WORM AND RACK REST BAR ASSEMBLY

摘要

A rest bar assembly (40) for a guide (38) that is employed in a rolling mill (32) to direct a hot rolled product either entering or exiting from the roll pass of a roll stand. The rest bar assembly comprises a core extending transversely with respect to the mill pass line. A saddle (46) is movable along the core and is adapted to carry the guide. An adjustment mechanism serves to move the saddle along the core. The adjustment mechanism comprises a worm rack extending along a back side (42b) of the core, and a rotatable worm carried by the saddle and in meshed relationship with the worm rack.
