THE PV21: HOT FORGING PRESS DIMENSIONS
THE NARGESA PV21 FEATURES
Machined Table
The press table is machined, which ensures it’s perfectly parallel unlike most presses on the market which are guided by beams or lateral iron structures that don’t guarantee parallelism or accuracy during the drop. The PV21 press is guided with four 55 mm chrome-plated columns to ensure nothing alters the sides.
Vertical Drop
Many presses operate upwards, forcing operators to move their arms up and down while guiding the piece. This makes the process even more difficult and is by no means necessary for good work. On the contrary, the PV21 forging press drops vertically, always keeping the piece secure on the bottom ta-ble which facilitates and speeds up the hot forging work.
Manual & Automatic
When in manual mode, the press only drops when the pedal is pressed down. It remains in a fixed po-sition as soon as the operator’s foot is lifted. This means of operation is particularly useful when doing very delicate work or to center a custom mold. With automatic operation, the machine drops to the lower limit switch or until the operator’s foot comes off the pedal. Then, it automatically moves up to the top limit switch. If the pedal is pressed down, the press drops and rises repetitively to each limit switch, which can be adjusted to delimit the movement to the minimum necessary for each specific job. This boosts productivity.
Top & Bottom Limit Switches
Many modern presses are activated with a side lever with no limit switches, which means operators always have their hand busy. This makes it quite diffi-cult to make two similar pieces.
To overcome this problem, the PV21 press features 2 adjustable limit switches on one side. The bottom limit switch allows you to adjust the top position, lea-ving the opening just right for more productive work.
Easy Custom Mold Production
There are no limits to the types of jobs that need to be done meaning you often have to customize molds to save time and money. Prada Nargesa supplies the machine with two additional sets of self-centering plates to weld or screw on any type of custom mold.
Safety & CE Marking
The PV21 has a safety pedal with a fold-down tongue which prevents the machine from being accidently started. The machine is also equipped with front and back adjustable protective devices that lower the possibility of getting hit with fragments without lo-sing visibility at any time. Plus, the emergency stop button, which is fully accessible throughout the work, and other complementary safety mechanisms make the PV21 forging press more than compliant with all EC machinery manufacturing standards.
Versatility
The large work table and 250 mm x 296 mm, or 10” x 10.2” opening make it so operators can work with two molds next to each other at the same time. This is particularly useful for producing knives, swords and forged items like hammers, pliers, etc. All molds are self-centering for easier error-free positioning. It takes no more than 60 seconds to switch any of them.
