|20150217354||PRESS MACHINE AND PRESSING METHOD - A press machine includes a lower die having a step portion for forming a bent portion on a side surface, a pad portion supported by a spring and disposed adjacent to the lower die in the horizontal direction, being movable upward and downward, an upper die disposed opposing the pad portion in the vertical direction, and a regulation portion. When the upper die moves downward and presses a steel plate between the upper die and the pad portion to form a bent portion in an edge portion of the steel plate, the regulation portion moves together with the upper die and regulates the motion of the edge portion of the steel plate protruding from the lower die in the horizontal direction, thereby preventing a wrinkle from forming in the edge portion of the steel plate.||08-06-2015|
|20140360675||AUTOMATIC ATTACHING APPARATUS OF FOAMED SEAL MEMBER - An automatic attaching apparatus of a foamed seal member includes an attaching hand handling a foamed seal member, a preset machine in which the foamed seal member is preset, a removing machine removing a release paper, and a robot moving the attaching hand. The attaching hand picks up the foamed seal member from the preset machine, presses the foamed seal member from which the release paper is removed against an attaching surface of a work using a pressing roller in a state where the foamed seal member is floated by an air floating device, and sends out the foamed seal member to attach the foamed seal member to the attaching surface of the work.||12-11-2014|
|20140239672||METHOD OF MANUFACTURING VEHICLE BODY SIDE STRUCTURE AND VEHICLE BODY SIDE STRUCTURE - First to third steel members are cut to form predetermined planar shapes using press machines and form an upper member, a reinforcement member and a lower member. The carbon content of the third steel member is set lower than the carbon content of the first and second steel members. The upper member, the reinforcement member and the lower member are then assembled. The reinforcement member is superposed on the upper member. The upper member and the lower member are partially superposed. The superposed portions of the upper member and the reinforcement member and the superposed portions of the upper member and the lower member are then respectively joined by spot welding to form a blank member. The spot welded blank member is then heated to a temperature of a transformation point or higher, and the blank member is hot press formed by one press machine.||08-28-2014|
|20090266801||METHOD OF LASER WELDING METAL PLATED PLATES - The invention provides a method of laser welding zinc plated steel plates which surely realizes excellent welding without a melting defect such as blowholes. By irradiating a line on a superposed portion of a lower plate and an upper plate with a first laser beam having a high energy density and a small irradiation region by moving the first laser beam therealong, steel plate portions in the small irradiation region are melted and zinc on the superposed surfaces around the small irradiation region including in the small irradiation region is evaporated and allowed to escape outside. Then, after the irradiation with the first laser beam, the same line is irradiated with a second laser beam having a lower energy density than the first laser beam and a larger irradiation region than the first laser beam by moving the second laser beam therealong to melt steel plate portions in the larger irradiation region, thereby completing weldbonding.||10-29-2009|
