Molding method

1, solid bentSolid bending, as the name implies, is the compaction of bending, when the inner and outer rollers and the tube blank are compacted in both directions.

1) the advantages of solid bending are small rebound, accurate molding, and as long as the roll is accurate, the Angle molding R is more accurate.

2) the disadvantage of solid bending is the stretching/thinning effect.First, the real bending will produce a stretch at the bending point, and the stretching effect will shorten the longitudinal length of the bending line.Second, the metal at the real bend will be thinned by stretching.


2, The hollow steel tube

Empty bending is the bending moment formed by the unidirectional contact between the outer roller and the outer wall of the tube blank, which will cause the bending line to produce compression. The compression effect will make the bending line elongate lengthwise, and the metal at the bending point will accumulate and become thicker, which is the compression/thickening effect of empty bending.


1) the advantage of empty bending is that side length bending can be carried out when the actual bending cannot be carried out, such as the top/side side synchronous bending and finishing of square rectangular tube.Empty bend can also bend R<0.2t internal Angle without pipe wall fracture.


2) the disadvantage of air bending is that when the upper/side side is in sync with the air bending, because the upper and lower rollers produce pressure at the same time, the forming force is easy to exceed the critical point, resulting in side instability and concave, and will also affect the stable operation and forming quality of the unit.This is also the square rectangular tube and the circular tube air bending molding different characteristics.
