1,163,118. Cutting by fusion. UNITED ENG. & FOUNDRY CO. 9 Dec., 1966 [9 Dec., 1965], No. 52396/65. Heading B3V. [Also in Division B8] Apparatus for severing moving workpieces B comprises a workpiece severing station 15, means 11, 12 for moving the workpiece through the station, a conveyer 17 having means 23, 24 for supporting the workpiece passing through the station and including further spaced supports 35 defining an opening in the conveyer, a carriage 29 movable with the workpiece and cutting means 38 mounted on the carriage and adapted to act through the opening. The cutting means preferably comprise an acetylene torch adapted to swing about a pivot 39 transversely of the workpiece B which may be produced in a billet rolling mill or a continuous casting machine. The workpiece is moved by pinch rollers 11, 12 driven by a motor 13 and pressed against the workpiece by cylinder 14. Carriage 29 has wheels 31, 32 running along rails and is coupled to the roller conveyer 17 by links 33. Gripper arms 41 pivoted to the carriage are actuated by a cylinder 44 to clamp on to the workpiece and hence move the carriage therewith. The clamp cylinder may be controlled by a length measuring device. After cutting, the carriage is retracted by a cylinder assembly 46 and the cut workpieces pass on to rollers 16. Alternatively the cylinder assembly 46 may be double-acting to assist the movement of the carriage during cutting, particularly when used with hot pliable workpieces. In this case pressure regulators 30a, 30b cause the carriage to move at the same speed as the workpiece. In another embodiment, Fig. 3 (not shown) the clamping device is omitted and the conveyer, which is connected to the carriage, is driven at the same speed as the workpiece. |
