The Proper Framework for Tube Processing

Cover story . Effective processes with encoding, handling & co.

The peripherals


Usually, everything revolves around a system`s core. The peripherals, i. e. the environment, are usually considered close to irrelevant. In tube processing specifically, however, the peripherals of the technical details are anything but marginal. Installed for individual work processes, they ensure or sustainably secure safe processing.

Let us focus our interest on the peripherals for once. They have deserved it. The value-added chain of bending and forming, for example, ends in evaluation of the processed quality. Verification and recording of which product is currently in production or which has already been produced can be some relevant data for a secured process. Therefore, we our technologies go beyond the core processes for separating, bending, forming, cleaning or automation.

Marking and selecting

Efficient software can optimise use of the input material length during tube cutting already. The system only needs different lengths and quantity frameworks for this. It is often sensible to mark tubes as well, to render each tube unique and permit assigning it to a specific product that it will complete at a later time. Of course, tube cut to a specific length will be stored in a corresponding storage system for this sorted by type.

This, too, therefore is a valuable peripheral unit that prepares for manual or automated further processing in a forming or bending machine. The applied QR or bar code is used for identification. The corresponding machine can perform a clear assignment to the respective bending or forming geometries this way. The associated parameters are called from the system and can be adjusted temporarily.

Economic processing sequence

In other processes, it may be necessary to detect and position a weld before further processing. Additionally, prior burnouts from a laser facility can be secured and positioned manually or automatically. Of course, direct handover from a cutting facility to further processing is possible, and a storage system can be integrated into the material flow as a buffer. In terms of economic efficiency, such chronological processes generally put forming before bending.

Safe equipment processes and handling systems

We offer electronic encoding systems to properly re-equip the matching tool. The code is used to recognise the corresponding process parameters and steps. This also ensures transfer of the machine parameters. The structure of automation does not matter at all for any of these processes. It may be a manual supply, an automatic handling system or established robot systems that are programmed product- or customer-specifically by our transfluid®-specialist. These handling systems secure the entire process from loading of the parts to targeted unloading for further processing in the correct position.

Reviewing and analysing

Any desired geometry inspections can be implemented via different systems. Visual systems play a particularly important role here. They are able to measure the geometry entirely, examine a surface and review simple geometries – or to verify the presence and position of punched holes or external components. Length measurement is important here but often very easy to implement. Geometries that are more demanding or subject to a clearly defined standard may also require pressure tests.

Recording and evaluation of all of these relevant data is made possible by execution of cpk analyses. This evaluation is performed automatically and processed further in the different areas through software systems as well. Of course, clearly separated output of OK and NOK parts are sensible in the scope of the analyses as well. In some cases, this is done visually, by applying OK parts with protective caps at the tube end while leaving them off of NOK parts.

The entirety of complex processes can be controlled at any time with such systems. Therefore, later users can continue to use everything a facility like this offers innovatively for the company in future.
