Technical Specifications for Frame-Type Hydraulic Presses

The technical specifications for frame-type hydraulic presses are not fixed values; instead, they form a series of products based on nominal force, structural design, and specific process requirements—varying in core parameters such as nominal force, slide stroke, daylight (opening height), and table dimensions. The following information is provided by the team at Jianlong Hydraulic Technology; please feel free to contact us with inquiries.

1. Reference for Core Selection Parameters

Parameters vary significantly across models of different tonnages. The following comparison of typical specifications is provided for your reference during procurement:

Frame-type hydraulic presses cover a wide range of nominal forces; common series include 200t, 315t, 400t, 500t, 630t, 800t, 1000t, 1200t, 2000t, and 2500t. For heavy-duty forging or the forming of extra-large components, Jianlong Hydraulic Technology offers specifications ranging from 800t to 4000t, with system pressures typically designed around 25 MPa. Specialized frame-type presses—featuring centering and punching devices—are also available for processes such as open-die forging and ring piercing; parameters like daylight and moving table dimensions are significantly adjusted to suit these specific processes.

2. Key System Configurations

In addition to mechanical parameters, the control and hydraulic systems are crucial components of the specifications:

2.1 Electrical Control: Mainstream models generally utilize PLCs (Programmable Logic Controllers) for control, supporting adjustment, manual, and semi-automatic operation modes to achieve constant-pressure or constant-stroke processes.

2.2 Hydraulic System: Typically includes integrated cartridge valves, a high-pressure pump station, and cooling/filtration systems. High-tonnage equipment is equipped with automatic protection devices, such as multi-stage overload protection and alarms for oil temperature and oil level.

3. Structural Characteristics of the Frame Design

3.1 High-Rigidity Monoblock Frame

The machine body features a frame-type structure offering high overall rigidity and resistance to deformation, making it suitable for processes such as stamping, press-fitting, forming, deep drawing, bending, and straightening. 3.2 High Resistance to Off-Center Loads

The frame-style structure, combined with a high-precision guiding system, effectively minimizes operational errors caused by off-center loading on the slide. This makes it particularly suitable for large workpieces and molds.

3.3 High Operational Precision

Precision machining and assembly of the frame, bolster, slide, and guide rails ensure superior parallelism, perpendicularity, and repeatability.

3.4 Adjustable Pressure and Stroke

Operating parameters—such as working pressure, slide stroke, dwell time, and speed—can be configured to meet specific process requirements, enabling control modes like constant-pressure or constant-stroke operation.

3.5 High Level of Automation

The system supports the integration of PLCs, touchscreens, displacement and pressure sensors, robotic arms, automatic loading/unloading systems, and moving bolsters to facilitate automated production.

4. Selection Recommendations

When selecting specifications, prioritize the following three core parameters:

4.1 Nominal Force: Must exceed the maximum forming force required for the workpiece.

4.2 Slide Stroke and Daylight (Opening Height): Must accommodate the workpiece dimensions (daylight) and allow for the full pressing cycle (slide stroke).

4.3 Bolster Dimensions: Must accommodate the projected area of the mold and workpiece.
