Sheet metal bending up to 16 m length gas bike alley


We have four press brakes with dimensions 3,500 mm, 6,000 mm 8,000 mm and 16,000 mm. On these press brakes we can use radius dies to bend high-precision inside radii. Radius stamps have to be used if extremely resistant steels, for example HARDOX, are to be bent. These materials are very hard, but tend to tear if the inside radii are too small.

Despite their high toughness, impact resistance und robustness, Dillinger wear plates are have exceptionally good workability. According to the manufacturer, these plates are suitable for cold forming and machining. gas stoichiometry calculator Our machines can be set to sheets and plates with higher strengths, so that any spring back of the material during the bending process can be balanced out.

The sheet must be inserted in the machine so that the material only sits on the two upper edges of the die. The preprogrammed insertion depth (stroke depth) of the punch is CNC controlled; the upper tool (punch) presses the sheet into the die and in doing so bends the required angle. However, the lowering operation ends before the sheet touches the die. The main advantage of air bending is the flexibility of bending different angles without having to change the tool (die). This is also a reason why air bending is used so frequently. Coining

Bending film is easy to handle. It can be changed quickly and easily. As the film prevents direct contact between the tool and the material to be bent, there is no soiling or contamination of the bent parts. It is therefore not necessary to rework or finish the metal sheets. electric utility companies charge customers for This naturally increases the quality of the product. What is the minimum bending radius?

At Rime the forming is carried out using four modern CNC press brakes with 4, 6, 8 and 16 m dimensions. These presses are CNC controlled and make facilitate the bending operation immensely. Our ability to simulate bending processes helps us to avoid trial bending and therefore to save time and material. Yet machines can’t do all our work for us. In principle, the bending is done by inserting the punch in the die.

The metal sheet is inserted between the two tools, and when the punch is lowered the sheet is pressed into the die and in this way the required angle is bent. electricity receiver Yet this bending process conceals several details, which always have to be taken into account for optimum bending. All metals do not behave the same when they are exposed to large forces. Minimum bending radius

The minimum bending radius is the smallest possible radius, with which a metal sheet panel can be bent without damaging the material. electric zap sound effect free This value depends on the material and sheet thickness. There is a rule of thumb for steel sheets, which says that the minimum bending radius must at least be equal to the value of the sheet thickness. For aluminium the minimum bending radius is equal to the value of twice the sheet thickness. If the bending radius is less than this value, the sheet can tear at the edges, or material can spall from the surface. Spring back

Metal sheet formats 8 to 16 metres in size Larger, faster, further… – Striving for progress, moving one’s own limits and overcoming technical limits are anchored deep in human nature. And so each year new records are broken. In 2010, the highest building in the world to date was completed in the United Arab Emirates. v gas station From the ground to the tip of the roof mast the “Burj Dubai” is a lofty 830 metres high. There are vehicles that drive faster than sound in the salt desert of Arizona and bridges which nor only span wide rivers but also whole straits.

In the machining of metal sheets the trend is towards ever-larger workpieces. There are several advantages in being able to bend sheets with a length of over 8 m. A few years ago it was not possible to machine large parts. For example, if a 16 m long bent part was required; such workpieces had to be welded together from several smaller parts.

Despite modern welding procedures, welds are still a weakpoint. The effect of heat during welding not only melts the material. It also changes its crystalline structure slightly, which then weakens load-bearing capacity and increases the rust susceptibility of the large part made. Making welds is also time-consuming and material-intensive, for example, because welded bridge girders have to be welded using a gas shield and then checked using X-ray testing.

Increasingly large-sized parts are being produced in order to reduce this expense. Machines that are able of machining such parts grow in line with the ever larger sheet metal parts. In Europe there has been a strong demand for large parts in recent years. gas house eggs International transport of long metal sheets or plates is expensive, so that import from Asian countries is only worthwhile for small parts. Bending thick plates and long sheets

We now follow these new requirements and since 1 December 2011 we have been able to bend very long sheet metal parts. Yet this is only one facet of our new possibilities. Often it is not only a matter of bending large parts with a specific length – the ability to bend large sheet thicknesses or rather metal plates is also very much in demand. To achieve this we have a modern press brake with a total pressing force of 25,000 kN. This means that the machine is practically able to bend 30 mm thick steel plate along its whole length.

This machine even manages to bend plates that are 70 mm thick with a bending length of 2,000 mm. Our existing “XL” offer is becoming ”XXL” and we can offer you sheet metal and plate parts, whose length are only just still transportable with a truck. With such workpieces we enable the construction and development of larger and more stable structures and follow our human goals to erect ever larger and better structures.
