Technical Field:

[0001] The utility model relates to the technical field of quartz crucible forming equipment, and particularly relates to a scraping and forming device for adjusting the wall thickness of a quartz crucible. Background Art:

[0002] The production process of a quartz crucible is as follows: quartz powder is loaded into a rotary forming die that can be tilted at any angle, and it is manually formed by the action of centrifugal force and a scraping and forming rod. The rotating device with the already formed crucible shape is moved to the electrode rod, then the electrode is powered on to start an arc and inserted into the formed powder cavity. At the same time, the vacuum system is started to quickly melt it into molten quartz in the shape of a crucible, and it is taken out after cooling.

[0003] Currently, different wall thickness quartz crucibles are made by using scraping and forming rods of different sizes.

[0018] As Figures 1 - 5 shown, a scraping and forming device for adjusting the wall thickness of a quartz crucible includes a scraping and forming rod 1, a fixing block 2, a screw 3, a first nut 4, and a second nut 5;

[0019] The scraping and forming rod 1 includes a vertical rod 1.1 and an arc rod 1.2, which are integrally formed. The main function of the scraping and forming rod 1 is to scrape materials. The vertical rod 1.1 scrapes materials on the side wall of the forming die 8 to form a flat and smooth inner side wall of the quartz crucible. The arc rod 1.2 scrapes materials on the bottom wall of the forming die 8 to form a flat and smooth inner bottom wall of the quartz crucible. A handle 6 is fixed at the top end of the vertical rod 1.1 for convenient operation by the operator;

[0020] A fixing block 2 is horizontally connected to the end of the arc rod 1.2 of the scraping and forming rod 1. A strip hole 2.1 is vertically and movably penetrated through the top surface of the fixing block 2 in the length direction. A screw 3 is vertically and movably penetrated through the strip hole 2.1. A first nut 4 is screwed onto the screw 3 above the fixing block 2, and the bottom surface of the first nut 4 abuts against the top surface of the fixing block 2. A second nut 5 is screwed onto the screw 3 below the fixing block 2, and the top surface of the second nut 5 abuts against the bottom surface of the fixing block 2. By screwing the first nut 4 and the second nut 5 to tighten the fixing block 2, the screw 3 can be vertically fixed in the strip hole 2.1 of the fixing block 2; when it is necessary to adjust the side wall thickness of the quartz crucible, the first nut 4 and the second nut 5 are screwed to loosen the fixing block 2, so that the scraping and forming rod 1 and the fixing block 2 move horizontally relative to the screw 3, adjusting the horizontal distance between the vertical rod 1.1 of the scraping and forming rod 1 and the inner side wall of the forming die 8, changing the thickness of the scraping layer, thereby achieving the purpose of adjusting the side wall thickness of the quartz crucible; when it is necessary to adjust the bottom wall thickness of the quartz crucible, the first nut 4 and the second nut 5 are screwed to loosen the fixing block 2, so that the scraping and forming rod 1 and the fixing block 2 move vertically up and down relative to the screw 3, adjusting the longitudinal distance between the arc rod 1.2 of the scraping and forming rod 1 and the bottom of the forming die 8, thereby achieving the purpose of adjusting the bottom wall thickness of the quartz crucible; a scale line 7 is marked on the side surface of the fixing block 2 along the length direction of the strip hole 2.1, and the horizontal moving distance of the fixing block 2 relative to the screw 3 can be accurately measured through the scale line 7.

[0021] Working process: As Figure 5As shown in the figure, place the scraping and forming device in the rotatable forming mold 8. Load quartz powder into the forming mold 8. Vertically insert the tip of the screw 3 into the quartz powder at the center of the bottom of the forming mold 8. The operator holds the handle 6 of the scraping and forming rod 1 still and rotates the forming mold 8. The vertical rod 1.1 of the scraping and forming rod 1 scrapes on the side wall of the forming mold 8 to form a flat and smooth inner side wall of the quartz crucible. The arc-shaped rod 1.2 of the scraping and forming rod 1 scrapes on the bottom wall of the forming mold 8 to form a flat and smooth inner bottom wall of the quartz crucible. When it is necessary to adjust the wall thickness of the quartz crucible, taking thickening as an example: Unscrew the first nut 4 and the second nut 5 to loosen the fixing block 2, so that the scraping and forming rod 1 and the fixing block 2 move upward along the vertical direction relative to the screw 3. At this time, the longitudinal distance between the arc-shaped rod 1.2 and the bottom wall of the forming mold 8 becomes larger. At the same time, make the scraping and forming rod 1 and the fixing block 2 move inward toward the inside of the forming mold 8 along the horizontal direction relative to the screw 3. At this time, the transverse distance between the vertical rod 1.1 and the inner side wall of the forming mold 8 becomes larger. Then screw the first nut 4 and the second nut 5 again to tighten the fixing block 2, and rotate the forming mold 8. The thickness of the scraping layer becomes larger, and the overall wall thickness of the produced quartz crucible becomes thicker.

[0022] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
