Car Components 4 Stations Index Flame Brazing Machines For Aluminum Tube
Product information:
There are many machines with new creative ideas for in/out tube joint brazing, such as evaporators, heaters, condensers used in automobiles.
Principle:
The brazing process will be automatically controlled. Effective control of gas flow, brazing time and brazing position, so the brazing temperature and brazing pool can be well controlled, the stability and the consistency of the brazing quality can be ensured.
Equipment composition:
Working turntable and jigs and fixtures (4 stations, each station can install 1 set of jigs)
Gas flow control system
Automatic wire feeding mechanism
Rotational power and positioning mechanism
Air circuit cabinet and combustion system
Infrared temperature monitoring
Compressed air forced cooling
Electric control cabinet and PLC control system
Exhaust hood
Safety guarantee:
1 Gas Control Lines
Fuel gas pipelines are controlled by piloted pneumatic valve. The whole pneumatic system is separated with the electrical system to avoid the danger of electrical light. The fuel gas and oxygen gas pipelines have been done leak proof test and provided with flash-back arrestor.
2 Pressure Alarm
The various gas pressure shall be monitored. Fuel gas pressure has up limit and down limit alarm, other gas has the down limit alarm.
3 Nitrogen Extinguishing Fire
Fire extinguished by nitrogen can avoid flash-back deflagration.
5 Forced ventilation system
There is forced ventilation system in the cabinet and that make the cabinet keep safe working environment.
6 E-stop
There are E-stop pushbuttons in the operation and maintenance positions, the electrical and pneumatic system can be shut-off for emergency use.
Feature:
1. Special torch design for uniform heating
2. Automatic torch position change
3. Automatic falme change function
4. Automatic table rotation and positioning
5. Automatic wire feeding mechanism
Technical data:

Brazing Process and Station Arrangement
| Station 1 | Loading and unloading station, unload the brazed work piece from the jigs and load the work piece to be brazed on the jigs. |
| Station 2 | Preheating station, preheat the work piece. |
| Station 3 | Brazing station, heat the tube joint to the brazing temperature and finish brazing. When brazing time reaches the setting, the flame become weak fire, the brazing torches return back, the table is rotated. |
| Station 4 | Cooling station, cool the work piece by the compressed air or nitrogen |
