The Wyman-Gordon 50,000-ton forging press. The Heavy Press Program was a Cold War-era program of the United States Air Force to build the largest forging presses and extrusion presses in the world. These machines greatly enhanced the US defense industry's capacity to forge large complex components out of light alloys, such as magnesium and ...
The press, circa 1985. The Wyman-Gordon 50,000-ton forging press is a forging press located at the Wyman-Gordon Grafton Plant that was built as part of the Heavy Press Program by the United States Air Force. It was manufactured by Loewy Hydropress of Pittsburgh, Pennsylvania and began operation in October, 1955. [1]
The hydraulic press depends on Pascal's principle.The pressure throughout a closed system is constant. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force.
The Alcoa 50,000 ton forging press is a heavy press operated at Howmet Aerospace's Cleveland Operations. It was built as part of the Heavy Press Program by the United States Air Force . It was manufactured by Mesta Machinery of West Homestead, Pennsylvania , and began operation on May 5, 1955.
A forging press, often just called a press, is used for press forging. [21] There are two main types: mechanical and hydraulic presses. Mechanical presses function by using cams, cranks or toggles to produce a preset (a predetermined force at a certain location in the stroke) and reproducible stroke.
Forging a nail. Valašské muzeum v přírodě, Czech Republic. Forging is one of the oldest known metalworking processes. [1] Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could ...
In 80-90s hydro-mechanical and hydraulic radial forging machines appeared that do not have the disadvantages inherent to mechanical RFM. [4] [5] Nevertheless, radial forging machines are very specific and very expensive equipment in comparison with multipurpose forging presses. The application of such machines at enterprises with a wide range ...
The operator of a forming press is known as a press-tool setter, often shortened to tool-setter. Presses can be classified according to their mechanism: hydraulic, mechanical, pneumatic; their function: forging presses, stamping presses, press brakes, punch press, etc. their structure, e.g. Knuckle-joint press, screw press, Expeller press
