    • 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.
    • 用于形成工件(2)的端部,特别是用于冷压成形的管端,具有两个在一个共同的壳体(3)的动力传递元件(7,9)的特征在于,所述两个动力传递元件之间运行的设备(7,9) 的第一压力室(26)被布置和所述第二力传递元件(9)的第二压力室(28)被分配,其中,在所述夹紧位置属性的第一力传递元件(7)的第二力传递元件(9),用于将所述工件(相对于所述第一力传递元件 7)是可移动的。
