Description

A Portable Quartz Tube Circulator

technical field

The invention belongs to the field of mechanical design, and relates to a portable quartz tube circumcutter.

Background technique

1. Quartz tube and its application

The full name of quartz tube is quartz glass tube, which refers to special industrial glass made of silica as a component. Quartz tube is a very important basic material with excellent physical and chemical properties. It has been widely used in electric light sources, semiconductors, optical communications, military industry, metallurgy, building materials, chemistry, machinery, electricity, and environmental protection worldwide. and other fields. Therefore, accurate and quick quartz tube ring cutting operation is also of great significance.

2. The methods, tools and disadvantages of traditional circumcision quartz tubes

There are three methods for traditional quartz tube ring cutting: scribing method; burning rope soaking method; cutting with glass tube cutting machine.

(1) The scribing method refers to using a glass knife to draw marks on the quartz tube, and then breaking or knocking it hard. Although this method is simple and quick, there are unavoidable shortcomings such as uneven cross-section and even irregular fragmentation of cross-section.

(2) The burning rope soaking method refers to tying a circle of thin wire on the position of the quartz tube that needs to be cut, and then igniting the string. Once the string is burned, immediately immerse the quartz tube in water, and use thermal expansion and contraction to make the quartz tube A temperature difference is generated locally in the tube, and then a neat fracture occurs to achieve the purpose of circumcision. Although this method can accurately select the circumcision position, there are unavoidable shortcomings such as complex operation, danger (requires hot fire), easy introduction of pollutants during the immersion process, and is not suitable for use environments with high cleanliness requirements.

(3) The glass tube cutting machine has the inevitable disadvantages of high energy consumption, high noise, and non-portability. Obviously, it is not suitable for a glove box with a small space and high cleanliness requirements or other environments without power supply.

To sum up, inventing a tool that is portable, quiet, energy-free, and capable of accurately performing quartz tube circumcision has become a top priority for quartz tube circumcision.

Detailed ways

Method of use: place the quartz tube to be ring-cut at the open end of the ring cutter (between the diamond and the rollers), and slowly rotate the knob downwards so that the diamond and the two roller groups are in contact with the ring cutter to be cut. The outer wall of the quartz tube is in close contact, and then slowly rotate the quartz tube in the same direction, so that the diamond will leave scratches on the outer wall of the quartz tube, continue to rotate while gently turning the knob to keep the diamond in close contact with the outer wall of the quartz tube, and rotate After 1-2 weeks, remove the quartz tube and gently tap the scratched area, the quartz tube will naturally break neatly along the scratch, and the circumcision is complete.
