Abstract

The subject of the invention is a process for drawing metal blanks (1) for the manufacture of so-called deep-drawn components. The process consists in clamping the peripheral part of the metal blank (1) between a die (2) and a blank holder (4), in applying a drawing force to the die (2) and simultaneously in applying a retaining force to the blank holder (4), this retaining force being opposed to and less than the drawing force in order to obtain the final depth of the pressing, in applying a reduced retaining force to the blank holder (4), this reduced retaining force being between a fifth and a half of the said retaining force in order to obtain a first pressing of a depth lying between a fifth and a third of the final depth. The subject of the invention is also a device for drawing metal blanks for the implementation of the process. <IMAGE>
