| (54) | Apparatus for pressing a metal plate into a desired shape |
| (57) An apparatus for pressing a metal plate into a desired shape. It includes a lower
die (1) having a cavity (2) formed on its upper surface; a rotary die (4) supported
in the cavity rotatably around a rotational axis extending in a longitudinal direction
of the rotary die. The rotary die (4) has a press-shaping section (4a) formed extending
in the longitudinal direction; and an upper die (7) having a counter press-shaping
section (6) formed to engage with the press-shaping section (4a) of the rotary die
with the metal plate sandwiched therebetween at a time of pressing and shaping the
metal plate. The lower die (1) and the rotary die (4) are so shaped that their cross
sections may take an L-shape, and the horizontal and vertical extensions of the lower
die have receiving surfaces (8a,8b) provided thereon to confront the counter abutment
surfaces (11a,11b) of the rotary die. The rotary die (4) can move between a working
position for pressing and shaping the metal plate and a rest position in which the
finished metal plate may be removed readily from the lower die (1). |
