Abstract

Dispozitiv pentru taierea de precizie a barelor din metal dur si semidur, conform inventiei principale nr. 57032, utilizat pentru taierea barelor trase si laminate, având forma si dimensiuni diferite în sectiune transversala, si la care eliminarea piesei taiate dupa desprinderea sa de cutit mobil de catre un mecanism, o face însusi semifabricatul în timpul avansarii pâna la un opritor fix, alcatuit dintr-un corp pe care se afla un cutit fix profilat si o semibucsa profilata de strângere prealabila a semifabricatului de catre o presa cu simpla actiune cu un mecanism prin intermediul unui excentric, caracterizat prin aceea ca, în scopul realizarii starii de tensiune de compresiune spatiala a materialului, a împanarii laterale si a torsionarii semifabricatului (4), este prevazut cu un subansamblu oscilant, portscula de taiere (B) articulat în corpul dispozitivului (1) printr-un bolt (2) având axa geometrica sub axa semifabricatului (19) strânsa cu o pârghie de actionare (16) articulata pe corpul transversal (14) al subansamblului oscilant (B) multiplicator de forta pentru a permite îmbratisarea si strângerea radiala puternica a semifabricatului (4) spre partea inferioara a corpului transversal (14) în care se afla un cutit profilat (15) la a carui coborâre simultana cu strângerea si torsionarea semifabricatului (4) efectueaza forfecarea pura dirijata a piesei de semifabricat (4) între cutitul mobil profilat (3) mentinute în contact frontal permanent cu o pana.Device for precision cutting of hard and semi-hard metal bars according to the main invention no. 57032, used to cut drawn and laminated bars having different cross-sectional shape and dimensions, and in which the removal of the piece cut after removal of the movable knife by a mechanism makes it semi-fabricate itself during advancing to a fixed stop, made up from a body on which there is a profiled fixed knife and a profiled semi-bucket of pre-clamping of the blank by a press with a simple action with a mechanism by means of an eccentric, characterized in that, in order to achieve the spatial compressive tension state (B) articulated in the body of the device (1) by means of a bolt (2) having a geometrical axis under the axis of the blank (19) of the material, of the lateral spinning and the torsion of the blank (4) (16) hinged to the transversal body (14) of the oscillating (B) force multiplier subassembly to allow (4) to the lower part of the transversal body (14) in which there is a profile knife (15), the simultaneous lowering of which with the tightening and torsion of the blank (4) performs the direct guided shearing of the semifinished piece (4) between the profiled mobile knife (3) held in permanent front contact with a blade.
