Abstract
In an automatic stamping press with an exchangeable tool, the guide of the press plunger and the press table is utilized for guiding the tools. To this end, guideless tools with an upper tool part and a lower tool part are fastened as separate tool halves directly to the press plunger and the press table respectively. At both the press plunger and at the press table, at least one positioning device is provided by which the position of the upper tool part at the press plunger and the position of the lower tool part at the press table can be set exactly. The positioning devices are hydraulic positioning plugs. If an adjustment gauge is used, the hydraulic positioning plugs can be set at the press plunger and the press table so that subsequently, the tool halves can be mounted without further adjustment in accurate positions and reproducibly at any time.
