Abstract

The invention discloses a digital flexible forming device and method of a large-size ring unit. The device comprises a power and transmission mechanism, a flexible roller system, a flexible clampingsystem and a reconfigurable die system. The power and transmission mechanism is used for adjusting the position of the flexible roller system and driving the flexible roller system to rotate for forming. The flexible roller system is used for roll-bending forming of any large-size three-dimensional ring part. The flexible clamping system is used for clamping a to-be-formed plate material. The reconfigurable die system is used for rapidly producing a flexible digital die. By means of the device, the organic integrating of flexible clamping, rapid shape adjusting and incremental press-rolling isrealized, and the rapid and precise forming of ring shell type parts of different shapes and sizes can be realized. In addition, the invention further provides a method for forming a target part through multiple times of incremental press-rolling through the four steps of shape adjusting of a flexible roller and a multi-point die, clamping of the plate material, downward pressing of a roller androll-bending forming, and an integrated rapid and flexible forming new method is provided for the ring shell type parts.
