The wire-wound hydraulic press represents a new generation of prestressed, ultra-high-pressure forming equipment. It was specifically developed to address critical shortcomings inherent in traditional hydraulic presses—such as structural deformation, fatigue damage, and insufficient pressure stability—that typically arise during prolonged, heavy-load operations.
Utilizing a proprietary wire-wound prestressing technology, this equipment delivers exceptional rigidity, superior pressure stability, and outstanding fatigue resistance. Today, it has emerged as the preferred core forming equipment across high-end manufacturing sectors worldwide, including aerospace, defense, new energy, and precision machinery.
Working Principle of the Wire-Wound Hydraulic Press
The core principle of the wire winding hydraulic press is the “prestressing of offset working stress.” During the manufacturing process, high-strength steel wire is wound in multiple layers and turns around the exterior of the hydraulic press frame under a specific, controlled tension.
Once tensioned, this steel wire exerts a continuous, inward compressive force upon the frame. Conversely, during operation, the internal hydraulic pressure generates an outward-expanding tensile stress. As these two opposing forces effectively counterbalance one another, the overall stress distribution within the equipment becomes significantly more balanced and rational, thereby achieving the following benefits:
- Enhanced frame strength
- Reduced material fatigue
- Minimized deformation
- Improved equipment stability
- Extended service life
Types of Wire-Winding Hydraulic Press
To meet diverse industrial processing demands, our steel wire wound hydraulic presses are classified by structure, tonnage and processing technology.
- Structural Type: C-frame, four-column, eight-column and integral frame types. C-frame and four-column models suit medium and small precision processing. Eight-column and integral frame types are designed for large-table, eccentric load and heavy-duty forming scenarios.
- Tonnage Range: Covers 100T–1000T (small & medium), 1000T–5000T (large), and above 5000T (super-large), supporting up to 10,000-ton ultra-high pressure output.
- Processing Technology: Customized for cold extrusion, hot forging, plate pressing, precision embossing and multi-directional die forging.
Core Technological Advantages
1. Pre-stress Balancing Technology: More Stable Pressure Output
Through precise tension calculations and a multi-layer winding process, we achieve a precise match between the pre-stress of the machine frame and the hydraulic cylinders. Under ultra-high pressure conditions, pressure remains undiminished and free of fluctuations, ensuring a uniform and stable output. This technology is perfectly suited for heavy-load, high-precision forming processes.
2. High Rigidity & Low Deformation: Superior Forming Precision
The entire machine features a uniform stress distribution, offering exceptional resistance to deformation and off-center loading. Under high-pressure operating conditions, the micro-deformation of the machine body remains fully controllable. This results in workpieces with high dimensional accuracy and excellent consistency.
3. Weld-Stress-Free Technology: Enduring Machine Stability
The core frame structure is free of large-area welding joints. This completely eliminates issues related to residual welding stress, as well as long-term deformation and aging associated with welded structures. The equipment’s precision remains constant over time, requiring no frequent calibration or adjustment. It is ideally suited for long-term, large-scale mass production.
4. Customized Adaptability: Multi-Purpose Functionality
Based on workpiece dimensions, process requirements, and load characteristics, we can customize the winding layers, machine frame structure, pressure parameters, and worktable specifications. The system is compatible with a wide range of processes, including metal cold and hot extrusion, sheet metal pressing, precision coining, and composite material molding. This ensures exceptional versatility and adaptability across various applications.
Main Application Scenarios
With high pressure, high precision and long service life, the equipment is widely applied in global high-precision manufacturing fields.
