Applications of Frame-Type Hydraulic Presses in Automotive Manufacturing

Frame-type hydraulic presses are primarily utilized in automotive manufacturing for the stamping of large body panels, forging of critical structural components, composite material molding, and precision part forming. Their high rigidity and resistance to off-center loads make them ideal for production stages requiring exceptional precision and stability. The following overview is provided by Jianlong Hydraulic Technology; please feel free to contact us for further inquiries.

1. Body Panels and Sheet Metal Stamping

This is the most fundamental application for frame-type hydraulic presses. They are suitable for the stamping and deep drawing of components such as car doors, body structures, axle housings, and chassis parts, as well as for forming large automotive body panels. The rigidity inherent in the frame structure ensures uniform force distribution during the sheet metal drawing process, thereby minimizing springback and cracking.

2. Critical Forgings for Chassis and Powertrain Systems

In the automotive forging sector, frame-type hydraulic presses are primarily used for hot forging processes to manufacture high-strength chassis and powertrain components.

2.1 Specific Components: Includes steering knuckles, axle shafts, connecting rods, universal joint yokes, control arms, and gear blanks.

2.2 Tonnage Selection: Small-to-medium-sized, simple forgings (e.g., connecting rods, flanges) typically utilize 1,000-ton models, whereas large, complex forgings (e.g., steering knuckles, axle shafts) require equipment with a capacity of 1,600 tons or higher.

2.3 Process Advantages: The resistance to off-center loads provided by the integral frame structure ensures stable force application on red-hot metal billets during die forging, thereby enhancing forging precision and extending die service life.

3. Molding of Composite Materials and Lightweight Components

Driven by the trend toward automotive lightweighting, frame-type hydraulic presses play a pivotal role in composite material forming, particularly for molding processes involving materials such as SMC (Sheet Molding Compound).

3.1 Typical Products: SMC automotive front bumpers, air deflectors, body panels, and other exterior components. Manufacturers have successfully utilized 2,000-ton class Frame hydraulic presses to mold bumpers in a single operation. 

3.2 Process Characteristics: The multi-cylinder frame design ensures uniform pressure across large work surfaces, meeting the requirements for integrated hot-press molding, curing, and demolding operations, thereby enhancing production continuity and product consistency.

4. Precision Component Forming and Press-Fitting

Servo-controlled CNC frame-type fine-blanking hydraulic presses offer high-precision solutions for small, precision automotive components.

4.1 Applicable Parts: Includes seat adjustment gear plates, seatbelt buckles, brake shoes, exhaust flanges, seat recliners, etc.

4.2 Process Scope: Covers precision stamping, assembly, coining, punching, and trimming; suitable for safety-critical and functional components requiring high precision and consistency.

5. Specific Vehicle Models and Components

5.1 Automotive Chassis Beams: Specialized frame-type hydraulic presses designed for forming long components; they offer superior precision and synchronization compared to traditional setups using multiple four-column presses, increasing production efficiency by 1 to 3 times.

5.2 Aluminum Alloy Wheels: Horizontal pre-tensioned plate-Frame hydraulic presses are ideal for forming aluminum alloy wheels, combining a compact structure with high load-bearing capacity.

In summary, the role of frame-type hydraulic presses in automotive manufacturing is evolving from general sheet metal forming toward large-scale, high-precision, and lightweight applications, covering critical manufacturing stages from vehicle body shells to core powertrain and chassis components.
