A method of radial incremental forming a component having a component inner mold line (IML) includes providing a mandrel having geometry configured to mate with the IML. The method also includes inserting the mandrel into a tubular workpiece composed of a formable material, to thereby sleeve the workpiece over the mandrel. The method additionally includes mounting the workpiece sleeved over the mandrel onto a drive mechanism configured to rotate the mandrel and having a forming tool configured to shift relative to the workpiece. The method further includes regulating, according to provided toolpath instructions, the drive mechanism to rotate the workpiece sleeved over the mandrel in concert with shifting the forming tool relative to the workpiece to incrementally deform the workpiece therewith over the mandrel and thereby form the component. A tool system having an electronic controller may employ the subject method to radially incrementally form a component.

A forming device which expands a metal pipe material to form a metal pipe having a pipe portion and a flange portion includes first and second dies paired with each other and including pipe forming surfaces for forming the pipe portion and flange forming surfaces for forming the flange portion, a drive unit that drives at least one of the first and second dies, and a controller that controls the drive unit, in which, on at least one of the flange forming surfaces of the first and second dies, a protrusion portion protruding by an amount not to abut against the other flange forming surface when the dies are closed is formed and the controller controls the drive unit to form a thin wall portion at which a thickness of the flange portion becomes partially small at the flange portion by the protrusion portion pressing the flange portion.

A method for producing a component by forming a plate from steel at room temperature having a high formability and reduced crack sensitivity of edges that have been mechanically cut or punched on the plate, includes: cutting the plate from a strip or metal sheet at room temperature; heating edge regions of the plate that underwent strain hardening as a result of the cutting step to a temperature of at least 600° C. for a time period of at most 10 seconds; and forming the plate in one or more steps into a component at room temperature, wherein in the forming step the edge regions heated in the heating step are subjected to cold forming.

Ionic liquid bath plating methods for depositing aluminum-containing layers utilizing shaped consumable aluminum anodes are provided, as are turbomachine components having three dimensionally-tailored, aluminum-containing coatings produced from such aluminum-containing layers. In one embodiment, the ionic liquid bath plating method includes the step or process of obtaining a consumable aluminum anode including a workpiece-facing anode surface substantially conforming with the geometry of the non-planar workpiece surface. The workpiece-facing anode surface and the non-planar workpiece surface are positioned in an adjacent, non-contacting relationship, while the workpiece and the consumable aluminum anode are submerged in an ionic liquid aluminum plating bath. An electrical potential is then applied across the consumable aluminum anode and the workpiece to deposit an aluminum-containing layer onto the non-planar workpiece surface. In certain implementations, additional steps are then performed to convert or incorporate the aluminum-containing layer into a high temperature aluminum-containing coating, such as an aluminide coating.

A method for manufacturing a press-formed product includes a blanking step of blanking from a sheet-shaped material into a shape in which an excess material portion is added to the contour outline of a developed shape of the press-formed product, a first pressing step of folding the excess material portion to form straight sides into an intermediate formed product with a bent flange portion, a second pressing step of performing press forming including bulging in which the bulging portion is provided on the intermediate formed product, and a trimming step of trimming the excess material portion. A blank material includes excess material portion to be folded to form straight sides circumscribed around or spaced apart from a contour outline of a developed shape of the press-formed product, and an intermediate formed product includes excess material portion including a bent flange portion folded to form straight sides.

A method for producing a clamping ring in which pins that protrude in the region of or near a ring contour are formed on the top and bottom surfaces of a flat sheet metal material and after the ring contour is cut out, burrs that are produced during the cutting are removed by a deburring process. Advantages for the machining of the clamping ring are achieved if before a finish cutting by a complete cutting-out of the ring contour that is carried out from the one side of the flat sheet metal material, the ring contour is partially cut out from the other side in the vicinity of or near the pin protruding from this other side.

A method of forming a metal part that includes placing a metal blank in a stamping apparatus having a first die including a plurality of metal gainers and a second die including a plurality of recesses that correspond to the plurality of metal gainers, and compressing the metal blank such that the metal gainers and the corresponding recesses provide the metal blank with regions of localized stretching. Each of the metal gainers and recesses includes a flat surface such that during the compressing of the metal blank to provide the metal blank with the regions of localized stretching, a strain exerted on the metal blank by the metal gainers and recesses is less than a strain exerted on the metal blank by metal gainers and recesses that do not include the flat surface.

An impact forming device and method for local small features on a metal thin-walled curved-surface part. The impact forming device includes impact forming dies, impact loading units and a forming supporting die, wherein the impact forming die is provided with an impact forming part, and the impact forming part is a convex part corresponding to a local small feature; the forming supporting die can support and fix a metal thin-walled curved-surface part without forming local small features, and the forming supporting die is provided with concave parts matched with the impact forming parts; and the impact loading unit includes a guide rail, an explosive ball and a detonating block, under the impact loading of the impact loading units, the impact forming parts can impact the metal thin-walled curved-surface part without forming local small features under the matching action of the concave parts to form the local small features.
