ABSTRACT:
A multi-step press system includes a press that consists of a press frame, a table provided on the press frame and a ram provided above the table for making movement in a Z-axis direction. The table has a standby station into which workpieces are loaded one by one and a plurality of press-forming stations in which the workpieces are sequentially press-formed. The system further includes a press die set consisting of a lower die attached to the table and an upper die attached to the ram. The lower die and the upper die are adapted to simultaneously press-form the workpieces placed in the press-forming stations. On one side of the press, there is provided a destacker for periodically loading the workpieces into the standby station. A transfer feeder is provided between the table and the ram for simultaneously picking up and transferring the workpieces.
