Abstract
Abstract Pressurized viscous fluid, pumped by annular pistons, flows in contact with one surface of a blank inwardly from the periphery thereof, thereby to force the opposite surface of the blank against a low friction surface, thereby to pressurize the blank and exert viscous drag force on the surface of the blank to extrude the peripheral portion of the blank inwardly, in cooperation with a ram perpendicularly engaging the central portion of the blank, to deep draw the blank through a die opening. In a modification, a heating element is provided in contact with the flow of viscous fluid opposite the surface of the blank contacted by the viscous fluid to raise the efficiency of the operation. In another modification, by proper staging, the average pressure in the viscous fluid can be made to increase in the overall direction of flow of the viscous fluid. The viscous fluid can be applied to inwardly extrude the blank uniformly or non-uniformly. In yet another modification, pressurized viscous fluid, pumped by annular pistons, flows in contact with both faces of a blank inwardly from the periphery thereof, thereby to pressurize the blank and exert viscous drag force on both surfaces of the blank to extrude the peripheral portion of the blank inwardly.
