摘要： A hydroforming apparatus (10) is capable of deforming relatively large and thick-walled workpieces, yet is relatively small, simple, and inexpensive in construction and operation. The hydroforming apparatus includes an upper platen (20) and a lower platen (30) that are connected together by tie rods (43) extending through respective compression tubes (40, 41). An upper die section (83) is supported on the upper platen (20), while a lower die section (84) is supported on the lower platen (30) for vertical movement relative to the upper die (83) section. The upper and lower die sections (83, 84) have respective recessed areas (83a, 84a) formed therein that define a hydroforming die cavity. When the lower die section (84) is moved to a lowered position, a workpiece (93) can be disposed in the recessed area formed therein. Then, the lower die section (84) and the workpiece (93) are elevated by cylinders (72) such that the workpiece (93) is enclosed within the hydroforming cavity and mechanically deformed by the cooperated upper (83) and lower (84) die sections. A hydroforming support block (90) is then moved between the hydroforming die and the lower platen (30). A cylinder array containing a plurality of pistons (56) is next hydraulically actuated so as to securely clamp the hydroforming die between the cylinder array and the lower platen (30). While the cylinder array is actuated, pressurized fluid is supplied within the workpiece (93), causing it to deform into conformance with the hydroforming die cavity.

摘要： A hydroforming apparatus (10) includes upper and lower platens (20,30) that are connected together by tie rods (43) extending through respective compression tubes (40). An upper die section (64) is carried on the upper platen by a generally C-shaped suspension arm (67), while a lower die section (65) is carried on the lower platen (30). The upper and lower die sections (64,65) have recessed areas (64a,64b) formed therein that define a die cavity. Lift assemblies (70) are provided on the lateral ends of the hydroforming apparatus (10) for selectively elevating the lower die section (30) upwardly into engagement with the upper die section (20). When the lower die section (30) is elevated by the lift assemblies (70), a workpiece (80) is enclosed within the die cavity. A bolster (60) is then moved between the hydroforming die (65) and the lower platen (30). A cylinder array containing a plurality of pistons is next hydraulically actuated so as to securely clamp the hydroforming die between the cylinder array and the lower platen. While the cylinder array is actuated, pressurized fluid is supplied within the workpiece, deforming it into conformance with the die cavity.
