Crank / eccentric press

Machines

Scope and limits

Crank / eccentric press: Capability screening from explicit operating inputs and machine limits. Flat punch, simultaneous cutting perimeter, cutting force only. Additional stripping/blank-holder forces and load curves need separate evidence. Not assessed: Force/stroke curve and flywheel recovery.

Standards and references

ISO 16092-1:2017

General press safety

Source scope
Cold-metal presses; excludes press brakes/folders, turret punches, single-purpose profile punches and tube benders.
Implementation in Prufi
Public scope/reference only; no licensed tolerance tables, safety tests or automatic machine capacity values. Manufacturer equations require explicit operating inputs and confirmation.

DIN EN ISO 16092-2:2021-04

Mechanical press safety

Source scope
Part-revolution clutch and mechanical servo presses within ISO 16092-1 scope.
Implementation in Prufi
Public scope/reference only; no licensed tolerance tables, safety tests or automatic machine capacity values. Manufacturer equations require explicit operating inputs and confirmation.

Punch capacity: 72 kN / 80 kN

Declared machine scenario

The 40 × 60 × 2 mm plate is stock, not a finished pierced part. A declared 100 mm simultaneous cutting perimeter and Rm = 400 MPa give 72 kN; compare with the displayed press limit.

Dimensions (approx.): 40 × 60 × 2 mm

Scenario inputs

Synthetic machine and operation data. These values cannot be inferred from the shape alone.

Expected check result

MAC-001.CUTTING_FORCE: expect an explicitly passed capacity check; other requirements remain unassessed.
