Abstract

Sposób walcowania poprzecznego odkuwek z osiowym przemieszczaniem wsadu, zwlaszcza walcowania osiowosymetrycznych odkuwek walków stopniowanych charakteryzuje sie tym, ze pólfabrykat w postaci preta umieszcza sie miedzy dwoma prowadnicami (2a) i oraz miedzy dwoma jednakowymi walcami (1a) i (1b) roboczymi o osiach równoleglych do siebie, na powierzchniach których wykonane sa srubowe wystepy w ksztalcie klinów, nastepnie uruchamia sie ruch obrotowy walców (1a) i (1b) roboczych w tym samym kierunku i z taka sama predkoscia (n1), w efekcie wcina sie wejsciowe powierzchnie (4b) klinowe umieszczone na walcach roboczych (1a) i (1b) w pólfabrykat i wprawia sie go w ruch obrotowy z predkoscia (n2) w kierunku przeciwnym do kierunku obrotu walców (1a) i (1b) roboczych, a nastepnie ksztaltuje sie na obwodzie pólfabrykatu pierscieniowy rowek za pomoca klinowych powierzchni (5b) prowadzacych, po czym w wyniku oddzialywania srubowych powierzchni klinowych (6a) i (6b) rozszerza sie pierscieniowy rowek na pólfabrykacie oraz redukuje sie srednice pólfabrykatu i jednoczesnie przemieszcza sie pólfabrykat ze stala predkoscia wzdluz jego osi w kierunku nozy (8b) odcinajacych, nastepnie w wyniku oddzialywania klinowych powierzchni (7a) kalibrujacych usuwa sie nierównosci uksztaltowanej odkuwki (9), która w ostatniej fazie procesu odcina sie od pólfabrykatu za pomoca nozy (8b) odcinajacych umieszczonych na powierzchni walców.The way of cross-rolling of forgings with axial displacement of the charge, especially the rolling of axisymmetrical forgings of stepped rollers is characterized by the fact that the blank in the form of a rod is placed between two guides (2a) and between two identical cylinders (1a) and (1b) working axes parallel to themselves, on the surfaces of which there are screw protrusions in the shape of wedges, then the rotational movement of the work rollers (1a) and (1b) starts in the same direction and with the same speed (n1), as a result, the input wedge surfaces (4b) are cut on the work rollers (1a) and (1b) into the blank and set it in rotational motion at a speed (n2) in the opposite direction to the rotation of the work rolls (1a) and (1b), and then a ring groove is formed around the blank by means of the guide wedge surfaces (5b), after which as a result of the action of the screw wedge surfaces (6a) and (6b) the rings widen this groove on the blank and the diameter of the blank is reduced and at the same time the blank moves with a constant speed along its axis towards the cutting knives (8b), then as a result of the action of wedge surfaces (7a) calibrating removes the unevenness of the shaped forgings (9) which the process phase is cut off from the blank by means of cutting knives (8b) located on the surface of the rollers.
