A method for production of a metallic material from a semifinished metallic billet, the semifinished metallic billet including a nanocrystalline microstructure and/or an ultrafine-grained microstructure, the method including the steps of (1) subjecting the semifinished metallic billet to a rotary incremental forming process to form an intermediate wrought metallic billet, and (2) subjecting the intermediate wrought metallic billet to a high rate forming process to form a metallic product.

The invention relates to crimping pliers (1). The crimping pliers comprise a spring element (7) which is located in the force flow between hand levers (3, 5) and dies (12). The spring element (7) builds a force-displacement-compensation element (8) which provides the option to be able to crimp workpieces with different cross-sectional areas with the crimping pliers (1). According to the invention, the spring element (7) which builds the force-displacement-compensation element (8) is built in the region of the pliers head (4) of the crimping pliers (1). Preferably, the spring element (7) is a spring in the shape of an arc of a circle or a spiral spring (44) which extends in circumferential direction around the die axis (13).

A radial compression mechanism includes a constraining structure with a cut-out defined by a plurality of bearing surfaces. A plurality of die are carried by the constraining structure and arranged in a circular pattern about a central axis. Each die has a base side positioned in parallel juxtaposition to a corresponding bearing surface and each die is constrained to move reciprocally and linearly along the corresponding bearing surface. Working surfaces of the plurality of die cooperate to form a cavity that is movable between an open position and a closed position. A driving mechanism is coupled to at least one of the plurality of die to drive all of the die in unison between the open position and the closed position.

The inventions relates to crimping pliers with two hand levers (3, 5) and two actuation elements (9, 10) located in the region of a pliers head (4). The actuation elements (9, 10) actuates dies (12) between which a workpiece can be crimped. A toggle lever drive (33) with two toggle levers (34, 35) which build a toggle lever angle (36) acts between the hand levers (3, 5) and the actuation elements (9, 10). One toggle lever (34) is built by a roller (23) which is pivotably mounted to the hand lever (5). The roller (23) rolls along a curved track (24) fixed at the other hand lever (3). A forced locking unit (48) is built with a toothed latching lever (28) which is supported for being rotated relatively to the roller (23). A lever part (30) of the toothed latching lever (28) is coupled by a sliding guide to the hand lever (3), whereas the other lever part (29) of the toothed latching lever (28) forms a toothing (31) for latching of the forced locking unit (48).

A method of manufacturing an aerosol generation system heater element is described. The aerosol generation system heater element comprising a seamless hollow tube, and the method comprises deforming a wall of a hollow tube to form the seamless hollow tube, the seamless hollow tube having a deformed wall, wherein the deformed wall of the seamless hollow tube is thinner than the wall of the hollow tube.

A device and method for continuously producing an at least partly hollow shaft having a varying inner diameter includes forging tools that are arranged centrally symmetrically about a forging axis and are driven radially, a clamping chuck for holding an at least partly hollow cylindrical blank, and a counter-holder for axially supporting the blank. The counter-holder has a base and a counter-holder mandrel arranged on the base and extending axially into a central cavity in the blank. The mandrel is formed of at least two parts, wherein a first part of the counter-holder mandrel constitutes an inner part and a second part of the counter-holder mandrel constitutes an outer part surrounding the inner part. At least the outer part can be moved axially relative to the inner part.
