    摘要： Apparatus and method for forming a peripheral skirt on a workpiece of metal or other ductile material with reduced pleating of its peripheral edge. The concentric mating male and female dies of the prior art are provided, and in addition at least one drawbar concentric with, outside of, and generally beside the male die guides the outer periphery of the workpiece as the dies are urged together, preventing the outer margin of the workpiece from being folded under and propagating pleats. The drawbars also assist in clamping the outer margin of the workpiece between the dies when the central portion of the workpiece is to be expanded by the application of fluid forming pressure.

    摘要： A multiple groove pulley is formed from a cup-shaped blank by an apparatus and method in which axially displaceable segmental shaping rings are positioned at axially predetermined positions along the wall of the blank. Fluid pressure communicated to the interior of the blank expands the wall of the blank into contact with the shaping rings and at least one of the shaping rings is independently movable in an axial direction while the blank is compressed for simultaneous formation of the grooves. A sleeve member is movable axially over at least one of the shaping rings to resist radial movement of the segments while at the same time permitting full compression of the blank.

    摘要： The specification and drawings disclose a method and apparatus for forming dish-shaped metal elements through the use of a combined fluid pressure and sheet tensioning process. The disclosed method is particularly intended for forming dish-shaped sheet metal elements having a length substantially greater than their width and includes applying a longitudinal tension to the sheet while permitting the lateral edges to move toward one another substantially unconstrained while the fluid pressure acts to bow the sheet. The disclosed apparatus includes a flexible frame of generally eliptical shape which clamps to the edge of the sheet. The frame is arranged so that as the sheet bows outwardly, the lateral sides of the frame are pulled inwardly driving the ends of the frame apart.

    摘要： The present invention provides a metal forming system, comprising a platform and a gantry means, in which the platform is provided with a plurality of lower mold bases bearing sheet metals, while the gantry means is provided with at least one upper mold base and a toggle unit. The gantry means is performing lateral displacement on the platform, so as to be displaced to a location above the lower mold base which is predetermined to operate. The toggle unit is for adjusting the longitudinal position of the upper mold base so as to change the distance between the upper mold base and the lower mold base, resulting in determining whether a mold-closing state or a mold-opening state. A metal forming operation is performed on the sheet metal between the upper mold base and the lower mold base so as to manufacture a metal formed part when the mold-closing state.
