Tightening system for bent sheet
This final project has been developed by Joseba Lasa and the research
group EMAP from the XIOS Hogeschool Limburg. I came from the University of
the Basque Country in San Sebastian. I have done my thesis for the
The objective of this project has been to design and develop a tightening
system for bent sheet metal parts, because one of the subjects in the research
group EMAP is the dimensional accuracy control of this kind of pieces.
Different kind of bent parts have been proposed. These pieces are being
studied by EMAP in cooperation with sheet metal processing companies. The
bent parts have to be measured accurately and therefore the product has to
be positioned and fixed as good as possible.
When designing a tightening or fixing system we have to be sure that
this system will be as flexible as possible and can tight more than one piece in
the same system. It also has to be as easy as possible to use, to get a good
positioning and to have a short change-over time. And at last, the system has to
be as cheap as possible. It is also interesting to be able to measure pieces in
series to spend less time measuring the pieces.
The following steps have been taken to find the most interesting fixing
system for the different bent plates.
1.- A market study on different tightening methods and tools.
2.- Designing different kind of fixing methods.
3.- Developing the best fixing system
4.- Evaluating the system ( resistance calculations, choosing material,…)
