Advantages of TE-presses
STENHØJ TE-presses are stable C-frame presses and are excellently suited to continuous operations in everyday production.
The robust welded construction form enables optimal access in the working area.
Using the large selection of available accessories the machine can be adapted to various requirements.

Customised models
Should your application demand alterations to the die installation height, clamping surface, working radius, stroke length, require alternative control options; or call for other special electrical or additional hydraulic equipment, we can offer you an extensive range of special equipment.

Press frames
Low press frame expansion is a basic condition for our TE-model C-frame presses. Therefore we have equipped the press frames with a solid, bend-free welded steel design. The frame is made in one piece, and being rigid and fracture-free therefore has the required high stability.

Cylinder and guidance
Exact guiding and good seal components are important for press cylinders. For this purpose we use high quality, expertly processed steel tube having a cylinder surface which is either roller polished or honed. The piston rod is ground and hardchrome plated.
The special low sear material of the guide bushing between the piston and the cylinder ensures precise guidance.
This guarantees our presses – together with reliable, low-wear and proven seal elements – a long working life.

Ram specifications (PP)
Depending on the working task requirements our customers may choose between three ram constructions.
TE-presses with standard specifications are equipped with a ram plate having 2 guide columns.
Higher guide accuracy is achieved by equipping the ram plate with 4 guide columns.
For the ultimate stability and most exact guiding for cases involving offcentre loads, there is a ram available in a welded box construction with a 6 flat guide system.

Bed plate and ram plate
The well dimensioned bed plate and the ram plate are equipped with t-slots for clamping the dies. The ram plate is guided by two strong columns and has a shank screw for positioning the die.

Operational ergonomics
A modern concept and mature design are preconditions for optimal ergonomics. Therefore we have placed all the operating controls in visible and accessible positions, so that machine operation is not only simple and safe, but also ergonomic by nature.

Hydraulics – an efficient drive system
The hydraulic power unit, located in the main machine body of the press, is easily accessible and service friendly. The pump system in the standard version is equipped with a 2 stage pump unit.
A high pressure pump is used for high press forces. The delivery quantity for fast feed and the low pressure speed is achieved using a low pressure pump having a pressure-dependent switch-off.
In this way only a minimal amount of drive power is required at full press force.
With high performance machines, the pump system can be supplied with a variable displacement pump. Pump noise is minimised by mounting the pumps directly in the oil container.
The valves are mounted in a compact block form – positioned on the oil reservoir – and are conceived as a safety control fulfilling the current safety regulations.

Electrical control
The control must be user and operator friendly. The relay controls in our TE-presses take this into account. And naturally they comply with the European standard EN 60204 and the most recent accident-prevention regulations according to the European health and safety regulations.
According to the safety requirements, the control is fitted with 2 channels for monitoring the operation and stop functions.
The large-dimensioned switching cabinet is mounted on the press side support. Inside are all the electrical control elements installed fully visible and easily accessible.
The different functions of the TE-presses are switched via a panel mounted key switch.

The operation modes are:

• Inching and
• 2-hand-operation

As options the operational modes:
Foot mode (FB)
Via foot pedal with cable,
Automatic mode (AU)
With control link for peripheral units and
Operation with light guard (LG)
are available.

Press force regulation
The desired press force can be set finely and infinitely using the pressure control valve located under the gauge.
The press force is displayed on a glycerine damped gauge which is graduated in tons and kN. The gauge can be disconnected via an isolator valve.

Stroke setting
The graduated scale for the stroke setting – consisting of three cams – is located on the front side of the press. On the middle and right scales upper and lower stop positions can be infinitely set.
The left scale serves to switch from approach speed over to press mode. The setting of the scale lever is carried out using an allen key during the set-up operation.

Programmable control
For customers who need more control, programming and data storage our company offers 2 versions: TP177, and MP277.
The control system which are based on Siemens' PLC equipment and enables the press forces, speeds, and positions in 1, 2 or 3 axes to be preprogrammed. (Subject to version).
The speeds can be selected either in fixed steps or steplessly – depending upon which hydraulic unit is in use. The MP277 is freely programmable which means that the potential of a modern multi-axes press can be fully exploited.
The control panel with its part and full graphic displays offers comfortable machine monitoring. Softkeys and function keys enable safe and efficient operation. The functions of the press are continuously displayed as well as operational and error messages. Error messages are given out in text form in the language respectively selected by the operator.
Programming faults are immediately signalled and can be effortlessly corrected.
The extended die cushion functions enable a distance- dependent variable die cushion pressure.
In this way the die cushion function can be optimised. Peripheral equipment, e.g. coil feed, can be exactly controlled using programmable inputs and outputs.
