[0002] Copper busbars, as an important conductive material, are widely used in high and low voltage switchgear, bus ducts and various power transmission systems. The accuracy of their size and shape directly affects the performance and safety of the equipment. Therefore, when cutting copper busbars, they must be accurately positioned through limit devices to avoid material waste or equipment failure due to cutting errors. Effective cutting limit can not only improve production efficiency, but also ensure the overall quality and electrical safety performance of the product.

[0003] At present, the copper busbar shear limit devices on the market generally have certain limitations and shortcomings. Most existing devices are often designed and manufactured for copper busbars of specific specifications and sizes, lacking versatility and flexibility. When copper busbars of different specifications or sizes need to be processed, it is often necessary to replace the corresponding limit components or readjust the equipment parameters, which not only increases the cumbersomeness of the operation, but also significantly increases the time and cost of production preparation. What is more serious is that when faced with copper busbars with complex or irregular shapes, existing devices often find it difficult to provide a stable and reliable limit effect, or even fail to achieve effective limit, which seriously affects the processing accuracy and efficiency. Therefore, there are deficiencies and cannot meet the production and use needs of manufacturers. Therefore, it is necessary to further improve it.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a copper busbar shear limit device is provided, in order to achieve a more practical purpose. Summary of the invention

[0041] See also Figures 7 to 9 An open groove 3721 is provided at one end of the limiting rod 372 away from the limiting plate 373, and the clamping component 38 includes an electromagnet sleeve 381 fixedly assembled in the open groove 3721, and a rotating iron ball 382 is movably installed in the electromagnet sleeve 381, and a clamping member 383 for adaptively fitting the copper bar is fixedly installed on one side of the rotating iron ball 382; the clamping member at the outer end of the limiting rod 372 is tightly fitted with the outer wall of the copper bar, and the clamping member can be adaptively rotated to the position with the largest contact area with the outer surface of the copper bar and the most stable force due to its characteristic of being able to rotate along the obstacle point when subjected to force. Through this arrangement, it can effectively clamp and limit when facing copper bars of different shapes, forming the most stable clamping and limiting structure, effectively ensuring the stability and adaptability of the clamping and limiting.

[0042] The specific usage and function of this embodiment are as follows: Working principle: When in use, first place the copper bar to be sheared properly on the conveyor belt, then the operator starts the system program by operating the control panel 50, and the program immediately controls the conveyor motor 23 to start operating. The conveyor motor 23 generates kinetic energy and drives the conveyor roller 24 to rotate through its output end, thereby driving the conveyor belt 25 to move, realizing the autonomous feeding of the copper bar. Under the guidance of the conveyor belt 25, the copper bar is accurately fed to the shear base 45 of the shearing mechanism 40; When the copper bar reaches the specified position, the electric telescopic device 34 is started through the control of the system program, and the telescopic rod is retracted by the electric telescopic device 34, so that the movable arm 33 is pulled to slide smoothly on the fixed arm 32, and the sliding of the movable arm 33 drives the relative movement of the limiting component 36, so as to clamp and limit the copper bar. In this process, the continuous pushing of the movable arm 33 causes the limiting component 36 to drive the flexible limiting component 37 to be in close contact with the copper bar, and the limiting rod 372 and the elastic supporting rubber ring 374 in the flexible limiting component 37 cooperate with each other, so that the outer end of the limiting rod 372 can be adaptively fitted based on the shape of the copper bar, ensuring that the copper bar can be accurately and stably limited and fixed when clamping and limiting, and through this setting, the flexible limiting component 37 can be adaptively fitted and limited according to different shapes of the copper bar; In addition, while the limiting rod 372 is clamping and limiting the copper bar, the fitting at the outer end of the limiting rod 372 is tightly fitted with the outer wall of the copper bar. Due to the characteristic that the fitting can rotate along the obstacle point when subjected to force, it can adaptively rotate to the position with the largest contact area with the outer surface of the copper bar and the most stable force. This setting enables it to effectively clamp and limit when facing copper bars of different shapes, forming the most stable clamping and limiting structure, effectively ensuring the stability and adaptability of the clamping and limiting. When the limit rod 372 is completely fitted with the copper bar, the system program controls the electromagnet ring 375 and the electromagnet sleeve 381 to be energized. The energized electromagnet ring 375 and the electromagnet sleeve 381 play a role in the magnetic field, generate attraction to the limit rod 372, and the limit rod 372 is electromagnetically adsorbed and locked by the electromagnet ring 375. At the same time, the electromagnet sleeve 381 also magnetically adsorbs and locks the rotating iron ball 382, ​​thereby effectively preventing the rotation of the fitting. This setting greatly reduces the possibility of loosening and displacement of the copper bar due to impact force during the shearing operation, and further improves the shearing limit effect of the copper bar. Finally, when the copper bar is limited, the drive cylinder 43 is started through the system program control, the drive cylinder 43 generates kinetic energy, and pushes the shearing knife holder 441 and the shearing knife 442 downward through the piston rod, and the downward shearing knife 442 performs precise shearing operations on the limited copper bar to achieve the shearing of the copper bar. During this process, the shearing knife holder 441 drives the shearing knife 442 to move downward, and also drives the stabilizing slide sleeve 47 to slide smoothly on the stabilizing slide rod 46, thereby ensuring the stability of the downward movement of the shearing knife 442, improving the shearing accuracy and effect, and further enhancing the shearing effect on the copper bar.
