Description

Technical Field

[0001] The invention relates to the technical field of laser cladding, and in particular to a stabilizer laser cladding wear-resistant belt strengthening process and processing equipment. Background Art

[0002] In the process of oil and gas drilling, drilling stabilizers are key downhole tools, mainly used to control the trajectory of the drill bit and reduce the swing of the drill string, thereby improving drilling accuracy and operation stability. However, due to long-term exposure to high temperature, high pressure, strong scouring and severe wear, the wear-resistant belt on the surface of the stabilizer is prone to peeling, pitting and local wear, affecting its service life and drilling efficiency.

[0003] At present, the industry generally uses laser cladding technology to form a high-hardness wear-resistant layer on the surface of the stabilizer to improve its wear resistance, erosion resistance and fatigue resistance. Laser cladding melts the alloy powder through a high-energy density laser beam and forms a metallurgical bonding layer on the surface of the substrate. In the laser cladding process, the use of a mixture of multiple powder materials can further optimize the performance of the cladding layer. As a heat source, the laser beam can instantly heat and melt the powder material and deposit it on the surface of the substrate to form a wear-resistant layer. When multiple powder materials are mixed, a higher performance wear-resistant layer can be achieved through the synergistic effect of different materials and the combination of their respective excellent properties.

[0004] In the prior art, multiple air pipes are usually used to transport different metal powders, or a single air pipe is used to transport premixed metal powders. When multiple air pipes are used for transportation, the gas pressure control becomes complicated due to the quality differences of different powders, and the gas pressure and flow rate need to be precisely adjusted to ensure uniform transportation. Although the use of premixed metal powder simplifies the powder transportation process, once the powder ratio is determined, it cannot be flexibly adjusted. Therefore, the prior art has certain limitations in the powder transportation process. Summary of the invention

[0029] A laser cladding wear-resistant belt processing process is applicable to any of the stabilizer laser cladding wear-resistant belt processing equipment described above, and the specific steps are as follows:

[0030] Step 1: selectively connect the feed pipes of various metal powders to the feed cavity, and the feed component extracts the metal powders in the feed pipes to enter the feed cavity;

[0031] Step 2: The conveying components work synchronously to convey the metal powder in the feed grid to the distribution grid, and apply appropriate conveying pressure to increase the density of the powder;

[0032] Step 3: The distribution component drives the distribution ring to swing, so that the distribution port rotates from the distribution grid to the air flow channel, and the metal powder in the distribution port falls into the mixing chamber under the action of gravity. At the same time, the powder delivery ratio is controlled by the limited volume of the distribution port to ensure that the various metal powders enter the mixing chamber according to the set ratio;

[0033] Step 4: The metal powder falling into the mixing chamber is disturbed by the mixing component, and air flow stirring is formed by extracting air in the air flow channel, which further promotes uniform mixing of the powder and assists the powder to enter the mixing chamber;

[0035] Step 6: Driven by airflow, the mixed metal powder is sprayed into the laser channel through multiple powder spray tubes, so that the powder enters the laser action area accurately. The spraying direction of the powder spray tube is consistent with the laser beam. The powder melts and deposits on the surface of the substrate to form a wear-resistant belt.

[0036] In summary, the present invention mainly has the following beneficial effects:

[0037] In this application, through the flexible connection of the feed pipe, operators can choose different metal powders for delivery. This design allows each powder to be flexibly adjusted. The feed component extracts the powder and distributes it to multiple feed grids. This grid design makes the collection of powder more targeted and accurate, and the powder in each grid is evenly delivered through the cooperation of the distribution component and the delivery component. In this process, through precise delivery pressure control, it is ensured that the powder maintains an appropriate density in each link, thereby avoiding the loose phenomenon that may occur during the powder delivery process in the traditional system and maintaining the uniform distribution of each powder.

[0038] When the powder enters the mixing chamber, the extraction of the airflow not only helps to mix the powder evenly, but also pushes the powder in the distribution port into the mixing chamber for even mixing through the positive pressure formed in the mixing chamber, avoiding powder backflow. It can also push the powder into the conveying chamber smoothly and spray it directionally along the powder spraying tube, so that it quickly melts and deposits on the stabilizer surface under the high temperature of the laser. This precise powder conveying control not only ensures the uniformity of the cladding layer, but also effectively improves the efficiency and quality of the cladding process. Through the mutual cooperation of the above components, the powder conveying system can flexibly respond to different working conditions and adjust according to actual needs, avoiding the limitation that the powder ratio in the traditional premixed powder method cannot be changed once it is determined. In addition, the system avoids powder agglomeration, backflow or residue during the powder conveying process, reduces the risk of equipment failure, and improves the reliability of operation.

[0039] Therefore, the design provided by this application effectively solves many problems in traditional technologies, such as difficulty in regulating airflow pressure, uneven powder delivery, and difficulty in adjusting powder ratio, through flexible powder control and precise delivery system. The system is not only easy to operate, but also can adjust the composition and ratio of powder according to actual needs, providing greater flexibility for the cladding process and further improving the performance and quality of the cladding layer.

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] refer to Figure 1-Figure 10 , a stabilizer laser cladding wear-resistant belt processing equipment, comprising:

[0058] Cladding nozzle 100;

[0059] A laser channel 101 provided on the cladding nozzle 100;

[0060] A plurality of partitions a102 are arranged in the cladding nozzle 100, and the plurality of partitions a102 separate the cladding nozzle 100 into a feed chamber 103, a distribution chamber 104, a mixing chamber 114 and a conveying chamber 105, and the plurality of chambers are arranged from top to bottom;

[0061] A plurality of feed pipes 106 provided on the cladding nozzle 100 are connected to the feed chamber 103. A plurality of partitions b107 are connected in the feed chamber 103 and the distribution chamber 104. The partitions b107 separate the feed chamber 103 into a plurality of feed grids 108. The partitions b107 separate the distribution chamber 104 into a plurality of distribution grids 109. An air flow channel 110 is formed between every two adjacent distribution grids 109.

[0062] A plurality of powder spraying tubes 111 are provided on the delivery chamber 105, the bottom ends of which face the laser beam emitted from the laser channel 101;

[0063] A distribution ring 112 is disposed in the cladding nozzle 100 , and the distribution ring 112 extends into the distribution chamber 104 . A distribution port 113 is formed on the distribution ring 112 and communicates with the distribution grid 109 .

[0064] A feeding component provided between the cladding nozzle 100 and the feeding chamber 103, used for extracting metal powder in the feeding pipe 106;

[0065] The distribution component disposed between the cladding nozzle 100 and the distribution ring 112 is used to swing the distribution ring 112. The distribution port 113 on the distribution ring 112 can rotate from the distribution grid 109 to the air flow channel 110. The distribution ring 112 intermittently swings back and forth in a predetermined path.

[0066] The conveying component provided between the feeding component and the distribution grid 109 is used to convey the metal powder in the feeding grid 108 to the distribution grid 109. The conveying component can convey the metal powder in the feeding pipe 106 to the distribution grid 109 when the feeding component extracts the metal powder, and applies conveying pressure;

[0067] The mixing component provided in the mixing chamber 114 is used to receive the metal powder falling from the air flow channel 110 and extract the air in the air flow channel 110;

[0068] By setting the feed pipe 106, when in use, the operator can connect the feed pipes of multiple metal powders to the feed pipe 106, and the laser emitted by the laser emitter can reach the surface of the stabilizer through the laser channel 101. Specifically, the metal powder is extracted by the feed component, and the metal powder is extracted into the feed chamber 103. The partition b107 forms a plurality of feed grids 108 into the feed chamber 103, and the plurality of feed grids 108 can accommodate different metal powders. In some requirements, one or more feed pipes of metal powders are selectively connected, and in other requirements, one or more feed pipes of metal powders are selectively not connected. Flexible regulation of metal powder delivery can be achieved to adapt to the changing requirements of different working conditions for the composition of the cladding layer. By selectively connecting the feed pipe 106 with the feed pipes of multiple metal powders, the type of powder entering the cladding nozzle 100 can be flexibly adjusted according to different cladding requirements, avoiding the limitations of the traditional premixing method. When the feed component extracts the metal powder in the feed pipe 106, the set conveying component and the distribution component can work synchronously. The conveying component can convey the metal powder in the feed grid 108 to the distribution grid 109, and apply appropriate conveying pressure to ensure that the metal powder enters the distribution chamber 104 evenly. The metal powder can reach the distribution port 113 on the distribution ring 112. At this time, the distribution component drives the distribution ring 112 to swing, so that the distribution port 113 originally in the distribution grid 109 reaches the air flow channel 110 with the rotation and swing of the distribution ring 112. At this time, the metal powder in the distribution port 113 can fall into the mixing chamber 114 under gravity. The limited and fixed volume of the distribution port 113 is used to accurately control the conveying ratio of the metal powder. After the metal powder falls into the mixing chamber 114, the mixing component fully stirs the powder and further promotes the uniform dispersion of different powders by extracting the air flow in the air flow channel 110. In addition, the method of extracting the air flow can also assist the powder to enter the mixing chamber 114 with the air flow, and can effectively empty the powder that swings into the air flow channel 110 with the distribution port 113 to prevent powder residue or blockage. This not only helps maintain uniform powder flow and avoid powder agglomeration, but also effectively reduces the backflow of powder during transportation. The mixed metal powder enters the conveying chamber 105 and is directed to the laser channel 101 through multiple powder spraying tubes 111 driven by the airflow. Since the spraying direction of the powder spraying tube 111 is consistent with the laser beam, the metal powder can accurately enter the laser action area, quickly melt and deposit on the stabilizer surface, thereby forming a cladding layer with uniform structure and excellent performance.

[0069] In addition, when conveying powder, the conveying component can also give a certain conveying pressure, so that the powder reaching the distribution grid 109 has a certain degree of density. This control of density helps to prevent the powder from loosening during the conveying process and ensure that each powder can maintain a stable distribution state in the distribution grid 109. By applying appropriate conveying pressure, the difference in the fluidity of the powder can be effectively reduced, ensuring that the powder is evenly distributed in each distribution grid 109. The purpose of this setting is that the quality and fluidity of different metal powders are different. In order to ensure that the powder can enter the distribution grid 109 evenly and stably and finally reach the mixing chamber 114, the density of the powder is increased by applying appropriate conveying pressure. In this way, the loosening of the powder during the conveying process can be avoided, thereby ensuring the consistency of the powder in the distribution grid 109. With the limited and fixed volume of the distribution port 113, multiple metal powders can be discharged into the mixing chamber 114 in a relatively uniform proportion. This not only ensures that each metal powder is conveyed in a consistent amount, but also improves the composition stability of the cladding layer, avoids performance fluctuations caused by uneven powder ratio, and thus improves the overall cladding quality.

[0070] Furthermore, air is drawn into the mixing chamber 114 through the mixing component, and a positive pressure is formed in the mixing chamber 114, so that the mixed powder can reach the conveying chamber 105. The conveying chamber 105 is connected with the mixing chamber 114, and a positive pressure is also generated. The formation of such positive pressure can not only effectively push the metal powder through the powder spraying tube 111 to the laser beam, but also ensure that the powder maintains a uniform flow and a stable conveying pressure during the conveying process.

[0071] As a further solution of the present invention, the feeding component includes a feeding shaft 200 rotatably connected to the feeding grid 108, the feeding shaft 200 is connected to an impeller 201 located in the feeding pipe 106, the cladding nozzle 100 is rotatably connected to a connecting pipe 202, the top of the connecting pipe 202 extends to the top of the cladding nozzle 100 and is connected to a gear a203, the top of the cladding nozzle 100 is connected to a motor 204, the driving shaft of the motor 204 is connected to a gear b205 meshing with the gear a203, the bottom of the feeding shaft 200 extends to the bottom of the feeding chamber 103 and is connected to a gear c206, and the bottom of the connecting pipe 202 is connected to a gear d207 meshing with the gear c206;

[0072] By setting the above gear transmission structure, the motor 204 drives the gear b205 to rotate, and the gear b205 drives the gear a203 to rotate, thereby transmitting power through the connecting pipe 202, so that the gear d207 meshes with the gear c206 and drives the feed shaft 200 to rotate. The rotation of the feed shaft 200 further drives the impeller 201 to rotate, so that the metal powder in the feed pipe 106 is evenly extracted and transported to the feed chamber 103 by the action of the impeller 201.

[0073] As a further solution of the present invention, the conveying component includes a conveying pipe 300 connected between the feed grid 108 and the distribution grid 109, a conveying shaft 301 is provided in the conveying pipe 300, and a spiral blade 302 located in the conveying pipe 300 is connected to the conveying shaft 301;

[0074] By providing the conveying shaft 301 and the spiral blade 302 thereon, the conveying component can rely on the pushing action of the spiral blade 302 when the conveying shaft 301 rotates, so that the metal powder in the feed grid 108 is stably conveyed to the distribution grid 109 along the direction of the conveying pipe 300. The rotation of the spiral blade 302 can not only provide a stable conveying force, but also avoid the accumulation or blockage of the powder during the conveying process, thereby improving the conveying efficiency. In addition, during the conveying process, the pushing action of the spiral blade 302 can not only stably convey the metal powder to the distribution grid 109, but also exert a certain pressure on the powder during the conveying process, so that it forms a powder flow with a certain density in the conveying pipe 300. If the powder is too loose during the conveying process, it may cause instability in the conveying amount and affect the final ratio accuracy. The continuous pushing action of the spiral blade 302 can prevent the powder from loosening, so that the density of the powder entering the distribution grid 109 remains uniform, thereby ensuring the stability of subsequent distribution and mixing.

[0075] As a further solution of the present invention, the conveying component can convey the metal powder in the material pipe to the distribution grid 109 when the feeding component extracts the metal powder;

[0076] The conveying component also includes a protective frame 303 connected to the feed grid 108, the conveying shaft 301 is rotatably connected to the protective frame 303, the feed shaft 200 is rotatably connected to the protective frame 303, and a chain transmission mechanism 304 is provided between the feed shaft 200 and the conveying shaft 301, which is located in the protective frame 303;

[0077] By setting up the protective frame 303, stable support is provided for the conveying shaft 301 and the feeding shaft 200, so that they maintain good coaxiality during operation and avoid unstable conveying caused by vibration or displacement. At the same time, the protective frame 303 can effectively reduce the transmission effect of the powder on the chain. In addition, when the feeding component extracts the metal powder, the set chain transmission mechanism 304 can allow the conveying components to operate synchronously, ensuring that the powder will not stay in the feeding grid 108 for too long, but will be quickly and evenly transported to the distribution grid 109. Doing so can ensure the stable distribution and mixing of the subsequent powder, improve the conveying efficiency, and avoid the problem of powder accumulation or flow fluctuation due to uneven feeding.

[0078] As a further solution of the present invention, the distribution component includes a driving tube 400 arranged in the cladding nozzle 100, the outer wall of the driving tube 400 is provided with a plurality of guide rails 401, the side wall of the distribution grid 109 is connected with a bracket 402, a concave-convex ring 403 is slidably connected to the bracket 402, a spring 404 is connected between the bracket 402 and the concave-convex ring 403, a guide rod 405 matched with the guide rail 401 is connected to the concave-convex ring 403, the driving tube 400 is connected to the distribution ring 112, and a pressure rod 406 in contact with the concave-convex ring 403 is connected to the bottom of the gear d207;

[0079] By setting the spring 404, the spring 404 is in an uncompressed state in the initial state and has potential energy. When the motor 204 drives the connecting tube 202 and the gear d207 to rotate to drive the conveying part and the feeding part to work, the rotation of the gear d207 can drive the multiple pressure rods 406 at the bottom thereof to make circular motions. In this process, when the pressure rods 406 reach the concave part of the concave-convex ring 403, the spring 404 releases the potential energy to allow the concave-convex ring 403 to move upward. At this time, the guide rod 405 can cooperate with the guide rail 401 to allow the driving tube 400 to rotate at a certain angle, and then the distribution ring 112 can be rotated, so that the distribution port 113 rotates with the distribution ring 112 into the air flow channel 110, so that the metal powder in the distribution port 113 falls into the air flow channel 110 under the action of gravity, and the quantitative supply of the powder is realized. When the pressure rod 406 continues to rotate and enters the raised part of the concave-convex ring 403, the spring 404 is compressed and stores elastic potential energy, so that the concave-convex ring 403 returns to its position downward, and the guide rod 405 slides in the guide rail 401, so that the drive tube 400 returns to the initial angle, driving the distribution ring 112 to rotate, so that the distribution port 113 returns to the top of the distribution grid 109, waiting for the next round of delivery. This intermittent rotation method, combined with the release and storage of the potential energy of the spring 404, enables the distribution ring 112 to stably and accurately control the delivery rhythm of the powder, avoiding the problem of excessive or insufficient powder. At the same time, since the volume of the distribution port 113 is fixed, the amount of powder delivered each time remains consistent, thereby ensuring the accurate ratio of different metal powders and improving the composition uniformity of the final cladding layer. Furthermore, by adopting a reciprocating swing method, it can be ensured that the distribution port 113 stays for a sufficient time after reaching the air flow channel 110, so that the powder can fully fall, ensuring that the amount of powder delivered each time is consistent. Furthermore, the swinging process can play a certain vibration cleaning role on the residual powder in the dispensing opening 113, ensuring that the powder can be completely released.

[0080] As a further solution of the present invention, a pressing frame 407 is connected to the concave-convex ring 403, and one end of the pressing frame 407 extends into the distribution grid 109 and is connected to a mesh plate 408;

[0081] By setting the pressing frame 407, when the concave-convex ring 403 moves downward and the driving tube 400 and the distribution ring 112 rotate through the cooperation of the guide rod 405 and the guide rail 401, the distribution port 113 is now in the distribution grid 109, and the pressing frame 407 acts on the powder synchronously, so that the powder is subjected to additional pressing force, the density of the powder is improved, and the empty space caused by loose accumulation is reduced. In this way, it can further ensure that the powder entering the distribution port 113 maintains a uniform filling state, and avoids the influence of the final ratio accuracy due to uneven density of the powder during the transportation process.

[0082] As a further solution of the present invention, a scraper 409 is connected to the distribution grid 109;

[0083] By setting the scraper 409, the height of the scraper 409 is higher than the distribution ring 112, the top surface of the distribution ring 112 contacts the bottom surface of the scraper 409, and the bottom surface of the distribution ring 112 contacts the bottom surface of the cavity of the distribution grid 109. When the distribution grid 109 rotates and swings, since the width of the distribution port 113 is greater than the thickness of the partition b107, adding the scraper 409 can ensure that when the distribution ring 112 rotates, once the distribution port 113 is connected with the air flow channel 110, the scraper 409 can close the portion of the distribution port 113 that is still in the distribution grid 109, so as to avoid the distribution grid 109 and the air flow channel 110 being temporarily connected, which affects the powder in the distribution grid 109.

[0084] As a further solution of the present invention, the mixing component includes a guide plate 500 connected to the mixing chamber 114, the bottom of the guide plate 500 is rotatably connected to a rotating ring 501, the inner wall of the rotating ring 501 is connected to a plurality of fan blades 502, and the outer wall of the cladding nozzle 100 is provided with an air inlet 503 connected to the air flow channel 110;

[0085] By setting the guide plate 500, the powder flow path entering the mixing chamber 114 can be guided so that it can reach the fan blade 502. When the rotating ring 501 rotates, the fan blade 502 is driven to rotate, so that a stable turbulent airflow is formed in the mixing chamber 114. At the same time, the air inlet 503 on the outer wall of the cladding nozzle 100 is connected to the airflow channel 110, so that the external positive pressure airflow enters the mixing chamber 114, further improving the suspension effect of the powder and preventing uneven mixing caused by rapid sedimentation of the powder due to gravity. In addition, the positive pressure airflow can continuously push the powder to move to the conveying chamber 105, and stably transport it to the laser action area through the powder spraying tube 111, ensuring the continuity and uniformity of the powder spraying.

[0086] As a further solution of the present invention, the mixing component can extract air in the air flow channel 110 when the conveying component conveys the metal powder to the distribution grid 109;

[0087] The mixing component further includes a gear e504 connected to the outer wall of the rotating ring 501, and the bottom of the conveying shaft 301 extends to the bottom of the guide plate 500 and is connected to a gear f505 meshing with the gear e504;

[0088] By setting the meshing structure of gear e504 and gear f505, the conveying shaft 301 can be rotated to convey the metal powder while driving the rotating ring 501 to rotate synchronously, so that the guide plate 500 forms a stable disturbance effect in the mixing chamber 114. In this way, while the conveying component conveys the metal powder to the distribution grid 109, the mixing component can extract the air in the airflow channel 110, so that the airflow in the mixing chamber 114 forms a negative pressure, guides the metal powder to enter the mixing chamber 114 evenly and avoids powder accumulation. In addition, with the effect of positive pressure airflow, the rotation of the fan blade 502 can further enhance the mixing effect, so that different metal powders are fully dispersed before entering the conveying chamber 105, ensure the stability of the powder ratio during powder spraying, and improve the uniformity and quality of the cladding layer. In addition, the conveying shaft 301 allows the conveying component and the mixing component to work in coordination and synchronization, so that the powder conveying process can be dynamically matched with the mixing process, ensuring that the amount of powder conveyed each time is coordinated with the airflow disturbance effect in the mixing chamber 114. It can well adapt to different powder conveying amounts.

[0089] A laser cladding wear-resistant belt processing process is applicable to any of the stabilizer laser cladding wear-resistant belt processing equipment described above, and the specific steps are as follows:

[0090] Step 1: Selectively connect the feed pipes of various metal powders to the feed chamber 103. The feed component extracts the metal powder in the feed pipe 106 and allows it to enter the feed chamber 103;

[0091] Step 2: The conveying components work synchronously to convey the metal powder in the feed grid 108 to the distribution grid 109, and apply appropriate conveying pressure to improve the density of the powder;

[0092] Step 3: The distribution component drives the distribution ring 112 to swing, so that the distribution port 113 rotates from the distribution grid 109 to the air flow channel 110. At this time, the metal powder in the distribution port 113 falls into the mixing chamber 114 under the action of gravity, and the powder delivery ratio is controlled by the limited volume of the distribution port 113 to ensure that the various metal powders enter the mixing chamber 114 according to the set ratio;

[0093] Step 4: The metal powder falling into the mixing chamber 114 is disturbed by the mixing component, and air is extracted from the air flow channel 110 to form air flow stirring, which further promotes uniform mixing of the powder and assists the powder to enter the mixing chamber 114;

[0094] Step 5: Through the vacuum effect of the mixing component, a positive pressure is formed in the mixing chamber 114, pushing the mixed powder into the conveying chamber 105. At the same time, the conveying chamber 105 is connected to the mixing chamber 114, and the whole is kept in a positive pressure state, ensuring that the powder is stably conveyed to the powder spraying tube 111;

[0095] Step 6: Driven by air flow, the mixed metal powder is sprayed to the laser channel 101 through multiple powder spraying tubes 111, so that the powder enters the laser action area accurately. Since the spraying direction of the powder spraying tube 111 is consistent with the laser beam, the powder melts and deposits on the surface of the substrate to form a wear-resistant belt.
