The self-made thin film thermocouple was used to measure the surface temperature and the internal transient temperature of the upset die. The distribution characteristics and the range of the heat affected zone were analyzed. The temperature distribution function of the die was established. The time domain of transient temperature waveform , Frequency domain characteristics and transmission law, concludes the important conclusion that the penetration depth of die forging is closely related to the harmonic frequency of thermal shock signal, and provides the analysis of thermal stress of forging die, the establishment of theory of heat intensity and the adoption of surface modification measures Some basic data and theoretical basis.
