Abstract

Sposób walcowania wyrobów typu kula, zwlaszcza w wykroju spiralnym dwoma dyskami charakteryzuje sie tym, ze pólfabrykat (6) w ksztalcie odcinka preta o srednicy d mniejszej od srednicy D ksztaltowanej kuli (10) umieszcza sie w tulei (5) prowadzacej, nastepnie wprawia sie w ruch obrotowy tarcze (1) dolna i tarcze (2) górna ze stala predkoscia (n1) w przeciwnych do siebie kierunkach, po czym przesuwa sie pólfabrykat (6) ze stala predkoscia (V) w tulei (5) prowadzacej pomiedzy tarcza (1) dolna i tarcza (2) górna o osiach prostopadlych do osi pólfabrykatu (6), przy czym predkosc (V) przemieszczania sie pólfabrykatu (6) równa jest skokowi wystepów (3a), (3b), (3c) i (4a), (4b), (4c) spiralnych umieszczonych na powierzchniach roboczych tarczy (1) dolnej i tarczy (2) górnej, nastepnie wprawia sie pólfabrykat (6) w ruch obrotowy ze stala predkoscia (n2) i zaglebia sie wystepy (3a) i (4a) spiralne o klinowych powierzchniach (7a), (7b) i (8a), (8b) bocznych w pólfabrykat (6) i oddziela sie od pólfabrykatu (6) objetosc materialu równa objetosci ksztaltowanej kuli (10), po czym w wyniku oddzialywania wystepów (3b) i (4b) spiralnych o wkleslych powierzchniach (11a), (11b), (12a) i (12b) bocznych o promieniu równym promieniowi kuli (10) ksztaltuje sie w kule (10), zas przy uzyciu nozy (9a) umieszczonych na koncowych wystepach (3c) i (4c) spiralnych oddziela sie calkowicie uksztaltowana kule (10) od pólfabrykatu (6).The way of rolling ball-type products, especially in a spiral pattern with two discs, is characterized by the fact that the blank (6) in the shape of a rod section with a diameter d smaller than the diameter D of the shaped ball (10) is placed in the guide bushing (5), then put in rotary movement discs (1) lower and discs (2) upper with constant speed (n1) in opposite directions, after which the blank (6) moves with constant speed (V) in the sleeve (5) leading between the disk (1) lower and upper disc (2) with axes perpendicular to the axis of the blank (6), where the speed (V) of the blank movement (6) is equal to the pitch of the protrusions (3a), (3b), (3c) and (4a), ( 4b), (4c) spirally placed on the working surfaces of the lower disc (1) and upper disc (2), then the blank (6) is set in rotational motion with a constant speed (n2) and the projections (3a) and (4a) sink spiral with wedge surfaces (7a), (7b) and (8a), (8b) side in the blank (6) and branches it consists of a blank (6) volume of material equal to the volume of the shaped ball (10), and then as a result of the interaction of the protrusions (3b) and (4b) spiral with incised surfaces (11a), (11b), (12a) and (12b) side with a radius equal to the radius of the ball (10), it is shaped into spheres (10), while the completely shaped spheres (10) are separated from the semi-finished product (6) using the knives (9a) located at the end projections (3c) and (4c) of the spiral.
