Description

Technical fields:

[0001] This utility model belongs to the field of horizontal isostatic press manufacturing, and particularly relates to a maintenance device for horizontal isostatic presses. Background technology:

[0002] An isostatic press is a molding device that operates under ultra-high pressure. Isostatic pressing involves placing the object to be processed in a specific mold, then placing the mold containing the workpiece into a sealed container filled with oil. The pressure is gradually increased through a pressurization system, and through the pressure transmission of the liquid, all surfaces of the object are subjected to equal pressure, forming the object under the constraint of the mold.

[0003] Isostatic presses are mainly divided into vertical and horizontal types. They consist primarily of a prestressed frame, a pressure vessel capable of withstanding ultra-high pressure, a pressurization system, hydraulic transmission, and electrical control components. During the manufacturing, testing, and subsequent use of horizontal isostatic presses, after the workpiece is formed, the sealing caps (also called plugs) at both ends of the pressure vessel are removed. The oil injected into the pressure vessel's inner cavity then naturally drains out from the openings at both ends. Because oil has a certain viscosity, and the pressure vessel is horizontally positioned in the isostatic press, some oil remains adhered to the inner cavity of the pressure vessel after drainage and cannot be removed in time. When the horizontal isostatic press stops processing workpieces for an extended period, external impurities enter the inner cavity of the pressure vessel and adhere to this residual oil, eventually forming difficult-to-clean oil sludge that cannot be removed. This leads to damage to subsequent workpieces produced by the isostatic press, thus affecting the normal operation of the isostatic press. Summary of the Invention:

[0004] The purpose of this utility model is to provide a horizontal isostatic press maintenance device, which overcomes the shortcomings of the prior art and effectively solves the existing problem of cleaning residual oil in the inner cavity of pressure vessels.

[0005] The present invention relates to a maintenance device for a horizontal isostatic press, comprising a sleeve, a through hole coaxially formed on the cross-section of the sleeve, a round rod slidably connected within the through hole, a scraper coaxially mounted on the inner end of the round rod, a push handle mounted on the outer end of the round rod, the outer circumferential surface of the scraper slidingly fitting against the inner circumferential surface of the pressure vessel, a spring fitted on the round rod between the sleeve and the push handle, and an auxiliary reinforcement assembly provided on the sleeve.

[0006] Furthermore, a pressure plate is coaxially fixedly mounted on the round rod, and the pressure plate is located between the push handle and the spring.

[0007] Furthermore, the auxiliary reinforcement component includes a bracket frame, and a plurality of bracket frames are evenly installed on the outer circumferential surface of the sleeve. A screw hole is provided on the cross plate of the bracket frame, and a set screw is screwed into the screw hole. An insertion hole matching the set screw is provided on the circumferential surface of the sleeve.

[0008] Furthermore, the inner diameter of the sleeve is the same as the outer diameter of the cylindrical outer edge of the pressure vessel.

[0009] Furthermore, a chamfer is provided on the outer circular edge of the inner cavity of the sleeve.

[0010] Furthermore, the scraper is made of rubber.

[0011] Furthermore, the inner end of the round rod is fixedly connected to the scraper by bolts.

[0012] The beneficial effects of this utility model are: This device has a simple structure and is easy to operate. By inserting the round rod into the inner cavity of the pressure vessel and pushing the scraper, the residual oil in the inner cavity of the pressure vessel can be scraped clean, thereby realizing the rapid cleaning and maintenance of the pressure vessel and ensuring the normal production of subsequent workpieces of the isostatic press.

[0014] Figure 2 This is a partial cross-sectional view of the utility model in use.

[0015] In the diagram, 1 is a sleeve, 2 is a round rod, 3 is a scraper, 4 is a push handle, 5 is a pressure vessel, 6 is an inner cavity, 7 is a spring, 8 is a pressure plate, 9 is a support frame, 10 is a set screw, and 11 is a cylindrical outer edge. Detailed implementation method:

[0016] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0017] like Figures 1 to 2As shown, a horizontal isostatic press care device includes a sleeve 1 with a through hole coaxially formed on its cross-section. A round rod 2 is slidably connected within the through hole. A scraper 3 is coaxially mounted on the inner end of the round rod 2, and a push handle 4 is mounted on the outer end of the round rod 2. The outer circumferential surface of the scraper 3 is slidably fitted with the circumferential surface of the inner cavity 6 of the pressure vessel 5. A spring 7 is fitted on the round rod 2, located between the sleeve 1 and the push handle 4. An auxiliary reinforcement assembly is provided on the sleeve 1. A pressure plate 8 is coaxially fixedly mounted on the round rod 2, located between the push handle 4 and the spring 7. The inner diameter of the sleeve 1 is the same as the outer diameter of the cylindrical outer edge 11 of the pressure vessel 5. A chamfer is formed on the circular outer edge of the inner cavity of the sleeve 1.

[0018] Specifically, by inserting the round rod 2 into the inner cavity 6 of the pressure vessel 5 and pushing the scraper 3, the residual oil in the inner cavity 6 of the pressure vessel 5 can be scraped clean.

[0019] In actual use, after the oil in the inner cavity 6 of the horizontal isostatic press pressure vessel 5 is drained, the sleeve 1 is aligned with the cylindrical outer edge 11 of the pressure vessel 5 and engaged with it, allowing the scraper 3 to accurately enter the inner cavity 6. At this time, the operator holds the push handle 4 to push the round rod 2 to move, and the spring 7 is gradually compressed. The round rod 2 drives the scraper 3 to move in the inner cavity 6 of the pressure vessel 5. During this process, the outer circumferential surface of the scraper 3 slides and fits against the circumferential surface of the inner cavity 6, allowing the scraper 3 to scrape up the residual oil in the inner cavity 6. As the scraper 3 continues to move, the scraped residual oil is eventually... The pressure vessel 5 is pushed to the other end of the cylindrical outer edge 11 to discharge the pressure. When the spring 7 rebounds, it drives the round rod 2 and scraper 3 to quickly reset, further reducing the labor intensity of the workers. During this process, when the spring 7 rebounds against the pressure plate 8, it can not only quickly reset the round rod 2 and scraper 3, but also prevent the outer end of the spring 7 from squeezing the workers' hands. The inner diameter of the sleeve 1 is the same as the outer diameter of the cylindrical outer edge 11 of the pressure vessel 5, making the two more stable after they are fastened together. The inner circular outer edge of the sleeve 1 is chamfered, making it easier to be fastened to the cylindrical outer edge 11.

[0020] like Figures 1 to 2 As shown, a horizontal isostatic press maintenance device includes an auxiliary reinforcement component comprising a support frame 9. Several support frames 9 are evenly installed on the outer circumferential surface of the sleeve 1. A screw hole is provided on the horizontal plate of the support frame 9, and a set screw 10 is screwed into the screw hole. An insertion hole matching the set screw 10 is provided on the circumferential surface of the sleeve 1. The scraper 3 is made of rubber, and the inner end of the round rod 2 is fixedly connected to the scraper 3 by bolts.

[0021] Specifically, the auxiliary reinforcement components can further secure the care device to the pressure vessel 5, thereby facilitating the observation of the residual oil cleaning status of the pressure vessel 5 after the staff leaves.

[0022] In actual use, after the sleeve 1 is engaged with the cylindrical outer edge 11 of the pressure vessel 5, the set screw 10 is rotated to screw it into the corresponding insertion hole of the sleeve 1. As several set screws 10 contact and tighten with the cylindrical outer edge 11, the nursing device can be further fixed on the pressure vessel 5. This allows the operator to move to the other end of the pressure vessel 5 and observe the condition of the residual oil in the inner cavity 6. If it is not completely cleaned, the round rod 2 can be repeatedly pushed so that the scraper 3 can scrape off the residual oil in the inner cavity 6 multiple times. The bracket frame 9 makes it easy for the operator to observe the rotation position of the set screw 10, thereby preventing the set screw 10 from coming off when it is unscrewed. The rubber scraper 3 prevents it from scratching or damaging the inner cavity 6 of the pressure vessel 5. The inner end of the round rod 2 is fixedly connected to the scraper 3 with bolts, which facilitates the quick disassembly and replacement of the scraper 3 after it is worn.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
