A pin-on-plate friction and wear test device includes a high temperature heating chamber and a cooling pin. The high temperature heating chamber is fastened horizontally to the mobile base. The axis of the cooling pin is perpendicular to the upper surface of the mobile base. The electric resistance heating plate is located in the bottom closed space under the friction sample plate in the high temperature heating chamber. The electric resistance heats the fixed sample to experiment temperature. The inner layout of pin is a circling cooling channel where the cooling medium adjusts and cools the temperature of the sample. Thermocouples are separately distributed in the temperature measuring groove of the high temperature heating chamber and the temperature measuring hole of the cooling pin for real-time temperature measurement. The device can simulate the friction and wear properties of the high-strength steel plate and hot-stamping die in the differential temperature environment.
