[0002] There are various processes for preparing high-temperature alloy powders. Currently used high-temperature alloy powder consolidation processes include: vacuum hot pressing, hot isostatic pressing, hot extrusion, and isothermal forging. Among these, hot isostatic pressing and hot extrusion are the most widely used.

[0003] However, some equipment materials contain multiple metal structures. For example, some turbine disk metal powder materials contain elements such as Cr, Ti, and Al. Furthermore, elements like Al and Ti readily react with oxygen at high temperatures, making conventional direct sintering processes unsuitable for forming high-temperature alloy powders. Therefore, to obtain dense ingots, a high-temperature, high-pressure, and vacuum-sealed gold powder forging forming device is needed. Summary of the Invention

[0010] Preferably, the filter box is fixedly connected with filter media and filter plate. The filter media is placed on the side of the filter plate near the round tube.

The two top rods are respectively located on both sides of the electric heating structure.

[0013] A method for vacuum powder forging of a turbine disk includes the following steps: Step 1: The electrically connected hot pressing forming structure is moved down by the operation panel, and the hot pressing forming structure drives the sliding door to seal the inside of the machine body;

[0014] Step 2: The operation panel controls the vacuum component to work, bringing the inside of the machine closer to a vacuum environment.

[0019] Step 7: Control the thermoforming structure with electrical connections to fully reset via the operation panel, and complete the turbine disk powder material processing.

[0020] This invention provides a vacuum powder forging equipment and forging method for turbine disks, which have the following beneficial effects:

[0021] 1. The turbine disk vacuum powder forging equipment and forging method uses a vacuum pump to extract air from the machine body, bringing the inside of the machine body closer to a vacuum environment. This avoids oxidation reactions of the turbine disk powder material during high-temperature forging and also reduces physicochemical reactions between the turbine disk powder material and trace elements in the air during high-temperature forging. After the vacuum environment is formed inside the machine body, the inert gas extracted by the vacuum pump is delivered to the machine body through a solenoid valve. The air pressure inside the machine body is adjusted to the air pressure value required for the hot pressing of the turbine disk powder material through the air supply component. This avoids reactions between oxygen, metal particles, and special gases in the air during the hot pressing of the turbine disk powder material, while ensuring that the powder material is hot pressed under appropriate air pressure.

[0022] 2. This turbine disk vacuum powder forging equipment and forging method utilizes air filtered by a filter box, which is then pumped into the machine body via an open solenoid valve, restoring the internal air pressure. Simultaneously, the operating vacuum pump draws gas through the inlet pipe, exhaust three-way valve, guide pipe, gas collection pipe, and sliding door. This gas is then discharged through the gap between the bottom of the sliding door and the machine body, collecting and discharging the high-temperature gas from inside the machine body, thus reducing environmental impact. Through the cooperation of the extraction and supply components, a controllable gas circulation structure is formed inside the machine body after the hot pressing forming process is completed, centrally discharging the high-temperature waste gas generated during the hot pressing of the turbine disk powder material.

[0037] This invention provides a turbine disk vacuum powder forging equipment and forging method.

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 The device includes a main body 1, an operation screen 2, and a sliding door 3. The main body 1 has a hot-pressing molding structure inside, which includes two sets of camera components. The camera components capture the powder molding process when the sliding door 3 is not open. The top of the main body 1 is equipped with an air extraction component, which includes a butterfly valve 17, an exhaust three-way valve 18, a pressure sensor 20, an air guide pipe 21, an air collection pipe 22, and a vacuum pump 23.

[0039] Vacuum pump 23, pressure sensor 20, exhaust three-way valve 18, and butterfly valve 17 work together to provide a vacuum environment for the hot-pressed forging powder inside the machine body 1. The normally open end of exhaust three-way valve 18 is fixedly connected to a vertical pipe. A pressure sensor 20 is fixedly connected to one side of the vertical pipe. The pressure sensor 20 is electrically connected to the operation panel 2, which is fixedly connected to one side of the machine body 1. A telescopic pipe 19 is fixedly connected between the bottom of the vertical pipe and the outlet end of butterfly valve 17. Butterfly valve 17 is fixedly connected to the front top of the machine body 1. A gas guide pipe 21 is fixedly connected between the gas collecting pipe 22 and the normally closed end of exhaust three-way valve 18. An intake pipe 24 is fixedly connected between exhaust three-way valve 18 and the intake end of vacuum pump 23. The intake pipe 24 is L-shaped. When butterfly valve 17 is opened, vacuum pump 23 draws gas from inside telescopic pipe 19 through intake pipe 24, exhaust three-way valve 18, and the fixed vertical pipe of exhaust three-way valve 18. Telescopic pipe 19 is connected to the inside of machine body 1 through butterfly valve 17. Therefore, when the interior of the machine body 1 is sealed by the sliding door 3, the vacuum pump 23 draws gas from the interior of the machine body 1 through the intake pipe 24, the exhaust three-way valve 18, the telescopic pipe 19, and the butterfly valve 17, so that the interior of the machine body 1 approaches the vacuum environment.

[0040] Furthermore, the gas collection pipe 22 fixed to the sliding door 3 is fixed to the exhaust three-way valve 18 through the gas guide pipe 21, and the exhaust three-way valve 18 is fixed to the vacuum pump 23 through the air intake pipe 24. Therefore, the exhaust three-way valve 18, the vacuum pump 23 and the sliding door 3 move up and down synchronously. So, the installation of the telescopic pipe 19 that can perform telescopic movements meets the needs of the vacuum pump 23 to move up and down.

[0041] Solenoid valve 25 is fixedly connected to the top rear side of the machine body 1. Air pump 26 is fixedly connected between solenoid valve 25 and inlet three-way valve 28. A circular pipe 29 is fixedly connected between inlet three-way valve 28 and filter box 30. Backup pipe 27 is fixedly connected to the normally closed end of inlet three-way valve 28. One end of backup pipe 27 is connected to an air supply system. Filter media 31 and filter plate 32 are fixedly connected inside filter box 30. Filter media 31 is positioned on the side of filter plate 32 near the circular pipe 29. When solenoid valve 25 is open, air pump 26 draws gas from inside filter box 30 through inlet three-way valve 28 and circular pipe 29. Furthermore, the outside air needs to be filtered by the filter plate 32 to remove dust, and then dried by the water filter material 31 before it can enter the round tube 29. The vacuum pump 26 discharges the filtered clean air into the machine body 1 through the solenoid valve 25. The vacuum pump 23, the exhaust three-way valve 18, the air guide pipe 21, the air collection pipe 22 and the sliding door 3 work together to ventilate and dissipate heat inside the machine body 1. When the normally closed end of the intake three-way valve 28 is opened, the vacuum pump 26 draws gas from the air supply system through the intake three-way valve 28 and the backup pipe 27, and then discharges it into the machine body 1 through the solenoid valve 25 to regulate the air pressure inside the machine body 1.

[0042] An air supply component is provided on one side of the air extraction component. The air supply component includes a solenoid valve 25, an air extraction pump 26, a backup pipe 27, an air inlet three-way valve 28, and a filter box 30. The air inlet three-way valve 28, the backup pipe 27, the air extraction pump 26, and the solenoid valve 25 work together with the air extraction component to regulate the gas composition inside the machine body 1.

[0043] Specifically, during the forging process of turbine disk powder material by the electrically connected hot pressing forming structure controlled by the operation panel 2, after the hot pressing forming structure drives the sliding door 3 to move down to seal the inside of the machine body 1, the hot pressing forming structure is controlled to stop moving, and at the same time the air extraction component works, so that the vacuum pump 23, butterfly valve 17 and air pressure sensor 20 work.

[0044] The working vacuum pump 23 draws air from the inside of the machine body 1 through the air inlet pipe 24, the exhaust three-way valve 18, the telescopic pipe 19 and the working butterfly valve 17. Since the sliding door 3 seals the inside of the machine body 1 at this time, the vacuum pump 23 draws out the air from the inside of the machine body 1 and then discharges it, thus emptying the air inside the machine body 1 which is in a sealed state.

[0045] This brings the interior of the machine body 1 closer to a vacuum environment, preventing oxidation reactions from occurring during the high-temperature forging process of the turbine disk powder material. It also reduces the likelihood of physicochemical reactions between the turbine disk powder material and trace elements in the air during the high-temperature forging process, thus ensuring the quality of the turbine disk powder material forging.

[0046] Furthermore, the air pressure sensor 20 monitors the air pressure inside the vertical pipe fixed by the telescopic tube 19. Since the vertical pipe is connected to the inside of the machine body 1 through the telescopic tube 19 and the butterfly valve 17 that is open, the air pressure sensor 20 monitors the air pressure inside the machine body 1 in real time and feeds it back to the operator on the control panel 2. The operator can control the operation of the air extraction component based on the air pressure value inside the machine body 1.

[0047] When the internal air pressure of the machine body 1 reaches the preset value, the hot pressing forming structure is controlled to work again through the operation panel 2. At this time, the hot pressing forming structure heats and pressurizes the turbine disk powder material to forge the turbine disk powder material into a blank. The butterfly valve 17 stops working and closes to ensure the internal sealing of the machine body 1.

[0048] Once the internal air pressure of the machine body 1 reaches the preset value, the air supply components can be controlled via the operation panel 2. The solenoid valve 25 opens, the normally closed end of the intake three-way valve 28 opens, and the suction pump 26 operates to draw air. At this time, the suction pump 26 draws inert gas from the air supply system through the intake three-way valve 28 and the spare pipe 27 fixedly connected to the normally closed end of the intake three-way valve 28. The inert gas drawn by the suction pump 26 is then delivered into the machine body 1 via the solenoid valve 25. Meanwhile, the normally open end of the exhaust three-way valve 18 closes, and the air pressure sensor 20 can detect the internal air pressure of the machine body 1 through the telescopic pipe 19 and the open butterfly valve 17. The gas inside the machine body 1 is blocked by the exhaust three-way valve 18 and cannot be discharged. The air pressure inside the machine body 1 is adjusted to the air pressure value required for hot pressing of turbine disk powder material by the air supply component. This avoids the reaction between the turbine disk powder material and oxygen, metal particles and special gases in the air during hot pressing, and ensures that the turbine disk powder material is hot pressed under the appropriate air pressure. This ensures the practicality of the vacuum powder forging equipment composed of the sliding door 3, hot pressing structure, air extraction component, air supply component, machine body 1, operation panel 2 and other structures, and meets the processing needs of different powder materials.

[0049] After the turbine disk powder material is hot-pressed and formed, the hot-pressed structure is controlled to stop heating and return to its original position a certain distance. At this time, there is a gap between the bottom of the sliding door 3 and the inside of the machine body 1. Then, the normally closed end of the exhaust three-way valve 18 is opened, the vacuum pump 23 is activated, the suction pump 26 is activated, and the solenoid valve 25 is opened via the operation panel 2. The activated suction pump 26 draws air through the intake three-way valve 28, the round pipe 29, and the filter box 30. After being filtered by the filter box 30, the air is delivered to the inside of the machine body 1 by the suction pump 26 through the opened solenoid valve 25, so that the air pressure inside the machine body 1 is restored.

[0050] Simultaneously operating, the vacuum pump 23 draws gas through the intake pipe 24, exhaust three-way valve 18, guide pipe 21, gas collection pipe 22, and sliding door 3 (details below). At this time, the vacuum pump 23 draws gas discharged through the gap between the bottom of the sliding door 3 and the machine body 1, collecting and discharging the high-temperature gas discharged from inside the machine body 1 to reduce environmental impact. Through the cooperation of the extraction and supply components, a controllable gas circulation structure is formed inside the machine body 1 after the hot-pressing molding structure is completed, centrally discharging the high-temperature exhaust gas generated during the hot-pressing of the turbine disk powder material.

[0051] Please refer to it again. Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 10 and Figure 11The machine body 1 has a sliding groove 4 inside, and the sliding door 3 is set inside the sliding groove 4. A connecting plate 8 is fixedly connected between the bottom side of the sliding door 3 and the hot-pressing structure. The hot-pressing structure is set inside the sealed space formed by the machine body 1 and the sliding door 3. The bottom of the sliding door 3 has a square groove 33, and the top of the sliding door 3 has multiple small holes 34. The bottom of the multiple small holes 34 is set inside the square groove 33. The gas collecting pipe 22 is fixedly connected to the top of the sliding door 3.

[0052] Specifically, after the turbine disk powder material is hot-pressed and formed, the hot-pressed structure is controlled to stop heating and reset a certain distance. At this time, there is a gap between the bottom of the sliding door 3 and the inside of the body 1.

[0053] At this time, the vacuum pump 23 operates by drawing gas from the inside of the gas guide pipe 21 through the normally closed end of the inlet pipe 24 and the exhaust three-way valve 18. The gas guide pipe 21 is fixedly connected to the gas collecting pipe 22. Furthermore, the gas inside the square groove 33 can enter the gas collecting pipe 22 through multiple small holes 34. The square groove 33 is located at the top of the gap between the bottom of the sliding door 3 and the inside of the machine body 1. Therefore, after the vacuum pump 23 operates, it draws gas from the inside of the square groove 33 through the inlet pipe 24, the exhaust three-way valve 18, the gas guide pipe 21, the gas collecting pipe 22, and the multiple small holes 34. This allows the square groove 33 to draw gas from the inside of the machine body 1 that is discharged through the gap, thus collecting and centrally processing the gas discharged from the inside of the machine body 1.

[0054] A connecting plate 8 is fixedly connected between the sliding door 3 and the hot-pressing structure. The hot-pressing structure drives the sliding door 3 to slide inside the sliding groove 4.

[0055] Please refer to it again. Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 9 The hot pressing forming structure also includes a hydraulic cylinder 5, a formwork 6, a hot pressing block 7, an electric heating structure 15, and a mold 16. The electric heating structure 15 is fixedly connected to the bottom of the inner cavity of the machine body 1, the mold 16 is set inside the electric heating structure 15, the hydraulic cylinder 5 is fixedly connected to the top of the machine body 1, the bottom end of the hydraulic cylinder 5 extends through the machine body 1 to the top of the inner cavity of the machine body 1, the formwork 6 is fixedly connected between the bottom of the hydraulic cylinder 5 and the hot pressing block 7, and the hot pressing block 7 is set on the top of the mold 16.

[0056] Specifically, hydraulic cylinder 5 controls the up-and-down movement of the hot pressing molding structure, I-beam 6 is used to install hot pressing block 7, which itself has a high temperature after operation, and electric heating structure 15 is used to support and limit the mold 16. Electric heating structure 15 heats mold 16 and the turbine disk powder material inside mold 16. Hydraulic cylinder 5 pushes I-beam 6 and hot pressing block 7 downward, and hot pressing block 7 enters the mold 16 to hot press the turbine disk powder material.

[0057] Please refer to it again. Figure 1 , Figure 3 , Figure 6 and Figure 7 The camera assembly includes a mounting frame 9, an electric push rod 10, a camera 11, two Z-shaped blocks 12, and two support springs 13. The mounting frame 9 is located inside the I-shaped frame 6. The electric push rod 10 is fixedly connected inside the mounting frame 9. The camera 11 is fixedly connected to the bottom of the electric push rod 10. The two Z-shaped blocks 12 are fixedly connected to the top of the I-shaped frame 6. The two support springs 13 are respectively fixedly connected between the two Z-shaped blocks 12 and the top two sides of the mounting frame 9. T-shaped rods 35 are provided inside the two support springs 13. The top of the T-shaped rods 35 passes through the Z-shaped blocks 12, and the bottom of the T-shaped rods 35 is fixedly connected to the mounting frame 9. Two top rods 14 are fixedly connected inside the body 1. The two top rods 14 are respectively located on both sides of the electric heating structure 15.

[0058] Specifically, after the turbine disk powder material is hot-pressed and formed, the hot-pressing structure is controlled to stop heating and move upward a certain distance. Before a gap forms between the bottom of the sliding door 3 and the inside of the body 1, the hot-pressing structure is controlled to stop moving. Since there is sufficient clearance between the bottom of the inner cavity of the sliding groove 4 and the bottom of the inner cavity of the body 1, such as... Figure 9 As shown, the sliding door 3, which moves synchronously with the hot-pressed structure, can satisfy the above conditions.

[0059] After the hot-pressing structure stops moving upwards, the electrically connected electric push rod 10, controlled by the operation screen 2, pushes the camera 11 away from the mounting frame 9. The tilted camera 11 captures the process of the turbine disk powder material forming a blank after hot pressing inside the mold 16. The data captured by the camera 11 is displayed on the operation screen 2, allowing the operator to assess the processing quality of the turbine disk powder material blank. It should also be noted that the two cameras 11 mentioned in this application can be optical microscopes and scanning electron microscopes, respectively.

[0060] After the vacuum powder forging equipment, which consists of sliding door 3, hot pressing forming structure, air extraction component, air supply component, machine body 1, and operation panel 2, has completed hot pressing and is in a sealed state, the quality of the turbine disk powder material billet can be judged. Secondary processing can be carried out quickly and efficiently, reducing the time cost required for billet rework and the resource cost of adjusting the working status of the vacuum powder forging equipment.

[0061] When the hot press block 7 enters the mold 16 to hot press the turbine disk powder material, the push rod 14 pushes up the mounting frame 9 supported by the support spring 13, the camera 11 stays at the top of the push rod 14, and the T-shaped rod 35 passes through the Z-shaped block 12 to limit the movement of the mounting frame 9.

[0062] After the hot pressing structure stops heating and moves upward a certain distance, the hot pressing block 7 leaves the mold 16 and there is a gap between them. At this time, the bottom of the camera 11 is supported by the push rod 14 and aligned with the gap between the hot pressing block 7 and the mold 16. After the electric push rod 10 works, the mounting bracket 9 moves upward under the action of the electric push rod 10, so that the camera 11 is unobstructed on one side to shoot the inside of the mold 16.

[0063] A method for vacuum powder forging of a turbine disk includes the following steps:

[0064] Step 1: Control the electrically connected thermoforming structure to move down through the operation panel 2. The thermoforming structure drives the sliding door 3 to seal the inside of the machine body 1.

[0065] Step 2: The operation panel 2 controls the operation of the vacuum pumping unit to bring the interior of the machine body 1 closer to a vacuum environment. The vacuum pumping unit is stopped working based on the air pressure value detected by the air pressure sensor 20.

[0066] Step 3: Control the electrically connected gas supply component through the operation panel 2 to replenish inert gas into the machine body 1;

[0067] Step 4: Control the operation of the electrically connected hot pressing molding structure through the operation panel 2.
