ギア、シャフト、リングおよび類似のワークピースの真空浸炭および焼入れのための多チャンバ炉

Japanese Patent JP6723751

B2

Multi-chamber furnace for vacuum carburizing and quenching of gears, shafts, rings and similar components has at least two (preferably three) process chambers connected in parallel, with a continuous feeding mechanism for individual workpieces. Those chambers - the first one being a heating chamber (2a), the second being a carburizing chamber (2b) and the third one diffusion chamber (2c) - are configured advantageously in a vertical arrangement, placed in a shared vacuum space with gas-tight division, whereas at the ends of each chamber (2a, 2b, 2c) there are incorporated heating chambers with thermal insulation, with a graphite heating system and a stepping feeding mechanism (13a, 13b, 13c) incorporated in the core for the purpose of continuous feeding of individual workpieces. At the ends of those chambers (2a, 2b, 2c) the construction incorporates transport chambers (5 and 6) featuring loading and unloading systems X-Y (7a and 7b) enabling cooperation with individual process chambers through thermal and gas-tight doors installed in chamber ends, while external access to the transport chambers is ensured through loading and unloading locks (8 and 14).
