Available to you from SMS group are state-of-the-art stroke-bound eccentric forging presses featuring our dieformer units. They come complete with automation and rapid-die-changing function, so that our dieformers can be used for practically any forging application: hot and warm forging, and forging with or without flash.
Precision, productivity, faster set-up
Here is a press that gives you the rigidity in both longitudinal and transverse directions ideal for producing precision forgings. That ensures you enhance both productivity and output - thanks to the impressive useful stroke rate and short non-productive times. You also benefit from the rapid-adjustment system for the ram because it makes any necessary corrections during ongoing production - quickly and easily.
To maximize our own efficiency, we developed a modular system based on standardized components. This approach has substantially cut our engineering, production, and erection costs. As a result, you benefit directly from shorter delivery times, lower investment costs, and higher competitiveness because now you can produce forgings at lower cost.
We developed the EP die space to meet today's demands for multiple operations. All the key components are easily accessible for fast maintenance and top availability. There is even a self-supporting machine housing which ensures noise levels far below all current regulations.
What makes our KP wedge presses stand out is their extremely high forging precision. You can also rely on high productivity because the machines apply the full nominal force to several dies in a row.
Way ahead of the competition
Our wedge presses are perfect for forging long parts that demand close thickness and offset tolerances over the whole length. Typical fields of application here are twin con rods, front axles for trucks, crankshafts, balancing shafts, camshafts, and other precision forgings.
Direct-drive screw presses combine massive forming forces with high forging precision. What distinguishes electrically driven screw presses from the flywheel type is that the driven spindle is connected directly to the drive motor - without intermediate gearboxes or other mechanisms.
Intelligent, high-availability machine design
All you have to do is program the forging sequences for your workpieces. You can vary the bottom dead-center position with no need to change the die height.
Furthermore, it's not necessary to adjust the ram as the machine heats up. Power comes from a synchronous motor. Here, the stator is part of the machine frame and the rotor belongs to the flywheel. You also save costs with the braking energy feedback feature.
You'll appreciate our screw presses with continuously revolving flywheel and integral clutch. Why? Because these energy-bound machines give you alternative options no other press type offers you. These presses produce all kinds of forgings. Due to the flexible clutch drive system, the machine type has achieved great success on the market for heat-sensitive materials, e.g. for aircraft and power station components.
Flexible process sequences
Our screw presses apply high forming energy even at reduced ram speed. What makes this possible is our special clutch disengagement technology. Also important are minimum workpiece contact times. Clutch disengagement can be force or stroke-controlled and all functions are controlled electronically.
Forging rolls come into their own when the mass distribution of the preform is already close to that of the required blank. This means you save material costs due to less flash, higher surface qualities from descaling during rolling, and better grain orientation. Furthermore, optimum material distribution and descaling also increase the die service life.
The size of the forging roll depends on the dimensions of the starting material. Generally speaking, you can use material with an edge length of up to 160 mm and a square form for round products with a diameter of roughly 170 mm.
It's easy to integrate our rolls into your existing forging lines. You won't even need extra operating personnel. Plus: high productivity helps you fully utilize the capacity of your downline closed-die forging press. Finally, quick-change systems and the intelligent operating routine ensure short set-up and tooling times.
Stand-out features of our machines for cross rolling are flexibility, high yield, and fast tool changes. We engineered the rolls to prevent scale deposits and asymmetric heating of the rolling dies. There is a special drive principle involving a torque motor and permanently connected shafts. This combines maximum variability with extreme precision. Other options available to you include tool heating and cooling systems.
Do you want to forge mass products such as twin con rods or stub axles for the automotive industry? This is where our cross-rolling machines are ideal for volume distribution. What's more, they substantially optimize the entire process. Why? Because they achieve the best possible blank forms within close dimensional and weight tolerances. Also included in the benefits are reduced flash and die wear. The cross roll precisely finish-rolls rotationally symmetrical parts such as transmission and drive shafts. That often reduces or even eliminates the need for subsequent machining.
