| 20120125898 | LASER WELDING DEVICE FOR ROLL FORMING SYSTEM AND CONTROL METHOD THEREOF - A roll forming system which roll-forms a shaped beam by a roll forming unit including a plurality of roll formers is disclosed. A laser welding device for the roll forming system may include: front and rear guide means disposed apart from each other at the rear of the roll forming unit, and guiding movement of the shaped beam; laser welding means mounted above and between the front and rear guide means, reciprocatedly rotating a mirror by controlling a mirror motor so as to irradiate a laser beam to a welding position of the shaped beam, and thereby forming a welding bead having a predetermined welding pattern; forming speed detecting means detecting a forming speed of the shaped beam and transmitting a signal corresponding thereto to a controller; a camera disposed at the rear of the laser welding means, photographing a welding portion of the shaped beam, and transmitting an image signal corresponding thereto to the controller. | 05-24-2012 |
| 20120125065 | ROLL FORMING SYSTEM AND ROLL FORMING METHOD - A roll forming system and a roll forming method are disclosed. The roll forming system according to an exemplary embodiment of the present invention includes a bending unit provided with synchronizing means moving a synchronizing table in keeping pace with a forming speed of a shaped beam along a process line, clamping means clamping both sides of the shaped beam, position conversion means converting a position of the shaped beam between a cutting position and a bending position, cutting means cutting one side of the shaped beam by a cutting wheel, and a bending means stretch-bending the shaped beam to have a predetermined curvature. | 05-24-2012 |
| 20110285152 | BUMPER BEAM ASSEMBLY FOR VEHICLE - A bumper beam assembly for a vehicle may include a bumper beam having a horizontal support plate, front and rear vertical support plates attached to the horizontal support plate, wherein the rear vertical support plate includes an insertion hole, a partition formed along the horizontal support plate between the front and rear vertical support plates, and a stay, an end portion of which may be inserted into the insertion hole. | 11-24-2011 |
| 20110155325 | BENDING DEVICE - The present invention relates to a bending device of which a beam is inserted between laminated moldings formed by slidably layering a plurality of molding plates, and the bending device of which deformation of the laminated moldings may simultaneously realize bending of up and down directions and side directions of a curved portion of a beam, and thus the bending device may realize a 3-dimensional bending process at once. | 06-30-2011 |
| 20110139753 | LASER WELDING METHOD FOR STEEL SHEET - The present invention provides a laser welding method for steel sheets. The laser welding method includes irradiating a low heat input laser beam to a weld zone with a uniform welding pattern of a zigzag shape, with a constant pitch, and with a constant welding speed, so that autogenous welding may be achieved without a feed wire, such that cost of material may be reduced and joinability and performance may be improved. | 06-16-2011 |
| 20090165520 | ROLL-FORMING SYSTEM AND METHOD THEREOF - The present invention relates to a roll-forming system and a method thereof that enables both ends of a panel to be formed attractively by roll-forming the panel after cutting grooves are formed at both ends of the panel by using a blanking press. | 07-02-2009 |
| 20090134131 | LASER WELDING METHOD FOR GALVANIZED STEEL SHEETS - The present invention relates to a laser welding method for galvanized steel sheets where galvanized steel sheets are lap-welded by using a laser beam of a keyhole welding zone in a state in which a gap for exhausting zinc fumes is formed by embossing a plurality of protrusions along a welding line on one galvanized steel sheet among the galvanized steel sheets by using a laser beam of a conducting welding region. | 05-28-2009 |
