Abstract: A second press 10 irons a plate-like steel plate W. This second press 10 comprises a base block 22 for supporting the lower surface of the steel plate W, a rod 11 disposed on the upper surface of the steel plate W, an upper die 30 including a guide rail 24, a first cam 25 and a second cam 34 and a lifting mechanism 40 for moving the rod 11 along the surface of the steel plate W. The base block 22 regulates the movement of the rod 11 in a thickness direction of the steel plate W by contacting the upper surface of the rod 11 over the movement range of the ironing member in the surface direction of the steel plate W.

Abstract: A die set for press-forming a blank of thin metallic sheet. The die set has a punch and a blank holder. The blank holder has a first bead for restraining an edge of the blank with a constant force. The first bead is disposed further to an inside than a second bead for restraining the edge of the blank with a force that varies during pressing of the blank.

Abstract: An aqueous deformation-detecting brightener composition that can easily detect deformation such as unevenness on the surface of a car body by forming a liquid thin film having low foaming property and excellent glossiness is provided by dissolving a glycol ether compound expressed by the following formula (I) and a surfactant in water R1—O—(AO)m—R2  (I) where “R1” represents an alkyl group having 1 to 9 carbon atoms, an alkenyl group having 1 to 9 carbon atoms, an alkylphenyl group having 1 to 9 carbon atoms, or a functional group expressed by the following general formula (II), “A” represents an alkylene group having 2 to 4 carbon atoms, “m” represents an average adduct molar number of alkylene oxide, a number of 1 to 20, in which the same alkylene oxide may be added alone, or a mixture of two or more types of alkylene oxide may be added, and “R2” represents an alkyl group having 1 to 9 carbon atoms, an alkenyl group having 1 to 9

Abstract: After outer panels have been assembled on a vehicle frame, they are coated with an aqueous lustering agent P, and then irradiated with a light beam L. Light reflected by the outer panels is processed to produce a degree and range of distortion thereof. Based on the produced degree and range of distortion, it is determined whether the outer panels suffer a surface distortion or not. The determined result is displayed on a display monitor. According to the displayed image, the outer panels are repaired and thereafter coated with a paint.
