Description

Technical Field

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

[0002] Heating, ventilation, and air conditioning (HVAC) engineering is an integrated technology system for heating, ventilation, and air conditioning systems in building environments. It regulates indoor temperature, humidity, airflow, and air quality to ensure human comfort and meet industrial production needs. It encompasses applications of thermodynamics and fluid mechanics, involving equipment selection, piping layout, energy optimization, and intelligent control, spanning the entire lifecycle of design, construction, commissioning, and operation and maintenance. As a core branch of building engineering, its functions include multiple objectives such as environmental control, fire protection and smoke extraction, and energy conservation and emission reduction.

[0003] In HVAC engineering, pipe laying is a lengthy process, making pipe cutting and assembly crucial steps. For example, a pipe cutting device (publication number CN219766941U) has an adjustable support structure to accommodate pipe diameters, providing stable support for pipes of varying sizes. However, this technology is unstable. When cutting long pipes with the cutting end on one side, the pipe may tilt or lift on the cutting device. Cutting under these conditions results in an angle between the cutting surface and the pipe's axis, causing the cut surface to be tilted and complicating subsequent assembly. Utility Model Content

Two sets of adjustment structures are installed on the upper wall of the support platform 1, and two sets of pipe support structures are respectively installed on the upper walls of the two sets of adjustment structures. Two sets of fixing structures are installed on the upper wall of the support platform 1.

On the upper wall of the support platform 1, the adjusting screw 4 is installed inside the adjusting frame 3 via bearings, and the adjusting slide rod 5 is fixedly installed inside the adjusting frame 3. The adjusting screw 4 has two sections of thread with the midpoint as the dividing line, and the rotation directions of the two sections of thread are opposite. Two adjusting sliding tables 6 are respectively movably fitted outside the adjusting screw 4 and the adjusting slide rod 5, and the two adjusting sliding tables 6 are respectively threadedly connected to the two sections of thread of the adjusting screw 4 via threads. The upper wall of the support platform 1 is provided with a relief groove 13, the lower wall of the fixing block 12 is an arc surface, and the lower wall of the support platform 1 is provided with four heightening feet 14.

[0021] Working principle:

[0022] I. Preparations before use: The operator first connects the external AC power supply to this utility model to provide power to the cutting machine body 2. Next, the operator needs to make adaptive adjustments, adjusting the distance between the two pipe support rollers 9 according to the required pipe diameter. The distance should be two-thirds of the pipe's outer diameter. The specific adjustment steps are as follows: The operator rotates the adjusting screw 4 using a tool. The two sections of the adjusting screw 4 with opposite threads rotate, causing the two adjusting sliding tables 6 to move linearly and synchronously, either moving closer together or further apart, until the distance between them is two-thirds of the pipe's outer diameter.

[0023] II. Pipe Cutting: The operator places the pipe to be cut on the upper wall of the two sets of pipe support rollers 9. The operator then rotates the two sets of fixing screws 11 using a tool. Under the action of the threads, the fixing screws 11 move linearly, causing the fixing block 12 to move towards the pipe until the fixing block 12 fixes the pipe. At this point, the left and right sides of the end face of the pipe to be cut are fixed. The pipe is fixed at three points, ensuring the perpendicularity of the pipe's axis to the cutting surface, and ensuring that the cut end face of the pipe maintains a certain degree of perpendicularity to its axis.
