  • Patent number: 4899567
    Abstract: A bending die and a method of using the die to bend a pipe or the tube closely adjacent to an end of the tube having an end fitting is described. The bending die has a bending die member with a generally circumferentially extending groove around which the pipe or tube is bent. A clamping die member clamps an end portion of the tube against the bending die member. A clamping jaw member removably attached to the clamping jaw member, has a generally planar clamping face that contacts the end fitting on the pipe or tube. The bending die member defines a notch to accommodate a portion of the end fitting when the tube end is initially clamped to the bending die member. The method of bending the pipe or tube encompasses the steps of cutting the pipe to length, attaching the end fitting to the end of the pipe or tube (such as by welding), inspecting the end fitting-tube joint and subsequently bending the tube.
