An apparatus for forging a hollow body has forging tools which are arranged in a centrically symmetrical way about a forging axis, and a forging mandrel. The forging mandrel has a mandrel core and mandrel segments which are distributed over the circumference of the mandrel core, are exchangeably held on the mandrel core, and form forming surfaces for the hollow space of the hollow body.
A description is given of a forging apparatus having forging tools (5) which are arranged centrally symmetrically about a forging axis (2) and of which the tool carriers (4), which are guided radially in a framework (3), are connected to lifting drive mechanisms (7), which each have a connecting rod (8) supported in a pivotable manner, via abutments (9, 10), on a housing (1), on the one hand, and on the tool carrier (4), on the other hand, and having a common drive for the lifting drive mechanisms (7), this drive comprising a torsional-vibration drive (11) for at least one actuator (12), which is mounted such that it can be rotated about the forging axis (2) and is intended for one of the two abutments (9, 10) of the connecting rods (8). In order to ensure advantageous design conditions, it is proposed that the framework (3) forms the actuator (12) of the common drive for the lifting drive mechanisms (7) and that the torsional-vibration drive(11) is provided between the housing (1) and the framework (3), which is mounted in the housing (1) such that it can be rotated about the forging axis (2).
The invention relates to a method for producing wheel axles, in particular for railway carriages, having a hollow axle body (1), which with respect to thickened bearing seats (2) forms shouldered axle stubs (3) for receiving the wheel and has an inner diameter for the axle stubs (3) smaller than a widened inner diameter between the bearing seats (2), wherein the outer form of the axle body (1) is forged. In order to avoid machining, according to the invention, a hollow forging blank (8) having an inner diameter corresponding at least to the widened inner diameter of the axle body (1) is forged, advancing in the axial direction, using a forging mandrel (13) having a mould section (15) for the widened inner diameter of the axle body (1), before the mould section (15) for the widened inner diameter is pulled out from one end of the hollow forging blank (8) and the still unforged section of the forging blank (8) having the smaller inner diameter is forged with the aid of a forging mandrel (13) having a mould section (14) for the smaller inner diameter of the forging blank (8).
An apparatus is for detaching a workpiece from a cutting table. The workpiece is a cutting cut out from a flexible web made of fiber material. A raising device is displaceable relative to the cutting table receiving the web with the cutting and has a run-up surface for the workpiece ascending from the cutting table for progressively lifting the workpiece from the cutting table. A receiving device progressively receives the workpiece after the run-up surface. A lifting device is provided at a distance above the cutting table and includes a receiver which can be adjusted to the length of the boundary section of the cutting facing the raising device and which holds the received boundary section in a transfer position lifted off from the cutting table. The raising device is displaceable between the lifting device and the web resting on the cutting table.
