Description

Technical Field

[0001] The invention relates to a flange pipe processing device, and more specifically to a quartz flange pipe thick-wall flanging device. Background Art

[0002] Quartz flange tube is a special industrial technical glass made of silicon dioxide, which has the advantages of high temperature resistance, corrosion resistance, good thermal stability, good light transmission and good electrical insulation. Since the softening point of quartz glass is about 1730℃ and the thermal expansion coefficient of quartz glass is very small, it can withstand drastic temperature changes. When quartz glass is heated to about 1100℃, it will not burst even if it is placed in room temperature water. Therefore, quartz flange tubes are widely used in various fields such as electric light sources, semiconductors, optical communications, military industry, metallurgy, building materials, chemistry, machinery, electricity, environmental protection, etc., and the processing and production of quartz flange tubes are gradually receiving widespread attention. When processing quartz flange tubes, it is necessary to use the function of the mold to form a flange with a certain angle along the edge of the unclosed curve. This process is called flanging of the quartz flange tube. When the existing quartz flange tube flanging machine is used, the thickness of the quartz flange tube wall is different, resulting in a poor overall appearance of the tube, uneven flanging thickness, low pass rate, unstable product quality, affecting normal use.
