Abstract: 1505951 Flying shears OFFICINE MECCANICHE DANIELI ET C SpA 2 Jan 1976 [13 Jan 1975] 00078/76 Heading B3W A flying shear for cutting moving, particularly continuously cast, billets comprises a carriage 10 movable along rails 30 by an hydraulic actuator 40 and connected by a parallelogram linkage 11-13 to a frame 14 carrying an upper blade 17 and integral with the cylinder 27 of an hydraulic actuator 22. Integral with the piston 21 of the actuator is a frame 15 carrying the lower blade 19 and in the position of rest of the shear (Fig. 2, not shown) the frame 15 is supported by the carriage 10 by means of lugs 35 which rest on brackets (36) on the carriage 10. A billet (34), Fig. 3 (not shown), is fed to, and removed from, the shear by roller tables (37) and is supported during shearing by a table 32 of the carriage 10. Means (not shown) sensing the thickness of the billet control the actuator 22 so that the blade 17 is stopped on the return stroke at a position just above the billet. In use, supply of oil to the chamber 23 first lowers the frame 14 until the blade 17 contacts the billet, and the hydraulic actuator 40 moves the carriage with the billet. Then the frame 15 is lifted off the brackets (36) and the billet is severed. Once the frame 15 has left the brackets (36) the frames are guided during vertical movements by the parallelogram linkage 11- 13. After shearing, oil is supplied to chamber 24 which returns the frames to their rest position. Other guides may replace the parallel linkage and the frames may move along parallel axes, rather than coaxially as shown. The direction of movement of the frames may be horizontal or at an angle between horizontal and vertical.

Electrolyte is supplied and removed by pipes 44 and 46 respectively and may be circulated by a pump P. The apparatus may be constructed to treat only one edge of the metal. In edge conditioning aluminium to remove burrs or protuberances, the electrodes 20 may be of graphite or lead, the electrolyte may be sulphuric acid 10-15% strength by weight at a temperature between 100‹ and 130‹ F. and the current density on the exposed edge portions may be 1000 to 5000 A/ft.<SP>2</SP>. Rounded edges are obtained. The edge conditioning may be followed by anodising, the electrolysing conditions being essentially the same as before except that the temperature is kept around 70‹ to 80‹ F. to permit establishment of an oxide layer on the edges. Specification 894,394 is referred to.
