Tandem Pressline

Task

Automation of a press tandem line consisting of 4 single presses for the manufacture of large surface automobile parts with a max. blank size of 4300mm x 2000mm. Direct transfer of parts from press to press with a distance of 7,2m without intermediate storage. Press line in permanent stroke mode (without stop at TDC) with up to 12 strokes per minute.

Solution

The electronically synchronized press line operates at a mutual angle offset of approx. 30° depending on the stroke. Parts are transferred from press to press with the GÜDEL crossbar-system roboBeam RBS. The 5, free-standing units move angle synchronized to the relevant press. Due to the specially optimized paths of motion, large parts can be accelerated up to 30m/s2 and up to a max. speed of 8m/s. Thanks to the continuous operation of the press line without stop at TDC, the load on the coupling/braking unit of the press is reduced to a minimum. Tooling changes are performed automatically.

Scope of supply

5 RBS roboBeam units -- a system desigend for the transfer of large surface blanks with a max. distance between the prsses of up to 8500mm without the use of an idle station.

Result

The tandem press line run with a output up to 12 parts/per minute. Thanks to the continuous operation of the press line without stop at TDC, the load on the coupling/braking unit of the press is reduced to a minimum. Tooling changes are performed automatically.
