Abstract
An apparatus for delivery and removal of mandrel rods for use with rolling mills. A plurality of rocking levers are arranged one behind the other in the direction of rolling and are pivotable into upper and lower positions. Free ends of the levers are provided receivers for receiving the mandrel rod. The pivot or rocking levers are two-armed angle levers which are slidably mounted in two different positions such that in the first position the receivers on the angle levers are maintained in the vertical projection through the rolling axis and in the other position are offset from such vertical projection.
Claims5
Device for the delivery and removal of mandrel rods in skew and longitudinal rolling mills between a roll stand and mandrel support with a plurality of rocking levers arranged one behind the other in the direction of rolling and which are pivotable into an upper and a lower position, on the free ends of which levers receivers are provided for receiving the mandrel rod, and which are mounted in horizontal pivot bearings extending transversely to the rolling direction and which have a pivot drive,
- characterized in that the rocking levers are two-armed angle levers forming an angle of 60.degree. to 150.degree. therebetween with a receiver mounted on one side of both arms, the pivot axes of which, approximately at the level of the rolling axis and in the horizontal transversely to the direction of rolling, are slidably mounted in two different positions, in by drive means which in a first position the receivers stand on the angle levers in the vertical projection through the rolling axis and in the other position are offset adjacent said vertical projection through the rolling axis.
