Heat-Resistant Equipment for Bending Shaped Material with Electrical Heating,
Abstract
The improvement of airplanes has lead to expanded use in designs of shaped material of high-strength alloys which, as a rule, are hard to work. This has made it necessary to develop and implement new forming processes. One of the most promising forming processes for shaped parts, which drastically reduces labor sent in bending and finishing operations and which increases the precision of the part, is bending with tension using electrical contact heating of the billet. Optimal temperature forming intervals are: for aluminum and magnesium alloys 200-400 C, titanium alloys OT4 500-700 C, VT14 600-750 C, VT20 700-900 C, high-strength stainless steels 800-900 C.
