A kind of laser cutting machine and its cutting method

Abstract

The invention relates to the technical field of laser cutting machines, in particular to a laser cutting machine and a cutting method thereof. A laser cutting machine, comprising, a machine tool platform, a clamping fixture, a launch device for emitting laser light and a first shielding gas, a first moving mechanism for moving the clamping fixture, a second moving mechanism for moving the launch device The moving mechanism and the blowing mechanism for blowing the second protective gas; the launch device includes an injection nozzle arranged above the clamping jig and emits laser light and the first protective gas in the same direction; the blowing mechanism includes the same nozzle as the injection nozzle. The air blowing nozzles with opposite shafts; the clamping jig is provided with an air blowing channel for blowing the second protective gas. The laser cutting machine can be mass-produced, has the advantages of high efficiency and low production cost, and the laser cutting machine can make the cut alloy products have the advantages of less burrs, small burrs, and good quality of the cut surface.

Description

technical field [0001] The invention relates to the technical field of laser cutting machines, in particular to a laser cutting machine and a cutting method thereof. Background technique [0002] Laser cutting machines are widely used in the cutting of various alloys (including crystalline alloys and amorphous alloys). The laser cutting machine in the prior art has the defect that it is difficult to produce in large quantities, that is, in the production process of the existing laser cutting machine, only one or two products can be clamped and cut as a unit in each batch. Lead to low production efficiency, unable to meet the needs of mass production. The reason is that if the existing laser cutting machine is to change dozens of products into one unit for clamping and cutting, the jigs for clamping the products will become very complicated, and the space of the existing laser cutting machine cannot satisfy dozens of products. The product is cut in one unit, and the ventila...

The laser cutting machine in the prior art has the defect that it is difficult to produce in large quantities, that is, in the production process of the existing laser cutting machine, only one or two products can be clamped and cut as a unit in each batch. Lead to low production efficiency and cannot meet the needs of mass production

The reason is that if the existing laser cutting machine is to change dozens of products into one unit for clamping and cutting, the jigs for clamping the products will become very complicated, and the space of the existing laser cutting machine cannot satisfy dozens of products. The product is required to be cut in one unit, and the ventilation air path of the laser cutting machine will become complicated and difficult to realize, and the production cost will become high

In addition, after the existing laser cutting machine cuts the alloy product, the cutting surface of the product has the disadvantages of a large number of burrs and a large burr size, resulting in unsatisfactory quality of the cutting surface
