Abstract
Tehnologije preoblikovanja pločevinskih polizdelkov in izdelkov v malih serijah so se v zadnjih letih močno razširile. Večinoma se uporabljajo za preoblikovanje tanjše samostojne pločevine. Toda omenjene tehnologije bi bile lahko zanimive tudi za oblikovanje individualnih večslojnih konstrukcijskih elementov, kot so na primer fasade, strehe, itd. Ker so takšni konstrukcijski elementi običajno sestavljeni tudi iz kovinskih plošč, ki so predhodno vroče cinkane in barvane, je potrebno izbrati primerno tehnologijo preoblikovanja in njene stabilne procesne parametre, da med preoblikovanjem ne bi prišlo do nezaželenih poškodb. V tem prispevku so predstavljene posebnosti uporabe inkrementalnega preoblikovanja, kot dodatne tehnologije, pri oblikovanju večslojnih konstrukcijskih elementov. Posebna pozornost je usmerjena v popis preoblikovalnega procesa, vplive preoblikovanjana statiko večslojnega elementa in korozijsko obstojnost lokalno deformirane barvane kovinske plošče. Zadnji dve aktivnosti predstavljata najpomembnejše zahteve za zagotovitev konstrukcijskih standardovin garancijske dobe in sta popolnoma neodvisni od nepredvidljivih ostrih vremenskih pogojev. Ugotovljeno je bilo, da se statika večslojnega elementa lahko izboljša v primeru, če so uporabljeni primerni oblikovni parametri v povezavi s procesnimi parametri, pri čemer barvani sloj ostane nepoškodovan, tudi po zahtevnih antikorozijskih testih.

Abstract:
The technologies for low quantity production of sheet metal components and parts have expanded greatly in recent years. They are applied mostly for thin single metal sheets. However, such technologies could also be interesting to form individual multi-layer construction elements. As such construction elements consists of metal plates that are usually hot zinced and painted before forming process, it is necessary to select an appropriate technology with stable process parameters to avoid any damages. In this article, particularities of an incremental forming application as additional technology in multi-layer construction element production are presented. Special attention is dedicated to the forming principles, the forming influences on the mechanical properties of the multi layer element and the corrosion of the locally deformed coloured metal plate. The latter two activities represent the most important requirements in order to fulfil construction standards and due dates, both independently of unpredictable sharp weather conditions. It was discovered that the statics of the multi-layer element improves if appropriate shape parameters in connection with process parameters are applied, where the painted layer remains undamaged, even after demanding anticorrosion tests.
