Abstract

The invention describes a method for roller levelling of strips with a maximum thickness of 4 mm by simultaneous stretching and bending by passing the strip (2) through a conventional roller levelling device with only two levelling rolls (1) but with a certain relation between the radiuses of the levelling rolls depending of the characteristics and thickness of the material in the strip (2).

Description

I\) O ÉO 35 S5 hårdnar det avsevärt p.g.a. kallbearbetningen. ÜPPFIï§IH EU: Det har nu överraskande visat sig att man kan plana plåtband f med endast två riktrullar om man förutom lämpligt drag andet [-4 n O; och lämplig storleksordning på brytrullarnas diameter, rätt av- \ passar inbördes förhållandet mellan rulldiametrarna. In \) O ÉO 35 S5 it hardens considerably due to the cold working. ÜPPFIï§IH EU: It has now surprisingly been shown that it is possible to plan sheet metal strips f with only two guide rollers if, in addition to a suitable pull, other [-4 n O; and suitable order of magnitude of the diameter of the breaking rollers, correctly matching the relationship between the rolling diameters.

Uppfinningen kommer att beskrivas i bifogade krav, i nedan gjord närmare beskrivning samt med hjälp av bifogade figurer varvid figur 1 beskriver schematiskt en ordinarie dragriktmaskin och figur 2 ett dragprovningsdiagram för bandmatrialet i fråga.The invention will be described in the appended claims, in the detailed description given below and with the aid of the appended figures, wherein figure 1 schematically describes an ordinary tensile straightening machine and figure 2 a tensile test diagram for the belt material in question.

IIÄPJJAPE BÉSZIEIVITIIIG AE' UPPFIIïIIIIIGElT: Han börjar med att ta ut dragprovbitar ur det plåtband ,2, som skall riktas, gör dragprov och uppritar på konventionellt sätt ett spännings- töjningsdiagram med töjningen ,É] efter abskissan och spänningen 1:5 efter ordinatan ,fig'2, (se Svensk standard SS 11 21 TO). Ban får då en från origo i stort sett rak, snett uppåt riktad linje, elasticitetslinjen ,?, upp till sträckgräns- punkten ,S, som sedan över~ar i en flackare linje, plasticerings- linjen ,9, Den senare linjen ,9, kan utan men för uppfinningen approximeras till en rät linje.IIÄPJJAPE BÉSZIEIVITIIIG AE 'UPPFIIïIIIIIGElT: He begins by taking tensile test pieces out of the sheet metal strip, 2 to be straightened, makes tensile tests and draws in a conventional way a stress-strain diagram with the strain, É] after the abscissa and the stress 1: 5 after the order 1: 5 '2, (see Swedish standard SS 11 21 TO). The web then has a substantially straight, obliquely upwardly directed line from the origin, the line of elasticity,?, Up to the yield point, S, which then turns into a flatter line, the plasticizing line, 9, The latter line, 9, can without harm to the invention be approximated to a straight line.

Kan väljer en radie ,R1, på första riktrullen ,1, som av tidi- gare erfarenheter av rullriktve_k bör vara omkring eller nâéot under 59 gånger plåttjock eken ,t, hos plå bandet ,2. rängs abskissan från origo i diagrammet ,fig 2, avsattes en iangd ,a, som är lika med plåttjockleken ,t, di iderad med första rullens ,1, w V radie 31 ocn från denna drares en fö a 9 å. rsta parallellinje ,10, upp mot plasticeringslínje: ,9, parallell med elasticitetslin- jen ,7. Därvid bildas en första yta ,11, i diagrammet ßig 2, mellan abskíssan, elasticitetslinjen ,7, första parallellinjen ,10, och plasticeringslinjen ,9. En ny andra parallellinje ,12, drages till höger om den första ytan ,11, och så att den andra ytan ,13, mellan abskissan, första och andra parallellinjen ,10;12, 3 och plasticeringslinjen ,9, blir lika stor som den första ytan ,11.Can choose a radius, R1, on the first directional roller, 1, which from previous experience of roller directional curves should be around or nâéot below 59 times the plate-thick oak, t, in the flat belt, 2. When the abscissa is drawn from the origin in the diagram, Fig. 2, a length, a, equal to the plate thickness, t, di isidated with the radius of the first roll, 1, w V radius 31 ocn is plotted from it, a first parallel line is drawn, 9 , up to the plasticization line:, 9, parallel to the elastic line, 7. Thereby a first surface, 11, is formed in the diagram ßig 2, between the abscissa, the line of elasticity, 7, the first parallel line, 10, and the plasticization line, 9. A new second parallel line, 12, is drawn to the right of the first surface, 11, and so that the second surface, 13, between the abscissa, the first and second parallel lines, 10; 12, 3 and the plasticizing line, 9, becomes equal to the first surface, 11.

'Y Avståndet ,b, längs abskissan mellan första och andra parallell- linjerna ,10;12, uppmätes. Plåttjockleken ,t, hos plâtbandet ,2, divideras nu med det senare avståndet ,b, och detta utgör nu radien ,R2, på den andra riktrullen ,1, i rullriktverket ,fig 1. Bessa två rullar användes sedan i ett rullriktverk Qfíg 1, av i inledningen beskrivna typ och plåtbandet ,2, riktas på vanligt satt med ¿änp1igt drag. Därvid erhålles ett plant plåtband ,2.'Y The distance, b, along the abscissa between the first and second parallel lines, 10; 12, is measured. The plate thickness, t, of the plate belt, 2, is now divided by the latter distance, b, and this now constitutes the radius, R2, on the second guide roller, 1, in the roller guide, Fig. 1. Two rollers were then used in a roller guide Qfig 1, of the type described in the introduction and the sheet metal strip, 2, is directed in the usual way with a simple pull. Thereby a flat sheet metal strip is obtained, 2.
