摘要: The invention relates to a device for forming an end area of a workpiece (2), especially for cold press-forming an end area of a pipe, comprising two force transmitting elements (7, 9) which are guided in a common housing (3). The device is characterised in that a first pressure chamber (26) is located between the two force transmission elements (7, 9) and in that a second pressure chamber (28) is allocated to the second force transmission element (9). When the first force transmission element (7) is in the bracing position, the second force transmission element (9) can be displaced in relation to the first force transmission element (7) in order to form the workpiece.
