  • Flexible forming device for forming three-dimensional shaped workpieces
    Patent number: 8210014
    Abstract: A flexible forming device for forming three-dimensional shaped workpieces, comprising a frame, at least two working rollers, one or more working roller driving mechanisms and one or more adjusting mechanisms, wherein the working rollers, the one or more working roller driving mechanisms and the one or more adjusting mechanisms are installed on the frame respectively. At least one of the working rollers is a flexible working roller, which is bendable and adjustable. The forming device need not use mold and can realize the continuous formation of a three-dimensional curved surface of a plate-shaped workpiece, and the gradual formation of a tube-shaped or bar-shaped three-dimensional shaped workpiece. The forming device can save manpower, material and time.
