摘要：

为了解决轧辊转动时加热控温元件的导线连接和绕动问题，对铝合金楔横轧模具加热控温系统进行了结构设计，并对加热控温元件的布局进行了设计优化，采用多点式加热测温方式保证了模具的加热效率和温度均匀性。开发了基于PID控制算法的功率自适应模具温度补偿系统，可根据设定的控温逻辑自动调节加热棒功率，将模具温度控制在工艺要求范围内。基于该模具加热控温系统开发了铝合金精密楔横轧机，批量生产了尺寸一致性好、表面质量高的铝合金楔横轧锻件，表明该项研究成果切实可行，可用于铝合金、钛合金等有色金属的回转成形工艺及设备的开发。

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.
