摘要:
A handling machine for handling rails, arranged in line immediately downstream of a rolling plant, which allows an optimal clamping of the rail along its longitudinal extension, thus effectively withstanding the deflection and its variations, while allowing a longitudinal movement of the rail caused by thermal shrinkage, thus avoiding damages both to the external surface of the rail and to the handlers. A process of handling the rail is also described, which optimizes moving, positioning along a roller table and maintaining the rail substantially rectilinear during the thermal treatment to which it is subjected.

A handling machine for rails, arranged in line and immediately downstream of a rolling plant, which allows both to easily handle the rail for transferring it from the roller table to the thermal treatment zone, and to ensure an optimal gripping of the rail along its longitudinal extension, thus effectively contrasting its bending and variations while allowing a longitudinal movement of the rail caused by thermal shrinkage, thus avoiding damages both to the external surface of the rail and to the handlers. A rail handling process is also described, which optimizes moving, positioning along a roller table and maintaining the rail substantially rectilinear during the thermal treatment to which it is subjected.

A simple, robust and rationally operable device for tilting rolled stock comprises a tilting head comprising a gripping device for the rolled stock, which defines a tilting axis, and a first drive for rotating the tilting head about a tilting head axis extending parallel to the tilting axis to adjust the tilting head in respective tilted positions. A lifting device supports the tilting head, and a second drive is arranged to raise and lower the lifting device to adjust the lifting device in respective lifting positions. A carriage supports the lifting device, and a third drive is arranged to displace the carriage transversely to the tilting axis to adjust the carriage in respective transverse positions. A numerical control is connected to the first, second and third drives and is arranged to receive control signal components respectively corresponding to the respective tilted, lifting and transverse positions to control the drives in response thereto to adjust the tilting of the rolled stock.

A portable device is provided for turning billets supported on stands for inspection. The device has a frame, a crank arm mounted in the frame for movement through a quadrant by a hydraulic cylinder, a billet engaging bracket on the end of the crank, and further billet engaging frames extending from the frame to either side of the crank so as to sustain on adjacent billets the reaction from the crank arms as its bracket turns a billet. The turning action is improved by inclusion of a lost motion link between the crank arm and the cylinder. To make the device easier and lighter to handle, it is spring suspended from a movable stand which also supports a power pack for operating the cylinder.

Apparatus for turning an elongated billet on a mill table about its longitudinal axis without displacing it laterally of the table comprises a U-shaped billet rotating head mounted on a car movable below the mill table transversely thereof. Means are provided for simultaneously rotating the billet-turning head and moving the car in the direction opposite to the direction of rotation of the billet rotating head.
摘要:
Manipulator for a rolling mill and particularly for a rolling mill for ingots or billets of steel. The manipulator comprises a pusher for pressing the ingot or billet through the roll-nip of the rolls at the beginning of rolling, and grab means for manipulating the ingot or billet during rolling when the pusher is raised up and the grab means can reach the ingot or billet.
