AI Technical Summary

Technical Problem

The existing vacuum annealing furnaces have problems of uneven heat and low cooling efficiency during heating and cooling, and the heating components are prone to corrosion after long-term use, which affects the annealing effect.

Method used

An annealing cooling device is designed, including a furnace body, heating assembly and cooling assembly. The rotating motor drives the guide rail and the carrier rack to rotate forward and reversely to ensure that the heating plate and the parts are in full contact; during cooling, the annular pipe and the carrier rack are coordinated. Reciprocating movements improve cooling efficiency, and realize airflow circulation and coolant circulation through fans and liquid-cooled radiators to clean up dirt on heating components.

Benefits of technology

Improves the uniformity of parts during heating and cooling, improves the annealing effect, extends the service life of heating parts, and improves the cooling efficiency.
