DENN Rotary Forging Machines (Presses), RF models
Based on the theories of incremental deformation, the DENN Rotary Forging machines, compared with those of traditional forging, require a smaller investment in tools and machinery for its users. Other benefits include better finish, higher precision, and lower energy cost.
FROM THE POINT OF VIEW OF TECHNOLOGY:
– Metal Forming of a larger scale.
– Reduction of forces (5%–20%) due to smaller contact area and less friction.
– Greater dimensional precision (near net shape).
– Optimization of workpiece material dimensions through reduction/elimination of burrs.
– Surface finishing of higher quality thanks to gradual processing and elimination of impact cracks.
– Hardening of the material and optimized grain structure.
– No need for mechanical tooling and welding procedures.
– Technological processes with less noise and contamination (with no environmental impact and sometimes with no grease).
FROM THE POINT OF VIEW OF ECONOMY:
– High flexibility (possibility to obtain new geometries through few modifications).
– Smaller investments due to the reduced size of press.
– Cheaper tooling thanks to the simplified geometry of tools.
– Fewer changes of tools.
– Fewer shaping stages (as compared to the conventional process that usually includes from 2 to 4 stages).
– Lower energy cost.
Typical Applications/ Industries:
Wheel Preforms, Automotive, Agriculture, Aerospace, Space, Defense, etc.
What are our RF rotary forging machine models?
Near-net-shape rotary forging to reduce machining and material waste.
The RF is a rotary forging machine designed to produce parts close to final dimensions using a controlled forging process.
It combines rotary motion and axial compression to gradually form the material, reducing machining requirements and material waste while improving process efficiency.
DENN machines can be integrated into automated production lines.
Benefits of the RF models:
- Higher formation with less effort: Reduced contact area and friction allow forming with 5–20% lower forming forces.
- Near-net-shape precision: Improved dimensional accuracy with reduced or eliminated burrs, minimizing secondary operations.
- Improved material properties: Optimized grain structure, material hardening and enhanced surface finish through gradual forming.
- Process efficiency: Fewer forming stages and lower tooling requirements.
