Problems solved by technology

[0002] At present, there are two kinds of production methods for the goblet glasses sold on the market. One is to blow the glass liquid on the mould. The goblet glasses made by this method have poor brightness, complicated processing technology and high reject rate. The other is that the cup body and the cup neck are made in sections, and t...

Embodiment Construction

[0011] figure 1 Shown, be a kind of concrete embodiment of the method for making goblet with glass tube of the present invention, it may further comprise the steps:

[0012] A. Cutting process 1: Cut the glass tube into a glass tube section corresponding to the goblet glass. The size of the glass depends on the size of the glass tube;

[0013] B. Cup neck production process 2: First, position the glass tube section on the special firing equipment, and rotate the glass tube section; then aim at the cup neck and gradually blow air to heat to 1000°C-1400°C to soften the glass tube; The neck of the cup is press-molded on the neck of the cup to make the glass tube shrink and deform inward until the diameter of the tube hole is less than 1 cm; separate the die from the neck of the cup, continue to blow air and heat it to 1400°C-1600°C to melt the glass, so that the glass tube is melted into Solid column, the bottom of the cup is naturally concave toward the neck of the cup; and the...

Abstract

The present invention discloses a method for making goblet by using glass tube, which comprises the following steps: A. blanking procedure: cutting a glass tube into glass tube sections; B. cup neck making procedure: air blowing and warming up the cup neck gradually until the glass tube is softened, then pressing the cup neck die on the cup neck position to make the glass tube contract and distort towards the inside, separating the cup neck pressing die and going on with air blowing and warming up until the glass is melted to a column shape, then doing annealing treatment; C. cup bottom making procedure: air blowing and warming up the cup bottom to make the glass tube contract and distort towards the inside until it is melted and cut off, the cup bottom forms a flat bottom; D. cup mouth making procedure: polishing the blank cup mouth and warming it up to form a circle. The invention has the advantages of simple production process, convenient operation, high yield, etc.

Description

1. Technical field [0001] The invention relates to a method for making a glass, in particular to a method for making a tall glass with a glass tube. 2. Background technology [0002] At present, there are two kinds of production methods for the goblet glasses sold on the market. One is to blow the glass liquid on the mould. The goblet glasses made by this method have poor brightness, complicated processing technology and high reject rate. The other is that the cup body and the cup neck are made in sections, and then bonded together. This method improves the yield rate compared with the above method, but it also has the problems of poor brightness and complicated processing technology. In addition, the finished cup has The obvious interface affects the appearance of the glass, and the interface is easy to break, which shortens the service life of the glass. 3. Contents of the invention [0003] In order to overcome the above-ment...
