Abstract: The study of the regularities of sheet metal straightening, creation of new equipment for roller straightening machines (RSM) are relevant and are of great scientific and practical importance.
The aim of the study is to develop a roller straightening machine for levelling strips of corrosion-resistant steels.
The complexity of the machine design and the increased installed power of the main drive, the need for which is dictated by the use of several pairs of tension rollers at the input and output tensioning stations, as well as increased tension during straightening of strips, reduce the efficiency of traditional levelers. A new design of the RSM for straightening strips of corrosion-resistant steels is presented, the advantage of which is: simplicity of design, as well as a decrease in the installed power of the main drive. Dependencies are obtained for calculating the forces generated when the roller unit of the machine is loaded by the straightening force, as well as the torque on the intermediate drive rollers. The calculation of the torques was performed on the intermediate drive rollers when straightening a strip of steel 12X18H10T with a thickness of 1.2 mm with an initial curvature of 0.001-002 on a roller of small diameter 50 mm. It has been stated by calculation that the installed power of the main drive electric motor when straightening strips made of corrosion-resistant steel 12X18H10T with a thickness of 1.2 mm is 160 kW, which is significantly less than the installed power of the main drive electric motor of a traditional RSM.
