    摘要： Apparatus and method for hydroforming a dual wall conduit having a controlled size gap between the walls, a frame having an upper crown and a lower bed defining a hydroforming space therebetween, the bed having a slideway extending from the space to a load-unload-preform position out of the space. A mold assembly on the slideway has a lower platen and an upper platen defining at least two hydroforming cavities, one cavity being an elongated preform and semi-finish cavity, and the other cavity being an elongated finish cavity. Mold shifting means is positioned for shifting the mold assembly on the slideway from the position in the space between the crown and bed, to and from the forward load-unload-preform position. Mold closing and preforming hydraulic cylinders are operably connected to the upper mold platen for closing the upper platen onto the lower platen and creating mechanical preforming on dual wall tubular stock in the preform and semi-finish form cavity. The upper crown has a peripherally retained bladder over the mold assembly for applying a closure clamping force on the mold assembly by the bladder. A first pair of double acting, tube sealing, hydroforming elements are at the ends of the preform, semi-finish cavity, and a second pair of tube sealing hydroforming elements are at the ends of the finish cavity.

    摘要： Apparatus and method for mechanically and hydroform reconfigurating an elongated tubular workpiece in an elongated cavity between upper and lower tool subassemblies each composed of a plurality of independent tool segments movable axially, relative to the cavity axis, together or spaced from each other, and independently movable transversely of the cavity, usually vertically, in sequence, to grip the end portions of the workpiece while its ends are flared with tapered mandrels, and after the workpiece is filled with liquid, offset deform one workpiece portion while the tool segments are spaced apart and with axial infeed of workpiece material, then offset deform another portion with further axial infeed of workpiece material. Hydroforming pressure is then applied to partially expand the workpiece. Then after withdrawing segment spacing stops, forcing the tool segments together, and totally closing the tool, a greater hydroforming pressure is applied in the workpiece to expand it to the specific cavity configuration. After pressure is relaxed and the mandrels retracted, the tool segments are temporarily held together until the finished part is ejected and removed, and then allowed to separate under force of biasing springs.

    摘要： A method of forming a tubular, double wall, air gap, exhaust duct component for an internal combustion engine, the resulting exhaust duct component, and the blank for such, involving providing an inner membrane duct element, with orifices therethrough spaced along its length, providing an outer structural duct element in 360 degree engagement with the inner duct element in the areas where forming and bending operations are to be performed, conducting such forming and bending operations, securing the resulting blank in a hydroforming die cavity, sealing the ends of the inner element to the ends of the outer element, plugging the ends of the inner element, injecting a liquid, preferably water, into the inner duct element and increasing the pressure on the liquid to expand the outer element away from the inner element and ultimately into conformity with the die cavity while the inner element floats in place, in a manner to create an air gap substantially over the full length of the duct component, i.e., except at the ends.

    摘要： The specification discloses extension nipple formation at acute angles on tubular engine exhaust manifold bodies for lap weld attachment of side runners. An articulated or single axis mandrel is inserted axially into the tubular body, each mandrel portion being in an angular body portion. Precut holes in the body are of oval shape. Laterally extensible forming dies are positioned in guide recesses in respective mandrel portions to be aligned with the precut holes and extensible at acute angles to the body and at an angle to each other. Drawing rods are extensible by transfer actuator cylinders into the dies where the rods are interlocked with the dies by rotary actuators. Power forming actuators then shift the rods and dies outwardly to form cylindrical nipples, the forming actuators temporarily overcoming the transfer actuators, and then returning the dies into the mandrel. The rods are then released from the dies and retracted, and the mandrel with dies withdrawn.
