Radial forging machines

Forging - Pressing processes

Our strengths - your edge

It's easy to sum up the demands of the forging industry: high precision and productivity, perfect microstructure, plus flexible application, batch size, and unit production. This is where we not only meet today's requirements, but also ensure your competitive edge in the future. What puts our hydraulic radial forging machines at the top of the global tree is this: their innovative design, high performance, and intelligent technology.

Concepts

Radial forging machine

SMX hydraulic radial forging machines

Our SMX hydraulic radial forging machines deliver precision and productivity, perfect microstructure properties, plus flexibility of application, batch size, and single-item production.

SMI hydraulic forging machines

SMI is an automatically controlled and hydraulically driven 2-ram forging machine with integrated manipulators and centering devices for automatic operation. It is ideal for the mass distribution of hot forgings used for the closed-die forging. It is capable of forging all materials that are normally forged using open-die forging equipment.

Manipulators

Our manipulators for forging machines are particularly robust. Why? Because they offer you not only high load-bearing capacity, but also precise interaction between the manipulators and the forging machine. That's crucial for a perfect forging result.

The manipulators move in sync with the machine - for a fast and smooth forging process. They come with hydraulically driven tongs. We specially designed the tong peel as a hollow shaft so you can also use a mandrel forging device, e.g. for tubes.

Technology

Innovative hydraulic cylinders

Maximum performance with stroke sequences

These virtually maintenance-free press cylinders incorporate our patented technology. Here is the basic principle: a servo-controlled pilot cylinder is followed by the working piston. This pilot cylinder controls the forming rate and return stroke. That means you achieve pinpoint accuracy - every time.

Your benefits at a glance

Vibration-free operation, low noise
Up to 300 strokes/min. (depending on machine size)
Extremely long maintenance intervals

COMFORGE^®

Intelligent technology package

What ComForge^® does for you is precisely calculate your pass schedules. It takes into account everything from cross-sectional shape to forging process as well as your specific requirements (e.g. fine grain structure). The intuitive user interface makes it easy to input all parameters:

Geometry of the initial and final dimensions
Material quality of the forging
Tool and machine parameters
Deformation parameters
Furnace temperature

Forging railroad axles

How to save energy and time

Using our SMX hydraulic radial forging machine, you can forge up to three axles from a single ingot in just one heat. This means no process interruption for intermediate heating. That not only boosts productivity, but also cuts energy consumption. The hydraulic radial forging machines with fully synchronized manipulators forge the workpieces through to the core over the whole length. Simultaneous loading and unloading ensure a faster process and higher output. Here is how: as the forged ingot is removed on the unloading side, a new ingot is already clamped onto the loading side.

Forging thick-walled tubes

High straightness, minimum eccentricity

To help you boost your business, SMS group modified and extended its proven SMX concept to include tube forging. Specifically, we expanded the plant layout to incorporate a third manipulator that holds a mandrel bar. Also integrated are conically shaped tools that ensure high-quality tube surface finishes. The infeed movement and the turn angle of the manipulator are designed for an optimum material flow. The tube forging process consists of a single pass. Even if you process extremely eccentric mother tubes, you still produce finished tubes with low eccentricity and high straightness.
