FOCUS ON STAMPING
AIDA ’ s DSF-NE2-4000 servo press .
AIDA debuted its NSX mechanical stamping press at FABTECH 2023 in Chicago , USA , last September .
Two product lines that are dedicated to the production of motor laminations are the AIDA HMX Series and AIDA MSP Series presses . The AIDA MSP press enables users to produce motors such as EV motors , HEV motors and energy-efficient home appliance motors . AIDA ’ s DSF-TE4 servo transfer presses ( double-column split presses designed for transfer applications ) offer high levels of customisation through multiple configurations .
Swedish press specialist , AP & T , has introduced a new version of its servohydraulic press with even lower energy consumption than before . The new version is primarily intended for progressive die stamping which requires a large number of strokes per minute and for other types of forming requiring precision such as embossing , punching and deep drawing .
AP & T ’ s engineers have equipped the press with a closed , robust hydraulic system with a small oil volume and few components . Thanks to the modular system , each press can be optimised to use one or more cylinders depending upon the application .
“ We are also introducing a new Android-based tool that simplifies remote problem solving and reduces the risk of misunderstandings and downtime ,” added AP & T .
AP & T has also added factory-rebuilt presses to its customer offering . These are older machines that AP & T ’ s facility in Tranemo , Sweden have rebuilt and upgraded to meet current performance and safety requirements . The press specialist has also created an automated blank unloading and stacking system for one of its U . S . customers .
To meet the automotive industry ’ s
increasing needs for larger and more complex press-hardened components , AP & T and ArcelorMittal recently decided to deepen their collaboration .
Italian manufacturer Balconi Presseccentriche S . p . A . produces transfer , blanking and servo presses as well as presses for progressive tools , impact extrusion presses and fin die presses . Its press model 4DMRF-LD-2000 has a 2,000kN cushion and three-axis electronic transfer . The press can produce up to 27 strokes per minute .
Boldrini ( part of the Faccin Group ) is a manufacturer of hydraulic dished-end presses , flanging machines and manipulators . The presses feature high speeds including approach , return and , particularly , pressure build-up timing that , it told ISMR , results in a substantial increase in head production .
Its heavy-duty ,
four-column , dual-use hydraulic deep drawing press has a capacity up to 5000 tons .
The newly launched BSTL 350-88 press from Bruderer AG .
Balconi servo technology .
The ROTEX design combines a hot forming press with a hot flanging machine capable of forming heads of up to 200mm in thickness .
Its manufacturing line includes specially designed hydraulic presses with one or more independent cylinders used for folding , straightening and shaping of components for naval , aircraft and aerospace applications . Hydroforming and / or air forming presses , used for multiple purposes , are also available .
Swiss stamping specialist , Bruderer AG , unveiled two new presses at the Blechexpo exhibition in Stuttgart , Germany , last November . It introduced the BSTA 710-220 and the BSTL 350-88 models ( the latter for customers involved in volume production of small and miniature components ).
“ As a fixed-stroke press , the BSTL uses up to 30 % less energy when compared to older machine models . It comes with a new-generation servo feed unit ,” commented Bruderer .
The BSTA 710-220 , said Bruderer , offers “ the longest bed length ( 2.2 metres ) of its machine type in the world .” With automatic stroke adjustment and various options such as different stroke lengths , shut heights and press force monitoring ( for example ), the press can be configured for individual customer requirements .
AP & T ’ s first press-hardening line in India is now operational at ALF Engineering in Khed City ( Pune ).
