Flexible
Clamp System

EVK with ZSF

  • For medium and large presses
  • For various die dimensions
  • For clamping upper dies
  • For dies with U-recesses and standardised clamping dimensions
  • Suitable for retrofitting

Mode of operation

  • The electric positioning unit moves the spring clamp unit along the T-slot.
  • A single-acting spring clamp cylinder generates the clamping force.
  • Unclamping of the spring clamp units is effected hydraulically.

Description

The electric positioning unit moves the spring clamp unit by means of a chain. For clamping, the clamp unit is depressurized so that the springs generate the clamping force. Hydraulic pressure is required for unclamping and for positioning of the clamp units. Therefore, pressure control by means of a pressure switch on the hydraulic power pack is necessary. The electric positioning units may be switched off individually by the machine control so that these clamp units remain in their park position, where they are clamped.

1)  Mechanical damage may occur at higher load.

Fixing is achieved with four hexagon head screws with flange (DIN 6921), M10x30, strength class 8.8 and two spring dowel pins (DIN1481) Ø8x20 (not included).
