Abstract: A fixture for machine tools and the like includes a base member and first and second workpiece support units that are movably connected to the base member and define a space therebetween. The fixture includes a drive assembly that is operably connected to the workpiece support units to move the first and second workpiece support units towards and away from one another. The workpiece support units each include a wedge member extending toward the space between the workpiece support units. The wedge members include opposed engagement surfaces that taper towards one another for engaging slots in opposite ends of a workpiece. Each of the workpiece support units also includes a clamp for clamping a workpiece as it engages the wedge members.

Abstract: A die having various features such as spring pockets and mounting provisions for a lifter bar that can be utilized to make a variety of dies. The dies may include pockets or other mounting features that provide for mounting replaceable plates that can be machined for mounting of die forming and cutting steels and other die components. The die shoe may include an array of pockets or blind holes for mounting nitrogen springs or the like for operation of forming steels and the like. One or more openings may be drilled in the replaceable plates above the pockets selected to receive nitrogen springs, with the remaining unused pockets being covered by the replaceable plate. The replaceable plate and pre-formed spring pockets thereby permit the die to be readily adapted for a particular die. The replaceable plates may be removed, and a replacement plate may be installed as needed for a new die.

Abstract: A fixture includes an enlarged plate having slots in an upper surface, and support members are secured to the plate at the slots. The fixture is utilized to machine parts that are initially flame-cut from a large plate/sheet of hot-roll steel. A plurality of notches are flame-cut into the perimeter of the part. The support members engage the flame-cut slots to secure the part to the plate for machining a first side of the part. Precision notches are machined into the part, and precisely-shaped protrusions on the support members are closely received in the precision notches to precisely locate the part for further machining on a second side thereof.

Abstract: This relates to a resealable lid and cup assembly and method for using the same. The resealable lid has an opening through which liquid flows and a valve mechanism for selectively closing the opening. The valve mechanism is provided on the underside of the lid and is biased to the open position by inward deflection of the side wall of the cup.
