Problems solved by technology

This production method is complicated in process and low in efficiency. In addition to high requirements for supporting kilns and related equipment, it also requires high production level of specific operators; The thickness of the cup wall is uneven, and the transparency of the finished product is poor
These two methods have the problems of low production efficiency, high processing cost per cup, poor transparency of finished products, and high requirements for production environment supporting facilities.

Embodiment 1

[0031] Embodiment one: see figure 1 shown, including the following steps:

[0032] A. Cutting process: Clamp both ends of the glass tube material with a diameter of 47 mm and a wall thickness of 1.8 mm on the rotating device. Both ends are supported and rotated synchronously. At the set length, use a glass knife to cut a piece horizontally along the glass tube material. The circle is roasted with fire to make it break, and the glass tube material is cut into several sections of glass tube material sections with twice the height of the finished glass cup and a length of 160 mm.

[0033] B. Bottom forming process: Firstly, the two ends of the cut glass tube are clamped on the rotating device, both ends are supported and rotated synchronously, and the speed is 50 rpm. Use a flame to locally heat the middle part of the pipe until the glass softens. The heating temperature is 820°C and the heating time is 45 seconds. Using a blade made of graphite with a thickness of 18 mm, slowl...

Embodiment 2

[0036] Embodiment two: see figure 1 As shown, it is basically the same as Example 1, and will not be repeated. The difference is that the diameter of the glass tube material is 53 millimeters, the rotating speed in the bottom forming process is 60 rpm, the heating temperature is 900 ° C, and the heating time is 40 seconds. Cut with a graphite knife with a thickness of 20 mm.

Embodiment 3

[0037] Embodiment three: see figure 1 As shown, it is basically the same as Example 1 and will not be repeated. The difference is that the diameter of the glass tube material is 58 mm and the wall thickness is 2 mm. For 35 seconds, cut with a graphite knife with a thickness of 21 mm.

Abstract

The invention relates to a method for producing a single-layer glass cup by using a glass tube. The method comprises the following steps: A. material cutting process: the glass tube is cut into the glass tube material section with the height which is twice that of the finished glass cup; B. bottom forming process: the both ends of the cut glass tube material are clamped on a rotary device to locally heat the middle part of the tube material till the softening of the glass, a heat-resistant material blade with the thickness which is less than the width of a heating zone and does not have the affinity with the glass is used for cutting the middle part of the heating zone to form blanks of two cup bottoms; C. cup bottom processing process: the cup-shaped glass tube material is clamped on the rotary device, flames are used for heating the bottom part of the glass cup-shaped tube material along the transverse direction at the same time of rotation till the melting of the glass, and the cup bottoms are thickened to meet the design requirements. The method has simple production technology, greatly improved yield, good overall transparency of the cup and no need of polishing. The production efficiency is greatly improved, and the method can be used for large-scale production and family workshop operation. The equipment cost is greatly reduced, and the method can be used for the production by only using a special burning device, thereby eliminating the constraints of a kiln on the production scale and the place.

Description

1. Technical field [0001] The invention relates to a method for making a glass, in particular to a method for making a single-layer glass with a glass tube. 2. Background technology [0002] At present, there are mainly two methods for making single-layer glass. One is the compression molding method, which uses the stamping of the punch to force the high-temperature glass liquid to form in the mold. The production of glass cups by this production method requires supporting kilns, and the requirements for related equipment are relatively high. The other is the blow molding method, which uses the pressure of air pressure to shape the high-temperature molten glass in the mold. This production method is complicated in process and low in efficiency. In addition to high requirements for supporting kiln and related equipment, it also requires high production level of specific operators; The thickness of the cup wall is uneven, and the transparency of the finished product is poor....
