Abstract

PURPOSE: To let corrugations of high pitch accuracy be readily formed by slide approaching both holding parts while applying the load in the plate thickness direction in the intermediate position in the state where the two positions spaced in the lengthwise direction of the horizontally placed plate are held from above and below.
CONSTITUTION: When an upper plate 8 is pushed down, a blank plate is held between chucks 11, 11' and lower slides 15, 15'. When the upper plate is further lowered, punches 21 are raised by the action of perpendicular rods 26 and levers 24 and at the same time the both chucks are slide approached by the action of the slopes of side plates 9. Hence, protruding parts are formed in the blank plate between the side edge parts of both chucks and the punches. At this time, stoppers 17 are protruded and engaged with the side edge parts of the lower slides by means of perpendicular rods 14 and levers 18 and therefore the protrusions are accurately positioned. This method enables the corrugated plate to be formed at high efficiency without applying undue force to the punches.
