METHOD OF PRODUCING WELDED THIN-WALL CONICAL SHELL WITH LENGTHWISE CRIMPS |
摘要 |
FIELD: process engineering.SUBSTANCE: invention relates to production of welded thin-wall conical shell with lengthwise crimps, used for example as a heat shield of gas turbine engine nozzle. Shell segments are formed. Said segments are arranged at the bed shaped to truncated cone and furnished with the flange placed at larger-diameter end and supports arranged at said conical surface along generating lines. Segments crimps are placed at supports and locked at the bed. Then, stiff squeezer carcass composed of conical frame consisting of end flanges is arranged coaxially at said bed over its segments. Larger-diameter end flange is shaped to ring. All said flanges are interconnected by lengthwise strips with pressure elements arranged thereon. Frame ring-like flange and bed flange are tightened together. Then, segments are finally locked by thrusting them by pressure elements against conical surface. Lengthwise edges of adjacent are welded to unlock made shell and to remove it from the bed.EFFECT: simplified process, expanded process performances.6 dwg |
