Glass forming device

Abstract

The invention belongs to the technical field of glass manufacture, and provides a glass forming device which comprises a base bar hanging component, a base bar driving component, a base bar softeningcomponent and a sub-bar stretching component which are sequentially and vertically arranged from top to bottom. The base bar driving component drives the base bar hanging component to move, glass basebars enter the base bar softening component downwards along with the base bar hanging component, and the sub-bar stretching component stretches the softened glass base bars into cylindrical glass sub-bars. The glass forming device further comprises a sub-bar measuring component, a sub-bar positioning guide component and a sub-bar cutting-off component. The glass forming device has the advantagesthat the stretching velocity of the glass sub-bars and the descent velocity and the softening temperature of the glass base bars can be automatically adjusted according to set diameters of target glass sub-bars, automatic shearing can be realized by presetting the lengths of the glass sub-bars, labor and raw material consumption is reduced, and small-diameter round bar glass is produced.

Description

technical field [0001] The invention belongs to the technical field of glass manufacturing, and in particular relates to glass forming equipment. Background technique [0002] In the glass production industry, there are many ways to produce round rod optical glass, such as pressing and forming with a glass molding machine, rolling with a glass rolling mill, and grinding with a cylindrical grinder. However, the glass press-forming process using the above-mentioned equipment all needs to make the glass sheet material into a semi-finished strip shape by a certain method, and then process it to obtain the desired glass shape. [0003] In the glass production process of the prior art, a large number of personnel are required in the material preparation process, the demand for labor is large, the consumption of raw materials is large, and it is difficult to produce and shape glass rods with a small diameter, especially for those with a diameter below φ8. Bar forming production is...
