Sideways Movement of Strip in In-Plane Roll-Bending Process with Conical Rollers

Abstract

As a result of unequal reduction, the sideways movement of the strip at the entry is occurred in in-plane roll-bending process with conical rollers. This will reduce the shape quality of the formed ring. To control the sideways movement, FE simulations with applying unilateral and bilateral guide planes are carried out by employing ABAQUS/Explicit code. The results show that, the strip moves towards the bottom end and scratches with guide plane at the trailing end if applying unilateral guide plane; the sideways movement can be controlled effectively with circularity of 0.993 and maximum deviation ratio of 12.5% for the formed ring if applying bilateral guide planes.
