Abstract
An apparatus for bending a metal pipe having a small diameter includes a pipe retaining mechanism and bending units. The pipe retaining mechanism comprises a pair of chucks consisting of a split pattern provided on a support. One of the chucks is fixed and the other is mounted on the distal end of a piston rod of a cylinder device in such a manner that it opposes the one of the chucks. The bending units are provided on the support on two sides of the pipe retaining mechanism in the crosswise direction thereof, and has forming rolls supported to fixtures on the support on two sides of the extension of the axis of the pipe retaining mechanism, as well as press rolls which are pivotal about the forming rolls. The support is fixed to the upper end of a drive shaft rotated in cooperation with a piston rod of a cylinder device on a base, so that the bending apparatus on the support can be pivoted on the plane of the support during bending process.
