987,171. Shearing. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 14, 1961 [April 15, 1960], No. 13518/61. Heading B3W. [Also in Division G6] A machine for cutting in.half a storage casing E containing irradiated fuel elements comprises two similar assemblies B, C (assembly B being shown in elevation and assembly C in section) each assembly having a clamp 3 operated by a jack 4 for gripping an end of the casing, a cutting head A being interposed between the assemblies B, C. Each clamp holds the casing E within a guide tube 2 pivoted about an axis O 1 on a carriage 5, a traction force being applied to the casing by jacks 8 acting on the carriages through rods 17. The carriages 5 are guided for horizontal movement by the horizontal portions 6a of slots 6 provided in fixed checks 7 and are pivoted about axes O 2 in the slots so that after the casing has been cut the jacks 8 may move the carriages and the inclined slot portions 6b cause the tubes 2 to be rotated into the vertical position (shown in chain-lines) whereby the fuel elements are discharged. The cutting head A comprises a cutting wheel 9 and a counter-roller 10 which are caused to rotate around the periphery of the casing by an electric motor operating through bevel gearing (Fig. 2, not shown). The wheel 9 and roller 10 are applied against the casing by a spring and may be moved in the opposite direction to remove the cutting action by a jack 11 acting through levers (Fig. 4, not shown). The machine is intended for use under water and be remotely controlled (Fig. 6, not shown). |
