Fewer steps to the finished workpiece With t project you can see all the variables of the bending process before you start the production. Adapted to the material and collisionfree, it makes it possible to plan and execute complex bending geometries. The virtual bending simulation determines exact bending timings and cutting lengths; it also tests tube geometries in advance for feasibility. Tube data and bending results are documented with accuracy and they can then be replicated 100% . All the most common interfaces are available for the import and export of data and connection to BDE or ERP over the network.

Labelling systems can be integrated, whether it is laser, needle or inkjet, to mark and identify the tubes. Other options that can be integrated are welding seam detection, length control or measurement of processed tubes. The corresponding sensor and camera technology can be implemented for the specific product. The following step can be carried out without any problems, whether it is cutting, punching, deburring of holes or seal testing with external systems. Smart data evaluation All the systems can be equipped with different control and IPC panels. Interfaces to data caption systems for consumption and operation make the digitalization and evaluation of the data.

The right system for every need There is a great variety of handling systems available, dependent on the length of the workpiece. For short tubes there are systems gripping from below with insertion axis and for long tubes there are systems handling from above. Both options can be used in our combination systems. They guarantee ideal access for the operator, so they can complete the setup and any maintenance operations in the best possible way. Transfer stations, turning modules for processing the tube in both directions within an installation and multiple grippers are available for optimized processes. Handling robots from many different manufacturers can also be integrated. The robots are used to move tubes/workpieces. A preassembly of different workpieces is also feasible in this case. The various components can be sorted using sensors and robots.

We offer a great variety of loading systems for all the machines, dependent on the material, tube diameter and tube length. Tubes that have already been formed and with added components can also be loaded without any issues. The appropriate orientation is therefore very important, when loading the tube into the production cell. External workpieces, such as nuts, flanges, supporting sleeves can be added to the system in a controlled manner and included in any subsequent processing steps. A great variety of loading volumes is possible. Step feeder, Conveyor feeder, Chain feeder, Swivel arm feeder, Loading tables, Bowl feeder, Alignment station
