Owing to the structure the utility model has the advantages of low consumption of pressure and optical energy, good convergence focusing effect, large width of the material to be cut, high rate of usage of plates, high intensity, high resistance to pressure, and high heat conductivity.
Description
One, technical field
The utility model relates to a kind of cutting processing equipment, particularly the laser cutting head of CO2 numerical control laser cutter.
Two, background technology
Digital-control laser cutting head is the critical piece of advanced cutting processing equipment CO2 numerical control laser cutter.Existing digital-control laser cutting head mainly is made up of critical pieces such as connecting tube, lens holder box, water-cooled assembly, focus lamp holder assembly, focusing lens, ventilation assembly, adjusting nut, high strength insulation separation sleeve, transient nozzles, cutting heads, the transient nozzles endoporus is a straight barrel type, the upper and lower part that constitutes the water-cooled assembly is the water-cooled external member that combines, and the critical piece material of laser cutting head adopts LY duralumin.There is following defective in such laser cutting head: the one, and the loss that straight barrel type transient nozzles endoporus has strengthened air pressure and light energy, focusing effect is relatively poor, focus diameter is bigger, influences cutting accuracy and cut quality, has reduced the sheet material utilization rate; The 2nd, bosh separates making with the external member main body, connects by silver brazing both are combined again, and not only manufacturing procedure is many, cost is high, and sealing is relatively poor, increases the loss of light energy; The 3rd, adopt LY duralumin at laser cutting head critical piece material, cannot say for sure to demonstrate,prove the requirement of laser cutting head high strength, high resistance to pressure, high-termal conductivity.
Three, summary of the invention
The purpose of this utility model provides that the loss of a kind of air pressure and light energy is little, focusing effect good, good airproof performance, the sheet metal thickness that is cut are bigger, sheet material utilization rate height and digital-control laser cutting head with high strength, high resistance to pressure and high-termal conductivity.
For realizing above purpose, the utility model digital-control laser cutting head comprises connecting tube, lens holder box, water-cooled assembly, focus lamp holder assembly, focusing lens, ventilation assembly, adjusting nut, high strength insulation separation sleeve, transient nozzles and cutting head, described transient nozzles endoporus is a back taper, and tapering is 15 °-20 °; The upper and lower part of described water-cooled assembly all is integral annular cooling water channel structures.
Adopt above technical scheme, desirable following effect:
1, through the accurately machined back taper transient nozzles of height endoporus, can reduce the loss of high pressure CO 2 gases and light energy to greatest extent, make the focus diameter that penetrates from cutting head littler than the focus that existing laser cutting head focuses on, the power density and the optical energy density of focus are bigger, cut quality and cutting efficiency have been improved greatly, the sheet metal thickness that is cut is bigger than the sheet metal thickness that the laser cutting machine with power can cut, and the sheet material utilization rate is higher.
2, the annular cooling water groove of water-cooled assembly is disposable machine-shaping, simple, the product precision height of processing technology, and low cost of manufacture, and the integral annular cooling water channel structure improved the cooling effect of water-cooled assembly effectively, and sealing reaches 100%.
Four, description of drawings
Fig. 1 is the utility model digital-control laser cutting head master cross-sectional schematic.
Five, the specific embodiment
As shown in Figure 1, the utility model digital-control laser cutting head mainly is made up of critical pieces such as connecting tube 1, lens holder box 2, water-cooled assembly 3, focus lamp holder assembly 4, focusing lens 5, ventilation assembly 6, adjusting nut 7, high strength insulation separation sleeve 8, transient nozzles 9, cutting heads 10.Transient nozzles endoporus 9-1 is a back taper, and tapering is 18 °; The upper and lower part of water-cooled assembly all is integral annular cooling water channel structures, and annular cooling water groove 3-1 is disposable machining moulding; The critical piece lens holder box 2 of digital-control laser cutting head, water-cooled assembly 3, focus lamp holder assembly 4, ventilation assembly 6 and adjusting nut 7 adopt extra-super duralumin LC4 to make.LASER Light Source is passed to laser cutting head by laser generator through light-conducting system during work, reach 100% water-cooling component 3 through connecting tube 1, lens holder box 2, sealing, reach focus lamp holder assembly 4, by focusing lens 5 LASER Light Source is focused on, laser beam 11-1 after the focusing is through ventilation assembly 6, separation sleeve 8, transient nozzles 9, the central small hole 10-1 of Φ 1.5 penetrates from the cutting head 10, and is littler than conventional focus to form, the laser beam 11-1 that the power density of focus and optical energy density are bigger; And pressure reaches 2 * 10
6The high pressure CO of Pa
2The cutting assist gas reaches 100% ventilation assembly 6 through sealing and sends into laser cutting head, on the one hand focusing lens 5 is lowered the temperature, keep the cleaning of eyeglass and indeformable, keep hyperbar central small hole of Φ 1.5 from the cutting head 10 to export on the other hand with the coaxial high pressure of laser beam 11-1; The high pressure CO of output
2The laser beam 11-1 of assist gas 11-2 and high-energy-density to sheet material carry out high-precision, high-quality, at a high speed, the cutting of efficient, little surplus, expanded the cut coverage and the cutting performance of laser cutting machine.
