    Roll Forming Machine Design Technology Introduction

    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.
