MAGNETIC PULSE FORMING DEVICE FOR ROLL FORMING SYSTEM AND CONTROL METHOD FOR THE SAME
First Claim
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.

13. A control method for a magnetic pulse forming device for a roll forming system, the control method comprising:
-
detecting rotation speed of a rotating roller according to movement of a forming beam from an encoder and a return signal from a return switch; calculating moving speed of the forming beam according to the rotation speed of the rotating roller; determining whether a current section of the forming beam is a forming section of the forming beam; raising a forming mold by operation of an ascending/descending cylinder, and simultaneously operating a synchronizing motor forward for moving a magnetic forming means with the forming mold synchronized with moving speed of the forming beam if the current section of the forming beam is the forming section of the forming beam; controlling a pulse generator of the magnetic forming means to form and discharge a magnetic pulse to the forming beam using the magnetic pulse and the forming mold; detecting the return signal from the return switch; and operating the ascending/descending cylinder to lower the forming mold and simultaneously controlling the synchronizing motor rearward for moving the magnetic forming means with the forming mold to the original position if the return signal is detected. - View Dependent Claims (14, 15, 16, 17, 18)
