Description

[0002] The high-efficiency laser cutting robot for metal pipe fittings is a high-precision and high-efficiency automatic robot device, mainly used for continuous cutting of various metal pipe fittings. This device uses a high-energy-density laser beam to irradiate the material surface, causing the material to rapidly melt or vaporize, thereby achieving the purpose of cutting. Laser cutting technology has been widely used in the metal processing industry due to its fast cutting speed, high precision, and small heat-affected zone.

[0003] There are many types of metal pipe fittings, among which semicircular pipe fittings are particularly common and are used in fields such as drainage, industrial production, and construction. For harsh application scenarios, thicker round pipes are generally used to make semicircular pipe fittings.
