Swinging strip steel guiding conveying device

Abstract

The invention relates to a rotary guidance and transport device for band steel, belonging to the technical field of guidance and transport device for flexible workpiece, in particular to the device for guiding and transporting the band steel made by continuous casting and continuous rolling to a thin slab to a coiler. The device is characterized in that: an upper pinch roll is fixedly arranged on a swing arm, while the swing arm and a lower pinch roll are fixedly arranged in a housing window; the rotary guidance device is aslant arranged in the lower right part of the upper pinch roll, a gap is arranged on the cylindrical concave arc surface for enclosing a part of the upper pinch roll, the gap moves back Alpha angles from the gap of the upper pinch roll in relation to the biting line of the band steel, far away from the biting line; and the bottom of the rotary guidance device is a surface which is inclined Beta angles around the surface in relation to a rolling line. After use, the head of the band steel avoids the gap and runs to the bottom surface of the guidance device directly and refractably, guiding smoothly. The device has the advantages of simple and reasonable structure, reliable operation, avoidance for rolling or folding the heaping steel, convenience for reducing waste product, improving operating rate, saving energy and reducing consumption; less spare parts, easy implementation and maintenance, low running cost, and ability to avoid fire accidents of the hydraulic cylinder.

Description

Technical field [0001] The invention belongs to a device for guiding and conveying flexible workpieces, in particular to a device for guiding and conveying a thin slab continuous casting and rolling strip steel to a coiler. Background technique [0002] In the compact thin slab continuous casting and rolling (CSP) production line, a pinch device is installed between the last frame and the coiler to change the running direction of the fast-moving strip steel, guide and transport it to the coiler. The currently used strip pinching device, the upper pinch roller is fixedly mounted on the swing arm, and the swing arm and the lower pinch roller are fixedly mounted in the archway; the entrance guard plate is set in front of the upper pinch roller, and the upper pinch roller is behind the upper pinch roller. The guide device, the upper switching mechanism, the switch roller, the chute plate, and the core shaft of the winding machine are connected; the entrance guard plate and the guide ...

Problems solved by technology

Due to the thinner head of the strip steel and the upturning caused by the process, the head of the strip steel is easy and often directly drills into the gap, resulting in the fault of stacking steel; On the turning surface, when the head of the strip steel touches any one of the turning surfaces, there may be a failure of folding and stacking steel, which will cause the en...
