Description

Technical Field

[0001] The utility model relates to the technical field related to mechanical engineering, and in particular to a laser cutting device for producing air ducts. Background Art

[0002] An air duct is a pipe used in ventilation, air conditioning, HVAC and other systems to transport air, gas or other fluids. It is widely used in construction, industry, automobiles and other fields. At the same time, buildings or equipment have specific requirements for the size and shape of the air duct. Cutting can adjust the air duct to the appropriate length and shape according to actual needs. Traditional cutting methods (such as manual cutting or mechanical cutting) are often slow and cannot meet the needs of large-scale production. Laser cutting can significantly increase the cutting speed and improve production efficiency. The emergence of laser cutting devices for the production of air ducts is to meet the high requirements of modern manufacturing in terms of efficiency, quality, flexibility and environmental protection. Through laser cutting technology, enterprises can achieve higher production capacity and lower production costs to meet the ever-changing needs of the market.

[0003] According to the retrieval of China Utility Model Publication No.: CN221620960U, a cutting device for producing air ducts is disclosed. The cutting device for producing air ducts clamps the inner wall of the air duct through a clamping mechanism, so that the position of the air duct remains fixed. At the same time, the clamping mechanism can be suitable for air ducts with different cross-sectional shapes, such as rectangular and circular air ducts, and can be clamped. It has a wide range of applications. The stepping motor can drive the outer gear ring to rotate through the gear, thereby driving the turntable to rotate, and then driving the air duct on the clamping mechanism to rotate, which is convenient for cutting the air duct. The cutting device for producing air ducts uses a servo motor A to drive the threaded rod to rotate back and forth, thereby driving the cutting mechanism above the cylinder to move back and forth through the slider, so that air ducts of different lengths can be cut. The moving mechanism is used to drive the cutting mechanism to move back and forth, so as to completely cut the side wall of the air duct. At the same time, the position of the vertical plate on the right side can be adjusted, so that the clamping mechanisms on both sides can clamp air ducts of different lengths.

[0004] However, when implementing the above technical solution, the following problems exist: when the device is in use, the clamping mechanism of the device is limited by the area of ​​the vertical plate and can only clamp air ducts that are smaller than the area of ​​the vertical plate. If the thickness of the air duct is larger than the area of ​​the vertical plate, it cannot be fixed, resulting in a small scope of application. At the same time, the cutting device uses traditional blades and manual measurement of the cutting position, which will lead to low cutting efficiency and inaccurate cutting precision.
