Abstract

Sposób wytwarzania tulei przelotowej polega na podgrzaniu materiału wsadowego, umieszczeniu go w cylindrycznej matrycy pod stemplem górnym (1) na suwliwej tulei oporowo-odcinającej (3) i poddaniu go procesowi wyciskania poprzez posuw stempla górnego (1) do momentu wyciśnięcia z materiału wsadowego tulei o grubości dna równej co najmniej jej grubości ścianki, następnie stemplem górnym (1) wykonaniu wyciskania tulei przy jednoczesnym wypychaniu z matrycy (2) tulei oporowo-odcinającej (3) aż do jej zablokowania, po którym stemplem górnym (1) następuje odcinanie dna wyciskanej tulei, po czym wypchnięcie dna przy pomocy stempla dolnego (6) otrzymując tuleję o przelotowym otworze odpowiadającym średnicy stempla górnego (1).The method of producing a through sleeve consists in heating the input material, placing it in a cylindrical matrix under the upper punch (1) on a sliding thrust and shut-off sleeve (3) and subjecting it to the extrusion process through the advance of the upper punch (1) until the sleeve material has been squeezed out bottom thickness equal to at least its wall thickness, then with the upper punch (1) squeezing the sleeve with simultaneous pushing out of the die (2) of the thrust and shut-off sleeve (3) until it is blocked, after which the upper punch (1) is followed by cutting the bottom of the pressed sleeve , then pushing the bottom with the bottom punch (6) to obtain a bushing with a through hole corresponding to the diameter of the top punch (1).
