What is iron bending?
Bending is a forming operation in which a sheet metal, in this case made of iron, is subjected to bending stress: that is, a straight sheet is turned into a curved one. Iron bending plastically deforms the iron sheet, but it does not change its thickness.
The kinds of iron bending performed by Minifaber
As the second most popular metal after aluminum, iron finds application in several different sectors. To cover all those needs, we perform various iron bending processes.
If a V-shaped die and punch are used, you obtain the so-called V-bending. This kind of iron bending allows reaching corners until 90 degrees and includes three subgroups: air bending, coining and bottoming.
When iron bending involves the use of cylinder molds, we obtain the so-called U-bending. This process is most used to fabricate beams, channels and various kinds of frames.
Iron rotary bending
In this kind of iron bending, a bender vurve the iron surface through a cylinder or rotary die. This technique is most used for complicated bends in the machine and parts industry.
Our machine fleet for iron bending
7 bending machines ranging from 30 to 180 tonnes: this is what our machine fleet for iron bending is composed of.
All the machines are CNC technologically advanced and can bend either large quantities or single pieces with the utmost precision.
Depending on the product you need to obtain, we know which one to use for iron bending.
Overcoming springback problems: things to take into account
Iron bending – and also other kinds of metal bending – must always be performed by professionals because there are a series of things to evaluate before starting, that is:
- the properties of the metal
- the processing temperature
- the stress due to previous processes
- the kind of the edges to obtain
- the length and the thickness of the workpiece
A major problem in iron bending is also represented by spingback. After the load is lifted, metals always naturally spring back a bit, so they must be bent beyond the required angle in order to obtain the desired shape.
