Abstract

8594. Schilling, H. April 11. Rolling tubes; rolling-mandrels.-In tuberolling mills in which the mandrel is retained in position by a pair of locking-devices, these devices are coupled together by linkage so that one is closed before the other is opened. Guide rolls 1, 2, which may also be reducing-rolls, are provided in conjunction with working rolls 3, 4, a mandrel rod 7, and mandrel and tube supports 18. The locking-devices 6, 9 are attached to pivoted counterweighted levers coupled together by a link 10, which is also connected to a lever 16 attached to a stop 15. To insert a tube between the guide-rolls 1, the hand-lever 11, which may be replaced by a foot-lever, is operated to raise the locking-bolt 6 and lower the bolt 9. The tube on engaging the stop 15 raises the bolt 9 and lowers the stop 6.
