A forging die includes on one face, a half-imprint of a part to be forged such as a turbine engine blade. The die also includes on the face, a device for forming a marking along two directions relatively to which the position of the imprint is defined, the device including two pads protruding relatively to the face and each including two notches defining the two directions. This device preferably includes two pads machined on the die at the same time as the imprint, and each including two notches in the form of a cross.

Forging die with marking means

The press of the invention includes a first component and a second component for holding and pressing a workpiece to be processed between them, the first component being driven into translation relatively to the second component by an air cylinder. Thus, the first component is floatably mounted relatively to the second component, said components comprising means for positioning them relatively to each other at the limit of travel. Proper centering of the workpiece between the components, without stresses, may thereby be provided.
