A shaping method for a double pipe includes: bending the double pipe with a specified curvature to form a bent portion in the double pipe; and arranging the bent portion on a first shaping die having a first shaping surface at a position biased inward or outward in a curvature radius direction of the bent portion relative to the first shaping surface, wherein the first shaping surface is configured to shape a first outer surface of both outer surfaces of the bent portion that are located on both sides of a plane including a central axis of the bent portion, and pressing the bent portion arranged on the first shaping die by a second shaping die having a second shaping surface configured to shape a second outer surface of the both outer surfaces of the bent portion.

A method for producing a flywheel includes producing a damping plate part by permanently connecting at least a first metallic plate element provided for the flywheel to at least one further material layer to form a sandwich component. According to the method, the first plate element is connected by a joining process to at least a second, parallel plate layer, so that they lie on one another to form a disc-shaped structural unit. According to the method, at least two sheet metal layers from different materials and/or at least two sheet metal layers having different material strengths are connected with each other. This enables a large variance for the production of flywheels. In this way, it is possible, for example, to produce a flywheel having a plurality of superimposed plates adapted to the respective load situation in a defined flexibility.

A punching tool intended to make holes in a part made of a sheet metal or a multi-layer assembly of sheet metals, for example a part for the body of a vehicle. The punching tool includes a punch holder holding a one-piece cutting punch and a punch die arranged in front of the punch holder, the punch holder being designed to move the punch toward the die from a rest position to a work position in which the cutting punch cuts out a hole in the part placed between the punch holder and the die. The cutting punch is removably housed in a cavity formed in the punch holder so that, when the punch holder withdraws from the work position to the rest position, the cutting punch separates from the punch holder and remains in the hole pierced in the part.

A manufacturing assembly for manufacturing a metal part comprises a flattening module having a trolley and at least one pressing roller. The flattening module is movable along a hemming of the metal part. The flattening module comprises at least one pressing actuator that is arranged to move the at least one pressing roller in a determined pressing direction relative to the trolley and to place the pressure roller bearing against the free surface such that the at least one pressing roller exerts pressure on the free surface in said determined pressing direction. The pressure increases auto-adaptively with an altitude of the free surface in a direction opposite the determined pressing direction.

Provided is a method of manufacturing a molded product that can reduce problems on a reinforcing plate during pressing. In one aspect of the present disclosure, the method of manufacturing a molded product includes welding a first metal plate overlaid with a second metal plate to the second metal plate; and pressing the first metal plate and the second metal plate together. In the pressing, a base surface and a wall surface are formed on the first metal plate; the wall surface is disposed to cross the base surface. In the welding, a first welding is performed on a reinforcing portion of the second metal plate that is overlaid on an area of the first metal plate that is formed into the wall surface; and subsequently, a second welding is performed in a direction crossing a direction of the first welding.

A manufacturing method is provided during which a plurality of first apertures are formed in a first plate to provide an apertured first plate. A plurality of second apertures are formed in a second plate to provide an apertured second plate. The apertured first plate and the apertured second plate are bonded to a base sheet to form a structure. The base sheet is bent to form a bend in the structure between the apertured first plate and the apertured second plate.

A method of forming a stamped part includes forming a tailor welded blank by friction stir welding (FSW) a first blank to a second blank, removing a FSW start spot and a FSW stop spot from the tailor welded blank using a machining process such that a finished tailor welded blank is formed and stamping the finished tailor welded blank into the stamped part such that a weld formed by FSW the first blank to the second blank is plastically deformed. The first blank and the second blank can be aluminum alloy blanks and a predetermined amount of material is machined from the FSW start spot and the FSW stop spot, the predetermined amount of material being equal to or greater than a thickness of the first blank and the second blank.

A method and a system are disclosed for making an article of manufacture from a blank defining an internal opening. A stack of blanks are aligned and the internal openings of the blanks in the stack of blanks are machined by a rotary cutting tool to a finished dimension. The blanks are clamped together before machining in a numerically controlled machine tool. The blanks are subsequently formed individually in a sheet metal forming operation in which the inner perimeter of the internal openings is expanded as the blank is formed.

A method for producing a multi-layer sliding bearing 1, includes the method steps: —providing a carrier body; —providing a bearing body; —applying the bearing body to the carrier body, wherein a carrier body connecting surface is turned towards a bearing body connecting surface; —deforming a bearing body by applying a magnetic force to the bearing body of using a magnetic force generator, wherein the bearing body is pressed on, by the magnetic force generator, to the carrier body and forms a force-fit and/or positive locking and/or materially bonded connection therewith.

A method of fabricating a conduit comprises steps of attaching a first tubular-outboard-ply-end of a tubular outboard ply to a first inner collar portion of a first collar with a second weld and attaching a second tubular-outboard-ply end of the tubular outboard ply to a second inner collar portion of a second collar with a fourth weld. The method also comprises steps of inserting a tubular inboard ply into the tubular outboard ply, threadably interconnecting the first inner collar portion and a first outer collar portion of the first collar, and threadably interconnecting the second inner collar portion and a second outer collar portion of the second collar. The method further comprises steps of attaching a corrugated inboard ply to the first outer collar portion with a first weld and attaching a corrugated inboard ply to the second outer collar portion with a third weld.
