The invention discloses a
metal wire rod precision alignment
cutting device and a method. The device comprises a double-layer
machine frame. A front end guiding tank, a revolving alignment tank, a traction mechanism, a back end guiding tank, a
cutting mechanism and a machinery
sizing mechanism are arranged on the top portion of the double-layer
machine frame. The revolving alignment tank comprises a revolving alignment straight tank support seat, an alignment guiding tank, a plurality of alignment modules and a protection cover. The traction mechanism comprises a traction mechanism support seat, a
servo motor, a driving friction wheel and a driven friction wheel. The
cutting mechanism comprises a cutting wheel support frame, an air cylinder, a cutting wheel motor and a slice-shaped cutting wheel. The machinery
sizing mechanism comprises a horizontal scale plate, a
pressure sensor, an
infrared transmitting sensor and an
infrared receiving sensor. The method includes the steps that the
metal wire rod enters the revolving alignment tank through a front end guiding rank. The
metal wire rod is alignmented, tracted,
cut and prepared and enters the next working circulation. The metal wire rod precision alignment cutting device and the method is high in automatic degree. The shape of the
cut metal
line segment and the size precision are high. The cutting opening is smooth, free of
deckle edge and free of splitting off. The metal wire rod precision alignment cutting device and the method are strong in practicality.
