Inclinable C-Frame (OBI) vs Rigid Back Presses: Part Ejection and Production Flow
Gravity: The Cost-Free Parts Feeder
Open Back Inclinable (OBI) power presses feature an adjustable tilting frame that angles backward from $15^circ ext{ to }35^circ$. This simple mechanical feature uses gravity to streamline part ejection in high-speed sheet metal shops.
Comparative Operational Benefits
| Operational Aspect | Inclinable C-Frame Press (OBI) | Rigid Back Fixed C-Frame Press |
|---|---|---|
| Part Ejection | Automatic slide-out through rear chute via gravity | Requires manual pull, air blast, or pick-and-place robot |
| Frame Torsional Rigidity | Slightly lower due to pivot pin mounting | Higher; solid, one-piece floor-bolted feet |
| Die Setup Versatility | Operates upright ($0^circ$) or inclined ($30^circ$) | Fixed vertical orientation ($0^circ$ only) |
| Scrap Evacuation | Falls backward into collection bins automatically | Requires cross-conveyor or beneath-bed scrap shaker |
When to Choose Rigid Over Inclinable
While OBI presses streamline manual blanking, heavy progressive dies and high-tonnage tooling (above $100 ext{ tons}$) call for the solid foundation of a rigid-back fixed press. The absence of pivot points preserves dynamic bed parallelism under maximum cutting loads.
