Claims (1)

Roll forming mill refers to the processing of sheet material by pressure using special-shaped rolls intended for use in ferrous metallurgy, transport engineering and construction in the manufacture of corrugated rolled sections. The roll forming mill contains a stand with forming drive rollers and additional non-drive rollers mounted on the guides in front of the stand. The guides are mounted on the crossbars in the racks with the possibility of installation movement parallel (along) the shelves of the resulting corrugated profile. The axes of the rollers are perpendicular to the guides, and the rollers themselves are installed with a certain pitch. From the rollers of the central guides, the lateral guides are displaced along the profile by a distance, from the point of contact with the roller of the front end of the workpiece to the occurrence of this workpiece to the full depth of the gauge. Combining the direction of rotation of the rollers with the direction of movement of the formed profile elements and installing from the center to the periphery of the rollers of each guide with an offset along the profile by a specified amount reduces energy consumption and reduces wear of the rollers while improving the quality of profiles, reduces the metal intensity of the mill and simplifies its adjustment.
