| 摘 要： | 为了解决激光切割钢化玻璃过程中由于热应力导致产生裂纹并发生破裂的技术难题,建立了光液耦合模型,采用FLUENT软件进行了耦合腔内多场分析,获得了微水导激光切割钢化玻璃的工艺参量。结果表明,在喷口口径为0.4mm、水束压力为20MPa、激光功率为48W、切割速率为20mm/s的工艺条件下,厚度为0.5mm及1.0mm的玻璃试样的切割表面均比较光滑、基体内无微裂纹存在,切缝宽度约为100μm。该双注水口耦合装置的设计是合理的,能够满足钢化玻璃切割工艺的要求。

| Abstract: | In order to solve the crack caused by thermal stress during the process of laser cutting for the toughened glass, the FLUENT software was adopted to analysis the water presure and the stability of water beam based on water & laser coupling model, and the optimised parameters were obtained.Then experiment based on the optimised parameters was conducted to verify the anslysis results.The results show that, incision surfaces of both No.1 and No.2 samples are smooth and slot with the width of 100μm under the condition of nozzle diameter 0.4mm, water pressure 20MPa, laser power 48W and cutting speed 20mm/s.Thedesign of coupling device with two water filling nozzles is applicable in the whole process of laser cutting for the toughened glass. |
