Abstract

PURPOSE: To simultaneously form the end parts and flat parts of a rib-form steel plates through pressing of a subbase at the bottom face of a die and enhance productivity by moving a die slide downward and approaching the die to the inner side with the tapered face thereof.
CONSTITUTION: When the flat part 1c of a worked rib-form steel plate is supplied onto a sub-base 17, a core metal 18 ascends and fits into the inner side of a rib 1a and positions the same. Next, the end part 1b of the rib-form steel plate is inserted into the opposing spacing of a die 11. Thence, a die slide 12 is moved downward by a hydraulic cylinder 19. Then, while the bottom face of the die 11 is pressing the flat part 1c by the force nearly corresponding to the compressive force of a spring 21, its tapered face 12a moves the die 11 to the inner side with its tapered face 11b, and the protruding part 11a of the die 11 holds the end part 1b of the rib 1a and starts molding. At this time, the flat part 1c is pressed by the bottom face of the die 11 by the pulling force of the die slide 12, whereby the flatness is maintained.
