Abstract

PURPOSE:To enable manufacture of large-sized end plates at excellent productivity by pressing material of cylindrical steel using flat, truncated conical and hemispherical punches and a hemispherical, ring-shaped lower die. CONSTITUTION:A cylindrical steel material A having the same weight as that of the object end plate is placed on a hemispherical lower die 1 and pressed by a hemispherical punch 2 to form A1 which has hemispherical lower face and a flat upper face. Then, an end plate A4 having an object shape is formed by pressing changing the punch successively to a truncated conical punch 3 and a hemispherical punch 4 and changing the lower die to a ring-shaped lower die that has a hole 5'. Since a cylindrical steel of small diameter is used as a material instead of a steel plate, a large-sized end plate can be manufactured without being restricted by spacings of supports of a press.
