LASER NOZZLE HAVING A MODULAR MOBILE ELEMENT MADE OF ELECTRICALLY INSULATING MATERIAL AND AN INSERT MADE OF ELECTRICALLY CONDUCTIVE MATERIAL

摘要

The invention relates to a nozzle for laser cutting, comprising a nozzle body (1) comprising a first axial housing (5), a mobile element (2) formed from an electrically insulating material and comprising a second axial housing (4), said mobile element (2) being arranged in the first axial housing (5), and an elastic element (8) arranged in the first axial housing (5) between the nozzle body (1) and the mobile element (2). According to the invention, the nozzle also comprises an insert (3) comprising an axial passage (18) and a front part (3a) forming a skirt that projects outwards from the second axial housing (4), said insert (3) being arranged in the second axial housing (4) of the mobile element (2) and being formed from an electrically conductive material. The present invention describes an associated laser head and installation, and also a laser cutting process implementing such a nozzle.
