Abstract

Oppfinnelsen vedrører en fremgangsmåte og apparat for fremstilling av et kokekar, så som en stekepanne (12) eller en kjele, av et metallemne. Ifølge oppfinnelsen tilvirkes kokekaret ved rollformingsteknikker under anvendelse av et nedre verktøy (3), som roterer om sin akse (2), idet formflaten (6, 7) av det nedre verktøy er utformet slik at den tilsvarer den ytre flate av det fremstilte kar, og et øvre verktøy (5) som roterer om sin egen, separate akse (4), der profilen av den øvre verktøyflate (9, 10) tilsvarer den indre flate som formes på karet. Emnet plasseres på formflaten av det nedre verktøy, og verktøyene bringes deretter (3, 5) til å rotere slik at emnet roteres sammen med det nedre verktøy og flaten av det øvre verktøy er i lineær valsekontakt med emnet, hvorved metallet omformes i mellomrommet mellom verktøyene, idet metallet spres ut til den ønskede form av karet. Ved fremstillingen av stekepannen (12) kan emnet være et plateliknende metallstykke, hvorved pannens stigende kanter dannes under rollformingen ved at emnet sprer seg radielt utover ved sine kanter. I forbindelse med formningen kan inner- og ytterflaten utstyres med mønstre som består av fremspring og/eller forsenkninger.This invention relates to a method and apparatus for making a cookware, such as a frying pan (12) or a kettle, of a metal blank. According to the invention, the cookware is manufactured by roll forming techniques using a lower tool (3), which rotates about its axis (2), the mold surface (6, 7) of the lower tool being designed to correspond to the outer surface of the manufactured vessel. and an upper tool (5) rotating about its own separate axis (4), wherein the profile of the upper tool surface (9, 10) corresponds to the inner surface formed on the vessel. The blank is placed on the mold surface of the lower tool, and the tools are then rotated (3, 5) so that the blank rotates with the lower tool and the surface of the upper tool is in linear rolling contact with the blank, thereby transforming the metal into the space between the tools. , the metal spreading to the desired shape of the vessel. In the manufacture of the frying pan (12), the blank may be a plate-like piece of metal, whereby the rising edges of the pan are formed during roll forming by the blank spreading radially outward at its edges. In connection with the molding, the inner and outer surfaces can be equipped with patterns consisting of projections and / or countersinks.
