A laser processing device for metal material mesh structure parts

Abstract

The invention discloses a laser machining device for metal parts of reticular structure. The laser machining device comprises a support frame, wherein a placement plate is integrally formed at the upper end of the support frame; a workpiece is placed on the placement plate; a fixed frame is mounted on the side, of the placement plate, close to the workpiece; a guide rail is welded to and arrangedbetween a beam of the fixed frame and the placement plate; and a laser device is connected to the guide rail in a sliding manner. According to the laser machining device, linkage mechanisms are drivenby drive mechanisms, so that at the beginning of machining the workpiece, sliding baffle plates can be extended out from connecting covers to block the light generated during machining, thereby greatly reducing the damage to the eyes of workers during laser machining as well as the light pollution in a workplace; and through the forward and reverse rotation of servo motors, the sliding baffle plates are controlled to extend out of or retract into the connecting covers, so that the overall operation is easier and can be completed without the need of many operation steps, thereby improving theefficiency of light blocking.

Description

technical field [0001] The invention relates to the technical field of laser mechanics, in particular to a laser processing device for metal material mesh structure parts. Background technique [0002] Laser processing uses the energy of light to reach a high energy density at the focal point after being focused by a lens, and is processed by photothermal effects. Laser processing does not require tools, has fast processing speed, and small surface deformation. It can process various materials. Beams are used for various processing of materials, such as punching, cutting, scribing, welding, heat treatment, etc.; [0003] When the laser hits the metal of the workpiece, it is easy to reflect light through the metal of the workpiece, which will easily cause serious light pollution in the workplace and cause damage to the eyes of the staff. Contents of the invention [0004] The purpose of the present invention is to solve the problem in the prior art that laser technicians a...
