Hybrid press brake with energy monitor
Automatic set-up and tool change are the two most valuable assets of B3 . AU-TO , Salvagnini ’ s press brake . Combining the best features of Salvagnini ’ s electric and hydraulic solutions , the B3 . AU-TO is designed to significantly extend the availability , autonomy and flexibility of the press brake .
The Salvagnini B3 . AU-TO press brake has been built to relieve the pressure on companies dealing with manual tool set-up time and downtime for feeding , programming , part manipulation and controls .
“ Available in four models , with bending lengths of up to three or four metres and maximum force of 170 or 220 tons , the B3 . AU-TO enables companies to better cope with a dynamic market which demands increasingly smaller batches , kit productions or batch-ones with very short lead times . The AU-TO automatic tool-change device and the ATA automatic tool adjuster , which adjusts the length of the stations , significantly reduce press brake re-tooling , increasing autonomy and productivity as well as reducing lead time ,” explained Nicola Artuso , Salvagnini product manager for bending technologies .
Features and capabilities
Distinctive features of the B3 . AU-TO include the Salvagnini-patented upper and lower automatic tool-change unit .
“ Additionally , AU-TO reduces set-up times and increases the availability of the press brake . The operations are rapid and in cycle , even in masked time , helping to increase the efficiency of the press brake . AU-TO makes the most out of the ATA devices , used to automatically adjust the upper and lower bending tool length ( saving time and increasing production efficiency ). AU-TO assures full flexibility for tools , because the press brake allows mixed tooling . After automatic tool change and set-up , the B3 . AU-TO enables the manual integration of standard WILA tools or special tools , such as hemming tools , on the bend line ,” outlined Nicola Artuso .
“ B3 . AU-TO has the smallest footprint on the market . The tool store is covered in the rear of the B3 . It can contain up to 24m of tools ( up to 1000mm in length ) without segmentation ,” he continued .
All the B3 press brakes are equipped with the following four features :
■ MAC3.0 : A set of integrated adaptive technologies that make the system intelligent and cancel out waste and corrections .
■ S-Crowning : The mechanical crowning system that ensures consistent bending angles along the entire bending length : the effective curvature of the lower table is measured and compensated in real-time , without any operator intervention .
■ TFC2.0 , Total Frame Control : This prevents deviations in the bending angle using an algorithm from the FEM study of each model . TFC2.0 compensates any in-cycle deformations of the press-brake structure according to variations in the characteristics of the part processed .
■ AMS : This is a laser angle measurement system that detects and corrects variations in the bending angle due to sheet metal springback . Regardless of the length of the press brake and of the part being bent , the angle is always measured in one single point ; this approach helps to reduce the cycle time without compromising on precision .
“ All these features make the B3 . AU-TO suitable for companies with a high daily item turnover rate . The AU-TO and ATA devices reduce the cycle time , making it easier to forecast , plan and monitor ,” explained Nicola Artuso .
“ B3 is a hybrid press brake . It achieves the typical tonnages of hydraulic press brakes , with the speed of electric ones . A Direct- Drive solution controls the ram movements : two independent Direct- Drive brushless motors , activated only when needed , allow the ram to reach fast approach and fast return with speeds up to 250mm / second ( depending upon the chosen B3 model ),” he added .
Impacts is Salvagnini ’ s new environmentally focused tool that measures the consumption of electricity on the B3 press brake . It is the first step towards calculating volumes of CO₂ equivalent of each single manufactured component . Users can monitor their energy consumption so they can optimise and reduce it . n
