| M3 - COPRA Professional Tube Mill Roll Design Center | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
 The COPRA Professional Tube Mill Roll Design Center is the advanced and worldwide leading software package for tube mill roll design. It includes features as...  Project manager Data base archiving Machine data setup Setup for forming methods (circular, 2-radius, W-forming, 4-radius, oval
welding shape or others...) Forming strategy setup Setup of forming parameters Roll design setup Automatic flower design Automatic roll design Parametric roll modification
COPRA does not only create the flower, but all the tooling as well
Not just some of the required parameters (additions) are considered by the
program. COPRA stores all the parameters required for a proper tube mill roll
setup and presents them in user-friendly dialoque boxes (with self-explaining
figures) to the operator.
COPRA Professional Tube Mill Roll Design Center
meets the requirements of major tube mill manufacturers in more than 50 countries worldwide!
The International Tube Association has honored data M's
achievements in this regards with the "president's trophy award".
COPRA allows to define calibration method as well as forming strategies
according to your requirements (e.g. one radius, two radii up to up to 4 radii method or more or oval shapes), which
can be run automatically.
COPRA furthermore allows for automatic and parametric design of
roller tools.
Currently, optimized forming (down-hill forming) can exclusively be
calculated by COPRA. COPRA allows to predict
and optimized forming sequence. software

COPRA®
Professional Tube Mill Roll Design Center is tailored to the
needs of making round or rectangular tubes or pipes. Common
types of tube welding lines and respective types of forming and
calibration passes are already stored in COPRA's data base and
can easily be extended, copied or modified according to your own
needs.
The calculation of the roll forming steps is done according to
predefined strategies and can be adapted to your requirements.
COPRA's design functions are fully parametric. User friendly
dialogue boxes are allowing an easy access to the most effective
functionality. Easy definition of tube mill layout

COPRA
also includes a software program for the calculation of the optimum down-hill forming
curve.
It has been shown that the widespread opinion that a constant gravity point
was the optimum forming method is wrong.
A special purpose optimization program provides the possibility to minimize
material strain. With this option the optimum forming curves for the individual passes
(including cage forming) can be determined.
Leading roll forming and tubing companies have been using this software
all over the world

M4 - COPRA® Professional Design Module for Shaped Tubes |
 COPRA Professional Design
Module for Shaped Tubes allows you to calculate calibrating passes from round
tubes to special shapes.
COPRA Professional Design Module for Shaped Tubes allows for a quick
and accurate design of calibration forming steps
Calibrating to shaped tubes is usually (but not necessarily) starting from a
round tube.
The individual calibrating steps are calculated and optimized on
the computer as a basis for the following roll design.
"The user can hear the
improvement you get from roll sets designed by COPRA Professional Design Module for Shaped
Tubes" says Mr. Lahni, production manager at Mannstaedt Works, Cologne/ Germany. The
noise generated by the calibration passes was reduced drastically due to the smother
forming process achieved by COPRA design.
Both, calibrating to shaped
tubes as well as drawing a tube through a drawing ring, is starting from a round tube.
Left picture shows an example how the different calibrating passes of a tube mill can be
generated by a computer program. The individual calibrating steps are calculated and
optimized on the computer as a basis for the following roll design. The photograph on the
picture below also shows the corresponding practical example.
The shown example was calculated by COPRA and produced on respective tube
mill.
The forming passes were optimized by COPRA Professional Design Module for Shaped
Tubes. |

How does COPRA Professional Design Module for Shaped
Tubes work?
The design of the
profile's cross section which has to be produced is easily done via CAD functions or
COPRA's tailored functionality.
In order to perform the (not trivial) calculation from the final
cross section back to the cross section the user wants to start from
(usually the round one) it may be chosen between two mathematical
statements: Calculation of respective angle values or the so-called topographical method. The drawing left shows an example of the "angle-method". A correct distribution of compression values allows the user to avoid "undercuts" which might lead otherwise to difficulties during the production. Compression in single forming passes may can also be set to a resulting total profile compression value (over the whole calibration from round to special shape). 
Exact setting of
forming strategy:In case of uniform forming, the arc angles of the shaping steps are exactly within the angles of the respective entities in the two adjacent passes. Distribution of angle modification can be set in percent. The user has access to a number of optimization settings -
concerning iteration, gap widths, angle adjustments and computing time. COPRA Professional Design Module for Shaped Tubes is being
used by major tubemakers -
