Double annealing mechanism

Abstract

The invention discloses a double annealing mechanism. The double annealing mechanism comprises a fixed box and annealing power sources. The number of the annealing power sources is two. The bottoms ofthe annealing power sources are fixedly connected with the top of the fixed box through supporting legs. The two sides of the back face of the inner wall of the fixed box are fixedly connected with heating devices. The two sides of the bottom of the inner wall of the fixed box are fixedly connected with water boxes. The positions, located at the tops of the water boxes, of the two sides of the back face of the inner wall of the fixed box are fixedly connected with water cooling circulating devices. The invention relates to the technical field of the metal heat treatment process. According tothe double annealing mechanism, the annealing effect of a copper wire can be greatly improved through double heating and double annealing treatment of the copper wire; a temperature sensor is arranged, the heating temperature can be controlled, the temperature of the copper wire is increased slowly, and the problems that due to sudden increase of the temperature, the surface of the copper wire isrough, and toughness is poor are avoided; and meanwhile, continuous operation is achieved, contact of the copper wire and air is avoided, the oxidation phenomenon is avoided, and the annealing qualityof the copper wire is improved.

Description

technical field [0001] The invention relates to the technical field of metal heat treatment technology, in particular to a secondary annealing mechanism. Background technique [0002] Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness, improve machinability, reduce residual stress, stabilize size, and reduce deformation and cracks. Tendency to refine the grain, adjust the structure, and eliminate the defects of the structure. To be precise, annealing is a heat treatment process for materials, including metal materials and non-metal materials, and the annealing purpose of new materials is also similar to that of traditional metal annealing. [0003] The existing copper wire annealing treatment is generally directly put into water or cooling liquid for annealing and cooling. There is no heating link before...
