Tool holder for machine tool

摘要

Tool holder (1) has several tools (2), especially press dies, and is moved towards a bottom die (3) holding a workpiece (4). Each press die is fixed and non-moveable, and is moved into working position by a movement (B) of the tool holder. The tool holder has a rack (5), which meshes with a toothed gear. The gear is moved by a pneumatic cylinder, turned by a lever, and a cylinder movement causes the holder to be moved by one tool position. The tool holder is precisely positioned and fixed in place after reaching a working position.
