IMPORTANCE OF THE IRON AND STEEL IN TUBE PROCESSING, BENDING AND CALENDERING
The iron and steel is an essential technology for the processing of the tube. The most modern and advanced Laser Tube machines also allow the carrying out of 3D tube processing, that is the three-dimensional processing on straight tube bars.
For this reason, the Laser Tube has become an integral part of the bending and calendaring techniques and processes of tubes of all shapes and metal alloys.
It is fair to say that the introduction of the Laser Tube has made it possible to carry out tube processing that was unthinkable until a few decades ago.
IRON AND STEEL, WHAT IS IT?
The iron and steel tube is a laser machine capable of cutting and processing the tube - such as drilling - thanks to the amplification of light beams by means of the emission of electromagnetic radiation.
Laser technology has made great strides revolutionizing the world of metal tube processing. It was A. Einstein, at the beginning of the 1900s. Who laid the scientific foundations of the modern Laser Tube. When he explained the phenomenon of "stimulated emission", which is still the basis of the functioning of all lasers today.
However, the first machines capable of cutting metals with laser technology were produced only starting in 1960. Now that we have explained, in principle, what the iron and steel tube is, let's understand how it works.
HOW DOES THE IRON AND STEEL LASER-TUBE WORK?
The laser tube generates a beam of high-power electromagnetic radiation which increases the temperature of the metal tube until it melts and vaporizes. However, the Laser Tube not only allows you to cut the metal tube, but also to perform many ancillary processes for bending and calendaring the tube, such as:
- The drilling
- Making buttonholes
- The execution of inclined cutson the tube
- The ' engraving of written
- The marking
SECTIONS AND MATERIALS THAT CAN BE WORKED WITH THE NEW LASERTUBE
There are considerable advantages deriving from this important investment in iron and steel tube processing, in particular for bending and calendaring.
WORKABLE SECTIONS
The Tube Laser allows you to process tubes with larger sections than traditional tube cutting machines. Furthermore, the Laser Tube is suitable for cutting and processing tubes of any shape:
- Roundtubes
- Square / rectangulartubulars
- Ovaland elliptical tubes
- Special closed profiles
- Special open profiles
PROCESSING OF THE IRON AND STEEL TUBE
One of the peculiarities of the Laser tube concerns the processing of metal profiles. These unlike tubes or tubular, which have a round and square / rectangular section respectively. They have particular geometric shapes. Moreover, iron and steel tubes are usually produced for particular uses.
In the most varied sectors such as, to name a few, the construction of cabins for machines. Earthmoving, lighting systems, door frames or windows
With the Laser Tube it is possible to cut any section and shape of metal profile without the need to build specific equipment.
WHAT IS THE USE OF IRON AND STEEL TUBE?
The iron and steel tube Laser is used for cutting tubes of all the main metal alloys, such as for example.
- Steel pipes - Used for example for the production of agricultural machinery, carpentry, livestock
- Stainless steel pipes - used for the construction of industrial and thermal plants, but also food plants and heat exchangers
- Aluminum tubes - used for example for the production of furniture, lamps and inside subways and buses (windows, handrails)
GREATER PRODUCTION EFFICIENCY THANKS TO THE DOUBLE CHARGER
Modern iron and steel tube Lasers contain 2 loaders:
- One is used to load tube or profile bars with a length of more than 6 meters (up to 12 meters).
- The other allows you to load pipes up to 6 meters. This allows you to perform laser cutting on a series of tubes and at the same time load the tubes for the next job
Modern Laser Tubes also have “unloads” based on the length of the tube, which allow for simultaneous processing of tubes of different lengths.
OXYGEN AND NITROGEN: THE ASSISTANCE GASES FOR LASER CUTTING
To perform laser cutting in the best possible way, which occurs when a laser beam melts a material, it is necessary to use gases. It helps to eliminate residues and impurities. The unarmed gases that are useful for laser cutting are:
- O2- Oxygen
- N2- Nitrogen
WHAT ARE THE DIFFERENCES?
The first difference between these two gases is the cost. In fact, laser cutting with nitrogen generally costs more than laser cutting with oxygen. In addition, there are other important considerations to make when choosing laser cutting with oxygen and nitrogen, in particular with regard to:
- The thickness of the tube
- Cleaning the laser cutting
- The speed of the cutting process
As for the thickness, while with oxygen it is possible to laser cut iron and steel pipes with even high thicknesses - up to 15 mm. Here greater power therefore requires. Moreover, here nitrogen is useful for laser cutting of pipes.
WHAT ARE THE EFFECTS OF OXIDE RESIDUES?
The laser cutting cleaning is another important aspect to consider in the choice of gas for laser cutting. In fact, laser cutting with oxygen leaves oxide residues. These residues are particularly visible when the laser-cut tube, after bending.
Laser cutting with nitrogen, on the other hand, is a clean, slag-free cut. Finally, laser cutting with nitrogen allows for a higher processing speed than laser cutting with oxygen.
LASER TUBE WITH THE BENDING AND CALENDERING OF THE TUBE
The use of the iron and steel and Tube Laser before bending the tube or its calendaring allows the elimination of tube processing phases and the consequent additional tooling costs of other machinery.
This is one of our strengths. It is possible to carry out these laser cuts of the tube before bending:
- Drilling of steel tubing with tube laser
- 40x20x2 mm oval steel tube with laser-cut holes before bending
- Laser drilling of the tube
It can be drilled before cold forming. However, this is only possible if the Laser Tube can be tilted over the tube. The Laser Tube in our machine park, for example, tilts up to 45 degrees.
CONCLUSIONS
The Tube Laser is a cutting-edge machine that has revolutionized tube processing techniques, especially bending and calendaring iron and steel pipes. It also allows you to speed up and optimize the production cycle.
This machine has allowed us to laser cut tube bars up to 12 meters long and increase the number of processes before bending the tube, with a consequent reduction in costs and production times.
