摘要： A method is provided for joining tubes. An outer tube and an inner tube are provided. An end of the inner tube is inserted into an end of the outer tube to form an overlapped region of tube wall and form a pressure tight joint between the tubes. The overlapped region of the tubes is heated. The tubes are placed in pair of dies having a die cavity adjacent to the outer tube. Pressure is introduced into the tubes to expand the overlapped region of the tubes outwardly into the die cavity and thereby form an interlocking joint between the overlapped region of the outer tube and the inner tube.

摘要： A tool forms a threaded hole in a hydroformed part while the part remains in a hydroforming die cavity and under pressure. The tool has a hole-piercing end portion adapted on advancement of the tool to pierce and form a hole in the part and an extruding portion adapted on continued tool advancement to extrude an annular extrusion that extends into the tube interior. An adjacent sealing portion of the tool seals the hole during the ongoing advancement and extrusion of the annular extrusion so that hydroforming fluid remains under pressure. A thread-forming portion of the tool forms an internal thread within the annular extrusion upon the continued advancement and rotation of the tool.

摘要： 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.

摘要： A hydrotapping power unit is disclosed that is operable to hold a hydrotapping tool in a home position adjacent a part while the latter is being hydroformed in a die cavity, to then advance the tool to pierce a hole in the hydroformed part while the part remains in the die cavity and under pressure and then continue to advance the tool to inwardly extrude the part about the hole, to then further advance while also rotating the tool at a feed rate equal to the thread pitch of the tool to thereby form a thread in the pierced hole, and finally retract while also rotating the tool but in the reverse direction and at the same feed rate to release the tool from the threaded hole. The power unit for performing these operations includes a linearly moveable shaft for holding the tool, a powered device for rotating the shaft, another powered device connected to the shaft by a lead screw connection having a thread pitch equal to that of the tool, and a third powered device that is adapted to intercept and prevent shock loading on the tool from the piercing operation and thereby on the shaft from reaching the lead screw connection.

The method includes providing a test-piece having an outer surface defined by a length and a substantially round cross-section. The method also includes arranging the pressure die, the clamp die, and the wiper die relative to each other in the tube bender, and arranging the test-piece relative to the pressure die, the clamp die, and the wiper die. The method further includes applying a force by the tube bender to clamp the test-piece, and determining whether the applied force is within a predetermined range of forces. Additionally, the method includes adjusting the arrangement of at least one of the pressure die, the clamp die, and the wiper die to apply a force to the test-piece that is within the predetermined range of forces.
