Abstract
The utility model discloses rolling guide fittings with a buffer adjusting mechanism, which comprises a guide casing, two supporting arms hinged by a rotating shaft and located in the left and right of the rotating shaft, and a buffer adjusting mechanism equipped in the rear end of the supporting arms. The buffer adjusting mechanism comprises a butterfly spring, a circular nut, a screw, a nut, a flat washer, a thread sleeve and a cylindrical pin. In the rolling process, especially in rough rolling and medium rolling, the material shape of the rolling workpiece is unstable. The height H of the rolling workpiece undergoes a change. When H increases, the spacing of the guide rollers also increases and the left and right supporting arms will respectively rotate around the rotating shaft. At the time being, the thread sleeve is static and the rear end of the supporting arms drives the washer to compress the butterfly spring which has a strong rigidity and a big capacity of buffer vibration absorption and can bear great load by small deformation. Thus the impact destructive power from the unstable material shape to the guide roller or even the guide is offset in the utility model, which guarantees the capability of the guide fittings and prolongs the service lift of the guide fittings.
