Abstract

Dispozitiv hidraulic pentru taierea de precizie a barelor trase si laminate având forma si dimensiuni diferite în sectiune transversala, cu autostrângerea semifabricatului, alcatuit dintr-un corp între montantii caruia se deplaseaza un subansamblu mobil si un mecanism de alimentare caracterizat prin aceea ca, în scopul realizarii taierii de precizie, prin forfecare pura dirijata, este prevazut cu un mecanism de fixare (A) a semifabricatului (5) cu ajutorul unei falci profilate (9) prin intermediul unor plunjere (6 si 7) si a unei pastile de hidroplast (8), subansamblu mobil (B) fiind alcatuit dintr-un corp (12) în care sunt montate un cutit profilat mobil (13) si o falca (14) profilata, care sunt actionate de o presa cu simpla actiune prinintermediul unor plunjere (15 si 17) si a unei pastile de hidroplast (16), realizând mai întâi strângerea radiala a semifabricatului (5) pâna la limita de curgere a materialului, ca urmare a deplasarii relative în sensuri opuse a corpului (12) si a plunjerului (17) dupa care la începerea deplasarii relative între corp (12) si plunjerului (17) are loc forfecarea pura dirijata a semifabricatului (15) datorita deplasarii subansamblului mobil (B), reglarea pozitiei acestui subansamblu (B) pe verticala fiind realizata de la un arc (20) a carui forta se regleaza cu un surub (21), compensarea micsorarii dimensiunilor cutitelor (4 si 13) profilate, dupa reascutire si mentinerea contactului permanent al acestora fiind asigurate cu o pana (23) în locul pastilelor de hidroplast (8 si 16) putând fi utilizat un alt agent hidraulic.Hydraulic device for precision cutting of pulled and laminated bars having different shape and dimensions in cross-section, with the self-shifting of the blank, comprising a body between the uprights of which moves a movable subassembly and a feed mechanism, characterized in that, in order to achieve (A) of the blank (5) by means of a plunger (9) by means of some plungers (6 and 7) and a hydroplast (8) pocket, , the movable subassembly (B) being made up of a body (12) in which a movable profiled knife (13) and a profiled jaw (14) are mounted, which are actuated by a simple action press through some plungers ) and a hydroplast pocket (16), first realizing the radial gathering of the blank (5) up to the material flow limit, as a result of the relative displacement in opposite directions of the body (12) and the plunger (17), the direct guided shearing of the blank (15) occurs due to the movement of the movable subassembly (B), the adjustment of the position of this subassembly (B) when the relative displacement between the body (12) and the plunger (20) whose force is adjusted by a screw (21), the compensating reduction of the dimensions of the profiled knives (4 and 13), after reassembly and maintaining the permanent contact of these, is provided with a screw (23) Hydraulic pills (8 and 16) may be used instead of the hydraulic agent.
