Abstract

Procedimento di piegatura di una lastra di materiale deformabile, comprendente l'utilizzazione di un elemento premi-lastra per il bloccaggio orizzontale della lastra tra questo ed una opportuna incudine e il successivo azionamento di un utensile a coltello per l'operazione di piegatura, in cui detto azionamento di detto utensile a coltello consiste in un primo movimento di sola traslazione ed un secondo movimento di sola rotazione, ove detto primo movimento di traslazione produce una prima piegatura di 90° di un lembo di detta lastra e detto secondo movimento dì rotazione produce una seconda piegatura di detto lembo ad oltre 90°.Bending process of a sheet of deformable material, comprising the use of a plate-pressing element for the horizontal locking of the plate between it and a suitable anvil and the subsequent actuation of a knife tool for the folding operation, in which said actuation of said knife tool consists of a first movement of only translation and a second movement of only rotation, where said first translation movement produces a first 90 ° bending of a flap of said plate and said second rotation movement produces a second folding of said flap at more than 90 °.
