Why has the four-column hydraulic press become the mainstream choice for metal forming? Detailed explanation of the core advantages

1. Structural stability and high-precision processing capabilities
Rigid frame design: The four-column hydraulic press adopts a three-beam four-column or four-beam four-column structure, which is composed of a high-strength alloy steel column and an upper and lower beam to form a closed frame. It has strong anti-eccentric load resistance, can effectively disperse pressure, avoid deformation, and ensure processing accuracy.
High guiding accuracy: The four-column guide is combined with a precision guide sleeve, which is particularly suitable for asymmetric workpiece processing, reducing the impact of lateral force and extending the life of the mold.
Large tonnage carrying capacity: Hydraulic transmission can achieve ultra-large working pressure and long stroke, which is suitable for the forming of large or complex workpieces.

2. Process flexibility and production efficiency
Multi-stage pressure and speed control: The hydraulic system supports multi-stage speed adjustment such as fast down, slow pressure, pressure holding, and pressure relief to meet the process requirements of different materials (such as aluminum alloy and stainless steel) and avoid damage to the workpiece.
Simplify the production process: Compared with the stamping process, hydraulic forming only needs one set of molds to complete complex parts (such as automobile radiator brackets), reducing mold costs by 20%-30%, and reducing the amount of subsequent welding and machining.
Pressure holding and stability: The maximum pressure can be maintained at any position in the stroke, and the pressure can be maintained for a long time to ensure the molding quality, especially suitable for precision parts (such as thin plate stretching).

3. Product features and advantages
The operating force, no-load walking, low-speed movement and stroke range can be adjusted according to the process requirements.
Computer optimized design, three-beam four-column structure, simple and cost-effective.
The hydraulic control system adopts the integrated cartridge valve, which is reliable and durable, with small hydraulic impact, short connecting pipeline and few pressure relief points.
Independent electrical control, reliable, intuitive and easy to maintain.
The centralized button control system can choose adjustment, manual and semi-automatic operation modes.
The fixed-stroke molding process or fixed-pressure molding process can be selected through the control panel, with pressure holding and delay functions.
