Description

Technical Field

[0001] This invention belongs to the field of quality inspection technology, specifically a seamless steel pipe processing quality control system. Background Technology

[0002] Seamless steel pipes have a hollow cross-section and are widely used as pipelines for transporting fluids such as oil, natural gas, coal gas, water, and certain solid materials. Compared with solid steel materials such as round steel bars, seamless steel pipes are lighter in weight while maintaining the same bending and torsional strength. Furthermore, seamless steel pipes are widely used in the manufacture of structural components and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in construction. This results in high material utilization, simplified manufacturing processes, and reduced processing time.

[0003] In existing processes, after steel pipes are formed, they are generally subjected to quality inspection, including dimensional and positional tolerances, weld quality, hole size quality, and surface quality. In addition, surface quality inspection is also required to address the issue that high-temperature impurities may adhere to the inner and outer surfaces of the steel pipe and the outer surface of the processed push rod during processing, affecting the surface quality of the steel pipe. Currently, online manual visual inspection is usually used, while offline sampling is carried out for targeted surface quality inspection using testing instruments. However, offline inspection requires changing the steel pipe station, has many clamping operations, and has limited testing functions, which affects the inspection efficiency and is very inconvenient.

Detailed Implementation

[0028] 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.

[0029] Example 1:

[0030] As shown in the attached diagram of the instruction manual. Figures 1-6 As shown, this application proposes a seamless steel pipe processing quality control system, including a processing control module, an image data acquisition module, a data analysis module, and a cleaning module. The processing control module includes a rolling assembly, a centering and guiding assembly, a drilling assembly, and a transmission control assembly. The drilling assembly includes a push rod 1 and a moving track 2. The end of the push rod 1 is provided with a push head 11. The push rod 1 is connected to a push rod trolley that is slidably mounted on the moving track 2. The push rod trolley is used to drive the push rod 1 to perform drilling processing on the steel pipe blank.

[0031] The image data acquisition module includes an image acquisition sensor, which is used to acquire image data of the inner and outer surfaces of the drilled steel pipe blank and the surface of the top rod 1. The data analysis module processes the acquired image data, extracts the feature data and analyzes it to provide data support for the adjustment of the processing parameters of the processing control module.

[0032] The cleaning module includes a chip removal box 3 symmetrically arranged on both sides of the top rod 1 on the moving track 2. A cleaning ring 4 is arranged in the gap between the chip removal boxes 3. The top rod 1 passes through the middle area of ​​the cleaning ring 4, and cleaning blocks 41 are evenly arranged on the inner surface of the cleaning ring 4. The end of the cleaning block 41 is in contact with the outer surface of the top rod 1.

[0033] The area within the gap between the cleaning blocks 41 in the inner ring surface area of ​​the cleaning ring 4 is the rinsing area 42. The inner wall of the rinsing area 42 is provided with rinsing holes 421, which are connected to the annular cavity 422 in the inner wall of the cleaning ring 4. The annular cavity 422 is connected to the liquid storage cavity 31 inside the chip removal box 3, and the annular cavity 422 is connected to the external air supply system through the air supply pipe 423.

[0034] Specific workflow: During the seamless steel pipe processing, the solid steel pipe blank is first heated to a plastic state in an annular heating furnace. Then, a center hole is machined at the end of the steel pipe blank by the centering mechanism in the centering guide assembly, preparing for the drilling process of the subsequent drilling assembly. Subsequently, the steel pipe blank is fed into the rolling assembly. The steel pipe blank is between two inclined rolls in the rolling assembly. The rolls drive the steel pipe blank to rotate and move forward. At the same time, the push rod 1 in the drilling assembly moves forward under the drive of the push rod carriage. The push head 11 at the end of the push rod 1 extends into the center hole of the steel pipe blank. Under the rolling force of the rolls and the action of the moving push rod 1, the steel pipe blank is processed into a hollow tubular structure. After processing, the push rod 1 retracts and detaches from the steel pipe blank. Then, the hollow steel pipe blank is transported to the next processing step.

[0035] During the surface quality inspection of steel pipe blanks after drilling, for the outer surface of the steel pipe blank, an image acquisition sensor can be directly deployed on the outside of the steel pipe blank on the production line to directly capture and collect image data of the outer surface. For the inner wall area of ​​the steel pipe blank that has just been drilled, a post-mounted offline endoscopic inspection method can be used. The image acquisition sensor is placed on the end of the telescopic rod device held by a robot or manually, and then inserted into the steel pipe blank to collect images. The collected image data is transmitted to the computer device in the data analysis module. After processing the image data, the surface quality features of the steel pipe are extracted. The quality recognition model obtained by deep learning is used to identify potential quality problems, such as cracks, scratches, pits, scratches, and burrs on the steel pipe surface. The location of these defects is recorded, and the possible causes are analyzed. This provides data support for the processing personnel to adjust the parameters of various processing equipment in the processing control module, such as the speed, feed, cooling lubrication, and centering accuracy. By adjusting these parameters, the probability of surface processing defects in the steel pipe is reduced, thereby improving the surface processing quality of the steel pipe.

[0036] Furthermore, in response to the possibility that metal impurities adhering to the surfaces of the drill rod 1 and the mandrel 11 used for drilling may affect the processing quality of the steel pipe, an image acquisition sensor is set up on the moving track 2 to collect image data of the moving drill rod 1 and the mandrel 11 and identify whether there are adhering metal impurities on the surface. If there are a lot of metal impurities, the cleaning module can be activated to clean the surfaces of the drill rod 1 and the mandrel 11, thereby ensuring the processing quality of the inner and outer surfaces of the steel pipe blank.

[0037] Specifically, because the push rod 1 and the push head 11 are in continuous close contact with the high-temperature steel pipe blank, the temperature of the push rod 1 rises. Therefore, a cooling channel can be set inside the push rod 1, which is connected to the coolant supply system. Cooling holes are evenly distributed on the side wall of the push rod 1. During the process of the push rod 1 moving to process the steel pipe blank and retracting to detach, the coolant supply system is activated to send coolant into the cooling channel inside the push rod 1, cooling the push rod 1 from the inside out. At the same time, coolant is sprayed out from the evenly distributed cooling holes on the outer surface of the push rod 1 and falls onto the outer surface of the push rod 1 to cool the outer surface of the push rod 1. During the drilling process of the steel pipe blank, the coolant sprayed from the cooling holes on the push rod 1 seeps outward from the gap between the push rod 1 and the central hole drilled on the steel pipe blank, which can prevent the push rod 1 from being too tightly bonded to the steel pipe blank and facilitate the detachment of the push rod 1.

[0038] During the contact process between the push rod 1 and the steel pipe blank, the high-temperature oxide scale and metal debris falling from the high-temperature steel pipe blank easily adhere to the outer surface of the push rod 1. Furthermore, due to the high temperature, these metal impurities partially melt and adhere tightly to the outer surface of the push rod 1. These tightly adhered metal impurities can easily affect the processing quality of the inner wall surface of the steel pipe blank during subsequent processing. Therefore, this application sets a cleaning ring 4 on the reciprocating movement trajectory of the push rod 1, which slides and nests on the outside of the push rod 1 to limit the push rod 1. When the push rod 1 is subjected to multiple drilling operations and the outer surface of the push rod 1 needs to be cleaned, the water pump connected to the liquid storage chamber 31 is started to pump the internal cleaning fluid into the annular cavity 422 inside the cleaning ring 4, thereby increasing the water pressure inside the annular cavity 422. This causes the flushing hole 421 to spray out a high-pressure water jet to clean the outer surface of the push rod 1 and remove the metal impurities adhering to the outer surface of the push rod 1.

[0039] Because the cleaning ring 4 extends laterally, the outflowing cleaning fluid flows laterally along the annular gap area between the cleaning ring 4 and the push rod 1. This makes the outer surface of the push rod 1 completely covered with cleaning fluid, and as the push rod 1 moves, it rubs violently against the cleaning fluid in the gap area, accelerating the removal of processing impurities adhering to the surface.

[0040] Furthermore, the cleaning blocks 41 evenly arranged on the inner surface of the cleaning ring 4 divide the gap area into multiple rinsing zones 42. When the push rod 1 moves, it causes the cleaning fluid in the rinsing zone 42 to flow and contact the cleaning blocks 41. Because the end of the cleaning block 41 is close to or even directly in contact with the outer surface of the push rod 1, the flow of the cleaning fluid is obstructed, the water pressure in the rinsing zone 42 of the gap area increases, and the penetration flow is accelerated in the gap between the end of the cleaning block 41 and the outer surface of the push rod 1. The penetration and scouring effect generated by the increased water pressure in the gap between the end of the cleaning block 41 and the outer surface of the push rod 1 promptly removes the metal impurities scraped off from the outer surface of the push rod 1 by the end of the cleaning block 41, while lubricating the contact gap and reducing the possibility of scratching the outer surface of the push rod 1.

[0041] Furthermore, the air pump in the external air supply system can be activated to send high-pressure air into the air supply system along the air supply pipe 423. The airflow mixes with the cleaning fluid inside the annular cavity 422 to form a large number of bubbles. The cleaning fluid mixed with a large number of bubbles comes into contact with the outer surface of the moving push rod 1, improving the cleaning effect on the outer surface of the push rod 1. When passing through the gap area between the end of the cleaning block 41 and the outer surface of the push rod 1, a large number of bubbles break due to pressure in the gap area. The impact of the bubble explosion can effectively peel off the tightly adhered metal debris on the outer surface of the push rod 1, while reducing damage to the outer surface of the push rod 1, thereby ensuring the processing quality of the steel pipe blanks processed by the push rod 1 in the subsequent processing.

[0042] Example 2:

[0043] Based on Embodiment 1, the cleaning ring 4 is composed of symmetrical cleaning half-rings 43. The side wall of the cleaning half-ring 43 is provided with a limiting block 45. The limiting block 45 is elastically connected to the output end of the propulsion device provided on the inner wall of the chip removal box 3. Specifically, the output end of the propulsion device can be embedded in the limiting hole on the limiting block 45. The output end and the inner wall of the limiting hole are connected by an elastic element such as a spring, so as to realize the elastic connection between the cleaning half-ring 43 and the output end of the propulsion device. The propulsion device can be an existing electric telescopic device, which can push the limiting block 45 to drive the cleaning half-ring 43 to move laterally back and forth.

[0044] Regarding how to deliver the cleaning fluid inside the storage chamber 31 into the annular cavity 422, this application provides a possible implementation scheme. Specifically, an equipment cavity 451 is provided inside the limiting block 45, and a first pipeline 452 is provided inside the equipment cavity 451. The first pipeline 452 is connected to the storage chamber 31 through a telescopic flexible hose. Then, the side wall of the first pipeline 452 is connected to the corresponding annular cavity 422 through multiple branch pipes. The air supply pipe 423 is also connected to the first pipeline 452, so as to introduce the airflow and mix it with the cleaning fluid to form a mixed state of a large number of bubbles.

[0045] Specific workflow: Based on the specific workflow in Example 1, the cleaning ring 4 can be separated or closed by the propulsion devices on both sides. This allows for flexible adjustment of the distance between the cleaning half-rings 43 that make up the cleaning ring 4 and the push rod 1. When the push rod 1 initially moves quickly away from the high-temperature steel pipe blank, the cleaning half-rings 43 on both sides can be controlled to maintain the distance between themselves and the push rod 1. The cleaning fluid released through the flushing hole 421 remotely flushes the outer surface of the push rod 1 for cooling. This is combined with the internal cooling channel to cool the push rod 1, avoiding direct contact with the push rod 1 which is still at a high temperature and causing damage to the cleaning half-rings 43. After initial cooling, the cleaning half-rings 43 on both sides are then controlled to close, flushing and scraping away the metal impurities adhering to the outer surface of the push rod 1.

[0046] The cleaning half-ring 43 is elastically connected to the corresponding propulsion device output end. In this way, the cleaning rings 4 on both sides can make a small lateral elastic movement under the vibration of the reciprocating movement of the push rod 1, which buffers the vibration impact and reduces the excessive force between the cleaning block 41 on the inner ring of the cleaning half-ring 43 and the outer surface of the push rod 1, which may lead to excessive wear at the end of the theorem block or the outer surface of the push rod 1.

[0047] Furthermore, regarding the flow of the cleaning fluid, the cleaning fluid inside the storage chamber 31 can be pumped into the first pipeline 452 through a water pump device configured inside the equipment cavity 451 and the first pipeline 452. Then, the pumped cleaning fluid is distributed to each communicating annular cavity 422 through evenly distributed branch pipes, thereby realizing the flow and distribution of the cleaning fluid.

[0048] Example 3:

[0049] Based on Embodiment 2, the cleaning block 41 has an isosceles trapezoidal cross section, and the ends of the cleaning block 41 are symmetrically provided with annular scraper blocks 411. The ends of the scraper blocks 411 are conical and contact the outer surface of the top rod 1.

[0050] The scraper blocks 411 on both sides are inclined towards each other, and the scraper blocks 411 are provided with guide grooves 412. The guide grooves 412 are connected to the annular grooves 413 between the two scraper blocks 411. The inner wall of the annular grooves 413 is evenly provided with circulation holes 414, and the circulation holes 414 are connected to the annular circulation chambers 415 inside the cleaning block 41.

[0051] The equipment cavity 451 is equipped with a second pipe 453, which is connected to the liquid storage cavity 31 via a connecting pipe. The equipment cavity 451 is equipped with a circulating water pump for the second pipe 453. A purification screen 32 is installed in the middle of the liquid storage cavity 31. The purification screen 32 is used to separate impurities in the cleaning fluid. The first pipe 452 is connected to the cleaning fluid portion filtered and purified by the purification screen 32 in the upper area. The second pipe 453 is connected to the lower area of ​​the purification screen 32, drawing the cleaning fluid mixed with solid impurities that flows into the circulation cavity 415 into the lower area of ​​the purification screen 32, so that the solid impurities are confined to the lower area of ​​the purification screen 32.

[0052] Specific workflow: Based on the specific workflow in Example 2, in the gap area formed between the push rod 1 and the inner ring of the cleaning ring 4, when the push rod 1 passes through the rinsing zone 42, the uniform rinsing holes 421 on the inner wall of the rinsing zone 42 release cleaning fluid mixed with a large number of bubbles, filling the gap area corresponding to the rinsing zone 42 and completely wrapping the outer surface of the push rod 1 in the rinsing zone 42, thereby achieving cooling and cleaning of the outer surface of the push rod 1; as the push rod 1 moves, it drives the cleaning fluid in the rinsing zone 42 to move towards the cleaning block 41; when the push rod 1 passes through the cleaning block 41, the cleaning fluid flows from the guide groove 412 on the scraper 411 into the interior of the annular groove 413, and is then drawn in by the circulation hole 414 in the annular groove 413, so that the cleaning fluid that has acted on the outer surface of the push rod 1, together with the metal impurities washed down, flows from the circulation hole 414 into the interior of the circulation chamber 415, and then flows along the connecting pipe to the lower area of ​​the purification screen 32 inside the liquid storage chamber 31. After the purification screen 32 filters out the solid impurities in the cleaning fluid, it continues to participate in the circulation flow;

[0053] The scraper 411, located at the end of the cleaning block 41 with an inclined direction opposite to the moving direction of the push rod 1, contacts the surface of the push rod 1 and thoroughly scrapes off the cleaning fluid on the surface of the push rod 1. This also scrapes off the bubble layer formed by the evaporation of the cleaning fluid on the surface of the push rod 1 due to high temperature. This ensures that the cleaning fluid in the rinsing zone 42 is fully retained in that zone and fully drawn in by the circulation hole 414, preventing it from carrying metal impurities into the next rinsing zone 42. Thus, the rinsing zone 42 on the outer surface of the push rod 1, the inner ring surface of the cleaning ring 4, and the cleaning blocks 41 on both sides form a series of cleaning units. The push rod 1 passes through each cleaning unit... After being rinsed by the cleaning fluid released from the rinsing zone 42 and scraped by the scraper 411 at the end of the cleaning block 41, the cleaning fluid that plays the rinsing role is drawn into the circulation chamber 415 by the circulation hole 414 of the same cleaning unit, thus forming a separate circulation rinsing process. In this way, the push rod 1 will go through multiple separate circulation rinsing processes as it passes through the cleaning ring 4. The metal impurities cleaned up in each circulation rinsing process will be recovered in time during that circulation rinsing process. This can reduce the situation where the cleaned metal impurities continue to flow in the gap area inside the cleaning ring 4 and re-adhere to and scrape the outer surface of the push rod 1.

[0054] Example 4:

[0055] Based on Embodiment 3, partitions 416 are uniformly arranged inside the annular groove 413. The partitions 416 are arranged in a ring around the central axis of the cleaning ring 4, and the partitions 416 are connected to the scrapers 411 on both sides, dividing the internal area of ​​the annular groove 413 into multiple connected areas 417. Circulation holes 414 are evenly distributed in each connected area 417. The guide grooves 412 are connected to the corresponding connected areas 417. The guide grooves 412 on both sides are staggered, and the guide grooves 412 on the scrapers 411 on both sides correspond to different connected areas 417.

[0056] Specific workflow: Based on the specific workflow in Embodiment 3, the partition 416 divides the internal area of ​​the annular cavity 422 into multiple connected areas 417. The guide grooves 412 on the partitions 416 on both sides are staggered, and the corresponding connected areas 417 are also staggered. When the push rod 1 moves laterally inside the cleaning ring 4, it drives the cleaning fluid in the rinsing area 42 inside a cleaning unit to flow laterally. When the cleaning fluid contacts the end of the cleaning block 41 at the end of the rinsing area 42, it first flows into the annular groove 413 from the guide groove 412 on the nearest scraper 411, and then continues... The lateral flow will be intercepted by the inclined end of the scraper 411 on the other side. When the annular groove 413 flows to both sides, it will be intercepted by the baffle 416, making it difficult for the cleaning fluid to flow to the adjacent connecting area 417 and flow from the guide groove 412 on the scraper 411 on the other side to the rinsing area 42 of the next cleaning unit. It can only be drawn in by the corresponding circulation hole 414 inside the connecting area 417 for recycling. This ensures that the rinsing fluid that has finished working on the outer surface of the push rod 1 is recycled in time within the cleaning unit, preventing metal debris from continuing to flow along the gap area and repeatedly adhering to the outer surface of the push rod 1.

[0057] Furthermore, the cross-section of the internal area of ​​the connecting region 417 is a square structure, and the end of the partition 416 is made of elastic material. When the outer surface of the push rod 1 and the connecting region 417 are pressed together and in close contact, the suction effect of the circulation hole 414 causes the interior of the connecting region 417 located in the gap area of ​​the outer surface of the push rod 1 to exhibit a negative pressure adsorption effect, which accelerates the peeling of particulate impurities adhering to the outer surface of the push rod 1.

[0058] Example 5:

[0059] Based on Embodiment 4, arc-shaped plates 44 are distributed inside the circulation cavity 415 at locations corresponding to each connecting area 417. The arc-shaped plates 44 are elastically connected to the inner wall of the circulation cavity 415, and the positioning rods provided on the arc-shaped plates 44 are slidably embedded into the positioning holes on the inner wall of the circulation cavity 415 to restrict the movement trajectory of the arc-shaped plates 44. A vibrator can be installed inside the arc-shaped plates 44, and the vibrator can be a miniature vibration motor controlled by an external controller. A tapered unblocking rod 441 is provided on the surface of the arc-shaped plates 44 at locations corresponding to the circulation holes 414, and the end of the unblocking rod 441 is slidably embedded into the circulation holes 414. Unblocking plates 442 are uniformly provided on the outer surface of the unblocking rod 441. The unblocking plates 442 are tapered, and the end of the unblocking plates 442 contacts the inner wall of the circulation holes 414.

[0060] Specific workflow: Based on the specific workflow in Example 4, to ensure the unobstructed flow of the circulation hole 414, an arc-shaped plate 44 is provided inside the circulation cavity 415. The arc-shaped plate 44 is connected to the inner wall of the circulation cavity 415 through an elastic element, and the conical unblocking rod 441 on the arc-shaped plate 44 extends into the circulation hole 414 and protrudes from the opening of the circulation hole 414 located in the connecting area 417. As the cleaning fluid flowing into the connecting area 417 is drawn out of the circulation hole 414, the cleaning fluid flows towards the inside of the circulation hole. During this process, the arc-shaped plate 44... The elastic vibration caused by the impact drives the end of the unblocking rod 441 to move repeatedly inside the circulation hole. While cleaning and unblocking the possible blockage of metal impurities inside the circulation hole 414, the tapered end of the unblocking rod 441 moves back and forth, impacting the cleaning fluid flowing into the connecting area 417. This causes the air bubbles mixed in to break due to the impact, thereby causing the outer surface of the push rod 1 and the corresponding part of the connecting area 417 to be impacted by the broken air bubbles, accelerating the peeling off of the metal impurities adhering to the surface of the push rod 1, thereby improving the cleaning efficiency of the push rod 1.

[0061] Furthermore, as the vibrator inside the arc plate 44 is activated, it drives the arc plate 44 to reciprocate along the extension trajectory of the positioning hole. When the arc plate 44 moves the unblocking rod 441 away from the circulation hole 414, the suction effect causes the connecting area 417 located in the contact gap on the outer surface of the top rod 1 to be in a negative pressure adsorption state, accelerating the peeling off of impurities adhering to the surface. When the arc plate 44 moves the unblocking rod 441 closer to the circulation hole 414, the suction effect is separated by the embedded unblocking rod 441, and at this time the negative pressure adsorption effect of the connecting area 417 on the outer surface of the top rod 1 is released. Thus, with the reciprocating movement of the arc plate 44 and the slow lateral movement of the top rod 1, the connecting area 417 repeatedly and intermittently tightly adsorbs the outer surface of the top rod 1, accelerating the peeling off of the relatively tightly adhering impurities on the outer surface of the top rod 1, improving the cleaning effect on the top rod 1, thereby ensuring the drilling quality of the subsequent seamless steel pipe.
