The basics of roll form tooling design - The FABRICATOR
Mar 27, 2003· Design the Layout and Roll Tooling After completing the flower, you need to choose drive diameters and check for maximum flange roll sizes and possible interference with the rolling mill During the design phase, you'll need to consider increasing the pitch diameters of the rolls from pass to pass (also called step-up)
Tube roll design is an organized process culminating in the production of a roll formed welded metal tube First consideration is the products’ specific characteristics of size, shape and physical properti The next consideration is the forming and welding machinery available to the producer
Tube and Pipe Roll Tooling Design If you want to produce the best and most cost effective tube and pipe, you need the best tooling design Most tube and pipe producing companies know that if the roll tooling design is not correct, you will experience increased scrap due to marking, difficult setups, welding and other formation problems
And additionally, company-specific calculation methods can be included easily Nevertheless a critical remark: Decisive for a correct definition of strip width is a precise setup of roller tools which is guaranteed by the under design of the flower pattern mentioned calibration methods for profile unfolding
