Abstract: In a method for thickening a plastically deformable hollow body wall of a hollow body, with effective radial support of the unthickened hollow body wall on an outer supporting face of an outer mold and with effective radial support of the hollow body wall on an inner supporting face of an inner supporting body, the hollow body is acted on by a compressive force by two application members at application points by moving the application members towards one another in the axial direction with a compressing movement. The application points on the hollow body are distanced from one another in the axial direction. An expansion space of the outer mold is arranged between the application points.

Abstract: A method for thickening a plastically deformable hollow body wall of a hollow body includes the steps of arranging the hollow body in an outer mold, arranging an inner supporting body inside the hollow body, applying a compressive force to the hollow body wall by means of two application members moving towards one another in an axial direction with a continuous compressing movement, and performing an axial relative movement of the application members performing the continuous compressing movement on the one hand and of the outer mold on the other hand. Due to the compressing movement of the application members, material of the hollow body wall is plasticized and flows into an expansion space of the outer mold, an axial extent of the expansion space increasing due to the axial relative movement of the application members performing the continuous compressing movement and of the outer mold.

Abstract: A forming die for pressure-forming workpieces comprises a die core and a core reinforcement in the form of a reinforcement member made of fibre-reinforced plastics material. The reinforcement member is radially pretensioned against the die core and comprises a plastics matrix and a reinforcing fibre structure which is embedded in the plastics matrix and which extends in the peripheral direction of the die core. A method for producing the forming die includes applying the the fibre-reinforced plastics material to the die core so as to produce a radial pretensioning of the reinforcement member against the die core.

Abstract: A rotary swaging machine comprises a tool unit having a tool space which receives a plurality of shaping swaging tools. The swaging tools are used for processing a workpiece which can be introduced into the tool space. A front cover locking mechanism of the tool unit includes an actuation device and is provided for locking a front cover of the tool unit in a position in which the front cover at least partially covers the tool space at a tool space side. In order to change swaging tools, the front cover can be unlocked and moved into a position in which the front cover releases the tool space for removal or insertion of swaging tools at the tool space side.

Abstract: A tool unit of a rotary swaging machine (1) has a tool space (9) in which there are provided a plurality of shaping swaging tools for processing a workpiece (5) which can be introduced into the tool space (9), and a front cover (13) by means of which the tool space (9) can be at least partially covered at a tool space side (14). The front cover (13), in order to change shaping swaging tools, can be moved into at least one position in which the front cover (13) releases the tool space (9) for removal or insertion of shaping swaging tools at the tool space side (14). Ease of handling when tools are changed is achieved by there being provided a front cover locking mechanism (20) which is provided with an actuation device (26) and by means of which the front cover (13) can be locked in a position in which the front cover (13) at least partially covers the tool space (9) at the tool space side (14).
