Technical Field

[0001] This utility model relates to the technical field of wire bending head welding device, and in particular to a wire bending head welding device with positioning and material removal functions. Background Technology

[0002] During the installation of metering instruments such as gas meters and water meters, the pipe connection behind the instrument is a crucial step. This typically requires a pre-bent pipe fitting (commonly known as a pipe bend) to be securely connected to the gas or water outlet of the instrument. To ensure the sealing and reliability of the connection, welding techniques (such as brazing) are commonly used.

[0003] In existing technologies, most wire bending welding devices are either single-function or structurally fragmented, relying on manual experience for positioning, resulting in low efficiency and poor accuracy, leading to unstable welding quality. Furthermore, processes such as extrusion, shaping, end finishing, and welding often require multiple machines or repeated manual operations, making the process cumbersome and severely restricting production efficiency.
