Abstract

L'invenzione concerne un dispositivo per introdurre sviluppi in stampi per imbutitura, comprendente un inseritore a comando programmato con una mano prensile contenente più ventose o elettromagneti per prelevare e rispettivamente deporre uno sviluppo. Lo stampo per imbutitura contiene una coppia di superfici di appoggio che bloccano congiuntamente lo sviluppo durante l'imbutitura. Per ottenere, specialmente in presenza di superfici di appoggio complicate dello stampo per imbutitura, ugualmente un pezzo imbutito di qualità costantemente elevata e per poter evitare scarti dovuti ad eventuali spostamenti dello sviluppo all'interno dello stampo per imbutitura che si chiude, la mano prensile è strutturata a forma di ragno prensile con almeno tre gambe comandabili con cui lo sviluppo prelevato, durante il trasporto dal luogo di prelievo allo stampo per imbutitura, è preformabile in forma definita ed è adattabile alla forma della superficie di appoggio del telaio di appoggio inferiore. Nella superficie di appoggio inferiore sono incassati profondamente in più punti organi adesivi comandabili sotto forma di ventose o elettromagneti per il ritegno di uno sviluppo preformato, inserito e collocato dal ragno prensile.
