the basics of roll form tooling design

Mar 27, 2003 · Before you can design the rolls, you must determine the proper number of passes and the rolling mill. After calculating the estimated strip width, you can develop the flower by using the arc and straight lengths. On a typical C channel, the return leg (bend No. 2) is the first forming to be done (see Figure 2). Some designers prefer to form this leg to about 70 to 80 degrees in three passes, depending

W or Reverse Bend Style Rolls. Reverse bending is a variation of edge forming. It is a technique as old as metal forming itself. It’s as simple as lifting or reorienting a piece of metal so that a hammer blow strikes it more advantageously. On a tube mill the hammer is the first pass top breakdown roll. Effectively the first pass rolls lift

features of the cold-rolling of tubes on tandem mills with

Nov 29, 2013 · Aspects of rolling on tandem four-high cold-rolling tube mills are studied. The article examines how the gear ratio of the diagonal transmission of the stand is related to the axial force on the semifinished product and loss of stability by the tube. An improved method is developed for designing the rolls so that the deformation process is divided between a pair of breakdown rolls and a pair
