Schuler unveiled the first linear hammer with Servo Technology at the RUD-Sch\u00f6ttler forge shop in Hagen, Germany, last Friday. A large audience of experts from the forging industry was in attendance as the line was officially put into operation. Forging hammers were previously driven either hydraulically, pneumatically or by a flat belt. Schuler\u2019s new development, however, features a linear motor \u2013 as used, for example, by the Transrapid maglev train.
\n\u201cThanks to the new drive system, the hammer is not only regulated absolutely accurately, but also used in controlled operation more precisely than ever before,\u201d explains Schuler\u2019s Managing Director Jochen Fr\u00fch. \u201cThe ability to precisely position and flexibly control the slide opens up completely new possibilities \u2013 not only for precision forging, but also in terms of energy efficiency.\u201d A pilot project on the topic is currently being run at RUD-Sch\u00f6ttler, sponsored by Germany\u2019s Federal Ministry for the Environment.
\nWith its dosage of impact energy and in its slide control, the patented hammer drive enables an exceptionally high degree of precision in forging: the repeat accuracy of the forging blows has a divergence of less than one percent. \u201cThe new drive technology even offers the possibility of precision forging without impact areas,\u201d says Thomas H\u00fcttenhein, general manager of RUD-Sch\u00f6ttler. \u201cThis eliminates the previously standard hard-on-hard blows for balancing temperature and material fluctuations.\u201d
\nThe electronic control system automatically adjusts the energy input and number of necessary forging blows to the actual forging result after each blow \u2013 until the preselected part thickness is achieved. The influence of engraving wear on part accuracy can therefore be compensated by regulating the energy dosage. This improves product quality and makes it possible to continually document the process data.
\nReduced cycle times, increased energy efficiency<\/strong>
\nSchuler\u2019s new drive technology therefore offers maximum flexibility in adapting to increasingly specialized application areas and processes in forging. The elimination of die-to-die hard-on-hard blows means a reduction in the total number of forging blows \u2013 thus reducing cycle times and the energy needed for forming. Together with the non-contact and maintenance-free linear drive, which directly converts electrical energy into the mechanical movement of the hammer slide, the potential energy savings are up to 20 percent. Thus, energy efficiency reaches a value of more than 90 percent.
\nPrecise control of the upper slide also enables the integration of stretching and rolling blows, as well as bending operations, into the actual forging process under the hammer. In the case of low impact energies, the linear motor can be started from any position and thus also reduces cycle times by eliminating unnecessarily long slide strokes. This greatly increases the potential areas of application. The ability to precisely control the linear drive means that the new linear hammer is ideal for automation with robots.
\nIn addition, there is no more need for all previous components used to generate compressed air or hydraulic storage energy. As a result, the hammer is also virtually maintenance-free. \u201cBy avoiding hard-on-hard blows on the impact surfaces, the load on die and hammer is also drastically reduced. This leads to a reduction in noise emissions and thus opens up the possibility \u2013 in combination with conventional soundproofing \u2013 of three-shift operation,\u201d Thomas H\u00fcttenhein concludes.
