Abstract (en)
[origin: WO2015140280A1] The invention relates to a shaping tool (3) for a workpiece (2), in particular for plastically shaping a pipe end, comprising a clamping device (17) which comprises multiple clamping segments (18) and comprising a compressing head (9) which has a depression (10) on one side for forming a workpiece contour to be shaped and a securing means (11) on the opposite side for connecting to a shaping piston (5) of a device (1) for deforming the workpiece (2). The aim of the invention is to allow a reduction of the assembly complexity when changing tools while ensuring a high degree of assembly security. This is achieved in that the compressing head (9) and the clamping device (17) are structurally connected in a circumferential manner in a single tool unit (3) so as to allow an axial movement relative to each other. In the device (1) according to the invention, such a shaping device (3), in the form of the tool unit (3), is arranged on a common longitudinal axis (X-X) together with a shaping assembly (5, 6, 7, 8, 9) which is actuated by the pressure of a fluid (F) and together with a clamping assembly (15, 16, 17, 19) which is actuated by the pressure of the fluid, and the shaping device can be connected to a cylinder unit (4).
