Description

Technical Field

[0001] This utility model belongs to the field of air conditioning system technology, specifically, it relates to a multi-angle cutting device for duct processing. Background Technology

[0002] In the field of air conditioning systems, air ducts play an irreplaceable role as key components for gas transportation. The processing quality of air ducts directly affects the operating efficiency, stability, and safety of the entire system. The cutting process, as an important link in the air duct processing, has a decisive impact on the final quality of the air duct in terms of its precision and efficiency.

[0003] Currently, traditional duct cutting methods mainly rely on manual operation using simple cutting tools, such as manual cutting machines. Manual operation makes it difficult to guarantee the accuracy of the cutting angle, especially when multi-angle cutting is required. Deviations in the cutting angle can seriously affect the connection and sealing of the duct to other components and the compatibility of installation. With the gradual development of technology, some mechanized duct cutting equipment has appeared on the market. However, these devices usually lack effective positioning auxiliary devices, and operators mainly rely on experience to judge the cutting position. This inevitably leads to deviations in the cutting position, affecting the processing accuracy of the duct and thus the performance of the entire ventilation system. To address this, we propose a multi-angle cutting device for duct processing. Utility Model Content

A first motor 6 is installed on one side of the fixing frame 5, and a cutting blade 7 is fixedly sleeved on the outer wall of the output shaft of the first motor 6. The support plate 11 is slidably connected to the top of the base plate 1. A fixing component for fixing the duct is provided at the top of the support plate 11. A laser lamp 23 is installed on the inner wall of the bracket 3, and an L-shaped pointer 21 is installed on the outer wall of the bracket 3. A scale 22 is formed on the outer wall of the arc-shaped support plate 2, and the needle of the L-shaped pointer 21 is positioned in front of the scale 22.

[0016] Furthermore, a rotating shaft 9 is installed at the output end of the second motor 8. The rotating shaft 9 extends through the front of the base plate 1 into the rotating groove 10, and the rotating shaft 9 is rotatably connected to the base plate 1 through a bearing. The bracket 3 is fixedly sleeved on the outer wall of the rotating shaft 9.

[0017] Among them, by setting a rotating shaft 9, the motor 8 can drive the bracket 3 to rotate through the rotating shaft 9.

[0018] Furthermore, the fixing assembly includes a fixing frame 16 and a pressure plate 17. The top of the pressure plate 17 is rotatably connected to a screw 18 via a bearing seat. The screw 18 is threadedly connected to a threaded hole at the top of the fixing frame 16. A knob 19 is installed at the top of the screw 18. A limit rod 20 is installed at the top of the pressure plate 17. The limit rod 20 moves through the top of the fixing frame 16.

[0019] By setting a limiting rod 20, the limiting rod 20 can limit the pressure plate 17, ensuring the stability of the pressure plate 17 during use.

[0020] Furthermore, a T-shaped sliding plate 12 is installed at the bottom of the support plate 11, and a T-shaped sliding groove 13 is opened at the top of the base plate 1. The T-shaped sliding plate 12 and the T-shaped sliding groove 13 are slidably connected. An adsorption plate 14 is installed at the top of the base plate 1, and the support plate 11 is engaged with the top of the adsorption plate 14. The support plate 11 is slidably connected with the outer wall of the adsorption plate 14. Magnetic seats 15 are fixedly embedded on both sides of the support plate 11, and the magnetic seats 15 are magnetically connected with the adsorption plate 14.

[0021] The magnetic base 15 can be attached to the adsorption plate 14 by setting the magnetic base 15, thereby fixing the support plate 11 on the base plate 1. The adsorption plate 14 is made of iron.

[0022] Furthermore, a limiting rod 24 is installed on the outer wall of the fixing frame 5, and the limiting rod 24 moves through the top of the bracket 3.

[0023] Among them, by setting the limiting rod 24, the fixing frame 5 can be limited, thereby improving the stability of the fixing frame 5 during use.

[0025] The bracket 3 can be limited by setting the limiting arc plate 25, thereby improving the stability of the bracket 3 during use.

[0026] The operating principle of a multi-angle cutting device for duct processing is as follows: In use, the duct to be cut is placed on the support plate 11. Then, by rotating the knob 19, the knob 19 drives the screw 18 to rotate, which in turn moves the pressure plate 17 downwards, thus pressing and fixing the duct. Next, the motor 8 is started, driving the rotating shaft 9 to rotate. The rotating shaft 9 drives the bracket 3 to rotate, which in turn drives the electric cylinder 4 to rotate. The electric cylinder 4, through the fixing frame 5, drives the cutting blade 7 to rotate, thereby adjusting the cutting angle of the cutting blade 7. The laser lamp 23 follows the rotation of the fixing frame 5. After the angle adjustment is complete, the support plate 11 is moved, causing the support plate 11 to move the duct through the fixing components. The laser lamp 23 is observed illuminating the duct. The cutting position is determined by the location on the duct. Then, the magnetic base 15 is activated, allowing it to adhere to the adsorption plate 14 and fix the support plate 11. The starting motor 6 is then activated, which drives the cutting blade 7 to rotate. The electric cylinder 4 is then activated, causing the fixing frame 5 to move downwards. The fixing frame 5 then moves the cutting blade 7 downwards, ultimately bringing the cutting blade 7 into contact with the duct, thus performing the cutting operation. This structure allows for easy cutting of the duct at multiple angles. The fixing components and magnetic base 15 facilitate adjustment of the duct's fixed position on the base plate 1. The laser light 23 helps to pinpoint the cutting position, ensuring accuracy and practicality.
