PROCEDURE FOR MANUFACTURE OF BELLOWS AND FACILITY FOR IMPLEMENTATION OF THIS PROCEDURE Russian patent published in 2010 - IPC F16J3/04 

FIELD: machine building.

SUBSTANCE: in procedure there are used work-pieces of square shape. At connection the work-pieces are subjected to ultra-sonic oscillations. Further, there are made cuts along perimetre of processing, making an accurate shape of bellows. The first insulator, the first electrode with the first inducer and a hold-down disk are installed on a base of the facility. Also a movable part consists of a pusher connected to a flange; a circular knife and a spring are mounted on the flange through an adjusting ring. Further, the movable part consists of a stop whereon there is positioned a cartridge with an ultra-sonic converter and of the second insulator whereon there is mounted the second electrode with the second inducer and a thermocouple. A guiding sleeve and the ultra-sonic converter with a concentrator are mounted on the base in the facility for manufacture of bellows by means of connection of work-pieces along external diametre. A thermocouple and the first electrode with the first inducer are secured to the concentrator through the first insulator. A guiding cartridge is arranged on the sleeve. Also the movable part consists of the pusher connected with a mandrel through the adjusting ring. A flange with a spring is positioned on the mandrel with the circular knife attached to the flange and to the stop with the secured thereon guiding bushing; the second electrode with the second inducer is installed through the second insulator.

EFFECT: upgraded quality, processability, and reduced prime cost of manufacture.
