    摘要： A blankholder having a central opening for applying pressure against the flange of a blank being drawn through a die in a draw press. The blankholder is divided into individual segments defined by its inner and outer peripheries, at least one continuous divisional line intermediate the inner and outer peripheries, and radii extending outwardly from the central axis. Each individual segment is provided with a different power source so that each segment can provide a force to the blank flange independent of the force being applied by any other segment.

    摘要： The present invention involves a detachable half shaft assembly of a vehicle wheel end and has a shaft bell and a disc rotor. The detachable half shaft comprises a preloaded bearing assembly and a detachable body receiving the preloaded bearing assembly. The preloaded bearing assembly has an inner surface formed through inboard and outboard ends thereof. The detachable body has an inboard interface at an inboard end and an outboard interface at an outboard end. The inboard interface is configured for connecting to the shaft bell and the outboard is configured or connecting to the disc rotor. The detachable body has a bearing receiving portion defined by the stepped boss and a roll formed base. The bearing receiving portion radially receives the inner surface of the preloaded bearing assembly. The stepped boss and the roll formed base engages the bearing assembly and the inboard and outboard ends to maintain the preload thereon when the detachable half shaft assembly is detached from the shaft bell or the disc rotor.

    摘要： A method of superplastically forming a part from a blank of material. The blank is placed between opposed die structures and heated to a superplastic forming temperature. Positive fluid pressure is supplied at an increasing rate against a front surface of a blank to stretch the same into a cavity of one of the dies to begin formation of the part. A positive fluid pressure is also applied against the back surface of the blank, and acoustical energy emitted by the material of blank resulting from the occurrence of cavitation in the material is sensed. The sensing of acoustical energy is employed to control one or more of the above parameters until the formation of the cavities substantially reduces or ceases altogether.

    摘要： A method of forming an object having a relatively deep cavity from a superplastic metallic blank wherein a preform having a bottom portion and sides sloping upwardly and outwardly therefrom is first superplastically formed in a female mold. The preform is then attached to a male mold with the bottom portion of the preform in a snug fit with a top portion of the male mold which has outside dimensions equal to the cavity in the object and thereafter the preform is superplastically forced against the male mold to form the desired object.

    摘要： A method of forming a metal sheet workpiece into a three-dimensional object by subjecting the workpiece to a stretch forming process along at least two strain paths having slopes of opposite sign. The strain paths define a point on a forming limit curve that is shifted substantially from a forming limit curve generated by linear strain paths. The shift in forming limit curves allows a substantially higher strain state to be reached in the workpiece in comparison to a strain state achievable using linear strain paths to attain the same strain state in flowing metal into a die cavity. The three-dimensional object is formed by flowing workpiece metal into a die cavity in a manner that controls the position and magnitude of forces restraining the periphery of the workpiece such that metal flow into the cavity takes place along the strain paths having the slopes of opposite sign.
