Description

TECHNICAL FIELD

[0001] The utility model belongs to silicon carbon composite material technical field, more particularly to a kind of silicon carbon composite material setting device for furnace eye repair. BACKGROUND

[0002] In industrial manufacturing, furnace eye is the passage of high-temperature melt from the furnace, because it is often eroded by high-temperature furnace gas and high-temperature furnace slag, and needs to be maintained and repaired regularly. Carbon-silicon composite material is a composite material composed of carbon and silicon. This material is very suitable for repairing furnace eye due to its high strength, high hardness, wear resistance, high temperature resistance and oxidation resistance.

[0003] The existing patent with publication number CN217621907U discloses a high molecular material injection molding setting device, which is provided with a rocking lever, a turntable, a worm, a worm wheel, a second threaded rod, a threaded block, a mounting block, a clamping block, a positioning mold base, a servo motor, an injection cover plate, an injection pipe, etc. When in use, the worker rotates the rocking lever to drive the turntable to rotate. The rotation of the turntable will drive the second threaded rod to rotate under the cooperation of the worm and the worm wheel. The second threaded rod drives the threaded block to move downward, thereby driving the two mounting blocks to move away from each other, so that the two clamping blocks are clamped inside the setting mold base, and the positioning of the setting mold base is completed. Then the worker drives the injection cover plate to move downward by the servo motor, so that it covers the top of the setting mold base and injects material into the setting mold base through the injection pipe, thereby realizing the setting treatment of the composite material.

DETAILED DESCRIPTION

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Example 1: As Figs. 1-3 As shown, the technical solution adopted by this utility model is as follows: A silicon-carbon composite material shaping device for furnace hole repair includes a base 1 and a transmission assembly. A vertical support plate 2 is fixedly mounted on the top of the base 1, and a cylinder 3 is fixedly mounted on the top of the support plate 2. The telescopic shaft of the cylinder 3 slides through the support plate 2 and is fixedly connected to an injection molding cover plate 4. An injection molding hose 5 is slidably arranged on the support plate 2, and the bottom of the injection molding hose 5 is fixedly extended into the injection molding cover plate 4.

[0027] The top of the base 1 is both fixedly fitted with a positioning strip 15 and slidably fitted with an injection mold 16, which is located below the injection cover plate 4. The top of the injection mold 16 has an injection cavity, and the bottom of the injection mold 16 has a limiting groove adapted to the positioning strip 15, allowing for a slidable and limiting fit between the injection mold 16 and the positioning strip 15. Additionally, a positioning block 17 is fixedly fitted to the top of the base 1. The positioning strip 15 guides the injection mold 16, and the positioning block 17 limits the position of the injection mold 16.

[0028] The top of the base 1 is equipped with a limiting component, which is in transmission engagement with the injection molded cover plate 4 via a transmission component. The transmission component includes a bidirectional lead screw 11, which is rotatably mounted horizontally inside the base 1. Both ends of the bidirectional lead screw 11 extend rotatably to the outside of the base 1, and a first gear 10 is coaxially fixed at both ends of the bidirectional lead screw 11. Two connecting blocks 6 are fixedly mounted on the outer surface of the injection molded cover plate 4, located on opposite sides of the injection molded cover plate 4. A connecting shaft 7 is fixedly mounted vertically at the bottom of each connecting block 6, and a first rack 8 is fixedly mounted at the bottom of each connecting shaft 7. The first gear 10 corresponds one-to-one with the first rack 8, and each first gear 10 meshes with and remains meshed with the corresponding first rack 8. In addition, two limiting sleeves 9 are fixedly mounted vertically on the top of the base 1, and each limiting sleeve 9 corresponds one-to-one with the two connecting shafts 7. Each limiting sleeve 9 is in a limiting sliding engagement with the corresponding connecting shaft 7.

[0029] Start the air cylinder 3, control the extension of the telescopic shaft of the air cylinder 3, the telescopic shaft of the air cylinder 3 will push the injection cover plate 4 to move down, the injection cover plate 4 will move down to drive the two connecting shafts 7 to slide down under the limiting of the corresponding limiting sleeves 9 through the two connecting blocks 6, so as to drive the two first racks 8 to slide down, and the first rack 8 will drive the bidirectional screw rod 11 to rotate through the first gear 10. In this process, the injection hose 5 will also move down synchronously with the injection cover plate 4.

[0030] The limiting assembly comprises a clamping block 12, and two first sliding grooves 13 are formed in the top of the base 1, the two first sliding grooves 13 are symmetrical about the positioning strip 15, and one L-shaped clamping block 12 is limitingly and slidably arranged in each of the two first sliding grooves 13, and the two clamping blocks 12 slide towards or away from each other. The two clamping blocks 12 correspond to the two threaded segments of the bidirectional screw rod 11 in a one-to-one manner, and each clamping block 12 is in threaded connection with the corresponding threaded segment.

[0031] Two clamping grooves 14 are symmetrically formed in the bottom of the injection mold 16, and the two clamping grooves 14 correspond to the two first sliding grooves 13 and the two clamping blocks 12 in a one-to-one manner. Each clamping groove 14 is in sliding communication with the corresponding first sliding groove 13 and is in sliding clamping connection with the corresponding clamping block 12.

[0032] The rotation of the bidirectional screw rod 11 drives the two clamping blocks 12 to slide in the respective first sliding grooves 13, so that the two clamping blocks 12 move away from each other and are clamped in the respective corresponding clamping grooves 14, thereby limiting the injection mold 16.

[0033] In addition, it should be noted that the staff will enlarge the gap to be repaired of the furnace eye to a size suitable for the injection cavity of the injection mold 16 in advance when repairing the furnace eye. The silicon-carbon composite material in a molten state is delivered into the injection cavity through the injection hose 5 to complete the shaping, and then the shaped silicon-carbon composite material is adhered to the gap of the furnace eye through the adhesive to complete the repair.

[0034] The working principle of the first embodiment is as follows: when in use, the injection mold 16 is placed on the top of the base 1, and the injection mold 16 is pushed to slide under the limitation of the positioning strip 15 until the injection mold 16 abuts against the positioning block 17, at this time, the injection mold 16 is just located directly below the injection cover plate 4.

[0035] Start the air cylinder 3, control the extension of the telescopic shaft of the air cylinder 3, the telescopic shaft of the air cylinder 3 will push the injection cover plate 4 to move down, until the bottom of the injection cover plate 4 contacts the top of the injection mold 16. The injection cover plate 4 will move down to drive the two connecting shafts 7 to slide down under the limiting of the corresponding limiting sleeves 9 through the two connecting blocks 6, so as to drive the two first racks 8 to slide down. In this process, the injection hose 5 will also move down synchronously with the injection cover plate 4.

[0036] The downward sliding of the first rack 8 will drive the bidirectional lead screw 11 to rotate through the first gear 10. The rotation of the bidirectional lead screw 11 will cause the two locking blocks 12 to slide in their respective first sliding grooves 13, so that the two locking blocks 12 move away from each other and are locked in their respective corresponding slots 14, thus completing the limiting of the injection mold 16.

[0037] When the two locking blocks 12 are just engaged, the bottom of the injection cover plate 4 also comes into contact with the top of the injection mold 16, thus blocking and sealing the top of the injection cavity. Subsequently, the repair composite material is discharged into the injection mold 16 through the injection hose 5 for shaping.

[0038] After the shaping is complete, the telescopic shaft of the control cylinder 3 retracts, causing the injection molded cover plate 4 to move upward. This, through transmission, causes the two locking blocks 12 to move closer together, disengaging them from the locking slots 14 and releasing the locking blocks 12 from limiting the injection mold 16. Finally, the shaped repair composite material can be removed.

[0039] It should be noted that when repairing the furnace hole, the workers first enlarge the gap to be repaired to a size that matches the injection cavity of the injection mold 16. The molten silicon-carbon composite material is then transported into the injection cavity through the injection hose 5 to complete the shaping. Finally, the shaped silicon-carbon composite material is bonded to the gap in the furnace hole with an adhesive to complete the repair work.

[0040] Example 2: Figs. 4-6 As shown, the difference between this second embodiment and the first embodiment is that the limiting component includes a limiting frame 18, a second sliding groove 22 is opened on the top of the base 1, and a clearance groove is opened inside the base 1, which communicates with the second sliding groove 22. The limiting frame 18 is slidably set on the top of the base 1, and the bottom of the limiting frame 18 is slidably set in the second sliding groove 22. A second rack 19 is fixedly set on the bottom of the limiting frame 18, and the second rack 19 is located in the clearance groove. A limiting plate 21 is fixedly set on the top of the base 1, and the limiting frame 18 and the limiting plate 21 are arranged facing each other. The space enclosed by the limiting frame 18 and the limiting plate 21 after they abut against each other is located directly below the injection cover plate 4 and is used to limit and fix the injection mold 16.

[0041] The transmission assembly includes a rotating shaft 23, which is rotatably mounted horizontally within the base 1. Both ends of the rotating shaft 23 extend rotatably to the outside of the base 1 and are coaxially fixedly mounted with a third gear 24. The number of third gears 24 is equal to that of the first racks 8, and they correspond one-to-one. Each third gear 24 meshes with and is always engaged with the corresponding first rack 8. Simultaneously, a second gear 20 is fixedly fitted onto the outer surface of the rotating shaft 23, and the second gear 20 meshes with the second rack 19.

[0042] Working principle of the embodiment two: in use, the injection mold 16 is placed in the limiting frame 18, and the air cylinder 3 is started. The telescopic shaft of the air cylinder 3 drives the injection cover plate 4 to move downward until the bottom of the injection cover plate 4 contacts the top of the injection mold 16. The downward movement of the injection cover plate 4 drives the two connecting shafts 7 to slide downward through the two connecting blocks 6, thereby driving the two first racks 8 to slide downward. In this process, the injection hose 5 also synchronously moves downward with the injection cover plate 4 to stretch.

[0043] The downward sliding of the first rack 8 drives the rotation of the second gear 20 through the rotation of the rotating shaft 23 driven by the third gear 24, thereby driving the limiting frame 18 and the injection mold 16 to slide toward the limiting plate 21 through the second rack 19.

[0044] The limiting frame 18 slides and contacts the limiting plate 21, and the injection mold 16 is fixed after the contact. When the limiting frame 18 contacts the limiting plate 21, the injection mold 16 is just located below the injection cover plate 4, and the bottom of the injection cover plate 4 also contacts the top of the injection mold 16. Then, the repair composite material is discharged into the injection mold 16 through the injection hose 5 to be shaped.

[0045] After the shaping is completed, the telescopic shaft of the air cylinder 3 is retracted, the telescopic shaft of the air cylinder 3 drives the injection cover plate 4 to move upward, thereby driving the limiting frame 18 to slide away from the limiting plate 21 through the transmission, and thereby releasing the limiting of the injection mold 16.

[0046] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
