Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel polishing, and more specifically, to a high-brightness stainless steel surface treatment device and a treatment method. Background Technique

[0002] Sandblasting and polishing is a treatment method used to improve the brightness and smoothness of the stainless steel surface. Sandblasting and polishing utilizes compressed air to spray abrasive materials (such as alumina, silicon carbide, etc.) onto the stainless steel surface at high speed. Through the impact and friction of the abrasive materials on the surface, impurities, oxide scales, and micro-scratches on the surface are removed. At the same time, a uniform micro-concave and convex structure is formed on the surface, thereby achieving the effects of polishing and increasing brightness. This micro-concave and convex structure can effectively scatter light, reduce diffuse reflection, and make the stainless steel surface present a high-brightness appearance.

[0003] However, during the existing stainless steel sandblasting treatment, the spraying direction is mostly fixed, the sandblasting mode is single, and the nozzle type is fixed. It is difficult to quickly switch the sandblasting mode of sand output, resulting in difficulties in meeting the diversified high-brightness sandblasting requirements that need to take into account vertical surfaces and flat surfaces, as well as fine textures or large-area sandblasting, and it is difficult to meet the high-precision sandblasting and polishing requirements. As a result, the sandblasting effect on the workpiece surface is uneven. Especially when processing high-brightness stainless steel, local over-sandblasting or missed sandblasting is likely to occur, affecting the surface smoothness and quality stability. In view of this, we propose a high-brightness stainless steel surface treatment device and a treatment method. Summary of the Invention

[0025] A high-brightness stainless steel surface treatment method includes the following steps:

[0026] S1. Equipment startup and state switching: Place the stainless steel workpiece on the work station, check the sand material of the sandblasting machine body, turn on the equipment, and adjust the pressure; then switch the sandblasting state according to the requirements: Drive the turntable by starting the first motor to connect the connecting hose with the vertical spraying connecting pipe and enter the vertical spraying state; or connect the horizontal spraying connecting pipe and enter the horizontal spraying state;

[0032] S3. Finishing and inspection; After sandblasting is completed, turn off the equipment, switch the system back to the initial state, remove the workpiece, clean the residual abrasive material impurities, check the sandblasting effect, if there are problems, reprocess or remedy, and finally place the workpiece waiting for the subsequent process.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. The present invention can be flexibly switched between vertical spraying and horizontal spraying as needed through the adjustable conveying component, which has great advantages in processing high-brightness stainless steel. The vertical spraying precisely polishes the vertical surface, and the horizontal spraying evenly processes the plane, making the sandblasting effect uniform. The vertical spraying component can freely switch between the round nozzle and square nozzle sandblasting states. The round nozzle sandblasting creates fine textures without damaging the high-brightness surface layer, achieving precise polishing; the square nozzle sandblasting efficiently covers a large area of the plane, meeting the sandblasting requirements of various patterns. The present invention enables the sandblasting machine to adapt to complex high-brightness stainless steel sandblasting and polishing tasks through a multi-state and multi-mode adjustable sandblasting system.

[0035] 2. The present invention adopts a rotary disc type switching structure. Traditional sandblasting equipment relies on multiple valves to independently control the on-off of pipelines. During operation, different valves need to be frequently opened and closed. However, the rotary disc of the present invention is precisely driven by the first motor, and the connecting hose rotates synchronously through mechanical linkage, realizing one-key switching between the vertical spraying connecting pipe and the horizontal spraying connecting pipe. Compared with the traditional valve operation, the operation efficiency is improved. At the same time, the design of the close fit between the rotary disc and the fixed disc uses surface sealing to replace traditional point sealing, reducing the risk of abrasive material leakage and avoiding local over-corrosion or uneven sandblasting on the surface of high-brightness stainless steel caused by sand leakage. The present invention replaces the traditional valve control by setting a rotary disc type switching structure, improving the operation efficiency and reducing the risk of abrasive material leakage.

[0036] 3. Through the variable flow guiding structure of the present invention, when the third motor starts, the power is transmitted to the fourth bevel gear through the third bevel gear, the driving rod drives the driving cam to rotate, and the driving cam fits with the lifting ring. As it rotates, the lifting ring slides up and down on the circular nozzle. When the lifting ring slides upward, the connecting rope is pulled, and the flow guiding plate rotates around the hinge under the action of the connecting rope, and the torsion reset part is deformed by force. At this time, the angle of the flow guiding plate changes, and the spraying direction and range of the abrasive can be adjusted, so that the abrasive acts more precisely on a specific area of the stainless steel surface, meeting the requirements of complex shapes and fine processing. When the driving cam rotates in the opposite direction, the lifting ring descends, the torsion reset part restores its deformation, and drives the flow guiding plate back to the initial position, facilitating the next adjustment. By designing the variable flow guiding structure, the present invention enables the circular nozzle to flexibly change the spraying path of the abrasive according to actual needs during vertical spraying, effectively improving the sandblasting effect and quality.

[0037] 4. Through the angle adjustment structure of the present invention, also driven by the third motor, another set of driving rods drives the driving wheel to rotate, and the driving wheel fits with the transmission ring. When the driving wheel rotates, it drives the transmission ring to rotate, and the transmission ring is installed outside the square nozzle, thereby realizing the angle adjustment of the square nozzle. When performing vertical spraying on stainless steel, according to the shape, size of the workpiece and the different sandblasting parts, the spraying angle of the square nozzle can be flexibly changed, so that the abrasive can impact the stainless steel surface at the best angle, enhancing the sandblasting effect. Through the angle adjustment structure of the present invention, whether sandblasting on a vertical surface, an inclined surface or a surface with a special angle, the angle adjustment structure can ensure the precise positioning of the square nozzle, improving the pertinence and effectiveness of sandblasting.

[0038] 5. By adopting a circumferential pipeline structure for the flat spraying pipeline of the present invention, when the abrasive flows in the circumferential pipeline, it will continuously collide and mix, so that the speed and density of the abrasive are more uniform. When the abrasive reaches the flat spraying flat mouth, it can be sprayed out in a more stable and uniform state, ensuring that the sandblasting effect on the stainless steel plane is more consistent. The flat spraying flat mouth is installed at the outlet end of the flat spraying pipeline, and the narrow and long cross-sectional shape of the flat mouth compresses the abrasive beam into a flat fan shape, and the coverage area is larger than that of a circular nozzle. A wider plane area can be processed by a single spraying. Through the circumferential pipeline structure and the flat spraying flat mouth of the present invention, when polishing a high-brightness stainless steel plane, a uniform sandblasting texture is formed, increasing the sandblasting coverage area.

[0064] Example 1:

[0065] As Figures 1 to 9 shown, a high-brightness stainless steel surface treatment device and treatment method according to the present invention include a sandblasting machine body 1 and an adjustable sandblasting system 2 connected to the output end of the sandblasting machine body 1;

[0066] The adjustable sandblasting system 2 has a vertical spray state and a flat spray state, and includes an adjustable conveying component 3, a vertical spray component 4 and a flat spray component 5; when the adjustable sandblasting system 2 is in the vertical spray state, the adjustable conveying component 3 connects the vertical spray component 4 with the sandblasting machine body 1 for vertical spraying work on stainless steel; when the adjustable sandblasting system 2 is in the flat spray state, the adjustable conveying component 3 connects the flat spray component 5 with the sandblasting machine body 1 for flat spraying work on stainless steel.

[0067] The vertical spray component 4 has a round nozzle sandblasting state and a square nozzle sandblasting state, and includes a nozzle conversion structure 401, a round nozzle sandblasting structure 402 and a square nozzle sandblasting structure 403; when the vertical spray component 4 is in the round nozzle sandblasting state, the nozzle conversion structure 401 drives the round nozzle sandblasting structure 402 to communicate with the adjustable conveying component 3 for circular sandblasting work on stainless steel; when the vertical spray component 4 is in the square nozzle sandblasting state, the nozzle conversion structure 401 drives the square nozzle sandblasting structure 403 to communicate with the adjustable conveying component 3 for square sandblasting work on stainless steel.

[0068] The present invention can be flexibly switched between vertical spraying and horizontal spraying as needed through the adjustable conveying component 3, and has great advantages when processing high-brightness stainless steel. The vertical spraying precisely polishes the vertical surface, and the horizontal spraying evenly processes the plane, making the sandblasting effect uniform. The vertical spraying component 4 can freely switch between the round nozzle and square nozzle sandblasting states. The round sandblasting creates fine textures without damaging the high-brightness surface layer, achieving precise polishing; the square sandblasting efficiently covers a large area of the plane, meeting the sandblasting requirements for various patterns. Through the adjustable sandblasting system 2 with multiple states and multiple modes, the sandblasting machine of the present invention can adapt to complex high-brightness stainless steel sandblasting and polishing tasks.

[0069] Specifically, as Figures 3 to 7 shown, the adjustable conveying component 3 involved in the present invention includes a sandblasting housing 301, a first motor 302, a turntable 303, a connecting hose 304, a fixed disk 305, a vertical spraying connecting pipe 306, and a horizontal spraying connecting pipe 307; the first motor 302 is installed inside the sandblasting housing 301, the turntable 303 is installed at the output end of the first motor 302, and the turntable 303 is rotatably connected inside the sandblasting housing 301. Two connecting hoses 304 are connected to both sides of the turntable 303, and the two connecting hoses 304 are connected to the output end of the sandblasting machine body 1. The fixed disk 305 is installed inside the sandblasting housing 301 and is attached to one side of the turntable 303. Two vertical spraying connecting pipes 306 are installed on both sides of the fixed disk 305 along the diameter direction, and two horizontal spraying connecting pipes 307 are installed on the other set of diameter directions perpendicular to the fixed disk 305. The turntable 303 is used to switch the two connecting hoses 304 between the states of connecting the two vertical spraying connecting pipes 306 and the two horizontal spraying connecting pipes 307.

[0070] Through the turntable 303 type switching structure of the present invention, traditional sandblasting equipment relies on multiple valves to independently control the on-off of pipelines. During operation, different valves need to be frequently opened and closed. However, the turntable 303 of the present invention is precisely driven by the first motor 302, and the connecting hose 304 is synchronously rotated through mechanical linkage, realizing one-key switching between the vertical spraying connecting pipe 306 and the horizontal spraying connecting pipe 307, improving the operation efficiency compared with traditional valve operations. At the same time, the design of the turntable 303 closely fitting with the fixed disk 305 uses surface sealing instead of traditional point sealing, reducing the risk of sand material leakage and avoiding local over-corrosion or uneven sandblasting on the surface of high-brightness stainless steel caused by sand leakage. By setting the turntable 303 type switching structure to replace the traditional valve control, the operation efficiency of the present invention is improved, and the risk of sand material leakage is reduced.

[0071] It is worth noting that, as Figures 8 to 10As shown in the figure, the nozzle conversion structure 401 of the present invention includes a second motor 4011, a first bevel gear 4012, a second bevel gear 4013, and a mounting disc 4014; the second motor 4011 is installed in the sandblasting housing 301, the first bevel gear 4012 is installed at the output end of the second motor 4011, the second bevel gear 4013 is meshed and connected below the first bevel gear 4012, and the mounting disc 4014 is installed inside the second bevel gear 4013.

[0072] The round nozzle sandblasting structure 402 includes a round nozzle 4021, and the square nozzle sandblasting structure 403 includes a square nozzle 4031; the round nozzle 4021 is a cylindrical structure provided with a through cylindrical groove, the longitudinal section of the square nozzle 4031 is circular, and a rectangular opening is provided at the bottom end; the round nozzle 4021 is installed on both sides of the mounting disc 4014 along the diameter direction, and two square nozzles 4031 are rotatably connected on the other set of diameter directions perpendicular to the mounting disc 4014. The mounting disc 4014 is used to switch the two vertical spray connecting pipes 306 between the states of connecting the two round nozzles 4021 and the two square nozzles 4031.

[0073] In the present invention, through the nozzle conversion structure 401, when traditional sandblasting equipment switches different-shaped nozzles, it needs to be manually disassembled and installed, which not only takes a long time but also has the risk of poor sandblasting effect due to improper installation. In the present invention, the second motor 4011 drives the first bevel gear 4012 to rotate, and the power is transmitted to the mounting disc 4014 through the meshed second bevel gear 4013, so that the mounting disc 4014 rotates smoothly. During this process, the mounting disc 4014 drives the round nozzle 4021 and the square nozzle 4031 to switch, without manual intervention, and the conversion between the round nozzle sandblasting structure 402 and the square nozzle sandblasting structure 403 can be completed in only a few seconds.

[0074] Further, as Figures 10 to 14 shown in the figure, the vertical spray assembly 4 of the present invention further includes a driving structure 404, and the driving structure 404 includes a third motor 4041, a third bevel gear 4042, a fourth bevel gear 4043, and a driving rod 4044; the third motor 4041 is installed at the top end of the mounting disc 4014, the third bevel gear 4042 is installed at the output end of the third motor 4041, and the third bevel gear 4042 is located inside the mounting disc 4014. Four fourth bevel gears 4043 are meshed and connected equidistantly in a ring above the third bevel gear 4042, and four driving rods 4044 are respectively installed on one side of the four fourth bevel gears 4043.

[0075] The vertical spraying assembly 4 further includes a variable flow guiding structure 405, which includes a driving cam 4051, a lifting ring 4052, a connecting rope 4053, a flow guiding plate 4054, a hinge 4055, and a torsion resetting member 4056; two driving cams 4051 are installed at the ends of a set of driving rods 4044, the driving cam 4051 is attached to the lifting ring 4052, the lifting ring 4052 is slidably connected to a circular nozzle 4021, six connecting ropes 4053 are connected to the lifting ring 4052 at equal intervals in a ring shape, and the six connecting ropes 4053 penetrate into the circular nozzle 4021, and the other ends of the six connecting ropes 4053 are respectively connected to the lower sides of the six flow guiding plates 4054, the flow guiding plate 4054 is rotatably connected to the hinge 4055, the torsion resetting member 4056 is arranged between the flow guiding plate 4054 and the hinge 4055, and the torsion resetting member 4056 is connected between the flow guiding plate 4054 and the hinge 4055.

[0076] The vertical spraying assembly 4 further includes an angle adjustment structure 406, which includes a driving wheel 4061 and a transmission ring 4062; two driving wheels 4061 are installed at the ends of another set of driving rods 4044, the driving wheel 4061 is attached to the top of the transmission ring 4062, and the transmission ring 4062 is installed outside the square nozzle 4031.

[0077] In the present invention, through the variable flow guiding structure 405, when the third motor 4041 is started, the power is transmitted to the fourth bevel gear 4043 through the third bevel gear 4042, the driving rod 4044 drives the driving cam 4051 to rotate, the driving cam 4051 is attached to the lifting ring 4052, and as it rotates, the lifting ring 4052 slides up and down on the circular nozzle 4021. When the lifting ring 4052 slides upward, the connecting rope 4053 is pulled, and the flow guiding plate 4054 rotates around the hinge 4055 under the action of the connecting rope 4053, and the torsion resetting member 4056 is deformed by force. At this time, the angle of the flow guiding plate 4054 changes, and the spraying direction and range of the abrasive can be adjusted, so that the abrasive acts more precisely on a specific area of the stainless steel surface, meeting the requirements of complex shapes and fine processing. When the driving cam 4051 rotates in the reverse direction, the lifting ring 4052 descends, the torsion resetting member 4056 restores its deformation, and drives the flow guiding plate 4054 back to the initial position, facilitating the next adjustment. By designing the variable flow guiding structure 405, the present invention enables the circular nozzle 4021 to flexibly change the spraying path of the abrasive according to actual needs during the vertical spraying process, effectively improving the sandblasting effect and quality.

[0078] Through the angle adjustment structure 406, driven by the third motor 4041 as well, another set of drive rods 4044 drives the drive wheel 4061 to rotate. The drive wheel 4061 is in contact with the transmission ring 4062. When the drive wheel 4061 rotates, it drives the transmission ring 4062 to rotate. The transmission ring 4062 is installed outside the square nozzle 4031, thus realizing the adjustment of the angle of the square nozzle 4031. When performing vertical spraying on stainless steel, according to the shape, size of the workpiece and the different sandblasting parts, the spraying angle of the square nozzle 4031 can be flexibly changed, so that the abrasive can impact the stainless steel surface at the best angle, enhancing the sandblasting effect. Through the angle adjustment structure 406 of the present invention, whether sandblasting on a vertical surface, an inclined surface or a surface with a special angle, the angle adjustment structure 406 can ensure the accurate positioning of the square nozzle 4031, improving the pertinence and effectiveness of sandblasting.

[0079] Furthermore, as Figures 2 to 7 shown, the flat spraying assembly 5 of the present invention includes a flat spraying pipeline 501; the flat spraying pipeline 501 is installed in the sandblasting housing 301, and the sandblasting direction of the flat spraying pipeline 501 is perpendicular to the sandblasting directions of the circular nozzle 4021 and the square nozzle 4031. The flat spraying assembly 5 further includes a flat spraying flat opening 502; the flat spraying flat opening 502 is installed at the outlet end of the flat spraying pipeline 501, and the flat spraying pipeline 501 is a circumferential pipeline structure.

[0080] In the present invention, since the flat spraying pipeline 501 adopts a circumferential pipeline structure, when the abrasive flows in the circumferential pipeline, it will continuously collide and mix, so that the speed and density of the abrasive are more uniform. When the abrasive reaches the flat spraying flat opening 502, it can be sprayed out in a more stable and uniform state, ensuring that the sandblasting effect on the stainless steel plane is more consistent. The flat spraying flat opening 502 is installed at the outlet end of the flat spraying pipeline 501. The narrow and long cross-sectional shape of the flat opening compresses the abrasive jet into a flat fan shape, and the coverage area is larger than that of a circular nozzle. A wider plane area can be processed by a single spraying. Through the circumferential pipeline structure and the flat spraying flat opening 502 of the present invention, when polishing a high-brightness stainless steel plane, a uniform sandblasting texture is formed, increasing the sandblasting coverage area.
