Description

Technical Field

[0001] This utility model relates to the field of zirconia fiberboard production equipment technology, specifically to a flipping device for zirconia fiberboard production. Background Technology

[0002] The information disclosed in the background section of this utility model is intended only to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0003] Zirconia fiberboard, as a high-performance ceramic material, is widely used in high-temperature insulation, aerospace, nuclear industry, and other fields. Its production process typically includes key steps such as raw material preparation, wet forming, pre-firing, pressing, high-temperature sintering, and post-treatment. In the pressing stage, the pre-fired fiber preform needs to be pressurized to improve its density and mechanical properties; this process is crucial to the quality of the preform.

[0004] In the production of zirconia fiberboard, the formed zirconia fiber blanks are placed on pallets and pre-fired before entering the forming section. Before forming, the bottom pallet must be removed and replaced with a flat forming plate (such as a graphite plate or a high-temperature resistant alloy plate) to ensure uniform pressure transmission and avoid interference from the pallet structure. Traditionally, operations rely on manual labor or simple equipment (such as overhead cranes or manual forklifts) to complete the blank flipping, pallet disassembly, and forming plate installation.

[0005] However, in existing technologies, the operation steps are cumbersome, and a single change takes as long as 10-15 minutes, which seriously restricts continuous production and leads to low efficiency. Moreover, during the flipping process, the billet (especially large-sized or thin-walled structures) is prone to cracks or deformation due to uneven stress, resulting in a high risk of billet damage. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a flipping device for the production of zirconia fiberboard.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A flipping device for the production of zirconia fiberboard includes a chassis, columns on the left and right sides of the center of the chassis, a flipping frame rotatably mounted on the columns, and a support frame for limiting the position of the flipping frame on one side below the flipping frame.

[0009] The flipping frame has a fixed clamp on one side of the front and rear sides for holding and fixing the zirconia fiber blank. The zirconia fiber blank is placed on a tray on the flipping frame at the bottom and a forming plate is placed on the top side. The zirconia fiber blank is held and fixed by a movable clamp on the other side.

[0010] Preferably, the fixed clip is detachably installed and fixed on the flipping frame via a movable base and threaded fastener.

[0011] Preferably, the flipping frame is provided with a crossbeam for clamping in conjunction with the movable clamp.

[0012] Preferably, the tilting frame is provided with a rotating shaft on the left and right sides, and the column is provided with a rotating hole that matches the rotating shaft.

[0013] Preferably, the support frame includes two support columns, and the flipping frame is provided with a limiting block adapted to the support frame.

[0014] Preferably, the limiting block is movably fixed to the top of the support column by a limiting fixing member.

[0015] Preferably, the chassis is provided with wheels and a base for support and leveling.

[0016] Preferably, the adjusting end of the fixed clip faces downwards, and the adjusting end of the movable clip faces upwards.

[0017] Preferably, the top of the column is provided with a hanging groove for accommodating a fixed clip.

[0018] This utility model has at least the following beneficial effects:

[0019] This invention can significantly reduce the time required for changing pallets and installing forming plates in traditional operations, which helps to achieve continuous production and thus significantly improves production efficiency.

[0020] Meanwhile, the combination of the forming plate and the tray ensures that the zirconia fiber preform is subjected to uniform force during the flipping process, avoiding cracks or deformation caused by improper manual or simple instrument operation, and reducing the risk of preform damage.

Detailed Implementation

[0024] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Figures 1 to 2 A flipping device for the production of zirconia fiberboard is presented, including a chassis 100. Columns 200 are arranged on the left and right sides of the center of the chassis 100. A flipping frame 300 is rotatably mounted on the columns 200. Specifically, rotating shafts 330 are arranged on the left and right sides of the flipping frame 300, and rotating holes adapted to the rotating shafts 330 are provided on the columns 200. A support frame 400 for limiting the flipping frame 300 is provided below one side of the flipping frame 300. The support frame 400 needs to provide space for the flipping frame 300 to flip, but should not interfere with the flipping frame 300's flipping. In this embodiment, the support frame 400 includes two support columns, and the flipping frame 300 is provided with a limiting block 320 adapted to the support frame 400.

[0026] The flipping frame 300 has a fixed clamp 500 on one of its front and rear sides for holding and fixing the zirconia fiber blank 900. The zirconia fiber blank 900 has a tray 700 placed on the flipping frame 300 below it and a forming plate 800 placed on top. The other side is held and fixed by a movable clamp 600. The flipping frame 300 is provided with a crossbeam 310 for cooperating with the movable clamp 600 for clamping. The fixed clamp 500 and the movable clamp 600 are shown in the attached figures. The clamps themselves are not a design focus of this application; they can be easily implemented using existing technology and will not be elaborated upon here.

[0027] During operation, the pallet 700 carrying the preforms is transferred to the flipping station, where zirconia fiber preforms 900 are stacked on top of the pallet 700. Then, the pallet 700 containing the zirconia fiber preforms 900 is placed on the flipping frame 300, and the forming plate 800 is placed on top of the zirconia fiber preforms 900. The fixed clamp 500 is used to clamp and secure one edge, and the movable clamp is used to clamp and secure the other edge. Finally, the flipping frame 300 is operated to invert the preforms and pallet 700. During this process, a trolley is pushed under the flipping frame 300 to receive the flipped forming plate 800 and zirconia fiber preforms 900. After flipping, the upper pallet 700 is removed, the upper forming plate 800 is placed on top, and then the preforms are sent into the press for pressure.

[0028] Before flipping, the adjusting end of the fixed clamp 500 faces downwards, meaning the clamping bolt is above the zirconia fiber blank 900, facilitating the pushing of the zirconia fiber blank 900 in and making it easy to fix. The adjusting end of the movable clamp 600 faces upwards, meaning the clamping bolt is below the zirconia fiber blank 900. This arrangement ensures that after flipping, the clamping bolt is above the zirconia fiber blank 900, facilitating disassembly and preventing interference with the placement of the zirconia fiber blank 900 after flipping.

[0029] To facilitate position adjustment of the fixed clip 500, the fixed clip 500 is detachably mounted and fixed to the flip frame 300 via a movable base 110 and threaded fasteners. Combined with the movable clip 600, it can accommodate products of different specifications.

[0030] To ensure the stability of the tilting frame 300 before tilting, the limiting block 320 is movably fixed to the top of the support column by a limiting fastener 321 to achieve locking. The limiting fastener 321 can be a bolt or a pin. Correspondingly, the support column has a threaded hole or a pin hole, and the limiting block 320 has a fixing hole. The locking needs to be released before tilting.

[0031] To facilitate the movement and leveling of the device, the chassis 100 is equipped with wheels 120 and a base 110 for support and leveling. This ensures both the flexibility of movement and the ability to provide stable support and leveling adjustments as needed, adapting to different production site requirements.

[0032] To facilitate the placement of the movable clip 600, the top of the column 200 is provided with a hanging groove for placing the fixed clip 500, which can be a square tube as in this embodiment.
