Description

Technical Field

[0001] This utility model relates to a high-precision double-head sawing device for irregularly shaped aluminum profiles. Background Technology

[0002] Aluminum alloy profiles are metal structural materials made from aluminum with added alloying elements. They belong to the non-ferrous metal category and are mainly used in machinery manufacturing, transportation machinery, aerospace industry, and construction. The common length of aluminum alloy profiles delivered is 4 to 6 meters.

[0003] For production purposes, long aluminum alloy profiles are typically cut into shorter profiles of the required design length. Common lengths for these shorter profiles range from 70 to 120 mm. They can be used for doors and windows, display racks, large display racks, door and window frames, heavy-duty doors and windows, and supports.

[0004] During their work, the inventors discovered that profile cutting in factories typically uses hand-operated profile cutting machines. These machines include a base and a rotatable clamp, with the clamp mounted on the base. During cutting, the profile is secured using the clamp before cutting. This results in some profile segments having uneven end faces, reducing cutting quality and hindering the use of the segments. Therefore, to address the shortcomings of existing technology, a high-precision double-head sawing device for irregularly shaped aluminum profiles has been developed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-precision double-head sawing device for irregularly shaped aluminum profiles.

[0011] Furthermore, the driving moving component includes a base plate, on the top of which at least one reinforcing rib is mounted; a support base, which is mounted on the bottom of the base plate; a driving wheel, which is rotatably mounted on the support base; and a first driving motor, which has a first output shaft mounted on the bottom of the base plate, and the first output shaft is connected to the driving wheel in a transmission manner.

[0012] Furthermore, the high-precision double-head sawing device for irregular aluminum profiles of this utility model also includes a first slider, a support platform and a first guide rail.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments in this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0021] Example 1: like Figure 1-10As shown, a high-precision double-head sawing device for irregularly shaped aluminum profiles includes a first worktable 1, a second worktable 2, a telescopic extrusion member 15, a movable pressure member 14, a pad block 16, a first slider 7, a support platform 8, and a first guide rail 6. The second worktable 2 is arranged parallel and aligned with the first worktable 1 at intervals. The first worktable 1 and the second worktable 2 are provided with guide plates whose width direction is perpendicular to the table surface, and cutting devices 9 are slidably installed at the bottom. Each cutting device 9 is connected to a telescopic drive member 4. The cutting device 9 is provided with a saw blade 91. The two guide plates are aligned in a straight line, and the guide plates are provided with first cutting grooves 100 for the saw blade 91 to pass through. The first worktable 1 and the second worktable 2 are both provided with telescopic extrusion members 15 whose telescopic direction is perpendicular to the guide plates. The two telescopic extrusion members 15 are located between the two first cutting grooves 100. A telescopic support member 17 is installed on the second worktable 2 and is located on the side of the first cutting groove 100 away from the telescopic extrusion member 15. The direction of the horizontal telescopic support member 17 is parallel to the guide plate. Both the first workbench 1 and the second workbench 2 have a second cutting groove 200 communicating with the first cutting groove 100 on their surfaces. The second cutting groove 200 allows the saw blade 91 to move along the workbench surface. Both the first workbench 1 and the second workbench 2 are equipped with cantilever arms. Each cantilever arm is equipped with a liftable movable pressure member 14. A pad block 16 is placed on the workbench surface and located below the movable pressure member 14. The bottom of the movable pressure member 14 is equipped with a third cutting groove 300 corresponding to the second cutting groove 200. The bottom of both the first workbench 1 and the second workbench 2 are equipped with a first guide rail 6. A support platform 8 is slidably mounted on the first guide rail 6 via multiple first sliders 7 to support and install the cutting device 9 and is connected to the telescopic drive member 4 for transmission.

[0022] like Figure 1-4 As shown, to ensure stable movement of the support platform, two parallel first guide rails 6 are used. The two first guide rails 6 work together to support and slide the support platform. In this embodiment, each side of the support platform is slidably connected to the corresponding first guide rail 6 via two first sliders 7. The support platform can slide smoothly along the first guide rails with the help of the first sliders.

[0023] like Figure 1-4 As shown, the cantilever includes a first cantilever 11 and a second cantilever 21. A first base 12 is provided on the first worktable 1, and the first cantilever 11 is disposed on the first base 12. A second base 22 is provided on the second worktable 2, and the second cantilever 21 is disposed on the second base 22.

[0024] like Figure 1-4 As shown, the work surface includes a first work surface 13 and a second work surface 23. The first work surface 13 is placed on top of the first workbench 1. The second work surface 23 is placed on top of the second workbench 2.

[0025] like Figure 1-4As shown, the guide plate includes a first guide plate 14 and a second guide plate 24. The first guide plate 14 is perpendicularly arranged to the second cutting groove 200 on the first table 13 and is attached to the first base 12. The second guide plate 24 is perpendicularly arranged to the second cutting groove 200 on the second table 23 and is attached to the second base 22.

[0026] like Figure 1-4 As shown, the first cutting groove 100 on the first base 12 corresponding to the first guide plate 14 is provided with a saw blade moving groove. The first cutting groove 100 on the second base 22 corresponding to the second guide plate 24 is provided with a saw blade moving groove. It can be understood that the saw blade moving groove allows the saw blade to be moved and stored at the bottom of the first base and the second base.

[0027] The movable clamping member 14 can move up and down relative to the cantilever. When moving downwards, the movable clamping member 14 moves downwards to fit against the top surface of the profile to be cut, while its bottom surface also fits against the top surface of the pad. The movable clamping member, by its own weight, can press down on the profile to be cut, preventing the profile from moving upwards during cutting. When moving upwards, the movable clamping member moves upwards to a set position, where it is suspended on the cantilever. The movable clamping member disengages from the profile, making it easy to remove the cut profile.

[0028] like Figure 6 As shown, a structure of a movable pressure member is given. The movable pressure member 14 includes a pressure block 141 and a lifting drive member 143. The pressure block 141 has at least one guide rod 142 at its top and a third cutting groove 300 at its bottom. At least one guide rod 142 passes through the cantilever. The lifting drive member 143 has a lifting rod 1431. The lifting drive member 143 is installed on the top of the cantilever, and the lifting rod 1431 passes through the cantilever and connects to the pressure block 141.

[0029] The number of guide rods 142 can be 1, 2, 3, or 4. The preferred number of guide rods is 2, as 2 guide rods can better prevent the pressure block from swinging during up and down movement.

[0030] The lifting drive component can be a pneumatic cylinder or a hydraulic cylinder. Both pneumatic and hydraulic cylinders can drive the lifting rod to retract upwards and extend downwards.

[0031] When cutting profiles, the lifting drive 143 drives the lifting rod 1431 to extend downwards, simultaneously moving the pressure block 141 downwards. When the pressure block 141 moves to the top surface of the aluminum alloy profile 30 to be cut and the pad 16, the lifting drive 143 stops driving the lifting rod to extend downwards. The pressure block then presses the aluminum alloy profile 30 to be cut downwards by its own weight.

[0032] After the cutting is completed, the lifting drive 143 drives the lifting rod 1431 to retract upward, while simultaneously moving the pressure block 141 upward. When the lifting rod retracts upward to the set retraction stroke, the lifting drive stops driving the lifting rod to move, and the pressure block stops moving and hovers below the cantilever.

[0033] like Figure 5 As shown, one structure of the cutting device 9 includes a support 94, a cutting shaft 92, a cutting drive motor 95, and a transmission component 96. A bearing housing 93 is mounted on the top of the support 94. The cutting shaft 92 passes through the bearing housing 93, with a saw blade 91 mounted at one end and a driven wheel 98 mounted at the other end. The cutting drive motor 95 has an output shaft 951, on which a cutting drive wheel 97 is mounted. The cutting drive wheel 97 and the driven wheel 98 are connected by the transmission component 96.

[0034] The transmission component can be a transmission belt. The driving and driven pulleys of the cutter can be a belt pulley structure.

[0035] How the cutting device 9 works: The cutting drive motor 95 drives the output shaft 951 to rotate, the output shaft 951 drives the cutting drive wheel 97 to rotate, the cutting drive wheel 97 drives the driven wheel 98 to rotate through the transmission component 96, the driven wheel 98 drives the cutting shaft 92 to rotate, and the cutting shaft 92 drives the saw blade 91 to rotate.

[0036] It should be noted that when the saw blade is cutting the aluminum alloy profile, it moves from the first cutting groove into the second cutting groove while simultaneously cutting the profile. The movable pressure piece 14 has a third cutting groove corresponding to the second cutting groove. When cutting along the second cutting groove, the top of the saw blade enters the third cutting groove at the bottom of the movable pressure piece, preventing the saw blade from cutting the pressure block.

[0037] like Figure 1-4 As shown, brackets 5 are installed on both the first workbench 1 and the second workbench 2. The brackets 5 are used to support and install the telescopic drive component 4.

[0038] The telescopic drive component 4 is equipped with a first piston 41, which connects the telescopic drive component 4 to the support platform 8. When the telescopic drive component 4 drives the first piston 41 to retract, the first piston 41 drives the support platform 8 to move along the first guide rail 6 toward the telescopic drive component 4. When the telescopic drive component 4 drives the first piston to extend, the first piston 41 pushes the support platform 8 along the first guide rail 6 in a direction away from the telescopic drive component 4.

[0039] Understandably, when the support platform moves, the cutting device mounted on the support platform moves along with it, which makes it easier for the saw blade to cut the aluminum alloy profile.

[0040] like Figure 7As shown, one structure of a telescopic extrusion member is illustrated. The telescopic extrusion member 15 includes a first base plate 151, on which a first telescopic drive member 152 is mounted. The first telescopic drive member 152 is provided with a second piston 1521, which is connected to a pressure plate 153. Operation: The first telescopic drive member 152 drives the second piston 1521 to extend and retract, and the second piston 1521 drives the pressure plate 153 to move. When it is necessary to extrude the aluminum alloy profile to be cut, the first telescopic drive member 152 drives the second piston 1521 to extend towards the guide plate. The second piston 1521 pushes the pressure plate 153 to move and extrudes the aluminum alloy profile to be cut against the guide plate. At this time, the first telescopic drive member stops driving the first piston to extend, and the first piston remains supporting the pressure plate. The pressure plate and the guide plate clamp and fix the aluminum alloy profile to be cut. After cutting, the first telescopic drive 152 drives the first piston 1521 to retract, and the first piston 1521 drives the pressure plate to disengage from the aluminum alloy profile. The pressure plate and guide plate are released from clamping and fixing the aluminum alloy profile, and the cut aluminum alloy profile can be taken out from the first worktable and the second worktable.

[0041] like Figure 8 As shown, a structure of a telescopic support member is given. The telescopic support member 17 includes a second base plate 171, a second telescopic drive member 172 is mounted on the second base plate 171, and the second telescopic drive member 172 is provided with a third piston 1721, which is connected to the top plate 173.

[0042] The second telescopic drive 172 drives the third piston 1721 to telescopically move, and the third piston 1721 drives the top plate 173 to telescopically move. The third piston 1721 moves the top plate 173 to the edge of the second cutting groove 200, so that the surface of the top plate is aligned with the side of the second cutting groove. It can be understood that during operation, in order to ensure that the third piston pushes the top plate accurately to the edge of the groove, the stroke of the second telescopic drive driving the third piston to reciprocate can be preset, so that the third piston can push the top plate to the edge of the second cutting groove each time.

[0043] It should be noted that when cutting the aluminum alloy profile, the aluminum alloy profile 30 is pushed against the first guide plate 14 and enters the second worktable 2. It then moves against the second guide plate 24 until the end face of the aluminum alloy profile touches the top plate 173, at which point the pushing of the aluminum alloy profile 30 stops. The top plate can be used to position and block the aluminum alloy profile 30.

[0044] It should also be noted that when the aluminum alloy profile 30 to be cut is being cut, the third piston drives the top plate to retract and reset, which facilitates the saw blade to cut the end of the aluminum alloy profile 30 to be cut.

[0045] Both the first telescopic drive component 152 and the second telescopic drive component 172 can be pneumatic cylinders or hydraulic cylinders.

[0046] like Figure 2 As shown, to assist in pushing the aluminum alloy profile to be cut into the first worktable, a support frame 32 is added. Multiple rollers 31 are spaced apart and arranged in parallel on the top of the support frame 32. The two ends of each roller 31 are rotatably connected to the support frame 32 via a rotating shaft 311. The top cut surfaces of the multiple rollers are aligned with the first surface of the first worktable. During cutting, placing the aluminum alloy profile to be cut on the multiple rollers facilitates its movement towards the first worktable.

[0047] In some alternative embodiments, a structure for moving and clamping the second worktable is provided, such as... Figure 1 , 2 As shown in Figure 4, a second slider 25, a drive moving part 26, a clamping and locking part 27, a rack 28, and two parallel second guide rails 29 are added. The bottom of the second worktable 2 is slidably mounted on the second guide rails 29 via multiple second sliders 25. The rack 28 is arranged parallel to one of the second guide rails 29. The drive moving part 26 is mounted on the second worktable 2 and meshes with the rack 28 for transmission. The clamping and locking part 27 is mounted on the second worktable 2 and clamps and locks with one of the second guide rails 29.

[0048] The bottom ends of the second worktable 2 are each slidably connected to the corresponding second guide rail 29 by at least two second sliders 25. The second worktable 2 can slide along the second guide rail by means of the second sliders 25.

[0049] The clamping and locking member 27 is installed on the second worktable 2 and can be movably clamped and fixedly connected to the second guide rail. When the clamping and locking member 27 is released from the clamping and locking state with the second guide rail, the second worktable 2 can move along the second guide rail by means of the second slider 25 when a force is applied to the second worktable 2. When the clamping and locking member 27 is clamped and locked with the second guide rail, the second worktable 2 can move along the second guide rail by means of the second slider 25 when a force is applied to the second worktable 2.

[0050] The driving moving part 26 and the clamping locking part 27 are used as follows: When the clamping locking part 27 releases its clamping and fixing of the second guide rail, the driving moving part 26 engages with the rack 28 for transmission. With the help of the rack 28, the driving moving part 26 pushes the second worktable to move. When the second worktable moves closer to the first worktable, the distance between the first worktable and the second worktable is shortened; when the second worktable moves away from the first worktable, the distance between the first worktable and the second worktable is increased.

[0051] In some alternative embodiments, a structure for the clamping and locking element is provided, such as... Figure 10As shown, the clamping and locking component 27 includes a base 271, a telescopic clamping component 277, a movable clamp 272, a sleeve 275, and a second shaft 274. One end of the base 271 is provided with a swing groove 2711, and the other end is provided with a fixed clamp 276; the movable clamp 272 passes through the swing groove 2711 and is rotatably connected to the base 271 through the first shaft 273, and has a mounting groove 2721 at its top end; the telescopic clamping component 277 is provided with a fourth piston 2771; the sleeve 275 is placed in the mounting groove 2721; the second shaft 274 passes through the sleeve 275 and is rotatably connected to the movable clamp 272 at both ends.

[0052] like Figure 10 As shown, when the movable clamp 272 swings, the second shaft 274 can move within the sleeve 275.

[0053] The telescopic clamping component can be constructed using either a pneumatic or hydraulic cylinder. Pneumatic or hydraulic cylinders can smoothly drive the fourth piston to extend and retract.

[0054] How the clamping and locking components work: Clamping and locking operation: The telescopic clamping member 277 drives the fourth piston 2771 to extend. The fourth piston 2711 pushes the sleeve 275, the sleeve 275 pushes the second shaft 274, the second shaft 274 pushes the movable clamp 272. Under the support of the first shaft 273, the movable clamp 272 swings towards the fixed clamp 276 in the swing groove 2711 until the movable clamp 272 and the fixed clamp 276 clamp the second guide rail 29. Then the telescopic clamping member stops driving the fourth piston to extend and keeps the fourth piston supporting the sleeve 275. The sleeve 275 supports the second shaft 274. The movable clamp 272 remains stationary relative to the fixed clamp 276, thus realizing the clamping and locking operation.

[0055] Release of clamping operation: The telescopic clamping member 277 drives the fourth piston 2771 to retract. The fourth piston 2711 drives the sleeve 275 to move closer to the telescopic clamping member 277. The sleeve 275 drives the second shaft 274 to move. The second shaft 274 drives the movable clamp 272 to swing away from the fixed clamp 276. The movable clamp 272 and the fixed clamp 276 release the clamping state of the second guide rail, realizing the release of the clamping and locking state. The second worktable can slide along the second guide rail.

[0056] In some alternative embodiments, one structure for driving the moving part is provided. For example... Figure 9 As shown, the driving moving component 26 includes a base plate 262, a support base 264, a driving wheel 263, and a first driving motor 265. At least one reinforcing rib 261 is mounted on the top of the base plate 262; the support base 264 is mounted on the bottom of the base plate 262; the driving wheel 263 is rotatably mounted on the support base 264; the first driving motor 265 has a first output shaft, which is mounted on the bottom of the base plate 262, and the first output shaft is connected to the driving wheel 263 in a transmission manner.

[0057] The substrate 262 and the second worktable 2 can be connected by at least one reinforcing rib 261. The number of reinforcing ribs can be one, two, or three, etc. The reinforcing ribs can enhance the connection stability between the substrate and the second worktable.

[0058] How the moving parts work: When the clamping locking member 27 is released from the clamping and locking state, the first drive motor 265 drives the first output shaft to rotate. When the first output shaft drives the drive wheel 263 to rotate, under the support of the support base 264, the drive wheel 263 and the rack 28 are stably meshed and connected, thereby driving the base plate 262 to move. The base plate 262 then drives the second worktable to move stably along the second guide rail.

[0059] Understandably, the driving moving component can move the second worktable (in the unlocked state), which makes it easy to adjust the distance between the second worktable and the first worktable. This also allows for adjusting the distance between the second cutting groove on the first worktable and the second cutting groove on the second worktable, thereby cutting short profiles of different lengths.

[0060] In some optional embodiments, a positioning mechanism 10 and a controller 3 are added to facilitate limiting the reciprocating travel of the saw blade. For example... Figure 1-5 As shown, the positioning mechanism 10 includes a support rod 105, a first touch rod 104, a second touch rod 106, a first positioning sensor 103, a second positioning sensor 107, and a mounting plate 101. The first positioning sensor 103 and the second positioning sensor 107 are installed at intervals on the mounting plate 101. The support rod 105 is placed between the first positioning sensor 103 and the second positioning sensor 107 and is installed on the support platform 8. One end of the support rod 105 is provided with the first touch rod 104, and the other end is provided with the second touch rod 106. The first positioning sensor 103, the second positioning sensor 107, and the telescopic drive component 4 are all electrically connected to the controller 3.

[0061] When the mounting plate 101 is installed, the wide side of the mounting plate is set vertically, which can facilitate the support and installation of the first positioning sensor 103 and the second positioning sensor 107.

[0062] One installation method for the first positioning sensor 103, the second positioning sensor 107, and the mounting plate is a detachable installation. Specifically, the mounting plate 101 is provided with an adjustment groove 102, and the first positioning sensor 103 and the second positioning sensor 107 are respectively connected to the adjustment groove 102 by bolts 108. The adjustment groove 102 extends along the length of the mounting plate, which facilitates the adjustment of the distance between the first positioning sensor 103 and the second positioning sensor 107, thereby adjusting the reciprocating stroke of the saw blade.

[0063] During operation, the first positioning sensor 103 is matched with the first touch rod 104, and the second positioning sensor is matched with the second touch rod 106. That is, when the support platform 8 drives the first touch rod 104 to touch the first positioning sensor 103, the first positioning sensor 103 sends data information to the controller 3. When the controller receives the data information, it controls the telescopic drive component 4 and the cutting drive motor 95 to stop working.

[0064] When the cutting is started by the controller, the telescopic drive 4 pushes the support platform 8 to move through the first piston 41. The support platform 8 drives the cutting device 9 to move. The cutting drive motor 95 drives the saw blade 94 to rotate. The saw blade 94 moves from the first cutting groove 100 to cut into the second cutting groove 200. When the second touch rod 106 touches the second positioning sensor 107, the second positioning sensor 107 sends data information to the controller 3. When the controller 3 receives the data information, it controls the telescopic drive 4 to drive the first piston 41 in the reverse direction. The first piston retracts, causing the support platform 8 and the cutting device 9 to move in the reverse direction and reset. When the first touch rod 104 touches the first positioning sensor 103, the first positioning sensor 103 sends data information to the controller 3 again. When the controller receives the data information, it controls the telescopic drive 4 and the cutting drive motor 95 to stop working.

[0065] The working method of this utility model: The worker pushes the aluminum alloy profile to be cut onto the first guide plate 14 on the first workbench 1 towards the second workbench 2. When it enters the second workbench, the aluminum alloy profile to be cut moves onto the second guide plate 24 until it touches the top plate 173 of the telescopic support member 17. Then, the telescopic pressing member 15 on the first workbench 1 and the second workbench 2 presses and fixes the aluminum alloy profile to be cut onto the guide plate. Then, the movable pressing member 14 lowers the pressing block 141 to touch the top surface of the aluminum alloy profile. The pressing block 141 presses the aluminum alloy profile 30 to be cut, and the telescopic support member 17 is controlled to retract, causing the top plate 173 to detach from the aluminum alloy profile 30 to be cut.

[0066] Then, the controller controls the telescopic drive component 4 and the cutting drive motor 95 on the cutting device 9 to start. The telescopic drive component 4 pushes the support table 8 to move along the first guide rail 6 toward the aluminum alloy profile to be cut. When the saw blade 91 moves to the point where the first cutting groove 100 and the second cutting groove 200 are connected, the saw blade 91 cuts the aluminum alloy profile. As the saw blade moves, it cuts until the aluminum alloy profile is cut off. During the cutting process, the operator can support the aluminum alloy profile located on the first workbench 1 (the support point is away from the first cutting groove and the second cutting groove). The aluminum alloy profile segment overlapping between the first workbench and the second workbench is fixed by two telescopic extrusion components, and the top is squeezed by the pressure block 141 during cutting. Therefore, the aluminum alloy profile segment is effectively fixed, and the saw blades on the first workbench 1 and the second workbench 2 cut at the same time, which makes the cut end face flat.

[0067] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
