T echnology U pdate

solder contours, negatively affect costs and quality of the final product. The answer to all of these production problems is consistent further development, eg of “solder batch contours”, which can be implemented using the forming technology of Rosenberger AG. Both axial forming technology on the new forming machine generation flexFORM RU8- 12-18 and radial profile rolling technology on the rolling machine series RW20 guarantee a high level of quality and performance in rough industrial everyday operation or in development centres. Technical feasibility is now provided by servo-electrical drives, since they are able to move along complex ramps, in contrast to the “blunt” moving forwards and backwards of hydraulically driven tools. The flexForm RU8-12-18 is not just a further development and merger of Rosenberger’s predecessor models RU8-12 and RU18, but rather a completely new machine concept that combines the advantages of its respective predecessors while also containing many years of experience and insights of the company’s customers. The PLC-based CNC control enables free programming of all dimensions, paths and motions up to 0.01mm, forming force and speed. Servo controllers ensure soft and precise running through the programmable speed profiles for best material flow control. Any and all material properties can be included in programming of the flexForm RU8-12-18 and considered in the production process. Thus, not only simple flanges, beads, reductions or expansions can be produced, but complex pipe end shapes can be generated as well. Tool and programme changes can be implemented in less than 5 minutes and are measured fully automatically. The servo- electrical asynchronous drives with an axial working force of up to 180kN are low- noise and -maintenance, energy saving and do not generate great exhaust heat, which leads to additional benefits in the ergonomics and energy results. A globally unique novelty is the compact build and machine concept with its vertical tool alignment (no more than 16, also multiply rotating tools) and no use of hydraulics at all; this makes the machine being easy to transport and saves a lot of footprint space. The offer includes the machine as a single, hand-operated version, master-machine and fully automatic forming device. The robot connection can be used to best integrate the machine into a fully automated system and to use it flexibly. The fully automated joining, eg of flanges, Ü-nuts, Ü-bolts, O-rings, and holders is a standard application. The model version DT (DoubleTool) enables concurrent processing of two parts, which doubles the daily output or cuts the cycle time in half.

Depending on task and parts geometry, the clamping jaws can be installed to act vertically or horizontally. The clamping unit, type of tool change and force of the axial, servo-electrical asynchronous drive can be selected and set up in modules. Possible attachment jaws enable protection of pre-formed contours or multiple contours. Several rotating tools can also be set up, so that various rotating processes like profile rolls, planes, chamfers, thread shapes, etc can be processed with great efficiency in a single programme run.

Rosenberger AG also provides the required process-safe forming tools. Interfaces that are already integrated, eg for BDE-recording, network connection for data back up and profibus interface for connection to existing systems correspond to the latest state-of-the-art. Remote maintenance can reduce standing times and downtimes to a minimum and thus warrant the basis for quick reactions by Rosenberger’s service team.

This is not a pipe.

This is not a pipe.

It’s actually an entry ticket to huge markets. Be- cause what you’re looking at is a longitudinally weld- ed pipe that’s been normalized to oil and gas pipe standards. But there’s a catch. Normalizing isn’t easy. Especially for today’s gauges and alloys. It de- mands expertise in metallurgy, control software and precise heat delivery. The good news however is that these are areas in which we specialize—making us a leader in pipe weld-seam normalizing. Also, with more than 50 years’ induction heating experience, we’re experts at using technology to open new commercial opportu- nities for our customers. It’s actually an entry ticket to huge markets.
