Description

Technical Field

[0001] This utility model relates to the field of copper busbar processing technology, specifically a fixed-length hydraulic shearing device for copper busbar processing. Background Technology

[0002] Copper busbars, also known as copper busbars, are long conductors made of high-purity copper. They typically have a rectangular or rounded rectangular cross-section and possess high conductivity, mechanical strength, and corrosion resistance. Their standard specifications comply with national standards such as GB / T5585.1-2005, ensuring stable product performance. They are widely used in high and low voltage switchgear, busbar trunking, and other applications, handling high current transmission in circuits.

[0003] Existing copper busbars require transfer equipment for shearing after the drawing process. During shearing, the copper busbar is in a conveying state, which easily causes the cut of the copper busbar to be inclined, thus affecting the shearing quality. Therefore, it does not meet the existing requirements. To address this, we propose a fixed-length hydraulic shearing device for copper busbar processing. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed-length hydraulic shearing device for copper busbar processing, in order to solve the problem mentioned in the background art that existing copper busbars need to be transferred and sheared using a material transfer device after the drawing process. During shearing, the copper busbar is in a conveying state, which easily causes the cut of the copper busbar to be inclined, thus affecting the shearing quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed-length hydraulic shearing device for copper busbar processing, comprising a transmission mounting frame, two guide rails fixedly mounted in the middle of the transmission mounting frame, a follower seat and a mounting plate fixedly mounted between the two guide rails, the follower seat being located directly in front of the mounting plate, a distance measuring head fixedly mounted at both ends of the front end face of the mounting plate, two reflector seats fixedly mounted at the rear end of the follower seat, a shearing mold seat mounted on the inner side of the bottom end of the follower seat, a clamping tooth plate, a displacement monitoring unit and a shearing blade being sequentially mounted on the upper end face of the shearing mold seat from front to back, a first hydraulic cylinder fixedly mounted in the middle of the upper end face of the shearing blade, and a second hydraulic cylinder fixedly mounted at both ends of the upper end face of the clamping tooth plate.

[0006] Preferably, the displacement monitoring unit includes a mounting frame, the inner side of which is provided with a plurality of support springs, and the inner side of the plurality of support springs is slidably connected to a guide frame, and a displacement sensor is fixedly installed on the inner side of the bottom end of the guide frame.

[0007] Preferably, wheel seats are fixedly installed at all four corners of the follower seat, a drive motor is fixedly installed on one side of one of the wheel seats, a guide wheel is rotatably connected to the bottom of the wheel seat, two guide rails are rollingly connected to the bottom of the four guide wheels, the output end of the drive motor is fixedly connected to one of the guide wheels, and the two guide rails are symmetrically installed relative to the follower seat.

[0008] Preferably, a plurality of drive rollers are rotatably connected to the inner side of the transmission mounting frame, and the plurality of drive rollers are arranged linearly from front to back, and a support frame is fixedly installed on the lower end face of the transmission mounting frame.

[0009] Preferably, the two reflector mounts and the ranging head are coaxial, the bottom end of the follower mount is fixedly connected to the shearing mold mount, the lower end face of the displacement sensor passes through the guide frame and is in contact with the upper end face of the shearing mold mount, the mounting frame is connected to the guide frame by multiple support springs, and the follower mount is fixedly connected to the mounting frame.

[0010] Preferably, both the second hydraulic cylinders and the first hydraulic cylinder are fixedly connected to the follower seat, and a copper busbar is provided between the shearing die seat and the clamping tooth plate and the shearing blade, with the copper busbar conveying in the direction from front to back.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses multiple transmission rollers to uniformly transport copper busbars from front to back above the transmission mounting frame. The guide frame, supported by multiple support springs under the support of the mounting frame, drives the displacement sensor to slide and adhere to the upper surface of the copper busbar. Thus, the displacement sensor can monitor the amount of copper busbar transported relative to the shearing die. Two second hydraulic cylinders drive the clamping tooth plate to move downward. Under the support of the shearing die, the clamping tooth plate can clamp the copper busbar. The copper busbar can drive the follower seat to move through the shearing die and the clamping tooth plate. The follower seat maintains stable movement under the guidance of two guide rails through four guide wheels. 2. In this invention, during the process where the shearing die holder, clamping tooth plate, and shearing blade are stationary relative to the copper busbar, the first hydraulic cylinder drives the shearing blade to perform the shearing operation on the copper busbar, effectively improving the shearing quality and avoiding the inclination of the cut when the copper busbar moves relative to the shearing blade. After shearing, the clamping tooth plate is reset, and the drive motor drives the follower seat to move in the opposite direction relative to the copper busbar through one of the guide wheels. The two measuring heads, supported by the mounting plate, monitor the distance between the mounting plate and the follower seat through two reflector seats, and then control the movement speed of the follower seat according to the length of the copper busbar sheared, thereby facilitating the shearing blade to repeatedly perform equidistant shearing on the copper busbar in the conveying state.

[0016] Please see Figures 1 to 4 This utility model provides an embodiment of a fixed-length hydraulic shearing device for copper busbar processing, comprising a transmission mounting frame 2, with multiple transmission rollers 3 rotatably connected to the inner side of the transmission mounting frame 2, the multiple transmission rollers 3 being arranged linearly from front to back, a support frame 1 fixedly mounted on the lower end face of the transmission mounting frame 2, two guide rails 4 fixedly mounted in the middle of the transmission mounting frame 2, a follower seat 7 and a mounting plate 13 fixedly mounted between the two guide rails 4, the follower seat 7 being located directly in front of the mounting plate 13, wheel seats 6 fixedly mounted at each of the four corners of the follower seat 7, a drive motor 8 fixedly mounted on one side of one of the wheel seats 6, a guide wheel 5 rotatably connected to the bottom end of the wheel seat 6, two guide rails 4 being rolledly connected to the bottom ends of the four guide wheels 5, the output end of the drive motor 8 being fixedly connected to one of the guide wheels 5, the two guide rails 4 being symmetrically mounted relative to the follower seat 7, so that the drive motor 8 drives the follower seat 7 to move in the opposite direction relative to the copper busbar through one of the guide wheels 5, facilitating repeated equidistant shearing of the copper busbar.

[0017] Please see Figure 3 and Figure 4The mounting plate 13 has two fixedly mounted distance measuring heads 14 at both ends of its front end face. The follower seat 7 has two fixedly mounted reflector seats 12 at its rear end. The two reflector seats 12 and the distance measuring heads 14 are coaxial. Under the support of the mounting plate 13, the two distance measuring heads 14 monitor the distance between the mounting plate 13 and the follower seat 7 through the two reflector seats 12. Then, the movement speed of the follower seat 7 is controlled accordingly based on the length of the copper busbar shearing.

[0018] Please see Figure 3 and Figure 4 A shearing die base 9 is installed on the inner side of the bottom end of the follower base 7. A clamping tooth plate 16, a displacement monitoring unit, and a shearing blade 15 are installed sequentially from front to back on the upper end face of the shearing die base 9. A first hydraulic cylinder 10 is fixedly installed in the middle of the upper end face of the shearing blade 15. A second hydraulic cylinder 11 is fixedly installed at both ends of the upper end face of the clamping tooth plate 16. The two second hydraulic cylinders 11 and the first hydraulic cylinder 10 are fixedly connected to the follower base 7. A copper busbar is provided between the shearing die base 9, the clamping tooth plate 16, and the shearing blade 15. The copper busbar is conveyed from front to back. Under the support of the shearing die base 9, the clamping tooth plate 16 can clamp the copper busbar. At this time, the copper busbar can drive the follower base 7 to follow through the shearing die base 9 and the clamping tooth plate 16.

[0019] Please see Figure 4 The displacement monitoring unit includes a mounting frame 17. Multiple support springs 18 are provided on the inner side of the mounting frame 17. A guide frame 19 is slidably connected to the inner side of the multiple support springs 18. A displacement sensor 20 is fixedly installed on the inner side of the bottom end of the guide frame 19. The bottom end of the follower seat 7 is fixedly connected to the shearing die seat 9. The lower end face of the displacement sensor 20 passes through the guide frame 19 and is in contact with the upper end face of the shearing die seat 9. The mounting frame 17 and the guide frame 19 are connected by multiple support springs 18. The follower seat 7 is fixedly connected to the mounting frame 17. The displacement sensor 20 can monitor the amount of copper busbar conveyed relative to the shearing die seat 9.

[0020] In summary, after the copper busbar is drawn, it is transferred to multiple transmission rollers 3. The power is turned on, and the copper busbar is conveyed at a constant speed from front to back above the transmission mounting frame through multiple transmission rollers 3. At this time, the copper busbar moves between the shearing die 9, the clamping tooth plate 16, the displacement monitoring unit and the shearing blade 15. The guide frame 19 drives the displacement sensor 20 to slide and fit against the upper surface of the copper busbar through multiple support springs 18 under the support of the mounting frame 17. Thus, the displacement sensor 20 can monitor the conveying amount of the copper busbar relative to the shearing die 9. When the conveying amount of the shearing die 9 meets the shearing length; Two second hydraulic cylinders 11 are activated, causing the two second hydraulic cylinders 11 to drive the clamping tooth plate 16 to move downward under the support of the follower seat 7. Then, under the support of the shearing die seat 9, the clamping tooth plate 16 can clamp the copper busbar. At this time, the copper busbar can drive the follower seat 7 to move through the shearing die seat 9 and the clamping tooth plate 16. The follower seat 7 maintains stable movement under the guidance of the two guide rails 4 through the four guide wheels 5. When the shearing die seat 9, the clamping tooth plate 16 and the shearing blade 15 are stationary relative to the copper busbar, the first hydraulic cylinder 10 is activated, causing the first hydraulic cylinder 10 to drive the shearing blade 15 to perform shearing operation on the copper busbar under the support of the follower seat 7. This effectively improves the shearing quality and avoids the cut tilting when the copper busbar moves relative to the shearing blade 15. After the shearing is completed, the clamping tooth plate 16 is reset. At this time, the drive motor 8 is started, so that the drive motor 8 drives the follower seat 7 to move in the opposite direction relative to the copper busbar through one of the guide wheels 5. The two measuring heads 14, supported by the mounting plate 13, monitor the distance between the mounting plate 13 and the follower seat 7 through the two reflector seats 12. Then, the moving speed of the follower seat 7 is controlled according to the length of the copper busbar shearing, so that the shearing blade 15 can repeatedly shear the copper busbar in the conveying state at equal intervals.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
