Single Point vs Two-Point Crank Power Presses: Resolving Tipping Moments in Wide Beds
Handling Off-Center Loads on Extended Beds
When stamping components across a wide progressive strip, load forces rarely concentrate directly underneath the center of the slide. Single connection point rams tilt when subjected to off-center loads, causing uneven die penetration.
Suspension Comparison Table
| Operating Metric | Single-Point Crank (MDC-1) | Two-Point Crank (MDC-2 Series) |
|---|---|---|
| Slide Support Points | 1 central pitman connecting screw | 2 synchronized connecting rods spaced apart |
| Resistance to Die Tipping | Limited; susceptible to side moments | High; dual pitmans balance eccentric forces |
| Max Recommended Bed Width | Up to 800 mm | 1,200 mm to 2,500+ mm |
| Application Suitability | Single-station blanking & piercing | Automotive structural channels, progressive brackets |
Synchronized Crank Eccentrics for Parallel Movement
Milap Two-Point Crank presses utilize dual, ground eccentric gears timed together to drive both pitmans in unison. Even if the blanking station on the left generates $180 ext{ tons}$ while the right station generates only $30 ext{ tons}$, the slide face remains parallel within microns.
