Description

Technical Field

[0001] This utility model relates to the field of metal wire drawing technology, and in particular to a tension compensation mechanism for a steel bar wire drawing device. Background Technology

[0002] Tension compensation in rebar drawing devices refers to a mechanism that automatically adjusts and compensates for the tension on the steel wire during the rebar drawing process to maintain stable tension. During the drawing process, various factors such as changes in drum speed, uneven wire diameter, and fluctuations in material properties can cause changes in the tension on the steel wire. Tension compensation devices typically monitor the tension of the steel wire in real time through sensors and then automatically adjust relevant components based on the monitoring results. Stable tension allows the rebar to deform uniformly during the drawing process, reducing defects such as uneven wire thickness and surface scratches caused by tension fluctuations, improving the mechanical properties and dimensional accuracy of the rebar, and enabling it to better meet the usage requirements of industries such as construction.

[0003] CN213103806U discloses a wire drawing tension adjustment device. Its structure includes a base plate, a fixed pulley, and a tension wheel. A base is provided on one side of the base plate. The base is fixedly connected to the bottom end of a support column. The top end of the support column is rotatably connected to the fixed pulley. A tension wheel is provided on the other side of the base plate, and the tension wheel is connected to the base plate via an adjustment mechanism. The adjustment mechanism includes a fixed shaft, a rotating plate, and a connecting column. The bottom end of the fixed shaft is fixedly connected to the base plate, and the fixed shaft is rotatably connected to one end of the rotating plate. The other end of the rotating plate is fixedly set to the connecting column. A positioning plate is integrally connected to the bottom of the connecting column, and a positioning hole is provided on the positioning plate. A threaded hole is provided on the base plate. The upper end of the connecting column is rotatably connected to the tension wheel. The fixed pulley and the tension wheel are provided with a winding track for winding metal wire from top to bottom. This device can quickly adjust the tension of the metal wire and ensure tension stability. However, its tension wheel is manually adjusted and fixed, which is inconvenient to operate and cannot guarantee stability. Poor dynamic stability makes it difficult to accurately control the adjustment precision. Therefore, a tension compensation mechanism for rebar wire drawing devices is needed. Utility Model Content

[0024] Please see Figure 1-4 This utility model provides a technical solution: a tension compensation mechanism for a rebar wire drawing device, including a workbench 1 and a dynamic adjustment compensation mechanism. The dynamic adjustment compensation mechanism includes a device base 2, a mounting plate 3, an adjustment plate 16, a motor 18, a threaded rod 19, and a sliding rod 20. The device base 2 is fixedly connected to the bottom of the workbench 1, the mounting plate 3 is fixedly connected to the bottom of the device base 2, the adjustment plate 16 is slidably connected to the top of the device base 2, the motor 18 is fixedly connected to the surface of the device base 2, the threaded rod 19 is rotatably connected to the surface of the device base 2, the output end of the motor 18 passes through the device base 2 and is fixedly connected to the threaded rod 19, the threaded rod 19 is rotatably connected to the surface of the mounting plate 3, the sliding rod 20 is fixedly connected to the opposite surfaces of the device base 2 and the mounting plate 3, the adjustment plate 16 is threadedly sleeved on the outer surface of the threaded rod 19, and the adjustment plate 16 is slidably sleeved on the outer surface of the sliding rod 20.

[0025] Furthermore, the surface of the workbench 1 is provided with an arc-shaped groove 10, and a limit rod 15 is slidably connected inside the arc-shaped groove 10. The limit rod 15 is slidably connected inside the adjusting plate 16. The surface of the adjusting plate 16 is provided with a limit groove 17 that matches the limit rod 15. A moving rod 13 is fixedly connected to the top of the limit rod 15. A tension wheel 14 is rotatably connected to the top of the moving rod 13. A rotating shaft 11 is fixedly connected to the top of the workbench 1. A rotating plate 12 is rotatably sleeved on the outer surface of the rotating shaft 11. The rotating plate 12 is rotatably sleeved on the outer surface of the moving rod 13. A fixed seat 4 is fixedly connected to the top of the workbench 1.

[0026] Furthermore, during use, the steel wire is wound around the fixed pulley 9 and the tension wheel 14. During the output process of the wire drawing machine, the motor 18 is controlled to drive the threaded rod 19 to rotate according to the tension of the tension sensor, so that the adjusting plate 16 slides on the top of the device base 2. During the parallel movement of the adjusting plate 16, the limiting rod 15 is driven to move along the arc of the arc groove 10, thereby changing the distance and angle between the fixed pulley 9 and the tension wheel 14 and adjusting the steel wire tension. During the wire drawing process, the lifting plate 6 can be driven to rise and fall by the hydraulic cylinder 5, thereby driving the rotating rod 8 and the fixed pulley 9 to rise and fall, which makes it easier to wind up the steel wire.

[0027] Furthermore, by driving the threaded rod with a motor to linearly displace the adjusting plate, precise dynamic adjustment of the tension wheel position is achieved. This, combined with the arc-shaped groove guide mechanism, ensures the smoothness of the tension compensation process. The hydraulic lifting mechanism and the adjustable fixed pulley group work together to maintain constant wire tension in real time during the wire drawing process. The linkage design of the rotating plate and the limit rod allows the tension wheel to adaptively adjust along a predetermined trajectory, effectively eliminating the lag and instability of traditional manual adjustment. This mechanism realizes closed-loop control of tension during the wire drawing process, solving the problem of insufficient precision in manual adjustment. At the same time, the optimized layout of the mechanical structure improves the reliability of equipment operation and the adjustment response speed.
