ABSTRACT:
A pipe bender 100 comprises a base 111, a former 132 on the base and having a former surface extending angularly at a fixed radius about a bending axis 114. The former surface is provided to engage a length of pipe 134 to be bent to conform to at least a portion of the length of the former surface. A bending arm 113 is pivotally mounted on the base 111 for pivoting movement about the axis 114. A bending assembly 115 is mounted on the arm 113 and includes two deforming rollers 122, 123 rotatably mounted for movement about an axis which is parallel to the bending axis 114 and spaced radially outwardly of the bending surface. The rollers 122, 123 are adapted to engage the length of pipe 134 to cause bending thereof as it is moved angularly about the axis 114. The rollers 122, 123 are substantially co-extensive, with one of the rollers being positioned radially with respect to the bending axis 114 so that in use the one roller is positioned at approximately the bending point of the pipe, the other roller being spaced angularly forward of the one roller and radially further from the bending axis 114 than one roller. A hydraulic ram 126 is provided to cause angular movement of the arm 113 about axis 114 to thereby move the roller and deform the pipe.
