Description

Technical Field

[0001] This utility model relates to the technical field of quartz tube production equipment, specifically to a quartz tube production device with adjustable spiral quartz tube dimensions. Background Technology

[0002] Quartz tubes are widely used in semiconductors, photovoltaics, lighting, and laboratory equipment due to their excellent high-temperature resistance, chemical stability, and optical properties. In practical applications, helical quartz tubes, with their compact structure and efficient heat / mass transfer characteristics, have become key components in many industrial scenarios. However, existing quartz tube helical bending equipment has significant technical limitations and needs improvement to meet diverse production needs.

[0003] Traditional quartz tube spiral bending equipment typically uses fixed-size molds or guiding mechanisms, which can only bend quartz tubes with specific outer diameters. When production needs involve quartz tubes with different outer diameters (such as Φ10mm to Φ50mm), frequent mold changes or equipment parameter adjustments are required, leading to low production efficiency and increased costs. With the advancement of Industry 4.0, small-batch, multi-variety customized production has become a trend, but traditional equipment cannot quickly respond to the processing needs of quartz tubes of different specifications.

[0004] Therefore, we propose a quartz tube production device with adjustable spiral quartz tube dimensions. Utility Model Content

[0005] The purpose of this invention is to provide a quartz tube production device with adjustable spiral quartz tube dimensions to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quartz tube production device with adjustable spiral quartz tube size, comprising a base, a mandrel and an oxyhydrogen flame torch, wherein a first adjustment mechanism and a second adjustment mechanism are provided on the top of the base; The support column is fixedly installed on the top of the base; The fixing plate is fixedly installed on the top of the support column; The first adjustment mechanism includes a sleeve and a lifting rod, wherein the lifting rod is installed inside the sleeve; A telescopic rod is installed on the upper part of the lifting rod, and an oxyhydrogen flame spray gun is installed on the right end of the telescopic rod. The mandrel mounting rod has its left end fixedly mounted on the support column, and the right side of the mandrel mounting rod surface is set as a first inclined surface. The mounting hole is located in the middle of the mandrel, and the right side of the inner wall surface of the mounting hole is set as a second inclined surface. The first threaded hole is located at the right end of the mandrel mounting rod; The first through hole is located at the right end of the mandrel; The first bolt passes through the first through hole and connects to the first threaded hole; A fixed side plate is mounted on the fixed plate. The fixed side plate is provided in two sets, front and rear, and a first guide wheel and a second guide wheel are provided between the two sets of fixed side plates.

[0007] Preferably, a mounting shaft is provided in the middle of both the first guide wheel and the second guide wheel, and a bearing is provided between the first guide wheel, the second guide wheel and the mounting shaft.

[0008] Preferably, both ends of the mounting shaft are provided with second threaded holes, and second threaded bolts are provided in the second threaded holes.

[0011] Preferably, both one side of the inner wall of the sleeve and one side of the lifting rod are made into planes.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The first bolt passes through the first through hole and connects to the first threaded hole. Tightening the first bolt fixes the mandrel. The first inclined surface on the inner wall of the mounting hole cooperates with the second inclined surface on the mandrel mounting rod, so that during the fixing process, the center of the mandrel and the center of the mandrel mounting rod are on the same horizontal straight line, allowing the quartz tube to generate the mass of a spiral quartz tube by spirally rotating around the mandrel. The mandrel is then disassembled by loosening the first bolt and quickly removing it. This device can produce spiral quartz tubes of different outer diameters by changing mandrels of different diameters. It is suitable not only for mass production of spiral quartz tubes but also for small-batch production.

[0013] 2. The second guide wheel moves by sliding within the groove via the mounting shaft, changing the distance between the second guide wheel and the first guide wheel. After the second guide wheel is adjusted, the second bolt is tightened to fix the second guide wheel. The two ends of the mounting shaft cannot extend out of the groove and must remain inside the groove. The second bolt fixes the second guide wheel by fixing the mounting shaft, allowing quartz tubes of different sizes to pass through the first and second guide wheels. This device bends quartz tubes of different diameters. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-8This utility model provides a technical solution: a quartz tube production device with adjustable spiral quartz tube size, including a base 1, a mandrel 4, and an oxyhydrogen flame torch 81. A first adjustment mechanism 5 and a second adjustment mechanism 51 are provided on the top of the base 1. The first and second adjustment mechanisms 51 have the same structure. A support column 2 is fixedly installed on the top of the base 1, and a fixing plate 3 is fixedly installed on the top of the support column 2. The first adjustment mechanism 5 includes a sleeve 6 and a lifting rod 7. The lifting rod 7 is installed inside the sleeve 6, and a telescopic rod 8 is installed on the upper part of the lifting rod 7. An oxyhydrogen flame torch 80 is installed on the right end of the telescopic rod 8. The left end of the mandrel mounting rod 9 is fixedly installed on the support column 2. The right side of the surface of the mandrel mounting rod 9 is set as a first inclined surface 10. A mounting hole 41 is located in the middle of the mandrel 4, and the right side of the inner wall surface of the mounting hole 41 is set as a second inclined surface 11. A first threaded hole 12 is located on the right end of the mandrel mounting rod 9, and a first through hole 13 is located on the mandrel. 4. At the right end, the first bolt 14 passes through the first through hole 13 and connects to the first threaded hole 12 to install the mandrel 4. The mandrel 4 is then fitted onto the mandrel mounting rod 9, so that the first bolt 14 passes through the first through hole 13 and connects to the first threaded hole 12. The first bolt 14 is tightened to fix the mandrel 4. The first inclined surface on the inner wall of the mounting hole 41 cooperates with the second inclined surface 10 on the mandrel mounting rod 9, so that during the fixing process, the center of the mandrel 4 and the center of the mandrel mounting rod 9 are on the same horizontal straight line, so that the quartz tube rotates around the mandrel 4 to generate the mass of the spiral quartz tube. The mandrel 4 is then disassembled by loosening the first bolt 14 and quickly disassembling the mandrel 4. In the production of spiral quartz tubes with different outer diameters, the mandrels of different diameters are replaced. This device produces spiral quartz tubes with different outer diameters and is suitable not only for mass production of spiral quartz tubes but also for small-batch production of spiral quartz tubes. A fixed side plate 15 is mounted on a fixed plate 3. The fixed side plate 15 has two sets, front and rear, with a first guide wheel 17 and a second guide wheel 18 between the two sets of fixed side plates 15. A sliding groove 16 is located in the middle of the fixed side plate 15, and both sets of fixed side plates 15 are provided with sliding grooves 16. The quartz tube is heated by an oxyhydrogen flame torch 81 mounted on the first adjustment mechanism 5 and the second adjustment mechanism 51, through the first guide wheel 17 and the second guide wheel 18. The height of the oxyhydrogen flame torch 81 mounted on the second adjustment mechanism 51 is higher than that mounted on the first adjustment mechanism 5. The oxyhydrogen flame torch 81 mounted on the second adjustment mechanism 51 preheats the quartz tube first, and then the oxyhydrogen flame torch 81 mounted on the first adjustment mechanism 5 heats the quartz tube, causing the quartz tube to move in a spiral motion around the mandrel 4 to quickly reach a temperature suitable for bending in the production of spiral quartz products.

After the second guide wheel 18 is adjusted, the second bolt 22 is tightened to fix the second guide wheel 18. Both ends of the mounting shaft 19 cannot extend out of the groove 16 and remain inside the groove 16. The second bolt 22 fixes the second guide wheel 18 by fixing the mounting shaft 19, allowing quartz tubes of different sizes to pass through the first guide wheel 17 and the second guide wheel 18. This device can bend quartz tubes of different diameters.

[0019] Reference embodiment: The upper part of the lifting rod 7 is provided with a second through hole 71 that cooperates with the telescopic rod 8.

When the positioning rod 73 is moved upward, the positioning rod 73 disengages from the positioning hole 81, loosening the fixation on the telescopic rod 8. The telescopic rod 8 is moved to adjust the distance between the hydrogen-oxygen flame spray gun 81 and the core rod 4 at the right end of the telescopic rod 8. Reference embodiment: A third threaded hole 61 is provided on one side of the sleeve 6, and a third bolt 62 is provided in the third threaded hole 61. Loosening the third bolt 62 causes the lifting rod 7 to move up and down, adjusting the height of the telescopic rod 8 and the oxyhydrogen flame spray gun 81.
