  • Patent number: 8511123
    Abstract: A pipe bending machine has a stiff-back which is driven by a pivoting wedge. A linkage applies force from the actuator to the wedge in a direction parallel to a longitudinal axis of the stiff-back. The stiff-back pivots on a first fulcrum and the wedge slides on a bed which pivots on a second fulcrum. The actuator drives the wedge between the stiff-back and the bed to rotate the stiff-back at the first fulcrum and bend the pipe seated in the stiff-back against the pipe bending face of a die. The conversion of the longitudinal force applied to the wedge into a transverse force applied to the stiff-back provides a significant mechanical advantage which varies directionally as the stiff-back rotates about its fulcrum to maintain a constant force on the stiff-back.

  • Patent number: 7584637
    Abstract: A method of bending a metal object, such as a tube, is provided that uses real time, closed-loop feedback of the actual springback of the object in order to modify the applied bending force or preprogrammed bending coordinates so that the final desired bend geometry is achieved. The variability of springback from object to object is thus accounted for and the number of objects that must be scrapped due to incorrect bends (over bend or under bend) is reduced. The method is carried out using an apparatus such as a rotary draw bender with a measuring device operable to measure actual bend coordinates of metal objects bent by the bender. A controller is operatively connected to the bender and the measuring device and is configured to control the bender to bend the metal objects at least partly based on measured bend coordinates provided by the measuring device.
