Abstract
Sposób kształtowania czopów wałków długich w układzie pojedynczym, zwłaszcza narzędziami obrotowymi polega na tym, że jeden z końców półfabrykatu w kształcie odcinka pręta o średnicy równej średnicy maksymalnej odkuwki wałka (16) i długości większej od szerokości narzędzi L3 nagrzewa się lokalnie na długości L4 kształtowanych stopni do temperatury powyżej temperatury rekrystalizacji, po czym umieszcza się nagrzany koniec półfabrykatu w strefie wejściowej dolnego walca roboczego i górnego walca roboczego (2) oraz pomiędzy dwiema prowadnicami (19 i 20) i ustala się położenie półfabrykatu w strefie wejściowej dolnego walca roboczego (1) i górnego walca roboczego (2) przy pomocy występów ustalających (11), zaś nienagrzaną część półfabrykatu umieszcza się w tulei prowadzącej (3), następnie wprawia się dolny walec roboczy (1) i górny walec roboczy w ruch obrotowy w tym samym kierunku z jednakową prędkością (n1) i obraca się dolny walec roboczy (1) i górny walec roboczy nad nagrzanym końcem półfabrykatu, po czym zagłębia się w nagrzany koniec półfabrykatu klinowe występy (5 i 6) znajdujące się na powierzchniach cylindrycznych dolnego walca roboczego (1) i górnego walca roboczego i wprawia się półfabrykat w ruch obrotowy, następnie oddziaływuje się na nagrzany koniec półfabrykatu (4) bocznymi pochyłymi powierzchniami (7a i 7b) oraz (8a i 8b) klinowych występów (5 i 6) dolnego walca roboczego (1) i górnego walca roboczego.The method of forming long shaft pins in a single system, especially with rotary tools, is that one of the ends of the blank in the shape of a rod section with a diameter equal to the maximum diameter of the shaft forgings (16) and a length greater than the width of the tools L3 heats locally along the length L4 of the shaped steps to a temperature above the recrystallization temperature, after which the heated end of the blank is placed in the entrance zone of the lower work roll and upper work roll (2) and between the two guides (19 and 20) and the position of the blank in the lower work roll (1) is determined and the upper work roll (2) by means of retaining lugs (11), while the unheated part of the blank is placed in the guide sleeve (3), then the lower work roll (1) and the upper work roll are rotated in the same direction at the same speed (n1) and the bottom one rotates the work roller (1) and the upper work roller over the heated end of the blank, after which the wedge-shaped protrusions (5 and 6) located on the cylindrical surfaces of the lower working roll (1) and the upper working roll sink into the heated end of the blank and the blank is set in motion rotary, then acts on the heated end of the blank (4) with lateral inclined surfaces (7a and 7b) and (8a and 8b) wedge-shaped projections (5 and 6) of the lower work roll (1) and the upper work roll.
