Description

Technical Field

[0001] This invention relates to the field of arc spraying technology, specifically to a high-performance precision pipe manufacturing spraying equipment. Background Technology

[0002] High-performance precision pipelines refer to pipelines with high standards in terms of material, dimensional accuracy, and surface performance. They are widely used in aerospace, high-end equipment manufacturing, and energy and chemical industries. These pipelines need to withstand complex working conditions such as high temperature, high pressure, and strong corrosion. Therefore, the protection performance of their inner and outer walls is extremely high. By forming a uniform and dense coating on the pipeline surface through spraying technology, the wear resistance, corrosion resistance, and high temperature resistance of the pipeline can be significantly improved, thereby extending its service life and ensuring operational safety. Therefore, special spraying equipment is an indispensable key equipment in the production process of high-performance precision pipelines. Patent CN202110666767.8 discloses an arc spraying device for the inner wall of a pipe, including an air compressor, a spraying power source, a spraying wire roll, a fixed base, a spray gun rod, and an arc spray gun connected to one end of the spray gun rod. A drive assembly is provided on one side of the fixed base. A tungsten electrode is rotatably mounted on the arc spray gun, and a wire guide assembly is provided on the tungsten electrode. The drive assembly drives the tungsten electrode to rotate inside the arc spray gun. During the rotation of the tungsten electrode, the wire guide assembly guides the spraying wire to the upper end of the tungsten electrode for heat melting. A pipe clamping assembly is provided on one side of the spray gun rod. The pipe clamping assembly is used to fix and clamp one end of the pipe and synchronously drives the clamped pipe to rotate under the action of the drive assembly. A translation support assembly is also provided below the spray gun rod. The translation support assembly provides auxiliary support for the rotating pipe and drives the pipe to translate along the direction of the spray gun rod. The wire guide assembly can guide the spraying wire when the tungsten electrode rotates, ensuring that the spraying wire can be accurately connected and heat-melted with the upper end of the tungsten electrode. The above-mentioned wire arc has low adaptability and is limited to materials that can be drawn into continuous metal wires (such as zinc, aluminum, and steel). Brittle materials (such as ceramics and high-hardness alloys) or complex multi-element alloys (such as nickel-based high-temperature alloys and metal-ceramic composites) are difficult to draw into wires and therefore cannot be used. Existing methods for using powder raw materials for arc spraying have unregulated internal pressure in the storage tank, leading to unstable material delivery, resulting in localized thinning or material breakage in the coating. This affects the uniformity and consistency of the coating, making it difficult to meet the stringent quality requirements of high-performance precision pipelines. Summary of the Invention

[0003] The purpose of this invention is to provide a high-performance precision pipe manufacturing spraying equipment to solve the following technical problems: the pressure inside the storage tank cannot be adjusted, which leads to unstable delivery of the spraying material, resulting in local thinning or material breakage of the coating, affecting the uniformity and consistency of the coating, and making it difficult to meet the stringent requirements of high-performance precision pipes for coating quality.

[0013] As a preferred embodiment of the present invention: a second spring is fixedly connected to one side of the second baffle, and the end of the second spring away from the second baffle is fixedly connected to the inside of the second fixing block; a first spring is fixedly connected to one side of the first baffle, and the end of the first spring away from the first baffle is fixedly connected to the inside of the first fixing block.

[0014] The beneficial effects of this invention are: (1) The present invention can drive the moving plate to move through the hydraulic rod, thereby driving the electric arc nozzle to rotate, thus completing the rotation coating and ensuring the uniformity of the coating. At the same time, the movement can drive the piston to rise and fall. The piston can pressurize the inside of the storage tank through the rise and fall, so that the powder can be sprayed out evenly and stably under the action of air pressure. The exhaust component can avoid the pressure inside the storage tank being too high, effectively protecting the safe operation of the spraying equipment.

[0015] (2) In this invention, the moving plate drives the gear to rotate, which in turn drives the shaft to rotate. The rotation of the shaft causes the fixed block 1 and the fixed block 2 to rotate in different directions, ensuring that one of the fixed blocks is always in the forward rotation state. Through the coordinated operation of the baffle 2, the spring 2, the baffle 1, and the spring 1, when the fixed block 1 or the fixed block 2 is in the forward rotation state, the pulley can be driven to rotate. The rotation of the pulley transmits power through the belt, ultimately driving the arc nozzle to rotate, realizing the continuous rotation of the arc nozzle, which not only improves the spraying efficiency but also ensures the uniformity and stability of the spraying.

[0016] (3) In the process of pressurizing the storage tank, the piston can drive the rotating blade to rotate. Then, the rotating plate is driven to rotate by the rotating shaft two. The rotation of the rotating plate is further driven by the cooperation of the rotating shaft three, the gear two and the gear three. This not only effectively avoids the slight agglomeration of metal powder due to static electricity or humidity during storage, ensuring that the powder particles are evenly dispersed, but also allows the components to be fully mixed, ensuring the consistency of the spraying composition, thereby significantly improving the spraying effect.

When the moving plate 22 moves, it can drive the bottom of one side of the hinge 41 to move, thereby causing the top of that side to move, which in turn causes the width of the hinge 41 to change, thus causing its height to change. The change in the height of the hinge 41 can drive the lifting block 42 to rise and fall.

[0027] Please see Figure 12 - Figure 14 As shown, a gear 2 57 is fixedly connected to the top of the rotating shaft 3 55, and a gear 3 58 is fixedly connected to the top side of the inside of the storage tank 13.

[0029] The working principle of this invention is as follows: The powder raw material is transported into the storage tank 13 through the cooperation of the conveying pipe 16, the mounting pipe 15, and the feed pipe 14. Activating the pump body 61 and pumping the powder raw material from the storage tank 13 into the arc nozzle 11 via the pump pipe 62. The arc nozzle 11 then sprays the raw material out through the nozzle 12, completing the coating process. During the coating process, the hydraulic rod 21 drives the moving plate 22 to move repeatedly. The movement of the moving plate 22 drives the gear 23 to rotate, which in turn drives the rotating shaft. The rotation of shaft 24 can drive fixed block 28 and fixed block 29 to rotate in different directions, so that one of fixed block 28 and fixed block 29 is always in the forward rotation state. Through the cooperation of baffle 20, spring 21, baffle 32 and spring 33, when fixed block 28 and fixed block 29 are rotating in the forward direction, the pulley 34 can be driven to rotate. The rotation of pulley 34 drives the arc spray pipe 11 to rotate through belt 35, thereby completing the rotation coating and ensuring the uniformity of the spray. Simultaneously, during the movement of the movable plate 22, the lifting block 42 can be raised and lowered through the hinge 41. The raising and lowering of the lifting block 42 can drive the piston 44 to rise and fall through the lifting rod 43. The piston 44 can pressurize the inside of the storage tank 13 through the raising and lowering, so that the powder can be sprayed out evenly and stably under the action of air pressure. The exhaust component 7 can prevent the pressure inside the storage tank 13 from being too high. During the pressurization process inside the storage tank 13, the rotating blade 53 can be rotated. Then, the rotating plate 54 is driven to rotate through the rotating shaft 2 52. The rotation of the rotating plate 54, through the cooperation of the rotating shaft 3 55, gear 2 57 and gear 3 58, causes the stirring blade 56 to rotate, thereby stirring the raw materials inside the storage tank 13. This not only prevents the metal powder from slightly agglomerating due to static electricity or humidity during storage, ensuring that the powder particles are evenly dispersed, but also makes the components evenly mixed, ensuring the consistency of the spraying composition, thereby improving the spraying effect.

[0030] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention.
