Abstract

1,102,074. Cutting profile bars. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY I PROEKTNO KONSTRUKTORSKY INSTITUT METALLURGICHESKOGO MASHINOSTROENIA. 12 March, 1965, No. 10685/65. Heading B3W. A flying shear for cutting profile sections comprises a pair of cutter holders 8 and 9, Fig. 1, which are secured to planet pinions 7. The pinions 7 are mounted on intermeshing gears 4 and 5 by which they are carried round. Intermediate wheels 6 mesh with the planet pinions 7 and with stationary sun gears 3 concentric with the gears 4 and 5, so that the cutting blades remain parallel as the cutter holders perform an orbital motion. Attached to the cutter holders 8 and 9 by bolts 10, Fig. 6, are combination cutters comprising rectangular blades 11 and 11<SP>1</SP> which have recesses 12 and 12<SP>1</SP> to accommodate the flanges of an I-section beam, and wedge-shaped blades 14 attached to the rectangular blades 11 and 11<SP>1</SP> by bolts 13. As the cutter holders approach one another the flanges are first cut by the blades 14 and then the web is out by the blades 11 and 11<SP>1</SP>.
