Abstract
The invention relates to a blowing device ( ) for a laser system ( ) used for separating or welding workpieces ( ). The blowing device ( ) has at least one nozzle assembly ( ), which generates a gas stream ( ) that is oriented at an angle to the laser beam ( ). The blowing device also has an air supply ( ) which, on one side of the nozzle, leads into the proximity of the nozzle opening ( ) and which is provided for an air supply stream ( ) that is fed to the gas stream ( ) in an essentially parallel manner or at an apex angle. A second air supply ( ) is arranged on the other side of the nozzle. Said second air supply leads into the proximity of the nozzle opening ( ) and is provided for a second air supply stream ( ) that is fed to the gas steam ( ) in an essentially parallel manner or at an apex angle. A protecting glass ( ), which is oriented toward the gas stream ( ) in an essentially parallel manner, can be alternatively or additionally placed in the proximity of the nozzle opening ( ). Said protecting glass is provided in the form of a pane and directly abuts against the nozzle opening ( ) in a sealed manner. In the preferred embodiment, the outer cross-section of the nozzle ( ) is provided in the shape of a drop or a vane, whereby at least the outer surfaces thereof extending toward the nozzle opening ( ) form air conducting surfaces ( ).
