This invention discloses an isothermal forging process and equipment for ultra-high power-to-weight ratio UAV pistons, relating to the field of UAV piston forging technology. The process includes obtaining the target forging temperature, acquiring the temperature values ​​detected by temperature sensors on both sides of each set of flow channels in real time through a control system, acquiring the actual temperature of the die cavity before and after forging using a thermal infrared sensor, and predicting the predicted temperature within each part of the die cavity using the temperature values ​​detected by the temperature sensors on both sides of each set of flow channels and a preset die cavity temperature prediction model. This invention, through the cooperation between the isothermal forging die, cooling flow channels, and control system, while maintaining the total flow rate of the set at no less than the current total flow rate, superimposes a fixed pulse step value, forcing the temperatures at the inlet and outlet ends to approach each other, thus avoiding localized temperature differences and improving the forging quality of ultra-high power-to-weight ratio UAV pistons.

The invention discloses a temperature adjusting device, semiconductor process equipment and a temperature adjusting method, and belongs to the technical field of semiconductor processing. The temperature adjusting device is used for adjusting the temperature of the wafer, the temperature adjusting device comprises a shading assembly, a temperature detection assembly and a driving assembly, and the shading assembly is movably arranged between the heating source and the wafer and is used for shielding the wafer; the temperature detection element is used for detecting the temperature of the central area and the edge area of the wafer; the driving assembly is connected with the shading assembly and used for driving the shading assembly to act according to a detection signal of the temperature detection assembly so as to adjust the shading area of the shading assembly on at least one of the center area and the edge area. In the scheme, the shielding area of the shading assembly on at least one of the central area and the edge area is adjusted according to the temperature difference, detected by the temperature detection assembly, of the central area and the edge area of the wafer, it can be guaranteed that the temperatures of the central area and the edge area are the same, and therefore the wafer is prevented from deforming or jumping up from the supporting ring.
