Copper Tube Flame Brazing Machine

Typical Y-joint copper manifolds can be welded by this flame brazing machine:

 

This machine is designed in graduated turn-table structure, adopting flame brazing technology for welding copper tubes together.

For Y-joint manifold welding, this machine will have 6 stations, each station has one fixture:

- Station 01: blank tube loading

- Station 02: inspecting

- Station 03: flame brazing one end

- Station 04: flame brazing another end

- Station 05: cooling

- Station 06: unloading

Flame Brazing Machine Buildup:

1) Main body, turn-table and protection cover

2) Two sets flame brazing systems

3) Three sets auto welding wire feeding systems

4) One set water cooling system

5) Six sets tube fixtures

6) PLC control system

7) Gas pressure adjusting controller

8) Smoke exhausting system

Main features of copper tube flame brazing machine:

- Only manual loading & unloading, other actions automatic

- Stainless steel tube fixtures, free from deformation under high temperature

- Heating & cooling stations auto detecting, only work when there is part on fixture

- Welding torches are fine adjustable in all directions for different size parts

- Welding wires are fed automatically

- Nitrogen gas outfiring, quick and reliable

- Patent gas intelligent control system, gas pressure, flow and heating time can be preset

- Complete safety and alarming, auto stopping gas supply
