Corrugated plate manufacturing apparatus

A corrugated plate manufacturing apparatus for forming a corrugated metal plate product that has a corrugated pattern, which includes alternating ridges and furrows that are continuously and alternately arranged one after another, the corrugated plate manufacturing apparatus comprising:

• a primary die that includes a plurality of primary forming punches, which are stacked one after another in a first direction;
• a secondary die that opposes the primary die in a second direction, which is perpendicular to the first direction, wherein the secondary die clamps a material of the corrugated metal plate product between the primary die and the secondary die to deform the material of the corrugated metal plate product and thereby to form the corrugated pattern, which includes the alternating ridges and furrows continuously and alternately arranged one after another in the first direction in the material of the corrugated metal plate product, at a time of forming the corrugated metal plate product;
• a plurality of primary sliders that are arranged one after another in the first direction such that each of the plurality of primary sliders corresponds to each corresponding one of the plurality of primary forming punches, wherein the plurality of primary sliders is movable in a third direction, which intersects the first direction and the second direction;
• and
• a primary slider drive portion that sequentially drives the plurality of primary sliders toward one side in the third direction, wherein:
• each of the plurality of primary forming punches includes a plurality of primary pressable portions that are arranged one after another in the third direction and are pressable by a corresponding one of the plurality of primary sliders;
• and
• when the plurality of primary sliders is sequentially moved toward the one side in the third direction, each corresponding one of the plurality of primary sliders presses the plurality of primary pressable portions of each corresponding one of the plurality of primary forming punches to press the primary forming punch against the secondary die.
