The traditional flying shears comprise crank-type flying shears, rotary flying shears or crank-rotary combined flying shears and the like, and the common characteristics of the crank-rotary combined flying shears are that the shearing surface is perpendicular to the travelling direction of the rod and the wire.
Flying shears are typically mounted on a shear channel that is juxtaposed with a rolling channel, with the advancing rod wire being switched between the two channels by a switch: when the flying shears complete the shearing treatment on the rod and wire, the switcher immediately swings to introduce the rod and wire into the rolling channel for rolling; when the rod and wire are rolled, the switcher swings immediately to introduce the rod and wire into the shearing channel for shearing treatment. Therefore, the response time of the switcher directly influences whether the whole steel bar and wire production line can normally run: if the switch is not timely swung, the running rod and wire can impact the flying shears to be accumulated or broken (mainly after the end cutting treatment), thereby causing serious production accidents and huge property loss.
