A hydraulic free forging press is a fully hydraulically controlled forging machine that utilizes liquid pressure to transmit energy. Its most significant feature is that the workpiece is not constrained by a fixed die during the forging process, but rather is freely deformed by upper and lower anvils and operating tools, resulting in a high degree of process flexibility.

This hydraulic free forging machine is primarily used for forging alloy steel, stainless steel, high-alloy steel, and non-ferrous metals. It can perform various functions, including rapid forging, constant forging, and pressure-holding. It meets the requirements of forging processes such as upsetting, drawing, punching, reaming with a spur, and offsetting. It is suitable for the mass production of forgings. PDH can design and customize four-column and frame-type configurations according to specific requirements. Available tonnages include 2,500, 3,000, 4,000, 5,000, 6,300, and 8,000 tons.

What is Free Forging?

Free forging is a process in which a heated metal billet is placed between upper and lower forging irons in a forging machine. Impact or pressure is applied to the billet, directly causing plastic deformation to form the desired forged part. Free forging, due to its simple shape and flexible operation, is suitable for the production of single pieces, small batches, and heavy forgings.

Features of the Free Forging Hydraulic Press

1. The machine utilizes a prestressed composite frame structure, ensuring stability and reliability, and a long service life.
2. The slide guide utilizes a 16-way adjustable guide rail, ensuring high precision and strong resistance to side loads.
3. Incorporating the principles of a high-speed forging hydraulic press, it is equipped with a high-response proportional cartridge valve and a rapid unloading system. This enables high forging frequency, significantly improving customer production efficiency.
4. It utilizes specialized multi-stage pressure relief technology for rapid pressure relief, eliminating pressure relief shock at high flow rates and providing technical support for rapid forging.
5. It can be configured with supporting production line equipment, including a forging manipulator, loader/unloader, heating furnace, feeder trolley, rotary material table, and anvil magazine.

Applications of Free-Forging Hydraulic Presses

Due to their flexible processing characteristics and powerful forming capabilities, free-form forging presses are widely used in the manufacturing of various large forgings and key components:

1. Energy and Power Industry

• Manufacturing core components such as turbine main shafts, steam turbine rotors, generator rotor shafts, and large generator bearing seats.
• Forged parts exhibit increased structural density and fatigue strength, meeting the demands of high speeds and high loads.

2. Metallurgy and Heavy Machinery Industry

• Manufacturing large forgings such as rolling mill rollers, gears, eccentrics, crankshafts, and connecting rods.
• Free-form forging can process materials such as alloy steels and high-strength alloys, ensuring the mechanical properties of complex parts.

3. Shipbuilding

• Forging key components such as marine crankshafts, propeller shafts, large gear rings, and rudder stocks.
• Multi-pass free forging enhances corrosion and impact resistance, ensuring long-term stable operation of ships in harsh sea conditions.

4. Aerospace

• Widely used in forging high-performance components such as aircraft engine turbine discs, landing gear struts, rocket engine nozzles, and load-bearing rings. Open die forging can effectively improve metal grain flow distribution, enhance component strength and reliability, and meet the requirements of extreme operating conditions.

5. Petrochemical and Pressure Vessel Industries

• Manufacturing large flanges, cylinders, nozzle sockets, sealing rings, and other products.
• It is particularly suitable for components subjected to high-pressure, high-temperature, and highly corrosive environments, ensuring the long-term safe operation of equipment.

6. Transportation and Rail Engineering

• It is suitable for the production of key components such as high-speed train axles, subway axles, and large automotive gears.
• Fress forgings significantly improve impact toughness and wear resistance, extending service life.
