Abstract
PURPOSE: To readily form a strip-form metal plate by small pressing force and prolong the life of dies by simultaneously applying pressing force to said plate in the direction at a right angle to the pressing force and form the both sides of corrugations.
CONSTITUTION: Multiple concave streaks 6a, 6b are formed in the portions corresponding to the bent parts of the top and bottom of the waves 2 of a strip-form metal plate 5 being the work. The strip-form metal plate 5 having been subjected to this treatment is gripped at the outside adjoining portions of the two concave streaks 6b in the position away mutually by a development width l2 by gripping jigs 7a thru 7d from their top and bottom directions, i.e., arrow G, H directions and while the strip-form metal plate 5 thus being held gripped is being moved parallel to the plate plane and in the directions mutually going toward the inner side, i.e., arrow J, K directions, a punch 3 is moved upward to be pushed and pressed to a die 4, whereby the plate is formed to waveform. This makes the pressure force of the punch 3 less than before and eventually reduces the wear and failure of the punch 3 and die 4.
