Abstract: A cap tip assembly for spot welding is disclosed. The cap tip assembly for spot welding is configured to spot-weld a first base material in which a flange is formed and a second base material overlapping the flange in a vertical direction. The cap tip assembly for spot welding includes a tip body provided in a shape of a rectangular block in which a round-shaped welding section is formed on a front side of a top surface, and a collet member coupled to the tip body to guide a conductive tape to the welding section.

Abstract: A heat spreader and waveguide (HSWG) unit of the present invention includes a main body having a ceiling portion and a wall wherein the ceiling portion and the wall are provided with waveguides, and one or more heat spreader modules in a space inside the main body, wherein at least one waveguide among a waveguide extending downward from one lower side of the heat spreader module and an intermediate waveguide extending downward in a curtain manner is further included, and each of the ceiling portion and the wall is formed in a unit length so that a plurality of units is combined to form a paint drying furnace.

Abstract: A roll forming device for forming a variable thickness plate is disclosed.

Abstract: A roll forming device for forming a variable thickness plate is disclosed.

Abstract: A flexible roll forming device is provided. The roll forming device includes bases respectively disposed on opposite sides with respect to a process direction center line in a left/right direction of which rails are configured thereon along a lateral direction of the process direction center line, and upper and lower forming rolls configured to vary both positions in the lateral direction of processing, and angles from the process direction.

Abstract: A welding device for a stretch bender is disclosed. The welding device for the stretch bender may include: an operating unit adapted to move forward toward or rearward from a bending die for shaping a shaped beam and mounted in front of the bending die; and a welding unit mounted at the operating unit and welding flange portions of the shaped beam that is completely formed by the bending die so as to prevent the flange portions from being overlapped with each other when extracting the shaped beam, the welding unit being movable forward or rearward against the operating unit.

Abstract: 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 of which rails are configured thereon along 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 an upper forming roll and a lower forming roll inclined with respect to the upper forming roll 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.

Abstract: A irradiation facility of radiant heat comprises one or more radiation generators (10); and a waveguide (20) connecting between the radiation generator (10) and a target object (30) to increase irradiation distance thereof such that electromagnetic waves in a radiation region provided from at least one of the radiation generators (10) are irradiated onto the target object (30). The irradiation facility of radiant heat is characterized of a substantially increased radiation distance of electromagnetic wave in a radiation region and unlimited yet variable radiation direction and radiation intensity to be able to focus the radiation only on the target object, so that energy efficiency and product quality of the target object are improved while power consumption is reduced.

Abstract: Disclosed is a far infrared drying apparatus, including: at least one far infrared drying unit, which is heated by an electric heating element and converts heat energy into far infrared rays, namely, electromagnetic wave energy: a support name for supporting the at least one far infrared driving unit; a moving device for moving the support frame; and a waveguide for guiding the far infrared rays over a long distance onto an object to be dried.
