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.
