Servopress BALCONI 2DMR-SD-200 - Maximum Customization
18th June 2018
The 200 tons model 2DMR-SD-200 servopress manufactured by Balconi for a French customer answers to specific needs thanks to a high-level of customization studied with the customer.
The manufactured machine is a 200 tons servopress with a great flexibility of use.
With 220 mm maximum stroke the press reaches 100 spm but with smaller strokes it arrives up to 180 spm in pendulum mode.
It has been named 2DMR-SD-200, acronym that specifies its technical features, i.e. straight-side, geared press, servosystem drive, 200 tons.
The mechanical has been developed by Balconi while the motor, electric power cabinets and software part has been supplied and certified in cooperation with Siemens.
It is the first servopress of small dimensions manufactured by Balconi. The project has been developed starting from a mechanical press with longitudinal shaft, a machine already installed in the production site of the customer.
In the designing phase, each department showed each own needs and requests. The customizations produced are significant for the customer and involved Balconi engineers, as each modification influences the overall machine running, thus allowing to have a product perfectly complying with the customer's needs.
Specific attention has been dedicated to brake angles as, considering the different device types, it is necessary to stop the press in safety in case of die problems. Software development engendered a specific study and, to manage all the client’s devices also giving him the possibility to make in the future modifications in complete autonomy without compromise servopress security, it has been implemented two different PLC which are interconnected one to each other. A first PLC has been dedicated to the press function safety management however, the second PLC, has been dedicated for the customer peripheral devices software (i.e. band spray lubrication, management of tapping and threading devices integrated into the dies, the several recovering and subdivision of the produced parts systems).
Soundproofing designing is also remarkable.
In addition to the soundproofing cabin also an analysis of the possible noise gateways has been made and a specific attention has been given to the acoustic insulating of all openings.
Considering the extreme precision requested from the customer’s dies it has been decided to equip the press with hydrostatic guide system without contacts instead of the traditional bronze guides. This solution, already adopted by Balconi on several machine’s types, guarantee the ram vertical movement in few centesimal.
Plunger system together with hydrostatic guides assure parallelism values and a long-life of dies, extremely increased in comparison to traditional presses.
