Follow-up shearing mechanism of reinforcement bar straightening machine

The invention relates to the technical field of reinforcement bar straightening machines, in particular to a follow-up shearing mechanism of a reinforcement bar straightening machine. The follow-up shearing mechanism of the reinforcement bar straightening machine comprises a machine frame, a first swing arm, a slide rod, a movable cutter, a second swing arm and a follow-up cutter, wherein the first swing arm is hinged to the machine frame; the upper portion of the slide rod is connected with the first swing arm; the movable cutter is arranged at the lower end of the slide rod; the first swing arm is driven by a first drive device to swing; the upper portion of the second swing arm is hinged to the machine frame; a sleeve is arranged on the lower portion of the second swing arm; the slide rod is located inside the sleeve; the follow-up cutter is arranged on the wall, located below the slide rod, of the sleeve; and the second swing arm is driven by a second drive device to swing. When the follow-up shearing mechanism of the reinforcement bar straightening machine works, the movable cutter downwards moves along the sleeve with the slide rod under the driving of the first swing arm to cut off reinforcement bars fed into the follow-up cutter, at the same time, the slide rod swings in the feeding direction of the reinforcement bars under the driving of the second swing arm, the effect that the reinforcement bars operate at the stable speed without stop in the shearing process is ensured, the production efficiency is improved, and mechanical damage to the reinforcement bars is also avoided.
