Full-automatic nitriding treatment system for surface treatment of large mold

Abstract

The invention discloses a full-automatic nitriding treatment system for surface treatment of a large mold. The full-automatic nitriding treatment system comprises a containing assembly, a bearing assembly, a heating assembly, a vacuumizing assembly and a nitrogen charging assembly, wherein the containing assembly comprises a vacuum tank body, a first tank cover and a plurality of supporting pieces, and the bearing assembly comprises a rail, a moving piece, a second tank cover and a bearing piece; the heating assembly comprises a plurality of connecting pieces and a plurality of heating pipes, and the vacuumizing assembly comprises a vacuum pump and an extraction pipe; and the nitrogen charging assembly comprises a nitrogen pump and a gas outlet pipe. According to the full-automatic nitriding treatment system, a vacuum nitriding space is provided through the containing assembly; the containing assembly can be conveniently sealed through the bearing assembly, and the large mold to be nitrided can be simply and conveniently placed; the heating assembly is used for heating and providing energy required by nitriding; the vacuumizing assembly is used for vacuumizing in advance, so that subsequent nitriding is facilitated; and nitrogen is charged through the nitrogen charging assembly, and thus a nitrogen element source required by nitriding is provided.

Description

technical field [0001] The invention relates to the technical field of rotary sails, in particular to a fully automatic nitriding treatment system for surface treatment of large molds. Background technique [0002] Molds are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, die casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. With the development of industrial technology, large molds, as a kind of molds, are more and more widely used in industrial production. [0003] After the production of large-scale molds, nitriding treatment is required. The nitrogen ions generated after the ionization of nitrogen-containing gas are bombarded on the surface of the parts to be heated and nitrided to obtain a mold with a nitriding layer on the surface, which significantly improves the hardness of the mold surface and makes it have High wear resistance, fatigue strength, corro...
