The invention concerns an arrangement for plastic forming of material in cold and hot condition, especially for plastic forming by cold extrusion with co-extrusion, cup extrusion with counterflow, and drop forging. The arrangement has a container 1 for the processing material 7, a stamp 2 and a die, which consists of elements arranged moveable with respect to each other 3, 4, 5, 6, which by one end come into contact with the processing material and by the other end come into contact with corresponding intermediate elements 8, 9, 10, 11. One 8 of the intermediate elements 8, 9, 10, 11 is supported by a disk 20, which is rigidly fastened to one side of a housing body 15, while the other intermediate elements 9, 10, 11 are supported on corresponding cylindrical supports 12, 13, 14, which extend moveably against openings in the disk 20 and make contact with support elements 16, 17, 18, which are concentrically inserted in each other with guaranteed- play fitting and packings. The outermost support element 18 is moveable and inserted with a packing in an opening in the housing body 15, which is provided with a cap 19, which hermetically closes the opening in the housing body 15. The space in the housing body 15 between the cap 19 and the support elements 16, 17, 18 is filled with a fluid and connected via a pressure reducing unit 22 to a container 23 which is filled with an elastic medium and provided with a check valve 24 and elements 25, 26 for measuring and limiting the pressure of the elastic medium. <IMAGE> |
