France’s Obut has been producing steel balls weighing around 700 grams each for popular sport Pétanque since 1955. In an effort to improve production of boule balls at its headquarters in Saint-Bonnet-Le-Château, the company ordered a 1,300-ton forging press from Farina. The forging press replaces two lines with a press force of 600 and 800 tons respectively, which are becoming obsolete. The future line, which also includes a transfer and a furnace, will form a half shell every 2 seconds. The starting material for the boule balls, which have a diameter of just over 2.75 inches (7 cm), are steel rods cut into sections that a press first forms into discs and then into half shells. These are then welded together, machined and polished to a mirror finish.
Italian ring and bevel gear manufacturer Molla has been evaluating forging presses from Schuler's subsidiary Farina to produce its products for use in trucks and construction and agricultural machinery. Following successful preliminary acceptance, a 10,000-ton line will be on its way to the company’s facility in Solbiate Arno this summer. Molla currently operates a 6,000-ton press and a 1,000-ton press. The three machines form a forging cell for preforming, deburring and finish forging of rings. This cell will increase Molla’s production capacity in preparation for future market requirements.
A. Benevenuta & C. S.p.a. ordered a 2,500-ton mechanical forging press from Farina, a Schuler affiliate. The company produces hot-forged steel components for the automotive industry near Turin, Italy. The parts are used in suspension systems, transmissions, engines and brakes in passenger cars, tractors, trucks and earth-moving machinery. The press force of the Benevenuta production lines ranges from 1,200 to 2,500 metric tons.
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.
