Laser plasma dual-use cutting machine

Abstract

The invention discloses a laser plasma dual-use cutting machine which comprises a beam which is connected with a lathe bed in a transmission mode. A drag plate is connected with the beam in the transmission mode. A working table and a drag chain are fixedly connected with the lathe bed. An yttrium aluminum garnet (YAG) solid laser generator is arranged on the drag plate. The YAG solid laser generator is provided with a light dipping supporting plate. Two sets of lifting mechanisms are connected with the light dipping supporting plate in an installing mode, one set of lifting mechanisms is connected with a double-focal-distance cutting head in the installing mode, and the other set of lifting mechanisms is connected with a plasma cutting torch in the installing mode. The lathe bed is further provided with a rotary cutting pipe chuck and a rotary cutting pipe supporting frame. A laser cutting head and a numerical control plasma cutting head are both arranged on a numerical control cutting machine, and the laser cutting head and the numerical control plasma cutting head are reasonable in structure. Different processing requirements of workpieces can be met by the solid laser generator and the double-focal-distance cutting head, wherein the mirror spacing of the solid laser generator is convenient to adjust, the solid laser generator is good in dust-proof effect, and the double-focal-distance cutting head is capable of changing focal distances rapidly and high in processing precision. The laser plasma dual-use cutting machine particularly conducts cutting on metal tubular products.

Description

technical field [0001] The invention relates to an industrial cutting equipment, especially a laser plasma dual-purpose cutting machine Background technique [0002] Existing CNC cutting machines mainly include two types of CNC laser cutting machines and CNC plasma cutting machines. The function is single, and the processing accuracy cannot be compared with the CNC laser cutting machine. Although the general laser and plasma dual-purpose cutting machine can combine the advantages of the two, due to the mutual interference of the cutting head settings, it can only be used interchangeably. It brings trouble, and the existing CNC laser cutting machine and CNC plasma cutting machine generally can only cut metal sheets. The position between the cutting head and the cutting head needs to be constantly adjusted, which poses a problem for plasma and laser cutting machines to cut pipes, making plasma and laser cutting machines unable to be widely used in pipe cutting.

[0002] Existing CNC cutting machines mainly include two types of CNC laser cutting machines and CNC plasma cutting machines. The function is single, and the processing accuracy cannot be compared with the CNC laser cutting machine. Although the general laser and plasma dual-purpose cutting machine can combine the advantages of the two, due to the mutual interference of the cutting head settings, it can only be used interchangeably. It brings trouble, and the existing CNC laser cutting machine and CNC plasma cutting machine generally can only cut metal sheets. The position between the cutting head and the cutting head needs to be constantly adjusted, which poses a problem for plasma and laser cutting machines to cut pipes, so that plasma and laser cutting machines have not been widely used in pipe cutting

[0003] At the same time, during laser cutting, solid-state laser generators are generally used as lasers for metal cutting and welding. Solid-state laser generators generally include red light mirrors, reflectors, condenser cavities, half mirrors, beam expanders, etc. Solid-state laser generators Adjusting the distance between various mirrors in use is an important factor affecting the laser generation parameters. At the same time, because solid-state laser generators are widely used as metal cutting and welding lasers, the use environment i...
