Abstract

A deep-drawing press having at least two embossing dies of different sizes, an outer punch or punch for embedding a workpiece through the larger of the two dies, an inner punch or die for re-embossing the workpiece. work through the smaller die, and means for relatively moving the dies and dies in a working stroke of the press, plugging the inner die with the outer die and having a housed relationship with the outer die during the drawing operation to through the larger die, the press being characterized by the provision of means to limit the relative movement of approach between the outer die and the smaller die to define a step for the deformation of a work piece between the end of the outer die and a superficial part of the smaller matrix that extends inwards in the direction of the path of movement of the troq internally, and by means for applying a force to the outer die during the movement for re-embossing the inner die to maintain a fixed relationship between the end of the outer die and said surface part of the smaller die, forming the inner die and a second surface part of the smaller die, generally extending parallel to the path of movement of the inner die, an axially extending passage, having a width less than the thickness of the workpiece at least with respect to the end rear of a workpiece drawn through the passage extending axially by the movement of the inner die.
