Accessories for the TOX®-Powerpackage
Pneumohydraulic Drive Accessories
With a variety of clever accessories, the TOX®-Powerpackage can be improved and tailored right for the application. TOX® PRESSOTECHNIK always has an eye on what the operators need and tries to develop the most functional add-ons, to improve the applicability of the pneumohydraulic drives.
The accessories shown on this page can be added to most Powerpackages. For additional features, special types may be the answer.
Accessories for special functions and easier mounting of the TOX®-Powerpackage in the press.
Electric sensors and components for measuring, displaying, and processing the data of the TOX®-Powerpackage.
The electronic pressure switch ZDO 01 provides 2 freely programmable digital outputs.
Switching function output 1 and output 2:
The switching function can be selected for each output separately. Output 2 can also be configured as diagnostic display output.
The electronic pressure switch ZDO 01.400A provides one digital and one analogue output.
Switching function output 1:
Switching function output 2:
Analogue output 4-20 mA or 0-10 V.
|13 - 2000 kN
The press force sensor ZPS can be mounted directly on the working piston of the TOX®-Powerpackage.
It is possible to measure the press forces in a push and pull direction. The sensor is sealed against dirt and moisture and should be installed with the anti-rotation device ZPSV, to avoid damage to the connection cable.

The external linear position sensor provides the absolute position of the working piston in the TOX®-Powerpackage, even after power failure. Due to the external mounting on the tie rods of the TOX®-Powerpackage, the mounting position can be adapted to the conditions inside the press.
The linear position sensor provides non-contact sensing technology resulting in the following features:
|± 10 μm
|10 ... 30 V DC
|≤ ± 0.15
|≤ 5 mA
|0 ... 10 V DC
|≤ 5 mA
When using the external linear position sensor ZHW, the effective total stroke of the TOX®-Powerpackage is to be reduced by 20 mm. The powerstroke remains the same. To achieve the described repeat accuracy and linear deviation, it is necessary to prevent the working piston of the TOX®-Powerpackage from rotating.
Most TOX®-Powerpackages can also be delivered with the internal linear position sensor ZKW.
The ZDA displays the oil pressure in the high-pressure chamber of the TOX®-Powerpackage by a 5-digit LED display. The value to be displayed is measured by the pressure sensor ZDS which is included in the scope of delivery. The ZDA is available with two digital outputs or with one digital/one analog output.
Regular maintenance of the TOX®-Powerpackage helps to increase service life and reliability.
The oil pump guarantees the optimum maintenance concept and extended maintenance intervals. For easy, air-free refilling and reduction of the oil volume of the TOX®-Powerpackage. Clear body and refill hose allow easy monitoring of the oil level in the pump. Little operator effort is required.
... and many more are described together with the special solutions of TOX®-Powerpackage.
Function: During dynamic pressure control, the automatic switch from fast approach stroke to power stroke occurs every time the working piston meets resistance at any point of the stroke. The power stroke valve is connected to the return stroke chamber via the red control throttle X line and functions according to the dynamic pressure procedure. The changeover time is controlled with the control throttle X.
There are various ways to adapt and optimize the “normal” stroke of a TOX®-Powerpackage to individual requirements.
|with ZDK and/or ZHO
With the ZKHF it is possible to release activation of the powerstroke valve utilizing dynamic pressure control with an electrical signal.
Application: If the powerstroke could be actuated accidentally by the control throttle X due to interference contours in the working area and shall thus be released additionally.
|with dynamic pressure control, ZDK, ZKHZ or ZKHF
The ZHO is an optional additional assembly for improving the cycle time. The improvement during the power stroke and power stroke aeration time is approx. 20 %.
Application: In particular if the cycle time must be reduced for long power strokes.
|with ZDK and/or ZHO
The ZKHZ enables activation of the power stroke valve with an electrically actuated 3/2-way valve.
Application: Recommended for travel dependent powerstroke connection or when using the TOX®-Powerpackage with an upward acting working rod and high tool weight. Also, for application-related, interrupted fast approach stroke.
