Full-automatic large-size rotary hearth furnace carburizing and quenching production line device

Abstract

The invention discloses a full-automatic large-size rotary hearth furnace carburizing and quenching production device in the technical field of machinery. The full-automatic large-size rotary hearth furnace carburizing and quenching production device comprises an automatic rotary lifting storage platform and automatic feeding manipulator. The top of the automatic rotary lifting storage platform and automatic feeding manipulator is provided with a feeding and discharging manipulator track. An inner cavity of a rotary hearth high-temperature carburizing furnace is provided with an equant saw-toothed supporting beam. According to a full-automatic large-size rotary hearth furnace carburizing and quenching production process method, operation of all the processes is automatically completed, and a workshop travelling crane does not need to be used for transferring materials; quenching can be conducted on the same production line by choosing different media according to different heat treatment requirements; and on the same production line, carburizing heat treatment, hardening and tempering heat treatment, annealing heat treatment and normalizing heat treatment can be competed through combination of different unit devices, so that a multifunctional production line in a real sense is achieved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a fully automatic large-scale rotary hearth furnace carburizing and quenching production device. Background technique [0002] As we all know, well-type furnaces, pit furnaces or trolley furnaces with high energy consumption are used for pre-heat treatment and surface chemical strengthening heat treatment of large-scale ring and disk mechanical parts at home and abroad. The large-scale mentioned here refers to the fact that a single furnace charge is no less than 5 tons, and the second means that the diameter of a single heat-treated ring or disc part is not less than 1000mm. The heat treatment of parts using the above-mentioned furnace-type production line requires special heat-resistant tooling and the lifting equipment in the workshop to complete. Among them, every time the loading and unloading operation of the trolley furnace is completed, the red-hot furnace bottom (tr...
