Abstract:
A plate reduction press apparatus comprising dies arranged vertically opposite each other on opposite sides of a transfer line in which a material to be shaped is transferred horizontally, and moving towards and away from the transfer line in synchronism with each other,a plurality of upstream table rollers arranged on the upstream side of the dies on the transfer line in such a manner that the lower surface of the material to be shaped, which is to be inserted between the dies, can be supported substantially horizontally, a downstream table disposed at a height, a first and a second of downstream up and down table rollers arranged on the downstream side of the dies on the transfer line in such a manner that the downstream up and down table rollers can be raised and lowered and can support the lower surface of the material after being shaped and fed out of the dies, the first downstream up and down table roller being disposed at a height in close vicinity of a main press apparatus unit on the downstream side of the transfer line, and extending substantially horizontally along the transfer line in a manner such that the first downstream up and down table roller can be moved up and down, the second downstream up and down table roller being disposed downstream of the first downstream up and down table roller, and is raised and lowered so that the height of an upstream end is disposed identical to the height of the first downstream up and down table roller, and the height of a downstream end is disposed slightly higher than the height of the downstream table, and a plurality of downstream table rollers arranged on the downstream side of the downstream up and down table rollers on the transfer line in such a manner that the lower surface of the material after being shaped and fed out of the dies can be supported substantially horizontally at a height substantially the same as the height of the said upstream table rollers.
