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.
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 50,000-ton press was the largest machine in the world at the time, 10 stories high and with foundations extending 100 ft (30 m) into bedrock. In 1983, the American Society of Mechanical Engineers designated the 50,000-ton forging press in North Grafton as a National Historic Mechanical Engineering Landmark. [6]
Joseph Bramah patented the hydraulic press in 1795. [1] While working at Bramah's shop, Henry Maudslay suggested a cup leather packing. [2] [clarification needed] Because it produced superior results, the hydraulic press eventually displaced the steam hammer for metal forging.
