Abstract

The invention provides a conical circular ring butt welding method and device. According to the method, six conical petals are welded into a conical circular ring by three steps; and the butt weldingdevice comprises a base structure, a beam pressing structure, a supporting structure, a mold tire, a movable frame structure and a plurality of key structures. According to the conical circular ring butt welding method and device, the technical problems that because the conical circular ring structure is special, the welding thickness is large and the structural rigidity is large, the conical cubicle assembling and welding difficulty is large when butt welding of the conical circular ring is carried out, and a method and a device in the prior art are not applicable are solved.

Description

technical field [0001] The invention belongs to the technical field of rocket tanks, and in particular relates to a tapered circular ring tailor welding method and device. Background technique [0002] The bottom of the storage tank of the active model rocket generally adopts a spherical bottom or an ellipsoidal bottom structure, which is composed of a top cover, a ring and a transition ring. , The circular ring is assembled and fixed by special tooling during tailor welding, and conventional TIG welding process can be used to realize non-groove butt welding. In the development of my country's new generation of manned launch vehicles, the rear bottom of the first-stage fuel tank adopts a five-meter-diameter conical bottom structure for the first time. Among them, the conical ring, an important part of the conical bottom structure, is composed of 6 conical rolling The melon petals are bent and welded, the cone angle of the melon petals is 90°, the longitudinal seam of the mel...
