AUTOMATIC MACHINE FOR QUENCHING BOLT HEADS AT HF-CURRENT HEATING OF THEM Russian patent published in 2005 - IPC

FIELD: heat treatment of metals.

SUBSTANCE: automatic machine includes hopper type charging device provided with tilter; pin type conveyer, accumulator, drive unit, feeding disc with limiting bracket, inductor, quenching tank. Feeding disc is built-up one; it has outer ring with radial grooves and inner disc. Discs are mounted in lateral surfaces of grooves. Outer ring and inner disc have rotation drive unit for rotating them in the same direction with different angular velocity. Limiting bracket is in the form of flexible metallic belt embracing outer ring in heating zone for forcing rods of bolts to inner disc. Said bracket includes set of weights for adjusting forcing effort.

EFFECT: possibility for automating operation of charging hopper with bolts, enhanced operational reliability of automatic machine, uniform hardenability and high-quality quenching of bolt heads.
