Abstract (en)
Computer assisted machine for the cold bending operations, by controlled drawing on the three spatial dimensions, of metallic or composite profiles, in elongated forms, such as the profiles used in the automobile industry. The machine is characterised by the fact that all driving movements, necessary to bend the profile into the desired geometric configuration, are performed by the machine itself, while the tools are made up of only the parts that come in contact with the profile being shaped, during the bending operation. Additionally, the machine is capable of controlling the bending of the materials in a single production lot, or in different lots with varying mechanical characteristics, but otherwise subjected to acceptance specifications, in order to obtain, in all instances, components that respect specified tolerances. <IMAGE>
