Description

A cutting mechanism for spiral duct machine Technical Field

[0001] This utility model relates to the field of duct processing technology, specifically a cutting mechanism for a spiral duct machine. Background Technology

[0002] Spiral duct cutting mechanisms, as indispensable equipment in the duct manufacturing industry, primarily function to perform precise and accurate cutting of spiral ducts. However, traditional cutting mechanisms have revealed several significant shortcomings in practical applications.

[0003] In traditional cutting processes, manufacturers typically place the cutting machine at the bottom of the duct. When a cutting task is required, the servo cutting machine first moves vertically upwards, then moves synchronously with the duct to ensure the horizontality of the cut surface. However, this process presents a significant problem: due to the lack of necessary stabilizing structure during duct movement, burrs are likely to appear on the cut edges, thus affecting the overall quality of the duct.

[0004] More seriously, when the servo cutter rises vertically from the bottom to cut, the significant pressure generated upon contact with the duct exacerbates the formation of burrs. This not only affects the appearance quality of the duct but also poses a potential threat to its performance. Therefore, a cutting mechanism for spiral ductwork is proposed. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a cutting mechanism for spiral duct cutting machines, which has advantages such as reducing burrs during duct cutting and solving the problems of insufficient stability and easy burrs on the cutting edges of traditional cutting mechanisms when cutting spiral ducts.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned goal of reducing burrs during duct cutting, this utility model provides the following technical solution:

[0009] A cutting mechanism for a spiral duct machine includes a base, with a cylinder 1 installed at each of the four corners of the upper end of the base. The upper ends of the cylinder 1 are all supported by a lifting plate. A cutting mechanism for cutting ducts is installed inside the lifting plate. The cutting mechanism includes a sliding plate that slides inside the lifting plate, a cylinder 2 for pushing the sliding plate, and a servo cutting machine.

[0010] The base is also provided with a support mechanism, which includes a support frame and two arc-shaped slide rails fixed to the upper end of the support. Each arc-shaped slide rail spans the upper end of the air duct and has an arc-shaped groove.

[0011] At least two sets of stabilizing mechanisms that slide along the arc-shaped grooves are provided on the two arc-shaped slide rails.

[0012] The stabilizing mechanism includes a sliding sleeve, a square rod sliding within the sliding sleeve, and a stabilizing head located on the square rod near one end of the air duct.

[0013] The stabilizing head includes rollers that abut against the surface of the duct.

[0014] A preferred embodiment of this invention is that the cutting mechanism further includes a mounting plate fixed to the upper end of the sliding plate, and a rack plate parallel to the duct axis is provided in the middle of the upper end of the mounting plate.

[0015] The preferred technical solution of this utility model is that a sliding rod is fixed on the mounting plate located on both sides of the rack plate, and a driving mechanism that cooperates with the rack plate is slidably arranged on the two sliding rods. The driving mechanism is fixed to the servo cutting machine.

[0016] A preferred embodiment of this invention is that the sliding direction of the sliding plate is perpendicular to the axis of the air duct.

[0017] The preferred technical solution of this utility model is that the sliding direction of the square rod is perpendicular to the axis of the air duct.

[0018] The preferred technical solution of this utility model is that the stabilizing mechanism further includes a first bolt and a second bolt. The first bolt passes through the arc-shaped groove and is threadedly connected to the sliding sleeve. The second bolt is threadedly connected to the sliding sleeve and passes through the sliding sleeve to abut against one side of the square rod.

[0019] A preferred embodiment of this invention is that the first bolt is provided with an anti-slip ring that contacts the arc-shaped slide rail.

[0020] A preferred embodiment of this invention is that a handle is fixedly installed at the upper end of each of the square rods.

[0021] The preferred technical solution of this utility model is that the stabilizing head further includes a support head and an adjusting disc. An adjusting chamber is opened at the section of the square rod near the air duct. The upper end of the support head passes through the square rod and communicates with the adjusting chamber. The adjusting disc is located in the adjusting chamber and is threadedly connected to the support head. The bottom of the support head is rotatably connected to a roller.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, this utility model provides a cutting mechanism for a spiral duct machine, which has the following advantages:

[0024] The cutting mechanism of this spiral duct cutting machine uses the lifting function of cylinder one to flexibly adjust the height of the servo cutter, adapting to ducts of different sizes and achieving precise cutting. Cylinder two pushes the sliding plate to move horizontally, avoiding the enormous pressure generated by vertical cutting, effectively reducing burrs on the duct and improving cutting quality.

[0025] The added stabilizing mechanism, with rollers pressed tightly against the duct surface, significantly improves cutting stability, reduces cutting errors caused by shaking, ensures smooth edges on the finished duct, and enhances overall quality.

[0026] By adjusting the threaded connection between the disc and the support head, the mechanism can flexibly adjust the direction of the rollers to ensure that they are aligned with the rotation direction of the air duct, further enhancing stability, providing solid support for cutting operations, and ensuring cutting accuracy.

Therefore, they should not be construed as limitations on this utility model.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] Please refer to Figure 1. A cutting mechanism for a spiral duct machine includes a base 1. Cylinder 3 is provided at each of the four corners of the upper end of the base 1. The upper end of the cylinder 3 is supported by a lifting plate 2. A cutting mechanism 4 for cutting duct 8 is provided inside the lifting plate 2.

[0040] Please refer to Figure 2. The cutting mechanism 4 includes a sliding plate 41 that slides within the lifting plate 2, a cylinder 42 for pushing the sliding plate 41, and a servo cutting machine 47.

[0041] Please refer to Figure 3. The base 1 is also provided with a support mechanism 5. The support mechanism 5 includes a support frame 51 and two arc-shaped slide rails 52 fixed on the upper end of the support frame 51. Each arc-shaped slide rail 52 spans the upper end of the air duct 8 and has an arc-shaped slide groove 53.

[0042] At least two sets of stabilizing mechanisms 6 that slide along the arc-shaped groove 53 are provided on the two arc-shaped slide rails 52.

[0043] Please refer to Figures 4-5. The stabilizing mechanism 6 includes a sliding sleeve 61, a square rod 62 that slides within the sliding sleeve 61, and a stabilizing head 63 located on the square rod 62 near one end of the air duct 8.

[0044] Please refer to Figure 8. The stabilizing head 63 includes a roller 633, which abuts against the surface of the duct 8.

[0045] It should be noted that the rear end of the duct 8 is equipped with a support frame 7 for supporting the duct 8, and the rollers 633 are made of rubber to provide flexible support for the duct 8.

[0046] In this embodiment, the cutting mechanism 4 also includes a mounting plate 43 fixed to the upper end of the sliding plate 41, and a rack plate 44 parallel to the axis of the air duct 8 is provided in the middle of the upper end of the mounting plate 43.

[0047] It should be noted that the design of the rack plate 44 enables the drive mechanism 46 to move along a specific path (i.e., in a direction parallel to the axis of the air duct 8), which helps the servo cutter 47 maintain linear motion when performing cutting tasks, further improving the cutting accuracy 6.

[0048] In this embodiment, sliding rods 45 are fixed on the mounting plates 43 located on both sides of the rack plate 44, and driving mechanisms 46 that cooperate with the rack plate 44 are slidably arranged on the two sliding rods 45. The driving mechanisms 46 are fixed to the servo cutting machine 47.

[0049] It should be noted that the drive mechanism 46 contains a rotating gear or rack drive device (not shown in the figure), which, in conjunction with the rack plate 44, ensures the precise movement of the servo cutter 47. This design allows the servo cutter 47 to make precise position adjustments 6 according to a preset program during the cutting process.

[0050] In this embodiment, the sliding direction of the sliding plate 41 is perpendicular to the axis of the air duct 8.

[0051] It should be noted that cylinder 42 pushes the sliding plate 41 to move horizontally, and this action is performed after the lifting plate 2 has been adjusted to the appropriate height. This horizontal movement method avoids the enormous pressure that may be caused by traditional vertical cutting, thereby reducing the generation of burrs.

[0052] In this embodiment, the sliding direction of the square rod 62 intersects perpendicularly with the axis of the air duct 8.

[0053] It should be noted that by sliding the square rod 62, the stabilizing head 63 can be moved closer to or further away from the duct 8, which is suitable for stabilizing ducts 8 of different sizes.

[0054] Please refer to Figure 6. In this embodiment, the stabilizing mechanism 6 also includes a first bolt 64 and a second bolt 65. The first bolt 64 passes through the arc-shaped groove 53 and is threadedly connected to the sliding sleeve 61. The second bolt 65 is threadedly connected to the sliding sleeve 61 and passes through the sliding sleeve 61 to abut against one side of the square rod 62.

[0055] It should be noted that the sliding of the square rod 62 within the sliding sleeve 61 allows the stabilizing head 63 to be finely adjusted according to the actual position of the duct 8. The second bolt 65 is used to lock the position of the square rod 62, ensuring the stability of the stabilizing head 63 during the cutting process.

[0056] Please refer to Figure 7. In this embodiment, the first bolt 64 is provided with an anti-slip ring 641 that contacts the arc-shaped slide rail 52.

[0057] It should be noted that the first bolt 64 not only fixes the position of the sliding sleeve 61 on the arc-shaped slide rail 52, but also increases the friction between the anti-slip ring 641 and the arc-shaped slide rail 52, preventing the stabilizing mechanism 6 from accidentally sliding during the cutting process.

[0058] Please refer to Figures 4-5. In this embodiment, a handle 66 is fixedly installed on the upper end of each square rod 62.

[0059] It should be noted that the addition of handle 66 makes it easier for users to operate the stabilizing mechanism 6, especially when it is necessary to slide the stabilizing mechanism 6 along the arc-shaped slide 53, and when adjusting the distance between the stabilizing head 63 and the air duct 8.

[0060] Please refer to Figure 8. In this embodiment, the stabilizing head 63 also includes a support head 631 and an adjusting disc 632. An adjusting chamber 621 is provided on the section of the square rod 62 near the air duct 8. The upper end of the support head 631 passes through the square rod 62 and connects to the adjusting chamber 621. The adjusting disc 632 is located in the adjusting chamber 621 and is threadedly connected to the support head 631. The bottom of the support head 631 is rotatably connected to the roller 633.

[0061] It should be noted that since the duct 8 is made of thin sheet metal spirally pressed together during the manufacturing process, by adjusting the threaded connection between the disc 632 and the support head 631, the user can easily adjust the rotation angle of the support head 631, thereby adjusting the rotation direction of the roller 633 to ensure that it is consistent with the rotation direction of the duct 8, so as to adapt to the duct 86 with different rotation speeds.

[0062] In summary, the cutting mechanism of this spiral duct cutting machine, through the lifting function of cylinder 3, flexibly adjusts the height of the servo cutter 47 to adapt to ducts 8 of different sizes, achieving precise cutting. Cylinder 2 42 pushes the sliding plate 41 to move horizontally, avoiding the enormous pressure generated by vertical cutting, effectively reducing burrs on the duct 8, and improving cutting quality.

[0063] The added stabilizing mechanism 6, with rollers 633 closely attached to the surface of the duct 8, significantly improves cutting stability, reduces cutting errors caused by shaking, ensures smooth edges of the finished duct 8, and improves overall quality.

[0064] By adjusting the threaded connection between the disc 632 and the support head 631, the mechanism can flexibly adjust the direction of the roller 633 to ensure that it is consistent with the rotation direction of the air duct 8, further enhancing the stability effect, providing solid support for the cutting operation, and ensuring cutting accuracy.

[0065] Working principle: When it is necessary to cut the air duct 8, the height of the lifting plate 2 is first adjusted by cylinder 3 so that the servo cutter 47 reaches the appropriate cutting position. Then, cylinder 42 pushes the sliding plate 41 to move horizontally to cut the air duct 8 from the side, while the servo cutter 47 moves along the preset cutting path. At the same time, the stabilizing mechanism 6 provides necessary support and stability by using rollers 633 to closely adhere to the surface of the air duct 8, reducing cutting errors caused by the shaking of the air duct 8.

[0066] During the cutting process, the cooperation between the drive mechanism 46 and the rack plate 44 ensures the precise movement of the servo cutter 47. The user can adjust the distance between the stabilizing head 63 and the duct 8 by rotating the second bolt 65 to accommodate ducts 8 of different shapes and sizes. The user can adjust the stabilizing mechanism 6 by rotating the first bolt 64, allowing it to move along the arc-shaped groove 53 to adjust the duct 8 to the required stable position according to actual needs. Additionally, the user can adjust the rotation angle between the support head 631 and the square rod 62 by rotating the adjusting disc 632, allowing the roller 633 to adapt to ducts 89 with different rotation speeds.

[0067] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
