An ultrasonic assisted forming method of capillary glass tubes for optical detection
PendingCN122079473AInhibition formationImprove the finishGlass making apparatusCore needleMolten state
This application provides an ultrasonic-assisted forming method for capillary glass tubes used in optical inspection, applied to a forming apparatus including an ultrasonic base and a metal core needle. After preheating the forming apparatus to a first temperature, molten glass is poured in, causing it to coat the core needle and tend to form a transiently solidified layer. An acoustic model is established by collecting the effective working length of the core needle and the material's acoustic parameters. Based on the acoustic model and considering the critical energy density required to destroy the transiently solidified layer and the effective glass forming time, the acoustic energy output parameters of the core needle are determined. According to these parameters, high-frequency ultrasound is continuously applied through the ultrasonic base during the cooling process of the glass from the molten state to a second temperature, causing the core needle to vibrate to destroy and suppress the transiently solidified layer. The ultrasound is then turned off. This method can reduce interfacial stress concentration, suppress the formation of microcracks on the inner wall, and improve the smoothness of the inner wall of the capillary glass tube as well as its optical and mechanical properties.
