Abstract：

In order to solve the problem of wire connection and winding for heating and temperature control elements during roll rotation, the structure of the heating and temperature control system for aluminum alloy cross wedge rolling mold was designed, and the layout of the heating and temperature control elements was designed and optimized. Then, the heating efficiency and temperature uniformity of the mold were ensured by using multi-point heating and temperature measurement method. Furthermore, an adaptive mold temperature compensation system based on PID control algorithm was developed, which automatically adjusted the heating tube power according to the set temperature control logic to control the mold temperature within the range of process requirements. Finally, based on the heating and temperature control system of mold, an aluminum alloy precision cross wedge rolling mill was developed. The aluminum alloy cross wedge rolling forgings with good dimensional consistency and high surface quality were mass-produced. The results show that the research results are feasible and can be used in the development of rotary forming process and equipment for non-ferrous metals such as aluminum alloy and titanium alloy.
