Abstract

Dispozitiv pentru taierea de precizie a barelor trase si laminate din metal moale, cu autostrângerea semifabricatului, conform inventiei principale nr. 57032, alcatuit dintr-un corp între montantii caruia se deplaseaza un subansamblu mobil dintr-o semibucsa profilata de strângere prealabila a semifabricatului pe cutitul profilat fix de catre o presa cu simpla actiune, cu un mecanism de strângere prin intermediul unui excentric si dintr-o falca profilata strânsa cu doua pârghii de actionare legate pe corpul transversal al subansamblului mobil care face strângerea radiala a semifabricatului spre partea inferioara a corpului transversal în care se afla un cutit profilat caracterizat prin aceea ca, în scopul realizarii starii de tensiune spatiala a materialului, a unei precizii geometrice si dimensionale corespunzatoare a pieselor si a unei calitati superioare a suprafetei forfecate la coborârea subansamblului mobil (B) falca profilata (16) si cutitul mobil profilat (14) realizeaza îmbratisarea completa si strângerea radiala puternica a semifabricatului (3), dupa care are loc forfecarea pura, dirijata între cutitul mobil profilat (14) si cutitul fix profilat (2) precum si calibrarea piesei debitate prin opritorul fix (17) si cutitul fix (2), sprijinit cu o pana (20), dupa care piesa este eliminata de pe falca profilata (16) când se deplaseaza semifabricatul (3), prin orificiul opritorului schimbabil (17).Device for precision cutting of drawn and laminated soft bars, with the self-sharpening of the blank, according to the main invention no. 57032, consisting of a body between the uprights of which moves a movable subassembly of a semifinished profile of pre-clamping of the blank on the fixed profiled knife by a simple action press with a clamping mechanism by means of an eccentric and a the profile jaw tightened with two actuating levers connected to the transverse body of the movable subassembly which makes radial gathering of the blank to the lower part of the transverse body in which there is a shaped knife characterized in that in order to achieve the spatial tension state of the material (16) and the profiled mobile knife (14) perform the full engagement and the strong radial tightening of the blank (3), after which it is removed, pure shearing occurs between the profiled mobile knife (17) and the fixed knife (2), supported by a blade (20), after which the part is removed from the profiled jaw (16) when the blade (14) moving the blank (3) through the changeover stop (17).
