Dust collection device on laser cutting machine

Abstract

The invention discloses a dust collection device on a laser cutting machine. The dust collection device comprises a transverse feeding main beam, and a transverse guide rail is fixed to the upper endface of the feeding main beam; a dust collection cover is fixed to the lower end face of the feeding main beam; a plurality of transverse dust collection grooves are formed in the side wall of one side of the dust collection cover; a dust discharge shell which communicates with the dust collection grooves is fixed to the outer side wall of the dust collection cover; a dust discharge pipe which communicates with the dust discharge shell is fixed to the outer side wall of the dust discharge shell; insertion grooves are formed in the lower end face of the dust discharge shell; a plurality of L-shaped valve plates are inserted in the insertion grooves of the dust discharge shell; the valve plates abut against the outer side wall of the dust collection cover and cover the dust collection grooves of the dust collection cover; the adjacent valve plates abut against each other; the valve plates are composed of vertical parts inserted on the dust discharge shell and horizontal parts on the lower side of the dust discharge shell; a supporting plate is fixed to the lower end face of the dust discharge shell; cylinders are fixed to the supporting plate; and piston rods of the cylinders are fixed to the horizontal parts of the valve plates. According to the dust collection device, dust collection can be achieved during laser cutting of specific parts, and energy consumption is effectively reduced.

Description

Technical field: [0001] The invention relates to the technical field of laser processing, in particular to a dust suction device on a laser cutting machine. Background technique: [0002] The laser cutting machine focuses the laser light emitted from the laser device into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. The laser cutting machine will produce powder when cutting, and the operator will cause respiratory infection after inhaling a large amount of dust after working for a long time, which will endanger people's health; so some laser cutting machines are equipped with dust suction structures, and some laser cutting machines have laser The device is arranged on the guide rail that can move longitudinally, and the guide rail ...

Problems solved by technology

The laser cutting machine will produce powder when cutting, and the operator will cause respiratory infection after inhaling a large amount of dust after working for a long time, which will endanger people's health; so some laser cutting machines are equipped with dust suction structures, and some laser cutting machines have laser The device is arranged on the guide rail that can move longitudinally, and the guide rail is fixed on the beam body that can be fed horizontally. The lower side of the beam body is fixed with a dust suction cover, and the dust suction cover is connected with the suction pipe to realize the dust suction on the lower side of the beam body. The whole shell is vacuumed, that is, the part that is not laser cut is also vacuumed during vacuuming; the energy consumption required for vacuuming is relatively large
