Description

Technical Field

[0001] The present application relates to the technical field of basalt pipe forming, and specifically discloses a forming device for basalt pipe production. Background Art

[0002] Basalt fiber is a continuous fiber drawn from natural basalt. It is made by melting basalt at 1450℃-1500℃ and then drawing it at high speed through a platinum-rhodium alloy drawing plate. The color of pure natural basalt fiber is generally brown. Basalt fiber is a new type of inorganic, environmentally friendly, green, high-performance fiber material. It is composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide and titanium dioxide. Basalt continuous fiber not only has high strength, but also has many excellent properties such as electrical insulation, corrosion resistance and high temperature resistance.

[0003] Basalt pipe processing generally adopts external mold forming. After the mold forming is completed, due to the high heat in the mold, it is necessary to cool down. After cooling down, the excess part of the basalt pipe is cut. For example, a basalt fiber pipe forming device described in Chinese patent publication number CN217226075U includes a mounting frame, a cooling mechanism, which is arranged on the mounting frame, wherein: the cooling mechanism includes an inner cooling water pipe, one side of the outer surface of the mounting frame is fixedly connected to an inner column, the inner cooling water pipe is opened inside the inner column, and a grinding mechanism is arranged on the inner column, wherein: the grinding mechanism includes a driving component, a grinding frame and a grinding brush.

[0004] The device can cool the pipe, but during the molding process, the inner cooling pipe lacks a supporting structure. When the raw material is pressed into the molding device by pressure, the inner cooling pipe is offset, which leads to uneven molding of the basalt fiber pipe.

[0005] Therefore, in view of this, the inventor provides a forming device for basalt pipe production to solve the above problems. Utility Model Content

[0006] The utility model aims to solve the problem that the existing basalt pipe forming device lacks a supporting structure for forming an inner pipe, so that the basalt pipe is formed unevenly.

[0007] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a forming device for basalt pipe production, including an outer mold with a pressurized injection structure, an inner cooling pipe coaxially arranged in the outer mold and extending out of the outer mold at both ends, a forming chamber arranged between the outer mold and the inner cooling pipe, support members arranged at both ends of the outer mold for supporting the inner cooling pipe and a support frame for supporting the outer mold, a section of the inner cooling pipe extending out of the outer mold is provided with a cooling injection pipe for injecting a cooling airflow, the support members include an outer ring connected to the outer mold and a sealing plate arranged between the outer ring and the inner cooling pipe for closing the forming chamber, and a driving member for driving the inner cooling pipe to rotate is provided at one end of the inner cooling pipe.

[0008] Furthermore, a plurality of support rods are provided between the outer ring and the inner cooling tube, the support rods comprising a support portion and a sliding portion, both the support portion and the sliding portion are provided with adjustment holes, and the adjustment holes are provided with fixing members that can be inserted into the adjustment holes and are used to fix the extension length of the sliding portion.

[0009] Furthermore, the driving member is a servo motor, a protective shell is provided on the servo motor, a support plate is fixedly connected to the support frame, and the protective shell is detachably connected to the support plate. The servo motor is a stable driving member.

[0010] Furthermore, the output shaft of the servo motor is coaxially connected to the inner cooling tube, and the inner cooling tube is driven to rotate coaxially by the coaxial connection, so that the inner cooling tube is formed evenly.

[0011] Furthermore, the pressurized injection structure includes an injection pipe provided on the outer mold for injecting raw materials and a pressurized pipe for pressing the raw materials into the outer mold for molding, and the pressurized pipe is connected to a pressurizing member.

[0012] Furthermore, the pressurizing member is an air pump.

[0013] The principle and effect of this scheme are:

[0014] 1. Compared with the prior art, the utility model cooperates with the inner cooling tube, the outer mold and the driving member, and utilizes the sealing effect of the sealing plate and the supporting effect of the inner cooling tube. While the outer mold is being injected and pressurized, the inner cooling tube is driven to rotate, so that the inner cooling tube can evenly extrude the injected raw material, thereby making the basalt pipe forming more uniform. Through the supporting effect of the supporting member, the gap between the outer mold and the inner cooling tube is uniform, which prevents the inner cooling tube from lacking support during pressurized injection, resulting in uneven gap and affecting the quality of the pipe. This solves the problem that the existing molding device lacks a supporting structure for pipe forming, resulting in uneven basalt pipe forming.

[0015] 2. Inject cold air through the cooling pipe and use the conduction effect of the cooling pipe to cool the formed raw materials. At the same time, due to the continuous rotation of the inner cooling pipe, the basalt pipe is cooled more evenly, thereby improving the product quality.

[0016] 3. The gap between the inner cooling pipe and the outer mold can be adjusted by setting the support rod, so as to cooperate with the sealing plate to produce basalt pipes of different diameters. The support part can also assist the sealing plate in supporting the inner cooling pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] The figure marks in the drawings of the specification include: injection pipe 1, outer mold 2, support frame 3, outer ring 4, injection cooling pipe 5, inner cooling pipe 6, protective shell 7, support plate 8, sealing plate 9, pressurizing pipe 10, support rod 11, and air pump 12.

[0022] A forming device for producing basalt pipes, for example Figure 1As shown: it includes an outer mold 2 for pipeline injection molding, the left end of the outer mold 2 is connected to a pressurizing pipe 10, and the pressurizing pipe 10 is connected to a pressurizing member. In this embodiment, the pressurizing member is an air pump 12, and the air pump 12 and the pressurizing pipe 10 are used to pressurize and evenly press the raw material into the molding chamber between the outer mold 2 and the inner cooling pipe 6, so that the basalt pipeline is formed. The left top of the outer mold 2 is connected to an injection pipe 1, and the raw material falls through the injection pipe 1, and the pressurized airflow of the pressure pipe 10 makes the raw material flow, and cooperates with the rotating inner cooling pipe 6 to form. It also includes a support frame 3, on which an arc-shaped support member adapted to the outer mold 2 is fixedly welded, thereby supporting the outer mold 2. A support plate 8 is also fixedly welded on the right end of the support frame 3. In the present embodiment, a threaded hole is opened on the support plate 8, and the driving member is fixed to the support plate 8 by bolts. In the present embodiment, the driving member is a servo motor, and the servo motor is electrically connected to a controller to control the rotation of the inner cooling tube 6. A protective shell 7 is installed on the outside of the servo motor to protect the servo motor. The servo motor is coaxially arranged with the outer mold 2 and the inner cooling tube 6, and the output shaft of the servo motor is located at the center of the outer surface of the inner cooling tube 6, thereby ensuring uniform forming of the basalt pipe.

[0023] like Figure 2 As shown, an inner cooling pipe 6 is coaxially arranged inside the outer mold 2, and a section of the inner cooling pipe 6 extends out of the outer mold 2 on the right side and is connected to a cooling injection pipe 5. After the molding is completed, a refrigeration device is used to inject cold air into the inner cooling pipe 6 through the cooling injection pipe 5 to quickly cool the molded basalt pipe, and the rotation effect of the inner cooling pipe 6 is combined to make the basalt pipe evenly cooled during cooling.

[0024] Both ends of the inner cooling tube 6 extend out of the outer mold 2. Both ends of the outer mold 2 are equipped with support members for supporting the inner cooling tube 6. The support members include an outer ring 4 connected to the outer mold 2 and detachable, and a support rod 11 installed between the outer ring 4 and the inner cooling tube 6. A fixed sealing plate 9 is installed between adjacent support rods 11. The molding chamber is closed by the sealing plate 9. Preferably, a sealing ring is provided at the end of the sealing plate 9 to enhance the sealing effect and support the inner cooling tube 6 to prevent the inner cooling tube 6 from deviating during pressurized injection. The end of the right end of the inner cooling tube 6 is coaxially connected to the servo motor 7. Therefore, when the servo motor 7 rotates, the inner cooling tube 6 evenly rolls the raw material during rotation, so that the basalt pipe is formed more evenly. The support rod 11 includes a support part and a sliding part. The support part and the sliding part are both provided with adjustment holes. The adjustment hole is provided with a fixing member for fixing the extension length of the sliding part. In this embodiment, the fixing member is a bayonet pin, which is fixed by sliding the sliding part. Preferably, the end of the support part is an arc block that is attached to the outer wall of the inner cooling tube 6, so as to facilitate the rotation of the inner cooling tube 6 and prevent the position of the inner cooling tube 6 from being offset, so that the thickness of the formed basalt pipe is uniform and the position of the inner cooling tube 6 is prevented from being offset when pressurized. After forming, the two ends of the basalt pipe that are attached to the sealing plate 9 are cut to obtain a finished basalt pipe.

[0025] The use process of the utility model is as follows: first, the positions of the inner cooling tube 6 and the outer mold 2 are fixed by the support, and the material is injected through the pressure tube 10 and the injection tube 1, and the inner cooling tube 6 is driven to rotate, so that the raw materials are rolled evenly before the basalt pipe is formed. After the forming is completed, cold air is injected into the inner cooling tube 6, and it is continuously rotated, so that the cooling is uniform and the cooling rate is accelerated, thereby improving the product quality. After cooling and forming, the excess part is cut to obtain a uniform and high-quality basalt pipe.

[0026] The utility model solves the problem that the existing forming device lacks a supporting structure for forming the pipeline, resulting in uneven forming of the basalt pipeline.

[0027] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
