Method of transverse rolling of ball-type goods, especially the heads of scrapped rails

摘要

A method for cross rolling of products such as balls, in particular the ones obtained from heads of scrap railway rails, whereby billet ( 1 ) in the form of a head cut off a scrap railway rail is placed between two flat tools ( 2 ) and ( 3 ) which have initial wedges ( 4 ) and ( 5 ), behind which there are wedges ( 6 ) and ( 7 ) which have longitudinal grooves ( 8 ) and ( 9 ) of a semicircular profile, next the flat tools ( 2 ) and ( 3 ) begin to move in the opposite directions with the same velocity ( V ), and during this time the moving initial wedges ( 4 ) and ( 5 ) cut into the billet ( 1 ) and make it rotate, thereby forming a semi-finished product (1 0) which has the form of a rod whose diameter ( D1 ) is bigger than or equal to the diameter ( D2 ) of a ball ( 11 ), next the wedges ( 6 ) and ( 7 ) with the grooves ( 8 ) and ( 9 ) cut into the semi-finished product ( 10 ) and form the balls ( 11 ), which are in the final stage of the rolling process separated from one another by cutters (12) and ( 13 ) located at the end of the flat tools ( 2 ) and ( 3 ). 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.
