Abstract:
1. A magnetic pulse forming device for a roll forming system, comprising: forward and rearward guide rolling means disposed on a base and guiding movement of a forming beam; a guiding means comprising guiding rails disposed on the base between the forward and the rearward guide rolling means and guide frames movably disposed on the guiding rails; a magnetic forming means comprising an upper plate connecting the guide frames corresponding an upper surface of the forming beam, a coil housing assembled to the upper plate and a coil disposed within the coil housing and electrically connected to a pulse generator to generate a magnetic pulse by input current; a movement detector detecting movement of the forming beam; a synchronizing means comprising a lead screw disposed along the base, a synchronizing motor connected to the lead screw to rotate the lead screw, and a screw housing engaged with the lead screw and moving the guide frames with the forming beam in the process direction by rotation of the lead screw; and a forming mold that is disposed on the screw housing through an ascending/descending cylinder corresponding to the magnetic forming means and that supports a lower surface of the forming beam and the forming mold to which a forming surface for forming a predetermined shape to the forming beam by the electromagnetic force generated from the coil is formed.
