Abstract
The utility model discloses 9-shpaed hollow cold bending profile steel. The cross section of the hollow cold bending profile steel is in a 9-shaped structure; the upper portion of the hollow profile steel of the cross section is in a rectangular shape; a long edge of the rectangular shape extends outside the rectangular shape; an end portion of the extension portion bends towards the internal side. The 9-shpaed hollow cold bending profile steel is large in bearing capability and stable in performance.
Description
Technical field
The utility model belongs to Lightweight Steel Shape technical field, especially relates to the hollow Lightweight Steel Shape of a kind of " 9 " font.
Background technique
Cold-bend hollow profiled bar pipe is a kind of economic section section bar, in steel building and engineering machinery vehicle, heavy equipment structure, and except using square tube, a large amount of steel tubing in different shapess that use Special Cross Sections also.Steel tubing in different shapes cold-forming shapes is because its section modulus is large, antitorque, shock resistance good, good stability, adds that present material selectable range is large, and the advantage with deep processings such as tensile bucklings, so present steel building and heavy equipment manufacture are all widely used.In some specific occasions, common cross section product can not be satisfied the demand, and need to process particular cross section clod wash product.
Summary of the invention
Not enough based on existing clod wash product cross section, the purpose of this utility model is: provide that a kind of bearing capacity is large, the hollow Lightweight Steel Shape of stable performance " 9 " font.
The technical solution of the utility model is: the hollow Lightweight Steel Shape of a kind of " 9 " font, hollow section for steel plate cold bending formation, the cross section of hollow section is " 9 " character form structure, the side of being, the top rectangle of hollow section on cross section, one long limit of side's rectangle extends outside square rectangle, the bending to the inside of the end of prolongation.
Further, prolongation comprises straightway and bending end, and the length of straightway and bending end is 10-32mm.
Further, square rectangle height H is 50-150mm, and width B is 50-100mm.
Further, the wall thickness T of hollow section is 5-12mm.
The beneficial effects of the utility model are: due to the similar Arabic numerals of sectional shape of the present utility model " 9 ", the side of being, top rectangle, one long limit of side's rectangle extends outside square rectangle, the bending to the inside of the end of prolongation, novel structure, its section modulus is large, anti-torsion, bending resistance are superior, stable performance, bearing capacity are large, safety, convenience, saving material, material selectable range is large, meet the practicality of special occasions, can be widely used in the industries such as steel building, heavy vehicle manufacture, special equipment manufacture, the manufacture of tower machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
