Abstract
The invention relates to a process for the production of corrugated workpieces made of a metallic material with at least one eccentric section in relation to its longitudinal axis. The process according to the invention in which the workpiece cut or sheared along a preset length and initially having a circular cross-section, is heated to a forging temperature corresponding to that of the material, is characterized by the fact that the heated workpiece is then deposited between two flat jaws, the two flat jaws are moved synchronously in parallel planes to each other and tangentially to the workpiece, which leads to a turning of the workpiece, and a bloom attached to a flat jaw, smaller in width than the total length of the workpiece, smaller in length uncoiling in the direction of circumference on the workpiece or equal to half the circumference of the workpiece and its height formed according to the prescribed eccentricity, displaces material of the workpiece and whereby the displaceme nt of the workpiece leads to the formation of the eccentric section and simultaneously to a change in length of the workpiece or laminations on the workpiece with a lateral limitation of the workpiece.
