Vertical-rolling mill

The utility model relates to a steel rolling machine with a vertical roller. A vertical-roller driving mechanism is composed of synchronous gear boxes, a spline input shaft and an output shaft; the two synchronous gear boxes are racked and held on a cross beam of a machine frame with four posts, and are positioned on an upper cross beam by regulating threaded rods; a spline shaft which is horizontally arranged penetrates through the two synchronous gear boxes by being used as the output shaft of the two synchronous gear boxes, and one end of the spline shaft is connected with a power source. A vertical-roller lifting mechanism is composed of lifting threaded rods and a cushion iron, the four lifting threaded rods are vertically racked and held on four main posts, and the lower ends of the four lifting threaded rods are connected with an upper supporting beam of a vertical roller; the cushion iron is arranged on the lower part of a lower supporting beam, and a pressing iron is arranged between the upper supporting beam and the lower supporting frame. By the adoption of the technical proposal of the utility model, the steel rolling machine with a vertical roller has the advantages of the simplification of structure, more reasonable composition, convenient operation and maintenance, lower processing requirement to equipment, and greatly reduction of the cost of the equipment.
