Abstract: A disclosed device and method are useful for monitoring a tube bending process. An example sensor detects a force associated with moving a mandrel in tubing during at least a portion of a tube bending process. The detected force is used to determine a quality of the tube bending process. For example, a detected pulling force provides an indication of whether a bent portion of a tube is within an acceptable range of a desired configuration. The detected pulling force is also useful to provide an indication of whether a condition of a mandrel or a machine used during the process is as expected.

Abstract: A device for slipping a tube on the mandrel of a bending machine includes a support upon which a pair of slides are slidably mounted for movement in a direction parallel to the axis of the mandrel. A double arm lever is pivotally mounted to each slide, about axes parallel to the axis of the mandrel and a cylinder is mounted between the first ends of the levers. Gripping jaws are removably mounted to holders rotatably connected to the other ends of the levers, the gripping jaws being adapted to clamp a tube to be bent therebetween on opposite sides of the mandrel. A further cylinder is provided for moving the slides in a direction parallel to the axis of the mandrel.

Abstract: A tube bending machine having the capability of releasing the tube from the carriage for longitudinal movement during bend formation, while maintaining a plane of bend reference. The end of the tube is connected with a rod extending through the carriage collet. The rod has a non-round cross-section and extends through a mating adapter on the carriage which permits relative longitudinal movement while preventing relative rotation between them.

Abstract: A discharging furnace and a filling furnace are disposed in three dimensions in the upper and lower positions of a filling and discharging furnace. A reservoir is provided in an inclined surface protruding toward the lower filling furnace. The reservoir includes a valve operatively connected thereto. A hot blast heated by a duct heater through a duct is mainly fed into the discharging furnace for further heating, while a remaining small portion of the hot blast is fed into the filling furnace for keeping the filling furnace warm. Inside the discharging furnace, a filling material filled in a bent workpiece is molten and discharged into the reservoir and when the valve is opened, the gathered filling material is filled into the inside of the workpiece which is carried by a filling carrier. The filling carrier is divided into three portions of a filling pallet, a carrier body and a sealing pallet, wherein the filling pallet is provided with a nozzle and the sealing pallet is provided with a seal member. When the sealing pallet is moved upward, a slide deck is also moved up in a condition which the seal member is engaging with the lower end portion of the tubular workpiece, so that the tubular workpiece can engage at its top end portion with the nozzle. The filling material gathered within the filling pallet is then filled through the nozzle into the workpiece. In case the specification of the workpiece is changed, the nozzle and the seal member are replaced.
