A method of manufacturing a nut integrated with a bracket forms the nut formed integrally with the bracket or a slab base nut by using a plate material supplied between a punch and a die. The slab base nut includes a base plate and a boss extending from the base plate and including female-threads. The base plate and the boss are integrated into a single piece without welding trace.

Nut integrated with bracket and method of manufacturing the same

A nut integrated with a bracket and a method of manufacturing the same is provided. The method includes a pre-drawing operation that forms a reference aperture and a processing cross section in the plate material supplied between the punch and the die, forming a beading portion and piercing a center of the beading portion. A forging operation forms a pipe portion having a tube shape and processes an exterior circumferential surface of the pipe portion. A precision forging process adjusts dimensions of the pipe portion formed in the tube shape, forms a protruding end that extends on a tip surface of the pipe portion and compresses the pipe portion to remove residual burrs on a surface. A post-processing operation cuts the processing cross section to a final product shape, and forms a threaded tap on an interior circumferential surface of the pipe portion.

A mounting unit is provided that improves compatibility to be applied to various parts of a vehicle body which is coupled with a chassis by manufacturing the mounting unit to include a bracket and hardware. The mounting unit includes a bracket that has a first panel and a second panel, which are respectively bent several times, are combined with each other to form an empty portion to be surrounded by the first panel and the second panel and fixed to a vehicle body. Additionally, the mounting unit includes a hardware that is disposed in the empty portion to be fixed by being combined with the first panel and the second panel and adapted to form a thread for engaging a fastening mechanism.

Mounting unit

A multi-forming method, wherein after a material which is heated to a warm-deformation condition in a mold is deformed to a maximum deformation depth through plastic deformation, and the deformed material which is heated to a super plasticity temperature is blow-formed by blowing gas to a final product shape, a product having a deep forming depth and complicated shape can be produced.

Multi-forming method

A manufacturing method for a bumper beam of a vehicle may include pipe making, producing a circular pipe by pipe molding a steel plate having a predetermined thickness between first and second molding rolls, heating the circular pipe to a set temperature in a heating furnace, pressurizing and molding the circular pipe heated in the heating furnace and having flexibility, while inserting the circular pipe between an upper mold and a lower mold to form a molding beam, and thereafter, rapidly cooling the molding beam to form the molding beam into a high-strength molding beam, and curvature-molding the high-strength molding beam at a predetermined curvature through a curvature molding machine.

Manufacturing method for bumper beam of vehicle

A rivet screw drill for fastening at least two panels, the rivet screw drill includes a head portion mounted to a fastening tool, a fastening portion integrally formed with the head portion and of which a screw thread is formed thereto and a perforating portion integrally formed with the fastening portion and pressurizing and penetrating the panels by rotation according to operation of the fastening tool, wherein a mounting protrusion, connected to the fastening tool, is protruded from the head portion and a plurality of support ends are formed to the mounting protrusion.

Bolt

A mounting bolt for a sub-frame is disclosed. A mounting bolt for a sub-frame that is used to engage a sub-frame to a front side member of a vehicle according to one or a plurality of exemplary embodiments of the present invention may include a bolt body that is inserted into a penetration hole of a mounting bracket fixed on the front side member and is joined to the mounting bracket through a first flange that is formed at an upper end circumference thereof, a support body at which a second flange is formed at a lower end circumference to have a hollow space and is disposed on the bolt body, and a joining plate that is interposed between the first flange and the second flange and is welded with a first join protrusion that is formed on an upper surface of the first flange and a second join protrusion that is formed on a lower surface of the second flange by electrical resistance.

Mounting bolt for sub-frame

A roller hemming apparatus is disclosed. A roller hemming apparatus for hemming an outer panel with respect to an inner panel according to an exemplary embodiment of the present invention may include a tool body mounted at a front end of an arm of a robot, a pre-hemming roller mounted to a front side of a mounting block, which is disposed at a lower portion of the tool body, through a first mounting bracket, a main hemming roller mounted to a rear side of the mounting block through a second mounting bracket, and at least one heater mounted at a lateral side of the mounting block and configured to heat a flange portion of the outer panel.

Roller hemming apparatus

A mounting bolt for a sub-frame is disclosed. A mounting bolt for a sub-frame that is configured to a sub-frame to a front side member of a vehicle according to one or a plurality of exemplary embodiments of the present invention may include a bolt body that is inserted into a through-hole of a mounting bracket that is fixed to the front side member and joined to the mounting bracket through a head portion, and a support body that has a cylindrical shape, is friction-welded to a center of an upper surface of a head portion of the bolt body along one line, and of which an upper end is joined to the front side member.

The present invention relates to a joining method, and more specifically relates to a method for joining different kinds of plates that joins at least two plate members of which materials thereof are different from each other through laser welding. For this, a method for joining different kinds of plates according to an exemplary embodiment of the present invention may include disposing a first plate and a second plate, materials of which are different from each other, such that they are overlapped with each other, and joining the first plate and the second plate by irradiating a laser beam at a predetermined inclination angle and in a regular pattern onto the overlapped portion of the two plates.

Laser welding method for welding dissimilar metal plates

Disclosed is 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 cyclinder having a slide plate provided to be movable along the rails on the base; turning reducer rotatably provided to the slide plate; and upper and lower forming rolls provided on the turning cylinder 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 cylinder, and angles from a process direction with the turning reducer.

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