When bending of the sheet metal is required, the control center sends a command to the motor box 2 in the bending machine body 1 to drive the electric actuator 103 to start working. The telescopic end of the push rod 103 then moves, driving the second rotating shaft 105 and the mounting bracket 104 to move upward. At the same time, as the mounting bracket 104 rises, the protective plate 7 rotates via the rotating rod 8, thereby realizing the opening and closing function of the protective plate and providing sufficient space for the placement of the sheet metal. In addition, the telescopic function of the electric push rod 103 allows the opening and closing angle of the protective plate 7 to be flexibly adjusted according to actual needs, enabling the bending machine to adapt to the processing requirements of sheet metal of different sizes and thicknesses, greatly improving its flexibility and versatility. At the same time, the protective plate 7 also effectively prevents the sheet metal from flying out due to improper placement or operational errors, thereby greatly reducing the risk of worker injury and improving the operational safety and convenience of the bending machine body 1.
