[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] Example 1: To address the problem of lengthy development cycles in traditional material and process exploration, specifically, during the research and development of new materials or processes, it is necessary to test the feasibility of various materials and processes one by one. This process is not only time-consuming but also costly, which in turn leads to extended process development cycles and increased trial and error costs.

[0028] The intelligent diffusion welding furnace includes a housing 1, a heating mechanism 2, and an installation mechanism 3. The heating mechanism 2 is located on the top of the housing 1. The heating mechanism 2 includes a furnace body 21, a furnace chamber 22, an abutment part 23, a pressing part 24, and a detection part 25. The furnace body 21 is located on the side of the housing 1 and is used to place the parts to be processed. The furnace chamber 22 is located on the inside of the furnace body 21. The abutment part 23 is vertically located inside the housing 1 and extends through to the inside of the furnace body 21, and is used to place the parts to be processed. The pressing part 24 is vertically slidably located on the top of the furnace body 21 and is used to abut the parts to be processed against the top of the abutment part 23. The detection part 25 is located on the side of the furnace body 21 and is used to detect the temperature inside the furnace body 21. The installation mechanism 3 is located inside the housing 1.

[0029] In this embodiment, a rotatable sealing door is hinged to the side of the furnace body 21. The mating surface between the sealing door and the furnace body 21 is provided with a high-temperature resistant silicone rubber sealing gasket. The operator can open the sealing door to accurately place the component to be heated on the upper end face of the abutment part 23. After placement, the sealing door is closed. The high-temperature resistant silicone rubber sealing gasket fills the gap between the mating surfaces through elastic deformation, ensuring the sealing performance of the furnace chamber 22 and providing a foundation for the stable progress of the welding process.

[0030] A pressure sensor is installed at the output end of the pressing section 24. A controller is integrated inside the housing 1, which is electrically connected to the servo motor, pressure sensor, and detection unit 25 to receive signals and issue control commands. Once the part to be welded is in place, the controller sends a command to drive the pressing section 24 to descend vertically until it contacts the upper surface of the part. At this time, the pressure sensor collects pressing force data in real time and feeds it back to the controller. The controller compares the collected pressure value with a preset threshold, such as 5-20 MPa. When the preset pressure is reached, the controller immediately stops the pressing section 24, completing the precise fixing of the upper and lower ends of the part to be welded.

[0031] The detection unit 25 is a thermocouple temperature sensor, which is installed in a mounting bracket on the side wall of the furnace body 21. The detection end extends into the furnace chamber 22, and its signal output end is electrically connected to the signal input end of the controller via a shielded cable, enabling the real-time monitoring of the temperature data inside the furnace chamber 22 to be transmitted to the controller. A touch screen display is embedded on the side of the housing 1. This display is electrically connected to the signal output end of the controller and is used to visually display real-time operating data such as temperature, pressing pressure, and vacuum level inside the furnace chamber 22.

[0032] The inner wall of the furnace body 21 is also equipped with a heating unit, which is electrically connected to the controller and is used to receive controller commands to realize temperature regulation in the furnace chamber 22, adapting to a process temperature range of 500-1200℃.

[0033] The specific implementation process of process debugging and simulation based on the above structure is as follows:

[0034] S1: Parameter input stage: The user inputs the material information of the part to be processed, such as titanium alloy and high temperature alloy, as well as the preset process requirements through the touch screen, including temperature range of 500-1200℃, pressure range of 5-20MPa, and holding time of 10-120min. The screen transmits the input information to the controller in real time.

[0035] S2: Simulation and deduction stage: The controller has a built-in material welding process model trained on big data. This model has a pre-stored library of welding characteristic parameters for different materials. After receiving the input parameters, it simulates and deduces the input parameters by matching the adaptation relationship between material characteristics and process parameters. Through algorithm optimization, it generates 3-5 sets of candidate process schemes, including detailed parameters such as heating rate, pressure holding time, and temperature stability range during the holding stage, and feeds them back to the display screen for the user to select.

[0036] S3: Scheme Execution Stage: After the user selects the target scheme through the display screen, the controller sends control commands to the heating unit, driving pressing part 24 and rotary driver 291 of the furnace body 21 to start trial production and debugging;

[0037] S4: Real-time Control Phase: During commissioning, thermocouple temperature sensors continuously collect real-time temperature data within the furnace 22, and pressure sensors simultaneously collect pressing pressure data. Both are transmitted to the controller in real time. The controller compares the real-time data with the preset parameters of the candidate scheme. If a deviation occurs, such as a temperature deviation exceeding ±5℃ or a pressure deviation exceeding ±0.5MPa, an adjustment command is immediately issued: for temperature deviations, the power of the heating unit is adjusted; for pressure deviations, the displacement of the pressing section 24 is controlled and fine-tuned to ensure that the process parameters remain stable within the preset range.

[0038] S5: Process Consolidation Stage: When three consecutive batches of workpieces pass quality inspection during the debugging process, and the quality inspection standards for workpieces are: the tensile strength of the welded joint is not less than 90% of the strength of the base material, and the flatness error of the joint does not exceed ±0.1mm, the controller automatically stores the set of process parameters as a standard process plan. Users can export or directly call it for mass production via the display screen. At the same time, all debugging data, including parameter adjustment records and quality inspection results, are automatically recorded and archived by the controller and can be exported via the network interface to achieve full traceability of the process.

[0039] See Figures 2-3 The heating mechanism 2 also includes a connecting guide rail 26, a sliding part 27, and a linear cylinder 28. The connecting guide rail 26 is located inside the housing 1 and above the furnace body 21. The sliding part 27 is vertically slidably disposed on the outside of the connecting guide rail 26, and the end face of the sliding part 27 is connected to the top of the pressing part 24. The linear cylinder 28 is disposed beside the sliding part 27, and the output end of the linear cylinder 28 is connected to the pressing part 24. When the linear cylinder 28 is activated, it can drive the abutment part 23 to move.

[0040] In this embodiment, a displacement sensor is provided beside the sliding part 27. This displacement sensor is electrically connected to the controller and is used to measure the position and movement distance of the sliding part 27 on the connecting guide rail 26. The displacement sensor can also transmit signals to the controller, which can limit the movement position and dwell distance of the sliding part 27 on the connecting guide rail 26 based on the signals. Furthermore, in this embodiment, the controller is connected to the linear cylinder 28 and is used to control the fine-tuning, lifting, and lowering actions of the linear cylinder 28. Real-time feedback is provided on the positioning status of the sliding part 27 and the pressing part 24 of the workpiece to be processed, ensuring processing accuracy.

[0041] See Figures 2-4 The heating mechanism 2 also includes a vacuum pump 29, a rotary driver 291, and a vacuum transmitter 292; the vacuum pump 29 is mounted on the housing 1; the rotary driver 291 is mounted beside the vacuum pump 29, and the output end of the rotary driver 291 is connected to the input end of the vacuum pump 29; the vacuum transmitter 292 is mounted on top of the vacuum pump 29.

[0042] To ensure uniform heating and maintain a stable vacuum environment within the furnace 22, this embodiment employs a combination of a vacuum pump 29 and a rotary actuator 291. The rotary actuator 291 is preferably a servo motor, connected to a controller, which in turn is connected to a display screen. The display screen allows control of the rotary actuator 291's rotation speed and number of revolutions. The rotary actuator 291 drives the vacuum pump 29 to extract air from the furnace 22, creating a vacuum environment. A vacuum transmitter 292 monitors and feeds back vacuum data to the controller in real time, ensuring the vacuum level within the furnace 22 remains stable within a set range, such as ≤10 Pa, providing a stable environment for material process debugging.

[0043] See Figure 5 The heating mechanism 2 also includes an air pressure connection pipe 293; the air pressure pipe is located on the side of the furnace body 21, and one end of the air pressure pipe is connected to the furnace body 21, and the other end of the air pressure pipe is connected to the vacuum transmitter 292.

[0044] When vacuum pump 29 is operating, pneumatic connection pipe 293 assists in extracting air from furnace 22 and provides a stable pressure transmission channel for vacuum transmitter 292, ensuring the accuracy of vacuum monitoring. Simultaneously, vacuum transmitter 292 transmits monitoring data to the controller, ultimately displaying the vacuum level within furnace 22 on a screen, ensuring the stability and reliability of the gas path system during material process debugging.

[0045] In Example 2, to address the issue that during the installation of the vacuum pump 29, the operator needs to precisely position the mounting bracket 31 to the top of the circular limiting part 32. This requires the operator to ensure that the mounting bracket 31 is strictly aligned with the vacuum pump 29 and accurately placed within the central area enclosed by the four circular limiting parts 32, resulting in a relatively slow installation speed for the vacuum pump 29.

[0046] See Figure 4 The mounting mechanism 3 includes a mounting frame 31, a circular limiting part 32, a first limiting part 33, and a second limiting part 34. The mounting frame 31 is mounted on the bottom of the vacuum pump 29. There are multiple circular limiting parts 32, which are respectively located on the bottom of the housing 1, and all of the multiple circular limiting parts 32 are located on the bottom of the mounting frame 31. The first limiting part 33 is located on the top of the circular limiting part 32. The second limiting part 34 is rotatably located on the side of the housing 1. The second limiting part 34 has a cuboid structure and is made of a rigid material.

[0047] First, the operator places the vacuum pump 29 and the mounting bracket 31 on top of the circular limiting part 32, and then makes the mounting bracket 31 abut against the first limiting part 33 and the second limiting part 34. At this time, the mounting bracket 31 and the vacuum pump 29 can be abutted by the first limiting part 33 and the second limiting part 34. After abutting, the mounting bracket 31 and the vacuum pump 29 will automatically be in the middle position of the four circular limiting parts 32, so that the operator can quickly install the vacuum pump 29.

[0048] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
