FOCUS ON STAMPING
DEES HD-2500 tandem press line with robotic arm feeder .
presses such as custom triple-action ; diespotting ; die-tryout ; deep-drawing ; transfer ; servo-controlled ; tandem press line ; hotforming ; four-post ; hemming ; C-frame hydraulic presses etc . Its focus is on three main stamping areas : servo motors , higher speed of the hydraulic press and higher productivity for presses , using accumulators for shorter strokes . DEES Hydraulic has also successfully developed a closed loop , hydraulic , servocontrolled , die-spotting press .
DEES has introduced a 24-hour 2,500- ton tandem line customised for automotive manufacturing industry . The hydraulic monoblock system is powered by a motor and pump set . The moving bolsters are enhanced with a QDS system ( quick die-change system ) to make the heavy die-change easier and faster . Users can adjust pressure , speed , daylight and stroke distance .
The high-speed technology of the HD series developed by DEES is controlled by the accumulator . Its pressing speed is between 30-150mm / second , with an approaching speed of 800mm / second or faster and return speed of 600mm / second or faster . With the cushion system function to knock out the parts , all speeds and strokes including the slide and cushion systems are adjustable . DEES ’ s selfdeveloped HD-FASTech technology has been designed to improve deep drawing / production efficiency .
AT JEC2024 in March this year , Dieffenbacher showcased processes including Sheet Moulding Compound ( SMC ) and GMT and its Tailored Blank Line , including tape-laying and consolidation technologies . The company ’ s core competence , the hydraulic press , plays a major role in all these processes . Its press lines feature press forces of up to 32,000kN . The manufacturer ’ s digitalisation platform , EVORIS , uses artificial intelligence to make production lines faster and more efficient .
“ Our adaptive accumulator management of the press ’ s hydraulic drive system optimises the energy consumption of hydraulic press systems by automatically determining , during the first press strokes , the exact energy required for forming . For subsequent production cycles , the hydraulic drive accumulator is charged only to the corresponding required pressure level ,” it said .
The company celebrated its 150th anniversary in 2023 . ebu Umformtechnik ( ebu ) designs automatic punching machines , presses and automation from the conveyor system to parts management . It showcased its HMI ( humanmachine interface ) with Siemens Unified Panel at the Blechexpo 2023 exhibition in Stuttgart . The HMI is cloud- and web-ready and multi-touch gestures as well as zooming functionality is possible .
Fagor Arrasate , headquartered in Spain , offers presses , coil cutting and processing lines , and complete systems for manufacturing complex metal parts . It also specialises in composite forming , hot and cold forging systems , and press hardening . It is part of the Mondragon Corporation . It recently acquired a 70 % stake in Spanish company , Ribinerf , which specialises in industrial robotics , 3D vision and artificial intelligence to automate part quality control , sorting , picking and racking processes . Fagor Arrasate designs and manufactures presses and stamping systems from 630KN up to 150,000KN using mechanical , hydraulic or servo-driven technology . It has been supplying transfer presses for more than 30 years as
Fagor Arrasate ’ s new online teleassistance service for customers .
well as manufacturing large transfer presses of more than 3,500 tons .
Its presses are fully automated , with its own automated systems such as transfer systems or pick-up destackers . It also offers one single control architecture for an entire press line . Its high-speed press line ( WaveLine concept ) has been developed to transfer large , stamped parts ( such as body side , hood , roof and double-door units ) through large tandem press lines . Fagor Arrasate has also incorporated Danobat ’ s coil laser-cutting technology into its press lines . It offers a modular and scalable coil-fed laser blanking concept .
Its new online teleassistance platform streamlines the contact and transmission of information between customers and Fagor Arrasate technicians , without intermediaries , through a simple and intuitive form that can reportedly be accessed from any device anywhere in the world .
FF Fluid Forming GmbH produces the FormBalancer hydroforming press . It shapes metal sheets into a tool mould by applying very high pressures ( up to 4000 bars ). The clamping forces of up to 8,000 tons required in this process are completely absorbed by the machine frame without any deformation of the tools , it told ISMR .
Turkish manufacturer , Hidrokar Pres Metal Makina İml . San . İç ve Dış Tic , manufactures a range of presses in different formats and dimensions , including hydraulic and deep drawing presses .
Fresan Makina san . ve Tic . Ltd . Sti manufactures C-frame eccentric presses from 10 tons to 250 tons ( 100kN - 2500kN ), special machinery and hydraulic punching presses .
Group Rhodes is one of Europe ’ s largest original equipment manufacturers in its field and celebrates its 200th anniversary this year . It has been granted patents in Europe and China for its Superplastic Forming ( SPF ) and Diffusion Bonding ( DB ) technology . This technology , which is used in the production of large , complex components , involves the diffusion bonding of multiple layers of titanium sheet at selected points , which can then be super-plastically formed using inert ( argon ) gas to inflate the sheets into the shape of a hollow die . This process is extremely temperature- and pressure-sensitive and allows for the creation of much more complex shapes , no springback
