Abstract: A lubrication ring (300), for use in a fabrication press (10) having an assembly (20) with a main cavity (160) and a die nib (110) disposed on a surface of the cavity for ironing a workpiece passing through the cavity, includes a groove (360) surrounding a periphery of and opening into the main cavity of the assembly. At least one passage (350) is provided for introducing a fluid into the groove so as to flow within the groove. The fluid is introduced into the groove at a velocity which causes a centrifugal force exceeding the force of gravity to act on the fluid flowing in the groove.

Abstract: A method of die-necking the open end (23) of a can body to form a reduced diameter neck (22) having a smooth profile comprising forming a reduced neck at the open end of the cylindrical sidewall (21) of the can body by engaging the open end of the sidewall with a die having a multi-radius (R1,R2) forming profile, with each successive radius from the entrance to the exit of the die being smaller than the previous radius and with the angle (B,C) through which each successive radius extend being equal to or smaller than the angle of the previous radius. Then a subsequent die-forming stations, forming progressively smaller reduced diameter necks (40,60,84,86,88,25) by a series of dies, all of which preferably have the same multi-radiused forming surface profile which virtually eliminates the undesirable formation of pleats in the final neck configuration.

Abstract: The ram is supported through a hydrostatic type bearing support assembly mounted on a main frame. The support bearings are formed with a unique arrangement of hydrostatic pressure pad slots and hydrodynamic stepped end sections to center the ram with constantly pressurized and flowing oil films supplied through the pressure pad slots. The hydrodynamic bearing sections provide hydrodynamic support at high reciprocating speeds and the pressure pad slots provide hydrostatic support at lower reciprocating speeds that occur at the end of the working and return strokes of the ram. A piston and cylinder arrangement mounted to the bearing housing imparts a deflection force against the ram, between the end bearings and through a center bearing, to counteract gravitational vertical deflection of the unsupported working end of the ram. A cardan type crank drive mechanism for converting rotational input force into straight line reciprocating movement of an output shaft is also disclosed.
