This invention discloses a metal sheet edge-flying shear device with a flat cutting surface function, belonging to the field of shearing equipment technology. It includes a body, roller, drum, rotating cylinder, cylindrical part, drive rod, connecting part, shear blades, and locking unit; a telescopic unit is used to move the drive rod outwards from the drum when the locking unit restricts the rotation of the rotating cylinder, thereby bringing the two shear blades closer together. In use, the rotating cylinder is restricted from rotating by the locking unit, and the telescopic unit drives the two shear blades to move closer together, enabling them to shear the metal sheet. During the shearing process, the rotating cylinder stops rotating, while the drum rotates, allowing the shear blades to maintain a parallel state for a longer period. During this parallel state, the telescopic unit drives the shear blades to move closer together, ensuring the shear blades shear the metal sheet and preventing poor cut quality due to excessively fast shearing speed.

The present application belongs to the field of flying shear equipment, and discloses a flying shear post double-head active steel-patting device system and method. The system comprises a flying shear and a steel-patting device. The steel-patting device is arranged on the steel tapping side of the flying shear and comprises a driving mechanism and two symmetrically arranged rotary arms. One end of each rotary arm is hinged to a mounting seat through a rotating shaft, and the other end of each rotary arm is provided with a steel-patting surface. The driving mechanism drives the two rotary arms to rotate synchronously. The steel-patting device cooperates with the shearing action of the flying shear. When the flying shear is shearing, the steel-patting surface of the rotary arm moves downward to exert a downward force on the billet head, so that the billet head moves downward along a preset trajectory and deviates from the steel passage, thereby avoiding the billet head from being brought into the guide groove, ensuring the shearing safety, and ensuring the stable production of the rolling line. The length of the shearing section process equipment is effectively reduced, the investment is reduced, and the production is increased.
