Pneumatic and hydraulic tool units
In addition to the press-operated tool units, a large number of punching units, notch units and cut-off units equipped with their own drive are offered in this catalogue.
These units do not require a press.
They are equipped either with powerful, patented pneumatic power cylinders or with double-action hydraulic cylinders.
Pneumatic or hydraulic tool units can be used wherever there is no suitable press available or the appropriate press is being used for other parts.
The tool units are suitable for processing big, bulky and moulded workpieces which are processed outside the press area, i.e. the units can be used at any location.
The only prerequisite is the availability of air or oil pressure.
The restrictions on pneumatic or hydraulic tool units are the load capacity and the cutting force required. Prior to using these units it is, therefore, necessary to determine the cutting force. The cutting force charts provide a quick overview.
As shown in the illustration, the most important difference to the press-operated tool units is the top mounted drive cylinder.
The cutting process for punching, notching and cutting is the same as that which has been described for the press-independent tool units.
In contrast to tool units which operate independently from presses, the tool frame has to withstand the effective cutting force during processing. Solid construction of the tool frames is, therefore, a prerequisite. For this reason the height of the material support for these tool units is 125 mm.
