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 is provided for setting up a tube bender having a bend die, a clamp die, a pressure die and a wiper die. 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.

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 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 hydroforming seal and method includes a nozzle having both a radially expandable O-ring seal and a conical tapered surface for separately sealing with the bore of the tube. The O-ring seal is expanded to seal the tube and pressurized fluid is added sufficient to support the interior of the tube while the dies are closed so that the tube is thereby bent and forced into the die cavity without collapse or injury to the tube. The O-ring seal is then contracted to a non-sealing position and the conical tapered surface provides metal-to-metal sealing while the higher hydroforming pressure is applied to expand the tube. The nozzle also has a radial shoulder that engages the end face of the tube so that advance of the nozzle feeds the tube into the die.
