NLS 381 – Downholder with spiral springs for 381

NLS 381:
Downholder (without pressure piece) 
with spiral springs for 381

Ideal to seat, compress or insert workpieces before riveting or forming. A large force range is possible, depending on the chosen spring pack. With coil springs, a very compact but open design is possible. Disk springs offer very high forces, within a closed housing.

  • For low forces
  • To secure the work pieces firmly in the workholder
  • To join or to pretension before the riveting
  • Pretension forces of the hold-down device are client specific, between 0.1 and 0.3 kN possible; must be specified when ordering
  • Flat characteristics
  • Pressure pads are manufactured corresponding to the workholder
  • Note: A retrofit may need replacing the length of the forming tool, the form tool holder and the pressure cup – see
  • Type: NLS-500-381
