In the article, by using the direct method in the calculus of variations, the mechanism of deformation
force development in the matrix, when pressing rods in a new device with is considered, in addition the kinematics of
the process is analytically analyzed and the forces acting on the screw-like rolls of this device are calculated. On the
basis of the calculated data, it is established that the pressing stress decreases with increasing torques applied to the
screw-like rolls of the proposed device. It is proved that with increasing the value of the input angle of the matrix, the
forces and the pressing torque are increased. It is shown that the direction of friction forces exerts a significant
influence on the pressing stress. The smallest force and the pressing torque are obtained with an angle of friction
forces of 45°. The conducted researches made it possible to obtain new scientific data on the force parameters of rod
pressing on a new device, and the practical application of the results of the study will ensure an increase in the
efficiency of the manufacturing processes of bar products
