Description

Technical Field

[0001] This utility model belongs to the technical field of six-sided top press, and in particular relates to a device for preventing oil leakage from the guide sleeve of a hinged six-sided top press and providing early warning. Background Technology

[0002] The core equipment for synthesizing superhard materials is a hinged six-sided press. Its working principle involves providing high pressure through a hydraulic system while simultaneously generating high temperature using low voltage and high current, creating the necessary pressure and temperature environment for superhard material synthesis. During assembly, six hinge beams are interconnected via pins passing through pin holes. The cylinder and cylinder bottom are fixed inside the hinge beams, and the piston reciprocates within the cylinder. The core function of the guide sleeve is to prevent piston rotation. However, during long-term operation in superhard material synthesis, the frequent reciprocating motion of the piston causes wear on the sealing ring between it and the guide sleeve, leading to frequent oil leakage at the connection between the guide sleeve and the piston.

[0003] Chinese patent application CN221401619U discloses a device for preventing oil leakage and relieving pressure in a six-sided top press, including a guide sleeve and a piston. The piston is installed inside the guide sleeve and slides in cooperation with it. A piston ring is provided between the piston and the guide sleeve. The advantages of this invention are: it not only ensures no leakage but also avoids the periodic expansion and contraction pressure and plastic deformation borne by a single O-ring seal rubber, thus improving production efficiency and reducing maintenance cycles.

[0004] The aforementioned device focuses on improving the sealing structure to prevent oil leakage and pressure relief, but does not consider the timely monitoring and early warning of oil seepage in actual production. In the process of synthesizing superhard materials, even if the piston ring can reduce the probability of oil seepage, wear between the piston ring and the guide sleeve and piston is inevitable as the equipment operates for a long time. Compared with the guide sleeves of the lower, front, rear, left and right cylinders, the oil seepage problem of the upper cylinder guide sleeve is unique. Slightly leaking hydraulic oil will drip under the action of gravity and is difficult to detect in time. Once oil seepage occurs, if it is not detected in time, it will still cause hydraulic oil to penetrate into the large and small pads, causing the pads to crack, disrupting the equipment's alignment, increasing the risk of damage to the cemented carbide top hammer, and may also drip onto the pyrophyllite blocks, contaminating the synthesis chamber and reducing the quality of superhard material synthesis. The insulating plate and insulating ring are easily oxidized and brittle under high temperature and high pressure environment when immersed in oil seepage for a long time, leading to a decrease or even loss of the equipment's insulation performance, which not only further reduces the synthesis quality, but also significantly increases the energy consumption in the synthesis process.

[0005] To address this issue, we provide a hinged six-sided top press device that prevents oil leakage from the guide sleeve and provides early warning, thereby resolving the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a device for preventing oil leakage from the guide sleeve of a hinged six-sided top press and providing early warning. Through the cooperation of the piston and the oil leakage warning component, the problem of oil leakage at the connection between the upper cylinder guide sleeve and the piston in the prior art is difficult to detect and easily leads to safety accidents.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a device for preventing oil leakage from the guide sleeve of a hinged six-sided top press and providing early warning. It includes a body, with a guide sleeve fixedly connected to the bottom of the body. A piston is mounted on the bottom of the guide sleeve, and an oil leakage warning component is mounted on the surface of the piston. The oil leakage warning component includes a sealing sleeve fitted at the connection between the guide sleeve and the piston. An oil guide pipe is mounted on one side of the bottom of the sealing sleeve, and one side of the oil guide pipe is connected to an oil tank. A proximity switch is mounted on one side of the top of the oil tank. Under the constraint of the guide sleeve, the piston reciprocates along a preset trajectory inside the cylinder of the six-sided top press. The oil guide pipe's routing conforms to the equipment's structural layout. A float is installed inside the oil tank, floating freely with the rise and fall of the oil level. When the amount of leaked oil collected in the tank gradually increases and the oil level rises to a preset warning position, the float rises synchronously with the oil level and approaches the piston. The proximity switch, upon detecting the float, immediately issues a warning signal to alert personnel that the guide sleeve is leaking oil and the leakage amount has reached the threshold requiring intervention. Through the sealing effect of the sealing sleeve at the connection between the guide sleeve and the piston, and the drainage and recovery of leaking oil via the oil guide pipe, hydraulic oil is effectively prevented from seeping into the large and small pads, preventing them from cracking due to prolonged contact with hydraulic oil. This ensures equipment alignment, reduces the risk of damage to the carbide top hammer, and prevents hydraulic oil from dripping onto the pyrophyllite blocks, preventing impurities from entering the synthesis chamber and ensuring the quality of superhard material synthesis. The warning mechanism formed by the proximity switch can promptly issue a signal when the leakage amount reaches the warning line, significantly increasing the probability of detecting oil leakage in the upper cylinder guide sleeve. The centralized recovery of leaking oil in the oil tank allows the recovered hydraulic oil to be processed and reused, reducing hydraulic oil waste and lowering production costs.

[0009] The present invention is further configured such that a hinge beam is fixedly connected to the surface of the machine body, and a pin hole is provided on one side of the hinge beam. By passing a pin through the pin hole, the six hinge beams can be hinged to each other, thereby integrating the six working cylinders into a cooperating whole.

[0010] The present invention is further configured such that a positioning sleeve is fixedly connected to the bottom of the guide sleeve, and an internal hexagon bolt is threaded to the bottom of the positioning sleeve. The positioning sleeve can cooperate with the internal hexagon bolt to position the guide sleeve, ensuring that the guide sleeve always maintains a preset coaxiality with the piston during installation and equipment operation.

[0011] The present invention is further configured such that a top hammer is provided on one side of the piston, and one side of the top hammer is fixedly connected to the piston by fasteners. The fixed connection between the top hammer and the piston by fasteners can ensure that the connection between the top hammer and the piston is firm and that there will be no relative displacement or loosening under high pressure working conditions.

[0012] The present invention is further configured such that the sealing sleeve has a U-shaped structure and is made of silicone. The U-shaped structure design of the sealing sleeve can form a more closely fitting enveloping seal with the connection between the guide sleeve and the piston, maximizing the collection of hydraulic oil leaking from the connection and improving the integrity of oil leakage collection. Utilizing the good elasticity and sealing properties of silicone, the sealing effect is enhanced, reducing the amount of leakage in the initial stage of oil leakage. At the same time, it has good high temperature resistance and can adapt to the high-temperature working environment in the process of synthesizing superhard materials.

[0013] The present invention is further configured such that a connector is connected to one side of the bottom of the sealing sleeve, and the bottom of the connector is connected to the oil guide pipe. The connector can provide a transition interface for the connection between the sealing sleeve and the oil guide pipe, thereby avoiding the pipe bending problem that occurs when the oil guide pipe is directly connected to the sealing sleeve.

[0014] The present invention is further configured such that the number of hinge beams is four sets, and they are symmetrically arranged. The four sets of symmetrically arranged hinge beams can make the overall structure of the six-sided top press more balanced and symmetrical, and evenly distribute the stress generated under high pressure to the four sets of hinge beams, so as to avoid fatigue damage to local hinge beams due to excessive stress and extend the service life of the hinge beams.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model effectively prevents the large and small pads from being soaked and cracked under high temperature and high pressure due to oil leakage from the upper cylinder guide sleeve through the anti-oil leakage warning component, thereby reducing equipment accidents caused by pad cracking. At the same time, it prevents the insulating plate and insulating ring from becoming brittle due to immersion in hydraulic oil, ensuring the insulation performance of the equipment, reducing energy consumption in the synthesis process, and preventing oil dripping onto the pyrophyllite blocks, which would cause impurities to be mixed into the synthesis cavity, thus ensuring the synthesis quality of superhard materials.

[0017] 2. This utility model centrally recovers leaked hydraulic oil, which can be reused, reducing hydraulic oil waste. At the same time, it avoids oil leakage from contaminating other parts of the equipment and the working environment, creating a clean and safe working environment for employees. The early warning device can detect oil leakage problems in time, reducing equipment downtime for maintenance due to oil leakage, improving workshop synthesis efficiency, and reducing the loss of manpower and material resources caused by equipment component damage, effectively controlling production costs.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-5 This utility model is a device for preventing oil leakage from the guide sleeve and providing early warning for a hinged six-sided top press. It includes a body 1, a guide sleeve 2 fixedly connected to the bottom of the body 1, a piston 3 provided at the bottom of the guide sleeve 2, an oil leakage early warning component 4 provided on the surface of the piston 3, the oil leakage early warning component 4 including a sealing sleeve 41, the sealing sleeve 41 being fitted at the connection between the guide sleeve 2 and the piston 3, an oil guide pipe 42 provided on one side of the bottom of the sealing sleeve 41, an oil tank 43 connected to one side of the oil guide pipe 42, and a proximity switch 44 provided on one side of the top of the oil tank 43.

[0028] Specifically: Under the constraint of the guide sleeve 2, the piston 3 reciprocates along a preset trajectory inside the cylinder of the six-sided top press. The oil guide pipe 42 is routed to fit the equipment structure layout. A float is installed inside the oil tank 43, which floats freely with the rise and fall of the oil level in the tank. When the amount of leaked oil collected in the tank 43 gradually increases and the oil level rises to a preset warning position, the float will rise synchronously with the oil level and approach the proximity switch 44. After sensing the float, the proximity switch 44 immediately issues a warning signal to inform the operator that there is oil leakage in the guide sleeve 2 and that the amount of leakage has reached the threshold that needs to be addressed. The sealing sleeve 41 seals the connection between the guide sleeve 2 and the piston 3. The oil guide pipe 42 effectively guides and recovers leaking oil, preventing hydraulic oil from seeping into the large and small pads and preventing them from cracking due to long-term contact with hydraulic oil. This ensures equipment alignment, reduces the risk of damage to the carbide top hammer 9, and prevents hydraulic oil from dripping onto the pyrophyllite blocks, preventing impurities from being mixed into the synthesis cavity and ensuring the synthesis quality of superhard materials. The early warning mechanism formed by the proximity switch 44 can send a signal in time when the amount of leaking oil reaches the warning line, greatly increasing the probability of detecting oil leakage in the upper cylinder guide sleeve 2. The oil tank 43 centrally recovers leaking oil, allowing the recovered hydraulic oil to be reused after processing, reducing hydraulic oil waste and lowering production costs.

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, a hinge beam 5 is fixedly connected to the surface of the body 1. A pin hole 6 is opened on one side of the hinge beam 5. A positioning sleeve 7 is fixedly connected to the bottom of the guide sleeve 2. An internal hex bolt 8 is threadedly connected to the bottom of the positioning sleeve 7. A top hammer 9 is provided on one side of the piston 3. One side of the top hammer 9 is fixedly connected to the piston 3 by fasteners. The sealing sleeve 41 has a U-shaped structure and is made of silicone. A connector 10 is connected to one side of the bottom of the sealing sleeve 41. The bottom of the connector 10 is connected to the oil guide pipe 42. There are four sets of hinge beams 5, which are symmetrically arranged.

[0031] Specifically: The six hinge beams 5 are hinged together by passing a pin through the pin hole 6, thus integrating the six working cylinders into a cohesive whole. The positioning sleeve 7, in conjunction with the hexagonal socket bolt 8, positions the guide sleeve 2, ensuring that the guide sleeve 2 maintains a preset coaxiality with the piston 3 during installation and equipment operation. The top hammer 9 is fixedly connected to the piston 3 with fasteners, ensuring a firm connection between them and preventing relative displacement or loosening under high pressure. The sealing sleeve 41 adopts a U-shaped structure design, forming a more closely fitting, enveloping seal at the connection between the guide sleeve 2 and the piston 3, maximizing the collection of hydraulic oil leaking from the connection. To improve the integrity of oil leakage collection, the good elasticity and sealing properties of silicone enhance the sealing effect and reduce the leakage in the early stage of oil leakage. At the same time, it has good high temperature resistance and can adapt to the high temperature working environment in the process of superhard material synthesis. The connector 10 can provide a transition interface for the connection between the sealing sleeve 41 and the oil guide pipe 42, avoiding the pipe bending problem when the oil guide pipe 42 is directly connected to the sealing sleeve 41. The four sets of symmetrically arranged hinge beams 5 can make the overall structure of the six-sided top press more balanced and symmetrical, and evenly distribute the stress generated under high pressure to the four sets of hinge beams 5, avoiding fatigue damage to the local hinge beams 5 due to excessive stress, and extending the service life of the hinge beams 5.

[0032] The working principle of this utility model is as follows: A U-shaped sealing sleeve 41 made of silicone material is fitted at the connection between the guide sleeve 2 and the piston 3. Its U-shaped opening is aligned with the gaps where oil leakage may occur, forming a wrap-around seal, thereby firmly confining the oil leakage inside the sealing sleeve 41 and preventing hydraulic oil from dripping directly or seeping into other areas of the equipment. The connector 10 provides a transition interface for oil leakage discharge, avoiding the problem of pipeline bending when the oil guide pipe 42 is directly connected to the sealing sleeve 41. The pipeline route of the oil guide pipe 42 conforms to the structural layout of the equipment. The oil leakage is directed to the oil tank 43 through the oil guide pipe 42, realizing the centralized recovery of the oil leakage.

[0033] As the leaking oil continues to flow into the oil tank 43, the oil level gradually rises, and the float floats upward in sync. When the oil level rises to the preset warning threshold, the float approaches the proximity switch 44, triggering the sensing mechanism of the proximity switch 44. The proximity switch 44 then issues a warning signal, indicating to the staff that the guide sleeve 2 has leaked oil and that the amount of oil leaking needs to be dealt with in a timely manner to prevent the oil leaking problem from expanding further.

[0034] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
