Nozzle method for removing dust and chips resulting from drilling operations

摘要

A nozzle removes by suction dust and chips from a drilling machine in an industrial plant. The nozzle has a first tubular portion for connection to a suction tube communicating with an opposite second tubular portion with an intake opening. An outer flange extends transversely from an intermediate position between the first and second tubular portions. The intake opening is directed in a lateral direction, parallel to the transverse direction of the flange. A magnetic element is incorporated in the flange. The nozzle can be applied to a drilling template having cylindrical through-openings in which respective bushings made of ferromagnetic material are fixed. When the second tubular portion is inserted through a cylindrical bushing, the magnetic element acts on the bushing, opposing axial and rotational movements of the nozzle.

1. A nozzle for removing by a suction system dust and chips resulting from a drilling apparatus in an industrial plant, the nozzle comprising:
two opposite end portions communicating with one another: a first tubular portion suitable for connection to a tube connected to a suction system, and a second tubular portion having an intake opening; an outer flange extending transversely from an intermediate position between the first tubular portion and the second tubular portion, the intake opening being directed in a lateral direction parallel or substantially parallel to the transverse direction of the flange; at least one magnetic element incorporated in the nozzle; the nozzle being applicable to a drilling template having a plurality of cylindrical through-openings in which respective cylindrical bushes made of ferromagnetic material are fixed, so that when the second tubular portion is inserted through a cylindrical bushing, the magnetic element acts magnetically on the bushing, opposing axial and rotational movements of the nozzle with respect to the template.
