[0039] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0040] A method for stretching a glass preform, which is to clamp the upper end and the lower end of a glass preform 2 respectively on an upper fixture 1 and a lower fixture 5 for sequential heating, using the speed V1 of the upper fixture 1 and the speed V2 of the lower fixture 5 The difference between them is to stretch the glass preform 2. During the stretching process, the stability of the stretching force F is always ensured by adjusting the speed V1 of the upper clamp 1, and the diameter D0 and the setting of the caliper 4 are used to control the Measure the speed V2 of the clamp 5 under the control of the fixed-point diameter D01, which is characterized in that: the internal tension of the glass preform reflecting the stretching force F is measured by the gravity sensor 12, and the volume of the glass preform is constant during the stretching p...
