Description
Technical field
The present invention relates to a kind of laser cutting system optical laser cutting head, belong to technical field of laser processing.
Background technology
Laser cutting is the scanned material surface of laser focusing bundle utilizing high power density, in very short time by heating materials to several thousand even up to ten thousand degrees Celsius, make material instant melting or vaporization, with gases at high pressure, fusing or vaporization material are blown away from joint-cutting again, thus reach the object of cutting material.
Fiber cut is higher than the faster efficiency of traditional cutting speed, and process time is short, and heat affected area is little, thermal deformation and machining deformation little.Laser beam focus hot spot is little, can carry out meticulousr micro Process, and conduction is more superior with focusing performance, and power and energy are easily controlled.The modular mechanical component design of compact and portable, weight is light, is particularly suitable for factory floor and uses.
In recent years the domestic demand to Materialbearbeitung mit Laserlicht, the demand of especially optical-fiber laser cutting increases sharply.And home equipment in recent years sales volume also increase, the laser enterprise developed recently impetus is swift and violent.But make a general survey of these laser enterprises, the technical merit of its main high-end core component---optical laser cutting head is still not high, significantly limit further developing of laser cutting industry.
Optical laser cutting head generally comprises fibre-optical splice, level(l)ing device, focus control, protective glass device, gas operated device and the several leading major part of cutting, and this few major part connects from top to bottom in turn, and their axial centre is positioned on same axis.Fibre-optical splice is wherein used for being connected with the optical fiber output unit of laser generator, receives laser.Because the laser received belongs to diverging light, need to adjust incident angle of light with level(l)ing device, convert by the collimation lens being arranged on level(l)ing device inside the laser dispersed to parallel laser and could continue to use.The focusing lens of parallel laser after adjustment again in focus control, arrives cutting surfaces; In order to obtain best cutting effect, the focusing knob on focus control can be rotated, adjust to most suitable focus according to sheet metal thickness.Protective glass device is used for the extraneous light path with cutting head inside to completely cut off, and ensures the sealing of light path, prevents dust and impurity from entering light path, extend the service life of whole optical laser cutting head.Gas operated device is used for auxiliary laser cutting in Laser cutting process.Cutting head is connected under gas operated device, cutting head is provided with sensor, sensor connector is connected with transducing signal treatment circuit and linear drive control circuitry, and the distance between cutting head and surface of the work can be made for a long time, reliably to keep stable, gives security for obtaining best cut quality.
