    摘要： A system for hydroforming a workpiece containing fluid at elevated pressure includes a die in which the workpiece is formed, a source of control pressure, a tank at low pressure, and a valve that includes a displaceable control element that alternately moves between an open state and a closed state, opening and closing, respectively, a passage that hydraulically connects the fluid in the workpiece and the tank in response to the relative magnitudes of a first force applied to the control element by the control pressure source and a second force applied to the control element by pressure of the fluid in the workpiece acting on the control element in opposition to the first force.

    摘要： The invention provides a hydroforming apparatus for forming a length of tube. A hydroforming press includes an upper platen and a lower plate. A first die set is provided for forming a first lengthwise portion of the tube and a second die set provided adjacent the first die set which forms a second lengthwise portion of the tube. A first pivot acts between a first and second upper die so that the second upper die can be pivotally adjusted on the upper platen relative to the first upper die. A second pivot acts between a first and second lower die so that the second lower die can be pivotally adjusted on the lower platen relative to the first lower die. A die insert is provided having an upper die insert and a lower die insert that define upper and lower insert cavities that connect together the first and second cavity portions of the upper die set and the lower die set. This die insert is removably mounted as needed to accommodate the pivotal adjustment between the first and second die sets.

    摘要： A hydroform seal assembly includes a seal housing and an annular nozzle carried by the seal housing and sized to insert into a tube end. A first actuator moves the seal housing to insert the nozzle. A plurality of jaws are carried by the seal housing and are movable radially inward into clamping engagement with the tube to clamp the tube onto the annular nozzle. A cam bushing is movably mounted within the seal housing, surrounds the jaws, and has cam surfaces complimentary with cam surfaces provided on the jaws so that movement of the cam bushing relative the jaws will cam the jaws radially inward. A backup cam is movable within the seal housing. The cam bushing and backup cam have complimentary cam surfaces by which movement of the backup cam will forcibly move the cam bushing relative the seal housing. A second actuator moves the backup cam.
