NOZZLE-TO-HEADER CONNECTION METHOD, AND PLASTIC DEFORMATION DEVICE

摘要

FIELD: machine building.SUBSTANCE: connection of nozzles to a header is performed by plastic deformation (flaring) of ends of nozzles, which are inserted into the holes made in the header wall with a puncheon. First, the puncheon is located inside the header opposite the hole made in the header wall; at that, nozzle is restrained on outer side of the header. After the nozzle is attached to the header, the puncheon is influenced through the nozzle and turned to initial position.EFFECT: invention allows enlarging the range of technical equipment for connection of outlet pipes or nozzles to the header.8 cl, 5 dwg
