Mechanical
Clamping Nut

MKD

  • For all types of presses
  • For various die sizes and clamping dimensions
  • For clamping upper and lower dies
  • For dies with U-recess
  • For applications in the construction of jigs and fixtures

Mode of operation

  • The clamping nut is pushed manually into the U-recess of the die and the T-slot on the machine.
  • The clamping nut is then adjusted manually to the required clamping dimension.
  • The required clamping force is created by turning the operating hexagon clockwise with a wrench. A planetary gear provides a multiple torque increase.
  • Unclamping occurs by turning the operating hexagon counterclockwise.

Description

The transmission ratio provides multiple torque amplification which is then transmitted to the nut via the planetary wheels. The rotation of the nut causes the clamping stroke for the screwed-in T-bolt. The clamping force is safely applied, depending on the operating torque and the spring stiffness of the entire system. The clamping and operating forces are supported by axial bearings and a pressure plate directly to the machine bed or slide or the fixture. This clamping mechanism guarantees self-locking in all clamping positions. The line MKD is designed with a threaded through bore and a lateral operating hexagon.

Note

We recommend the use of a torque wrench in order to reliably guarantee the required clamping force and to protect the clamping mechanism from damage by excessively high torque. Under certain conditions, the use of a standard socket wrench, ring spanner of racketing end wrench may be acceptable for clamping. It must be ensured that the screwed-in T-bolts are tight, i.e. cannot turn with the clamp unit.
