Flexible roll forming device, blank guide device, blank feeding device, and flexible roll forming system having the same

A material guide device comprising:

• a base plate having a plurality of guide posts mounted thereto;
• a lower roller unit including a lower slide plate coupled to the guide posts to be movable in up/down directions, a lower roller housing mounted to the lower slide plate, and a plurality of lower rollers mounted to the lower roller housing;
• an upper roller unit including an upper slide plate mounted to respective guide posts, an upper roller housing mounted under the upper slide plate, and a plurality of upper rollers mounted to the upper roller housing;
• a drive motor mounted to one side of the lower slide plate such that a rotation shaft of the drive motor is connected to one of lower roller shafts of one of the plurality of lower rollers for forwarding rotation force thereto;
• and
• pressure applying means provided on the upper plate for applying a pressure to a material passing through between respective lower rollers and upper rollers.

A flexible roll forming system comprising:

• a flexible roll forming device including
• bases respectively disposed on opposite sides with respect to a process direction center line in a left/right direction, each having an opening formed in an upper side thereof connected to an inside thereof, and rails configured thereon on opposite sides of the opening in a lateral direction of the process,
• forward/backward moving means having a slide plate provided to be movable along the rails on the base,
• turning means rotatably provided to the slide plate, and
• roll forming means provided on the turning means to include upper and lower forming rolls for subjecting a material fed thereto to flexible roll forming by using the upper and lower forming rolls while varying positions in the lateral direction of processing with the forward/backward moving means, and angles from a process direction with the turning means;
• a material guide device including
• a base plate having a plurality of guide posts mounted thereto,
• a lower roller unit including a lower slide plate coupled to the guide posts to be movable in up/down directions, a lower roller housing mounted to the lower slide plate, and a plurality of lower rollers mounted to the lower roller housing,
• an upper roller unit including an upper slide plate mounted to respective guide posts, an upper roller housing mounted under the upper slide plate, and a plurality of upper rollers mounted to the upper roller housing,
• a drive motor mounted to one side of the lower slide plate such that a rotation shaft of the drive motor is connected to one of lower roller shafts of one of the plurality of lower rollers for forwarding rotation force thereto, and
• pressure applying means provided on the upper plate for applying a pressure to a material passing through between respective lower rollers and upper rollers;
• and
• a material feeding device including
• a conveyor frame having a plurality of conveyor rollers and guide rails mounted along opposite sides thereof respectively, and
• a centering slider unit including a sliding plate to be slidably movable in the process direction along the guide rails, centering rails mounted on the sliding plate in slanted positions, respectively, and centering sliders provided to be movable along the centering rails for holding opposite tips of sides of the blank material fed thereto.
