Abstract
PURPOSE: To easily form a striplike metal plate with small pressing force and prolong the life of dies by beforehand forming slight projections and flat parts corresponding to the peak parts of waves to the surface of said plate.
CONSTITUTION: Prior to formation of a wave 2, a concave thread 8 extending in the width direction is formed by pressing the part of a striplike metal plate 5 of width slightly narrower than the peak part width l1 corresponding to the back surface of the peak face of the wave 2, whereby flat peak part width l1 is obtained. Thence, with this striplike metal plate 5 having undergone pretreatment working is grasped at the parts on both outer sides thereof by means of gripping means 7aW7d from the vertical directions, that is, arrow G, H directions, with the concave thread 8 at the center, and while the metal plate 5 is being moved in the arrow J, K directions, a punch 3 is moved upward and is pressed to a die 4, whereby the plate is formed to a waveform. These cause the concave thread 8 to make action of leading the plate to the predetermined waveform bending direction, thus the pressing force of the punch 3 is decreased and the abrasion and failure of the dies are decreased.
