摘要： A drive rod composed of segments joined together to form a single length for use in a mechanical press. The individual drive rod segments may be separated for ease of assembly into the mechanical press or for servicing the mechanical press. In addition, a split locating collar is used for removably attaching the drive rod to the upper slide of a mechanical press. Drive rod length and slide shutheight may be changed by utilizing spacer elements.

摘要： A plurality of hydrostatic bearing pads are each integrally formed in a respective pin or journal member being used within a mechanical press machine. The hydrostatic bearing pads are supplied with pressurized fluid sufficient to create a combined hydrostatic and hydrodynamic effect between the opposed bearing surfaces of the pin and an associated bushing. The hydrostatic bearing pads are used in conjunction with rotational and oscillating bearings in which relatively little rotation, oscillation, or slow rotational speeds exist or where it is desired to minimize the effects of hydrodynamic action which creates bearing “lift off” on journal bearings. These types of bearings are particularly associated with crankshaft and connection journal bearings, connection pins, and pivot pins used by a rocker-type coupling assembly that couples a weight assembly to the press machine piston or slide assembly or drive assembly.

摘要： The invention includes a press having two slides disposed in opposed relationship to each other with a single crankshaft connected to each slide whereby rotation of the crankshaft causes each slide to move toward and away from the other slide. A drive mechanism is utilized to rotate the crankshaft. The drive mechanism is located under the two slides to provide protection against oil leaks. Dynamic balancers are utilized to substantially balance press inertia forces during operation, to where over 90 percent of vertical press inertia forces are balanced. By balancing such press inertial, the press may be stopped within one crankshaft revolution.

摘要： A shutheight adjustment assembly of a mechanical press including an adjustment nut rotatably connected to an adjustment screw. Hydrostatic bearing pads are provided below the adjustment nut to reduce frictional forces associated with nut rotation and to provide a squeeze film thickness to withstand large press loadings. A hydraulic chamber supplied with pressurized fluid is positioned above the adjustment nut and produces a preload force on the hydrostatic bearing pads. Hydrostatic bearing pads are also arranged radially outward of the adjustment nut to radially center the nut during operation. A hydraulic chamber between the adjustment nut and screw may be furnished to resist bolster rebound during press operations.
