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.

摘要： A method for forming sheet metal articles, such as automotive body panels, having complex curvatures. Opposing, complementary, pre-form and finish-form tools are used in a single press. A sheet of hot blow-formable sheet metal alloy, heated to a forming temperature, is placed between the tools. The pre-forming tool is lowered to a first stage closed position thereby trapping edges of the sheet between binder surfaces of the tools. The sheet is first stretched against the pre-form tool using pressurized gas to form a pre-form that undergoes most of the metal stretching required for the final part shape. Then the finish-form tool is pivotably advanced into a second stage closed position. The pre-form is displaced away from the pre-form tool and hot plastically formed against the opposing finish-form tool with pressurized gas to obtain the final sheet metal part shape. The finish-form tool is then pivotably retracted so as to avoid die lock or part interference conditions.

摘要： An apparatus for hydraulic high-pressure forming of a sheet, the apparatus having a top tool and a bottom tool as well as at least one pressure generating unit arranged between the press ram of a mechanical press and the top tool and uses a pressurized medium from the pressure generating unit as a working fluid for hydraulic preforming of the sheet. Contact faces of the tools directly engage with the sheet surface along the clamping area thereof and act to seal off the forming area that are subjected to the working fluid solely by contact sealing.
