Abstract

Sposób walcowania skośnego trzema walcami stożkowymi, zwłaszcza wyrobów typu kula, charakteryzuje się tym, że półfabrykat (3) w kształcie odcinka pręta o mniejszej od średnicy kształtowanej kuli (5) umieszcza się w tulei (4) prowadzącej, po czym podaje się półfabrykat (3) do przestrzeni wejściowej trzech stożkowych walców (1a, 1b, 1c) roboczych, od strony czopów napędowych, następnie wprawia się w ruch obrotowy stożkowe walce (1a, 1b, 1c) robocze w tym samym kierunku i ze stałą prędkością (n1), po czym wprawia się półfabrykat (3) w ruch obrotowy ze stałą prędkością (n2) w kierunku przeciwnym do kierunku obrotów stożkowych walców (1a, 1b, 1c) roboczych oraz podaje się półfabrykat (3) ze stałą prędkością (V) w tulei (4) prowadzącej w kierunku spiralnych występów znajdujących się na stożkowych powierzchniach stożkowych walców (1a, 1b, 1c) roboczych, po czym zagłębia się spiralne występy o wklęsłych powierzchniach bocznych w półfabrykat (3) i kształtuje się na powierzchni półfabrykatu (3) przewężenie oraz oddziela się od półfabrykatu (3) objętość materiału równą objętości kształtowanej kuli (5), następnie zgniata się półfabrykat (3) spiralnymi występami.The method of oblique rolling with three conical rolls, especially of ball-type products, is characterized by the fact that a semi-finished product (3) in the shape of a section of a rod smaller than the diameter of the shaped ball (5) is placed in the guide sleeve (4), and then the semi-finished product (3) is fed ) into the input space of three conical working rolls (1a, 1b, 1c), from the side of the drive pins, then the conical working rolls (1a, 1b, 1c) are set in rotation in the same direction and at a constant speed (n1), after which sets the semi-finished product (3) in rotation at a constant speed (n2) in the direction opposite to the direction of rotation of the conical working rolls (1a, 1b, 1c) and feeds the semi-finished product (3) at a constant speed (V) into the sleeve (4) leading towards the spiral projections located on the conical surfaces of the conical working rolls (1a, 1b, 1c), and then the spiral projections with concave side surfaces are inserted into the blank (3) and a constriction is formed on the surface of the blank (3) and separated from blank (3) a volume of material equal to the volume of the shaped ball (5), then the blank (3) is crushed with spiral protrusions.
