ROLLING DEVICE AND THE METHOD THEREOF

摘要

A rolling device for three-dimensional curved surface forming or thin sheet rolling of a sheet metal, comprising a forming roll (1), a supporting mechanism, an adjusting mechanism and a driving mechanism. The forming roll (1) comprises an upper forming roll (1a) and a lower forming roll (1b); the supporting mechanism is a multi-point supporting mechanism (2a) or an overall supporting mechanism (2b) for supporting the forming roll; the adjusting mechanism is a multi-point shape adjusting mechanism (3) and/or an overall displacing mechanism for adjusting the shape and/or relative height of the forming roll (1); and the driving mechanism applies a torque to one or two ends of the upper forming roll (1a) and/or the lower forming roll (1b). The present invention also provides a method for sheet rolling by using the rolling device. The rolling device and rolling method can achieve three-dimensional curved surface rolling or thin sheet rolling of a sheet metal simply, quickly and at a low cost.
