Technical Field

[0001] The utility model relates to an automatic quartz tube cutting device, in particular to an automatic quartz tube cutting device. Background Art

[0002] Quartz tube is a special industrial technical glass made of silicon dioxide, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties. The formation of quartz glass is the result of its high viscosity at high temperature. It is widely used in the production of semiconductors, electric light sources, semiconductor communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment, high temperature and corrosion resistant chemical instruments, chemical industry, electronics, metallurgy, building materials and national defense industries.

[0003] The mechanical properties of quartz glass are better than those of hard glass and ceramics, but its brittleness is poor. The theoretical strength of quartz glass is very high, about 24×103MPa, but the actual measured strength is dozens of times lower than this value. The main factors affecting the strength are the surface defects of the glass, especially the size and depth of the surface microcracks. The flexural strength of finely ground quartz glass samples is about 0.6 times higher than that of coarsely ground samples; the second is internal defects, such as bubbles, impurities, uneven melting and residual stress.

[0004] The production of quartz tubes generally involves first melting the quartz stone in a continuous melting furnace, then drawing it into shape, and then cutting the quartz tubes into the required lengths after they come out of the furnace.
