A multi-directional forging hydraulic press is a type of hot forging hydraulic press. The main machine consists of an upper beam, guide columns, a worktable, a movable crossbeam, a main cylinder, an ejector cylinder, a horizontal beam, and a horizontal cylinder. A pressure-maintaining circuit is incorporated into the hydraulic system. This maintains pressure to ensure stable workpiece forming. To prevent hydraulic shock, a pressure relief circuit is incorporated into the system, ensuring safe and stable operation. Currently, PDH manufactures multi-directional forging hydraulic presses in various tonnages, including 500, 630, 800, 1,000, 1,250, 2,000, 2,500, 3,000, 3,500, 4,000, and 5,000 tons.

Working Principle of a Multi-Directional Hydraulic Forging Press

A multi-directional hydraulic forging press primarily utilises hydraulic pressure to drive multiple rams arranged perpendicularly, which act simultaneously or alternately on the workpiece. Because the blank is subjected to three-dimensional compression, internal deformation is more uniform and metal fluidity is enhanced, thereby improving structural properties and increasing material utilisation.

Features of the Multi-directional Forging Hydraulic Press

1. The multi-directional forging hydraulic press body adopts a frame structure, offering excellent rigidity, high precision, and strong resistance to off-center loads.
2. A stretching slide and blank holder slide are installed on the rear horizontal side. This allows for simultaneous forming in four horizontal directions (four axes). The rear direction features dual-action pressing, providing high efficiency. Frame structure
3. An online inspection system employs image detection technology to assist in the development of an extrusion forming process system, enabling flexible forming and real-time correction of multi-directional die forgings.
4. High-performance PLC control technology is employed to control the feeding, retrieving, and positioning mechanisms of multi-directional die forgings, as well as the cooling and lubrication of multi-directional die forgings, extrusion depth, extrusion pressure, and blank holder force. Hydraulic servo control and multi-axis motion control are also available.
5. A dedicated hydraulic proportional servo system enables proportional pressure regulation and variable pressure control.
6. Equipped with automatic loading, unloading, and retrieving devices for multi-directional die forgings, this effectively reduces labour costs. 7. The bottom beam is equipped with a hydraulic pad. Through the operation panel, the hydraulic pad can realize three working cycles: with ejection, without ejection and hydraulic pad edge pressing.

Advantages of the PDH Multi-directional Hydraulic Forging Press:

1. The PDH multi-directional hydraulic forging press produces low vibration and noise, which is not disturbing to residents and meets environmental protection requirements.
2. High efficiency. Especially during upsetting, the efficiency is many times higher than that of a forging hammer.
3. Low price. Forging presses of equivalent capacity are significantly cheaper than forging hammers (for example, an 800-ton hydraulic forging press is over ¥500,000 cheaper than a 5-ton hammer).
4. Low foundation cost. Compared to forging hammers, the foundation cost is more than half that of a forging hammer, and the factory building does not require vibration isolation.
5. Forged workpieces exhibit excellent internal and external uniformity, reliable quality, and few defects.

Applications of Multi-Directional Forging Hydraulic Presses

The main uses of multi-directional forging hydraulic presses can be summarized as follows:

1. Forging high-performance, difficult-to-deform alloys

• Particularly suitable for materials difficult to form using traditional processes, such as titanium alloys, high-temperature alloys, and stainless steel.
• Multi-directional force application promotes full plastic flow of the metal, preventing internal defects.

2. Manufacturing large, integral components

• Suitable for the production of aerospace engine integral blades, turbine disks, large bearings, rotors, and key nuclear power components.
• Maintaining part integrity while improving strength and toughness.

3. Forming complex, precision parts

• Forming complex shapes or asymmetric structures using multi-directional extrusion, reducing machining allowances.
• Increasing material utilization and reducing costs.

4. Improving microstructure and performance

• Eliminating defects such as shrinkage cavities and segregation through three-dimensional stress state forging.
• Making the microstructure denser and more uniform, achieving excellent mechanical properties.

5. Military and high-end equipment manufacturing

Widely used in the manufacture of key load-bearing components in aviation, aerospace, shipbuilding, weapons, energy, and other fields.

In short, multi-directional forging hydraulic presses are primarily used to manufacture high-performance, densified, defect-free, and difficult-to-deform alloy parts, especially key components in the aerospace and energy industries.
