Abstract
For transverse cutting of rolled products on mills, a shear machine with parallel knives is used. The permissible cross-sectional dimensions of rolled products, cut on this type of shear machine, are determined by the maximum force needed for cutting the bar in the cold state. It is obvious, that the lower the cutting force required, the lower the energy consumption. In order to reduce energy consumption during the rolled metal cutting at Siberian State Industrial University a cutting device for cutting a pre-bent bar has been developed in which the bar in the cutting zone under the action of gravity is bent due to the fact that the level of the outgoing roller table is located below the level of the approach roller table. A technique is proposed for calculating the force of cutting a pre-bent bar on the shear machine. The conditions are determined (the ratio of the length of the bar overhang and the difference in the levels of the approach and outgoing roller tables) for obtaining a qualitative cut when cutting the pre-bent bar. It is established that when cutting a pre-bent bar, the maximum cutting force is less than when cutting a straight bar.
