Description

Technical Field

[0001] This invention belongs to the field of aluminum alloy door and window processing technology, specifically relating to an aluminum alloy door and window frame processing device and its processing method. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, mullions, and sashes. Currently, aluminum alloy doors and windows include those made of aluminum alloy as the load-bearing member base material and composites of wood and plastic, also known as aluminum-wood composite doors and windows or aluminum-plastic composite doors and windows. Due to their beautiful appearance and good corrosion resistance, light weight, and durability, they occupy an important position in the building decoration market.

[0003] In the existing aluminum alloy door and window manufacturing process, the aluminum alloy window frame profiles are first quantitatively cut according to the required door and window dimensions. Then, the aluminum alloy profiles are assembled into doors and windows using connectors, seals, and opening and closing hardware. However, when operators operate the cutting equipment at close range to cut the aluminum alloy profiles, the cutting blades are exposed to the environment, causing metal shavings to fly everywhere, which can easily injure the operator's skin, resulting in a low safety factor. Furthermore, if the flying metal shavings are not cleaned up promptly, they can scratch the surface of the aluminum alloy profiles when they are pushed to the cutting position, affecting the appearance quality of the aluminum alloy profiles. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and reasonably designed aluminum alloy door and window frame processing device and processing method to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] An aluminum alloy door and window frame processing device is used to cut window frame profiles placed on a workbench. The processing device includes:

[0007] A cutting mechanism is provided on one side of the workbench where the profile is placed. The cutting mechanism includes a cutting blade, and a cutting clearance groove is provided on the workbench at the position corresponding to the cutting blade.

[0008] A protective cover is installed on the outside of the cutting mechanism;

[0009] The cleaning mechanism includes a first cleaning component and a second cleaning component. The first cleaning component is mounted on a protective cover and is used to sweep debris on the surface of the workbench inside the protective cover into the cutting clearance groove. The second cleaning component is mounted on the first cleaning component and is used to sweep away debris on the surface of the profile exposed inside the protective cover.

[0010] A collection mechanism for collecting debris generated during cutting.

[0011] As a further optimization of the present invention, two sets of the first cleaning components are provided. Along the extension direction of the profile, the two sets of the first cleaning components are respectively located on both sides of the cutting clearance groove. The first cleaning component includes a limiting plate, a guide plate, a first cleaning brush, a bracket, a first lead screw, and a first motor. Along the extension direction of the profile, the limiting plate is rotatably connected to the inner side wall of the protective cover, and the limiting plate is slidably connected to the guide plate. The guide plate has an inlet at one end near the worktable, which is used to make way for the profile placed on the worktable. The first cleaning brush is rotatably connected to the end of the guide plate away from the limiting plate. The first cleaning brush is threadedly connected to the first lead screw. One end of the first lead screw is rotatably connected to the bracket, and the bracket is fixedly connected to the protective cover. The input end of the first lead screw is fixedly connected to the first motor. The two first cleaning brushes move in opposite directions. When the protective cover is in the protective position, the first cleaning brushes are in frictional contact with the worktable surface.

[0012] As a further optimization of the present invention, the first cleaning assembly further includes a scraper and a spring. The scraper is obliquely disposed on the side of the first cleaning brush facing the cutting blade. The scraper is slidably connected to the first cleaning brush. A spring is fixedly connected to one end of the scraper inside the first cleaning brush. The end of the spring away from the scraper is fixedly connected to the first cleaning brush. The scraper has a bevel at one end outside the first cleaning brush. The edge of the cutting clearance groove has a rounded protrusion. The bevel and the rounded protrusion are correspondingly disposed.

[0013] When the first cleaning brush moves toward the cutting blade and the scraper is spaced apart from the worktable, the lowest point of the scraper is lower than the surface of the worktable.

[0014] As a further optimization of the present invention, the second cleaning assembly includes a cleaning displacement assembly, a second cleaning brush, and a steel coil. The second cleaning brush is located on the side of the feed inlet facing the cutting blade. The bristles of the second cleaning brush are in frictional engagement with the upper surface of the profile. The steel coil is fixedly connected to the side of the second cleaning brush facing the feed inlet. The other end of the steel coil extends into the guide plate through the feed inlet. When the first cleaning brush moves toward the cutting blade, the cleaning displacement assembly drives the second cleaning brush to move in the same direction. The moving speed of the first cleaning brush is less than the moving speed of the second cleaning brush.

[0015] As a further optimization of the present invention, the cleaning and shifting assembly includes a drive gear, a driven gear, a telescopic rod, and a guide rail. The drive gear is fixedly installed on one end of the guide plate near the first cleaning brush, and the drive gear meshes with the driven gear for transmission.

The second cleaning brush is slidably connected to the guide rail, and the guide rail is fixedly installed on the first cleaning brush.

[0016] As a further optimization of the present invention, the second cleaning assembly further includes a stop bar and a third cleaning brush. Two third cleaning brushes are fixedly connected to the side of the second cleaning brush facing the worktable. One end of the third cleaning brush is rotatably connected to the second cleaning brush, and a torsion spring is sleeved at the rotatable connection between the third cleaning brush and the second cleaning brush. The third cleaning brush extends along a direction perpendicular to the worktable surface. The two third cleaning brushes are respectively located on the side surface of the profile. The bristle ends of the third cleaning brushes are in frictional contact with the side surface of the profile. A stop bar is fixedly connected to the side end of the third cleaning brush. The end of the stop bar away from the third cleaning brush is located between the telescopic rod and the guide plate, and the stop bar and the telescopic rod are in frictional contact.

[0017] As a further optimization of the present invention, the collection mechanism includes an air pump, a collection box, a first connecting pipe, and a second connecting pipe. The air pump's suction end is connected to the collection box, one end of the first connecting pipe is connected to the collection box, and the other end of the first connecting pipe is connected to the receiving box. One end of the second connecting pipe is connected to the collection box, and the other end of the second connecting pipe is connected to the protective cover. The receiving box is located below the workbench and is slidably connected to the workbench. When the cutting blade is in the cutting position, the receiving end of the receiving box is connected to the cutting clearance groove.

[0018] As a further optimization of the present invention, a clamping mechanism is installed on the workbench. The clamping mechanism is used to clamp and fix the profile to be cut, wherein the base of the clamping mechanism is slidably connected to the workbench.

[0019] The cleaning mechanism also includes a third cleaning component, which is disposed below the cutting clearance groove. The third cleaning component includes a fourth cleaning brush and a receiving seat. The fourth cleaning brush is located inside the receiving seat and is used to clean away debris from the cutting end face of the profile through the cutting clearance groove.

[0020] As a further optimization of the present invention, the cutting mechanism further includes a second motor, a second lead screw, a slider, and a third motor. The second motor is mounted on the protective cover, and the output end of the second motor is fixedly connected to the second lead screw. The slider is threadedly connected to the second lead screw, and the slider is slidably connected to the protective cover. The third motor is mounted on the side end of the slider, and the output shaft end of the third motor is fixedly connected to the cutting blade.

[0021] The present invention also provides a method for processing aluminum alloy door and window frames, applied to the above-mentioned aluminum alloy door and window frame processing device, the processing method comprising the following steps:

[0022] Step 1: Move the cutting mechanism until the cutting blade is in the cutting position, and use the cutting blade to cut the window frame profile fixed on the workbench. At this time, the lower end of the protective cover is in contact with the surface of the workbench.

[0023] Step 2: During the cutting process, the first cleaning component sweeps the debris on the workbench surface covered by the protective cover into the cutting clearance groove, and the second cleaning component sweeps away the debris on the side surface of the profile away from the cutting surface.

[0024] Step 3: After cutting, the distance between the cut surfaces of the two profiles is increased by moving the profile, and the debris on the side surface of the profile near the cut surface is swept away by the second cleaning component.

[0025] Step 4: Collect the debris generated during cutting using a collection mechanism.

[0026] The present invention has at least the following beneficial effects: The device of the present invention is equipped with a cutting mechanism, a protective cover, a cleaning mechanism, and a collection mechanism. During the cutting process, the first cleaning brush in the cleaning mechanism cleans the debris on the workbench surface, the second cleaning brush cleans the debris on the upper surface of the profile, and the third cleaning brush cleans the debris on the side surface of the profile, thereby cleaning the surface of the profile and preventing the debris from scratching the surface of the profile during stacking and transportation. At the same time, the protective cover protects the cutting process and prevents flying debris from splashing out, ensuring the personal safety of the operator. And with the help of the collection mechanism, the cleaned debris is collected in a unified manner, ensuring the cleanliness of the environment. Attached Figure Description

[0037] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0038] In existing technology, when aluminum alloy window frame profiles are cut, metal shavings mainly fly along the tangential direction of the cutting blade. This not only easily injures workers, but also causes large particles of shavings to accumulate on the work surface, while small particles float and settle on the surface of the profiles with the airflow. If not cleaned in time, the surface of the profiles is easily scratched during subsequent stacking and transportation, and the shavings are also easily caused to float again during handling, affecting the health of the handlers.

[0039] Please see Figures 1 to 9 The present invention provides an aluminum alloy door and window frame processing device for cutting window frame profiles placed on a workbench 4. The processing device includes:

[0040] A cutting mechanism 1 is provided on the side of the workbench 4 where the profile is placed. The cutting mechanism 1 includes a cutting blade 15. A cutting clearance groove 16 is provided on the workbench 4 at the position corresponding to the cutting blade 15.

[0041] Protective cover 2 is installed on the outside of the cutting mechanism 1;

[0042] The cleaning mechanism 3 includes a first cleaning component 31 and a second cleaning component 32. The first cleaning component 31 is installed on the protective cover 2 and is used to sweep debris on the surface of the workbench 4 located inside the protective cover 2 into the cutting clearance groove 16. The second cleaning component 32 is installed on the first cleaning component 31 and is used to sweep away debris on the surface of the profile exposed inside the protective cover 2.

[0043] Collection mechanism 6 is used to collect the debris generated during cutting.

[0044] For example, such as Figure 4 As shown, the cutting mechanism 1 also includes a second motor 11, a second lead screw 12, a slider 13, and a third motor 14. The second motor 11 is mounted on the protective cover 2. The output end of the second motor 11 is fixedly connected to the second lead screw 12. The slider 13 is threadedly connected to the second lead screw 12. The slider 13 is slidably connected to the protective cover 2. The third motor 14 is mounted on the side end of the slider 13. The output shaft end of the third motor 14 is fixedly connected to the cutting blade 15. A hydraulic drive component is fixedly installed on the outside of the protective cover 2. Under the drive of the hydraulic drive component, the protective cover 2 drives the cutting mechanism 1 to move down, so that the cutting blade 15 moves down to the cutting position. At this time, the lower edge of the cutting blade 15 is located in the cutting clearance groove 16, and the lower end face of the protective cover 2 is in contact with the table surface of the worktable 4. Under the drive of the third motor 14 and the second motor 11, the cutting blade 15 moves and rotates while cutting. The generated debris is covered by the protective cover 2 to prevent debris from splashing to the outside of the protective cover 2, thereby achieving safety protection for the workers and ensuring the cleanliness of the processing environment.

[0045] In one embodiment, please continue reading Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The first cleaning component 31 is provided in two sets, along the extension direction of the profile, such as... Figure 2As shown, the structure indicated by the dotted line represents the placement position of the profile, with the extension direction of the profile from left to right. Two sets of first cleaning components 31 are located on either side of the cutting clearance groove 16. Each first cleaning component 31 includes a limiting plate 315, a guide plate 316, a first cleaning brush 314, a bracket 311, a first lead screw 313, and a first motor 312. Along the extension direction of the profile, the limiting plate 315 is rotatably connected to the inner wall of the protective cover 2. The limiting plate 315 is slidably connected to the guide plate 316. The guide plate 316 has an inlet 317 at one end near the workbench 4. The feed inlet 317 is used to make way for the profile placed on the workbench 4. The end of the guide plate 316 away from the limiting plate 315 is rotatably connected to the first cleaning brush 314. The first cleaning brush 314 is threadedly connected to the first lead screw 313. One end of the first lead screw 313 is rotatably connected to the bracket 311. The bracket 311 is fixedly connected to the protective cover 2. The input end of the first lead screw 313 is fixedly connected to the first motor 312. The two first cleaning brushes 314 move in opposite directions. When the protective cover 2 is in the protective position, the first cleaning brushes 314 are in frictional contact with the surface of the workbench 4.

[0046] In the above embodiment, when the protective cover 2 moves down to the cutting blade 15 in the cutting protection position, the profile is located in the feed inlet 317. By providing first cleaning components 31 on both sides of the cutting clearance groove 16, the first motor 312 drives the first lead screw 313, causing the first cleaning brush 314 to move in the opposite direction. When the first cleaning brush 314 moves towards the cutting blade 15, the first cleaning brush 314 comes into frictional contact with the surface of the workbench 4, so as to sweep the debris on the surface of the workbench 4 into the cutting clearance groove 16. Moreover, during the cutting process, the first motor 312 reciprocates, so that the first cleaning brush 314 repeatedly cleans the surface of the workbench 4, improving the cleaning efficiency and ensuring the efficient collection of large particles of debris. At the same time, the guide plate 316 extends out of the limiting plate 315, and the two ends of the guide plate 316 and the limiting plate 315 are respectively attached to the inner wall of the protective cover 2 to effectively prevent debris from splashing out.

[0047] In one embodiment, see further. Figure 6 The first cleaning assembly 31 also includes a scraper 318 and a spring 319. The scraper 318 is obliquely disposed on the side of the first cleaning brush 314 facing the cutter 15. The scraper 318 is slidably connected to the first cleaning brush 314. The end of the scraper 318 located inside the first cleaning brush 314 is fixedly connected to the spring 319. The end of the spring 319 away from the scraper 318 is fixedly connected to the first cleaning brush 314. The end of the scraper 318 located outside the first cleaning brush 314 has a bevel. The edge of the cutting clearance groove 16 has an arc protrusion. The bevel and the arc protrusion are correspondingly disposed.

[0048] When the first cleaning brush 314 moves toward the cutting blade 15 and the scraper 318 is spaced apart from the worktable 4, the lowest position of the scraper 318 is lower than the surface of the worktable 4.

[0049] In the above embodiment, when the first cleaning brush 314 moves toward the direction close to the cutting blade 15, that is... Figure 6 When the first cleaning brush 314 moves to the left, the scraper 318 abuts against the surface of the workbench 4, pushing large particles of debris from the surface of the workbench 4 into the cutting clearance groove 16. Then, the first cleaning brush 314 is used to further clean the surface of the workbench 4, achieving efficient cleaning of debris from the surface of the workbench 4. Furthermore, when the first cleaning brush 314 moves to the left, its bristles bend to the right. When the first cleaning brush 314 moves to the position above the cutting relief groove 16, the bristles are no longer squeezed by the worktable 4. The bent bristles return to their original position, easily throwing the debris adhering to the bristles at an angle to the lower left onto the surface of the cutting blade 15, causing secondary splashing of debris. Therefore, in this embodiment of the invention, when the scraper 318 moves to the position above the cutting relief groove 16, the elastic force of the spring 319 makes the lowest position of the scraper 318 lower than the table surface of the worktable 4, so as to block the debris thrown out by the bent bristles and make the debris fall into the cutting relief groove 16, thus avoiding secondary splashing of debris.

[0050] In one embodiment, see further. Figure 2 , Figure 5 and Figure 7 The second cleaning assembly 32 includes a cleaning displacement assembly, a second cleaning brush 324, and a steel coil 323. The second cleaning brush 324 is located on the side of the feed inlet 317 facing the cutting blade 15. The bristles of the second cleaning brush 324 are in frictional engagement with the upper surface of the profile. The steel coil 323 is fixedly connected to the side of the second cleaning brush 324 facing the feed inlet 317. The other end of the steel coil 323 extends into the guide plate 316 through the feed inlet 317. When the first cleaning brush 314 moves toward the cutting blade 15, the cleaning displacement assembly drives the second cleaning brush 324 to move in the same direction. The moving speed of the first cleaning brush 314 is less than the moving speed of the second cleaning brush 324.

[0051] For example, the cleaning and shifting assembly includes a drive gear 322, a driven gear 321, a telescopic rod 326, and a guide rail 325. The drive gear 322 is fixedly installed on one end of the guide plate 316 near the first cleaning brush 314. The drive gear 322 meshes with the driven gear 321 for transmission. The telescopic rod 326 is fixedly connected to the side end of the driven gear 321. The other end of the telescopic rod 326 is rotatably connected to the second cleaning brush 324. The second cleaning brush 324 is slidably connected to the guide rail 325. The guide rail 325 is fixedly installed on the first cleaning brush 314.

[0052] In the above embodiment, when the first cleaning brush 314 moves toward the cutting blade 15, the tilt angle of the guide plate 316 increases. Through the meshing of the driving gear 322 and the driven gear 321, the telescopic rod 326 swings away from the guide plate 316, thereby causing the second cleaning brush 324 to move toward the cutting blade 15. This cleans debris from the upper surface of the profile away from the cutting surface. When the cutting blade 15 moves from one side of the profile to the other, i.e., after cutting is completed, the... Figure 2 In the indicated orientation, the profile located to the right of the cutting blade 15 is moved a certain distance to the right, increasing the distance between the cutting surfaces of the left and right profiles. Then, the moving distance of the second cleaning brush 324 is increased, so that the second cleaning brush 324 cleans the debris on the upper surface of the profile near the cutting surface, improving the cleaning effect of the profile surface. Furthermore, during the cleaning process of the second cleaning brush 324, the steel coil 323 is used to block the debris from falling back onto the cleaned profile surface. The steel coil 323 is flexible and is wound into the guide plate 316 by means of the winding assembly.

[0053] In one embodiment, see further. Figure 2 , Figure 5 and Figure 7 The second cleaning assembly 32 also includes a stop bar 327 and a third cleaning brush 328. Two third cleaning brushes 328 are fixedly connected to the side of the second cleaning brush 324 facing the worktable 4. One end of the third cleaning brush 328 is rotatably connected to the second cleaning brush 324, and a torsion spring is sleeved at the rotatable connection between the third cleaning brush 328 and the second cleaning brush 324. The third cleaning brush 328 extends along the direction perpendicular to the table surface of the worktable 4. The two third cleaning brushes 328 are respectively located on the side surface of the profile. The bristle ends of the third cleaning brush 328 are in frictional contact with the side surface of the profile. A stop bar 327 is fixedly connected to the side end of the third cleaning brush 328. The end of the stop bar 327 away from the third cleaning brush 328 is located between the telescopic rod 326 and the guide plate 316, and the stop bar 327 and the telescopic rod 326 are in frictional contact.

[0054] In the above embodiments, such as Figure 5 As shown, during the leftward movement of the second cleaning brush 324, the third cleaning brush 328 gradually moves relative to the left side of the telescopic rod 326. Constrained by the stop rod 327 and the telescopic rod 326, the third cleaning brush 328 rotates. Under the action of the bristles bending and returning to their original position, debris from the front and rear surfaces of the profile is swept and thrown onto the worktable 4. The combined cleaning by the scraper 318 and the first cleaning brush 314 improves the cleaning quality and prevents debris swept away by the third cleaning brush 328 from concentrating on the lower edge of the profile side, which would hinder the cleaning by the third cleaning brush 328. During the rightward movement of the third cleaning brush 328, the stop rod 327 and the telescopic rod 326 remain in constant frictional contact under the returning action of the torsion spring.

[0055] In one embodiment, please continue reading Figure 1 , Figure 2 , Figure 8 and Figure 9 The collection mechanism 6 includes an air pump 61, a collection box 62, a first connecting pipe 64, and a second connecting pipe 63. The air pump 61 is connected to the collection box 62. One end of the first connecting pipe 64 is connected to the collection box 62, and the other end of the first connecting pipe 64 is connected to the receiving box 65. One end of the second connecting pipe 63 is connected to the collection box 62, and the other end of the second connecting pipe 63 is connected to the protective cover 2. The receiving box 65 is located below the workbench 4 and is slidably connected to the workbench 4. When the cutting blade 15 is in the cutting position, the feeding end of the receiving box 65 is connected to the cutting clearance groove 16 to achieve unified collection of debris.

[0056] In one embodiment, such as Figure 1 A clamping mechanism 7 is installed on the workbench 4. The clamping mechanism 7 is used to clamp and fix the profile to be cut. The base of the clamping mechanism 7 is slidably connected to the workbench 4.

[0057] Continue reading Figure 1 , Figure 2 and Figure 9 The cleaning mechanism 3 also includes a third cleaning component 5, which is located below the cutting clearance groove 16. The third cleaning component 5 includes a fourth cleaning brush 51 and a receiving seat 52. The fourth cleaning brush 51 is located inside the receiving seat 52 and is used to clean the debris from the cutting end face of the profile through the cutting clearance groove 16.

[0058] In the above embodiment, a driving component is driven to the base of the clamping mechanism 7, a driving component is driven to one side of the receiving box 65, and a driving component is driven to the receiving seat 52. After cutting, driven by their respective driving components, the clamping mechanism 7 clamps the right-side profile and moves to the right to increase the distance between the cutting surfaces of the left and right profiles. After cleaning the side surface of the profile, the protective cover 2 is moved upward to move the cutting mechanism to the initial position. At the same time, the receiving box 65 moves to the left. The lower end of the cutting clearance groove 16 is exposed. At this time, the receiving seat 52 moves up until the fourth cleaning brush 51 is in the cleaning position. The input end of the fourth cleaning brush 51 is connected to a driving component. The driving component of the fourth cleaning brush 51 is a motor, which realizes the rotation of the fourth cleaning brush 51. The brush of the fourth cleaning brush 51 is soft. Under the drive of the motor, the fourth cleaning brush 51 passes through the cutting clearance groove 16 and rubs against the cutting surface of the profile to remove debris from the cutting surface and improve the surface cleaning effect of the profile.

[0059] It should be noted that the driving component is a hydraulic telescopic cylinder, which can be selected according to the telescopic stroke.

[0060] In one embodiment, the present invention also provides a method for processing aluminum alloy door and window frames, applied to the above-mentioned aluminum alloy door and window frame processing device, the processing method comprising the following steps:

[0061] Step 1: Move the cutting mechanism 1 to the cutting blade 15 to the cutting position, and use the cutting blade 15 to cut the window frame profile to be cut fixed on the workbench 4. At this time, the lower end face of the protective cover 2 is in contact with the table surface of the workbench 4.

[0062] Step 2: During the cutting process, the first cleaning component 31 sweeps the debris on the surface of the workbench 4 covered by the protective cover 2 into the cutting clearance groove 16, and the second cleaning component 32 sweeps away the debris on the side surface of the profile away from the cutting surface.

[0063] Step 3: After cutting, the distance between the cut surfaces of the two profiles is increased by moving the profile, and the debris on the side surface of the profile near the cut surface is swept away by the second cleaning component 32.

[0064] Step 4: Collect the debris generated during cutting using the collection mechanism 6.

[0065] It should be noted that, in use, the aluminum alloy door and window frame processing device uses the clamping mechanism 7 to fix the profile onto the workbench 4, and lowers the protective cover 2 to position the cutting blade 15 at the cutting position. During the cutting process, the first motor 312 drives the first cleaning brush 314 to move the scraper 318 towards the cutting blade 15, thereby cleaning the debris on the workbench 4. The scraper 318 prevents debris from being flung out by the bristles of the first cleaning brush 314. The material returns to the surface of the cutting blade 15. Simultaneously, the second cleaning brush 324 cleans the portion of the profile surface away from the cutting surface, and the third cleaning brush 328 cleans the debris on the front and rear side surfaces of the profile. After cutting, the right side of the profile is moved to increase the distance between the cutting surfaces of the two profile sections. At this time, the second cleaning brush 324 and the third cleaning brush 328 continue cleaning to thoroughly clean the surface of the profile. The debris is collected uniformly by the collection mechanism 6.
