groove 5 is opened on the inner side wall of the protective box 2. A crossbar 4 is slidably provided on the limit groove 5. An air nozzle 401 is installed at the upper end of the crossbar 4 by fasteners. A fan device 403 is fixedly installed on the outer side wall of the protective box 2. The fan device 403 is fixedly connected to the air nozzle 401 through a corrugated pipe 402, and the corrugated pipe 402 passes through and connects to the protective box 2. A dust suction port 601 is opened on the support platform 1. A collection box 6 is provided below the support platform 1. A fixing pipe 602 is fixed between the bottom end of the dust suction port 601 and the collection box 6. An intercepting filter frame 603 is embedded in the collection box 6. A dust suction fan 605 is provided below the collection box 6.

[0016] By operating the control panel 202, the motors 303 on both sides are started, driving the corresponding screws 305 to rotate via the output shaft. Simultaneously, the two sets of screw blocks 302 drive the corresponding connecting blocks 304 downwards, thereby causing the clamping frame 301 to move downwards and clamp the copper busbar. Then, the cylinder 203 is started, driving the punching and shearing head 8 downwards via the output shaft to punch and shear the clamped copper busbar. After the punching and shearing operation is completed, the clamping frame 301 returns to its original position, releasing the clamping state on the copper busbar. The electric push rod 7 then starts working, driving the crossbar 4 to move the air nozzle 401 along the limit groove 5 to the corresponding position where the punching and shearing produces debris. The fan device 403 is activated simultaneously, causing the air nozzle 401 to blow out airflow, which blows away the debris attached to the surface of the copper busbar and scattered in the punching and shearing area, and blows it towards the dust suction port 601. During this process, the dust suction fan 605 is activated simultaneously, which generates a stable and continuous negative pressure suction force at the dust suction port 601, which quickly sucks the debris blown by the air nozzle 401 into the dust suction channel. Then, the debris adsorbed by the negative pressure enters the collection box 6 along the fixed pipe 602 with the airflow. When it flows through the intercepting filter frame 603, the debris is intercepted by the intercepting filter frame 603. Finally, the visible door panel 201 is opened, and the punched and sheared copper busbar can be taken out from the punching and shearing area.

[0017] In this embodiment, a visible door panel 201 is installed on the outer wall of the protective box 2 away from the fan device 403 via a hinge. The protective box 2 is provided with two sets of fixing frames 3, and a pressure frame 301 is provided between the two sets of fixing frames 3. The two sets of fixing frames 3 are fixedly connected to the support platform 1.

[0018] When the electric push rod 7 drives the crossbar 4 to move the air nozzle 401 along the limiting groove 5, the limiting groove 5 provides stable guidance for the movement of the crossbar 4, ensuring that it can be accurately aligned with the punching and shearing debris area.

[0019] In this embodiment, a screw 305 is movably installed inside the fixed frame 3, and a motor 303 is fixed to the top of the fixed frame 3. The motor 303 is fixedly connected to the screw 305 through an output shaft. A screw block 302 is installed on the screw 305 through threads. The clamping frame 301 is fixedly connected to the outer wall of the screw block 302 through a connecting block 304.

[0020] The fan device 403 mainly consists of components such as a motor, a rotating rod, and fan blades. The motor drives the fan blades to rotate and generate airflow, which is then transmitted to the air nozzle 401 via the bellows 402.

[0021] In this embodiment, a control panel 202 is fixedly provided on the outer wall of the protective box 2, and an electric push rod 7 is fixedly provided on the side of the protective box 2 near the fan device 403.

[0022] The interceptor filter frame 603 is equipped with a filter screen, which can effectively intercept debris when it enters the collection box 6 with the airflow, thus achieving separation of debris and airflow.

[0023] In this embodiment, the electric push rod 7 is fixedly connected to the crossbar 4 through the output shaft, and the electric push rod 7 is symmetrically distributed on the protective box 2.

[0024] The visual door panel 201 can close off the protective area during punching and shearing operations to prevent debris from flying and ensure operational safety, while also allowing operators to observe the punching and shearing status of the internal copper busbar in real time.

[0025] In this embodiment, the limiting grooves 5 are symmetrically distributed inside the protective box 2, the vacuum fan 605 is installed on the support platform 1 by fasteners, the collection box 6 is fitted with a sealing plate 606 by a hinge, and a fixing pipe 604 is fixed between the bottom of the collection box 6 and the vacuum fan 605.

[0026] By opening the sealing plate 606, the intercepting filter frame 603 can be pulled out, thereby processing the debris collected inside the intercepting filter frame 603.

[0027] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When performing punching and shearing operations on the copper busbar, the visible door panel 201 is opened, and the copper busbar to be processed is placed below the clamping frame 301. By operating the control panel 202, the motor 303 is started, causing the screw 305 to rotate. At the same time, the screw block 302 drives the connecting block 304 to move downward, thereby causing the clamping frame 301 to move downward and press the copper busbar, preventing the copper busbar from shifting during the punching and shearing process. Then, the cylinder 203 is started, and the cylinder 203 drives the punching and shearing head 8 to move downward through the output shaft to punch and shear the clamped copper busbar. After the punching and shearing operation is completed, the clamping frame 301 is reset upward, releasing the clamping state on the copper busbar. The electric push rod 7 starts to work, driving the crossbar 4 to drive the air nozzle 401 along the limiting groove. 5. Move to the corresponding position where the punching and shearing generated debris. The fan device 403 starts simultaneously, causing the air nozzle 401 to blow out airflow, blowing away the debris attached to the surface of the copper busbar and scattered in the punching and shearing area, and blowing it towards the dust suction port 601. During this process, the dust suction fan 605 starts simultaneously, creating a stable and continuous negative pressure suction force at the dust suction port 601, which quickly sucks the debris blown by the air nozzle 401 into the dust suction channel. Then, the debris adsorbed by the negative pressure enters the collection box 6 along the fixed pipe 602 with the airflow. When it flows through the intercepting filter frame 603, the debris is intercepted by the intercepting filter frame 603. Finally, open the visible door panel 201 to remove the punched and sheared copper busbar from the punching and shearing area. By opening the sealing plate 606, the intercepting filter frame 603 of the collection box 6 can be pulled out to clean the collected debris.
