Description
Compact™ Straight Punch Driver
The
hand-operated hydraulic devices for making holes of different shapes in soft to medium-strength steel, stainless
steel and aluminium sheets. ALFRA punch drivers are low-maintenance thanks to the closed hydraulic circuit and
enable you to work with in any position.
The hand lever (F) and the stable handle (E) are designed on ergonomic principles to ensure perfect handling of
the punch driver. Working pressure inside the pump body (D) and the cylinder (B) is built up and released by the
drain screw (C). The drain screw (C) can be opened by turning it to the left into the OFF position and closed by
turning it to the right into the ON position. By pressing the hand lever (F) when the drain screw (C) is closed, the
necessary working pressure is built up, which pulls the load piston (A) inwards into the cylinder (B) with great force.
The pressure is released by opening the drain screw (C) and the load piston (A) is pushed back into its starting
position by means of an internal spring. The integrated excess pressure valve limits the maximum attainable
pressure within the device and protects the hydraulic punch from excessive use and damage.
Perfect punching results are achieved using the suitable ALFRA tools. An overview of our range of quality round
and square punches can be found at the end of this operating manual.
