GENERAL CONCEPTS of cold roll former line processing:Roll-
forming is a process in which the shape of a metal panel is
developed by gradually bending the metal through a series of
roll forming machine, or passes. Each stand must generate
the appropriate amount of deformation for which it was
designed. In general, the level o deformation at each stand
is not constant due to adjustments for spring back and the
preservation of dimension. Since the tooling is designed to
control the outside dimensions o a panel, roll formers are
usually designed to overwork the metal in specific stands.
Problems in the forming system or tooling design may exist
if materials have to be overworked in the stands/tooling
other than those designed for overwork. Therefore, when
roll-forming problems occur, it is important to examine each
stage of the process and not merely the stand at which the
problem initially appears.
Two basic types of roll-forming systems are utilized: a
precut line and a post cut line. A precut line shears the
incoming material to a specific length prior to roll-
forming. During post cut line operation, the roll formed
panel runs continuously and is sheared to the required
length after roll-forming.
material:One of the principal parameters that define the
success of a roll-forming operation is the nature of the
material. In order to design the optimal process, the
tooling designer should be provided material information to
be used prior to the tooling designing. This includes
material mechanical property ranges, gauge tolerances and
shape tolerances. In addition, different metallic coatings
(hot-dip galvanized or GALVALUME1 Coated Sheet Steel),
organic coatings or paint will result in differences in
performance even with the same set of tooling due to their
different frictional characteristics.
