ABSTRACT:
A tube shaping apparatus includes a movable frame having an upper portion mounted upon stanchions, an upper and lower tube engaging member mounted upon the frame for holding a tube therebetween, a tube engagement hydraulic cylinder for urging the upper tube engaging member toward and away from the lower tube engaging member, a tube bending die slidably mounted substantially parallel to the upper portion of the frame, and a pair of tube bending hydraulic cylinders for urging the tube bending die along a horizontal plane for bending and shaping a tube held between the upper and lower tube engaging members. The tube bending die is essentially a tongue-like member having an arcuate forward end which effects the bends in the tubes.
