Description

Technical Field

[0001] This utility model relates to the field of HVAC engineering technology, specifically to a HVAC pipe cutting device for HVAC engineering. Background Technology

[0002] In the field of HVAC engineering, pipe installation and laying are crucial steps. Traditional HVAC pipe cutting techniques have many problems. For example, common manual cutting methods are inefficient, consuming a lot of manpower and time, and the cutting accuracy is difficult to guarantee, easily resulting in uneven cuts and dimensional deviations. This can adversely affect the subsequent pipe connection and sealing, increasing the risk of water and air leaks and affecting the overall performance and stability of the HVAC system. At the same time, some mechanical cutting equipment is complex to operate, requires highly skilled operators, and generates significant noise and dust pollution during the cutting process, which is detrimental to the environment and personnel health at the construction site. Therefore, there is an urgent need for a more efficient, precise, and environmentally friendly pipe cutting technology.

[0003] Before use, HVAC pipes need to be cut. The traditional cutting method is for workers to manually cut the HVAC pipes using a cutting machine. However, it is impossible to guarantee the flatness of the cut during the cutting process, and another worker is needed to help fix it. The cutting process of HVAC pipes is time-consuming and laborious, which brings inconvenience and increases the cutting time. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, when cutting HVAC pipes, involves placing the pipe to be cut on top of an arc-shaped support plate, then using an arc-shaped clamping plate to clamp and fix the pipe. A small electric cylinder drives the laser cutting head downwards to contact the surface of the HVAC pipe. The drive motor then starts, causing the transmission column to rotate.

The rotating gear ring drives the fixing frame, the small electric cylinder, and the laser cutting head to rotate and move, thus cutting the HVAC pipe. This provides the advantage of facilitating HVAC pipe cutting, allowing for quick and automatic circular cutting of HVAC pipes, and reducing the cutting time.
