Mobile device for cutting e.g. polystyrene bodies with heating wire, has coupling elements connected with each other over coupling rod, so that rings and cutting wire are moved opposite to base plate when moving coupling elements

摘要

The device has a pivot (5) provided for coupling elements (3) at a base plate (1). The coupling elements and a guide element (2) comprise a guide for a slide ring (4). The slide ring and the guide element are arranged at a distance to each other so that a cutting wire is coupled to the slide ring of thrust linkages in form of thrust loops. The coupling elements of the linkages are connected with each other over a coupling rod, so that simultaneously the slide rings and the cutting wire are moved opposite to the base plate when moving the coupling elements. The base plate is made of wood material or composite material with metal foam.
