Hydraulico

Advanced rail forging lines, rails and switches

Hydraulico offers a complete solution, including a 5,000t press with specially developed dies and an advanced computer-controlled handling and manipulating system that boosts productivity for rail manufacturers worldwide.

Benefits of the advanced rail forging line include a 75% reduction in manpower, 65% decrease in milling and a saving of more than 50% in energy costs. The product also saves time and energy in post-heat treatments.

The line perfectly produces 4-8 forged rails an hour, which is an impressive productivity rate when compared with the 1-2 rails an hour of many existing systems. In addition to the time savings in machining, capacity during the milling process is also increased.

Deep drawing presses and electronic shimming

Hydraulico’s state-of-the-art presses are unmatched in efficiency. Well-designed, durable and versatile, presses range in capacity from 100t to 5,000t and customised presses are available for specific client requirements.

The company also has intelligent technologies to improve deep drawing capabilities, known as electronic shimming, which lowers scrap rates, facilitates production control and allows for quick and easy tool changing.

Die forging optimisation tools

To meet the specifications for high-speed train rails, it is crucial to avoid any wrinkling, shrinking or lack of filling of the forged shape. The information gained from the FEM analysis is imperative when designing the forging dies. Developed computer simulations clearly show the performance of the dies and the necessary forging parameters.

The advantages include an improved performance of the forging operation, an extended die life and significant costs savings in testing and commission. The design also allows for a fast changeover to a new product for the complete forging line, including dies change, leading to higher productivity.

Stamping, forging, upsetting and extrusion products

The Hydraulico STP series is designed and built to meet the highest demands for stability, productivity and flexibility. The range features the newest preforging / upsetting press technologies by Hydraulico, and offers great flexibility and extreme precision required in the aircraft industry.

The two-side forging cylinders are servo-controlled, have a precision greater than + / – 0.1mm and move with a speed of up to 120mm/s.

Hydraulico has previously built a number of customised presses for the extrusion of finned, round or hollow profiles, which can be extruded in steel, titanium or aluminium alloys.
