Description

technical field [0001] The invention belongs to the technical field of superhard material synthesis processing equipment, and in particular relates to a hinged beam assembly and a new six-sided top press. Background technique [0002] Synthetic diamond is formed by changing the lattice structure of graphite crystal under high temperature and high pressure environment. It is a functional material widely used in cutting-edge fields such as aerospace, high-end medical treatment, and power electronics. According to statistics, China's diamond production has accounted for more than 90% of the world's total, but its quality is still low and mid-range internationally, and there is still a certain gap compared with foreign synthetic diamond grades. The hinged six-sided top press is the main equipment of superhard material synthetic diamond with independent intellectual property rights in my country. It has the advantages of low equipment cost, simple operation and low production cos...

Problems solved by technology

[0004] In terms of improving the pressure level of the six-sided press, the main method is to increase the bore diameter of the hinge beam and improve the system pressure level. At present, the diameter of the largest six-sided press in China has reached 1000mm, and the system pressure has reached 100Mpa. However, limited by the hinge beam structure and oil cylinder sealing characteristics of the six-sided press, the development in this direction is close to the limit, and the room for development and improvement is very small; In terms of pressure stability, the main measures taken are to improve the hydraulic system and enhance the synchronous control accuracy of the system. However, due to the sealing effect of the oil cylinder of the six-sided top press and the characteristics of the large flow of hydraulic oil in the oil cylinder, it is very difficult to improve the pressure control. Large and unsatisfactory; in terms of prolonging the life of hinge beam components and reducing the weight of the system, for example, the main development direction of the documents with application numbers 201811153837.4 and 201220640880.5 is to replace the traditional cast hinge beam with a forged hinge beam and optimize the structure of the hinge beam

However, as the cylinder diameter of the six-sided top press continues to increase and the pressure of the press gradually increases, the unit weight of the hinged beam will inevitably increase, which brings great difficulty to the forging and processing of the hinged beam. There is already little room for improvement in press weight
