Abstract

Postupak za oblikovanje limene ploce, narocito za izradu maske katodne cevi, koji se izvodi na presi, pri cemu se limena ploca (1) postavlja izmedu pritiskaca (20) i matrice (11), posle cega se vrsi stezanje sredisnjeg dela (1a) limene ploce (1) izmedu pritiskaca (20) i matrice (11), kada se vrsi oblikovanje sredisnjeg dela (1a) limene ploce (1) po definisanoj zakrivljenosti uz deformisanje odgovarajucih elemenata pritiskivaca (20) i matrice (11) pod dejstvom sila pritiska, i pri cemu je srednje vlakno sredisnjeg dela (1a) limene ploce (1) postavljeno u odredeni polozaj u odnosu na neutralno vlakno celog sklopa pritiskaca (20), limene ploce (1) i matrice (11) kada se vrsi i obaranje slobodnog perifernog dela (1b) limene ploce (1) kao i oblikovanje njegove oborene ivice, naznacen time, sto se vrsi izravnavanje elasticne zakrivljene osnove (24) pritiskaca (20) pri stezanju sredisnjeg dela (1a) limene ploce (1) postavljene na horizontalnu ravan elasticnog gornjeg dela (14) matrice (11), posle cega se vrsi oblikovanje sredisnjeg dela (1a) limene ploce (1) po definisanoj zakrivljenosti delovanjem ravnomerno rasporedenih sila po celoj povrsini pritiskaca (20) kada se limena ploca (1) defor-mise, zajedno sa gornjim delom (14) matrice (11) unutar udubljenja (12), pri cemu osnova (24) pritiskaca (20) zauzima prvobitnu zakrivljenost, i sto se posle zakrivljenja sredisnjeg dela (1a) limene ploce (1) vrsi aktiviranje dela (30) za periferno oblikovanje, kada se ovim aktiviranjem vrsi deformacija elasticnog nestisnjivog prstena (36) koji nalezuci na slobodni periferni deo (1b) limene ploce (1) vrsi njegovo kontrolisano savijanje, a pod stalnim pritiskom prstena (36) i slobodni periferni deo (1b) limene ploce (1) naleze duz bocnih zidova pritiskaca (20) oblikujuci njenu oborenu ivicu.
