Profile bending machine
When you
should need at and can replace standard tube bending? Profile bending machine or section bender or
“3 rolls tube bending machine” is the machine to use principle of driven
rollers and the force of the middle roller to form the bend. But we will not
talk about the technology so we will talk when you can use it…
Main
restrictions of the possibilities are small radius bends. So to form radius
with 3 or better 5 diameters of tube is not the problem but with tight radiuses
– forget about this type of the machinery. So it is not the machine for
industrial pipelines or connections but the good machine for design and
architecture, spirals and some outdoor products, greenhouses tubes.
The
investments could be very low for small machinery. Machines are very simple,
with mass market and a lot of manufacturers it the world so if you do not have
really special product (for example to make the cabin profile with different
radiuses in one cycle) you can easily find the machine with your budget and
necessities. Do not ask a lot of this type of the machinery but know that real
CNC versions could be very interesting to change radius. Some German and Swiss
companies offer the precise versions – with more hard price but to make more
precise parts for the field, for example for boat railing where pair of tubes
needs to be really mirrored without any difference.
Every time
note that profile bending machines has the specialization for the profiles. It
is very complicated to deal with bar or beam with tube bending machine so
profile bender is only choice for this kind of applications. The machine
possibilities are calculated for the bending of solids and not the hollow
pieces.
