Roll Forming Machine Design Technology Introduction

Product Description:
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.
