Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a semi-automatic copper pipe cutting device for air conditioner installation. Background Art

[0002] The copper tube of the air conditioner plays a key role in the refrigeration cycle, and is mainly responsible for transmitting the refrigerant. The copper tube ensures the normal circulation of the refrigerant in the air conditioning system, forming a closed circulation system. When using a special copper tube to connect the internal and external units, refrigerant leakage can be avoided, thereby ensuring the cooling effect of the air conditioner. In the refrigeration cycle, the copper tube allows the refrigerant to flow in different refrigeration components, completing the transformation from gas to liquid, thereby realizing the refrigeration function of the air conditioner.

[0003] When installing an air conditioner, if the copper tube is too long, resulting in excess parts in the tube, in order to avoid damage to the copper tube due to collision or friction, causing the air conditioner to be unusable, the excess parts need to be cut. At the same time, cutting off the excess copper tube can reduce the exposure of the copper tube, which is not only beautiful and tidy, but also can reduce the resistance of the piping system and improve the operating efficiency of the air conditioning system. However, after cutting the copper tube, the diameter of one end of the cut copper tube will become smaller or deformed.

[0004] Therefore, a semi-automatic cutting device for copper pipes used for air-conditioning installation is proposed. Utility Model Content
