Description

Technical Field

[0001] This utility model relates to the field of six-sided top press technology, specifically to a top hammer guide and positioning device for a six-sided top press. Background Technology

[0002] A six-sided press is a hydraulic device used for synthesizing superhard materials. It achieves material transformation by applying pressure in six directions and combining this with high-temperature conditions. The six-sided press is a core piece of equipment in the synthesis of superhard materials (such as diamond and cubic boron nitride) and high-pressure physics experiments. Its working principle involves six top hammers synchronously extruding the synthesis chamber along a three-dimensional coordinate axis, creating extreme working conditions of 3-8 GPa high pressure and 300-2000℃ high temperature. The top hammer guide and positioning device, as a key component connecting the top hammers to the press body, directly determines the coaxiality, displacement accuracy, and force uniformity of the top hammer movement. It is a crucial element in ensuring uniform pressure distribution in the synthesis chamber, preventing damage from uneven loading of the top hammers, and improving product yield.

[0003] The existing six-sided presses rely too heavily on simple displacement sensors for passive monitoring of the top hammer's guiding and positioning device. This device can only trigger a shutdown alarm when the deviation exceeds the limit, and cannot effectively guarantee the stability of guidance and positioning during actual operation. Utility Model Content

[0004] The purpose of this utility model is to provide a top hammer guide and positioning device for a six-sided top press, which has the advantage of stable guide and positioning. Even under high temperature and pressure, it can ensure the stability and guidance during movement. The stable guide and positioning effect is achieved through the cooperation of the added mechanical mechanism, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a top hammer guide and positioning device for a six-sided top press, comprising a base:

[0006] The top of the base is provided with a pressing mechanism for pressing processing, and the inner side of the pressing mechanism is provided with a guide mechanism for guiding the top hammer.

[0007] The top pressing mechanism includes an outer support assembly disposed on the top of the base and a hydraulic assembly connected to the outer support assembly. A connecting assembly and a positioning assembly connected to the connecting assembly are disposed on the outside of the hydraulic assembly.

[0008] The guiding mechanism includes a pressing component disposed at one end of the hydraulic component and a limiting component connected to the pressing component.

[0009] Preferably, the external support assembly includes a body bolted to the top of the base, and the inner side of the body has a connection hole.

[0010] Preferably, the hydraulic assembly includes a hydraulic cylinder installed inside the machine body, and a first connecting plate is fixedly installed on the outer side of the output end of the hydraulic cylinder.

[0011] Preferably, the connecting assembly includes a connecting seat fixedly installed on the outside of the first connecting plate, and a damper is fixedly installed on one side of the connecting seat.

[0012] Preferably, the limiting component includes a spring fixedly installed on one side of the connecting seat and a baffle fixed to one end of the spring. The baffle is fixed to one end of the damper, and the damper is located inside the spring.

[0013] Preferably, the pressing assembly includes a second connecting plate bolted to one side of the first connecting plate, and a hammer is fixedly installed on the inner side of the second connecting plate.

[0014] Preferably, the limiting component includes a fixed seat fixedly installed on the outside of the second connecting plate and a guide rod fixed to one side of the fixed seat, wherein a guide seat is fixedly installed at the end of the guide rod away from the fixed seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, through the coordinated arrangement of the pressing mechanism and the guiding mechanism, effectively achieves stable guidance and positioning. The hydraulic system in the pressing mechanism pushes the device in six directions. During this operation, whether extending or retracting, the guiding mechanism maximizes position control, thus achieving the desired positioning effect. The co-directional nature of the guiding mechanism and the hydraulic system in the pressing mechanism enhances the guiding effect during extension and movement, further improving guiding stability. This ensures that even under high temperature and high pressure conditions, the hammers in the six-sided pressing machine maintain their co-directional nature under hydraulic system drive, achieving the required guiding and positioning effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a top hammer guide and positioning device for a six-sided top press, including a base 1:

[0025] The top of the base 1 is provided with a pressing mechanism 2 for pressing processing, and the inner side of the pressing mechanism 2 is provided with a guide mechanism 3 for guiding the pressing hammer.

[0026] The pressing mechanism 2 includes an external support assembly disposed on the top of the base 1 and a hydraulic assembly connected to the external support assembly. A connecting assembly and a positioning assembly connected to the connecting assembly are disposed on the outside of the hydraulic assembly.

[0027] The guide mechanism 3 includes a pressing component located at one end of the hydraulic component and a limiting component connected to the pressing component.

[0028] Preferred:

[0029] like Figure 3 As shown, the external support assembly includes a body 21 bolted to the top of the base 1. A connection hole 22 is provided on the inner side of the body 21. The connection hole 22 facilitates the adaptation of the guide rod 34 and the guide seat 35, which can not only ensure the guidance during its movement, but also assist in achieving the positioning effect when the guidance is stable.

[0030] further:

[0031] like Figure 3As shown, the hydraulic assembly includes a hydraulic cylinder 24 installed inside the machine body 21. A first connecting plate 23 is fixedly installed on the outer side of the output end of the hydraulic cylinder 24. The hydraulic cylinder 24 is used to push the hammer body 32 to extend and move. Simultaneous movement on all six sides can be used to process the required materials. The first connecting plate 23 can not only be used to install the connecting seat 25 and its connected components, but also to install and fix the hammer body 32 for subsequent disassembly, maintenance or replacement.

[0032] in:

[0033] like Figure 4 As shown, the connecting assembly includes a connecting seat 25 fixedly installed on the outside of the first connecting plate 23. A damper 26 is fixedly installed on one side of the connecting seat 25. The arrangement of the first connecting plate 23 and the damper 26 can not only support the baffle 28, but also buffer and reduce the pushing force in the hydraulic system.

[0034] Going a step further:

[0035] like Figure 4 As shown, the limiting assembly includes a spring 27 fixedly installed on one side of the connecting seat 25 and a baffle 28 fixed to one end of the spring 27. The baffle 28 is fixed to one end of the damper 26. The damper 26 is located inside the spring 27. The function of the spring 27 is to assist it in resetting. After the extension positioning, the resetting operation can be performed according to its elasticity.

[0036] in addition:

[0037] like Figure 3 As shown, the pressing assembly includes a second connecting plate 31 bolted to one side of the first connecting plate 23. A hammer 32 is fixedly installed on the inner side of the second connecting plate 31. The hammer 32 can be installed and fixed between the second connecting plate 31 and the first connecting plate 23 by bolting. This method also facilitates subsequent disassembly, replacement and maintenance operations.

[0038] at last:

[0039] like Figure 3 As shown, the limiting component includes a fixed base 33 fixedly installed on the outside of the second connecting plate 31 and a guide rod 34 fixed to one side of the fixed base 33. A guide seat 35 is fixedly installed at the end of the guide rod 34 away from the fixed base 33. The fixed base 33 can be used to support the guide rod 34, while the guide rod 34 is set to install the guide seat 35, so as to ensure that the above structure can be adapted to the corresponding structure when it is driven to move, thereby achieving the guiding effect.

[0040] When the hydraulic system in the six-sided press is working, the hydraulic system here includes hydraulic cylinder 24. During the operation of the hydraulic cylinder 24, it will directly drive the hammer 32 connected to it to move in the same direction by pushing. During the operation, the hydraulic system in the six sides and the hammer 32 move synchronously, so that the six sides apply pressure to the placed material at the same time, and complete the processing operation under high pressure and high temperature.

[0041] Based on the above, when the hammer 32 moves, it directly drives the guide rod 34 and guide seat 35 to move through the fixed seat 33 bolted to the top. The guide rod 34 and guide seat 35 can move within their corresponding connecting holes 22. This mutual adaptation further improves and ensures the horizontality under hydraulic pressure, guaranteeing the stability of the guide. Simultaneously, to prevent excessive pushing from any of the six hammers 32, positioning is required. During the extension and pushing process, not only is passive detection by sensors as in existing technologies necessary... For measurement, mechanical assistance is needed for positioning. During movement, the guide seat 35 will gradually approach the baffle 28 during continuous displacement. The baffle 28, along with the damper 26 and spring 27, are used to position and block it. When the movement is excessive, it will directly contact the baffle 28 and compress the damper 26 and spring 27, further blocking it and controlling its position. When adjustment is needed, the baffle 28 will reset due to the elasticity of the spring 27. This method, combined with the above-mentioned guide structure, can effectively achieve stable guiding and positioning operations.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
