Description

Technical Field

[0001] This utility model belongs to the field of top press technology, specifically relating to a top pressing structure of a large six-sided top press. Background Technology

[0002] Large-cavity presses include two-sided presses and multi-sided pressing chamber devices. Multi-sided pressing chamber devices include tetrahedral presses, hexahedral presses, and octahedral presses. Among them, tetrahedral presses are basically no longer used. Hexahedral presses are further divided into hinged type and tie rod type. The hexahedral press is the most widely used large-cavity press in China. This type of press has the advantages of strong self-centering, low cost, and easy operation. It is the main equipment for synthesizing superhard materials such as diamond and cubic boron nitride in China. The hexahedral press has 6 working cylinders, and the first-stage pressurization can reach 8GPa. The second-stage 6-8 die pressurization device is directly placed in its hexahedral pressing chamber to form an octahedral pressing chamber. The maximum pressure can reach 25GPa and the maximum temperature can reach 2500℃. During the operation of the hexahedral press, the output end of the working cylinder will carry out oil sludge during the movement. Due to the high temperature of the working environment, the oil sludge will flow into the inside of the equipment and the surface of the hammer, thus contaminating the processed parts.

[0020] In this embodiment: the main structure consists of a hinged beam 1, several connecting plates 11, a working cylinder 12, a piston rod 121, and a hammer head 13. The working cylinder 12, piston rod 121, and hammer head 13 form the main structure. The working cylinder 12 and piston rod 121 drive the hammer head 13 to extrude the workpiece. A connecting housing 2 is provided on the outside of the piston rod 121. A first connecting part 21 and a second connecting part 22 are respectively provided at both ends of the connecting housing 2. The connecting housing 2, the first connecting part 21, and the second connecting part 22 form a sealing element that connects the working cylinder 12 and the hammer head 13. A sealing ring 3 is detachably connected to one side. The connecting housing 2 is fixed to the sealing ring 3 via the first connecting part 21. The sealing ring 3 enhances the sealing effect between the connecting housing 2 and the hammer head 13. A connecting frame 4 is provided at one end of the working cylinder 12. The connecting housing 2 is fixed to the connecting frame 4 via the first connecting part 21. The connecting frame 4 enhances the sealing effect between the connecting housing 2 and the working cylinder 12. When installing this structure, the sealing ring 3 is installed in the connecting groove 31 at one end of the hammer head 13. The second connecting part 22 and the sealing ring 3 are then connected via the mounting parts. The connecting parts are fixed together, so that the second connecting part 22 is connected and fixed to the sealing ring 3 and the hammer head 13. The connecting frame 4 is installed at one end of the working cylinder 12 by the fixing member 41, and the connecting frame 4 is sleeved on the outside of the piston rod 121. The first connecting part 21 is sleeved on one end of the connecting frame 4. The fixing member 41 connects and limits the connection between the first connecting part 21 and the connecting frame 4. During the extension and retraction of the piston rod 121, the connecting housing 2 extends and retracts with the piston rod 121. During the movement of the piston rod 121, the sludge generated between the piston rod 121 and the working cylinder 12 will be discharged from the working cylinder. The oil sludge flows out from one end of the cylinder 12. By setting the connecting housing 2, the flow range of the oil sludge is limited, so that the oil sludge flowing out from the output end of the working cylinder 12 is stored inside the connecting housing 2, which prevents the oil sludge from adhering to the working cylinder 12 and causing contamination to the workpiece. It also prevents the oil sludge from being difficult to clean after processing, which would lead to the problem of oil sludge contamination inside the press. The sealing assembly composed of the connecting housing 2, the first connecting part 21, the second connecting part 22, the sealing ring 3, and the connecting frame 4 isolates the oil sludge from the hammer head 13, making it easier to clean the oil sludge in a centralized manner and reducing contamination to the workpiece.

[0021] The first connecting part 21 and the second connecting part 22 are respectively fixedly connected to both ends of the connecting housing 2, and the first connecting part 21 and the second connecting part 22 are both integrally formed with the connecting housing 2. The connecting housing 2 is integrally formed with the first connecting part 21 and the second connecting part 22, and the connection effect between the first connecting part 21 and the connecting frame 4 and the second connecting part 22 and the sealing ring 3 is maintained during the deformation of the connecting housing 2.

[0022] A connecting groove 31 is provided on one side of the hammer head 13. The sealing ring 3 matches the shape of the connecting groove 31, and the sealing ring 3 and the connecting groove 31 are engaged and connected. By setting the sealing ring 3 and the connecting groove 31, it is convenient to connect the second connecting part 22, increase the sealing effect between the hammer head 13 and the connecting housing 2, and prevent sludge from flowing to the surface of the hammer head 13.

[0023] The connecting frame 4 is sleeved on the outside of the piston rod 121, and the first connecting part 21 is sleeved on one end of the connecting frame 4. The first connecting part 21 and the connecting frame 4 are installed and fixed by the fastener 41. The connecting housing 2 is installed and fixed to the connecting frame 4 through the first connecting part 21. The connecting frame 4 increases the sealing effect between the connecting housing 2 and the working cylinder 12.

[0024] The connecting housing 2 is sleeved on the outside of the piston rod 121, and both ends of the connecting housing 2 are set as open structures. By setting the connecting housing 2, the flow range of the sludge is limited, so that the sludge flowing out from the output end of the working cylinder 12 is stored inside the connecting housing 2.

[0025] The second connecting part 22 is installed and fixed to the sealing ring 3 and the hammer head 13 through the mounting part, and the second connecting part 22 is tightly fitted to one side of the sealing ring 3; the second connecting part 22 and the sealing ring 3 are connected and fixed through the mounting part, so that the second connecting part 22 is connected and fixed to the sealing ring 3 and the hammer head 13.

[0026] The hammer head 13 is detachably connected to one end of the piston rod 121, and the piston rod 121 is slidably connected inside the working cylinder 12. The detachable connection between the hammer head 13 and the piston rod 121 facilitates the disassembly and assembly of the sealing assembly consisting of the connecting housing 2, the first connecting part 21, the second connecting part 22, the sealing ring 3, and the connecting frame 4, thereby facilitating the cleaning of its interior.

[0027] The working principle and usage process of this utility model are as follows: During installation, the sealing ring 3 is installed in the connecting groove 31 at one end of the hammer head 13. The second connecting part 22 and the sealing ring 3 are connected and fixed using the mounting components, thus connecting and fixing the second connecting part 22 to the sealing ring 3 and the hammer head 13. The connecting frame 4 is installed at one end of the working cylinder 12 via the fixing component 41, and the connecting frame 4 is sleeved on the outside of the piston rod 121. The first connecting part 21 is sleeved on one end of the connecting frame 4. The fixing component 41 connects and limits the connection between the first connecting part 21 and the connecting frame 4. During the extension and retraction of the piston rod 121, the connecting housing 2 extends and retracts along with the piston rod 121. During the movement of the piston rod 121, the sludge generated between the piston rod 121 and the working cylinder 12 will flow out from one end of the working cylinder 12. By setting the connecting housing 2, the flow range of the sludge is limited, so that the sludge flowing out from the output end of the working cylinder 12 is stored inside the connecting housing 2, avoiding the sludge from adhering to the working cylinder 12 and causing contamination to the workpiece. This prevents the sludge from being difficult to clean after processing, thus avoiding the problem of the press being contaminated with sludge inside and difficult to clean.
