Technical Advantages of High Frequency Welded Pipe Forming Roller

Technical advantages of high frequency electric resistance welding pipe (erw steel pipe) forming roller row is following below:

(1) Reducing the number of rough roll forming, reducing the cost of the roll and roll change time. Row roll forming technology of crude molding machine generally consists of two horizontal roller racks with many inner and outer row roller for all pipe dimensions within the range of products, the first rack roll Normally only a single set, but roll and roll within the second frame you need to have several sets. This roll forming machine is reduced compared to the number of rolls, the investment had been reduced accordingly.

(2) Improving the quality of the pipe. By a number of small-diameter discharge roll instead of roll forming machine large-diameter horizontal rolls, roll surface speed difference is reduced, improving the steel edge stretching action to improve the quality of the pipe side portions.

(3) Reducing the roll change time and improve productivity. Rough shaping rolls and rolls Despite several sets of inner row, but not to replace the pipe with a diameter of each roll change is necessary. Precision machine and sizing machine is widely used and so rigid frame and quick-change device, roll change greatly shorten the time from the previous 1 to 2 classes a few tens of minutes. Roll change time is shortened, increased production, and therefore row roll forming technology has not only gained popularity in diameter pipe production, but also in the small-diameter pipe production has also been promoted. It can be said after the mid-1980s, is a row of roll forming technology development period.
