A large-tonnage hydraulic press developed for large-scale, heavy-duty pressing and forming processes. The press adopts a prestressed steel wire-wound load-bearing structure. By pre-tensioning high-strength steel wires, the frame is placed under proper compressive stress and works together with the main frame to bear the pressing load, thereby improving the stress state, reducing local stress concentration, and enhancing frame rigidity, fatigue resistance, and long-term operational stability.
The nominal pressure range covers 5,000 T / 8,000 T / 10,000 T / 15,000 T / 20,000 T. Customized/non-standard designs can be provided according to product, die, and process requirements.
PRODUCT DESCRIPTION
1. Prestressed Steel Wire-Wound Structure
High-strength steel wires are pre-tensioned to form a prestressed load-bearing structure, improving the stress state of the main body under ultra-high load conditions and enhancing overall load-bearing capacity and fatigue resistance.
2. High-Rigidity Main Body Design
The frame, moving crossbeam and worktable are analyzed for strength, rigidity and deformation for large-scale equipment, ensuring structural stability under high-load conditions.
3. Multi-Cylinder Synchronous Control
For equipment with large worktables, a multi-main-cylinder structure can be adopted, equipped with multi-point displacement detection and synchronous control, improving operational stability under eccentric load conditions.
4. Coordinated Control of Pressure, Speed and Position
The electro-hydraulic servo system performs closed-loop adjustment of pressure, displacement, speed and holding time, meeting the requirements of complex pressing processes.
5. Multi-Stage Pressing Process
Supports pre-pressing, staged pressure increase, constant-pressure holding and staged pressure release, suitable for products with clear requirements on the pressing curve.
6. Process Data Traceability
Can record pressure-time, displacement-time and pressure-displacement curves, as well as holding time, product recipe, alarm information and product batch data.
Pressing and forming of large metal structural parts, pressing of thick plates and large plates, shape correction of cylinders and ring-shaped parts, high-pressure forming of powder materials, compression molding of composite materials, compression molding of polymer materials, pressing and mold closing of large molds, press-fitting of large components, high-pressure forming of special materials, etc.
The equipment mainly consists of a steel wire-wound frame, main working cylinder, moving crossbeam, worktable, hydraulic power system, electrical control system and safety protection system. The main cylinder can be of single-cylinder, multi-cylinder or combined structure; the worktable can be fixed, movable or floating, and can be equipped with ejection, mold clamping, positioning and automatic mold changing systems.
