SIEMPELKAMP MASCHINENFABRIK GMBH

With the ring rolling mill Siempelkamp completes its range of products for the manufacture of rings. From forging the pre-forms to manufacturing the ring blanks to ring rolling, we supply everything from a single source. Siempelkamp’s ring rolling mill manufactures seamless rings made of steel and special materials such as nickel-base, titanium, or aluminium alloys using maximum radial and axial pressing forces. The radial pressing force is hydraulically generated and applied to the part via a mandrel roll. Radial rolling is carried out by reducing the roll gap between the driven external roller and the mandrel roll. The axial pressing force is also hydraulically generated and applied to the part via the upper axial roller. Axial rolling is carried out by means of the vertical forward feed of the upper axial roller. A centring device provides for the correct position of the ring during the rolling process.

Our compacting presses for titanium sponge are used in numerous dierent industries. Component parts made of titanium and titanium alloys play an important role in the aerospace industry for plane engines or highly stressed parts such as the undercarriage or supporting structures of an aircraft. Titanium is also indispensable for orthopedic applications as well as the chemical industry. The compression speed of our presses, which can be precisely adjusted to the product, oers operators highest repeat and size accuracy. Features Press capacity < 80 MN single or double-acting design automated tool change concept remote access for service support

Siempelkamp hydroforming presses are used for the production of complex and intricate workpiece shapes. This complexity relates to both longitudinal and cross sections. Next to large batch production in the automotive industry, the tting industry is one of the numerous application areas for this type of press. Compared to conventional forming methods, the forming possibilities are signicantly increased when forming with high pressure. Features hydraulic clamping forces: < 100 MN high pressure intensier: < 10.000 bar axial forces / axial cylinder: < 5 MN short cycle times due to "quick lling" systems Advantages weight savings of 40 to 50 %, in some cases up to 75 % wall thickness distribution optimized to component requirements high work-hardening continuous material grain ow for optimum component performance high dimensional accuracy
