ABSTRACT:
The method forms a part in relief on a sheet metal blank (10) by means of a die and a punch. There are carried out on at least a localized zone of the blank (10 of FIG. 2), whose dimension exceeds the dimension of the part in relief, a preforming operation and a shaping operation resulting in the forming of the part in relief. In the course of the preforming operation, a succession of stepped undulations are progressively produced in an intermediate zone of the localized zone located between the future high part of the part in relief and the periphery of the localized zone, and, in the course of the shaping operation, the stepped undulations of the intermediate zone are progressively unfolded and the part in relief is simultaneously formed. The invention also provides a device for carrying out this.
