摘要:
An apparatus and method configured for manufacturing an aircraft part from formable material. The apparatus may include one or more rigid forming components onto which the formable material is placed and between which non-flange portions of the formable material may be compressed, and at least one inflatable component that, when expanded by inflation, presses flange portions of the formable material against at least one of the rigid forming components. The inflation component(s) may be arranged in any configuration for forming the formable material into C-shaped channels, single L-shaped channels, or opposing Z-shaped channels. Once pressed between the rigid forming components and/or the inflated inflatable components, the formable material may be heated for forming according to the particular formable material used.

A titanium alloy metal sheet is provided and heated to a superplastic forming temperature. A die has a plurality of housing forming areas each corresponding to one of the medical device housing portions. The heated titanium alloy metal sheet is forced onto the die and over each one of the plurality of housing forming areas, thereby superplastically forming a workpiece comprising a plurality of integrally formed implantable medical device housing portions.

A hydro-formed body side rail is assembled by a bracket to a front header. The front header is an extruded cross-car structural support that is joined to the body side rail by a framed joint. A gap is defined between the body side outer panel and the hydro-formed side rail relative to a lateral end of a front header. Side impact test loads are applied initially to the body side rail and compress the bracket. Compression of the bracket closes the gap and the impact loads are applied to the cross-car structural support.

A production method uses ultrasonic forming but does not leave a bonding face exposed to the exterior in a final product. The production method of a leading edge member of a fan blade comprises the steps of causing superplastic forming by using a combination of a first mold having a flow path for gas and a second mold having a female mold to pressurize a plate member with the gas through the flow path to fit the plate member onto the female mold; bonding a backing with the plate member processed with the superplastic forming; and cutting out a periphery of the plate member to obtain a product shape.

An apparatus and method are provided for the simultaneous forming of a plurality of shaped articles from plural sheet metal blanks. First and second sheet metal blanks are arranged between upper and lower forming dies, and a nozzle body having a generally diamond-shaped cross-sectional profile, transverse to an insertion direction, is inserted between the sheet metal blanks. When the forming tool is closed, upper and lower sealing surfaces of the nozzle body press the first and second sheet metal blanks, respectively, against sealing beads that are arranged one each within peripheral areas of the upper and lower forming dies. Opposite side edges of the nozzle body converge one toward the other so as to facilitate forming a seal along each of the side edges of the nozzle body. A pressurized fluid is introduced via the nozzle body for forming the sheet metal blanks within a die cavity.

An end band and method of forming an end band for a rotor. The end band includes a hollow cylindrical band, wherein at least a portion of the band has a grain flow in a direction parallel to the hoop stress of the band. The end band also includes at least a portion having a grain flow in a direction perpendicular to the hoop stress of the band.

A method for forming a metal article includes: heating a mold to a working temperature ranging from 350° C. to 550° C., the mold having a forming surface with a predetermined pattern; disposing a metal sheet in the mold that has been heated, the metal sheet being made from one of aluminum alloy and magnesium alloy and having a temperature not higher than 100° C.; and forming the metal sheet by applying a fluid-pressure of not less than 10 kg/cm2 into the mold to press the metal sheet against the predetermined pattern.
摘要:
A system for producing composite or bonded metal components including: first and second pressure chambers, each pressure chamber having an elastically deformable chamber wall; means for circulating fluid at an elevated temperature and pressure through each said pressure chamber; and at least one mould assembly including at least one separate mould section providing a mould cavity within which a composite or bonded metal lay-up can be located; wherein when the system is in use, the pressure chambers are held together with the elastically deformable chamber walls located in opposing relation, the at least one mould assembly containing a said lay- up being accommodated between the chamber walls while fluid at elevated temperature and pressure is circulated through each pressure chamber such that the lay-up can be compressed and cured or formed.
