Abstract
Hot forging die is one of the important tools for machining. Because of its bad working environment, it is prone to lose its effect. Repairing the retired hot forging die can reduce the production cost and prolong the service life of the die, which has good economic benefits. In view of the complexity and uncertainty of hot forging die repair process, and the complexity and uncertainty of hot forging die repair process, this paper constructed the evaluation indexes of technical feasibility, economic feasibility, environmental feasibility, life-span feasibility and time-effectiveness feasibility, and comprehensively uses AHP and matter-element extension model to evaluate the repairability of retired hot forging dies. The rationality of this method was verified by the repairability evaluation of the hot forging die of a retired automobile steering knuckle.
