Open-die forging<br />
Open-die forging press for airplane structural parts<br />
made of aluminum alloys<br />
In the beginning of <strong>2009</strong> we received the order for an open-die<br />
forging press with a press capacity of 25 MN for forging and<br />
30 MN for upset forging. This press has been designed for the<br />
open-die forging and bend-forming of aluminum alloys for the<br />
aircraft industry. The 2-column open-die forging press will manufacture<br />
fi nished forgings or semi-fi nished forgings to be used in<br />
subsequent closed-die forging processes.<br />
A technical highlight is that the central press cylinder is integrated<br />
into the upper beam and the piston is mortised into the moving<br />
beam. In connection with a guiding system in the x-axis, this<br />
design guarantees exact guidance of the movable beam over the<br />
entire press stroke even at high eccentric loads.<br />
The advantages of this press design for the customer include<br />
short delivery times, higher throughputs, improved quality of the<br />
forgings and, at the same time, higher reliability.<br />

Three open-die forging presses for China<br />
In <strong>2009</strong> we installed an open-die forging press for titanium at<br />
Goldsky Titanium Industry Technology & Co. in the Chinese Hunan<br />
province. Because of the tight temperature range which has to be<br />
kept when forging titanium, the Chinese customer made their<br />
buying decision depend upon the high forging frequency of the<br />
press. With the new machine that has a press capacity of 40/45<br />
MN, Goldsky will forge rods, square bars, fl at bars, tool blocks,<br />
fl anges, washers and pins. The press will start operation in mid-<br />
2010. Key data include:<br />
• specifi c control concept for hydraulics and electrical<br />
engineering<br />
• integrated control of forging manipulators which are working<br />
synchronously with the press for perfect product handling<br />
• visualization of process data during forging via Prod-IQ ® Metal<br />
Forming<br />
Two customers from China – Dongbei and Fushun – also decided<br />
to order an open-die forging press each. Dongbei Special Steel<br />
Group Co., Ltd. will receive a 35/40 MN design for which parts<br />
were produced in <strong>2009</strong>. This customer will use the press for ring<br />
forging, round forging, and fl at forging. Designed as a 2-column<br />
push-down press, this <strong>Siempelkamp</strong> product is able to perform<br />
more than 100 strokes per minute.<br />
The <strong>Siempelkamp</strong> scope of supply includes the construction of<br />
the entire plant, manufacture and supply of all other components<br />
and installation of the press in China. The installation is scheduled<br />
to begin in mid-2010.<br />
We received a new order from Fushun Special Steel Co., Ltd. in<br />
July <strong>2009</strong>: The company ordered a 2-column open-die forging<br />
press with a press force of 31.5/35 MN. Also included in the<br />
scope of supply are the hydraulics, electrical system, tie bars,<br />
pistons and cylinders. In the Chinese province of Liaoning, the<br />
press will forge parts made of carbon steel, stainless steel and
