E-grāmata: Roll Forming Handbook

Although he notes a number of exceptions, Halmos (president, Delta Engineering Inc., Canada) defines roll forming thusly: "To form sheet metal strip along straight, longitudinal, parallel bend lines with multiple pairs of contoured rolls without changing the thickness of the material at room temperature." In this handbook on roll forming he presents advice guidance and advice on the process from basic questions of operation and mill design to future technologies. The specific topics discussed are roll forming mill; presses and die accelerators; secondary options in the roll forming line; roll design; materials; lubrication; coil processing, material handling, and plant layout; designing products for roll forming; equipment installation, roll setup, maintenance, and troubleshooting; behavior of metal strip during roll forming; acquiring roll forming lines, education, and training; safety; increasing efficiency of roll forming lines and case studies; and unusual, new, and future roll forming technologies. This is part of a series formerly published under the Marcel Dekker imprint. Annotation ©2006 Book News, Inc., Portland, OR (booknews.com)

Roll forming is one of the most widely used processes in the world for forming metals. Most of the existing knowledge resides in various journal articles or in the minds of those who have learned from experience. Providing a vehicle to systematically collect and share this important knowledge, the Roll Forming Handbook presents the first comprehensive, dedicated treatment to all facets of roll forming, supplying references to more in-depth information to fill in the gaps.

This book spans from conception of the roll forming operation, purchasing and specifying equipment, and roll design to maintenance, troubleshooting, safety, and operator training. Detailed discussions reveal how material, equipment, tooling, and operator factors affect overall efficiency and product quality. Expert contributors share insights based on many years of hard-won experience, including effects of secondary operations such as punching, embossing, curving and cutting in the line; designing products for efficient roll forming; mechanical properties of metals, lubrication and the influence of coatings on roll design and forming; and mathematical simulations of various deformations that occur during processing to determine their causes and find a solution.

Outlining a practical approach to select, set up, and operate roll forming lines, the Roll Forming Handbook combines scientific background and practical know-how that enables you to set up cost-effective and high-quality roll forming lines with confidence.
