Description

Technical Field

[0001] The utility model relates to the technical field of quartz tube expanders, in particular to a cooling device for a quartz tube expander. Background Art

[0002] Quartz tube is a special industrial technical glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties. It is used in electric fire buckets, electric stoves, and electric heaters to generate heat. Quartz tubes of different diameters are installed according to demand, but this results in high product consumption. It is necessary to purchase quartz tubes of various diameters, resulting in a waste of raw materials and a significant increase in procurement funds. Therefore, it is sometimes necessary to expand the purchased quartz tube according to the diameter size requirements of the installation equipment. Because the hot melting temperature of quartz tube is relatively high, the traditional quartz tube expansion process is more about placing the quartz tube in a rotating box after high-temperature treatment and rotating it at high speed to achieve tube expansion through centrifugal force.

[0003] For example, the utility model patent with announcement number CN217677291U discloses a variable diameter quartz tube expanding device, including a base, a lifting device and a graphite wheel. Chucks are symmetrically arranged on both sides of the upper end of the base, and the quartz tube is clamped on the chucks. The base is provided with a first motor, a first lead screw and a slide rail. The first motor is arranged on one side of the lower end of the base. The first lead screw and the slide rail are parallel to the quartz tube and arranged at the lower end of the base. The first lead screw is driven by the first motor, and the slide rail is arranged on the base. One side of the lower end of the base is connected to the first lead screw, and the other side is connected to the slide rail. The second motor is arranged above the base, and the second lead screw vertically passes through the center of the horizontally arranged worm gear and is connected thereto. The second motor drives the worm to drive the worm gear to rotate, and the second lead screw rises or falls through the rotation of the worm gear.

[0004] However, most of the rollers in the cooling device of the existing pipe expander are solid structures, which makes it difficult to quickly cool them during long-term continuous processing, resulting in poor performance. Utility Model Content
