[0037] As attached Figure 1 To Attachment Figure 8 As shown:

[0039] A regulating mechanism, which is arranged at the top of the support plate 23 and the fixed base 2; the regulating mechanism includes a water tank 3, which is installed on a side wall of the top of the fixed base 2, and the outermost side of the water tank 3 is fixedly connected to a water inlet end 31, and a return pipe 32 is installed on the inner side of the water inlet end 31; a water control ring 33 is installed on the outer side of the water inlet end 31, and a control module 34 is installed at a position of the water tank 3 close to the water inlet end 31, and a temperature control component is installed at the bottom and inner side of the water tank 3;

[0040] A water cooling head 37 is installed on the inner wall of the support plate 23, the water outlet end of the water cooling head 37 is connected to the water inlet end of the return pipe 32, and the water inlet end of the water cooling head 37 is connected to the water outlet provided on the surface of the water tank 3 away from the water inlet end 31;

[0041] An air injection mechanism, which is arranged on the top of the sealing outer plate 1;

[0042] The temperature control mechanism is arranged on the outer wall of the second movable arm 26. By introducing a more efficient cooling medium, such as liquid nitrogen or a special coolant, the present invention can significantly increase the cooling rate, so that the heat in the additive process can be dissipated quickly and evenly. This efficient cooling method not only shortens the cooling time, but also greatly reduces the internal stress concentration and grain coarsening of the material caused by excessive temperature gradient, thereby facilitating the formation of a finer and more uniform grain structure and improving the overall performance of the material.

[0043] The temperature control component includes a temperature control cylinder 36, which is installed on the inner wall of the water tank 3. A liquid nitrogen input pipe 35 is also installed at the bottom of the temperature control cylinder 36.

[0044] The temperature control mechanism includes a two-way pipeline 5, which is installed on the top of the water tank 3.

[0046] Embodiment 2: According to Figure 6 , Figure 7As shown, the present invention provides a layer-cooling regulated arc additive dual-phase steel preparation device, the gas injection mechanism includes a storage cylinder 4, the storage cylinder 4 is installed on the outer wall of the sealed outer plate 1, the gas outlet of the storage cylinder 4 is installed with a gas injection cylinder 41, the top of the sealed outer plate 1 is also installed with a transmission module 42, the gas outlet end of the gas injection cylinder 41 is connected with the transmission module 42, and ventilation ports 43 are opened on both sides of the top of the sealed outer plate 1.

[0048] Embodiment 3: According to Figure 8 As shown, the present invention provides a layer-cooling controlled arc additive dual-phase steel preparation system, including a circulating water system for realizing the circulation of cooling water, including a water tank 3, a return pipe 32, a water inlet pipe and a water cooling head 37;

[0049] Intelligent temperature control system, including a temperature meter, a control module 34 and a liquid nitrogen input pipe 35, for real-time monitoring of the equipment temperature and accurate control of the cooling water temperature;

[0050] The gas monitoring and control system, including the camera module 45, the gas injection port 44 and the gas detection module 46, is used to monitor the gas environment in the working area in real time and inject argon gas as needed to stabilize the welding process. The temperature of the equipment can be monitored and accurately controlled in real time through the setting of the temperature meter, and the temperature fluctuation can be controlled within a very small range. This greatly improves the temperature control accuracy of metal manufacturing, welding and other processes, and ensures the stability and consistency of product quality.

[0051] The temperature meter is a high-precision sensor that can monitor the device temperature in real time and feed back to the control module 34 to achieve accurate adjustment of the cooling efficiency.

[0052] The control module 34 can accurately control the temperature of the cooling water by adjusting the water flow rate, the amount of liquid nitrogen injection, etc. according to the temperature data fed back by the thermometer to meet the specific temperature requirements of the metal manufacturing and welding processes. The camera module 45 can capture the height information of the metal manufacturing parts and feed it back to the control module 34 to dynamically adjust the cooling rate to ensure the accuracy of temperature control.

[0053] Specifically, in actual use, the system first monitors the temperature changes in the additive process in real time through temperature sensors. These sensors are precisely placed in key parts of the additive equipment.

[0054] Dynamic cooling control strategy:

[0055] Based on real-time temperature data, the system adopts a dynamic cooling control strategy, which automatically adjusts parameters such as the flow rate, temperature or cooling time of the cooling medium according to the difference between the current temperature and the preset target temperature.

[0056] For example, when the temperature is higher than the preset value, the system will increase the flow rate of the cooling medium or reduce its temperature to speed up the cooling; conversely, when the temperature is lower than the preset value, the system will reduce the flow rate of the cooling medium or increase its temperature accordingly to avoid overcooling;

[0057] In order to implement the above control strategy, the system adopts an advanced control algorithm. The core of the algorithm is to establish a mathematical model between temperature and cooling parameters. By continuously iterating and optimizing this model, the system can gradually approach the optimal cooling control strategy.

[0058]

[0059] In this formula, K_p , K_i and K_d These are parameters that need to be tuned through experiments or simulations. They determine the weight of proportional control, integral control, and differential control in the total control output. By adjusting these parameters, the system can implement different cooling control strategies to meet the needs of different additive materials and processes.

[0060] The gas injection port 44 can monitor the gas composition in the working area in real time, especially the oxygen content and possible harmful gases, to ensure the stability and safety of the welding process;

[0061] The gas detection module 46 can control the control module 34 to inject argon into the working area according to the data of the gas detection module to create a stable inert gas environment and improve the welding quality; by integrating the gas detection module with the gas injection port, the system can monitor the gas composition of the welding area in real time and inject argon and other inert gases as needed to create a stable welding environment. This effectively prevents the occurrence of welding defects such as oxidation and pores, and significantly improves the welding quality and product reliability.

[0062] Working principle: When it is necessary to use this device, firstly, the position of the support plate 23 can be adjusted through the transverse track 22 and the connecting slide rail 21 to facilitate the material addition, and then the material addition process can be carried out through the injection head. Then, an external water source can be used to connect the two-way pipeline 5, and the two-way pipeline 5 can be used to cool the injection head through the segmented pipeline 52 and the loop heat dissipation pipe 53. When layer cooling is required, firstly, cold water is supplied to the water cooling head 37 through the water tank 3, so that the water cooling head 37 can cool the surface of the support plate 23, and the water flow can enter the inner side through the external baffle plate on the outer side of the support plate 23 to cool the material formed on the inner side. Each layer is formed. The water used for cooling will rise one layer accordingly, and then the water will flow back into the water tank 3 from the return pipe 32 to the water inlet end 31. When the temperature sensor detects that the temperature is too high, liquid nitrogen can be injected into the temperature control cylinder 36 through the liquid nitrogen input pipe 35. At this time, the water returning from the water inlet end 31 will be quickly cooled by liquid nitrogen, which is convenient for efficient cooling when it flows back next time. When there is less inert gas in the equipment, the gas injection port 44 at the upper end will detect it, and then the gas injection port 44 will allow the storage cylinder 4 to inject gas into the gas detection module 46 through the gas injection cylinder 41 through the transmission module 42. The gas is connected from the gas detection module 46 to the equipment to stabilize the welding process.
