Abstract
A multiple section bars straightening/cutting system in a bar rolling line comprises a multiple section bars straightening apparatus, an inlet side introduction pinch roller, a multiple traveling section bars cutting apparatus and a rear surface tilting table having an outlet side introduction pinch roller. The multiple traveling section bars cutting apparatus includes a fixed blade and a moving blade each having a plurality of calipers formed in accordance with the cross-sectional shapes of the section bars. The rear tilting table tilts in the direction in which the blades of the multiple traveling section bars cutting apparatus move in synchronism with the movement of the blades.
Claims12
A multiple section bars straightening/cutting system in a rolling mill, comprising:
- a multiple strands straightening apparatus for straightening the multiple section bars;
- an inlet side introduction pinch roller disposed downstream of the multiple strands straightening apparatus for clamping the section bars straightened by the multiple strands straightening apparatus and introducing the straightened section bars downstream;
- a multiple traveling section bars cutting apparatus disposed downstream of the inlet side introduction pinch roller and having fixed blades and moving blades each including a plurality of calipers formed in accordance with cross-sectional shapes of the section bars for cutting the section bars while the section bars travel by obliquely moving the moving blades with respect to the section bars;
- and
- a rear surface tilting table disposed downstream of the multiple traveling section bars cutting apparatus, said rear surface tilting table having an outlet side introduction pinch roller for clamping the section bars, and tilting in a direction in which the blades are moved in synchronism with the movement of the blades.
