Description

technical field [0001] The invention belongs to the technical field of preforming thin-walled tubes, and in particular relates to a preforming device for thin-walled tubes with openings. Background technique [0002] The tube section of the open thin-walled tube is in the shape of an open thin-walled tube, which can realize the functions of folding and unfolding. Its main feature is that it can be wound and folded on the reel after being flattened. Bending stiffness, commonly used in monopole and dipole antenna ropes, gravity gradient stabilizer bars, support arms for sensors or cameras, and deployment support systems for solar sails. [0003] At present, the material of the existing thin-walled tubes with openings is usually metal, so it needs to be shaped by heat treatment. Before heat treatment and setting, a pre-forming process is required, that is, the flat strip is reliably wound on the outside of the mandrel, and then high-temperature heat treatment and setting can b...

Problems solved by technology

[0007] However, the open thin-walled tubes made by the above-mentioned manual preforming method are usually only suitable for thin-walled tubes with a short length within 1 meter, and cannot make long thin-walled tubes over 1 meter; The insertion force is achieved manually, and the insertion force is not uniform. Uneven insertion force often causes wrinkles at the opening of the thin-walled tube, which is prone to cracks and damage during use, reducing service life and increasing costs.
