Application to cold and hot forging using servo press

Introduction to Servo Press Technology

Servo press technology has completely transformed the forging industry by enabling precise control and flexibility.
It has opened a new era for cold and hot forging applications, where precision and efficiency are critical.
In this article, we will explore how servo presses are applied in both cold and hot forging processes, and the advantages they bring to the table.

Understanding Forging Processes

Before diving into the application of servo presses in these processes, it’s essential to understand what forging is.
Forging is a manufacturing process involving the shaping of metal using localized compressive forces.
Typically, it’s classified into two types – cold forging and hot forging.

Cold Forging

Cold forging is carried out at or near room temperature.
It’s known for offering superior dimensional accuracy and surface finish.
Components made through cold forging require less or no machining post-process.
However, the materials used need to have excellent ductility to withstand shaping without cracking.

Hot Forging

In hot forging, metal is heated to a temperature where it becomes more pliable, making it easier to shape.
This process reduces the risk of cracking and improves mechanical properties like toughness and ductility.
Hot forging is typically used for creating larger parts or components that require substantial deformation.

The Role of Servo Presses in Forging

Servo presses have become an integral part of the forging industry thanks to their precision, flexibility, and efficiency.

What is a Servo Press?

A servo press is a type of mechanical press driven by a servomotor.
Unlike traditional mechanical presses that use a flywheel for energy, servo presses use a servomotor to control the ram’s motion directly.
This allows for precise control over the position, speed, and force during operation.

Applications of Servo Presses in Cold Forging

Servo presses have significantly enhanced the cold forging process.

Precision and Accuracy

Servo presses ensure superior precision and accuracy in cold forging.
By allowing precise control over the ram’s motion, parts are created with exact dimensions, reducing the need for additional machining.

Flexible Motion Profiles

With programmable motion profiles, servo presses can adapt to various cold forging tasks.
This flexibility enables complex part geometries to be achieved without compromising cycle times.

Energy Efficiency

Servo press technology is known for its energy efficiency.
The ability to control the speed and force applied reduces the energy consumption significantly compared to traditional forging methods.

Applications of Servo Presses in Hot Forging

Servo presses are equally beneficial in the hot forging process.

Improved Material Flow

In hot forging, controlling material flow is critical.
Servo presses give operators control over the forming speed and force, providing consistent material flow and excellent part integrity.

Enhanced Temperatures Tolerance

Servo presses are designed to handle high temperatures, crucial for hot forging processes.
This capability ensures that no loss in quality occurs due to temperature variations in the metal.

Reduced Tool Wear

The ability to control every aspect of the press operation helps in reducing tool wear.
This not only extends the lifespan of the tools but also lowers overall operation costs.

Advantages of Using Servo Presses

Using servo presses in forging processes comes with several advantages that make them invaluable.

Increased Production Rates

Servo presses can operate at higher speeds without compromising precision or quality, leading to increased production rates.

Lower Maintenance Costs

The precision and control offered by servo presses reduce wear and tear on tools and equipment, leading to lower maintenance costs and longer machine lifespans.

Enhanced Safety

With better control, servo presses improve the safety of forging operations.
The programmable motion allows for more secure handling of materials and reduces the risks associated with high-speed operations.

Conclusion

The application of servo presses in cold and hot forging processes represents a significant advancement in the manufacturing industry.
With their precision, flexibility, and efficiency, servo presses enhance production quality while reducing costs and energy consumption.
As the forging industry continues to evolve, integrating servo press technology will remain critical for operations looking to stay competitive and meet the complex demands of modern manufacturing.
