FACE TO FACE

PivaPunch and PivaBend

Pivatic ’ s PivaPunch punching machines utilise direct material flow to maximise efficiency and offer a variety of options for production .
“ They are best suited for product families and symmetrical parts with batch sizes ranging from one to several thousand . A single batch can be produced in as little as a couple of hours ,” explained Pivatic .
PivaBend bending machines are equipped for profile , panel or casingtype parts . They are suitable for product families that require fast cycle times . The parts are pre-programmed and tested via Factory Acceptance Tests . A typical bending line has a wing-former for each side of the part . Utilising this technology as part of a continuous process , said Pivatic , results in low cycle times .
“ PivaPunch and PivaBend can be combined to make your products complete in one run as well as save space and reduce labour costs . Integrating separate modules and other production equipment ( such as press brakes , perforating presses or panel benders ) makes it possible to gain more efficiency and flexibility ,” added Pivatic .
customers at this important exhibition ,” he added .
Pivatic showcased a fully automated servoelectric coil punching , cutting and pressing line on its stand . Servo technology is also designed to lower maintenance costs and noise levels . “ Highly indexable Thick Turret punching , combined with a separate cutting station and a press tool station with 1200kN punching force , enables jobs ( such as hole group , embossing , corner notching and trimming ) to be flexibly produced ,” explained Jan Tapanainen . “ Energy consumption for the full line is between 12-18kWh , depending upon the use of the large press which is 60-70 % less compared to traditional systems . This supports our low-energy product solutions towards global sustainable development . Energy consumption really matters , as do reduced waste levels . Customers want to use every metre of the coil material nowadays to be as efficient as possible .”
The line has been bought by a German manufacturer who was due to take delivery of it after the exhibition with two coil cars , a turning drum and a stacking device .
The electric PCC-e punching centres utilise servo technology for significant energy savings . Both force and stroke of a plate ram , driven by a linear motor , can be CNCcontrolled . That means rapid punching with less energy consumption . Pivatic punching lines reclaim the braking energy of the servo motors in punching stations and presses and re-use it in the process .
“ The electro-servo , coil-punching line here at EuroBLECH is fully servo-electric , connected to a 30-ton press and a 120-ton electric press and electric shear . We are bringing a ‘ green ’ theme to the show , encouraging visitors to turn over a new green ‘ leaf ’, as this line offers very low energy consumption ( 60-70 % energy savings compare to many conventional technologies , which mean yearly savings of up to € 40-50k , at current electricity prices , in three-shift operations ). As energy prices spiral and are expected to remain high for the next few years , we see a lot of energy-saving potential here ,” outlined Pivatic CTO , Mika Virtanen .
“ In terms of sustainable materials , we are also using SSAB sustainably produced GreenCoat coil materials with our electric punching machines . Our lines can last 30-35 years with modernisations and upgrades . That lifecycle is better than most . We are

continuously working on systems using less oil , lower energy consumption and intelligent electric drives to bring value to the customer ,” he added .
The automation factor
The shortage of skilled workers and operators in global markets is hitting hard in many countries , so technology providers such as Pivatic have to fill these gaps with its equipment . Software and automation are key parts of this equation .
“ Measurement and monitoring technologies , plus machine feedback , are now part of the environment in which we operate . This year , we added robots and automated systems to our portfolio . This means that we can offer customers secondary processes in the line such as joining ; bending ; assembly ; stacking ; packing ; automatic quality measurements and part handling etc . We use different brands of robots for this ,” confirmed Jan Tapanainen .
Pivatic has employed robots in its lines to move parts and further processes such as welding or sorting , but now they are increasingly used in the systems themselves to handle material flows . Robot integration has become a widely used option in full process system implementation . For example , with
