Abstract

POSTUPAK ZA IZRADU IZ LIMENE PLOČE KOMADA U OBLIKU KOJI SE NE MOŽE RAZVITI I KOMAD OBLIKA DOBIJENOG OVIM POSTUPKOM, predmet ovog pronalaska je postupak za izradu iz limene ploče komada oblika koji se ne može razviti polazeći od limene ploče (10), naročito za izradu oborenih ivica, po kome se za svaku elementarnu površinu limene ploče (10) izračunava višak materijala koji se stvara deformacijom i skupljanjem materijala lima, definiše se najmanje jedna mreža perforacija (60, 70) tako da se izvuče iz svake elementarne zapremine odgovarajuća količina materijala prema varijaciji elementarne zapremine usled promene prvobitnog oblika limene ploče (10) da bi se dobio komad oblika koji se ne može razviti, bira se broj, raspored, dimenzija i oblik perforacija (60, 70), izradi se na limenoj ploči (10) pomenuta mreža perforacija (60, 70) i pod presom se deformiše limena ploča (10) da bi se dobio komad finalnog oblika koji se ne može razviti.
