CROSS ROLL STRAIGHTENING MACHINE

摘要

Use: straightening of round bars and pipes. SUMMARY OF THE INVENTION: The machine comprises three two roll holder with the support and the pressing concave rollers (B), the length of which in extreme cages smaller than average. Profiles medium holder formed with a recess of the theoretical hyperboloid profile, has a profile in the Support with a recess, the maximum in the middle of its barrel and a decreasing smoothly to the ends, in a pressure equal to the maximum underestimation of the ends, umenshayuschees smoothly to zero by the middle barrel. The diameter of the neck of the pressure .raven neck diameter The side yokes, and the sum of the reference and pressure understating The constant along the length of any cross section perpendicular to the axis B. 1 ZP f ly-2-yl.
