Abstract

Sposób walcowania poprzecznego dwoma walcami śrubowymi wyrobów typu kula charakteryzuje się tym, że półfabrykat (4) w kształcie pręta o średnicy mniejszej od średnicy kształtowanej kuli wprowadza się do przestrzeni roboczej narzędzi, utworzonej przez dwie nieruchome prowadnice (3a, 3b) oraz walec (1) i walec (2) o osiach równoległych do osi półfabrykatu (4), przy czym na powierzchniach cylindrycznych walca (1) i walca (2), w ich strefie wejściowej, znajdują się występy (7, 8) pierścieniowe, usytuowane równolegle do powierzchni czołowych walca (1) i walca (2), gdzie występy (7, 8) pierścieniowe posiadają wklęsłe powierzchnie boczne o promieniu równym promieniowi walcowanej kuli (6), następnie uruchamia się ruch obrotowy walca (1) i walca (2) w tym samym kierunku i z taką samą prędkością (n1), po czym wprawia się półfabrykat (4) w przeciwbieżny ruch obrotowy z prędkością (n2) i zagłębia się w półfabrykat (4) występy (7, 8) pierścieniowe oraz kształtuje się na obwodzie półfabrykatu (4) pierścieniowy rowek. W wyniku oddziaływania występów (12, 13) śrubowych o wklęsłych powierzchniach (14a, 14b, 15a, 15b) bocznych, znajdujących się w strefie kształtowania walca (1) i walca (2) przemieszcza się półfabrykat (4) ruchem śrubowym wzdłuż osi walca (1) oraz walca (2) i jednocześnie redukuje się średnicę pierścieniowego rowka o sferycznych powierzchniach bocznych, ukształtowanego przez występy (7, 8) pierścieniowe.The method of transversal rolling with two helical rollers of ball type products is characterized by the fact that the rod (4) in the shape of a rod with a diameter smaller than the diameter of the shaped ball is introduced into the working space of the tools formed by two fixed guides (3a, 3b) and a roller (1) and a cylinder (2) with axes parallel to the axis of the blank (4), where on the cylindrical surfaces of the cylinder (1) and the cylinder (2), in their entrance zone, there are ring projections (7, 8), located parallel to the front surfaces cylinder (1) and cylinder (2), where the ring projections (7, 8) have concave side surfaces with a radius equal to the radius of the rolled ball (6), then the rotational movement of the cylinder (1) and the cylinder (2) starts in the same direction and at the same speed (n1), after which the blank (4) is put in a counter-rotating rotation with the speed (n2) and sinks into the blank (4) ring projections (7, 8) and on the perimeter of the blank (4) is an annular groove. As a result of the impact of screw projections (12, 13) with concave lateral surfaces (14a, 14b, 15a, 15b) located in the shaping zone of the roller (1) and the roller (2), the blank (4) moves with a helical movement along the roller axis ( 1) and the cylinder (2) and at the same time the diameter of the annular groove with spherical lateral surfaces shaped by the protrusions (7, 8) is reduced.
