DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present invention provides a technical solution: Embodiment 1: Combination Figure 1 to Figure 2 -6. An isothermal hot compression device for high-temperature alloys, comprising a mounting seat 1, a compressor 4 is fixedly connected to the top of the mounting seat 1, a supporting mechanism 3 is arranged inside the mounting seat 1, and an isothermal mounting mechanism 2 is arranged on the top of the mounting seat 1.

[0021] The isothermal installation mechanism 2 includes a high-temperature furnace 24, which is fixedly connected to the middle of the top of the mounting seat 1. A support frame 205 is fixedly connected to the inner wall of the high-temperature furnace 24. A clamp 206 is fixedly connected to the side of the support frame 205 close to the middle of the high-temperature furnace 24. A fan blade 207 is arranged on one side of the clamp 206. A cross plate 208 is rotatably connected to the top of the fan blade 207. The cross plate 208 is fixedly connected to the inner wall of the high-temperature furnace 24. A cover body 25 is arranged on the top of the high-temperature furnace 24. The mounting frame 203 is fixedly connected to both sides of the top of the cover body 25. A sliding plate 209 is fixedly connected to the bottom of the mounting frame 203. A vertical rod 28 is slidably connected to the sliding plate 209. The top of the vertical rod 28 is fixedly connected to a limiting plate 21. The bottom of the vertical rod 28 is fixedly connected to a support column 22. The support column 22 is fixedly connected to the top of the mounting seat 1. A spring 26 is sleeved on the surface of the vertical rod 28. The spring 26 is arranged at the bottom of the sliding plate 209.

[0022] Furthermore, a side of the sliding plate 209 away from the vertical rod 28 is fixedly connected to a cylinder 23 , a bottom of the cylinder 23 is fixedly connected to a support seat 27 , and the support seat 27 is fixedly connected to the top of the mounting seat 1 .

[0023] Furthermore, a circular groove is formed at the center of the cover body 25 , and a first support member 204 is fixedly connected to the top of the cover body 25 . A forged member 201 is inserted into the first support member 204 , and the forged member 201 is designed to be circular.

[0024] Furthermore, positioning pieces 202 are fixedly connected on both sides of the surface of the forged piece 201, a placement seat is provided at the bottom of the positioning piece 202, and the placement seat is fixedly connected to the top of the mounting frame 203. Limiting grooves are provided on both sides of the positioning piece 202, and limiting rods 29 are inserted in the limiting grooves, and the limiting rods 29 are fixedly connected to the top of the placement seat.

[0025] Furthermore, a thread is provided on the surface of the limit rod 29, and a locking nut is threadedly connected to the surface of the limit rod 29, and the locking nut is arranged at the top of the positioning member 202. During the isothermal hot compression process, the high-temperature alloy will undergo plastic deformation, which is a complex and critical physical process. As the forging compression continues, the dislocation density inside the high-temperature alloy continues to increase. Dislocation is a defect in the crystal. The increase in its density will make the atoms inside the alloy more tightly arranged, thereby producing a work hardening phenomenon. This work hardening phenomenon directly leads to a significant improvement in the strength and hardness of the high-temperature alloy.

[0026] Embodiment 2: See also Figure 7 On the basis of the first embodiment, the supporting mechanism 3 further comprises a placement groove, the placement groove is opened in the mounting seat 1, and placement plates 32 are fixedly connected on both sides of the placement groove, a sliding groove is opened in the placement plate 32, a sliding rod 31 is slidably connected in the sliding groove, a baffle 34 is fixedly connected to the top of the sliding rod 31, and the baffle 34 is arranged in the placement groove.

[0027] Furthermore, the baffle 34 is designed to be rectangular and movable. A second support member 33 is fixedly connected to the middle of the bottom of the baffle 34. A threaded rod 35 is connected to the inner thread of the second support member 33. A rotating member is fixedly connected to the front side of the threaded rod 35. A limit frame 36 is rotatably connected to the surface of the threaded rod 35. The limit frame 36 is fixedly connected to the front surface of the mounting seat 1. As the baffle 34 moves, the high-temperature alloy loses its support and falls into the interior of the mounting seat 1. In this way, the purpose of removing the high-temperature alloy can be easily and conveniently achieved. The whole process is orderly, ensuring the efficiency and stability of the high-temperature alloy processing process.

[0028] In the actual operation process, first, the compressor 4 is tightly connected to the high temperature furnace 24. As a key device for providing stable air pressure, the connection between the compressor 4 and the high temperature furnace 24 has been carefully designed to ensure that there will be no problems such as gas leakage during the operation. After the compressor 4 is started, it begins to continuously and stably provide air pressure to the high temperature furnace 24; In this process, driven by air pressure, the fan blades 207 start to rotate. The design of the fan blades 207 is ingenious, and its size, shape and installation angle have been precisely calculated. When the fan blades 207 rotate, they will generate uniform and stable airflow, which circulates inside the high-temperature furnace 24, so that the air pressure in various areas inside the high-temperature furnace 24 can be kept consistent. This consistency of air pressure is very important for maintaining the uniformity of the temperature inside the high-temperature furnace 24, because in a high-temperature environment, even a slight difference in air pressure may lead to uneven temperature distribution, and the rotation of the fan blades 207 effectively avoids this situation, thereby achieving isothermal heating of the high-temperature alloy; Next, the cylinder 23 is started. The cylinder 23 plays an important role in the whole system. When the cylinder 23 is started, it will generate a strong driving force, which acts on the sliding plate 209. The cooperation between the sliding plate 209 and the vertical rod 28 is very precise. The vertical rod 28 provides a stable guide for the sliding plate 209 to slide up and down. Under the action of the cylinder 23, the sliding plate 209 slides upward smoothly on the surface of the vertical rod 28, thereby driving the cover body 25 connected thereto to open; Subsequently, with the help of external auxiliary working equipment, the high-temperature alloy is placed between the pre-set clamps 206 on both sides of the high-temperature furnace 24. The design of these clamps 206 fully considers the shape and size of the high-temperature alloy. The clamping force of the clamps 206 is moderate and stable. They can firmly fix the high-temperature alloy to prevent the high-temperature alloy from shaking due to external factors (such as air flow impact, slight vibration of the equipment, etc.) during the subsequent heating process, because the shaking of the high-temperature alloy during the heating process may cause uneven heating, thereby affecting the processing quality; Next, the positioning member 202 is accurately placed on the top of the placement seat. At the moment of placement, the limiting rod 29 can be accurately inserted into the interior of the positioning member 202. The precision of this fit is extremely high. Then, the locking nut is carefully threaded onto the surface of the limiting rod 29. By rotating the locking nut, the tightening force of the locking nut on the positioning member 202 is gradually increased, thereby firmly fixing the positioning member 202. After completing the above steps, the cylinder 23 is started again. At this time, the cylinder 23 starts to perform a reciprocating telescopic motion. The power generated by this reciprocating motion is transmitted to the forging part 201 through a series of transmission mechanisms, driving the forging part 201 to move up and down. During the up and down movement of the forging part 201, it will continue to perform isothermal forging compression on the high-temperature alloy. During the isothermal hot compression process, the high-temperature alloy will undergo plastic deformation. This is a complex and critical physical process. As the forging compression continues, the dislocation density inside the high-temperature alloy continues to increase. Dislocation is a defect in the crystal. The increase in its density will make the atoms inside the alloy more tightly arranged, thereby producing a work hardening phenomenon. This work hardening phenomenon directly leads to a significant improvement in the strength and hardness of the high-temperature alloy. When the high-temperature alloy is processed, it needs to be taken out from the high-temperature furnace 24. At this time, the rotating part is rotated. The rotating part and the threaded rod 35 are connected by a special connecting structure. The rotation of the rotating part can accurately drive the threaded rod 35 to rotate. When the threaded rod 35 rotates, the threads on its surface interact with the surrounding structure, thereby generating a forward thrust. This thrust acts on the baffle 34, driving the baffle 34 to move stably to the front side. As the baffle 34 moves, the high-temperature alloy loses its support and falls into the inside of the mounting seat 1. In this way, the purpose of taking out the high-temperature alloy can be easily and conveniently achieved. The whole process is orderly, ensuring the efficiency and stability of the high-temperature alloy processing process.
