This step helps to release the internal stress of the niobium alloy and promote the recrystallization of the niobium alloy grains. High-temperature annealing is a precise technological process, and its parameters (such as temperature, time, and cooling rate) need to be precisely controlled according to the requirements of a specific alloy and the final application to ensure that the desired material properties are optimally optimized.

The annealing furnace is arranged on the bottom plate, the heat preservation and cooling chamber is arranged inside one side of the annealing furnace, the heating chamber is arranged inside the other side of the annealing furnace, the moving component is arranged inside the annealing furnace, the placement plate is arranged on the moving adjustment component, the cavity-changing adjustment component is arranged on the annealing furnace, and the waste heat utilization component is arranged on the annealing furnace. This patent belongs to the technical field of niobium alloys, and specifically refers to an energy-saving and environmental-friendly niobium alloy annealing device that is convenient for transferring the annealed profiles, reduces heat waste, re-uses waste heat, and improves work efficiency.

[0004] Currently, the niobium alloy high-temperature annealing and homogenization processing devices on the market still have the following problems: When performing high-temperature annealing on niobium alloys, it is necessary to first heat the niobium alloys. During the heating process, the general heating method is prone to uneven heating. In particular, the heating speed of the back surface of the niobium alloy is much slower than that of the front surface, which is likely to cause uneven distribution of internal stress and result in cracks in the material. Therefore, it is necessary to design a processing device that can uniformly heat niobium alloys. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a niobium alloy high-temperature annealing and homogenization processing device, which solves the problem that when performing high-temperature annealing on niobium alloys, it is necessary to first heat the niobium alloys. During the heating process, the general heating method is prone to uneven heating. In particular, the heating speed of the back surface of the niobium alloy is much slower than that of the front surface, which is likely to cause uneven distribution of internal stress and result in cracks in the material, as mentioned in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A niobium alloy high-temperature annealing homogenization processing device, comprising a box body, on the top surface of which a blower is fixed, on the top of the inner wall of which a heating plate is fixed, and inside which a return air device, a cooling device, a impurity removal device and a fixing device are arranged. The return air device includes a slider, a cylinder, a containing box, a telescopic rod and a return air plate. The slider is slidably installed on the bottom of the inner wall of the box body, the cylinder is rotatably installed on the top surface of the slider, the containing box is fixed on the top of the cylinder, the telescopic rod is fixed on the top surface of the slider, one end of the return air plate is hinged to the top surface of the slider, and the bottom surface of the return air plate is hinged to the telescopic end of the telescopic rod. Place the niobium alloy on the containing box, start the blower, and the blower blows out air flow. The air flow blows the heat generated by the heating plate onto the niobium alloy, and the air flow can make the heat of the heating plate spread throughout the right half of the box body as soon as possible. Start the telescopic rod, and the telescopic rod drives the return air plate to swing up and down. The return air plate is used to return the air flow directly blown by the blower, so as to heat the bottom surface of the niobium alloy, making the heating more uniform and avoiding cracks in the material caused by uneven distribution of internal stress.

[0007] According to the above technical solution, the return air device further includes a connecting plate, a circular ring, a small cylinder and a return spring rod. The connecting plate is fixed on the top surface of the return air plate, the circular ring is slidably installed on the outer wall of the cylinder, the circular ring is located on the movement track of the connecting plate, one end of the small cylinder is fixed on the inner wall of the circular ring, an arc-shaped groove is formed on the outer wall of the cylinder, and the other end of the small cylinder is slidably installed on the inner wall of the arc-shaped groove. One end of the return spring rod is fixed on the top surface of the slider, and the other end of the return spring rod is fixed on the bottom surface of the circular ring. When the telescopic rod drives the return air plate to swing downwards, the return air plate drives the connecting plate to rotate and tilt upwards. The connecting plate pushes the circular ring upwards, and the circular ring drives the small cylinder to move upwards. The small cylinder moves along the arc track on the surface of the cylinder, thereby driving the cylinder to rotate. The cylinder drives the containing box to rotate half a circle. When the return air plate drives the connecting plate to rotate and swing upwards, the return spring rod contracts downwards, and the return spring rod drives the circular ring to return downwards. In this way, the containing box can rotate back and forth half a circle, further improving the heating effect on the niobium alloy and making the returned air flow blow more evenly onto the bottom surface of the niobium alloy.

[0008] According to the above technical solution, the cooling device includes a screw rod, a protective frame, a sealing plate and an inverted triangular block. The screw rod is fixed to the output end of the motor, and the motor is fixed to the right side of the box body. The protective frame is fixed to both sides of the slider. The sealing plate is slidably installed on the top surface of the box body. A spring is provided between the top of the sealing plate and the top surface of the box body. The inverted triangular block is fixed to both sides of the sealing plate. The inverted triangular block is located on the movement track of the protective frame. When annealing the niobium alloy, place the niobium alloy on the storage box, start the motor, the motor drives the screw rod to rotate, the screw rod drives the slider to move to the right, the slider drives the cylinder to move to the right, the cylinder drives the storage box to move to the right, the storage box drives the niobium alloy to move to the right. At the same time, the slider drives the protective frame to move to the right. During the movement of the protective frame, the inverted triangular block is squeezed, so that the inverted triangular block moves upward, and the inverted triangular block drives the sealing plate to move upward, so that the cooling cavity and the heating cavity are connected and opened. When the protective frame completely moves to the right heating cavity, under the action of the spring force, the sealing plate moves downward to separate the two cavities. When the heating is over, move the storage box in the reverse direction so that the storage box reaches the cooling cavity, so that the annealed niobium alloy can be directly cooled, avoiding taking out the heated niobium alloy for cooling, resulting in a change in the cooling temperature and poor annealing effect, and also avoiding harm to the staff caused by high-temperature materials.

[0009] According to the above technical solution, the cooling device further includes a cross block, a U-shaped groove, a round rod and a sliding plate. The cross block is fixed to the inner wall of the box body. The U-shaped groove is fixed to the bottom surface of the cross block. The round rod is fixed to the inner side of the inverted triangular block. The round rod is slidably installed on the inner wall of the U-shaped groove. The sliding plate is fixed to the bottom of the inner wall of the U-shaped groove through a spring. The sliding plate is located on the movement track of the round rod. After repeated use, the downwardly resilient sealing plate repeatedly impacts the bottom connection base for a long time, which will cause damage to the sealing plate and reduce the sealing effect, resulting in the high temperature in the heating cavity being conducted to the cooling cavity, and the heat preservation effects of both cavities will decrease. Therefore, when the sealing plate falls along the U-shaped groove, the sealing plate drives the round rod to descend, and the sealing plate will first impact the sliding plate on the inner wall of the U-shaped groove, and the spring between the sliding plate and the inner wall of the U-shaped groove is used to buffer and weaken the impact force, improving the service life of the sealing plate.

[0010] According to the above technical solution, the impurity removal device includes a bottom box, a rebound block, a knocking block and a semi-cylinder. The bottom box is fixed on the inner wall of the box body. The rebound block penetrates and is slidably installed on the bottom surface of the bottom box. A spring is arranged between the rebound block and the inner wall of the bottom box. The knocking block is fixed at the bottom of the rebound block. The semi-cylinder is fixed on the top surface of the protection frame. The rebound block is located on the movement track of the semi-cylinder. During the annealing process, the recrystallization of grains is achieved through a certain diffusion process, and impurities may affect the diffusion rate, resulting in inconsistent growth of grains in the surface and internal regions, which will affect the structural strength of the material. During the process of moving the niobium alloy in the storage box to the heating chamber, the protection frame drives the semi-cylinder to move to the right. During the movement, the semi-cylinder squeezes the rebound block, causing the rebound block to retract into the bottom box. When the semi-cylinder leaves, under the action of the spring force, the rebound block pops out downward, and the rebound block drives the knocking block to move downward, using the knocking block to knock and vibrate the niobium alloy, so that the impurities on the surface of the niobium alloy fall off, achieving the purpose of cleaning impurities and improving the finished product effect of annealing.

[0011] According to the above technical solution, the impurity removal device further includes a collection box, an inclined plate and an arc-shaped block. The collection box is fixed on the bottom surface of the inner wall of the box body. A collection through groove is opened on the top surface of the collection box. A through discharge port is opened between the left side of the box body and the left side of the collection box. The inclined plate is hinged on the inner wall of the collection box. A spring is arranged between the inclined plate and the bottom surface of the inner wall of the collection box. The arc-shaped block is fixed on the top surface of the inclined plate. The arc-shaped block is located on the movement track of the slider. The impurities that fall off by vibration will fall into the collection box. Every time the protection frame moves to the left, it will squeeze the arc-shaped block, causing the arc-shaped block to move downward. The arc-shaped block drives the inclined plate to move downward, and the spring between the bottom surface of the inclined plate and the inner wall of the collection box contracts. When the protection frame moves away to the right, the arc-shaped block is not squeezed. Under the action of the spring force, the inclined plate will pop up upward, causing the inclined plate to vibrate and activate the impurities falling on the top surface, so that the impurities leave from the discharge port at the bottom left of the box body, achieving the purpose of automatic impurity removal and improving the flexibility of impurity cleaning.

[0012] According to the above technical solution, the fixing device includes an elastic square rod, a pressing plate, a limiting block and a metal elastic sheet. The elastic square rod is slidably installed on the top of the storage box. The pressing plate is fixed at the top end of the elastic square rod. The limiting block is fixed on the left side of the storage box. The limiting block is located on the movement track of the elastic square rod. Both ends of the metal elastic sheet are slidably installed on the bottom surface of the pressing plate. When placing the niobium alloy on the storage box, move the elastic square rod towards the middle, and use the pressing plate to press on the niobium alloy to achieve the purpose of fixing the niobium alloy, avoiding the niobium alloy being thrown out during the subsequent rotation of the storage box. Use the limiting block to fix the bottom end of the elastic square rod. When unlocking is required, press the sliding block at the top end of the limiting block downward to freely move the elastic square rod, making both fixing and unlocking very convenient. At the same time, the setting of the metal elastic sheet makes the pressing plate not directly bounce onto the niobium alloy body when fixing the niobium alloy, avoiding scratching the niobium alloy body by the pressing plate.

[0013] According to the above technical solution, the fixing device further includes a moving block, a chamfering block, a hollow square tube, and an adjusting pressing block. The moving block is slidably mounted on the bottom surface of the pressing plate. The moving block is located on the movement track of the metal elastic sheet. The hollow square tube is fixed inside the fixed end of the elastic square rod. The chamfering block is slidably mounted on the top of the hollow square tube. The chamfering block is located on the movement track of the moving block. The adjusting pressing block is slidably mounted inside the hollow square tube. When the metal elastic sheet is extruded by the niobium alloy and extends to both sides, the metal elastic sheet pushes the moving block, the moving block pushes and extrudes the chamfering block, the chamfering block moves downward and retracts into the interior of the hollow square tube, the air in the hollow square tube is extruded, and the air extrudes the adjusting pressing block to pop out, so that the metal elastic sheet and the adjusting pressing block push and cooperate with each other, automatically adapting to fixedly clamp the top surface and the side surface of niobium alloys with different shapes.

[0014] The present invention provides a niobium alloy high-temperature annealing and homogenizing processing device, which has the following beneficial effects: (1) Through the setting of the air return device in the present invention, the slider, the column body, the storage box, the telescopic rod, and the air return plate cooperate. When the telescopic rod is started, the telescopic rod drives the air return plate to swing up and down, and the air return plate returns the airflow directly blown by the blower, so as to achieve the purpose of heating the bottom surface of the niobium alloy, making the heating more uniform and avoiding cracks in the material caused by uneven distribution of internal stress; the connecting plate, the circular ring, the small cylinder, and the spring-back rod cooperate. The connecting plate pushes the circular ring upward, the circular ring drives the small cylinder to move upward, and the small cylinder moves along the arc track on the surface of the column body, thereby driving the column body to rotate. The column body drives the storage box to make a half-turn rotation. When the air return plate drives the connecting plate to rotate and swing upward, the spring-back rod contracts downward, and the spring-back rod drives the circular ring to return downward. In this way, the storage box can make a half-turn rotation back and forth, further improving the heating effect on the niobium alloy and making the returned air flow blow more evenly to the bottom surface of the niobium alloy.

[0015] (2) Through the setting of the cooling device, the present invention enables the cooperation of the screw, the protective frame, the sealing plate and the inverted triangular block. During the movement of the protective frame, the inverted triangular block is squeezed, causing the inverted triangular block to move upward. The inverted triangular block drives the sealing plate to move upward, enabling the cooling cavity and the heating cavity to communicate and open. When the protective frame completely moves to the right heating cavity, under the action of the spring force, the sealing plate moves downward to separate the two cavities. After heating is completed, the storage box is moved in the reverse direction, causing the storage box to reach the cooling cavity, thereby directly cooling the annealed niobium alloy, avoiding taking out the heated niobium alloy for cooling, resulting in changes in the cooling temperature and poor annealing effect, and also avoiding harm to workers caused by high-temperature materials. It also enables the cooperation of the cross block, the U-shaped groove, the round rod and the sliding plate. After repeated use, the downwardly bouncing sealing plate impacts the bottom connection base for a long time, causing damage to the sealing plate and reducing the sealing effect, resulting in the high temperature of the heating cavity being conducted to the cooling cavity, and the heat preservation effects of both cavities will decline. Therefore, when the sealing plate falls along the U-shaped groove, the sealing plate drives the round rod to descend, and the sealing plate will first impact the sliding plate on the inner wall of the U-shaped groove. The spring between the sliding plate and the inner wall of the U-shaped groove is used to buffer and weaken the impact force, improving the service life of the sealing plate.

[0016] (3) Through the setting of the impurity removal device, the present invention enables the cooperation of the bottom box, the spring-back block, the knocking block and the semi-cylinder. The protective frame drives the semi-cylinder to move to the right. During the movement of the semi-cylinder, the spring-back block is squeezed, causing the spring-back block to retract into the bottom box. When the semi-cylinder leaves, under the action of the spring force, the spring-back block pops downward, and the spring-back block drives the knocking block to move downward. The knocking block is used to knock and vibrate the niobium alloy, causing the impurities on the surface of the niobium alloy to fall off, achieving the purpose of cleaning impurities and improving the finished product effect of annealing. It also enables the cooperation of the collection box, the inclined plate and the arc-shaped block. Each time the protective frame moves to the left, it will squeeze the arc-shaped block, causing the arc-shaped block to move downward. The arc-shaped block drives the inclined plate to move downward, and the spring between the bottom surface of the inclined plate and the inner wall of the collection box contracts. When the protective frame moves away to the right, the arc-shaped block is not squeezed. Under the action of the spring force, the inclined plate will pop upward, causing the inclined plate to vibrate and loosen the impurities falling on the top surface, enabling them to leave the discharge port at the bottom left of the box body along the inclined plate, achieving the purpose of automatic impurity removal and improving the flexibility of impurity cleaning.

[0017] (4) Through the setting of the fixing device, the elastic square rod, the pressing plate, the limiting block and the metal elastic sheet cooperate to move the elastic square rod towards the middle, and the pressing plate is used to press on the niobium alloy, so as to achieve the purpose of fixing the niobium alloy, avoiding the niobium alloy from being thrown out during the subsequent rotation of the storage box. The limiting block is used to fix the bottom end of the elastic square rod. When unlocking is required, pressing down the sliding block at the top of the limiting block can freely move the elastic square rod, making both fixing and unlocking very convenient. At the same time, the setting of the metal elastic sheet makes the pressing plate not directly bounce onto the niobium alloy body when fixing the niobium alloy, avoiding scratching the niobium alloy body by the pressing plate; the moving block, the chamfering block, the hollow square tube and the adjusting pressing block cooperate, the metal elastic sheet pushes the moving block, the moving block pushes and extrudes the chamfering block, the chamfering block moves downward and retracts into the interior of the hollow square tube, the air in the hollow square tube is squeezed, and the squeezed air pushes the adjusting pressing block to pop out, so that the metal elastic sheet and the adjusting pressing block push and cooperate with each other, automatically adapting to fix and clamp the top and side surfaces of niobium alloys with different shapes.

Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Please refer to Figures 1-9 , an embodiment of the present invention is: a niobium alloy high-temperature annealing and homogenizing processing device, including a box body 11, a blower 12 is fixed on the top surface of the box body 11. Place the niobium alloy on the storage box 23, start the blower 12, the blower 12 blows out air flow, a heating plate 13 is fixed on the top of the inner wall of the box body 11, and the air flow blows the heat generated by the heating plate 13 onto the niobium alloy. The air flow can make the heat of the heating plate 13 quickly spread throughout the right half of the box body 11. An air return device 2 and a cooling device 3 are arranged inside the box body 11. The air return device 2 includes a slider 21, a cylinder 22, a storage box 23, a telescopic rod 24 and an air return plate 25. The slider 21 is slidably installed on the bottom of the inner wall of the box body 11, the cylinder 22 is rotatably installed on the top surface of the slider 21, the storage box 23 is fixed on the top of the cylinder 22, the telescopic rod 24 is fixed on the top surface of the slider 21. Start the telescopic rod 24, one end of the air return plate 25 is hinged on the top surface of the slider 21, the bottom surface of the air return plate 25 is hinged on the telescopic end of the telescopic rod 24, and the telescopic rod 24 drives the air return plate 25 to swing up and down. The air flow directly blown by the blower 12 is returned by using the air return plate 25, so as to achieve the purpose of heating the bottom surface of the niobium alloy, making the heating more uniform, and avoiding cracks in the material caused by uneven distribution of internal stress.

[0022] The air return device 2 further includes a connecting plate 26, a circular ring 27, a small cylinder 28 and a resilient rod 29. The connecting plate 26 is fixed to the top surface of the air return plate 25. When the telescopic rod 24 drives the air return plate 25 to swing downward, the air return plate 25 drives the connecting plate 26 to rotate and tilt upward. The circular ring 27 is slidably mounted on the outer wall of the column 22, and the circular ring 27 is located on the movement track of the connecting plate 26. The connecting plate 26 pushes the circular ring 27 upward. One end of the small cylinder 28 is fixed to the inner wall of the circular ring 27, and the circular ring 27 drives the small cylinder 28 to move upward. An arc-shaped groove is formed in the outer wall of the column 22, and the other end of the small cylinder 28 is slidably mounted on the inner wall of the arc-shaped groove. The small cylinder 28 moves along the arc track on the surface of the column 22, thereby driving the column 22 to rotate. The column 22 drives the storage box 23 to make a half-turn. One end of the resilient rod 29 is fixed to the top surface of the slider 21. When the air return plate 25 drives the connecting plate 26 to rotate and swing upward, the resilient rod 29 contracts downward. The other end of the resilient rod 29 is fixed to the bottom surface of the circular ring 27, and the resilient rod 29 drives the circular ring 27 to reset downward. In this way, the storage box 23 can make a half-turn back and forth, further improving the heating effect on the niobium alloy, so that the returned air can be blown more evenly onto the bottom surface of the niobium alloy.

[0023] The cooling device 3 includes a screw rod 31, a protective frame 32, a sealing plate 33 and an inverted triangular block 34. The screw rod 31 is fixed to the output end of the motor, and the motor is fixed to the right side of the box body 11. When annealing the niobium alloy, the niobium alloy is placed on the storage box 23, and the motor is started. The motor drives the screw rod 31 to rotate, and the screw rod 31 drives the slider 21 to move to the right. The protective frame 32 is fixed to both sides of the slider 21, and the slider 21 drives the column 22 to move to the right. The column 22 drives the storage box 23 to move to the right, and the storage box 23 drives the niobium alloy to move to the right. At the same time, the slider 21 drives the protective frame 32 to move to the right. The sealing plate 33 is slidably mounted on the top surface of the box body 11, and a spring is provided between the top of the sealing plate 33 and the top surface of the box body 11. The inverted triangular block 34 is fixed to both sides of the sealing plate 33, and the inverted triangular block 34 is located on the movement track of the protective frame 32. During the movement of the protective frame 32, it squeezes the inverted triangular block 34, causing the inverted triangular block 34 to move upward. The inverted triangular block 34 drives the sealing plate 33 to move upward, so that the cooling cavity and the heating cavity are connected and opened. When the protective frame 32 completely moves to the right heating cavity, under the action of the spring force, the sealing plate 33 moves downward to separate the two cavities. After the heating is completed, the storage box 23 is moved in the reverse direction, so that the storage box 23 reaches the cooling cavity, so that the annealed niobium alloy can be directly cooled, avoiding taking out the heated niobium alloy for cooling, resulting in a change in the cooling temperature and a poor annealing effect, and also avoiding harm to the staff caused by high-temperature materials.

[0024] The cooling device 3 further includes a cross block 35, a U-shaped groove 36, a round rod 37, and a sliding plate 38. The cross block 35 is fixed to the inner wall of the box body 11, the U-shaped groove 36 is fixed to the bottom surface of the cross block 35, and the round rod 37 is fixed to the inner side of the inverted triangular block 34. After multiple uses, the downwardly resilient sealing plate 33 repeatedly impacts the bottom connection base, which can cause damage to the sealing plate 33 and reduce the sealing effect, resulting in the high temperature in the heating chamber being conducted to the cooling chamber, and the heat preservation effects of both chambers will decline. Therefore, when the sealing plate 33 drops along the U-shaped groove 36, the sealing plate 33 drives the round rod 37 to descend. The round rod 37 is slidably installed on the inner wall of the U-shaped groove 36. The sliding plate 38 is fixed to the bottom of the inner wall of the U-shaped groove 36 by a spring. The sliding plate 38 is located on the movement trajectory of the round rod 37. The sealing plate 33 will first impact the sliding plate 38 on the inner wall of the U-shaped groove 36, and the spring between the sliding plate 38 and the inner wall of the U-shaped groove 36 is used to buffer and weaken the impact force, thereby improving the service life of the sealing plate 33.

[0025] During use, place the niobium alloy on the storage box 23, start the blower 12, and the blower 12 blows out air flow. The air flow blows the heat generated by the heating plate 13 onto the niobium alloy. The air flow can make the heat of the heating plate 13 quickly cover the right half of the entire box body 11. Start the telescopic rod 24, and the telescopic rod 24 drives the air return plate 25 to swing up and down. The air return plate 25 is used to return the air flow directly blown by the blower 12, so as to achieve the purpose of heating the bottom surface of the niobium alloy, making the heating more uniform and avoiding cracks in the material caused by uneven distribution of internal stress. When the telescopic rod 24 drives the air return plate 25 to swing downward, the air return plate 25 drives the connecting plate 26 to rotate and tilt upward. The connecting plate 26 pushes the ring 27 upward, and the ring 27 drives the small cylinder 28 to move upward. The small cylinder 28 moves along the arc trajectory on the surface of the column 22, thereby driving the column 22 to rotate. The column 22 drives the storage box 23 to make a half-turn. When the air return plate 25 drives the connecting plate 26 to rotate and swing upward, the resilient rod 29 contracts downward, and the resilient rod 29 drives the ring 27 to return downward. In this way, the storage box 23 can make a half-turn back and forth, further improving the heating effect on the niobium alloy and making the returned air flow blow more evenly onto the bottom surface of the niobium alloy.

[0026] When annealing a niobium alloy, place the niobium alloy on the storage box 23, start the motor, the motor drives the screw 31 to rotate, the screw 31 drives the slider 21 to move to the right, the slider 21 drives the cylinder 22 to move to the right, the cylinder 22 drives the storage box 23 to move to the right, the storage box 23 drives the niobium alloy to move to the right. At the same time, the slider 21 drives the protective frame 32 to move to the right. During the movement of the protective frame 32, it squeezes the inverted triangular block 34, causing the inverted triangular block 34 to move upward. The inverted triangular block 34 drives the sealing plate 33 to move upward, so that the cooling cavity and the heating cavity are connected and opened. When the protective frame 32 completely moves to the right heating cavity, under the action of the spring force, the sealing plate 33 moves downward to separate the two cavities. After heating is completed, move the storage box 23 in the reverse direction so that the storage box 23 reaches the cooling cavity, so that the annealed niobium alloy can be directly cooled, avoiding taking out the heated niobium alloy for cooling, resulting in a change in the cooling temperature and poor annealing effect, and also avoiding harm to the staff caused by high-temperature materials; after multiple uses, the downward-sprung sealing plate 33 hits the bottom connection base for a long time, which will cause damage to the sealing plate 33 and reduce the sealing effect, resulting in the high temperature of the heating cavity being conducted to the cooling cavity, and the heat preservation effects of the two cavities will both decrease. Therefore, when the sealing plate 33 falls along the U-shaped groove 36, the sealing plate 33 drives the round rod 37 to descend. The sealing plate 33 will first hit the sliding plate 38 on the inner wall of the U-shaped groove 36, and use the spring between the sliding plate 38 and the inner wall of the U-shaped groove 36 to buffer and weaken the impact force, improving the service life of the sealing plate 33.

[0027] Please refer to Figures 1-9 , on the basis of the above embodiment, in another embodiment of the present invention, it further includes a decontamination device 4 and a fixing device 5.

[0028] The decontamination device 4 includes a bottom box 41, a rebounding block 42, a knocking block 43 and a semi-cylinder 44. The bottom box 41 is fixed on the inner wall of the box body 11. The rebounding block 42 passes through and is slidably installed on the bottom surface of the bottom box 41. A spring is provided between the rebounding block 42 and the inner wall of the bottom box 41. The knocking block 43 is fixed to the bottom of the rebounding block 42. The semi-cylinder 44 is fixed on the top surface of the protective frame 32. During the annealing process, the recrystallization of grains is achieved through a certain diffusion process, and impurities may affect the diffusion rate, resulting in inconsistent growth of grains in the surface and internal regions, which will affect the structural strength of the material. During the movement of the niobium alloy in the storage box 23 to the heating cavity, the protective frame 32 drives the semi-cylinder 44 to move to the right. The rebounding block 42 is located on the movement track of the semi-cylinder 44. During the movement of the semi-cylinder 44, it squeezes the rebounding block 42, causing the rebounding block 42 to retract into the bottom box 41. When the semi-cylinder 44 leaves, under the action of the spring force, the rebounding block 42 pops downward, and the rebounding block 42 drives the knocking block 43 to move downward, using the knocking block 43 to knock and vibrate the niobium alloy, so that the impurities on the surface of the niobium alloy fall off, achieving the purpose of cleaning impurities and improving the finished product effect of annealing.

[0029] The impurity removal device 4 further includes a collection box 45, an inclined plate 46 and an arc-shaped block 47. The collection box 45 is fixed on the bottom surface of the inner wall of the box body 11. A collection through groove is provided on the top surface of the collection box 45. A through discharge port is provided between the left side of the box body 11 and the left side of the collection box 45. The inclined plate 46 is hinged on the inner wall of the collection box 45. A spring is provided between the inclined plate 46 and the bottom surface of the inner wall of the collection box 45. The arc-shaped block 47 is fixed on the top surface of the inclined plate 46. The arc-shaped block 47 is located on the movement track of the slider 21. The impurities that fall off by vibration will fall into the interior of the collection box 45. Each time the protective frame 32 moves to the left, it will squeeze the arc-shaped block 47, causing the arc-shaped block 47 to move downward. The arc-shaped block 47 drives the inclined plate 46 to move downward, and the spring between the bottom surface of the inclined plate 46 and the inner wall of the collection box 45 contracts. When the protective frame 32 moves away to the right, the arc-shaped block 47 is not squeezed. Under the action of the spring force, the inclined plate 46 will pop up upward, causing the inclined plate 46 to vibrate and loosen the impurities falling on the top surface, so that the impurities leave the discharge port at the bottom left of the box body 11 along the inclined plate 46, achieving the purpose of automatic impurity removal and improving the flexibility of impurity cleaning.

[0030] The fixing device 5 includes an elastic square rod 51, a pressing plate 52, a limiting block 53 and a metal elastic sheet 54. The elastic square rod 51 is slidably installed on the top of the containing box 23. When placing the niobium alloy on the containing box 23, the elastic square rod 51 is moved towards the middle. The pressing plate 52 is fixed at the top end of the elastic square rod 51. The niobium alloy is pressed by the pressing plate 52 to achieve the purpose of fixing the niobium alloy and prevent the niobium alloy from being thrown out during the subsequent rotation of the containing box 23. The limiting block 53 is fixed on the left side of the containing box 23. The bottom end of the elastic square rod 51 is fixed by the limiting block 53. The limiting block 53 is located on the movement track of the elastic square rod 51. When unlocking is required, pressing down the sliding block at the top end of the limiting block 53 can freely move the elastic square rod 51, making both fixing and unlocking very convenient. Both ends of the metal elastic sheet 54 are slidably installed on the bottom surface of the pressing plate 52. At the same time, the setting of the metal elastic sheet 54 makes the pressing plate 52 not directly bounce onto the niobium alloy body when fixing the niobium alloy, avoiding scratching the niobium alloy body by the pressing plate 52.

[0031] The fixing device 5 further includes a moving block 55, a chamfered block 56, a hollow square tube 57, and an adjusting pressing block 58. The moving block 55 is slidably mounted on the bottom surface of the pressing plate 52. The moving block 55 is located on the movement track of the metal elastic sheet 54. When the metal elastic sheet 54 is extruded by the niobium alloy and extends to both sides, the metal elastic sheet 54 pushes the moving block 55. The hollow square tube 57 is fixed inside the fixed end of the elastic square rod 51. The chamfered block 56 is slidably mounted on the top of the hollow square tube 57. The chamfered block 56 is located on the movement track of the moving block 55. The moving block 55 pushes and extrudes the chamfered block 56, and the chamfered block 56 moves downward and retracts into the hollow square tube 57. The adjusting pressing block 58 is slidably mounted inside the hollow square tube 57. The air in the hollow square tube 57 is extruded, and the extruded air pushes the adjusting pressing block 58 to pop out, so that the metal elastic sheet 54 and the adjusting pressing block 58 push and cooperate with each other, automatically adapting to fixedly clamp the top surface and side surface of niobium alloys of different shapes.

[0032] During use, during the annealing process, the recrystallization of grains is achieved through a certain diffusion process, and impurities may affect the diffusion rate, resulting in inconsistent grain growth in the surface and internal regions, which will affect the structural strength of the material. When the niobium alloy in the storage box 23 moves to the heating chamber, the protective frame 32 drives the semi-cylinder 44 to move to the right. During the movement of the semi-cylinder 44, it extrudes the spring-back block 42, causing the spring-back block 42 to retract into the bottom box 41. When the semi-cylinder 44 leaves, under the action of the spring force, the spring-back block 42 pops downward, and the spring-back block 42 drives the knocking block 43 to move downward, using the knocking block 43 to knock and vibrate the niobium alloy, so that the impurities on the surface of the niobium alloy fall off, achieving the purpose of cleaning impurities and improving the finished product effect of annealing. At the same time, the vibrating and falling impurities will fall into the collection box 45. When the protective frame 32 moves to the left each time, it will squeeze the arc-shaped block 47, causing the arc-shaped block 47 to move downward. The arc-shaped block 47 drives the inclined plate 46 to move downward, and the spring between the bottom surface of the inclined plate 46 and the inner wall of the collection box 45 contracts. When the protective frame 32 moves away to the right, the arc-shaped block 47 is not squeezed, and under the action of the spring force, the inclined plate 46 will pop upward, causing the inclined plate 46 to vibrate and loosen the impurities falling on the top surface, so that the impurities leave the discharge port at the left bottom of the box body 11 along the inclined plate 46, achieving the purpose of automatic impurity discharge and improving the flexibility of impurity cleaning.

[0033] When placing the niobium alloy on the storage box 23, move the elastic square rod 51 towards the middle, use the pressing plate 52 to press on the niobium alloy to achieve the purpose of fixing the niobium alloy, and avoid the niobium alloy being thrown out during the subsequent rotation of the storage box 23. Use the limit block 53 to fix the bottom end of the elastic square rod 51. When unlocking is required, press down on the sliding block at the top of the limit block 53 to freely move the elastic square rod 51, making both fixing and unlocking very convenient. At the same time, the setting of the metal elastic sheet 54 ensures that the pressing plate 52 will not directly bounce onto the niobium alloy body when fixing the niobium alloy, avoiding scratching the niobium alloy body by the pressing plate 52; when the metal elastic sheet 54 is squeezed by the niobium alloy and extends towards both sides, the metal elastic sheet 54 pushes the moving block 55, the moving block 55 pushes the extrusion chamfer block 56, the chamfer block 56 moves downward and retracts into the internal hollow square tube 57, and the air in the internal hollow square tube 57 is squeezed, and the squeezed air pushes the adjusting pressure block 58 to pop out, so that the metal elastic sheet 54 and the adjusting pressure block 58 push and cooperate with each other to automatically adapt to fix and clamp the top surface and side surface of niobium alloys with different shapes.
