    Abstract: A pneumatic metal forming press which employs at least one pneumatic drive unit which has an expansion chamber defined by a flexible diaphragm acting on a support mechanism and a shock absorber underlying the support mechanism to absorb the impact thereof following the release of a working tool such as a punch after penetration of a work piece during a working stroke. The drive unit may incorporate a plurality of diaphragm chambers arranged one above the other and connected in parallel to a source of high pressure air. The drive unit may also incorporate a pressure multiplier having a fluid chamber pressurized in response to movement of the diaphragm of a drive mechanism and an output drive shaft driven in response to pressure thereto by the fluid in the multiplier chamber. The drive mechanism may also incorporate a secondary drive mechanism operable to locate the working tool closely adjacent a work piece prior to commencement of the working stroke so that although the press may have a short working stroke, it has the ability to open and close over a substantial operating stroke.

    Abstract: A pressure actuator is provided having a stationary plate and a floating plate for holding an element under compression and a base plate separated from said floating plate by a flexible conduit which defines an inner chamber intermediate said floating and base plates. The conduit is comprised of at least one solid member or track, usually two, which defines an enclosure or ring. Depending on the number of tracks one or two elastomeric bands are employed. The edges of the elastomeric band(s) fit into grooves in the tracks to form a continuous conduit, which has a port for pressurizing. With the continuous conduit intermediate the floating and base plates, a significant portion of the surface of the elastomeric sheet or sheets is in contact with the plates. When a work product is introduced between the stationary and floating plates, the conduit is pressurized with a fluid, defining an hermetically sealed chamber which is also pressurized, at a pressure lower than the pressure in the conduit, to provide a uniform work force against the work product. The pressure actuator finds particular use in pressure applications which require high, uniform force to be applied to the work. When the element is to be released, the pressure in the chamber and conduit is released, lowering the element out of engagement with the upper restraining plate.
