Description

Technical Field

[0001] This invention relates to the field of top press technology, and specifically to a six-sided top press structure. Background Technology

[0002] The six-sided top press is a large-cavity press that uses hydraulic power to drive three pairs of mutually perpendicular top hammers to simultaneously apply ultra-high pressure and high temperature to a cubic composite block. It has advantages such as strong self-centering, low cost, and easy operation. It is the mainstream equipment for synthesizing superhard materials such as synthetic diamond and cubic boron nitride in industry. It converts carbon sources (such as graphite) into diamond crystals by directly applying pressure.

[0003] However, in existing six-sided top presses, the hydraulic oil pipes are directly connected to the oil inlet by connecting parts and flanges mounted on the hinge beam. The flanges are only fixed to the hinge beam with bolts, which are easily affected by equipment vibration and can rotate, causing the flanges and the oil pipe connections mounted on them to loosen, resulting in hydraulic oil leakage. Therefore, there is an urgent need for a six-sided top press structure that can prevent flange loosening and thus avoid hydraulic oil leakage. Summary of the Invention

[0004] The purpose of this invention is to provide a six-sided top press structure, which uses anti-detachment plates and anti-rotation plates to lock the flange, preventing the flange from rotating and shaking on the hinge beam, improving the stability of the flange and its oil pipe connections, avoiding hydraulic oil leakage caused by the flange pulling the oil pipe connections loose, and reducing the impact of equipment vibration on the hydraulic pipeline, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A six-sided top press structure includes: six hinged beams connected to each other and flanges mounted on their backs. Each hinge beam has an oil inlet hole communicating with its inner cavity on its back. The flange is positioned at the oil inlet hole for installing oil pipe connectors. A mounting groove is formed around the outside of the oil inlet hole on the back of the hinge beam. The flange is installed within the inner cavity of the mounting groove. An anti-loosening assembly is provided between the flange and the inner wall of the mounting groove. The anti-loosening assembly includes a connecting pipe, an anti-detachment plate, and an anti-rotation plate. The connecting pipe is located inside the flange and inserted into the oil inlet hole, communicating with it. The anti-detachment plate and the anti-rotation plate are sequentially mounted on the outer wall of the connecting pipe and are used to prevent the flange from loosening, falling off, or rotating.

[0007] As a further embodiment of the present invention: the connecting pipe is welded to the inside of the flange, the inner wall of the oil inlet hole is provided with a sealing step surface, the connecting pipe is inserted into the inner cavity of the oil inlet hole and closely attached to the end face of the sealing step surface, and a sealing ring is provided between the connecting pipe and the end face of the sealing step surface.

[0008] As a further embodiment of the present invention: the inner wall of the mounting groove is provided with a groove communicating with the outside of the oil inlet hole, and a number of circumferentially distributed limiting protrusions are provided at the middle position of the inner wall of the groove, and there is a clamping groove between the lower part of the limiting protrusions and the bottom of the inner cavity of the groove.

[0009] As a further embodiment of the present invention: the anti-detachment plate is composed of several splined plates spliced ​​together. The several splined plates are installed in a circle on the outer wall of the connecting pipe at the end away from the flange. The several splined plates are respectively inserted into the groove and rotated into the clamping groove to be tightly attached to the lower end face of the limiting protrusion.

[0010] As a further embodiment of the present invention: the anti-rotation plate has a through hole on its end face, and the anti-rotation plate slides on the outer wall of the connecting pipe through the through hole and is located between the spline plate and the flange. Furthermore, a number of sliders are evenly arranged on the inner wall of the through hole, and a sliding groove is provided at the position corresponding to the slider on the outer wall of the connecting pipe. The slider is slidably installed inside the sliding groove, and a spring for adjusting its position is provided between the end face of the anti-rotation plate and the inner end face of the flange and around the outside of the connecting pipe.

[0011] As a further aspect of the present invention: anti-rotation grooves are provided at the positions corresponding to the end face of the anti-rotation plate and several spline plates. The anti-rotation plate surrounds the outside of the limiting protrusion through the anti-rotation groove and is inserted into the gap between two adjacent limiting protrusions.

[0012] As a further embodiment of the present invention: a number of locking bolts are evenly arranged on the outer end face of the flange, and the locking bolts pass through the flange and are threadedly installed inside the hinge beam.

[0013] Compared with the prior art, the advantages of the present invention are as follows:

[0014] By installing anti-loosening components, the connecting pipe on the flange end face is inserted into the oil inlet hole, allowing the anti-detachment plate on the outer wall of the connecting pipe to move into the bottom of the groove. The flange is then rotated, causing each spline plate on the anti-detachment plate to rotate below the limiting protrusion. The limiting protrusion restricts the position of the spline plates, preventing the flange from shaking or falling off the hinge beam. Simultaneously, the anti-rotation plate rotates above the limiting protrusion along with the flange's rotation and, under the force of a spring, inserts into the gap between two adjacent limiting protrusions. This achieves anti-rotation limiting of the flange, improving the stability of the flange and its oil pipe connections, preventing hydraulic oil leakage caused by the flange loosening the oil pipe connections, and reducing the impact of equipment vibration on the hydraulic pipeline.

[0023] Combination Figures 1-6 As shown in this embodiment, a six-sided top press structure includes: six hinged beams 1 connected to each other and flanges 2 installed on their backs. The back of the hinge beams 1 is provided with oil inlet holes 101 that communicate with their inner cavities. The flanges 2 are set at the oil inlet holes 101 for installing oil pipe connectors. The hydraulic pump draws hydraulic oil from the oil tank and pressurizes it, allowing the hydraulic oil to flow through the hydraulic pipeline and the oil inlet holes 101 into the inner cavity of the hinge beams 1 to drive the piston and top hammer displacement, thereby achieving top pressing on the workpiece.

[0024] In this embodiment, the back of the hinge beam 1 is provided with an installation groove 102 around the outside of the oil inlet hole 101. The flange 2 is installed in the inner cavity of the installation groove 102. A number of locking bolts 25 are evenly arranged on the outer end face of the flange 2. The locking bolts 25 pass through the flange 2 and are threaded inside the hinge beam 1. The flange 2 is fixed inside the installation groove 102 by the locking bolts 25, thereby locking the flange 2 and further improving the stability of the flange 2.

[0025] In this embodiment, the connecting pipe 21 is welded to the inner side of the flange 2, and the inner wall of the oil inlet hole 101 is provided with a sealing step surface 12. The connecting pipe 21 is inserted into the inner cavity of the oil inlet hole 101 and closely attached to the end face of the sealing step surface 12. A sealing ring is provided between the connecting pipe 21 and the end face of the sealing step surface 12. The connecting pipe 21 is inserted into the inner cavity of the oil inlet hole 101, so that the connecting pipe 21 presses the sealing ring on the sealing step surface 12, thereby achieving a seal between the flange 2 and the hinge beam 1.

[0026] In this embodiment, the inner wall of the mounting groove 102 is provided with a groove 103 that communicates with the outside of the oil inlet hole 101. Several circumferentially distributed limiting protrusions 11 are provided at the middle position of the inner wall of the groove 103. There is a clamping groove between the lower part of the limiting protrusions 11 and the bottom of the inner cavity of the groove 103. The spline plate 22 is driven by the connecting pipe 21 to be inserted into the bottom of the inner cavity of the groove 103 through the gap between two adjacent limiting protrusions 11. At the same time, the rotating flange 2 drives the connecting pipe 21 and the spline plate 22 on its outer wall to rotate, rotating the spline plate 22 into the clamping groove and tightly abutting the lower end face of the limiting protrusion 11. The limiting protrusions 11 are used to limit the position of the spline plate 22, the connecting pipe 21, and the flange 2 to prevent the flange 2 from shaking or falling off on the hinge beam 1.

[0027] In this embodiment, the anti-rotation plate 23 has a through hole 232 on its end face. The anti-rotation plate 23 slides on the outer wall of the connecting pipe 21 through the through hole 232 and is located between the spline plate 22 and the flange 2. Furthermore, anti-rotation grooves 231 are provided at positions corresponding to several spline plates 22 on the end face of the anti-rotation plate 23. The anti-rotation plate 23 surrounds the outside of the limiting protrusion 11 through the anti-rotation groove 231 and inserts into the gap between two adjacent limiting protrusions 11. A spring 24 for adjusting its position is provided between the end face of the anti-rotation plate 23 and the inner end face of the flange 2, and surrounding the outside of the connecting pipe 21. The anti-rotation plate 23 rotates above the limiting protrusion 11 as the flange 2 rotates. Under the force of the spring 24, the anti-rotation groove 231 is fitted onto the outside of the limiting protrusion 11 and inserted into the gap between two adjacent limiting protrusions 11. The limiting protrusion 11 limits the position of the anti-rotation plate 23 and the flange 2, preventing the anti-rotation plate 23 and the flange 2 from rotating, thus achieving anti-rotation limiting of the flange 2 and further improving the stability of the flange 2 and its oil pipe connectors. Moreover, when the spline plate 22 is inserted into the bottom of the groove 103, there is an angular deviation between the anti-rotation groove 231 and the limiting protrusion 11, which allows the anti-rotation plate 23 to slide on the outer wall of the connecting pipe 21 after being blocked by the limiting protrusion 11, without interfering with the installation of the anti-detachment plate.

[0028] In this embodiment, a plurality of sliders 233 are evenly arranged on the inner wall of the through hole 232. A groove 211 is provided on the outer wall of the connecting pipe 21 at the position corresponding to the slider 233. The slider 233 is slidably installed inside the groove 211. The anti-rotation plate 23 slides on the outer wall of the connecting pipe 21 through the through hole 232 and drives the slider 233 to slide in the groove 211. The position of the anti-rotation plate 23 is limited by the cooperation of the slider 233 and the groove 211, so that the anti-rotation plate 23 rotates with the connecting pipe 21, which facilitates the installation of the anti-rotation plate 23.

[0029] The working principle of this invention is as follows: The six-sided top press structure proposed in this application, by setting an anti-loosening component, inserts the connecting pipe 21 on the end face of the flange 2 into the oil inlet 101, and allows the spline plate 22 on the anti-detachment plate on the outer wall of the connecting pipe 21 to be inserted into the bottom of the inner cavity of the groove 103 through the gap between two adjacent limiting protrusions 11. Then, rotating the flange 2 drives the connecting pipe 21 and the spline plate 22 on its outer wall to rotate, rotating the spline plate 22 into the clamping groove and tightly abutting the lower end face of the limiting protrusion 11. The limiting protrusion 11 is used to limit the position of the spline plate 22, the connecting pipe 21, and the flange 2, preventing the flange 2 from shaking or falling off on the hinge beam 1. At the same time, the anti-rotation plate 23 follows the flange. The disc 2 rotates above the limiting protrusion 11 and, under the force of the spring 24, passes through the anti-rotation groove 231, which is fitted onto the outside of the limiting protrusion 11 and inserts into the gap between two adjacent limiting protrusions 11. The limiting protrusion 11 limits the position of the anti-rotation plate 23 and the flange 2, preventing the anti-rotation plate 23 and the flange 2 from rotating, thus achieving anti-rotation limiting of the flange 2. Finally, the flange 2 is fixed inside the mounting groove 102 by the locking bolt 25, thereby locking the flange 2, improving the stability of the flange 2 and its oil pipe connectors, avoiding hydraulic oil leakage caused by the flange 2 causing the oil pipe connectors to loosen, and reducing the impact of equipment vibration on the hydraulic pipeline.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
