Abstract: The embodiment relates generally to a stamping or draw die used for forming a workpiece into a part or component using a first die shoe, a second die shoe and a punch wherein the punch draws the material into a cavity located in the second die shoe. The force is generated during the forming operation are often unbalanced which generates an uneven stress distribution on the component of the die assembly. By varying the position and angle of the guide surfaces located on the punch, first die shoe and second die shoe the stress can be distributed across a greater area of the respective die assembly component to reduce stress concentrations in a localized area and correspondingly reduce the potential for die failure.

Abstract: A high-pressure press includes a pressure vessel surrounded by a force-absorbing press frame. The high-pressure press also includes a detection structure for detecting changes in length of at least one column comprised in the press frame, the changes in length depending on the pressure inside the pressure vessel. The detection structure includes a limit switch, which is adapted to detect if the change in length of the column has reached a threshold value and, in that case, interrupt a pressing operation in progress and reduce the pressure inside the pressure vessel.
