Fully hydraulic open die forging hammers are designed for powerful, controlled and efficient forging of shafts, rings, flanges, gear blanks and heavy metal components.

Fully Hydraulic Open Die Forging Hammer for Heavy Forging Workshops

A fully hydraulic open die forging hammer is built for workshops that need strong impact energy, fast response and reliable operation in demanding forging conditions. The WM series is suitable for free forging processes where heated billets, ingots or preforms are shaped between open dies using repeated controlled blows.

This machine is commonly used for producing medium and large forgings, including shaft forgings, discs, rings, flanges, gear blanks, blocks, stepped parts and general forged components. It is suitable for carbon steel, alloy steel, stainless steel and other forgeable materials used in industrial production.

Unlike traditional steam or pneumatic systems, the hammer uses hydraulic power to control the striking and return movement. This helps improve operating efficiency, reduce dependence on external air systems and provide smoother control during open die forging work.

Built for Open Die Forging Applications

The WM series hydraulic open die forging hammer is suitable for forging plants, steel processing workshops, heavy machinery manufacturers, tool producers and component suppliers that need flexible forming capacity. It can be used as a standalone forging machine or matched with auxiliary equipment such as forging manipulators, heating furnaces, charging machines and material handling systems.

Typical applications include shaft forging, bar drawing, upsetting, elongating, punching, flattening, ring preforming, flange forging and rough shaping before machining. For higher productivity, the hammer can be integrated into an open die forging line with handling and heating equipment selected according to billet size, material grade and production target.

Pneumatic Forging Hammer Working Principle

The pneumatic power hammer uses a motor-driven flywheel and crank mechanism to operate the internal pneumatic system. As the machine runs, compressed air is directed to move the hammer ram up and down.

The operator controls the forging hammer through the machine control system, usually using a hand lever or foot pedal. This allows the hammer to perform idle running, top positioning, pressing, single blows, light blows and continuous forging blows.

The forging force is created by a combination of ram weight, air pressure and ram speed. This gives the machine strong impact performance while still allowing the operator to control the hammer action during different forging stages.

Key Benefits

Higher Forging Efficiency

Fast striking and controlled hydraulic movement help reduce idle time and improve productivity in open die forging operations.

Better Process Control

Operators can manage stroke, blow action and forging rhythm more effectively, supporting consistent shaping across different forging stages.

Wide Product Flexibility

The hammer can process many forged part types, making it suitable for mixed production workshops and custom forging suppliers.

Reduced External System Dependence

A fully hydraulic design avoids the need for traditional steam systems and can simplify the supporting equipment required for operation.

Suitable for Heavy Materials

The machine is designed for hot forging of forgeable metals including carbon steel, alloy steel and stainless steel.

Strong Workshop Value

The hammer provides a practical balance of impact force, production speed and equipment durability for heavy forging applications.

Process flow

1. Material preparation

Billets, bars or ingots are heated in a furnace to the required forging temperature based on material grade and part size.

2. Workpiece Loading

The heated material is transferred to the hammer area using suitable handling equipment, such as a manipulator, crane or charging system.

3. Initial Forging

The hammer begins rough forming, upsetting, drawing out or flattening the workpiece to prepare the required shape.

4. Controlled Shaping

Repeated hydraulic blows are used to shape the metal between open dies according to the forging plan and operator control.

5. Dimension Correction

The workpiece can be rotated, repositioned and forged again to improve dimensions, section transitions and overall geometry.

6. Final Handling

After forging, the part is transferred for cooling, heat treatment, inspection, machining or the next production stage.
