Berger Tools Ltd are pleased to supply Multicyl air over oil presses.
Multicyl cylinders are a patented brand of air over oil press used for a variety of metalworking applications. The most common is hole punching, but Multicyl is an excellent solution to many other types of manufacturing applications such as notching, shearing, tube piercing, assembly and metal joining.
Before getting started, double check that the Multicyl meets the following two criteria:
Does the Multicyl fulfil the tonnage requirements of the tool/application? shear length x material thickness x tensile strength = force (for shaped holes) PI x diameter x material thickness x tensile strength = force (for round holes) shear length x thickness x 3500 = stripping force (approx) Mutlicyls are rated at 120 PSI, the force output adjusts proportionately with the incoming air pressure level
Does the Multicyl fulfil the stroke requirements of the tool/application? the advance portion of the stroke (overall stroke - power stroke) must be long enough to position the tool in place the power stroke must be long enough to do the work.
In order to account for application variables (air pressure, material conditions, punch sharpness, tool and/or frame deflection, etc.), and to ensure a longer machine life (no machine should consistently run at 100% output), a safety margin of 25% should be applied to both stroke and tonnage requirement calculations.
