HSS Cold Saw Machine Use ERW Tube Mill Machine
It is the mechanical equipment which used in continuously production, auto fixed ruler cutting steel pipes, is one of the important support device for weld pipe production line. It can cut pipes during static and motion status, can both cut round pipe and special pipe.
Flying cold sawing is a new online cutting technology in H.F. welded tube industry. Compare with the friction heat saw, its most major characteristic is the cold milling principle. The end of the tube is smooth and without burr after cutting off. For high quality requirements, these is no need off-line second treatment. In addition, due to the use of servo tracking technology, cutting length accuracy is higher than the traditional computer flying saw. Dust and noise pollution are obviously reduced in the production process.
The technical flow of the production line:
{SteelTape}→→ Double-head un-coiler →→Strip-head Cutter and welder→→Spiral accumulator→→Forming section (Flattening unit +Main driving unit +Forming unit +Guide unit +High frequency induction welding unit +squeeze roller) + De-burr frame →→Cooling unit →→ Sizing unit and straightener →→Cold saw under computer-control →→ Run-out table→→ Semi-auto Packing machine
