Title: Manufacture of fine metallic ball stock
Inventor: WATANABE MOTOTSUGU
IPC: B21H1/14
Filed: 1990-02-20
Abstract: PURPOSE:To manufacture a steel ball high in out-of-roundness by accelerating a cylindrical body cut in a length a little shorter than its diameter at a high speed and making it collide repeatedly with the hard wall surface. CONSTITUTION:Several wires 1a-1b are cut at a length shorter than its diameter to form many cylindrical bodies 6. The cylindrical bodies 6 are loaded from a throw-in hole 16, lifted by a bucket conveyor 14 to a hopper 12 and thrown into the center of a rotary blade 10 through a material supply tube 13. Since the rotary blade 10 rotates at a high speed, the cylindrical bodies 6 are accelerated by the centrifugal force, blown off radially to the periphery, collide with the hard wall 8 and the corners of the cylindrical bodies are crushed by the impact. The cylindrical body colliding with the wall surface 8 flows down in the inclined tube 15 by its dead weight, is lifted again by the bucket conveyor, supplied by the hopper 12 to the rotary blade 10, accelerated again to a high speed and collides with the wall surface 8. In this way, when the cylindrical bodies 6 are circulated repeatedly, the steel balls high in out-of-roundness can be manufactured.
