Description
Technical Field
The invention relates to the technical field of artificial synthetic diamond and superhard materials, in particular to a three-module type hexahedral press.
Background
Diamond is a superhard material formed in nature through high temperature and high pressure in the subsurface for hundreds of millions of years, and is a natural diamond with large volume. After the industrial machinery can realize high-temperature and high-pressure equipment, artificial diamond synthesis can be realized finally, and the technology starts from a double-sided top technology and develops a six-sided top technology. The existing hinged hexahedral top diamond synthesis press is composed of 6 hinge beam cylinders with three-dimensional axes perpendicular to each other and bearing ultrahigh pressure, and the synthesis equipment with hydraulic cylinder for applying pressure to the center is the main machine type of ultrahigh pressure synthetic materials such as synthetic diamond, cubic boron nitride, etc. With the continuous improvement of equipment capability and the progress of process technology in recent years, the Clar-grade diamond, namely the artificial diamond, can be cultivated.
The demands of superhard materials such as industrial diamond, cubic boron nitride and the like continuously rise, artificial cultivation of diamond is in progress, and new requirements are put on comprehensive performances such as hexahedral pressure, temperature, stability, geometric precision and the like. The press structure is a hexahedral base, and the hexahedral hydraulic press utilizes the working principle that 6 orthogonal surfaces simultaneously act on a receptor, pushes 6 hard alloy top hammers synchronously by hydraulic pressure to squeeze and push a synthetic material receptor along the orthogonal direction to generate high pressure, and heats the synthetic material receptor by low voltage and high current to achieve high temperature, so that the internal tissue of the synthetic material is subjected to specific reaction to form a new superhard material.
The hexahedral top main body frame for practical industrial production is provided with 6 hinge beams, and is connected into a whole through 12 pins through the lugs (3 rib plates and 2 rib plates are respectively in a pair). The 6 hydraulic cylinders are respectively arranged in the through holes in the middle of the hinge beam and are driven by pressure to move in opposite directions to apply acting force to the central synthetic material. The biggest challenge of a hexahedral operation is that 6 force centers intersect at a point, the center point, which is also the geometric center point of the receptor.
With the improvement of the hexahedral top performance requirement, the volume of the equipment is increased, and taking a 850 mm cylinder diameter cast hinge beam as an example, the length and the width of a single hinge beam are more than two meters, the weight of the single hinge beam can reach 10 tons after a working cylinder and a piston are installed, the weight of the whole machine can reach 80 tons, the structure of the hinge beam is relatively complex, the single beam comprises precise machining of a central cylinder hole, precise machining of 4 hinge holes and end face machining, the directions of 5 holes are three-dimensional orthogonalization, the requirement on precise machining form and position tolerance is high, and the machining difficulty is high. Because the number of hinge beams is up to 6, the number of pins is more than 12, space precision is limited, and the assembly interference can exist, so that the assembly difficulty is higher, and the assembly and maintenance are long. Under the superposition of a plurality of adverse factors, the problem that the axes of 6 hydraulic cylinder holes are difficult to intersect at one point, namely the equipment precision is poor, so that uneven stress is caused, and the problems of working cylinder damage or hinge quantity breakage and the like are easy to occur.
Therefore, how to provide a novel hexahedral press with high precision and simple structure is a problem to be solved urgently by those skilled in the art.
