Abstract

Inventia se refera la o masina de rasfrînt capete la tevi, prin deformare plastica la rece. Masina se compune dintr-un sasiu pe care sînt fixate doua dispozitive, unul de deformare si unul de strîngere, cît si o cale de rulare, pe care ruleaza niste carucioare care sustin teavade prelucrare. Dispozitivul de deformare, cuprinde un cilindru hidraulic, pe tija caruia este fixata o placa de aplatizare, pe care, se sprijina alternativ un dorn echipat cu bacuri deplasabile radial, sau un trunchi de con pentru operatia de evazare a capatului tevii. Deplasarea radiala a bacurilor, formeaza la capatul tevii un prag care preia în fazele urmatoare efortul axial si-l transmite dispozitivului de strîngere.The invention relates to a machine for deflection of pipes heads by cold plastic deformation. The car is made up of a chassis fitted with two devices, one for deformation and one for clamping, and a treadmill, running on trolleys supporting the machining process. The deformation device comprises a hydraulic cylinder, on the rod of which is fixed a flattening plate, which alternatively supports a mandrel equipped with radially displaceable holes, or a truncated cone for the pipe end flap operation. The radial displacement of the ferrules forms at the end of the pipe a threshold which takes the axial strain into the following phases and transmits it to the clamping device.
