Description
Technical field
The utility model relates to a kind of laser cutting system optical laser cutting head, belongs to technical field of laser processing.
Background technology
Laser cutting is to utilize the scanned material surface of laser focusing bundle of high power density, at the utmost point, in the short time, material is heated 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, thereby 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, and thermal deformation and machining deformation are little.Laser beam focal beam spot is little, can carry out meticulousr micro-processing, 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 demand that the domestic demand to Materialbearbeitung mit Laserlicht, especially optical-fiber laser cut 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, has greatly limited 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 these several major parts connect from top to bottom in turn, and their axial centre is positioned on same axis.Fibre-optical splice wherein, for being connected with the optical fiber output unit of laser generator, receives laser.Because the laser receiving belongs to diverging light, need to adjust incident angle of light with level(l)ing device, the laser of dispersing is converted to parallel laser and could continue to use by being arranged on the collimation lens of level(l)ing device inside.Parallel laser after adjusting passes through the focusing lens in focus control again, arrives cutting surfaces; In order to obtain best cutting effect, can rotate the focusing knob on focus control, according to sheet metal thickness, adjust to most suitable focus.Protective glass device, for by extraneous isolated with the light path of cutting head inside, guarantees the sealing of light path, prevents that dust and impurity from entering light path, extends the service life of whole optical laser cutting head.Gas operated device is for cutting at Laser cutting process auxiliary laser.Cutting head is connected under gas operated device, sensor is installed on cutting head, sensor connector is connected with Linear Driving control circuit with transducing signal treatment circuit, can make the distance between cutting head and surface of the work keep stable for a long time, reliably, for obtaining best cut quality, gives security.
