Description

Technical Field

[0001] The utility model belongs to the technical field of superhard material synthesis, in particular to a six-sided top press device for superhard material synthesis. Background Art

[0002] The hinged six-sided press, a machine independently developed in my country for producing synthetic diamonds, has contributed significantly to the development of the synthetic diamond industry in China and around the world. Since its introduction, my country's superhard material production has grown exponentially. However, after decades of development, the heavy loads exerted by the six-sided press during operation have made it prone to production accidents and posed significant safety risks.

[0003] During the use of the six-sided top press, a high-temperature and high-pressure growth environment is required for diamond synthesis, with the maximum pressure reaching 100Mpa. The high-pressure working environment also brings many safety hazards. For example, the six-sided top press will suffer fatigue damage in the main pressure-bearing parts such as the hinge beam and working cylinder under long-term cyclic high-pressure loads. Under high-pressure conditions during use, they may suddenly break, causing accidents; during use, the weak joints of the high-pressure oil pipes may rupture, causing high-pressure oil leakage, causing accidents; during use, the diamond synthesis block will be deformed and compressed during the extrusion process, causing the block to separate and splash, causing accidents; the hinge beam of the six-sided top press is connected by a pin rod. If the gap between the pin hole is large, the pin rod will loosen and cause the pin rod to fall off, causing accidents. Utility Model Content

[0004] The utility model aims to provide a six-sided top press device for superhard material synthesis, which solves the problem in the prior art that when the six-sided top press is in operation, the pin rod becomes loose and causes the pin rod to fall off.

[0005] The technical solution adopted by the utility model is a six-sided top press device for superhard material synthesis, which includes a six-sided top press body. The six-sided top press body is equipped with multiple hinge beams, the multiple hinge beams are connected by pin rods, the hinge beams are connected to multiple beam bottom guard belts, and the pin rods are connected to pin rod guard belts.

[0006] The utility model is also characterized in that:

[0007] A threaded hole is opened at the bottom of the hinge beam, and multiple beam bottom guards are connected to the hinge beam through screws.

[0008] The pin rod is provided with a threaded hole, and the pin rod guard band is connected to the pin rod by screws.

[0009] The six-sided top press body is connected with a high-pressure oil pipe, and the high-pressure oil pipe is covered with an oil pipe shield.

[0010] The side wall of the six-sided top press body is provided with a plurality of beam bottom displacement sensors.

[0011] The six-sided top press body is connected with a protective baffle through a connecting rod mechanism, and the protective baffle is arranged on the outer wall of the six-sided top press body.

[0012] The beneficial effects of the utility model are as follows:

[0013] The six-sided top press device for superhard material synthesis provided by the utility model, by setting the beam bottom belt, pin rod belt, oil pipe shield, protective baffle and beam bottom displacement sensor, firstly reduces the risk during the use of the six-sided top press, and secondly prevents the fracture of cracks, improving the safety of the six-sided top press during use.

[0017] The utility model will be described in detail below in conjunction with the drawings and specific embodiments.

[0018] The utility model provides a six-sided top press device for superhard material synthesis, as Figure 1 shown, which includes a six-sided top press body 1. The six-sided top press body 1 is connected with a hinge beam 2 through a pin rod. Threaded holes are opened at the bottom of the hinge beam 2. 8 beam bottom belts 3 are used at the bottom of the hinge beam 2 and are fastened by screwing into the threaded holes at the bottom of the hinge beam 2. During the long-term use of the hinge beam 2, the beam ear part of the hinge is prone to fatigue fracture. Once it suddenly breaks, the beam bottom belt 3 can be used for buffering to reduce the safety risk.

[0019] Secondly, threaded holes are opened at the upper and lower end faces of the pin rod. 8 pin rod belts 5 are used and are fastened by screwing into the threaded holes at the upper and lower end faces of the pin rod. Since the pin rod and the hinge beam are in clearance fit and there is a risk of detachment, the pin rod belts 5 are used to connect both ends of the pin rod to prevent the pin rod from detaching and slipping. At the same time, the pin rod belt can also play a protective role when the ear of the press hinge beam 2 suddenly breaks, preventing the ear piece from flying out and causing a safety accident.

[0020] Secondly, the high-pressure oil pipe of the six-sided top press is connected from the bottom of the hinge beam 2. The oil pipe shield 4 protects the six-sided top press body 1 from the splashing of high-pressure oil during use. 5 oil pipe shields 4 are used for the six-sided top press body 1. When there is a leakage or fracture of the high-pressure oil pipe, the high-pressure oil will not splash out, thus playing a protective role.

[0021] Secondly, there are four windows on the cubic press for operation and maintenance. The protective baffle 6 is connected to the piston of the cubic press body 1 through a linkage mechanism. When the cubic press body 1 is running, the synthesis cavity is closed, and the piston moves to close the protective baffle, preventing the block from separating and splashing out during the extrusion deformation of the diamond synthesis block. When the cubic press body 1 stops, the synthesis cavity is opened, the piston returns, and the protective baffle is opened for operation and maintenance.

[0022] As Figure 2 shown, the beam bottom displacement sensor 7 is placed on the bottom surface of the side beam of the cubic press body 1 at a position 50 mm away through a bracket. The beam bottom displacement sensor is used to monitor the displacement of the bottom part of the hinge beam 2, and provides an alarm signal when cracks appear at the bottom and the displacement increases. Eight beam bottom displacement sensors 7 are installed at the bottom of the hinge beam 2, and the signals are connected into the control system of the cubic press for real-time monitoring. A limit value is set for each beam bottom displacement sensor, and an alarm signal is provided when the displacement exceeds this value, preventing the crack from continuing to extend and causing greater damage to the cubic press.
