Description

Technical Field

[0001] The present invention relates to a preparation process, in particular to a preparation process of a quartz tube applied to the field of quartz tube production. Background Art

[0002] A quartz tube is a transparent or semi-transparent tubular product made of high-purity quartz material, having a series of excellent physical and chemical properties, and is widely used in various industrial and scientific fields.

[0003] When the quartz tube is formed, the molten quartz liquid is introduced into a mold for cooling and solidification, and then the mold is opened to take out the quartz tube. This method of forming through a single mold cannot be applied to quartz tubes of different shapes, such as arc-shaped quartz tubes. When the arc length of the quartz tube needs to be changed, it is necessary to replace the corresponding mold or perform cutting after forming, which brings great inconvenience to production. Therefore, further improvement is needed. Summary of the Invention

[0004] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is that the method of forming through a single mold cannot be applied to quartz tubes with different arc lengths.

[0005] To solve the above problems, the present invention provides a preparation process of a quartz tube. The preparation process involves an arbitrary molding machine. The arbitrary molding machine includes a fixed disk and a moving disk. An outer arc cooling plate and an inner arc cooling plate are rotatably connected between the fixed disk and the moving disk. The inner arc cooling plate is located inside the outer arc cooling plate. A molding cavity is arranged between the outer arc cooling plate and the inner arc cooling plate. A feed pipe is fixedly connected to the top end of the outer arc cooling plate, and the feed pipe is communicated with the molding cavity. A bottom plug plate is slidably connected between the bottom ends of the outer arc cooling plate and the inner arc cooling plate. One end of the outer arc cooling plate close to the bottom plug plate is fixedly connected with an opening and closing electric rod, and the telescopic end of the opening and closing electric rod is fixedly connected with one end of the bottom plug plate. Two sliding grooves are respectively opened at one ends of the fixed disk and the moving disk close to each other. Sliding bars matching the sliding grooves are fixedly connected to both ends of the outer arc cooling plate and the inner arc cooling plate. The sliding bars are located inside the sliding grooves and are slidably connected with the sliding grooves. A plurality of clamping blocks are slidably connected through the side walls of the fixed disk and the moving disk. A plurality of clamping electric rods are fixedly connected to one ends of the fixed disk and the moving disk away from each other. The plurality of clamping electric rods correspond to the plurality of clamping blocks one by one, and the telescopic ends of the clamping electric rods are fixedly connected with one ends of the clamping blocks. The outer arc cooling plate and the inner arc cooling plate are one-fourth of a whole circle. The horizontal part of the molding cavity is set as a horizontal layer, and the lower part of the molding cavity located in the horizontal layer is set as a solidification area, and one-third of the lower part of the solidification area is set as a withdrawal area.

[0006] The preparation process of the quartz tube includes the following steps:

[0007] S1. Drive the bottom plug plate to move towards the inner arc cooling plate through the opening and closing electric rod to block the bottom end of the solidification area;

[0008] S2. Inject the quartz tube melt into the interior of the forming cavity through the feed pipe, and the quartz tube melt is located inside the solidification zone, and the top surface of the quartz tube melt is at the position of the horizontal layer;

[0012] As a further improvement of the present application, the preparation process of the quartz tube further includes the following steps:

[0013] S6. When a complete quartz tube needs to be manufactured, one end of the quartz tube blank rotates to the interior of the top end of the forming cavity, and then the quartz tube melt is injected through the feed pipe to connect the head end and the tail end of the quartz tube blank to form a complete quartz tube.

[0014] As a further improvement of the present application, any forming machine further includes a bottom plate, the side wall on one side of the outer arc cooling plate is fixedly connected to the bottom plate through an outer connecting rod, a through groove is formed through the side wall of the fixed disk, the side wall on one side of the inner arc cooling plate is fixedly connected to the bottom plate through an inner connecting rod, and the inner connecting rod passes through the through groove.

The top surface of the quartz tube melt is at the position of the horizontal layer. The quartz tube melt inside the solidification zone is cooled and solidified to form a quartz tube blank.

[0029] The following will describe in detail two implementation manners of the present application with reference to the accompanying drawings.

[0030] The first implementation manner:

[0031] Figures 1-9 A preparation process of a quartz tube is shown. This preparation process involves an arbitrary molding machine. The arbitrary molding machine includes a fixed disk 1 and a movable disk 2. An outer arc cooling plate 3 and an inner arc cooling plate 4 are rotatably connected between the fixed disk 1 and the movable disk 2. The inner arc cooling plate 4 is located inside the outer arc cooling plate 3. A molding cavity 5 is arranged between the outer arc cooling plate 3 and the inner arc cooling plate 4. The top end of the outer arc cooling plate 3 is fixedly connected with a feed pipe 6, and the feed pipe 6 is communicated with the molding cavity 5. A bottom plug plate 7 is slidably connected between the bottom ends of the outer arc cooling plate 3 and the inner arc cooling plate 4. One end of the outer arc cooling plate 3 close to the bottom plug plate 7 is fixedly connected with an opening and closing electric rod 701, and the telescopic end of the opening and closing electric rod 701 is fixedly connected with one end of the bottom plug plate 7. Two slide grooves 8 are opened at one end of the fixed disk 1 and the movable disk 2 close to each other. Slide bars 9 matching the slide grooves 8 are fixedly connected to both ends of the outer arc cooling plate 3 and the inner arc cooling plate 4. The slide bars 9 are located inside the slide grooves 8 and the slide bars 9 are slidably connected with the slide grooves 8. A plurality of clamping blocks 10 are slidably penetrated through the side walls of the fixed disk 1 and the movable disk 2. A plurality of clamping electric rods 11 are fixedly connected to one end of the fixed disk 1 and the movable disk 2 away from each other. The plurality of clamping electric rods 11 correspond to the plurality of clamping blocks 10 one by one, and the telescopic end of the clamping electric rod 11 is fixedly connected with one end of the clamping block 10. The outer arc cooling plate 3 and the inner arc cooling plate 4 are one-fourth of a whole circle. The horizontal part of the molding cavity 5 is set as a horizontal layer 501, and the lower part of the molding cavity 5 located at the horizontal layer 501 is set as a solidification zone 502. The lower one-third of the solidification zone 502 is set as an extraction zone 5021.

[0032] The preparation process of the quartz tube includes the following steps:

[0033] S1. Drive the bottom plug plate 7 to move towards the inner arc cooling plate 4 through the opening and closing electric rod 701 to block the bottom end of the solidification zone 502;

[0034] S2. Inject the fused quartz tube solution into the interior of the forming cavity 5 through the feed pipe 6, and the fused quartz tube solution is located inside the solidification zone 502, and the top surface of the fused quartz tube solution is at the position of the horizontal layer 501;

[0035] S3. Cool and solidify the fused quartz tube solution inside the solidification zone 502 to form a quartz tube blank;

[0036] S4. Start the opening and closing rod 701 to drive the bottom plug plate 7 to move towards the outer arc cooling plate 3, open the bottom end of the solidification zone 502, start the clamping rod 11 to clamp the quartz tube blank through the clamping block 10, and rotate the fixed disk 1 and the moving disk 2 counterclockwise to move the top end of the quartz tube blank to be flush with the top surface of the extraction zone 5021;

[0037] S5. Repeat the steps of S2 - S4 to manufacture quartz arc tubes of different specifications;

[0038] S6. When a complete quartz tube needs to be manufactured, one end of the quartz tube blank is rotated into the interior of the top end of the forming cavity 5, and then the fused quartz tube solution is injected through the feed pipe 6 to connect the head and tail ends of the quartz tube blank to form a complete quartz tube.

[0039] In this preparation process, when manufacturing quartz tubes with different arc lengths, there is no need to replace different types of molds, which reduces the manufacturing cost, or omits the cutting process, improving the manufacturing efficiency.

[0040] The second implementation method:

[0041] Figures 2-5 A preparation process of a quartz tube is shown. Different from the first implementation method, any molding machine further includes a bottom plate 12. The side wall on one side of the outer arc cooling plate 3 is fixedly connected to the bottom plate 12 through an outer connecting rod 13. A through groove 101 is formed through the side wall of the fixed disk 1. The side wall on one side of the inner arc cooling plate 4 is fixedly connected to the bottom plate 12 through an inner connecting rod 14, and the inner connecting rod 14 passes through the through groove 101. One end of the bottom plate 12 close to the fixed disk 1 is fixedly connected to a front vertical plate 15. One end of the front vertical plate 15 is fixedly connected to a front rotating motor 16. The output end of the front rotating motor 16 is fixedly connected to the center of the fixed disk 1. One end of the bottom plate 12 close to the moving disk 2 is fixedly connected to a rear vertical plate 17. One end of the rear vertical plate 17 is fixedly connected to a rear rotating motor 18. The output end of the rear rotating motor 18 is fixedly connected to a blanking rod 19. The telescopic end of the blanking rod 19 is fixedly connected to the middle of the moving disk 2.

[0042] Through the above settings, when starting the clamping rod 11 to clamp the quartz tube blank through the clamping block 10 and rotating the fixed disk 1 and the moving disk 2 counterclockwise, the front rotating motor 16 and the rear rotating motor 18 can be started to drive the fixed disk 1 and the moving disk 2 to rotate counterclockwise. After the quartz tube is formed, the blanking rod 19 drives the moving disk 2 to move away from the fixed disk 1 to remove the quartz tube from the forming cavity 5.

[0043] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
