Mechanics of Process of Rotational Tube Pressing-out Using 3-Roller Mill

A deformed state of a half-finished product, which is possible from the kinematic point of view, is analyzed in the plastic deformation area with specified boundary conditions and velocities when the product is pressed out at the rotational 3-roller mill. On the basis of this analysis a technique to calculate the motor power is offered, which allows choosing the required equipment for manufacturing thin-wall tubes during the 3-roller mill operation and design.
