AI Technical Summary
The existing steel bar cutting device can only cut the steel bars separately, which is inefficient. Since the steel bars are large and long, they require workers to drag, resulting in high labor intensity.
A device including a support plate, a back frame, an electric telescopic rod, a cutting knife, a side strut, a placement table and a moving structure is designed. The rebar is clamped by the placement table and the movable plate, and the motor is driven by a rotating rod and a cylindrical rod. The automatic movement and cutting of multiple steel bars increases cutting efficiency.
Efficient cutting of multiple steel bars is achieved at the same time, reducing workers' labor force and improving the efficiency and safety of steel bar cutting.
