Drawing device and method for small-batch multi-variety high-uniformity glass tubes

Abstract

The invention discloses a drawing device and method for small-batch multi-variety high-uniformity glass tubes and belongs to the technical field of special glass manufacturing. The invention mainly aims to solve the problems of unstable drawing quality, low yield and the like of special application glass tubes with small market demand and multiple varieties (formulas). The drawing device is mainly characterized by comprising a forming furnace body, a material basin, a material homogenizing barrel, a leading-in pipe, a stirrer and a forming part, the material basin is arranged in the forming furnace body, the leading-in pipe is located on the upper portion of the forming furnace body and is coaxial with a leading-in hole in a cover plate, and an outlet of the leading-in pipe extends into the leading-in hole, the material uniformizing barrel is coaxial with a leakage opening in the material basin, and a certain gap is kept between the lower edge of the material uniformizing barrel and the inner bottom surface of the material basin, the stirrer is arranged inside or outside the material uniformizing barrel and is coaxial with the material uniformizing barrel, and the forming part is arranged at the lower part of the forming furnace body. The drawing quality of small-discharge-amount glass tube forming can be solved with a specific process method. The drawing device is mainly used for drawing small-batch multi-variety high-uniformity glass tubes.

Description

technical field [0001] The invention belongs to the technical field of special glass manufacturing, and in particular relates to a drawing device and method for small-batch, multi-variety and high-uniformity glass tubes. Background technique [0002] Glass tube is a widely used glass product. Common glass tubes are mainly used in solar water heaters, medicinal glass bottles and other fields. The characteristics of glass forming are large output, fast drawing speed, and single glass varieties. The product formula basically does not change. Therefore, the molding quality of the glass tube is high, and the diameter and wall thickness are uniform. [0003] However, for glass tubes used in some special industries, the market demand is small, there are many types of glass formulas, and the formulas are often switched frequently, so that large-scale industrial production methods cannot be adopted, and manual drawing or blowing is used, and the yield rate is low. , The quality of ...

[0003] However, for glass tubes used in some special industries, the market demand is small, there are many types of glass formulas, and the formulas are often switched frequently, so that large-scale industrial production methods cannot be adopted, and manual drawing or blowing is used, and the yield rate is low. , The quality of the finished pipe is poor, the pipe diameter and wall thickness cannot be effectively guaranteed, and at the same time, the requirements for the skills of the workers are extremely high, which seriously hinders the development of the special glass pipe industry
