    摘要： A latching mechanism (100) for use in a hydraulic press including an upper and lower die (12,14), said mechanism comprising;
       a locking arm (216) pivotally (118) mounted to said press, said arm having a lip (130) for gripping the upper die (14) when the arm is pivoted to its locking position;
       a driver (210) mounted on a vertically reciprocating member of said press wherein said driver causes said airm to pivot to its locked position when said driver is lowered; and
       wherein said driver has an inclined surface (122) which rides against an inclined surface (124) on said arm when said driver is vertically lowered thereby tilting said arm to its locked position.

    摘要： A method for forming a piece of a sheet metal is performed by positioning a consumable body, made of metal, proximate to the piece of the sheet metal. The consumable body is rapidly vaporized, and the gas pressure generated thereby is directed into the piece of the sheet metal. This results in acceleration of the piece of sheet metal, and it is collided into a stationary body at a velocity, generally in excess of 200 m/s. Depending upon the type of stationary body, the piece of sheet metal is deformed into a predetermined shape or is welded onto the stationary body. The vaporization is accomplished by passing a high current of electricity into the consumable body. The effect of the vaporized metal may be augmented by additional components in the consumable body.

    摘要： A process for manufacturing a shaped sandwich panel includes arranging a sandwich panel (66) adjacent a die (74). The sandwich panel (66) includes a core layer (26') arranged between and connected to a first layer (22') and a second layer (24'). The core layer (26') includes a plurality of apertures (38) that extend through the core layer (26') to the first layer (22'). The first layer (22') engages the die (74). Fluid within the apertures is pressurized to a pressure adequate to at least partially form the sandwich panel (66) to a geometry of the die (74).
