PURPOSE: A rotary cold former is provided to improve the production speed by producing two products through one compression cycle by one rotation of a crank shaft. CONSTITUTION: A rotary cold former includes a rotating nit(R1) and a punch unit(P11). In the rotating unit, punch dies, which are changed according to the shape and the size of products, are inserted in die holders and the die holders are radially, symmetrically arranged on a die block(R2) around the center of rotation. The rotating unit is rotated in a specific direction at a predetermined angle per a predetermined period by a ratchet driving device. The punch unit includes a punch block, a push disk(R3) which moves back and forth along a slide shaft, and a push pin rod whose one end is connected to a punch holder and the other end comes into contact with the leading end of the push disk so that the push pin rod is moved to separate a processed product in a punch of the punch holder when the push disk is moved forward. Two wire rods are supplied from a complex reel unit through a complex straightening roller unit, continuously transferred through a plurality of rotating rollers, and cut at one time by a cutting unit, so that both ends of the two wire rods are formed with the punch dies of the rotating unit and the punch of the punch unit. |
