That is, the press die (not shownlprotrtides through the bore 5 of the ram bearer 1 and strikes a bottom die (not shown) disposed coaxially to and in the path of movement of the first press die. The movement of the press die against the bottom die carries out the desired noncutting reshaping operation on the pressed part.
  • the bottom die as well as the driving and guiding elements of the press slide 2 have not been shown for the sake of clarity since they are not essential to the understanding of the invention.
  • the ram bearer bores 3 are deliberately kept larger than the diameter of the respective pertinent attaching screws 6, (FIG. 2). This size relationship between the bores 3 and screws 6 allows for the ram bearer l to be adjusted in its position at any time after the attaching screws 6 are released. At the same time, the difference between the diameter of the bearer bores 3 and the outside diameter of the attaching screws 6 must correspond at least to the maximum range of the desired adjustment.
