Description

Technical Field

[0001] This invention relates to the field of aluminum panel processing technology, and in particular to a method for fluid precision grinding of the cut edges of perforated aluminum panels. Background Technology

[0002] Perforated aluminum panels are made of aluminum panels, which are architectural decorative materials that have undergone chromating and other treatments, followed by fluorocarbon spraying technology. Perforated aluminum panels need to be polished after cutting.

[0003] Chinese patent CN213054005U discloses a processing and polishing device for hollowed-out carved aluminum single panels, including a device support, a motor, a polishing disc, a first crank handle, and a second crank handle. The device support is equipped with a motor on the top, and a polishing disc is provided on the upper surface of the motor shaft. A first crank handle is provided on the left side of the first screw, and a second crank handle is provided on the right side of the second screw. A first adjusting screw is provided inside a circular groove seven, and a second adjusting screw is provided inside a circular groove eight. An adjusting base is fixed to the top of the first adjusting screw and the second adjusting screw.

[0004] While this patent addresses some of the problems in the background technology, the grinding device in this patent grinds the surface of the perforated aluminum panel. This results in a large number of burrs appearing on the cut edges of the perforated aluminum panel. Furthermore, because the perforated aluminum panel has perforated carvings, the cut edges of the perforated aluminum panel are discontinuous. Smaller carved areas are prone to deformation and breakage during the grinding process, making grinding quite difficult. Summary of the Invention

[0005] The purpose of this invention is to provide a fluid precision grinding method for the cut edges of perforated aluminum panels. The method employs three grinding processes: coarse grinding, medium grinding, and fine grinding, to complete the grinding of the cut edges of the perforated aluminum panels. Different methods are used in different processes to precisely remove burrs, achieving a polishing effect with high grinding precision, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for fluid precision grinding of the cut edges of a perforated aluminum panel, comprising the following steps:

[0007] S1 Fixture Installation: Inspect the cut hollowed-out aluminum panel, flatten the cut hollowed-out aluminum panel, and install the fixture.

[0008] S2 Fixture: Install the fixture with the hollowed-out carved aluminum panel into the abrasive box. After installation, the hollowed-out carved aluminum panel is set vertically, and the cut edge of the hollowed-out carved aluminum panel is at the bottom of the hollowed-out carved aluminum panel.

[0009] S3 Coarse Grinding: Coarse abrasive is sprayed into the abrasive box. The coarse abrasive contacts the edge of the hollowed-out carved aluminum panel. At the same time, the clamp is controlled to shake the hollowed-out carved aluminum panel. The coarse abrasive is sprayed from one side of the hollowed-out carved aluminum panel towards the edge of the panel. The spraying angle of the coarse abrasive is 45° and the spraying time is 20-30 seconds.

[0010] S4 Medium Grinding: Stop spraying coarse abrasive into the abrasive box, and then stop the hollow-carved aluminum panel by shaking it for 10 seconds using the clamp. Then spray medium abrasive into the abrasive box at an angle of 75° for 30-50 seconds.

[0011] S5 Fine Grinding: Stop spraying medium grinding abrasive into the abrasive box, and then stop the hollowed-out carved aluminum panel by shaking it for 10 seconds using the clamp. Then spray fine grinding abrasive into the abrasive box at an angle of 80° for 10-20 seconds.

[0012] S6 Cleaning: Compressed air is used to blow the perforated aluminum panel once to clean the abrasive residue on the surface of the perforated aluminum panel. Then, high-pressure pure water is used to clean the surface of the perforated aluminum panel. Compressed air is used for a second blow to dry most of the moisture. After drying, the panel is dried.

[0013] Preferably, the coarse grinding abrasive, the medium grinding abrasive, and the fine grinding abrasive all include water and abrasive particles, and the volume mixing ratio of abrasive particles to water is in the range of 10-30%.

[0014] Preferably, the particle size of the coarse grinding abrasive is 50-80 mesh, and the injection pressure of the coarse grinding abrasive is 20-50 MPa.

[0015] Preferably, the particle size of the medium grinding abrasive is 80-100 mesh, and the injection pressure of the medium grinding abrasive is 10-40 MPa.

[0016] Preferably, the particle size of the fine grinding abrasive particles is 120-150 mesh, and the injection pressure of the fine grinding abrasive is 10-30 MPa.

[0017] Preferably, the fixture includes a mounting plate, a locking post, and a sub-clamp. Two mounting plates are provided, and the two mounting plates are connected by the locking post. A clamping part is provided on one side of the mounting plate, and a sliding groove is provided at equal intervals on the clamping part. The sub-clamp is movably connected in the sliding groove.

[0018] Preferably, the clamping fixture includes a connecting column, a clamping head, and a threaded locking rod. One end of the connecting column is fixedly connected to the clamping head, and the other end of the connecting column is provided with a hollow column that engages with the threaded locking rod. The lower end of the threaded locking rod abuts against a sliding groove. A limiting plate is provided on the outer wall of the hollow column, and the limiting plate engages with the sliding groove. An inclined surface is provided on the clamping head.

[0019] Preferably, the lower surfaces of both the clamping part and the clamping head are provided with a wear-resistant and anti-slip silicone layer.

[0020] Preferably, the requirements for the mounting fixture in the S1 mounting fixture are as follows:

[0021] Expose the burrs along the edges of the perforated aluminum panel, and maintain a distance of 3-5mm between the edge of the clamp and the burrs.

[0022] For the small-area perforated aluminum panel, use a separate clamp for reinforcement and clamping, shortening the distance from the edge of the clamp to the burr. The shortened distance is based on the connection position between the base of the perforated part and the aluminum panel, and extends appropriately to the end of the perforated part, but does not cover the burr position. The end of the separate clamp can abut against the base of the burr.

[0023] Preferably, the specific method for the clamping fixture to hold the carved edge portion of the hollowed-out aluminum panel is as follows:

[0024] After the perforated aluminum panel above the edge is clamped and fixed by the clamping part, the perforated aluminum panel and the clamping fixture are fixed in position.

[0025] Manually loosen the threaded locking rod and push the hollow column towards the clamping head. The clamping head moves along the surface of the carved part of the hollowed-out aluminum panel.

[0026] The end of the clamping head away from the hollow column lifts the burr and pushes it toward the end of the edge of the hollowed-out aluminum panel until the end of the clamping head abuts against the root of the burr.

[0027] Tighten the loosening thread locking rod to fix the position of the connecting post;

[0028] Adjust the clamps on the other clamping part that correspond to the carved part of the above-mentioned hollowed-out aluminum panel until the clamping heads on both sides of the carved part of the hollowed-out aluminum panel clamp it together.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. The process involves three grinding steps: coarse grinding, medium grinding, and fine grinding. This process completes the grinding of the cut edges of the hollowed-out carved aluminum panel. Different methods are used in different steps to precisely remove burrs and achieve a polishing effect with high grinding precision.

[0031] 2. An inclined spray angle is used in rough grinding, medium grinding and fine grinding to prevent the abrasive from spreading upward from the hollow part of the hollowed-out aluminum panel, avoid contaminating the part of the hollowed-out aluminum panel that does not need to be ground, and reduce subsequent cleaning work.

[0032] 3. Use clamps to fix the hollowed-out carved aluminum panels, exposing the cut edges of the hollowed-out carved aluminum panels. The clamps can hold and fix the entire hollowed-out carved aluminum panels to prevent deformation during the grinding process.

[0033] 4. By setting up sub-clamps on the fixture to handle the small-area carvings on the edge of the hollow-carved aluminum panel, the clamping area of ​​the carvings on the hollow-carved aluminum panel can be increased. The carvings in different positions are reinforced and clamped to prevent bending and breakage of the small-area carvings, and to ensure the stability of the carvings during the fine grinding process.

[0040] 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.

[0041] Please see Figures 1-5 A method for fluid precision grinding of the cut edges of a perforated aluminum panel includes the following steps:

[0042] Step 1: Install the clamps, inspect the cut hollowed-out aluminum panels, flatten the cut hollowed-out aluminum panels, and install the clamps.

[0043] Step 2: Fix the clamp. Install the clamp with the hollowed-out carved aluminum panel into the abrasive box. The hollowed-out carved aluminum panel is set vertically after installation, and the cut edge of the hollowed-out carved aluminum panel is at the bottom of the hollowed-out carved aluminum panel.

[0044] Step 3: Coarse grinding. Coarse grinding abrasive is sprayed into the abrasive box. The coarse grinding abrasive contacts the edge of the hollowed-out carved aluminum panel. At the same time, the clamp is controlled to shake the hollowed-out carved aluminum panel to accelerate the removal of burrs. The coarse grinding abrasive is sprayed from one side of the hollowed-out carved aluminum panel towards the edge of the panel. The spraying angle of the coarse grinding abrasive is 45°, the spraying time is 20-30 seconds, the particle size of the coarse grinding abrasive is 50-80 mesh, and the spraying pressure of the coarse grinding abrasive is 20-50 MPa.

[0045] Specifically, the coarse abrasive has a higher spray pressure, which can remove the burrs attached to the edge of the hollowed-out aluminum panel at the fastest speed. The 45° angle of spraying can prevent the sprayed coarse abrasive from spreading to the part above the edge of the hollowed-out aluminum panel, reduce the wear of the coarse abrasive, and avoid contaminating the carved part of the hollowed-out aluminum panel.

[0046] Step 4: Medium grinding. Stop spraying coarse abrasive into the abrasive box. Use a clamp to shake the perforated aluminum panel for 10 seconds and then stop. By shaking, reduce the abrasive adhering to the perforated aluminum panel. Spray medium abrasive into the abrasive box. The spray angle of the medium abrasive is 75°, the spraying time is 30-50 seconds, the particle size of the medium abrasive is 80-100 mesh, and the spraying pressure of the medium abrasive is 10-40 MPa.

[0047] Specifically, after the coarse grinding removes large burrs, the finer-grained medium grinding abrasive is used for polishing, which can remove small burrs. At the same time, the medium grinding abrasive is set to be sprayed at a 75° angle to prevent the sprayed coarse grinding abrasive from spreading above the edge of the hollowed-out carved aluminum panel.

[0048] Step 5: Fine grinding. Stop spraying medium grinding abrasive into the abrasive box. Use a clamp to shake the hollowed-out carved aluminum panel for 10 seconds and then stop to accelerate the separation of the abrasive from the hollowed-out carved aluminum panel. Spray fine grinding abrasive into the abrasive box. The spray angle of the fine grinding abrasive is 80°, the spray duration is 10-20 seconds, the particle size of the fine grinding abrasive particles is 120-150 mesh, and the spray pressure of the fine grinding abrasive is 10-30 MPa.

[0049] Specifically, based on the medium grinding, further fine grinding is carried out to expand the grinding area and make the overall smoothness higher.

[0050] Step Six: Cleaning. Use compressed air to blow the perforated aluminum panel once to clean the abrasive residue on the surface of the perforated aluminum panel. Then, use high-pressure pure water to clean the surface of the perforated aluminum panel. Use compressed air to blow a second time to dry most of the moisture. Then, perform a drying process.

[0051] Coarse grinding abrasives, medium grinding abrasives, and fine grinding abrasives all contain water and abrasive particles, with the volume mixing ratio of abrasive particles to water ranging from 10% to 30%.

[0052] The fixture includes a mounting plate 1, a locking post 2, and a sub-clamp 3. There are two mounting plates 1, and the two mounting plates 1 are connected by the locking post 2. A clamping part 11 is provided on one side of the mounting plate 1. The long end of the clamping part 11 is not less than the length of the hollowed-out carved aluminum panel. The position of the hollowed-out carved aluminum panel is fixed by the clamping part 11. Slide grooves 111 are provided at equal intervals on the clamping part 11. The sub-clamp 3 is movably connected in the slide grooves 111.

[0053] Specifically, the mounting plate 1 has movable holes that match the locking pins 2, and the mounting plate 1 also has mounting holes for fixing the mounting plate 1 into the abrasive box. The two mounting plates 1 clamp and fix the hollowed-out aluminum single panel from both sides. The clamping part 11 is used to clamp the part above the cut edge of the hollowed-out aluminum single panel. The locking pins 2 are equipped with nuts. After the mounting plate 1 clamps the hollowed-out aluminum single panel, the nuts are tightened through the locking pins 2 that penetrate the mounting plate 1, so that the mounting plate 1 and the hollowed-out aluminum single panel cannot be separated.

[0054] The clamping fixture 3 includes a connecting column 31, a clamping head 32, and a threaded locking rod 33. One end of the connecting column 31 is fixedly connected to the clamping head 32, and the other end of the connecting column 31 is provided with a hollow column 311. The hollow column 311 engages with the threaded locking rod 33, and the lower end of the threaded locking rod 33 abuts against the slide groove 111. A limiting plate 312 is provided on the outer wall of the hollow column 311. The limiting plate 312 engages with the slide groove 111 and prevents the hollow column 311 from detaching from the top of the slide groove 111. An inclined surface is provided on the clamping head 32. The inclined surface is used for the downward movement of abrasive grains and plays a guiding role for the abrasive, preventing the abrasive from moving to the part above the edge of the hollow carved aluminum panel and avoiding contamination of the hollow carved aluminum panel.

[0055] The lower surfaces of both the clamping part 11 and the clamping head 32 are provided with a wear-resistant and anti-slip silicone layer.

[0056] Specifically, a wear-resistant and non-slip silicone layer is used to clamp the perforated aluminum panel, fixing its position and preventing scratches.

[0057] The requirements for installing the fixture in step one are as follows:

[0058] Expose the burrs along the edges of the perforated aluminum panel, and maintain a distance of 3-5mm between the edge of the clamp and the burrs.

[0059] For the small-area carved section of the perforated aluminum panel, use a clamp 3 for reinforcement and clamping, shortening the distance from the edge of the clamp to the burr. The shortened distance is based on the connection position between the root of the carved section and the perforated aluminum panel covered by the clamp 3, and extends appropriately to the end of the carved section, but does not cover the burr position. The end of the clamp 3 can abut against the root of the burr, which refers to the end position where the burr connects to the edge of the perforated aluminum panel.

[0060] The specific method for using the three clamps to hold the carved edge of the aluminum panel is as follows:

[0061] After the perforated aluminum panel above the edge is clamped and fixed by the clamping part 11, the perforated aluminum panel and the clamping fixture are fixed in position.

[0062] Manually loosen the threaded locking rod 33, push the hollow column 311 towards the clamping head 32, and the clamping head 32 moves along the surface of the carved part of the hollowed-out aluminum panel;

[0063] The end of the clamping head 32 away from the hollow column 311 lifts up the burrs and can also lift up some of the burrs, accelerating the subsequent cleaning of the burrs and preventing stubborn burrs from causing the carved part to bend. It pushes the burrs towards the edge of the hollow carved aluminum panel until the end of the clamping head 32 abuts against the root of the burr.

[0064] Tighten the loosening thread locking rod 33 to fix the position of the connecting post 31;

[0065] Adjust the sub-clamps 3 on the other clamping part 11 that correspond to the carved part of the above-mentioned hollowed-out aluminum panel until the clamping heads 32 on both sides of the carved part of the hollowed-out aluminum panel clamp it together.

[0066] Specifically, by adding a sub-clamp 3, the clamping area of ​​the carved part of the hollowed-out aluminum panel can be increased, and the carvings in different positions can be reinforced and clamped to prevent the small carved parts from bending and breaking, thereby ensuring that the hollowed-out aluminum panel does not deform during the fine grinding process.

[0067] In summary, the present invention proposes a fluid precision grinding method for the cut edges of perforated aluminum panels. This method employs three grinding processes: rough grinding, medium grinding, and fine grinding, to complete the grinding of the cut edges of the perforated aluminum panels. Different methods are used in each process to precisely remove burrs, achieving a polishing effect with high precision. An inclined spray angle is used in all three grinding stages to prevent abrasive from spreading upwards from the perforated parts of the aluminum panel, thus avoiding contamination of the unpolished areas and reducing subsequent cleaning work. The process involves using clamps to fix the perforated aluminum panels, exposing the cut edges. The clamps can hold and fix the entire perforated aluminum panel, preventing deformation during the grinding process. Three sub-clamps are set on the clamps to support the small areas of the perforated aluminum panels along their edges, increasing the clamping area for the perforated parts. This reinforces the clamping of the perforated parts in different locations, preventing bending and breakage of the smaller perforated areas and ensuring the stability of the perforations during the fine grinding process.

[0068] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
