[Class 83 (iv).] Billet piercing; forging machines: dies; mandrels.-Seamless boilers &c. are forged from a pierced billet by means of internal expanding tools 9, 10 acting in combination with the hammer 7 and anvil 8 of a press or hammer. The two-part oval expanding tools 10 are held in position by stays 11 and are expanded by a wedge member 9 on the ram 5 oi a hydraulic cylinder 1 mounted on a carriage 2 slidable along ways 3 on a carriage 4 ; stays 11 and ram 5 are hollow for the passage of cooling fluid to the wedge and tools 9, 10. Billet 20 is supported on rollers 19 journalled on members 21 formed with hydraulic cylinders for rams 22 mounted on tables 4, 18 ; members 21 also support cylinders 23 and rams 24 operating racks 25 and pinions 26 on the axles 27 of the rollers 19 for rotating the latter. Long side bolts 12 extending from the cylinder 1 pass through a crosshead 14 forming an abutment for the billet, and hydraulic means are provided for moving the tables 4, 18 on the press entablature separately or together. In operation, the tools 10 are expanded within the billet by ram 5 and the billet is lowered on to the anvil 8 by releasing the supporting rams 22 and squeezed by operating hammer 7. Tools 10 are then released, billet raised off anvil by rams 22, and slightly rotated by rams 24, the internal expansion and external squeezing being then repeated, and so round the whole circumference and then along the whole length of the billet.
