Applications of Frame-Type Hydraulic Presses in the Aerospace Industry

Compared to automotive manufacturing, the application of frame-type hydraulic presses in the aerospace sector focuses more on overcoming manufacturing challenges associated with hard-to-deform materials, large integral structural components, and precision thin-walled parts. Their high rigidity and precise control capabilities are crucial for processing aerospace materials such as titanium alloys and superalloys. The following insights are provided by the team at Jianlong Hydraulic Technology; please feel free to contact us for more information.

1. Core Application Scenarios

1.1 Large-Scale Precision Die Forging and Multi-Directional Die Forging

This is the primary application of frame-type hydraulic presses in the aerospace field. Utilizing multi-directional die forging technology, the equipment can apply simultaneous pressure to the workpiece from multiple vertical and horizontal directions. This enables the single-step forming of large, complex precision aerospace forgings—such as engine blades, landing gear components, and titanium alloy rings—while significantly enhancing forging density and mechanical properties. Notably, the world's highest-tonnage press—a 1,250 MN (125,000-ton) multi-directional die forging hydraulic press—was developed specifically to resolve critical manufacturing bottlenecks regarding large and ultra-large aerospace components.

1.2 Forming of Hard-to-Deform Materials (e.g., Titanium Alloys)

The aerospace industry makes extensive use of titanium alloys and superalloys. Thanks to high-precision pressure/displacement control and constant strain-rate forging modes, frame-type hydraulic presses can effectively manage the deformation process of these sensitive materials, preventing cracking and meeting strict precision requirements. For instance, 2,000-ton frame presses are used to process thin-walled titanium alloy parts, while 5,000-ton frame-type multi-directional hot die forging presses are specifically designed to tackle the forming challenges of complex components like aero-engine blades.

1.3 Large Thin-Walled Sheet Metal and Skin Parts

For irregularly shaped sheet metal parts with stiffeners (commonly known as "corrugated panels"), frame-type hydraulic presses can employ the rubber-diaphragm hydraulic forming process. By applying a pre-forming pressure of 8–10 MPa followed by a final forming pressure of 20 MPa, the part is made to conform perfectly to the mold. This method replaces traditional explosive forming, thereby resolving issues related to long production cycles, inconsistent quality, and harsh working environments. 1.4 Compression Molding of Composite Components

As the use of composite materials in aircraft increases, frame-type hydraulic presses are employed for the compression molding of thermoset and thermoplastic composites (such as SMC and GMT) to manufacture secondary structural components or interior parts. The high stability of the frame structure ensures the precision of the finished products.

2. Other Related Forging Applications

In addition to the core applications mentioned above, frame-type hydraulic presses (or related high-speed forging hydraulic units) are utilized in the open-die forging of aerospace components. Processes include cogging, upsetting, and drawing out of superalloys and specialty stainless steels, thereby producing suitable billets for subsequent precision closed-die forging.

In summary, within the aerospace sector, frame-type hydraulic presses are not merely powerful forming machines; they are critical equipment for addressing two major challenges: the difficulty of processing certain materials and the need for structural integration.
