Abstract
Sposób walcowania skosnego dwoma walcami spiralno - srubowymi wyrobów typu kula, charakteryzuje sie tym, ze pólfabrykat (3) w ksztalcie odcinka preta o srednicy (do) wiekszej od srednicy Dk ksztaltowanej kuli umieszcza sie w przestrzeni wejsciowej narzedzi utworzonej przez powierzchnie (5a) i (5b) stozkowe znajdujace sie na walcach (1a) i (1b) roboczych oraz pomiedzy dwoma prowadnicami (2a) i (2b), przy czym osie walców (1a) i (1b) roboczych nachylone sa pod jednakowym katem (?) w stosunku do osi pólfabrykatu (3) w plaszczyznie prostopadlej do plaszczyzny utworzonej przez prowadnice (2a) i (2b), oraz pod jednakowym katem ? w stosunku do osi wsadu (3) w plaszczyznie równoleglej do plaszczyzny utworzonej przez prowadnice (2a) i (2b), nastepnie wlacza sie ruch obrotowy walców (1a) i (1b) roboczych ze stala predkoscia (n1) w tym samym kierunku oraz ruch postepowy wsadu (3) ze stala predkoscia (V) w kierunku walców (1a) i (1b), w wyniku czego wprawia sie pólfabrykat (3) w ruch obrotowy ze stala predkoscia n2 w kierunku przeciwnym do obrotów walców (1a) i (1b) roboczych i redukuje sie srednice wsadu (3) przez powierzchnie (5a) i (5b) stozkowe do srednicy ksztaltowanej kuli, a nastepnie zaglebia sie klinowe wystepy (7a) i (7b) spiralne umieszczone na powierzchniach (6a) i (6b) stozkowych walców (1a) i (1b) roboczych we wsad (3) i oddziela sie od wsadu (3) objetosc materialu równa objetosci ksztaltowanej kuli, która nastepnie w wyniku oddzialywania wkleslych powierzchni (8a) i (8b) spiralnych.The method of rolling obliquely with two helical rollers of ball type products is characterized by the fact that the blank (3) in the shape of a rod section with a diameter (up to) greater than the diameter Dk of the shaped ball is placed in the entry space of the tool formed by surfaces (5a) and ( 5b) conical located on the work rollers (1a) and (1b) and between two guides (2a) and (2b), where the work axes (1a) and (1b) are inclined at the same angle (?) In relation to the axis of the blank (3) in the plane perpendicular to the plane formed by the guides (2a) and (2b), and at the same angle? in relation to the axis of the charge (3) in the plane parallel to the plane formed by the guides (2a) and (2b), then the rotational movement of the rollers (1a) and (1b) working with constant speed (n1) in the same direction and movement progressive charge (3) with constant speed (V) towards the rollers (1a) and (1b), as a result of which the blank (3) is set into rotation with constant speed n2 in the opposite direction to the rollers (1a) and (1b) ) and reducing the charge diameter (3) through the conical surfaces (5a) and (5b) to the diameter of the shaped ball, and then wedge protrusions (7a) and (7b) spiral located on the surfaces (6a) and (6b) conical of the work rollers (1a) and (1b) into the charge (3) and the volume of material equal to the volume of the shaped ball separates from the charge (3), which is then the result of interactions between spiral surfaces (8a) and (8b).
