ABSTRACT:
A rapid thermochemical treatment automatic installation for a charge constituted by parts, intended particularly for the mechanical industry, which includes a plurality of treatment modules such as an induction preheating module, thermochemical treatment modules, a quenching module, a device for carrying out the loading and unloading of the parts stacked in columns and a transfer device of the columns of parts between the various treatment modules. The installation includes a fixed circular plate on the periphery of which are distributed various treatment modules, which are suspended beneath the lower surface of the plate, which plate is formed with openings which can be tightly closed for the introduction of the parts to be treated in the respective modules, and a mobile disc rotably and coaxially mounted above the fixed plate, the mobile disc receiving the transfer device so that the transfer device can be brought successively above the loading/unloading station and the access station to the various modules for respectively introducing in the installation a column of parts to be treated, transferring the column of parts to be treated, transferring the column successively to the various modules and extracting from the installation the column of parts after treatment.
