Description

Technical Field

[0001] This invention relates to the field of online conveying and inspection technology for forged workpieces, specifically to a forging apparatus, an online workpiece quality inspection device, and an inspection method. Background Technology

[0002] In modern forging production lines, continuous forging conveying devices such as conveyor rollers can be deployed to achieve the continuous flow of forgings. Online workpiece quality inspection systems, such as ultrasonic flaw detection, can be integrated at the conveying nodes. Through the coordinated operation of the forging conveying device and the inspection system, the quality of forgings can be efficiently determined during the flow process.

[0003] In existing technologies, when performing online ultrasonic flaw detection on forged plates using the local water immersion method, a water tank is usually set at the corresponding node of the forging conveyor for partially immersing the plates. Water is used as a coupling medium, enabling the ultrasonic probe to complete rapid flaw detection under non-contact conditions. At the same time, in conjunction with the continuous conveying of the forging conveyor, the plates are continuously inspected one by one during the transfer, realizing the coordinated operation of quality inspection and conveying.

[0004] However, the traditional method of online inspection of forged plates using a forging conveyor combined with an ultrasonic flaw detector has the following problems: Because existing fully automatic forging conveyor devices are usually designed for single standard plates to ensure feeding accuracy, it is difficult to achieve accurate docking and conveying of various types of plates when facing mixed production lines, and manual assistance and intervention are often required; when the number of plates is large, the burden of manual operation will increase significantly, thereby reducing the overall efficiency of conveying, feeding and inspection to a certain extent. Summary of the Invention

[0005] The purpose of this invention is to provide a forging device, an online workpiece quality detection device, and a detection method to solve the technical problem of insufficient conveying and feeding accuracy of multiple types of plate parts in the prior art.

[0006] The technical problem to be solved by the present invention can be achieved by the following technical solution: a forging device, including a base plate, on which plate conveying platforms are symmetrically arranged front and back; the plate conveying platform includes a fixed platform, and a lifting conveying part is provided on the fixed platform. The lifting conveying part is used to convey forging plates back and forth and to adjust the height of forging plates. An alignment adjustment part is provided on the lifting conveying part, which is used to adjust and limit the conveying position of the forging plates left and right.

[0007] Preferably, the lifting and conveying unit includes a cylinder one, which is fixedly installed on the lower side of the fixed platform. The telescopic end of the cylinder one is fixedly installed with a lifting platform that moves up and down. The lifting platform is located above the fixed platform, and multiple conveying rollers are evenly rotated on the upper side of the lifting platform. The alignment adjustment unit includes a cylinder two, which is symmetrically fixed on the upper side of the lifting platform by a support. The telescopic end of the cylinder two is fixedly installed with a connecting plate that moves left and right. Multiple guide rollers are rotatably installed on the side of the connecting plate away from the corresponding cylinder two. The guide rollers are evenly distributed back and forth and spaced apart from the conveying rollers.

[0008] An online workpiece quality inspection device includes an inspection mechanism located on the upper side of a base plate, situated between two symmetrical plate conveying platforms. The inspection mechanism, in conjunction with the plate conveying platforms, performs online ultrasonic flaw detection to inspect the quality of forged plates. The inspection mechanism comprises an immersion chamber and an ultrasonic probe. The immersion chamber partially immerses the forged plate in a coupling medium, while the ultrasonic probe extends into the coupling medium to detect local defects in the forged plate. The ultrasonic probe is located above the immersion chamber and is fixedly mounted at the lower end of an adjusting rod, which drives the ultrasonic probe to move in multiple directions for adjustment. The immersion chamber includes a water storage platform and a docking platform. The water storage platform stores the coupling medium, and docking platforms are symmetrically arranged at the front and rear. Each docking platform has a through-type interface for the forged plate to enter or leave the water storage platform. An air bladder is provided on the surface of the interface, surrounding and filling the gap between the interface and the forged plate.

[0009] Preferably, the testing mechanism further includes a storage compartment, which is vertically connected and fixedly installed below the water storage platform. The storage compartment is connected to the interior of the water storage platform, and a liquid level plate that moves vertically is slidably installed inside the storage compartment. The liquid level plate is used to control the liquid level of the coupling medium in the immersion compartment.

[0010] Preferably, a receiving groove is provided on the lower side of the interface, and a vertical moving plate that moves up and down is slidably arranged in the receiving groove. The vertical moving plate is used to adjust the vertical length and reference height of the forging plate inlet and outlet. A receiving groove is provided on the right side of the interface, and a horizontal moving plate that moves left and right is slidably arranged in the receiving groove. The horizontal moving plate is used to adjust the horizontal length of the forging plate inlet and outlet.

[0011] Preferably, a hydraulic cylinder is fixedly installed on the lower side of the storage compartment, and the telescopic end of the hydraulic cylinder is fixedly connected to the lower side of the liquid level plate. A water replenishment compartment is fixedly installed on the right side of the water storage platform. The water replenishment compartment is also used to store the coupling medium. A pipe is fixedly installed between the lower side of the water replenishment compartment and the upper right side of the storage compartment. The pipe is used to connect the water replenishment compartment and the storage compartment. A side baffle is fixedly installed on the lower right side of the liquid level plate. The side baffle is used to close the connection between the pipe and the storage compartment.

[0012] Preferably, a cylinder three is fixedly installed on the lower side of the docking platform, and the telescopic end of the cylinder three is fixedly connected to the lower side of the vertical moving plate. A receiving groove three is opened on the right side of the vertical moving plate, and the upper and right sides of the receiving groove three are open. A cylinder four is fixedly installed on the right side of the docking platform, and the telescopic end of the cylinder four is fixedly connected to the right side of the horizontal moving plate. The horizontal moving plate and the receiving groove three are slidably engaged.

[0013] Preferably, the right side of the docking interface has a through-hole that passes through the docking platform. The through-hole extends to the left and right and its upper surface is flush with the upper surface of the docking interface. The through-hole is located on the upper side of the receiving groove and is connected to the receiving groove. The surfaces of the through-hole, the docking interface, the vertical moving plate facing the docking interface, and the horizontal moving plate facing the through-hole and the docking interface are all provided with guide grooves. Adjacent guide grooves on each surface are connected to each other.

[0014] Preferably, a strip-shaped airbag is provided on the docking interface, the through-hole, the vertical moving plate, and the horizontal moving plate. The right end of the airbag extends out of the through-hole and to the right. Multiple docking balls are uniformly fixed on the side of the airbag near the docking interface, the through-hole, the vertical moving plate, and the horizontal moving plate. The docking balls slide with their corresponding guide grooves. The guide grooves cooperate with each other to guide the airbag to partially fill the gap between the forged plate and the inlet / outlet. An air pump is fixedly provided on the right side of the docking platform. The air pump is connected to the right end of the airbag through an air pipe.

[0015] An online workpiece quality inspection method includes the following steps: Inlet and outlet adjustment: When forging plates of different specifications and sizes need to be inspected, the size of the inlet and outlet formed by the vertical moving plate and the horizontal moving plate is adjusted by adjusting the vertical moving plate up and down and the horizontal moving plate left and right, so that the forging plates of the corresponding size can enter or leave the immersion tank through the inlet and outlet without contact.

[0016] Material loading: After adjusting the inlet and outlet of the immersion tank to the required size, the corresponding forging plate is adjusted up and down by the lifting conveyor to make the forging plate and the inlet and outlet at the same reference height. The forging plate is then aligned with the inlet and outlet by the alignment adjustment unit. Finally, the forging plate is continuously transported from the inlet and outlet to the immersion tank by the lifting conveyor.

[0017] Inlet / outlet sealing: When a portion of the forged plate is in the immersion chamber, the air bladder located in the gap between the inlet / outlet and the portion of the forged plate is inflated, thereby filling and sealing the gap.

[0018] Liquid level regulation: After the inlet and outlet are stably sealed by the expansion airbag, the liquid level plate is moved upward to raise the liquid level of the coupling medium in the immersion chamber until the medium completely submerges the part of the forged plate in the immersion chamber. At this time, the ultrasonic probe is inserted into the medium by the adjusting linkage to perform online detection on the part of the forged plate. After the detection is completed, the liquid level plate is moved downward until the liquid level of the medium drops below the inlet and outlet. At this time, the airbag is contracted to release the seal, so that the part of the forged plate that was not detected can enter the immersion chamber through the inlet and outlet without contact.

[0019] The beneficial effects of the present invention are as follows: The present invention, through the cooperation of the plate conveying table and the testing mechanism, can realize the automatic adjustment of the conveying position of the forged plate according to the plate model and size. The plate can be stably centered and fed into the testing device without manual intervention, thereby realizing the mixed-line conveying needs of plates of various specifications. This not only significantly reduces the burden of manual operation, but also effectively improves the overall efficiency of conveying, feeding and testing. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1 Please see Figures 1 to 14 A forging apparatus includes a base plate 1, on which a plate conveying platform 2 is symmetrically arranged front and back; the plate conveying platform 2 includes a fixed platform 21, which is fixedly arranged on the upper side of the base plate 1 by a plurality of support columns. A lifting conveying part 22 is provided on the fixed platform 21, which is used to convey forging plates back and forth and to adjust the height of forging plates. An alignment adjustment part 23 is provided on the lifting conveying part 22, which is used to adjust and limit the conveying position of the forging plates left and right.

[0037] Please see Figure 2 and Figure 3The lifting and conveying unit 22 includes a cylinder 221, which is fixedly mounted on the lower side of the fixed platform 21. The telescopic end of the cylinder 221 slides vertically through the fixed platform 21. A lifting platform 222 that moves vertically is fixedly mounted on the telescopic end of the cylinder 221. The lifting platform 222 is located above the fixed platform 21 and is U-shaped with its opening facing upwards. Multiple guide rods 1 that are slidably connected to the fixed platform 21 are fixedly mounted on the lower side of the lifting platform 222. Multiple conveying rollers 223 are evenly rotated back and forth on the upper side of the lifting platform 222. The conveying rollers 223 are subjected to external... A drive motor (not shown in the figure) drives the forging plate to be conveyed back and forth; the alignment adjustment part 23 includes a second cylinder 231. The second cylinder 231 is symmetrically fixed on the upper side of the lifting platform 222 by a support. The telescopic end of the second cylinder 231 slides through the corresponding support. The telescopic end of the second cylinder 231 is fixedly provided with a connecting plate 232 that moves left and right. Multiple guide rollers 233 are rotatably provided on the side of the connecting plate 232 away from the corresponding second cylinder 231. Each guide roller 233 is evenly distributed back and forth and spaced apart from the conveying roller 223.

[0038] When conveying forged plates of different sizes, cylinder 221 drives the lifting platform 222 to move up and down. The lifting platform 222 then drives the conveying roller 223 and the forged plate on its upper side to move synchronously to adjust the forged plate to the required height position. Then, cylinder 231 drives the corresponding connecting plate 232 and the guide roller 233 on it to move left and right, so that the guide rollers 233 on the left and right sides are stably attached to the corresponding edges of the forged plate, so that the guide rollers 233 guide the forged plate to move back and forth stably, and the guide rollers 233 drive the forged plate to move left and right synchronously to adjust it to the required position. At this time, the external drive motor can drive the conveying roller 223 to directionally convey the forged plate.

[0039] The above operation method can automatically adjust the conveying position of the forged plates according to the plate model and size, and can stably center the plates and feed them into the testing device without manual intervention. This can meet the mixed-line conveying needs of plates of various specifications, which not only significantly reduces the burden of manual operation, but also effectively improves the overall efficiency of conveying, feeding and testing.

[0040] Example 2 Please see Figures 1 to 14An online workpiece quality inspection device is disclosed. A detection mechanism 3 is installed on the upper side of a base plate 1, located between two symmetrical plate conveying platforms 2. The detection mechanism 3 is used to cooperate with the plate conveying platforms 2 for online ultrasonic flaw detection of forged plates. The detection mechanism 3 includes an immersion chamber and an ultrasonic probe 31. The immersion chamber is fixedly installed on the upper side of the base plate 1 by multiple support pillars. The immersion chamber is used to partially immerse the forged plate in a coupling medium. The ultrasonic probe 31 is used to extend into the coupling medium to detect local defects in the forged plate. The ultrasonic probe 31 is located above the immersion chamber and is fixedly installed at the lower end of an adjusting rod. The adjusting rod is used to drive the ultrasonic probe 31 to move and adjust in multiple directions.

[0041] Please see Figure 4 , Figure 5 and Figure 6 The immersion chamber includes a water storage platform 32 and a docking platform 33. The water storage platform 32 is used to store the coupling medium. The docking platform 33 is symmetrically fixed at the front and back of the water storage platform 32. The docking platform 33 has a through-port 34 for the forging plate to enter or leave the interior of the water storage platform 32. The inlet and outlet of the immersion chamber are located inside the docking platform 34. An air bladder 35 is provided on the surface of the docking platform 34. The air bladder 35 surrounds and wraps around a part of the forging plate. The air bladder 35 is used to expand and fill the gap between the inlet and outlet of the docking platform 34 and the part of the forging plate.

[0042] When the forged plate, whose position has been adjusted, is partially transported into the immersion chamber via the plate conveyor 2, a certain safety gap must be reserved at the inlet and outlet of the immersion chamber to prevent the plate from jamming or being scratched. Therefore, when the plate is partially and completely immersed in the coupling medium, the coupling medium in the immersion chamber will continuously leak out through the safety gap. At the same time, in order to ensure that the continuous coupling between the ultrasonic probe 31 and the plate is not affected, the medium needs to be continuously replenished into the immersion chamber. The medium fluctuations caused by the continuous loss and replenishment of the medium in the immersion chamber will continuously lead to relatively obvious thickness fluctuations and flow velocity gradients in the medium between the ultrasonic probe 31 and the plate, thereby interfering with the stability of ultrasonic detection and the accuracy of scanning imaging. By making the plate from the interface The inlet and outlet of the interface 34 enter the water storage platform 32 without contact to avoid jamming or scratching of the plate. When the part of the plate to be tested is stably placed in the water storage platform 32 and completely submerged in the coupling medium, the air bladder 35 is inflated to completely seal and fill the gap between the inlet and outlet of the interface 34 and the plate. This prevents the medium from continuously leaking out through the gap between the inlet and outlet and the plate. At the same time, it is no longer necessary to continuously replenish the medium into the immersion chamber when the adjusting rod drives the ultrasonic probe 31 to move and test the plate. Thus, during the local quality inspection of the plate, the stability and uniformity of the coupling medium between the ultrasonic probe 31 and the plate are ensured, as well as the stability of ultrasonic detection and the accuracy of scanning imaging.

[0043] Example 3 Please see Figure 5 and Figure 7 The detection mechanism 3 also includes a storage chamber 36, which is vertically connected inside. The storage chamber 36 is fixedly installed on the lower side of the water storage platform 32 and is connected to the interior of the water storage platform 32. A liquid level plate 361 that moves vertically is slidably installed inside the storage chamber 36. The liquid level plate 361 is slidably sealed with the storage chamber 36 and is used to control the liquid level of the coupling medium in the immersion chamber.

[0044] Please see Figure 5 and Figure 7 A hydraulic cylinder 362 is fixedly installed on the lower side of the storage compartment 36 via a fixing plate. The telescopic end of the hydraulic cylinder 362 slides up and down through the fixing plate. The telescopic end of the hydraulic cylinder 362 is fixedly connected to the lower side of the liquid level plate 361. A water replenishment compartment 363 with an open upper end is fixedly installed on the right side of the water storage platform 32. The water replenishment compartment 363 is also used to store the coupling medium. A pipe is fixedly installed between the lower side of the water replenishment compartment 363 and the upper right side of the storage compartment 36. The pipe is used to connect the water replenishment compartment 363 and the storage compartment 36. A side baffle 364 is fixedly installed on the lower right side of the liquid level plate 361. The side baffle 364 is used to close the connection between the pipe and the storage compartment 36.

[0045] Because the coupling medium continues to leak from the inlet and outlet of the immersion tank even when the plate is not within the inlet / outlet or when the plate moves relative to the inlet / outlet, the coupling medium needs to be continuously replenished into the immersion tank. This causes fluctuations in the medium over a certain period of time, and also slows down the overall conveying and flaw detection efficiency of the plate. The hydraulic cylinder 362 drives the level plate 361 to gradually move downwards along the receiving tank 36, allowing the coupling medium in the water storage platform 32 to gradually enter the receiving tank 36. The liquid level in the water storage platform 32 gradually decreases until it drops below the inlet / outlet. At this point, even if the inlet / outlet... With the inlet open and gap present, the coupling medium located below the inlet and outlet of the immersion chamber will not leak out through the inlet and outlet. When the part to be tested is stably located in the water storage platform 32 and the inlet and outlet are sealed by the expansion of the air bladder 35, the hydraulic cylinder 362 can drive the liquid level plate 361 to move upward gradually, so that the coupling medium in the storage chamber 36 can be gradually input into the water storage platform 32. This will cause the liquid level of the medium in the water storage platform 32 to rise rapidly, efficiently and steadily until the part to be tested is completely submerged in the coupling medium. At this time, the ultrasonic probe 31 can be driven by the adjusting rod to continue to perform online quality inspection on the part.

[0046] Because a small amount of coupling medium adheres to the surface of the plate leaving the immersion tank, the coupling medium in the immersion tank is gradually consumed. As the liquid level plate 361 moves the side baffle 364 downward, the replenishment tank 363 is connected to the storage tank 36 through the pipe. Since the liquid level in the replenishment tank 363 is higher than the gradually decreasing liquid level in the storage platform 32, the coupling medium in the replenishment tank 363 is gradually replenished into the storage platform 32 in small amounts and slowly under the action of gravity. This achieves almost fluctuation-free replenishment of the medium in the storage platform 32, which not only avoids the continuous loss of the medium in the storage platform 32, but also ensures the continuous stability and uniformity of the medium in the storage platform 32.

[0047] Example 4 Please see Figure 6 , Figure 8 , Figure 9 and Figure 10 The interface 34 has a receiving groove 331 on its lower side. A vertical moving plate 333 that moves up and down is slidably disposed in the receiving groove 331. The vertical moving plate 333 is slidably sealed with the receiving groove 331. The vertical moving plate 333 is used to adjust the vertical length and reference height of the forging plate inlet and outlet. The interface 34 has a receiving groove 332 on its right side. A horizontal moving plate 336 that moves left and right is slidably disposed in the receiving groove 332. The horizontal moving plate 336 is slidably sealed with the receiving groove 332. The horizontal moving plate 336 is used to adjust the horizontal length of the forging plate inlet and outlet.

[0048] Please see Figures 10 to 13 A cylinder 335 is fixedly installed on the lower side of the docking platform 33. The telescopic end of the cylinder 335 is fixedly connected to the lower side of the vertical moving plate 333. A receiving groove 334 is opened on the right side of the vertical moving plate 333. The upper and right sides of the receiving groove 334 are open. A cylinder 437 is fixedly installed on the right side of the docking platform 33. The telescopic end of the cylinder 437 is fixedly connected to the right side of the horizontal moving plate 336. The upper and left surfaces of the docking interface 34, the upper surface of the vertical moving plate 333, and the left surface of the horizontal moving plate 336 together form the inlet and outlet of the forging plate.

[0049] Because the forged plates conveyed by the plate conveyor 2 may vary greatly in size, and the fixed-size inlet and outlet cannot allow larger plates to pass through without contact, and the airbags 35 at the inlet and outlet cannot seal gaps beyond their expansion range, the inspection mechanism 3 cannot cooperate with the plate conveyor 2 to perform online inspection of a wide range of plate types. By using cylinder 335 to drive the vertical moving plate 333 to move up and down along the receiving groove 331, the vertical distance between the inlet and outlet is adjusted. By using cylinder 437 to drive the horizontal moving plate 336 to move left and right along the receiving groove 332, the horizontal distance between the inlet and outlet is adjusted. This allows for rapid adjustment of the size of the inlet and outlet, ensuring that the gap between the inlet and outlet and the plate is within a reasonable range. It also ensures that the expanding airbags 35 in the inlet and outlet can stably fill and seal the gap, thereby guaranteeing the applicability of the inspection mechanism 3 and the reliability of the airbags 35 in sealing the inlet and outlet.

[0050] When inspecting the end of the forged plate, the end of the plate is only inserted into the inlet / outlet on one side of the immersion chamber, and not into the inlet / outlet on the other side. As a result, the idle inlet / outlet continues to leak media. The idle inlet / outlet can be adjusted to its minimum state by moving the vertical moving plate 333 and the horizontal moving plate 336, and the air bladder 35 in the inlet / outlet can be expanded to its maximum range to completely close the idle inlet / outlet. This ensures that even when the inlet / outlet on one side is idle and the end of the forged plate needs to be inspected, the continuous leakage of media can still be stably prevented.

[0051] If the reference height of the inlet and outlet remains unchanged, when adapting to plates of higher height, the total amount of coupling medium in the immersion chamber needs to be increased to raise the liquid level and stably immerse the plates. However, increasing the total amount of medium will significantly increase the operating load of the hydraulic cylinder 362 adjusting the height of the liquid level plate 361. By moving the vertical moving plate 333 downward, not only can the vertical distance between the inlet and outlet be increased to adapt to plates of higher height, but the reference height of the inlet and outlet can also be lowered simultaneously. Thus, stable immersion of plates of higher height can be achieved without increasing the total amount of medium in the immersion chamber.

[0052] Please see Figures 8 to 11 The right side of the interface 34 is provided with an outlet 338 that passes through the docking platform 33. The outlet 338 extends to the left and right and its upper surface is flush with the upper surface of the interface 34. The outlet 338 is located above the receiving groove 332 and is connected to the receiving groove 332. The surfaces of the outlet 338, the interface 34, the vertical moving plate 333 facing the interface 34, and the horizontal moving plate 336 facing the outlet 338 and the interface 34 are all provided with guide grooves 339. The adjacent corresponding guide grooves 339 on each surface are connected to each other.

[0053] Please see Figures 12 to 14A strip-shaped airbag 35 is provided on the interface 34, the outlet 338, the vertical moving plate 333, and the horizontal moving plate 336. The right end of the airbag 35 extends out of the outlet 338 and to the right. A plurality of docking balls 351 are evenly fixed on the side of the airbag 35 near the interface 34, the outlet 338, the vertical moving plate 333, and the horizontal moving plate 336. The docking balls 351 slide with their respective guide grooves 339. The guide grooves 339 cooperate with each other to guide the partial filling of the gap between the forged plate and the inlet / outlet of the airbag 35. An air pump 352 is fixed on the right side of the docking platform 33. The air pump 352 is connected to the right end of the airbag 35 through an air pipe. The air pump 352 can deliver gas into the airbag 35 or extract gas from the airbag 35, which can make the airbag 35 expand or contract rapidly.

[0054] When the vertical moving plate 333 and the horizontal moving plate 336 are adjusted, the vertical moving plate 333 or the horizontal moving plate 336 moves synchronously through the guide groove 339, driving the sliding docking balls 351 inside to move synchronously. This is coordinated with manual synchronous control adjustment of the right end of the airbag 35, so that the portion of the right end of the airbag 35 extending from the outlet 338 is simultaneously pulled into or pushed out of the docking interface 34 through the docking balls 351. Furthermore, the guide groove 339 guides the docking balls 351 on the airbag 35, ensuring that the portion of the airbag 35 located within the docking interface 34 is stably positioned on the inlet / outlet surface (e.g., the surface formed by the docking interface 34, the vertical moving plate 333, and the horizontal moving plate 336). Figure 14 As shown in the figure, when the forged plate is partially inside the inlet and outlet, the airbag 35 can stably surround the periphery of the plate and fill the gap between the inlet and outlet and the forged plate through expansion; wherein, when the airbag 35 expands, the airbag 35 also seals the receiving groove 334 on the vertical moving plate 333, the gap between the upper side of the horizontal moving plate 336 and the interface 34, the outlet 338, and each guide groove 339, thereby preventing the medium from seeping in or being lost.

10. A method for online inspection of workpiece quality, characterized in that, The online workpiece quality inspection device as described in claim 5 includes the following steps: Inlet and outlet adjustment: When forging plates of different specifications and sizes need to be inspected, the size of the inlet and outlet formed by the vertical moving plate and the horizontal moving plate is adjusted by adjusting the vertical moving plate up and down and the horizontal moving plate left and right, so that the forging plates of the corresponding size can enter or leave the immersion tank through the inlet and outlet without contact. Material loading: After adjusting the inlet and outlet of the immersion tank to the required size, the corresponding forging plate is adjusted up and down by the lifting conveyor to make the forging plate and the inlet and outlet at the same reference height. The forging plate is then aligned with the inlet and outlet by the alignment adjustment unit. Finally, the forging plate is continuously conveyed from the inlet and outlet to the immersion tank by the lifting conveyor. Inlet and outlet sealing: When a part of the forged plate is in the immersion chamber, the air bladder in the gap between the inlet and outlet and the part of the forged plate is inflated and then the inflated air bladder fills and seals the gap. Liquid level regulation: After the inlet and outlet are stably sealed by the expansion airbag, the liquid level plate is moved upward to raise the liquid level of the coupling medium in the immersion chamber until the medium completely submerges the part of the forged plate in the immersion chamber. At this time, the ultrasonic probe is inserted into the medium by the adjusting linkage to perform online detection on the part of the forged plate. After the detection is completed, the liquid level plate is moved downward until the liquid level of the medium drops below the inlet and outlet. At this time, the airbag is contracted to release the seal, so that the part of the forged plate that was not detected can enter the immersion chamber through the inlet and outlet without contact.
