Technical Field

[0001] The utility model belongs to the field of straightening devices, and in particular relates to a hot-rolled steel bar straightening device which is easy to use. Background Art

[0002] Hot-rolled ribbed steel bars, commonly known as threaded steel bars, are a commonly used construction accessory in the field of construction. The utility model patent with the patent authorization announcement number CN218656572U discloses a hot-rolled ribbed steel bar straightening device, including a machine tool, a fixed plate fixedly connected to the machine tool, an open groove is provided inside the fixed plate, a moving block is slidably connected in the open groove, a second fixed shaft is fixedly connected to the moving block, an extrusion wheel is fixedly connected to the second fixed shaft, a connecting plate is fixedly connected in the open groove, a threaded rod is installed in the connecting plate through a bearing, the threaded rod is connected to the moving block through a thread, and a motor is fixedly connected to the fixed plate. This scheme can support and place the surface-bent hot-rolled ribbed steel bars through the setting of the support wheel. Under the cooperation of the motor, threaded rod, moving block and other structures, the extrusion wheel can be pushed down to extrude the hot-rolled ribbed steel bars to complete the straightening process of the hot-rolled ribbed steel bars.

[0003] In the above-mentioned prior art, during the use of the straightening device, the steel bar can be supported by the support wheel, which is inconvenient to position the steel bar. During straightening, the steel bar may be offset by force, which will affect the straightening work. In the straightening process, the steel bar is pressed down by the extrusion wheel to achieve straightening. When it is necessary to straighten the steel bar at different positions, the relative position of the steel bar and the extrusion wheel needs to be changed, which makes the straightening work inconvenient. Therefore, improvement is needed. Summary of the invention
