Abstract

Inventia se refera la o masina de îndoit tevi, avînd toate actionarile hidrostatice, functionînd în ciclu automat sau manual, tevile putînd fi îndoite la rece sau la cald, cu sau fara dorn. Masina pentru îndoit tevi este formata dintr-un batiu pe care este montat un suport mobil ce executa miscarea principala de îndoire a tevii, sectionat de un cilindru de forta, un cilindric hidraulic aducînd suportul mobil în pozitia initiala, sprijinirea tevii facîndu-se pe un suport cu role, glisant de-a lungul unui suport fix montat pe batiu. Masina este prevazuta cu un dispozitiv de limitare a unghiului de îndoire care are un tambur cu opt sau mai multe canale longitudinale gradate, în fiecare canal fixîndu-se cîte un opritor ce actionat de tija cilindrului hidraulic deplaseaza tamburul, acesta printr-o pîrghie oscilanta actionînd asupra unui limitator electric opreste alimentarea cu ulei a cilindrului de fonta, deci si miscarea de rotatie a suportului mobil, fiind asigurata de o contragreutate care printr-un cablu montat pe o rola trage de o pîrghie oscilanta.The invention relates to a bending machine having all hydrostatic actuations, operating in an automatic or manual cycle, the pipes being able to be bent cold or hot, with or without a mandrel. The bending machine is formed by a bead on which is mounted a movable support which executes the main bending movement of the pipe, divided by a force cylinder, a hydraulic cylinder bringing the movable support in the initial position, supporting the pipe on a roller support sliding along a fixed frame mount. The machine is provided with a bending angle limiting device having a drum with eight or more graduated longitudinal grooves, in each channel being fixed one stop acting on the hydraulic cylinder rod to move the drum by means of an oscillating lever on an electric limiter stops the oil supply of the cast iron cylinder, and therefore the rotation movement of the movable support is provided by a counterweight which, by means of a cable mounted on a roll, draws on a swinging lever.
