Description

Technical Field

[0001] The invention relates to the technical field of bellows processing, and in particular to a feeding device for bellows processing. Background Art

[0002] Metal bellows is a tubular structure widely used in engineering fields in Northern Europe. It has a unique structure and performance. It is mainly used in prestressed concrete structures as a protective sleeve for prestressed tendons. It is pre-arranged before concrete pouring to ensure that the prestressed tendons can effectively transfer loads and prevent corrosion after tensioning. Concrete can be poured directly on the bellows. The metal corrugations on the surface of the bellows can make the concrete more firmly bonded to the bellows when it solidifies when it fits with the concrete. In addition, metal bellows are also used to compensate for deformation caused by thermal expansion and contraction, and to protect the stability and safety of the pipeline system. Due to the soft and retractable characteristics of the bellows, it helps to adapt to the deformation of the bridge when used on the bridge, while simplifying the installation process and reducing the difficulty of construction.

[0003] The manufacture of metal bellows requires the following steps: raw material welding, bellows forming, prestressing treatment and acceptance. The metal plate is bent and welded to form a metal tube, which is then fed into a bellows forming machine. The bellows forming machine extrude the metal tube through a die, causing corrugations to appear on the metal tube. When processing a long metal tube, it is necessary to manually feed the metal tube into the bellows forming machine repeatedly and take out the bellows after processing. The process of replacing the metal tube is labor-intensive, which affects the processing efficiency of the bellows.
