The large frame-type metal forming hydraulic press is a heavy-duty press-working equipment designed for forming large metal plates, thick plates, shell courses, ring-shaped structural parts, and heavy components. It can be used for processes such as drawing, bending, flanging, cold extrusion, blanking, straightening, and press-fitting of carbon steel, stainless steel, alloy steel, aluminum alloy, and other materials.
For large pressure vessel shell courses, tower shell courses, storage tanks, and heavy cylindrical structural components, forming can be completed through multi-step processes such as pre-bending, segmental pressing, progressive rounding, final rounding, and sizing.
The equipment adopts a high-rigidity heavy-duty frame structure and combines a large-flow hydraulic system with closed-loop control of pressure, position, and speed, meeting the requirements of large-size, high-load, multi-step, and long-cycle continuous operation.
PRODUCT DESCRIPTION
1. High-Rigidity Heavy-Duty Frame Structure
The frame, slide, and worktable are designed for large-scale pressing conditions, with full consideration given to structural strength and rigidity under full-load and off-center load conditions, making the equipment suitable for forming large thick plates and heavy structural parts.
2. Customization from 2,000 T to 10,000 T and Above
Non-standard designs can be provided according to workpiece material, plate thickness, width, yield strength, target diameter, and forming process, matching different tonnages, worktable sizes, openings, and slide strokes.
3. Multi-Step Forming Control
Supports actions such as rapid descent, deceleration approach, pressing, pressure holding, pressure release, and return stroke. Pressure, displacement, speed, speed change points, and pressure-holding time can be set to meet complex processes such as pre-bending, segmental pressing, final rounding, and sizing.
4. Stable Hydraulic Control System
Flow, pressure, and thermal balance are designed according to equipment tonnage and process speed. Proportional or servo control can be configured to achieve continuous adjustment of pressing speed and stable pressure control.
5. Intelligent Control and Data Management
Adopts PLC + HMI control, with optional industrial computer, process recipe management, and pressure-displacement-time curve recording and data export functions. It can also be connected to MES and other production line management systems according to project requirements.
6. Support for Automated Production Line Integration
Can be equipped with heavy-duty conveyor tables, moving worktables, mold changing devices, manipulators, gantry loading/unloading systems, AGV/RGV, and automatic workpiece positioning systems, enabling overall configuration from standalone pressing to automated production lines.
● Pre-bending, segmental bending, and multi-step rounding of large thick steel plates;
● Forming of large shell courses for pressure vessels, towers, storage tanks, etc.;
● Final rounding and sizing of large cylindrical parts, ring parts, and welded shells;

● Manufacturing of energy equipment, petrochemical equipment, pressure vessels, heavy machinery, and large structural parts.
Loading and positioning → Rapid descent → Deceleration approach → Pre-bending/segmental pressing → Pressure holding or displacement holding → Pressure release → Return stroke → Workpiece repositioning → Repeated pressing → Final rounding/sizing → Unloading
For large-diameter, thick-walled cylindrical shells, the target curvature can be gradually obtained through multiple repositioning and segmental pressing operations according to material springback, plate thickness, target diameter, and die structure, improving the consistency of large cylindrical shell forming.
The nominal pressure of the equipment can cover 2,000 T to 10,000 T and above. The number of main cylinders, slide stroke, maximum opening, worktable size, and pressing speed can all be customized according to the project.
The control system supports adjustment, manual, semi-automatic, and automatic operation modes, and can realize multi-stage pressure setting, pressure-holding control, position control, and safety interlocking. According to customer requirements, it can also be equipped with servo hydraulics, synchronous control, process recipes, data acquisition, remote diagnostics, and industrial communication interfaces such as PROFINET, EtherNet/IP, and Modbus TCP.
Large metal forming projects usually do not have completely uniform equipment parameters. We can carry out equipment selection and solution design according to the material grade, plate thickness, plate width, workpiece dimensions, target diameter, forming process, and production cycle time provided by the customer.
From the hydraulic press main machine, hydraulic control, and dies/fixtures to loading/unloading, workpiece positioning, mobile conveying, and automated control, an integrated configuration can be provided according to actual production requirements, offering a complete equipment solution for large metal component forming.
