Abstract

The invention relates to a tube bending machine and a clamping mechanism thereof. The tube bending machine comprises: a heading mechanism installed on a bed piece along a metal tube transportation path, two boosting mechanisms, rotary structures and two clamping mechanisms, wherein when the metal tube is bent, the heading mechanism holds the metal tube and provides an axial driving force. One of the two clamping mechanisms protrudes under the metal pipe and clamps the metal tube from the side, and one of the two boosting mechanisms pushes against the metal tube. The clamping mechanism comprises: a side snap gauge, an elastic support rod and a boosting part. One side of the side snap gauge is hinged on the end part of the elastic support rod, and the other side thereof pushes against the boosting part. When the boosting part drives the side snap gauge and the elastic support rod to move toward the metal tube and the elastic support rod is blocked, the elastic support rod is elastically deformed along the axial direction, while the side snap gauge revolves around the end part of the elastic support rod under the impetus of the boosting part.
