Schuler and its affiliate Farina demonstrated what the companies say is the world’s largest mechanical forging line to an international group of 60 forging experts. A live video stream transmitted from the production site in Suello, Italy, highlighted the features of the 16,000-ton press, which has a stroke of 600 mm, in action. The press will be delivered to Germany’s thyssenkrupp Gerlach. Due to its Scotch Yoke design, the press has a total height of 14 meters – making it much smaller than conventional presses. This enables high off-center loads and a high number of strokes. From the outside, the GLF-type machine looks like a conventional press, including the flywheel, clutch and crown gear. However, the Scotch Yoke directly works in the slide, which is the reason for the compact design.
Anhui Anhuang Machinery Co. Ltd. placed an order with SMS group for a fully automatic closed-die forging line for pistons. The 2,500-ton line consists of a fully automatic closed-die forging press and an induction heating system from SMS Elotherm for heating the forging blanks. Anhui Anhuang will be one of the first automotive suppliers in China that is capable of manufacturing pistons for cars and trucks in a fully automated process. Commissioning is scheduled for the second quarter of 2022.
Germany’s SMS group acquired Italian companies Hydromec S.R.L. and OMAV S.p.A. to further expand its product range in the forging-press and extrusion-plant markets. Hydromec manufactures forging presses and ring-rolling mills, and OMAV supplies aluminum extrusion lines. With its extended product portfolio, SMS group is now able to supply complete extrusion lines and forging plants with all upstream and downstream equipment and process technology from a single source.
Germany’s Kaiser Aluminium-Umformtechnik GmbH, a manufacturer of forged-aluminum components for small- and medium-sized products, successfully started up its first Schuler servo screw press. The system will be primarily used to produce complex chassis components for the automotive industry. The investment further expands Kaiser Aluminium-Umformtechnik’s market position as a competent partner for forged parts and components in the aluminum sector.
SMS group put a 31.5/34-MN open-die forging press into operation at Gustav Grimm Edelstahlwerk (GGE), a forge based in Remscheid, Germany. GGE specializes in the manufacture of high-alloy forgings. Because of the built-in hydraulic and control systems, GGE’s new high-speed forging press achieves time savings of about 10% compared to the old press. For the first time, SMS group has installed an additively manufactured machine component in an open-die forging press. The 3D-printed hydraulic manifold block is lighter, more compact and has a flow-optimized design. Designed by SMS group and made of an aluminum alloy, it weighs just one-tenth of the conventional steel component. The manifold block is used to distribute hydraulic oil for operating and venting the cylinders.
China’s AVIC Shaanxi Hongyuan Aviation Forging Co. Ltd. put what it says is the world's largest clutch-operated screw press into operation at its site in Xi’an, Shaanxi Province. The SPKA-type clutch-operated screw press, which was supplied by SMS group, has a screw diameter of 1,330 millimeters (52 inches), a blow force of 365 MN, a gross power of 27,000 kJ and a weight of 2,900 tons. It offers flexibility when it comes to optimizing the forging process and requires far less stroke to achieve the preset ram speed than a conventional slipping-wheel screw press. This type of press is particularly suited for high-energy forging typically used for turbine blades or structural aircraft components.
Thyssenkrupp will build an advanced forging line at its Homburg site in Germany’s Saarland region. The company will invest approximately $90 million in a new 12,000-square-meter facility to produce forged front axles for trucks. The centerpiece of the highly automated and digitized forging line will be a 16,000-ton forging press measuring 32.8 feet (10 meters) high and weighing 1,700 tons. According to thyssenkrupp, the press will produce 360,000 forged components per year and will not be restricted to one product. In addition to front axle systems, the line will be able to produce crankshafts and other forged parts as required.
ParkOhio completed the previously announced acquisition of Erie Press Systems (formally EFCO Inc.) of Erie, Pa. Erie Press manufactures advanced forging presses, hydraulic and mechanical presses, and metal stretch-forming and carbon extrusion machines for end markets including aerospace and defense, primary metals and high-speed rail.
SMS group received the final acceptance certificate from Japan’s Hitachi Metals following the successful commissioning of its open-die forging press. This is the largest four-column open-die forging press in push-down design that SMS group has built in the last 25 years. The press, which operates with a forging force of up to 90 MN and an upsetting force of 108 MN, forges flat and round bars from ingots at a maximum starting material weight of 30 tons. Hitachi Metals intends to use it to process titanium alloys, tool steels, high-speed steels and nickel-based alloys.
SMS group received a contract from Chinese steel and forging company Daye Special Steel Co. Ltd. for the engineering and delivery of a high-speed hydraulic open-die forging press. The press operates with a forging force of up to 50 MN and an upsetting force of 60 MN. The high forging frequency of the press enables sophisticated materials requiring a narrow temperature range to be forged and reduces machining times. Daye Special Steel plans to use the press, which will be installed in its Huangshi plant, to forge a variety of products of high-temperature alloys and special steel. Commissioning is scheduled for May 2020.
