Conductive metal strip forming machine - has wire formed between saddle and anvil which are ultrasonically vibrated at different frequencies in inert atmos.

摘要

The metal strip is made from a metal wire, ultrasonic vibrations being imposed on the system and propagated at an angle to the longitudinal axis of the wire. The ultrasonic energy is used to prevent the welding of the metal to the tool under vacuum conditions or in inert medium and of high temperatures. The metal wire (3), the saddle (1) and the anvil (2) are placed in an inert medium relative to the metal of the wire, saddle and the anvil material. Subsequently wire is heated to the temperature of plastic deformation of the wire metal. Additionally the ultrasonic vibrations are imposed simultaneously to the saddle and the anvil. The frequencies of the vibrations imparted to the anvil are higher than those imparted to the saddle.
