Steel-aluminum composite corrugated pipe compensator and manufacturing process thereof

Abstract

The invention discloses a steel-aluminum composite corrugated pipe compensator and a manufacturing process thereof. The compensator comprises an upper flange and a lower flange. Composite corrugated pipes are fixedly connected between the opposite sides of the upper flange and the lower flange. The outer surface of the upper flange and the outer surface of the lower flange are each fixedly connected with a plurality of supporting plates. The tops of the supporting plates are fixedly connected with set bolts correspondingly. Double-end threaded rods are connected between the inner surfaces of the set bolts located above and the inner surfaces of the set bolts located below in a threaded manner. According to the steel-aluminum composite corrugated pipe compensator and the manufacturing process thereof, by arranging fixed arc blocks and movable arc blocks in a welding device, the arc blocks are matched with adjusting bolts and adjusting screw nuts, so that upper flanges are fixed to corresponding lower flanges; meanwhile, a supporting arc plate supports a composite corrugated pipe, so that the composite corrugated pipe is stably welded; and in addition, a servo motor is used for driving rotating plates to rotate, the composite corrugated pipe can be turned over, welding personnel do not need to excessively adjust the angle, and the production efficiency is improved while the labor force is reduced.

Description

technical field [0001] The invention relates to the technical field of bellows compensators, in particular to a steel-aluminum composite bellows compensator and a manufacturing process thereof. Background technique [0002] The bellows compensator belongs to a kind of compensation element, also known as the bellows expansion joint, which is an expansion joint made of metal bellows. It can expand and contract along the axial direction, and also allows a small amount of bending. It is mainly used for axial length compensation. Utilize the effective telescopic deformation of the bellows of its working body to absorb the dimensional changes caused by thermal expansion and contraction. [0003] The Chinese patent discloses a steel-aluminum composite bellows compensator and its manufacturing process (publication number: CN109027493A), including a round flange, a square flange and a bellows. The bellows is a double-layer bellows structure, and its inner layer is a stainless steel ...

AI Technical Summary

Problems solved by technology

[0004] At present, when manufacturing steel-aluminum composite bellows compensators, each part needs to be welded. However, during welding, the welding angle often needs to be moved. Therefore, during welding, not only the parts need to be moved frequently, but also the position must be changed. Therefore, Extremely inconvenient when welding, resulting in low production efficiency
