Abstract: A housing for differential mechanism is formed in two pieces using a cold flow-forming process. Each of the housing portions is formed with an internal hemispherical surface, and semi-circular recesses, which when aligned form circular recesses within which a pinion shaft is seated. A subassembly that includes the pinion shaft, pinion gears, side bevel gears, and a thin plastic liner surrounding the subassembly is located within a lower housing portion so that the pinion shaft is seated in the recesses. The upper housing portion is inserted within the upper portion and welded. A ring gear is joined to a housing portion.

Abstract: A press 14 used to impart shape to a workpiece through a tool actuator assembly 62, 63, 64. The press 10 has a crown 16 and a bed 17 between which the workpiece is located. Columns 57, 58, 59, 60 extend between the crown 16 and the bed 17. Each tool actuator assembly 62, 63, 64 is attached to a side of the press and is adjustably mounted between a pair of adjacent press columns.

Abstract: A die assembly (10) for shaping a workpiece (12). The die assembly (10) includes a die shoe (22) within which a channel (24) is provided. A hollow die head (32) may move within the channel. One or more passages are disposed within the die head (32). Within each passage is a locking member (46) which is seatable within a groove (52) defined within a head portion (50) of a shaft (48) which transmits a shaping force to the workpiece (12) or a driven or shaping force within the die assembly (10), thereby allowing the shaft (48) to rotate axially. The die assembly (10) permits the die head (32) and shaft (48) to move in unison during the initial stages of retraction. During later stages of retraction, the die head (32) becomes unlocked from the shaft ( 48).
