Description

Technical Field

[0001] This utility model relates to the field of graphite isostatic pressing technology, specifically to an isostatic pressing equipment for processing low resistivity graphite. Background Technology

[0002] Low resistivity graphite is a type of graphite material with excellent electrical conductivity. Due to its high purity, good crystal structure, and uniform microstructure, its resistivity is significantly lower than that of ordinary graphite. In the processing of low resistivity graphite, cold isostatic pressing is usually used to shape graphite powder, so that the graphite particles are subjected to uniform pressure in all directions, thereby obtaining a graphite blank with uniform density and dense structure. This uniform structure is conducive to electron conduction and reduces resistivity.

[0003] The aforementioned and existing related technologies often have the following drawbacks: During processing, graphite powder is generally poured into a mold, and then the mold is moved into a hydraulic frame for extrusion molding via a pulley assembly and drive frame. However, after each graphite processing and molding, the graphite in the mold needs to be removed before graphite can be poured back into the mold. This makes it impossible to perform other operations during the graphite cold isostatic pressing process, which greatly reduces the processing efficiency of cold isostatic pressing equipment for low resistivity graphite.

[0004] Therefore, we propose an isostatic pressing equipment for processing low resistivity graphite. Utility Model Content

A cylinder is mounted on one side of the hydraulic frame, and a main unit is fixedly connected to one side of the base frame.

[0012] Preferably, a guide block is fixedly connected to the lower end of the card rod, and the arc surface of the guide block is slidably connected to the inner wall of the card frame.

[0013] The effect achieved by the above components is that the guide block is inserted into the card frame with the help of the card rod, and the guide block plays the role of quickly guiding the card rod.

[0030] Please see Figure 1 This utility model provides a technical solution: an isostatic pressing device for processing low resistivity graphite, comprising a base frame 1, two pulley assemblies 10, a turntable 201, and four positioning plates 208. A hydraulic frame 5 is fixedly connected to the upper surface of the base frame 1, and a drive frame 11 is fixedly connected to the upper surface of the two pulley assemblies 10. A cylinder 6 is installed on one side of the hydraulic frame 5, a main unit 7 is fixedly connected to one side of the base frame 1, and a housing 8 is fixedly connected to the side of the base frame 1 away from the main unit 7. Two replenishment tanks 9 are fixedly connected to the upper surface of the base frame 1 relative to the side of the hydraulic frame 5. The inner wall of the base frame 1... The device is equipped with a material changing structure 2, which allows for the reloading of the mold 4 during the cold isostatic pressing process of low resistivity graphite. This minimizes the problem of reduced efficiency in the cold isostatic pressing process of low resistivity graphite due to the inability of personnel to perform other operations during the graphite processing in the mold 4. The upper surface of the turntable 201 is equipped with a limiting structure 3, which limits the positioning plate 208. With the cooperation of various components, the retracted positioning plate 208 can be temporarily limited, and both positioning plates 208 can be easily retracted at the same time after opening, thereby reducing the complexity of operation and improving the practicality of the device.

[0031] The following section will explain the specific design and function of its material changing structure 2 and limiting structure 3.

[0032] like Figures 2-5As shown, the lower surface of the turntable 201 is rotatably connected to the bottom frame 1. Two secondary rails 202 are fixedly connected to the upper surface of the turntable 201. The arc surface of the pulley assembly 10 is slidably connected to the inner wall of the secondary rails 202. Two L-shaped frames 203 are fixedly connected to the upper surface of the turntable 201. A locking rod 204 is slidably connected to the inner wall of the L-shaped frame 203. Two locking frames 207 are fixedly connected to the upper surface of the bottom frame 1. The inner wall of the locking frame 207 is slidably connected to the locking rod 204. Two main rails 206 are fixedly connected to the upper surface of the bottom frame 1. The arc surface of the pulley assembly 10 is slidably connected to the inner wall of the main rails 206. Two fixed frames 205 are fixedly connected to the upper surface of the turntable 201. Four positioning plates 208 are grouped in pairs. The side of each group of positioning plates 208 that is close to each other is rotatably connected to the fixed frame 205. One side of the positioning plate 208 abuts against the drive frame 11.

[0033] Both sides of the fixed frame 205 are fixedly connected to L-shaped plates 209. The lower surface of the positioning plate 208 abuts against the long arm of the L-shaped plate 209. The positioning plate 208 rotates to fit against the long arm of the L-shaped plate 209. The L-shaped plate 209 serves to support the positioning plate 208. The upper surfaces of the two fixed frames 205 are fixedly connected to a top plate 210. The upper surface of the top plate 210 is slidably connected to the inner wall of the drive frame 11. The drive frame 11 moves from the upper surface of the top plate 210. The top plate 210 achieves the effect of increasing the support area of ​​the fixed frame 205 and improving the stability of the pulley assembly 10 during movement. The lower end of the clamping rod 204 is fixedly connected to a guide block 211. The arc surface of the guide block 211 is slidably connected to the inner wall of the clamping frame 207. The guide block 211 is inserted into the clamping frame 207 with the help of the clamping rod 204. The guide block 211 serves to quickly guide the clamping rod 204.

[0034] like Figure 4 As shown, the limiting structure 3 includes a vertical rod 31, the lower end of which is fixedly connected to the turntable 201, and a horizontal rod 32 fixedly connected to the upper end of the vertical rod 31. Four positioning plates 208 are grouped in pairs, and a connecting rope 33 is fixedly connected to the side of each group of positioning plates 208 that is close to each other, which achieves the effect of limiting the positioning plates 208. With the cooperation of various components, the retracted positioning plates 208 can be temporarily limited, and it is convenient to retract the two positioning plates 208 at the same time after opening, thereby reducing the complexity of operation and improving the practicality of the device. The arc surface of the horizontal rod 32 has two inner grooves 34. The arc surface of the connecting rope 33 is slidably connected to the inner wall of the inner groove 34. The connecting rope 33 moves into the inner groove 34, and the inner groove 34 plays a better role in locking the connecting rope 33 to prevent it from falling off. The connecting rope 33 is a nylon rope, and the horizontal rod 32 is an acrylic rod. With the help of the acrylic rod, the horizontal rod 32 makes it convenient for personnel to observe the position of the inner groove 34.

[0035] Working principle: When cold isostatic pressing is required for low resistivity graphite, graphite is first poured into mold 4. Then, the clamping rod 204 is moved away from the clamping frame 207 via the L-shaped frame 203. After the clamping rod 204 drives the guide block 211 to disengage from the clamping frame 207, the guide block 211 quickly guides the clamping rod 204. The drive frame 11 rotates, driving the two molds 4 to rotate. The pulley assembly 10 rotates via the turntable 201 through the auxiliary rail 202. After rotating to 180 degrees, the graphite is poured into one side of mold 4 near the hydraulic frame 5. Then, the positioning plate 208 is retracted and disengaged from the L-shaped plate 209 through the limiting structure 3. The L-shaped plate 209 supports the positioning plate 208, allowing the positioning plate 208 to disengage from the drive frame 11. The drive frame 11 is then moved closer to the hydraulic frame 5. The drive frame 11 moves from the top plate 207. The upper surface of the pulley assembly 10 slides, and the top plate 210 achieves the effect of increasing the support area of ​​the fixed frame 205 and improving the stability of the pulley assembly 10 during movement. The pulley assembly 10 moves from the secondary rail 202 to the main rail 206 through the drive frame 11. After the drive frame 11 is completely moved into the hydraulic frame 5, the hydraulic frame 5 is started by the host 7, and the internal components of the machine box 8 work again, so that the replenishing tank 9 replenishes the hydraulic frame 5 with liquid. At the same time, the cylinder 6 works to fix the mold 4, so that the hydraulic cylinder in the hydraulic frame 5 squeezes the graphite in the mold 4 to form. During this process, the personnel can continue to pour the graphite into another mold 4, so that after the front mold 4 is cold isostatically pressed, the pulley assembly 10 rotates backward through the limit of the positioning plate 208, so that the two molds 4 are used alternately, thereby greatly improving the efficiency of cold isostatic pressing of low resistivity graphite.

[0036] When the drive frame needs to be moved, first pull the connecting rope 33 into the inner groove 34 of the crossbar 32. The crossbar 32 of the acrylic rod makes it easier for personnel to observe the position of the inner groove 34. At this time, the two ends of the connecting rope 33 are retracted, which drives the positioning plate 208 to rotate. The nylon connecting rope 33 can improve its own service life and disengage from the drive frame 11 and the long arm of the L-shaped plate 209. At this time, the drive frame 11 can be moved. Due to the disengagement of the positioning plate 208 from the drive frame 11, the drive frame 11 can be moved into the hydraulic frame 5 with the help of the pulley assembly 10, so that the two positioning plates 208 can be quickly moved and reset, which is convenient for personnel to operate quickly.

[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
