Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically to a portable lightweight steel bar tying device. Background Technology

[0002] Reinforcing steel is a steel product widely used in infrastructure projects such as buildings, bridges, and roads. It is typically made of high-quality carbon structural steel, possessing good tensile strength and bending resistance, capable of withstanding substantial loads and deformations. The production process of reinforcing steel includes raw material selection, smelting, rolling, and cutting. Reinforcing steel rolling is divided into hot rolling and cold rolling processes. Hot rolling involves heating the steel billet to a high temperature and then plastically deforming it through a series of rollers in a rolling mill, followed by cooling with water or air. Cold rolling, on the other hand, allows the steel billet to be rolled step-by-step through a series of rollers at room temperature. Compared to hot rolling, cold rolling allows for better control over the dimensional accuracy and surface quality of the steel.

[0003] Chinese Patent CN218692578U discloses a threaded rebar rolling device, including a processing plate and a rolling mechanism. Mounting plates are fixedly connected to the front and rear sides of the upper surface of the processing plate. The rolling mechanism includes rollers, the ends of which are rotatably connected to one side of the mounting plate. The outer surface of the rollers is covered with rubber pads and a limiting wheel. A detachable rectangular plate is provided on one side of the mounting plate, one end of which is rotatably connected to the limiting wheel and a positioning wheel. A support rod is fixedly connected to one side of the mounting plate, one end of which is provided with a telescopic connecting rod, and one end of the connecting rod is rotatably connected to the positioning wheel. Two rollers are provided, each positioned on one side of the mounting plate, and the lengths of the two rollers are matched. This technical solution solves the problem in the prior art where threaded rebar is prone to misalignment during processing, affecting processing quality.

[0004] However, the above technical solution has the following shortcomings: the second motor drives the limit wheel to rotate, which can only push the steel bar from one side. In actual use, it is not only difficult to push the steel bar to move, but the steel bar is also prone to deviation when pushing the steel bar to move, which affects the processing quality of the steel bar.
