Stable Square Tube Mill Pipe Making Electric Control Square Shape 80m / Min Mill Speed

Stable Square Tube Mill Pipe Making Electric Control Square Shape 80m / Min Mill Speed 
 
Equipment description
 
200x200mm Full automatic high speed High precision square tube mill line  
is the first full-automatic pipe making machine in china to meet the requirements of the international market, according to our company LW series unit combined with FF forming technology, developed the automatic square and rectangular tube equipment. The pipe making machine can produce a certain specification of opening cold bend steel, such as U,C section steel etc., width and height of the product can be adjusted infinitely. The steel making machine is used to scale to cut off the steel tubes, the incision level off, smooth, without burr, scale with high precision.
 
The pipe machine’s main characteristics of the equipment
 
1. In a very short period of time to finish the adjustment of the roller
2. producing the different specifications of the tube, only need to adjust
3. decreasing the number of workers, reduce the labor costs
4. improve the service life of the equipment.
5. The machine can be repaired alone.
 
Welded pipe making machine consists of the following parts
 
1. Forming parts: Consist of seven frame of horizontal roll stands, four stands of empty curving stands, four stands of vertical roll rack and one stand of feeding rack
2. Welding parts: consists of welding five roller of extruding roll, two frame of scraping scar rack and one frame of polish rack
3. Sharping parts: consists of four frame of four roller rack
4. Electric control part: controlled by multipoint PLC control
 

 
Production Process
 
Scroll up → Uncoil → Flattening → End Shear & Butt Welding → Accumulator → Forming → High-frequency induction welding→ Removing external burr → Cooling → Sizing → Cutting → Checking & Collecting → Accessing Warehouse
