Applications of Multi-directional Forging Hydraulic Presses in the Aerospace Industry

Multi-directional forging hydraulic presses are core equipment in the aerospace industry for manufacturing critical load-bearing components, often referred to as the "forging platform for major national equipment." By applying pressure simultaneously from multiple vertical and horizontal directions, they can form complex precision forgings in a single operation, significantly improving material utilization and the overall performance of the parts. Below, Jianlong Hydraulic Technology shares its specific applications, core advantages, and latest developments in the aerospace field.

1. Typical Application Parts

Multi-directional forging hydraulic presses are mainly used to manufacture critical components in aircraft and spacecraft that experience the most demanding stresses and have the highest safety requirements:

1.1 Aircraft Structural Components

• Landing gear, wing spars, fuselage structural components.

• Bearing the enormous alternating loads during takeoff, landing, and flight, requiring extremely high strength and fatigue resistance.

1.2 Engine Core Components

• Turbine disks, engine blades, disk-shaft assemblies, engine casings.

• Operating under extreme conditions of high temperature, high pressure, and high speed, requiring excellent high-temperature resistance and creep resistance.

1.3 Key Helicopter Components

• Rotor System Structural Components

• Core lift and control components of helicopters, requiring stringent reliability and shock resistance.

1.4 Spacecraft Components

• Rocket Shells, Missile Nozzles, Torpedo Shells

• Require extremely high structural strength and lightweight design to meet carrying and flight performance requirements.

2. Technological Advantages

Compared to traditional forging processes, multi-directional forging has irreplaceable advantages in manufacturing aerospace parts:

2.1 Integral Forming, Stronger Parts

Complex structures originally composed of multiple welded or assembled parts (such as flanged valve bodies or landing gear with internal cavities) can be forged as a single integral piece, eliminating the weak link of weld seams, resulting in complete and continuous metal flow lines, and significantly improving fatigue and stress corrosion resistance.

2.2 High Material Utilization, More Economical Manufacturing

Aerospace widely uses expensive materials such as titanium alloys and high-temperature alloys. As a flashless closed-die forging process, multi-directional forging can increase material utilization by 20%-50% compared to traditional processes, significantly reducing costs. 2.3 Precision Forming, Simplified Subsequent Processing

It can directly forge complex shapes close to the finished product size, even including structures such as deep holes and grooves, significantly reducing subsequent machining and preserving the complete metal flow lines.

2.4 Controllable Performance, More Stable Quality

Advanced isothermal forging and multi-directional forging technologies enable forming under precisely controlled temperature and pressure, ensuring uniform internal structure and stable performance of the forgings, meeting the extremely high consistency requirements of parts such as aero-engine blades.

3. Latest Developments and Major Equipment

To meet the needs of major projects such as China's domestically produced large aircraft and next-generation aero-engines, China is moving towards a world-leading level in the field of multi-directional forging. The world's largest 1250MN (125,000 tons) multi-directional forging hydraulic press has started construction in China and entered the main installation phase. This equipment adopts cutting-edge technologies such as prestressed wire winding and ultra-high pressure, possessing both ordinary forging and multi-directional precision forging capabilities, and achieving precise control of forging speed. Furthermore, Jianlong Hydraulic Technology has also achieved breakthroughs in supporting technologies such as isothermal precision forging dies and specialized temperature-controlled die holders, breaking the monopoly and significantly improving the manufacturing quality and die life of components such as aerospace blades. It has become a rising star in this field and the preferred choice for many customers.

In summary, multi-directional forging hydraulic presses are key equipment for achieving "high precision, high performance, and low cost" manufacturing in the aerospace industry. With the completion of the world's largest multi-directional forging hydraulic press, China's support capabilities in high-end manufacturing will achieve a historic leap.
