PRESS COMPRISING A TOOL-CENTERING DEVICE AND AND METHOD OF PRE-POSITIONING AND FIXING A TOOL ON A PRESS PLATEN

摘要

The invention relates to a press (1) for forming an object, including a bottom plate (2) and a top plate for receiving tools (3), as well as a drive that is provided to bring the plates (2) together so as to have the tools interact (3) therewith. The object to be processed is placed between said tools, said press (1) having a device (5, 12) for pre-positioning and a device (9, 11) for centering at least one tool (3) on at least one plate (2). A press according to the invention is mainly characterized in that the pre-positioning device involves at least one pre-centering pin (5) that is rigidly connected to the tool (3) and at least one groove (12) that is rigidly connected to the plate (2), said pin (5) being inserted into said groove (12) so as to enable guiding from a pre-positioning of the tool (3) on the plate (2), and in that the groove (12) has a locking means (15, 23) that makes it possible to rigidly hold the pin (5) in a predetermined position.
