Our straightening presses process heavy plates, slabs, and bars. Next to classic solutions providing a press force of 1,500 to 2,500 t,<br />
we also offer concepts with a press force of up to 6,500 t (7,165 US tons).<br />
<strong>Siempelkamp</strong> pipe-forming presses manufacture large-sized, longitudinal-welded pipes for pipelines. During the crimping, U-forming,<br />
and O-forming processes a press force of up to 720 MN is applied. These presses get the job done when it comes to the production of<br />
large pipes for pipelines and offshore applications. Due to the automatic ram parallelism control of our pipe forming presses, even pipes<br />
with a length of up to 18 m (59 ft) are produced with high precision.<br />
For many applications our presses have become an integral part, for example, presses for heat exchanger plates which are used in<br />
the food industry. Special parts used in the aerospace industry are manufactured on our rubber pad presses. These presses operate<br />
according to the Guerin process with up to 260 MN.<br />
Our hydro-forming presses economically produce complex workpieces. This complexity relates to both longitudinal and cross sections.<br />
Typical examples include chassis parts, branching elements of tubes, and frame and exhaust parts for the automobile industry. For rear<br />
axle members, lightweight frames or large series production, our presses are designed to meet the needs and general conditions of our<br />
customers.<br />
Straightening press Dillinger Hütte<br />
Straightening press for Dillinger Hüttenwerke AG<br />
In July <strong>2009</strong> we started the installation of a new heavy-plate<br />
straightening press for the heavy-plate rolling mill facility at<br />
Dillinger Hüttenwerke AG. This press is designed for high-strength<br />
rolled plates with a thickness ranging from 50 to 300 mm. These<br />
plates have a width ranging from 1,000 to 5,200 mm, are up to<br />
19,000 mm (62 ft) long and can weigh up to 60 t (66 US tons).<br />
The upper bolster of the press is equipped with two movable<br />
rams that have a press force of 32.5 MN each. Their cylinders are<br />
servo-hydraulically controlled. Each cylinder pair can be moved<br />
individually or simultaneously. Mounted beneath each pair of<br />
cylinders is an individual ram tool for straightening. A special<br />
feature: An aligning tool allows the connection of both hydraulic<br />
cylinder pairs. By using the aligning tool, 100% of the press force,<br />
65 MN, can act on the plate.<br />
The maximum straightening force can be applied up to the plate<br />
edges which means up to 2,600 mm (8.5 ft) from the press<br />
center line.<br />
<strong>Siempelkamp</strong> supplies the new press as a complete package<br />
including installation and start-up. Our straightening specialists<br />
are supporting the commencement of production at Dillingen.<br />
Furthermore, the scope of supply also includes the supporting<br />
equipment for the manipulating, lifting, lowering, and transversing<br />
of the plates. The entire oil-hydraulic and electronic<br />
controls for the straightening press were also designed and built<br />
at <strong>Siempelkamp</strong>.
