Forming where the workpiece is clamped onto a fixed bending template after which a rotating template, press the tube free end along bending template contour. Beskrivning The process The workpiece, in this case a tube pressed by a pressure bar [1] against the fixed form block [2]. The wipe shoe [3] is pressed against and drawn along the radius of the block so as to bend the tube along its contour by plastic deformation. Sometimes a bending core [4] is used but it’s usually done without it, thus giving an oval cross section in the bent area. Compression bending of Tubes Process films Advantages and disadvantages In comparison with alternative methods Cheap method Simple tools The tube can get deformed Limited to certain pipe sizes
