Description

Technical Field

[0001] The 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 Art

[0002] Sandblasting is a treatment method used to improve the brightness and finish of stainless steel surfaces. Sandblasting uses compressed air to spray abrasives (such as aluminum oxide, silicon carbide, etc.) onto the surface of stainless steel at high speed. Through the impact and friction of the abrasive on the surface, impurities, oxide scale, tiny scratches, etc. on the surface are removed, and a uniform tiny concave-convex structure is formed on the surface, thereby achieving the effect of polishing and improving brightness. This tiny concave-convex structure can effectively scatter light, reduce diffuse reflection, and make the stainless steel surface present a high-brightness appearance.

[0003] However, the existing stainless steel sandblasting treatment mostly has a fixed spray direction, a single sandblasting mode, and a fixed nozzle type. It is difficult to quickly switch the sandblasting mode, which makes it difficult to meet the high-precision sandblasting and polishing requirements when it is necessary to take into account the vertical and flat surfaces, as well as the diversified high-brightness sandblasting needs of fine textures or large-area sandblasting. The sandblasting effect on the workpiece surface is uneven, especially when processing high-brightness stainless steel, which is prone to local over-blasting or missed blasting, affecting the surface finish and quality stability. In view of this, we propose a high-brightness stainless steel surface treatment equipment and treatment method. Summary of the invention

[0014] A high-brightness stainless steel surface treatment method includes the following steps: S1. Equipment startup and state switching: Place the stainless steel workpiece on the work station, check the sand material of the sandblasting machine body, start 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; S2. Sandblasting treatment: In the vertical spraying state, drive the first and second bevel gears and the mounting plate by the second motor to switch the circular or square spray pipe to be connected with the vertical spraying connecting pipe for vertical spraying preparation; When sandblasting with a round nozzle, drive the driving cam by the third motor, control the opening and closing of the flow guiding plate through the lifting ring and the connecting rope, adjust the sandblasting range and intensity, and cooperate with the circular spray pipe to form a columnar sandblasting surface and concentrate the spray onto the circular hole of the workpiece; When sandblasting with a square nozzle, drive the driving wheel by the third motor to drive the transmission ring, adjust the sandblasting angle of the square spray pipe, and cooperate with the square spray pipe to form a flat strip-shaped sandblasting surface and spray it onto the surface of the workpiece in a large range; In the flat spraying state, use the flat spraying pipeline and the flat nozzle, adjust their positions and angles, and use the surrounding pipeline to make the abrasive material spray out flat from the nozzle, forming a flat fan-shaped sandblasting surface to cover the surface of the workpiece. S3. Ending 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.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention can be flexibly switched between vertical spraying and flat spraying as needed through the adjustable conveying component, which has great advantages when processing high-brightness stainless steel. The vertical spraying precisely polishes the vertical surface, and the flat 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 circular 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 of various patterns. Through the multi-state and multi-mode adjustable sandblasting system of the present invention, the sandblasting machine can adapt to complex high-brightness stainless steel sandblasting and polishing tasks.

[0016] 2. The present invention adopts a rotary switching structure. Traditional sandblasting equipment relies on multiple valves to independently control the on-off of the pipeline. During operation, different valves need to be frequently opened and closed. However, the rotary disk of the present invention is precisely driven by the first motor, and through mechanical linkage, the connecting hose rotates synchronously, realizing one-key switching between the vertical spraying connecting pipe and the flat spraying connecting pipe. Compared with the traditional valve operation, the operation efficiency is improved. At the same time, the design of the tight fit between the rotary disk and the fixed disk uses surface sealing instead of 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. By setting a rotary switching structure instead of traditional valve control, the present invention improves the operation efficiency and reduces the risk of abrasive material leakage.

[0017] 3. The present invention adopts a variable flow guiding structure. When the third motor starts, the power is transmitted to the fourth bevel gear through the third bevel gear, and the driving rod drives the driving cam to rotate. 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 resetting member deforms under force. At this time, the angle of the flow guiding plate changes, which can adjust the spraying direction and range of the abrasive material, making the abrasive material act 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 reverse direction, the lifting ring descends, and the torsion resetting member restores its deformation, driving the flow guiding plate back to the initial position, facilitating the next adjustment. By designing a variable flow guiding structure, the present invention enables the circular nozzle to flexibly change the spraying path of the abrasive material according to actual needs during vertical spraying, effectively improving the sandblasting effect and quality.

[0018] 4. Through the angle adjustment structure of the present invention, under the drive of the third motor, another set of drive rods drives the driving wheel to rotate. The driving wheel is in contact with the transmission ring. When the driving wheel rotates, it drives the transmission ring to rotate. Since the transmission ring is installed outside the square nozzle, the angle of the square nozzle can be adjusted. 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.

[0019] 5. In the present invention, the flat spraying pipeline adopts a circumferential pipeline structure. When the abrasive flows in the circumferential pipeline, it will continuously collide and mix, making the speed and density of the abrasive 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. 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 with a single spray. 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.

[0035] Example 1: 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; The adjustable sandblasting system 2 has a vertical spraying state and a horizontal spraying state, and includes an adjustable conveying component 3, a vertical spraying component 4, and a horizontal spraying component 5; when the adjustable sandblasting system 2 is in the vertical spraying state, the adjustable conveying component 3 connects the vertical spraying component 4 with the sandblasting machine body 1 for vertical spraying work on the stainless steel; when the adjustable sandblasting system 2 is in the horizontal spraying state, the adjustable conveying component 3 connects the horizontal spraying component 5 with the sandblasting machine body 1 for horizontal spraying work on the stainless steel; The vertical spraying 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 spraying 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 the stainless steel; when the vertical spraying 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 the stainless steel.

[0036] 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 circular 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.

[0037] Specifically, as Figures 3 to 7As shown in the figure, 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 the fixed disk 305 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.

[0038] 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 accurately driven by the first motor 302. Through mechanical linkage, the connecting hose 304 rotates synchronously, 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. The present invention replaces the traditional valve control by setting the turntable 303 type switching structure, improving the operation efficiency and reducing the risk of sand material leakage.

[0039] It is worth noting that, as Figures 8 to 10 shown in the figure, the nozzle conversion structure 401 involved in the present invention includes a second motor 4011, a first bevel gear 4012, a second bevel gear 4013, and a mounting disk 4014. The second motor 4011 is installed inside 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. The mounting disk 4014 is installed inside the second bevel gear 4013.

[0040] The round nozzle sandblasting structure 402 includes a circular nozzle 4021, and the square nozzle sandblasting structure 403 includes a square nozzle 4031; the circular 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 circular nozzle 4021 is installed on both sides of the mounting plate 4014 along the diameter direction, and two square nozzles 4031 are rotatably connected in the other set of diameter directions perpendicular to the mounting plate 4014. The mounting plate 4014 is used to switch the two vertical spray connecting pipes 306 between the states of connecting the two circular nozzles 4021 and the two square nozzles 4031.

[0041] In the present invention, through the nozzle conversion structure 401, when the traditional sandblasting equipment switches different-shaped nozzles, manual disassembly and installation are required, 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 plate 4014 through the meshing second bevel gear 4013, so that the mounting plate 4014 rotates smoothly. During this process, the mounting plate 4014 drives the circular 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.

[0042] Furthermore, as Figures 10 to 14 shown, the vertical spray assembly 4 involved in the present invention further includes a driving structure 404. 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 plate 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 plate 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.

[0043] The vertical spraying assembly 4 further includes a variable flow guiding structure 405, and the variable flow guiding structure 405 includes a driving cam 4051, a lifting ring 4052, a connecting rope 4053, a flow guiding plate 4054, a hinge 4055, and a torsion reset member 4056; two driving cams 4051 are installed at the ends of a group 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 reset member 4056 is arranged between the flow guiding plate 4054 and the hinge 4055, and the torsion reset member 4056 is connected between the flow guiding plate 4054 and the hinge 4055.

[0044] The vertical spraying assembly 4 further includes an angle adjustment structure 406, and the angle adjustment structure 406 includes a driving wheel 4061 and a transmission ring 4062; two driving wheels 4061 are installed at the ends of another group 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 on the outside of the square nozzle 4031.

[0045] 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 reset member 4056 deforms under 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 reset 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 vertical spraying, effectively improving the sandblasting effect and quality.

[0046] Through the angle adjustment structure 406, also driven by the third motor 4041, 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, thereby 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 is performed on a vertical surface, an inclined surface or a surface with a special angle, the angle adjustment structure 406 can ensure the precise positioning of the square nozzle 4031, improving the pertinence and effectiveness of sandblasting.

[0047] 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 port 502; the flat spraying flat port 502 is installed at the outlet end of the flat spraying pipeline 501, and the flat spraying pipeline 501 is a circumferential pipeline structure.

[0048] By adopting a circumferential pipeline structure for the flat spraying pipeline 501 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 port 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 port 502 is installed at the outlet end of the flat spraying pipeline 501, and the narrow cross-sectional shape of the flat port compresses the abrasive beam into a flat fan shape, and the coverage area is larger than that of the circular nozzle. A wider plane area can be processed by a single spraying. Through the circumferential pipeline structure and the flat spraying flat port 502 of the present invention, when polishing a high-brightness stainless steel plane, a uniform sandblasting texture is formed, increasing the sandblasting coverage area.
