Abstract: A method and apparatus for heating and/or pressing sealant of an insulating glass unit. The apparatus may include an oven and a press. The oven includes a detector that detects an optical property of the insulating glass unit. The detected optical property is used to regulate the amount of energy applied to the insulating glass unit to adjust the amount of energy applied to the sealant. The press may include a displacement transducer that detects a pre-pressed thickness of the insulating glass unit. The measured pre-pressed thickness is used to automatically select a press thickness from a set of pressed IGU thicknesses.

In one embodiment, a ballizing unit having a distal end removably coupled to a ballizing member moves the ballizing member from a first position within the bore hole to a second position. A metrology unit having a distal end removably coupled to the ballizing member moves the ballizing member from the second position back to the first position. A sensor detects a force exerted on the ballizing member by the workpiece at a third position, which is located between the first and second positions.

Abstract: A method of manufacturing a catalytic converter is described where the catalytic converter is comprised of an outer tube member having a monolith substrate internally compressed therein with a wrapped mat material surrounding the monolith substrate and intermediate the outer tube. One or more monolith members can be applied within the outer tube and heat shields may also be applied internal to the outer tube and adjacent to the monolith substrate. The assembly of the catalytic converter includes measuring the sequence of compression of the mat material to the monolith substrate in order to understand the possible force characteristics which can be applied during the assembly thereof. The mat material is therefore compressed within the outer tube by way of compression jaws, by compression rollers, and/or by spinning. The compression of the mat material can be in single or multiple steps.

At least two fluid valves are connected to respective connecting rods and manifolded together with a hydraulic chamber disposed in or adjacent the connecting rods. An electrically adjustable proportional valve is connected to the fluid valves which operate to vary the pressure at which the fluid valves open to unload the slide.

A variable relief mechanism automatically relieves pressure within the hydraulic chambers dependent on an operating state of the press.

Abstract: The invention provides a method of bending a workpiece to a predetermined bending angle, in which, in a first step, the workpiece is bent to a somewhat greater bending angle and then released. Thereafter, the amount of resilient back motion occurring after the first bending operation is measured. The adjustable die bottom is readjusted such that a bending angle would result in the next bending operation which corresponds to the desired final bending angle minus the amount of resilient back motion. After the second bending operation, the workpiece is released and the legs thereof will resiliently move back to enclose the final predetermined bending angle.

Abstract: A pair of press tools, such as punches, are mounted on a tool support for axial reciprocation between extended and retracted positions with respect to the support. The tool support may be defined by a press slide, bed or component part of a tooling package mountable thereon and is provided with a hydraulic fluid receiving cylinder for each of the tools. Each tool is interconnected with a piston received in the corresponding cylinder and the cylinders are in flow communication with one another. Accordingly, if one of the tools engages a workpiece before the other during operation of the press, the one tool is displaced in the direction of retraction causing the other tool to be displaced in the direction of extension until both tools engage the workpiece, thus to avoid eccentric loading of the press slide and frame.

Abstract: An improved adapter cushion is used in a press with a die assembly having a plurality of projecting die pins. The adapter cushion includes a one-piece cylinder block in which a plurality of cylinder chambers are formed. Cylinder sleeves or liners are telescopically disposed in the cylinder chambers and are connected with the one-piece cylinder block by threaded connections. Replaceable tubular guide bushings are disposed in the end portions of the sleeves to guide relative movement between the die pins and the cylinder block. In order to provide a yieldable support for the die pins, pistons are urged toward axially outer ends of the sleeves under the influence of fluid pressure. During operation of a press, the die pins work against the fluid pressure acting on the pistons. In order to facilitate utilization of the adapter cushion with different types of dies, a cylinder sleeve can be readily removed and a cylinder plugged without disassembling the adapter cushion.

Abstract: The forging press has a horizontal drive shaft on which is carried an eccentric body linked to a vertical force-transmitting block whose lower surface lies at an angle to the horizontal and flushly engages the top of a horizontally reciprocal wedge whose bottom surface lies on the hammer. Interfitting ridges and grooves interconnect the wedge, the force-transmission block, and the hammer so that the hammer hangs from the wedge and the wedge from the force-transmission block. A spindle threaded into the wedge is rotatable to establish its horizontal position, and, therefore, to set the relative position of the force-transmission block in the hammer. At its other end this spindle is provided with a piston reciprocal in a horizontally extending hydraulic chamber which is maintained under a predetermined pressure. The threshold at which the wedge may slip to the side and protect the hammer from overloading is established by the pressure in this hydraulic cylinder.
