FIELD: metal shaping under pressure, processes of pipe fixation in pipe lattice during localized directed plasticized deformation of pipe material in particular. SUBSTANCE: pipe 2 is mounted with clearance in pipe lattice 1, that has holes with ring-type grooves. End of pipe 2 has ring-type groove made from side of its inner surface with length exceeding space between ring-type grooves in lattice. Pipe mounting is exercised positioning ring-type groove in zone of butt surfaces of lattice ring-type grooves. Axial effort "P" is applied only to part of pipe butt area, providing its movement in respect to lattice. Simultaneously free volumes of lattice ring-type grooves are filled due to free bending of pipe along their location. EFFECT: improved process of pipe fixation in pipe lattice. 5 cl, 4 dwg |
