An electrohydraulic forming chamber to form a workpiece. The chamber includes a discharge frame that has an inner wall which delimits a discharge space provided to hold a volume of fluid, a female mold having a forming space which includes an impression configured to be complementary to the shape of the workpiece after deformation, and an electrohydraulic discharge system. The workpiece is placed between the discharge space and the forming space before the electrohydraulic discharge system is activated. Upon activation of the electrohydraulic discharge system, the workpiece is catapulted against the impression in the forming space and is deformed accordingly. All or part of the inner wall is provided with a non-metal coating.

A method for shaping a blank comprising a metal includes a step of loading the blank onto a first die, a step of bringing the first die and a second die together, a step of forming a seal around the blank, and a step of injecting a pressurized molten salt into a space in the blank to supply a hydraulic pressure to the blank.

An electro-hydraulic forming machine (1) for the plastic deformation of a projectile part (P13) of the wall (P1) of a workpiece (P) to be formed, preferably a cylindrical tubular workpiece, via a forming fluid (F), includes a tool (4) for applying the forming fluid on the inner face (P11) of the projectile part (P13), the application tool (4) including:a chamber (44) intended to contain the forming fluid (F), cooperating with elements (3) for generating a shock wave in the forming fluid (F) intended to be contained in the chamber (44), andat least one downstream port (42), intended to open opposite the projectile part (P13) of the wall (P1) to be deformed and in fluid communication with the chamber (44), in order to allow the passage of the forming fluid and for propagating the generated shock wave towards the footprint (22) of a target support (2).

A spherical decoupler conduit for connecting misaligned components, and a method for making the same, where the spherical decoupler includes an inlet connection with a first spherical portion; an outer slider with a second spherical portion for pivotably mating with the first spherical portion and a tubular portion; an inner slider having a tubular portion in a telescoping relationship with the tubular portion of the outer slider and a third spherical portion; and an outlet connection with a fourth spherical portion for pivotably mating with the third spherical portion.

A cylinder holder for a hydroforming device has a substantially cuboid cylinder holder body with a hydraulic cylinder seat to which a hydraulic cylinder can be fixed. The hydraulic cylinder is configured to supply a hydroforming fluid to a workpiece to be shaped. The cylinder holder further includes a base plate to which the cylinder holder body is fixed at a predetermined angle with an anti-rotation lock unit.

A system and method of manufacturing a metal vessel may include providing a preform being formed of work hardened aluminum. The preform may have an open portion, a closed portion, and body portion. A multiple segment mold may be closed around the preform. The multiple segment mold may include at least one projecting portion operative to partially deform the preform while closing the mold. The preform may be blow molded by causing a step-like change in pressure within the preform to cause the preform to take a shape defined by the mold when the mold is in the closed position. The molded preform may be removed from the mold.

A component forming tool for forming a component from a blank includes a die forming shell for forming the component from the blank. A first shell portion of the die forming shell is disposed at a first set of support elements and a second shell portion is disposed at a second set of support elements. The tool includes at least one induction heating coil for induction heating of a workpiece disposed within a cavity formed by the first and second shell portions. The first set of support elements may be configured to detachably engage with respective base support elements of the component forming tool, with the first set of support elements keyed to engage the base support elements to limit lateral movement of the first shell portion at the base support elements. The first set of support elements may include at least two layers of different materials.
