By constructing the theoretical calculation model of cutting tooth temperature rise of PDC drill bit, the temperature of cutting tooth under the action of heat-fluid-solid coupling was analyzed by numerical simulation, and by changing the drilling pressure parameter in the cutting model, the temperature rise law of the cutting tooth was obtained under the condition of different drilling pressures, so as to validate the correctness of theoretical model and simulation data. By building a coal rock drilling test platform, the drilling test of PDC drill bit under different drilling pressure parameters was carried out. The analysis results show that: with the increase of drilling pressure, the temperature of the cutting teeth of PDC drill bit increases, when the drilling pressure is increased from 1kN to 4kN, the temperature rises by 441%, and when the drilling pressure reaches 5kN, the temperature rises by 49.64%; the use of wind circulation can effectively reduce the temperature of the cutting teeth of the PDC drill bit, and the larger the wind speed, the more obvious the effect of the temperature drop of the drill bit; The error values of cutting teeth simulation temperature and theoretical temperature are within 10%, and the model provides a theoretical basis for improving the working efficiency of PDC drill bit in wind-discharged coal rock drilling.
