The invention discloses a closed sectional material, an on-line manufacturing method of the material, and a special production device for the method. The on-line manufacturing method of the closed sectional material comprises processes of punching, bending and filling for producing a closed plate material, wherein before the plate material is bent, through holes for pouring filling materials are punched in the plate material, the filling materials can be poured into a cavity of a hollow sectional material by a filling needle of a filing device through the through holes, and the hollow sectional material is filled so as to obtain the closed sectional material filled with the filling materials, so that the filling working procedure of the closed sectional material is transferred to the production line of the closed sectional material, and is combined organically with the bending working procedure. Therefore, the production cycle of the closed sectional material is shortened, and the production efficiency of the closed sectional material is improved.
Description
technical field [0001] The invention relates to the technical field of closed profile production, in particular to an on-line manufacturing method of a closed profile, and also relates to a production device dedicated to the on-line production method of a closed profile. Background technique [0002] The existing closed profiles generally use the method of cold bending forming, which is made by bending steel coils. For example, the Chinese invention patent with application number 200910085560.0 discloses a forming and welding process of closed cold-formed steel, which discloses that steel coils are cold-formed and welded to obtain required hollow profiles. At present, when filling such hollow profiles, it is necessary to manually inject polyurethane foam into the cavity of the hollow profiles outside the production line, that is, first cut off the hollow profiles on the production line, and then offline The polyurethane foam material is filled into the hollow profile throug...
