摘要

A method for cross rolling with flat tools of products such as balls, in particular the ones obtained from heads of scrap railway rails, consists in that billet ( 1) in the form of a head cut off a scrap railway rail is placed between initial wedges ( 4 and 5) located on one side of flat tools ( 2 and 3) , which then begin to move in the opposite directions with the same velocity ( V) , and the moving initial wedges ( 4 and 5) cut into the billet 1 and make it rotate, thereby forming a semi-finished product ( 6) in the form of a rod whose diameter ( D1 ) is bigger than or equal to the diameter ( D) of a ball ( 7) , next the flat tools ( 2 and 3) are stopped and the semi-finished product ( 6) is moved to the other side of the flat tools and placed between two wedges ( 8 and 9) which have longitudinal grooves ( 10 and 11) of a semi-circular profile, then the flat tools ( 2 and 3) make a return motion with the same velocity (V) , and during this time the wedges ( 8 and 9 ), which move in the opposite directions, form the balls ( 7) which are separated from one another by cutters ( 12 and 13) in the final stage of the rolling process. The process is done in a configuration wherein only one of the flat tools ( 2 or 3) moves in a sliding motion with the velocity ( V) , while the other tool ( 2 or 3) does not move.
