Under the action of a direct current electric field, glow discharge occurs in gas in the furnace, generated nitrogen (positive) ions bombard the surface of a workpiece (cathode), and active nitrogen atoms penetrate into the workpiece while the workpiece is heated to a required nitriding treatment temperature (generally between 400 and 600 ℃), so that the hardness, wear resistance and corrosion resistance of the surface of the workpiece are improved.
At present, most of domestic and foreign universal ion nitriding furnaces adopt bell jar type structures, and a bell jar needs to be lifted up to load and unload workpieces when ion nitriding starts or finishes.

At present, the lifting and moving of the bell jar of most bell jar type ion nitriding furnaces at home and abroad are carried out by the crane in a workshop, which is very inconvenient. In addition, the height of the bell-type ion nitriding furnace is higher, a workshop building which lifts the bell by a travelling crane needs to have at least four times of the height of the furnace, the general workshop building is difficult to meet the requirement, a pit is dug on the workshop ground in order to solve the problem, the ion nitriding furnace is placed in the pit, and a workbench of the furnace is flush with the ground. At present, ion nitriding furnaces produced abroad also adopt a self-lifting mechanism, a bell jar is lifted by a hydraulic or mechanical transmission method, and then the bell jar is rotated for an angle, so that the bell jar deviates from a base of the ion nitriding furnace. The bell jar lifting device adopted abroad mostly adopts a column structure, and a lifting point is arranged at the top of the bell jar, so that the bell jar shakes in the lifting process due to higher gravity center, and the stability is poor. In addition, in order to ensure that the bell jar does not topple over when rotating, the lifting mechanism must have a larger base, and the rigidity of the root of the upright post is also required to be higher.
Therefore, the combined base of the ion nitriding furnace is provided.
