Clutch type pressing plate flying shear

The utility model discloses a clutch type pressing plate flying shear which comprises a blade and a driving mechanism. The pressing plate flying shear comprises the driving mechanism, a crank shaft connection rod shearing mechanism, a plate pressing mechanism and a control system. A clutch with a band-type brake in the driving mechanism is connected with a transmission shaft. The transmission shaft is connected with the crank shaft connection rod shearing mechanism to drive the crank shaft connection rod shearing mechanism to do shearing motion up and down. The plate pressing mechanism is fixed on an upper cutter frame of the crank shaft connection rod shearing mechanism. The control system is connected with the driving mechanism to control the clutch in the driving mechanism to do corresponding motion. The clutch type pressing plate flying shear has the advantages of being rapid in shearing speed and shearing in a fixed mode and in a movable mode, and each motion period is less than 0.2 second.
