SHAPING APPARATUS Russian patent published in 1997 - IPC

FIELD: plastic metal working, namely apparatuses for shaping in creep mode articles from titanium-base sheet materials. SUBSTANCE: apparatus includes rod-type shaping members contacting with material to be shaped in furnace cavity, and outside thermochamber apparatus includes controlling and loading drive units whose engaging and mutually moving members are isolated from furnace cavity due to increased length values of heat transfer circuits and their reduced cross section areas. Drive units setting deformation of blank are partially unloaded from efforts of loading drive units by braking systems, and they are connected with computer. Three rod-type members resting upon ball supports symmetrically arranged in the same plane correspond to each (loading or controlling) drive unit. Ends of rod members in furnace cavity have convex tips with curvature almost the same as curvature of articles. EFFECT: improved design. 4 cl, 12 dwg
