Abstract

629,607. Rolling-mandrel carriages. AETNASTANDARD ENGINEERING CO. Aug. 23, 1946, No. 25269. Convention date, March 9. [Class 83 (iv)] In the production of tubes by skew-rolling over a piercing-mandrel, the mandrel is carried by a support movable over a run-out table and has an intermediate support movable with the end support but at half the rate. Fig. 1 shows the parts in the position for rolling, a reduced part 14 of the mandrel being over the support 12 so that free rotation of the mandrel is not impeded. In this position a projection 31 on the support 8 is engaged by a detent 30 to resist the thrust. A cable 16 is connected to the support 8 through a turn-buckle 27, and passes to a winch 18 motor-driven at 20, thence round a fixed pulley 19 and a pulley 21 on the carriage 10 to a turn-buckle 29. A second cable 23 connects the carriages 8 and 10 and is anchored at 26. On removal of the detent and operation. of the winch the carriage 8 is run out to withdraw the mandrel through the rest 9. A bevel 15 permits the mandrel to engage the support pulley 12 without shock.
