Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing ring processing technology, and in particular to a carbon graphite sealing ring processing device. Background Technology
[0002] Carbon graphite sealing rings are widely used in high-end equipment fields such as petrochemicals, nuclear power, aerospace, and marine propulsion due to their high temperature resistance, corrosion resistance, low coefficient of friction, and self-lubricating properties.
[0003] In existing technologies, after the processing is completed, the sealing ring and the inner wall of the mold will form an extremely tight fit. This tight fit requires a lot of time and effort to separate during the subsequent demolding operation. The cumbersome demolding process not only significantly reduces the overall processing efficiency and prolongs the production cycle, but also poses a significant risk that the edges of the product may be damaged during demolding, thereby affecting the quality and appearance of the product. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a carbon graphite sealing ring processing device, comprising an operating table, a support frame and a mold.
[0006] A support frame is fixedly connected to the top of the operating table, a hydraulic cylinder is fixedly connected to the top of the support frame, a hydraulic rod is fixedly connected to the output end of the hydraulic cylinder, a pressing block is fixedly connected to the telescopic end of the hydraulic rod, a connecting plate is fixedly connected to the top of the operating table, a connecting groove is provided on the top of the connecting plate, a bidirectional lead screw is provided inside the connecting groove, a driving mechanism is fixedly installed on the outer surface of the connecting plate, the output end of the driving mechanism is fixedly connected to one end of the bidirectional lead screw, the mold is threadedly connected to the bidirectional lead screw, a groove is provided in the center of the top of the operating table, a connecting frame is fixedly connected to the bottom of the operating table, a connecting column is fixedly installed on the inner bottom wall of the connecting frame, and an air bladder is provided on the outer surface of the connecting column.
[0007] Furthermore, the mold includes a first module and a second module, both of which are threadedly connected to the outer surface of the bidirectional lead screw, and the inner walls of both the first module and the second module are provided with buffer components.
[0008] Furthermore, the buffer assembly includes a buffer spring fixedly connected to the inner walls of the first module and the second module, and a buffer plate is fixedly connected to the end of the buffer spring away from the inner wall of the first module.
[0009] Furthermore, the first module and the second module are symmetrically distributed on the outer surface of the bidirectional lead screw.
[0010] Furthermore, the pressing block is fixedly connected to the telescopic end of the hydraulic rod via a lifting plate, the lifting plate is slidably connected to the support frame, and the lifting plate and the pressing block are connected by a flange.
[0011] Furthermore, an electric actuator is fixedly connected to the inner bottom wall of the connecting frame, and a fixing plate is fixedly connected to the telescopic end of the electric actuator. The fixing plate is slidably connected to the inner wall of the connecting frame, and the connecting column is fixedly connected to the top of the fixing plate.
[0012] Furthermore, an air pump is fixedly connected to the air inlet of the airbag via an air inlet tube, and the air pump is fixedly connected to the inner bottom wall of the connecting frame.
[0013] Furthermore, a support pad is fixedly connected to the bottom of the connecting frame.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] In this invention, a drive mechanism rotates a bidirectional lead screw, allowing the first and second modules to close and separate, thus achieving initial demolding. Simultaneously, the buffer assembly on the inner wall of the mold absorbs the instantaneous impact force during the pressing process through the elastic deformation of the buffer spring, preventing the carbon graphite material from shattering due to excessive force and effectively improving the product qualification rate. Furthermore, an electric push rod pushes the fixed plate upward, which in turn drives the connecting column and airbag through the groove and into the mold. The airbag is then inflated by an air pump, causing it to push the sealing ring away from the inner wall of the mold, achieving automatic demolding. This not only simplifies the operation process and improves processing efficiency but also reduces product damage caused by manual contact. Attached Figure Description

[0024] Please see Figure 1-6 This utility model provides a technical solution: a carbon graphite sealing ring processing device, including an operating table 1, a support frame 2 and a mold 3.
[0025] The specific setup and function of the control panel 1 and airbag 7 will be explained below.
[0026] In this implementation scheme: a support frame 2 is fixedly connected to the top of the operating table 1, a hydraulic cylinder 4 is fixedly connected to the top of the support frame 2, a hydraulic rod 41 is fixedly connected to the output end of the hydraulic cylinder 4, a pressing block 5 is fixedly connected to the telescopic end of the hydraulic rod 41, a connecting plate 11 is fixedly connected to the top of the operating table 1, a connecting groove 12 is provided on the top of the connecting plate 11, a bidirectional lead screw 13 is provided inside the connecting groove 12, a drive mechanism 14 is fixedly installed on the outer surface of the connecting plate 11, the output end of the drive mechanism 14 is fixedly connected to one end of the bidirectional lead screw 13, the mold 3 is threadedly connected to the bidirectional lead screw 13, a groove 15 is provided in the center of the top of the operating table 1, a connecting frame 16 is fixedly connected to the bottom of the operating table 1, a connecting column 6 is fixedly installed on the inner bottom wall of the connecting frame 16, and an airbag 7 is provided on the outer surface of the connecting column 6.
[0027] The aforementioned components achieve the following effects: the operating table 1 serves as the supporting foundation of the overall structure, supporting the hydraulic cylinder 4 and hydraulic rod 41 via the support frame 2, providing vertical power for the pressing process. The cooperation between the connecting plate 11 and the bidirectional lead screw 13 allows the first module 31 and the second module 32 of the mold 3 to separate or close synchronously in the horizontal direction, achieving automatic demolding.
[0028] Specifically, the mold 3 includes a first module 31 and a second module 32. Both the first module 31 and the second module 32 are threadedly connected to the outer surface of the bidirectional lead screw 13. Both the inner walls of the first module 31 and the second module 32 are provided with buffer components 33.
[0029] The aforementioned components achieve the following effects: Mold 3 adopts a split design, with the first module 31 and the second module 32 moving synchronously in opposite directions or in the same direction via the rotation of the bidirectional lead screw 13. When the bidirectional lead screw 13 rotates, the two modules slide along the connecting groove 12, completing the pressing or demolding action of the sealing ring. The buffer assembly 33 can absorb instantaneous impact force during the pressing process, preventing the carbon graphite material from shattering due to stress concentration.
[0030] Specifically, the buffer assembly 33 includes a buffer spring 331 fixedly connected to the inner walls of the first module 31 and the second module 32, and a buffer plate 332 is fixedly connected to the end of the buffer spring 331 away from the inner wall of the first module 31.
[0031] The effect achieved by the above components is that the buffer spring 331 and the buffer plate 332 form an elastic support structure. When the hydraulic cylinder 4 drives the pressing block 5 to press down, the buffer plate 332 first contacts the carbon graphite material, and the pressure is dispersed by the compression deformation of the buffer spring 331, so that the material is evenly stressed and cracks are reduced.
[0032] Specifically, the first module 31 and the second module 32 are symmetrically distributed on the outer surface of the bidirectional lead screw 13.
[0033] The aforementioned components achieve the following effects: the symmetrical distribution design ensures that the two modules move synchronously when the bidirectional lead screw 13 rotates, maintaining the symmetry of the internal cavity of the mold 3 and avoiding deviations in the sealing ring size due to uneven force. This symmetrical structure also simplifies the control logic of the drive mechanism 14 and improves the stability of the device.
[0034] Specifically, the pressing block 5 is fixedly connected to the telescopic end of the hydraulic rod 41 via the lifting plate 51, the lifting plate 51 is slidably connected to the support frame 2, and the lifting plate 51 is flange-connected to the pressing block 5.
[0035] The aforementioned components achieve the following effects: the sliding connection between the lifting plate 51 and the support frame 2 provides vertical guidance for the pressing block 5, ensuring that the pressing block 5 remains horizontal during the pressing process and preventing uneven force on the mold 3 due to tilting. The flange connection facilitates the disassembly and replacement of the pressing block 5, and a suitable pressing block 5 can be selected according to the sealing ring of different sizes.
[0036] Specifically, an electric push rod 61 is fixedly connected to the inner bottom wall of the connecting frame 16, and a fixing plate 62 is fixedly connected to the telescopic end of the electric push rod 61. The fixing plate 62 is slidably connected to the inner wall of the connecting frame 16, and the connecting column 6 is fixedly connected to the top of the fixing plate 62.
[0037] The aforementioned components achieve the following effects: the electric actuator 61, by driving the fixed plate 62 to slide along the inner wall of the connecting frame 16, can precisely control the lifting height of the connecting column 6. When demolding is required, the electric actuator 61 pushes the connecting column 6 upward, allowing the airbag 7 to pass through the groove 15 and enter the mold 3, providing a positional basis for subsequent inflation and demolding. The sliding fixed plate 62 reduces frictional resistance, ensuring smooth movement.
[0038] Specifically, an air pump 71 is fixedly connected to the air inlet of the airbag 7 via an air inlet tube, and the air pump 71 is fixedly connected to the inner bottom wall of the connecting frame 16.
[0039] The aforementioned components achieve the following effect: the air pump 71 injects gas into the airbag 7 through the inflation pipe, causing it to expand inside the mold 3. The expanded airbag 7 can push the sealing ring from the inside, reducing the friction between the sealing ring and the inner wall of the mold 3, thus achieving demolding without damage. The degree of expansion of the airbag 7 can be precisely controlled by the inflation volume to adapt to the manufacturing requirements of sealing rings with different thicknesses and inner diameters.
[0040] Specifically, a support pad 17 is fixedly connected to the bottom of the connecting frame 16.
[0041] The aforementioned components achieve the following effects: the support pad 17, made of anti-slip and wear-resistant material, increases the contact area between the device and the ground, distributes the overall weight of the device, and improves stability during processing. When the electric actuator 61 pushes the connecting column 6 upward, the support pad 17 effectively prevents the operating table 1 from shifting or shaking due to the reaction force.
[0042] Working principle: The mixed and uniform carbon graphite powder is placed between the first module 31 and the second module 32 of the mold 3. The bidirectional lead screw 13 is finely adjusted by the drive mechanism 14 to match the cavity size of the mold 3 with the target sealing ring. The hydraulic cylinder 4 is activated, and the hydraulic rod 41 drives the pressing block 5 to move downward, applying pressure to the carbon graphite powder in the mold 3. The buffer spring 331 and the buffer plate 332 of the buffer assembly 33 absorb the instantaneous impact force, ensuring that the material is uniform and dense.
[0043] After pressing, the hydraulic cylinder 4 is reset, and the drive mechanism 14 drives the bidirectional lead screw 13 to rotate, so that the first module 31 and the second module 32 move to both sides synchronously, initially separating the mold 3. The electric push rod 61 pushes the connecting column 6 to rise, so that the air bag 7 extends into the mold 3. The air pump 71 inflates the air bag 7, and the inflated air bag 7 pushes the sealing ring from the inside, so that it is separated from the inner wall of the mold 3, completing the demolding without damage.
