Circumferential squeezing device for bar shape workpieces can be used for crcumferential squeezing of hollow or solid sections

摘要

Circumferential squeezing device for Circumferential squeezing of preferably bar shape workpieces with a hammer device (1), plungers (13) moving in radial guide elements. Each plunger has an external head (14) and an internal tool element (15), and a lifting force is applied to the plunger head from a lifting drive. The workpiece is deformed in the axial and/or radial directions by means of the individual plungers. An INDEPENDEN CLAIM is included for a method of circumferential squeezing of bar shaped workpieces.
