Description

Technical Field

[0001] This utility model belongs to the field of cutting technology, specifically relating to an air conditioning duct cutting device. Background Technology

[0002] During the installation and commissioning of air conditioning systems, duct cutting is a crucial step to ensure accurate duct dimensions and tight connections. Precise cutting ensures the airtightness of the duct system and the uniformity of airflow distribution, thereby improving the overall performance of the air conditioning system.

[0003] Problems with existing technology:

[0004] Traditional duct cutting devices typically require the duct to be fixed in place before cutting it with a cutting blade. However, when dealing with thicker ducts, workers often need to readjust and fix the duct, which is not only cumbersome but also increases labor intensity, leading to a decrease in duct cutting efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an air conditioning duct cutting device that allows the cutting blade to rotate around the duct and then cut the duct by rotating itself, thereby improving cutting efficiency, avoiding the hassle of repeatedly fixing the duct, and reducing labor intensity.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An air conditioning duct cutting device includes a first workbench, a second workbench is provided on the outside of one side of the first workbench, a cutting slit is formed between the second workbench and the first workbench, a toothed ring is fixed on one side of the second workbench and located in the cutting slit, a rotating ring is rotatably mounted on one side of the toothed ring, a double-headed motor is provided on the outer wall of the rotating ring, and a gear that meshes with the toothed ring is fixed on the output shaft of the double-headed motor.

[0008] A mounting plate is fixed to one side of the rotating ring. Two symmetrical grooves are opened on one side of the mounting plate. A slider is slidably installed inside the groove. An adjusting wheel is rotatably installed on one side of the slider. A first hydraulic cylinder is provided on the outer wall of the middle part of the mounting plate. A mounting block is fixed to the output shaft of the first hydraulic cylinder. A connecting rod rotatably connected to the mounting block is rotatably installed on the outer wall of the slider. A mounting shaft is rotatably installed through one side of the mounting block. A driven wheel is fixed to one end of the mounting shaft. A synchronous belt is provided between the adjusting wheel and the driven wheel. A driving wheel that cooperates with the synchronous belt is provided on the output shaft of the dual-head motor. A cutting blade is provided at the other end of the mounting shaft. A clamping mechanism for clamping the air duct is provided on the top of both the first worktable and the second worktable.

[0009] The clamping mechanism includes support plates symmetrically arranged on the top of the first worktable and the second worktable. A second hydraulic cylinder is fixed to the top of the support plate, and an arc-shaped clamping plate is fixed to the output shaft of the second hydraulic cylinder.

[0010] One side of the slider is fixed with a spring that is fixed to the inner wall of the groove.

[0011] The bottom of the first and second worktables is provided with an integrated support leg.

[0012] Two guide rods are provided on one side of the arc-shaped clamping plate, and the outer wall of the second hydraulic cylinder is provided with a fixing lug that is slidably connected to the guide rods.

[0013] The technical effects achieved by this utility model are as follows:

[0014] The cutting blade of this invention is driven by a dual-head motor to rotate a drive wheel and a gear. The drive wheel, through the cooperation of a synchronous belt and an adjusting wheel, causes the driven wheel to rotate. The driven wheel, through a mounting shaft, drives the cutting blade to rotate. Simultaneously, as the gear rotates, it engages with a gear ring, causing a rotating ring to rotate. The rotating ring then causes the cutting blade to rotate around the duct. Finally, the first hydraulic cylinder is activated, which moves the mounting block. The mounting block then moves the cutting blade on the mounting shaft closer to the duct, cutting it. The structure is simple and easy to operate. By having the cutting blade rotate around the duct and then cut it through its own rotation, the cutting efficiency is improved, the hassle of repeatedly fixing the duct is avoided, and labor intensity is reduced.

[0015] The two adjustments in this invention, during the process of the first hydraulic cylinder pushing the mounting block, work in conjunction with the connecting rod to drive the slider to move relative to each other, and the slider to drive the adjusting wheel to move relative to each other, so that the synchronous belt can properly cooperate with the driven wheel and the driving wheel, thereby enabling the equipment to be used normally.

A mounting shaft is rotatably installed through one side of the mounting block 15. A driven wheel 17 is fixed to one end of the mounting shaft.

[0024] According to the above structure, when cutting the duct, the duct passes through the rotating ring 4 and is fixed on the first workbench 1 and the second workbench 2 by the clamping mechanism, so that the fixed position of the duct is located at the center of the rotating ring 4. Then, the dual-head motor 5 is started, which drives the driving wheel 7 to rotate. The driving wheel 7, through the cooperation of the synchronous belt 13 and the adjusting wheel 11, causes the driven wheel 17 to rotate. The driven wheel 17 drives the cutting blade 18 to rotate through the mounting shaft. At the same time, the dual-head motor 5 drives the gear 6 to rotate. The gear 6 cooperates with the gear ring 3 to drive the rotating ring 4 to rotate. The rotating ring 4 drives... The cutting blade 18 rotates around the duct, and finally the first hydraulic cylinder 14 is activated. The first hydraulic cylinder 14 drives the mounting block 15 to move, and the mounting block 15 drives the cutting blade 18 on the mounting shaft to move closer to the duct and cut the duct, thus improving the duct cutting efficiency. The two adjusting wheels 11, when the first hydraulic cylinder 14 pushes the mounting block 15, cooperate with the connecting rod 16 to drive the slider 10 to move relative to each other. The slider 10 drives the adjusting wheels 11 to move relative to each other, so that the synchronous belt 13 can cooperate normally with the driven wheel 17 and the driving wheel 7, thus enabling the equipment to be used normally.

The cooperation between the guide rod and the fixed ear makes the movement of the arc-shaped clamping plate 21 more stable.

[0027] The working principle of this utility model is as follows: When cutting the air duct, the air duct passes through the rotating ring 4 and is fixed on the first workbench 1 and the second workbench 2 by the clamping mechanism, so that the fixed position of the air duct is located at the center of the rotating ring 4. Then, the double-head motor 5 is started, which drives the driving wheel 7 to rotate. The driving wheel 7, through the cooperation of the synchronous belt 13 and the adjusting wheel 11, causes the driven wheel 17 to rotate. The driven wheel 17 drives the cutting blade 18 to rotate through the mounting shaft. At the same time, the double-head motor 5 drives the gear 6 to rotate. The gear 6 cooperates with the gear ring 3 to drive the rotating ring 4 to rotate. The rotating ring 4 drives the cutting blade 18 to rotate around the air duct. Finally, the first hydraulic cylinder 14 is started, which drives the mounting block 15 to move. The mounting block 15 drives the cutting blade 18 on the mounting shaft to move closer to the air duct and cut the air duct.
