[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0032] Reference Figures 1 to 3 This utility model provides a sawing device for aluminum profile harmonica tubes, including a frame 100, a sawing structure, and a first transverse drive mechanism 220. The upper surface of the frame 100 has a processing position 110 for placing the aluminum profile harmonica tube workpiece to be sawed. The sawing structure includes a rotary drive mechanism 210 and a saw blade 200. The saw blade 200 is rotatably mounted below the frame 100 and partially protrudes upward from the upper surface of the frame 100. The rotary drive mechanism 210 is pultrusively connected to the saw blade 200 and can drive the saw blade 200 to rotate. The first transverse drive mechanism 220 is pultrusively connected to the saw blade 200 and can drive the saw blade 200 to move laterally through the processing position 110. The diameter of the saw blade 200 is D, and the height of the saw blade 200 protruding upward relative to the upper surface of the frame 100 is H, where 0.08 ≤ H / D ≤ 0.2.
[0033] By employing the aluminum profile harmonica tube sawing device of this embodiment, the height of the saw blade 200 extending out of the frame 100 is only 8%-20% of the diameter of the saw blade 200. This allows for sawing of the aluminum profile harmonica tube through the upper end of the saw blade 200, thereby reducing the contact area between the saw blade 200 and the cut surface of the aluminum profile harmonica tube during sawing. This reduces the pressure exerted by the saw blade 200 on the cut surface of the aluminum profile harmonica tube during sawing, lowering the risk of deformation and resulting in a smoother cut surface. Furthermore, compared to laser cutting, the aluminum profile harmonica tube sawing device of this invention uses mechanical sawing, resulting in lower equipment costs. The saw blade 200 can simultaneously saw 5-8 aluminum profile harmonica tubes, providing high processing efficiency.
[0034] It is understood that the rotary drive mechanism 210 can specifically adopt a motor or other rotary drive mechanism, and the first transverse drive mechanism 220 can specifically adopt a cylinder, linear push rod or other linear drive mechanism.
[0035] Reference Figures 1 to 3In some embodiments, the ratio of the height by which the saw blade 200 protrudes upward relative to the upper surface of the frame 100 to the diameter of the saw blade 200, H / D, is 0.15, thereby achieving a better sawing effect. Of course, this is only an exemplary description of a preferred embodiment of the present invention. In addition, H / D can also be set to 0.08, 0.13, 0.17, etc., and the present invention does not specifically limit this.
[0036] Reference Figures 1 to 3 In some embodiments, the frame 100 is provided with a first fixing mechanism 300, which includes a first pressing block 310, a downward pressing drive mechanism 320, and a second lateral driving mechanism 330. The second lateral driving mechanism 330 is mounted on the frame 100, the downward pressing drive mechanism 320 is movably mounted on the frame 100 and is driveably connected to the second lateral driving mechanism 330, and the first pressing block 310 is movably mounted above the processing position 110 and is driveably connected to the downward pressing drive mechanism 320; wherein, the second lateral driving mechanism 330 is capable of... The downward pressure drive mechanism 320 drives the first pressure block 310 to reciprocate relative to the frame 100 in the lateral direction. This allows the position of the first pressure block 310 in the lateral direction to be adjusted so that the first pressure block 310 can be aligned with the aluminum profile harmonica tube to be processed. The downward pressure drive mechanism 320 can drive the first pressure block 310 to move in the vertical direction closer to or away from the processing position 110. This allows the first pressure block 310 to press down and fix the aluminum profile harmonica tube to be processed, preventing it from shifting during the sawing process and affecting the sawing effect.
[0037] It is understandable that the first pressure block 310 can be made of rubber, silicone or other flexible materials, thereby avoiding damage to the aluminum harmonica tube caused by the first pressure block 310.
[0038] It is understandable that the downward drive mechanism 320 and the second lateral drive mechanism 330 can both specifically adopt linear drive mechanisms such as cylinders and linear push rods.
[0039] Reference Figures 1 to 3 In some embodiments, the frame 100 is provided with a clearance groove 120 for the saw blade 200 to move laterally. The clearance groove 120 is arranged in the lateral direction and passes through the processing position 110. There are two sets of first fixing mechanisms 300. The first pressure blocks 310 of the two sets of first fixing mechanisms 300 are correspondingly arranged on both sides of the clearance groove 120 in the longitudinal direction. The longitudinal direction is perpendicular to the lateral direction. This can better press and fix the aluminum profile harmonica tube, and prevent the aluminum profile harmonica tube from shifting during the sawing process and affecting the sawing effect.
[0040] It is understood that in some embodiments, the table thickness of the frame 100 is 15-25mm, that is, the depth of the relief groove 120 is 15-25mm. The relief groove 120 can cover the upper part of the saw blade 200, so that only 8%-20% of the diameter of the saw blade 200 is exposed upwards. This can effectively protect the saw blade 200 and improve the sawing quality of the aluminum profile harmonica tube.
[0041] Reference Figures 1 to 3 In some embodiments, the upper surface of the frame 100 is provided with a baffle 130 located on one side of the processing position 110; the frame 100 is also provided with a second fixing mechanism 400, which includes a third transverse drive mechanism 420 and a second pressure block 410 connected by transmission. The second pressure block 410 is movably disposed on the side of the baffle 130 near the processing position 110. The third transverse drive mechanism 420 is installed on the frame 100 and can drive the second pressure block 410 to move in the transverse direction closer to or away from the baffle 130. Thus, the baffle 130 and the second pressure block 410 can cooperate to press and fix the aluminum profile harmonica tube from the side, further preventing the aluminum profile harmonica tube from shifting during the sawing process and affecting the sawing effect.
[0042] It is understandable that the second pressure block 410 can be made of rubber, silicone or other flexible materials, thereby avoiding damage to the aluminum harmonica tube caused by the second pressure block 410.
[0043] It is understandable that the third lateral drive mechanism 420 can specifically adopt a linear drive mechanism such as a cylinder or a linear push rod.
[0044] Reference Figures 1 to 3 In some embodiments, the upper end of the baffle 130 has an upwardly extending mounting plate 140, on which the first lateral drive mechanism 220 is mounted. This allows the baffle 130 to serve as both a limiting and fixing structure for restricting the movement of the aluminum profile harmonica tube and a mounting structure for the first lateral drive mechanism 220, achieving multiple uses in one device. The structure is simple and facilitates the installation layout of various components on the frame 100.
[0045] Reference Figures 1 to 3In some embodiments, the frame 100 is provided with a receiving groove 150 located on the side of the baffle 130 away from the processing position 110. The receiving groove 150 and the clearance groove 120 are arranged in the transverse direction and communicate with each other. The lower end of the baffle 130 is provided with a through groove 131 through which the upper end of the saw blade 200 passes in the transverse direction. The upper surface of the frame 100 is also provided with a first protective cover 160. The first protective cover 160 is located on the side of the baffle 130 away from the processing position 110. The first protective cover 160 abuts against the baffle 130 and covers the outer periphery of the through groove 131 and the receiving groove 150. Therefore, after the saw blade 200 completes the sawing work, it can pass through the through groove 131 of the baffle 130 in the transverse direction from the relief groove 120 and finally stop in the receiving groove 150. The first protective cover 160 can protect the saw blade 200 located in the receiving groove 150, and prevent the upper end of the saw blade 200 from being exposed to the outside and accumulating dust or causing damage or injury to the operator.
[0046] Reference Figure 1 In some embodiments, a feeding mechanism 500 is provided on one side of the frame 100. The feeding mechanism 500 includes a feeding frame 510 and multiple feeding rollers 520 rotatably mounted on the feeding frame 510. All the feeding rollers 520 are arranged sequentially at intervals along the longitudinal direction, thereby enabling the long aluminum profile harmonica tube to be transported along the longitudinal direction to the processing position 110 for sawing operations.
[0047] Reference Figures 1 to 4 In some embodiments, the sawing structure further includes a second protective cover 230 located below the frame 100 and with its opening facing upward. The saw blade 200 is partially rotatably mounted inside the second protective cover 230. The rotation shaft 201 of the saw blade 200 passes through the side wall of the second protective cover 230 and is connected to the rotation drive mechanism 210. The first lateral drive mechanism 220 is connected to the second protective cover 230 and can drive the second protective cover 230 to reciprocate in the lateral direction. This facilitates the rotational mounting of the saw blade 200, as well as the protection of the saw blade 200 and the driving of the saw blade 200 to move in the lateral direction.
[0048] Reference Figures 1 to 4 In some embodiments, a belt drive mechanism is provided between the rotary drive mechanism 210 and the saw blade 200. The belt drive mechanism includes a first pulley 240, a second pulley 250, and a belt (not shown in the figure). The first pulley 240 is located on the output shaft of the rotary drive mechanism 210, and the second pulley 250 is located on the rotating shaft 201. The belt is wound around the outer periphery of the first pulley 240 and the second pulley 250. This facilitates the installation layout between the rotary drive mechanism 210 and the saw blade 200, and also enables the saw blade 200 to rotate stably, thereby performing stable sawing work on the aluminum profile harmonica tube.
[0049] Reference Figure 4 In some embodiments, a slide rail 260 arranged in the lateral direction is provided below the frame 100. A slide block 270 is movably mounted on the slide rail 260. The rotary drive mechanism 210 and the second protective cover 230 are both mounted on the slide block 270. The first lateral drive mechanism 220 is connected to the slide block 270 and drives the slide block 270 to move laterally along the slide rail 260, thereby realizing the stable lateral movement of the saw blade 200.
