Cylinder bending - Import export

Please contact us for detailed information and offer.

With our four-roll cylinder bending machines, we can perform cylinder bending for parts that are 3 meters in length, 150mm to 600 mm in diameter. And maximum thickness is 15 mm.

Displacement sensors models 8710 and 8711 with resistance tracks made of conductive plastic material are designed for a direct and accurate measuring of mechanical displacements. A special ball joint coupling is mountable on both ends of the driving rod. Because of this the sensor may be used free of clearance or lateral forces also with angular or parallel misalignment between sensor and measuring device. A special multi-fingered slider provides a good electrical contact also at high adjustment speeds or vibrations. Areas of application are: —Electromagnets —Switch and button deflections —Pneumatic cylinders —Press-fits (longitudinal press-fits) —Hydraulic cylinders —Measurements of deformation and bending —Length tolerances —Feeding paths Due to the technology employed in potentiometric displacement sensors, they always operate with a sliding contact system.

Due to its high resolution also when measuring long distances, linear displacement measurements up to 900 mm can be carried out. Conversions between rotatory and translation movements through ball screws, wire or cord connections and so on are not necessary for direct displacement measurement. Application fields include: —Electromagnets —Deformations - bending —Pneumatic cylinders —Length tolerances —Press-insertions (longitudinal press-fits) —Feed strokes —Machine hubs —Punch, knee lever or extruder distances —Hydraulic cylinders Due to the technology employed in potentiometric displacement sensors, they always operate with a sliding contact system. Special processes are applied to give the resistance tracks low friction, low tendency to stick/slip, resistance to abrasion and long-term stability. The rod is guided in a low-play floating frontal bearing. This absorbs small angular and parallel displacements.

We bend metal sheets on numerically controlled (CNC) bending machines from AMADA, LVD, PROMECAN, DURMA. In addition to bending sheets in a straight line, we also perform profiling on cylinders and bending pipes and profiles. We have 9 CNC press brakes, on which we can bend elements up to a length of 4 meters. Our largest press has 4 meters of working length and 320 tons of pressure. In the near future, our machine park will be enriched with a robotic station for bending sheets with an Amada press with a length of 4 meters and a pressure of 220 tons.

EHRT's standard bending machine EB 40 is distinguished by their extreme robustness and simple handling. The machine is modulary and flexibly structured, so that each machine can be individually adapted to the customers’ needs. EHRT bending machines can perform a multitude of bending modes. Offset bending, flat bending, edge bending, torsion bending, closed shapes and U-bends are some examples. The hydraulic cylinder of the bending machine is fitted with a force of 344 kN. The machine offers an outstanding bending accuracy of 0.2°. A special plug-in system makes tool changing very user-friendly on the EHRT machines. This guarantees very fast setup times and yet robust and precise bending tools. Beckhoff's PLC machine control enables machine maintenance and software updates via remote access.
