DEVICE AND PROCEDURE TO CONFORM WORK PARTS, ESPECIALLY TO CONFORM THEM IN COLD.

摘要

The invention relates to a device for cold forming, in particular for cold forming a part. This device comprises a formation matrix 83) and a feed system 85) which allows to produce a relative movement between the part (2) and the formation matrix (3). The device (1, 1 '') comprises a frequency generation system (10) that cooperates with the feed system (5) and allows the relative movement between the piece (2) and the forming matrix (3) to be modulated. produced by the feed system (5), such that after a feed path, during which the part (2) and / or then the forming die (3) travel in the direction of feed P a first path of travel, a movement of the formation matrix (3) and / or of the piece (2) can be carried out on a second travel path, during a consecutive return path, in a direction opposite to the direction of advance P.
