MiravoHydraulic Press
Discrete-cycle hydraulic press with pneumatic clamping, force monitoring, and hydraulic oil health tracking. 50-100 ton assembly class.
What it is
A press-fit assembly hydraulic press with a deterministic 7-phase cycle: idle ⭢ clamping ⭢ approach ⭢ pressing ⭢ dwell ⭢ return ⭢ unclamp. It adds pneumatic workpiece clamping, ram force and position, and hydraulic oil condition. The model is based on 50-100 ton Beckwood and Greenerd assembly press specifications.

What it tracks
| Member | Description |
|---|---|
press_phase | Current cycle phase, one of 7. |
clamping_demand / clamp_active | Pneumatic clamping state. Interlocked with the air supply. |
clamp_pressure | Pneumatic pressure on the workpiece. |
ram_position | Head travel position in mm. |
ram_speed | Ram velocity, which varies by phase. |
press_force | Applied force during pressing and dwell. |
system_pressure | Hydraulic system pressure. |
oil_temperature | Hydraulic oil thermal state. |
oil_level | Reservoir level. |
good_count / scrap_count / actual_cycle_time | Station throughput and completed-cycle timing, added when the asset is a line station. |
power_draw | Electrical power, which varies by phase. |
Fault modes
seal_leak: system pressure drops ×0.85 and oil temperature rises 8 °C. Production is derated to 0.85.valve_stuck: ram speed and press force drop to zero for 600 s. Production stops.overpressure: a 10 s spike in system pressure and power draw.air_pressure_loss: clamp pressure below 3 bar while clamping; the station stops, and ram speed and force are inhibited for 60 s. It re-arms for as long as the air stays low.pump_failure: end-of-life failure, only in thecriticalstage (rate 2.4/h, so it almost always fires within the stage's 2 operating hours). Ram speed and press force go to 0 and power draw falls to 10 %. Production stops. It has no duration: it stays down untilResetFault,Maintainormiravo inject --clear.
Key parameters
| Parameter | Default | Unit |
|---|---|---|
rated_force_kn | 150 | kN |
stroke_mm | 300 | mm |
cycle_period_s | 12 | s |
motor_power_kw | 7.5 | kW |
Input port
| Port | Default | Unit |
|---|---|---|
supply_air_pressure | 8 | bar |
Shop air header pressure feeding the clamp regulator. The regulator holds clamp_pressure at 5.5 bar until the header sags below 7 bar, then clamp pressure follows it down (1.5 bar regulator drop). Bind it to a compressor header_pressure with inputs: { supply_air_pressure: { asset: <id>, member: header_pressure } }. The Litmus Edge demo templates do this, so a compressor valve_leak stops the press. smart-factory leaves it unbound.
Use cases
- Assembly-line throughput with discrete cycles.
- Cascade fault scenarios: compressed-air loss disables clamping and the press stops.
- Hydraulic oil condition monitoring and predictive maintenance.
- Force-signature analytics for press quality.
