Pipe or tube bending device has a hollow bolt, center spike, bending flange with lower and upper parts supported on the bolt and spike respectively and a control bush coupled to a bending mechanical drive

摘要

Bending device has a hollow bolt with a center spike that can be adjusted in a linear direction. A control bush is arranged around the hollow bolt so that it can be rotated about the bolt central axis. The device also has a bending flange (13) that is divided into two parts. A lower part (131) is first supported on the hollow bolt (11), while an upper part (130) is supported on the center spike (12). The control bush (14) is coupled to the bending mechanical drive (2).
