Abstract:
An improved straightener for rolled ferrous products of the type having a framework comprising a pair of opposed shoulders which support two sets of rolls, a top set of rolls and a bottom set of rolls, a straightening path between said two sets of rolls for straightening said rolled ferrous products, characterized in that said opposed shoulders are capable of being translated horizontally between a closed, operative, position of containment and support of said rolls and an open, non-operative, position, in which said sets of rolls are removable for replacement with other sets of different rolls, the improvement comprises:(a) a respective bearing upon which each roll of said rolls is mounted, whereby said bearings are fixed to the end of stays, which are integrally fixed to said shoulders and remain in place in said shoulders when opened; (b) a container, independent of the framework, for supporting said sets of rolls in said open, non-operative, position of the shoulders; and (c) a transmission mechanism of a motor-reducer assembly with an external and a female thread to prevent rotation of the stay and permit motion to the female thread via a worm screw.
