Abstract
In order to use functionally gradient materials to design and manufact ure hotforging die, it is necessary to illuminate the distribution and transfo r ming laws of hotforging dies temperature field, stress field and strain field i n detail under real working conditions.This paper simulated the whole working pro cess of Hotforging die of frontwheelhub of car by DEFORM2D program. The c avi ty surface layers temperature field varying process and transforming laws from fi rst working period to thermal equilibrium was illustrated. The variable paramete rs were analyzed quantitatively. The corresponding relations and differences wer e revealed for the first time. In this way, the distribution and transforming la ws of temperature field of hotforging die were comprehended more overall and c o ncretely, which is the theoretical basis for the hot forging cavity design and p reparation of functionally gradient materials.
