PRESSURE-SHAPING METHOD OF THIN-WALLED SHELLS |
摘要 |
FIELD: metallurgy. ^ SUBSTANCE: in surface sections of thin-walled shell, in which holes shall be made, there formed are closed cavities made with restricting devices in the form of a housing and matrix arranged inside the closed cavity. There used is matrix with sharp edge along its contact line with thin-walled shell, and closed cavity is filled with elastic medium. Proper directed force impact is applied with local pressure differential in the zone restricted with the closed cavity in order to make a hole. Holes are made in several sections of the shell per a cycle. ^ EFFECT: reducing labour input and facilities production costs. ^ 2 cl, 2 ex, 6 dwg |
