Embodiment 1
[0017] A manufacturing process for pressing dimples of double-layer glasses, comprising the following steps:
[0018] (1) Wire drawing: arrange the sections of high-temperature-resistant glass tubes, burn the middle part of the high-temperature-resistant glass tube for 45 seconds, and after the middle part of the glass tube is burned red and softened, stretch the glass tube from both ends to seal the glass tube Drawing into a glass body with a closed cup bottom at one end and an open end at the other end. During the drawing process, natural gas and oxygen are used to burn the high-temperature glass tube, and the flame temperature is 900°C;
[0019] (2) Embryo blowing: The formed glass embryo body is fixed and supported and placed on the surface of the production table, and the glass embryo body is burned with a burning lamp. The burning temperature is 500°C for 60 seconds. Stop rotating the glass embryo body, and blow air into the softened glass embryo body with a blowing rod ...
Embodiment 2
[0024] A manufacturing process for pressing dimples of double-layer glasses, comprising the following steps:
[0025] (1) Wire drawing: arrange the sections of high-temperature-resistant glass tubes, and burn the middle part of the high-temperature-resistant glass tube for 65 seconds. After the middle part of the glass tube is burned red and softened, stretch the glass tube from both ends Drawing into a glass body with a closed cup bottom at one end and an open end at one end. During the drawing process, natural gas and oxygen are used to burn the high-temperature glass tube, and the flame temperature is 1700°C;
[0026] (2) Embryo blowing: Fix and support the formed glass embryo body and place it on the surface of the production table, burn the glass embryo body with a burning lamp, and blow air into the softened glass embryo body with a blowing rod to make it Become a hollow thick-walled vesicle, and then continue to blow into a material bubble;
[0027] (3) Embossing: burn...
Embodiment 3
[0031] A manufacturing process for pressing dimples of double-layer glasses, comprising the following steps:
[0032] (1) Wire drawing: arrange the sections of high-temperature-resistant glass tubes, burn the middle part of the high-temperature-resistant glass tube for 55 seconds, and after the middle part of the glass tube is reddened and softened, stretch the glass tube from both ends to seal the glass tube. Drawing into a glass body with a closed cup bottom at one end and an open end at one end. During the drawing process, natural gas and oxygen are used to burn the high-temperature glass tube, and the flame temperature is 1300°C;
[0033] (2) Embryo blowing: The formed glass embryo body is fixed and supported and placed on the surface of the production table, and the glass embryo body is burned with a burning lamp. The burning temperature is 600°C, and the burning time is 210s. Stop rotating the glass embryo body, and blow air into the softened glass embryo body with a blo...
