Abstract: The present invention relates to a tube bending apparatus which has a portable size and is easy to handle, with less cost of bending. The bending apparatus comprises a base plate having an elongated frame mounted on it. The frame includes a top support plate and a bottom support plate parallel to each other, a square support tube and four support bars. A pair of lateral rollers are mounted on each side of the two support plates of the frame and a power means, such as a hydraulic or mechanical ram, is mounted to the support tube to provide a reciprocating movement. A mandrel is engaged to one end of the ram and also to a bending die member which has a semi-circular configuration on its front face and grooves extending on the semi-circular face for relieving stress during the bending operation. The ram is loaded with one or two springs for the convenience of changing and accommodating the bending die members when reloading different sizes of tubing.
