Aluminium tube production line
1. Production line overview
This aluminium tube production line is special equipment for making hollow glass aluminum tubes. It takes aluminum strip as raw material to produce hollow glass aluminum tube of required specifications by using cold roll forming and high frequency welding methods. This line adopts advanced roll forming technology to ensure stable running, easy to operating and maintaining. It reaches the advanced level in structure and accuracy among the industry.

3. Production flow
Raw material (aluminum strip coil) - Material uncoiling - Feeding and direction guiding - Roll forming - High frequency welding - Welding burr removing - Water cooling - Size adjusting - Straightening - Saw cutting - Tube unloading - Tube packing - Checking and collecting
4. Main equipment
Used to support aluminum strip coil and uncoil it.
It can provide raw materials for the production line.
1) Structure type
Double working position
2) Coil width
3) Coil outer diameter
4) Coil inner diameter
5) Center height
6) Weight bearing
2).Forming and sizing mill
It is used to roll the aluminum strip to form into tube shape and weld it. It takes the skin effect and proximity effect of high frequency current to make the current highly concentrated on two edges of aluminum strip so that the two strip edges are quickly heated to welding temperature and welded together by extruding roller. It becomes required aluminum tube after water cooling, size adjusting, straightening and cutting. The main machine is composed of forming part, welding part and sizing part.
One lathe bed for forming and sizing part.
Independent transmission for forming and sizing part.
Forming part: Feeding and direction guiding - 12 Horizontal rolling frames
|Welding part: Direction guiding - Extruding - 2 Welding burr removing - Water cooling|
|Sizing part: 5 Horizontal rolling frames - Speed measuring - 2 Straightening|
3) Transmission method
Two 11Kw DC motor transmit power to gear box through reducer, then gear box transmit power to each horizontal frame through universal transmission shaft. It has the advantages of high transmission efficiency, convenient maintenance and replacement, and also overload protection function for horizontal frames.
Used to install horizontal rollers by taking gantry type integral frame. The height of down roller is no need to be adjusted, the height of the bottom line of roll forming is ensured by the high precision of the machine and the high precision adjusting pad. The height of the upper roller shaft can be adjusted by the nut of the machine frame.
Horizontal roller shaft diameter Φ30mm, material 40Cr, quenching and tempering treatment, surface high frequency treatment.
The gear box is composed of a pair of spiral bevel gears and helical gears. Bevel gear material 20CrMoTi, carburizing and quenching treatment.
3). Cutting saw
It isUsed to roll the aluminum strip to form into tube shape and weld it. It takes the skin effect and proximity effect of high frequency current to make the current highly concentrated on two edges of aluminum strip so that the two strip edges are quickly heated to welding temperature and welded together by extruding roller. It becomes required aluminum tube after water cooling, size adjusting, straightening and cutting. The main machine is composed of forming part, welding part and sizing part.
1) Structure type
Controlled by PC program
Tracking and cutting to required length
2) Error in length
3) Cutting motor power
4) Driving motor power
4). Automatic unloading table
It isUsed to conveying aluminum tubes cut by the saw.
5) High frequency welder
It is Used to weld the aluminum tubes. This machine is a high frequency induction heating device of high efficiency and energy saving. It has advantages of high efficiency, simple and reliable circuit, convenient operation so it not only improve the production process and the quality of products, but also has energy saving effect. The complete equipment is composed of rectifier cabinet, speed control cabinet, inverter cabinet, transformer, operating platform, and wind-water cooling system. The solid state high frequency welder is designed according to the continuous running, and the integrated control and fault diagnosis function of the welding machine is realized by PLC programmable control system. The characteristics of solid state high frequency heating system: simple circuit, convenient installation and convenient maintenance, complete protection, harmonic interference is small, does not pollute the power grid safety, high pressure sensors on the aluminum ignition high efficiency, obvious energy saving, cooling water consumption, no welding spatter, good welding quality.
It is Used to roll form the aluminum tubes. It can form the tube blank by the pressure generated by rollers. By taking the principle of reasonable design, high precision NC machining and vacuum quenching, it has the characteristics of high precision, reasonable forming and long service lifetime.
