Description

Technical Field

[0001] This utility model relates to the field of isostatic pressing special graphite material preparation technology, and in particular to an isostatic pressing graphite loading device. Background Technology

[0002] Isostatic graphite, with its excellent physicochemical properties, is widely used in high-end fields such as nuclear industry, semiconductors, and photovoltaics. In its production process, the loading stage is a key step in ensuring product quality, directly affecting the uniformity of green compact density and the performance of subsequent products.

[0003] However, the current isostatic graphite loading process faces many technical challenges:

[0004] First, graphite powder itself has poor fluidity, and uneven loading is very likely to occur during the loading process, resulting in significant density differences in different parts of the green body, which affects the overall performance consistency of the product.

[0005] Secondly, the density of graphite powder varies due to factors such as storage conditions, ambient humidity, and particle size distribution, making it difficult to accurately control the weight of each charge. This increases the difficulty of adjusting subsequent process parameters such as sintering and can easily lead to an increased scrap rate.

[0006] Furthermore, the loading process relies on manual operation, and the experience and skill level of the operators vary. Improper operation can cause fluctuations in the loading weight, making it difficult to achieve standardized and large-scale production.

[0007] In addition, existing feeding devices often use the method of directly discharging material from the top of the rubber sleeve. During the process of the powder falling, a large amount of dust is generated, which not only wastes the powder and pollutes the production environment, but also poses a threat to the health of the operators. Utility Model Content

[0008] The purpose of this invention is to provide an isostatic graphite loading device, which solves the above-mentioned problems.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an isostatic graphite loading device, comprising a weighing base, a mold and a feeding pipe, wherein the mold is installed on the top of the weighing base, a rubber sleeve is provided inside the mold, a top frame is provided above the mold, supports are fixed on both sides of the top frame, a feeding pipe is provided inside the top frame, and a moving component is provided at one end of the feeding pipe.

[0010] Preferably, the feed tube extends into the interior of the rubber sleeve and can move within the rubber sleeve in conjunction with the moving component.

[0011] Preferably, the moving component includes a support base disposed at one end of the feed tube, a telescopic rod installed on the top of the support base, a connecting block fixedly attached to the bottom of the telescopic rod protruding from the bottom of the support base, the connecting block being fixedly connected to the feed tube, and a laser rangefinder installed on one side of the support base.

[0012] Preferably, longitudinal slide rails are provided on both sides of the bottom of the support base, and longitudinal sliders are slidably provided on the top of the longitudinal slide rails, with the longitudinal sliders fixed to both sides of the bottom of the support base.

[0013] Preferably, transverse guide rails are installed at both ends of the top of the top frame, and transverse sliders are installed at both ends of the bottom of the longitudinal slide rail, with the transverse sliders slidably mounted on the transverse guide rails.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model provides an isostatic graphite loading device that uses a weighing sensor and a laser rangefinder to provide real-time feedback on the loading status. Combined with the three-dimensional movement function of the feeding tube (vertical lifting, forward and backward movement, and left and right translation), it achieves precise feeding to different positions within the mold sleeve. The feeding tube can dynamically adjust the spacing between itself and the material according to the material surface height. Coupled with the layered and stacked loading trajectory planning, it ensures uniform distribution of graphite raw materials, improves the density uniformity of the product from the source, reduces internal defects caused by uneven loading, and provides quality assurance for high-precision, high-reliability products.

[0016] 2. This utility model provides an isostatic graphite loading device that, through fully automated control, uses a PLC system to link components such as telescopic rods and slider guides to achieve automatic positioning, feeding, and trajectory movement of the feeding tube, significantly reducing manual intervention. During the loading process, the feeding tube can automatically complete multiple stages of operation according to a preset program, including "rapid filling - uniform spreading - precise finishing," avoiding errors and delays caused by manual operation, significantly improving loading efficiency, simplifying the production process, and adapting to the needs of large-scale production.

[0017] 3. This utility model provides an isostatic graphite loading device that, through precise control of loading uniformity and quantity, effectively reduces the incidence of defects such as cracks and deformation during the product molding process, reduces subsequent processing and repair steps, and lowers material waste and process complexity. The automated operation mode also reduces labor costs, avoids equipment failures or production interruptions caused by human error, and improves process stability and production economy.

[0018] 4. This utility model provides an isostatic graphite loading device with a controllable discharge pipe height design, which reduces impact dust during material feeding. Combined with a closed material transport channel, it reduces dust pollution in the production environment and improves workshop operating conditions. The device optimizes energy consumption during operation, reducing energy waste, conforming to the concept of green manufacturing, and helping enterprises achieve sustainable production.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0027] Combination Figures 1 to 5 As shown, an isostatic graphite loading device of the present invention includes a weighing base 1, a mold 2 and a feeding pipe 4. The mold 2 is installed on the top of the weighing base 1. A rubber sleeve 21 is provided inside the mold 2. A top frame 3 is provided above the mold 2. Supports 31 are fixed on both sides of the top frame 3. The feeding pipe 4 is provided inside the top frame 3. A movable component is provided at one end of the feeding pipe 4.

[0028] The feeding tube 4 extends into the interior of the rubber sleeve 21 and can move within the rubber sleeve 21 in conjunction with the moving component.

[0029] The moving component includes a support base 6 disposed at one end of the feed tube 4. A telescopic rod 61 is installed on the top of the support base 6. The output end of the telescopic rod 61 protrudes from the bottom of the support base 6 and a connecting block 62 is fixed thereon. The connecting block 62 is fixedly connected to the feed tube 4. A laser rangefinder 63 is installed on one side of the support base 6.

[0030] The support base 6 has longitudinal slide rails 7 on both sides of its bottom, and longitudinal sliders 71 are slidably mounted on the top of the longitudinal slide rails 7. The longitudinal sliders 71 are fixed to both sides of the bottom of the support base 6.

[0031] The top of the top frame 3 is equipped with transverse guide rails 5 at both ends, and the bottom of the longitudinal slide rail 7 is equipped with transverse sliders 51 at both ends. The transverse sliders 51 are slidably mounted on the transverse guide rails 5.

[0032] Specifically, an injection pipe is connected to the feed pipe 4. Isostatic graphite raw material is injected into the feed pipe 4 through the injection pipe, and then the feed pipe 4 injects the isostatic graphite raw material into the rubber sleeve 21 inside the mold 2, thus completing the loading operation of the isostatic graphite raw material.

[0033] The telescopic rod 61 is used to move the feeding pipe 4 up and down, so that the feeding pipe 4 extends into the rubber sleeve 21 at different heights, ensuring the distance between the bottom of the feeding pipe 4 and the material surface, preventing the material from burying the bottom of the feeding pipe 4 and affecting the loading of the material.

[0034] The longitudinal slider 71 moves on top of the longitudinal slide rail 7. The longitudinal slider 71 drives the support base 6 and the telescopic rod 61 to move, which in turn drives the feed tube 4 to move, so that the feed tube 4 can move back and forth within the rubber sleeve 21.

[0035] The horizontal slider 51 moves on the top of the horizontal guide rail 5. The horizontal slider 51 drives the vertical guide rail 7 to move, which in turn drives the feed tube 4 to move, so that the feed tube 4 can move left and right within the rubber sleeve 21.

[0036] A high-precision weighing sensor with an accuracy of ±0.1% is integrated inside the weighing base 1. The laser rangefinder 63 is located above the mold 2. The weighing sensor and the laser rangefinder 63 provide real-time feedback to adjust the loading amount and loading speed.

[0037] Furthermore, the feeding tube 4 is first inserted into the bottom of the rubber sleeve 21, and the material is released from the center line about 30cm from the bottom. The loading height and weight are measured in real time and automatically calculated. By controlling the frequency of the unloader, the loading speed is automatically controlled, and the movement of the feeding tube 4 in all directions inside the rubber sleeve 21 is controlled to achieve uniform loading. When the loading weight reaches 95%, the feeding speed is reduced by 60%, and the distance from the material surface is controlled at 5cm until the required loading weight is reached.

[0038] The moving loading trajectory of the feed pipe 4 is as follows: Figure 5As shown, the raw materials are stacked in layers in this manner.

[0039] This design makes the feeding process more precise and controllable, reduces manual intervention, and improves production efficiency; the controllable height feeding pipe 4 design can reduce dust generation, thus saving energy and protecting the environment.
