Crimphöhen-Einstellmechanismus

摘要

The mechanism is for use in a crimping machine having an anvil and a ram. The ram is secured against rotation and guided for reciprocal movement along a ram axis for moving the crimping die toward and away from the anvil. A drive member is connected for reciprocating the ram. The adjustment mechanism includes a first member fixed w.r.t. the anvil and having a first threaded portion of a first thread pitch extending along an adjustment axis parallel to the ram axis. A second member has a second threaded portion coaxial to the first threaded portion. The second threaded portion has a second thread pitch which differs from the first thread pitch. The second member is secured against rotation and coupled to move the ram linearly along the ram axis. A third member has both a third threaded portion which is threaded to the first threaded portion and a fourth threaded portion which is threaded to the second threaded portion. The third member is rotatable about the adjustment axis to change an extent of engagement with the first and second threaded portions. Rotation of the third member about the adjustment axis produces a linear movement of the second member which is equal to a number of rotations of the third member multiplied by a difference between the two pitches.
