Description

Technical Field

[0001] This utility model relates to the field of quartz crucible production technology, specifically to a limiting device for scraping and forming quartz crucibles. Background Technology

[0002] The production process of quartz crucibles is as follows: Selected quartz powder is loaded into a rotating mold, and the crucible is manually shaped using centrifugal force and a scraping forming rod. The rotating device, which has already formed a crucible shape, is moved to the electrode rod. Then, the electrode is energized to start the arc and inserted into the shaped quartz cavity. At the same time, the vacuum system is started to quickly melt it into molten quartz in the shape of a crucible. After cooling, the crucible is taken out, the arc is turned off, the mold is knocked to demold the crucible, and finally, sandblasting is performed.

[0003] The current technical defect is that during the process of adding material while the rotary mold is rotating, it is necessary to manually insert the scraper forming rod into the rotary mold to scrape the material and control the thickness of the material layer. The worker usually uses one hand to load the material and the other hand to fix the scraper forming rod. The loading needs to be repeated many times, so the scraper forming rod needs to be fixed again after each loading. This results in inconsistent material layer thickness, which affects the product quality of the quartz crucible. Utility Model Content

[0004] The purpose of this invention is to provide a limiting device for scraping and forming quartz crucibles.

[0005] This utility model is implemented by the following technical solution: A limiting device for scraping and forming quartz crucibles includes a rotating mold rotatably mounted on a platform. A telescopic rod is fixed to the upper surface of one side of the platform, and a horizontal adjustment mechanism is fixed to the top of the telescopic rod. The horizontal adjustment mechanism includes a connecting plate and an adjusting plate. The connecting plate is fixed to the top of the telescopic rod and has a first threaded through hole. The adjusting plate has a waist groove and a U-shaped slot. A bolt passes through the waist groove and the first threaded through hole to connect and fix the connecting plate. A positioning groove is provided at the center of the bottom surface of the rotating mold, and the scraping forming rod is engaged between the positioning groove and the U-shaped slot.

[0006] Preferably, the scraping forming rod includes a vertical rod, an arc-shaped rod, and a positioning cone, which are fixedly connected in sequence; the vertical rod is engaged in a U-shaped groove, and the positioning cone is inserted into a positioning groove.

[0007] Preferably, the telescopic rod is equipped with a clamping wrench for adjusting the telescopic height. The telescopic rod includes a first vertical rod and a second vertical rod that is movably inserted inside the first vertical rod and located above it.

The stud and the second threaded through hole are threadedly connected and abut against the surface of the second vertical rod. A limit ring is fixed on the outer side of the middle part of the second vertical rod. The limit ring is located above the top of the first vertical rod.

[0008] The advantages of this invention are: compared with scraping material with a handheld scraping rod, it avoids the process of repeatedly fixing the scraping rod, resulting in a consistent material layer thickness and improving the product quality of the quartz crucible.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0012] like Figures 1 to 5As shown, a limiting device for scraping and forming quartz crucibles includes a rotating mold 1, which is rotatably mounted on a platform 2. A telescopic rod 3 is fixed to the upper surface of one side of the platform 2. A clamping wrench 7 for adjusting the telescopic height is installed on the telescopic rod 3. The telescopic rod 3 includes a first vertical rod 3.1 and a second vertical rod 3.2 that is movably inserted into and above the first vertical rod 3.1. A second threaded through hole 3.11 is opened on one side of the first vertical rod 3.1. A stud 8 is fixed on the clamping wrench 7. The stud 8 is threadedly connected to the second threaded through hole 3.11 and abuts against the surface of the second vertical rod 3.2. A limiting ring 3.21 is fixed to the outer side of the middle part of the second vertical rod 3.2. The limiting ring 3.21 is located above the top of the first vertical rod 3.1.

[0013] A horizontal adjustment mechanism 4 is fixed to the top of the telescopic rod 3; the horizontal adjustment mechanism 4 includes a connecting plate 4.1 and an adjusting plate 4.2. The connecting plate 4.1 is fixed to the top of the telescopic rod 3. A first threaded through hole 4.11 is provided on the connecting plate 4.1. A waist groove 4.21 and a U-shaped slot 4.22 are provided on the adjusting plate 4.2. Bolts 5 pass through the waist groove 4.21 and the first threaded through hole 4.11 and are threaded to connect and fix the connecting plate 4.1. A positioning groove 1.1 is provided at the center of the bottom surface inside the rotating mold 1; the scraper forming rod 6 is in In actual use, there are multiple models, each corresponding to a different forming thickness. The scraping forming rod 6 includes a vertical rod 6.1, an arc-shaped rod 6.2, and a positioning cone 6.3, which are fixedly connected in sequence. The vertical rod 6.1 is engaged in the U-shaped groove 4.22, and the positioning cone 6.3 is inserted into the positioning groove 1.1, so that the scraping forming rod 6 is engaged between the positioning groove 1.1 and the U-shaped groove 4.22 and remains fixed, and will not rotate with the rotating mold 1. That is, when the rotating mold 1 is rotating, the scraping forming rod 6 can perform forming scraping.

[0014] Working process: First, place the adjusting plate 4.2 above the rotating mold 1. Then, fix the scraper forming rod 6 between the positioning groove 1.1 and the U-shaped groove 4.22 so that the surface of the scraper forming rod 6 and the inner wall of the rotating mold 1 maintain the same distance, ensuring that the thickness of the scraped forming material layer is basically equal. The rotating mold 1 is loaded with quartz powder while rotating. During the rotation of the rotating mold 1, the material layer is scraped by the scraper forming rod 6 to form a flat and smooth inner wall of the quartz crucible.

[0015] After scraping is completed, remove the scraping forming rod 6 and adjust the adjusting plate 4.2 to be positioned below the upper end face of the rotating mold 1 to protect the device from burning or deformation during the heating process.
