Roll Forming Machine is designed for the production of metal structures of various types: narrow, corrugated, metal and other species. Today, roll forming equipment used by different structures and, furthermore, using different methods of profiling. However, the basic scheme does not change, a set of basic parts and components remained the same. Modern roll forming equipment – this automated production lines, which include everything needed to produce a device profile. Thus, as a raw material in roll forming machinery roll fed metal strip, and the output profile is obtained by a given cross-sectional shape and length, with the necessary perforations.
The basic working element, which includes any roll forming equipment – this mill. It consists of a series of pairwise arranged rolls, between which the metal billet. They give it the desired shape. In order to smooth the metal strip has become a curved profile (which can have a complex pattern), roll forming equipment should have several pairs of rollers, each of which will deform the workpiece stronger earlier. To achieve the effect using only one section (a pair of rolls) can not be destroyed by excessive metal pressure. However, there are roll forming equipment, which applies the method in the intensive deformation. It allows you to increase the bending angle profile obtained for the passage of one section, so the total number pairs of rollers is markedly reduced.
Forming equipment varies according to the method of profiling, which can be simultaneous or sequential. In the first case all the pairs of rolls all at once bent sheet metal. In second first deformed middle piece, and then (in the other sections) – its outer side. Forming equipment using the principle of simultaneous displays higher quality products, as material in this case exposed a uniform pressure, does not warp or lose strength properties. Sequential treatment, however, incorrectly distributes stress in the metal, which affects the quality the resulting profile.
