Description

Technical Field

[0001] The utility model relates to the technical field of six-sided top press machines, in particular to a six-sided top press machine limit block structure. Background Art

[0002] In recent years, as the price of artificial diamonds has been falling, the diamond industry has become more and more demanding on cost control. In order to reduce the cost per carat, in addition to conventional management methods, developing a six-sided top press with a larger cylinder diameter is one of the most effective methods.

[0003] The six-sided top press is the most widely used large-cavity press in China. This type of press has the advantages of strong self-centering, low cost, and easy operation. It is the main equipment for synthesizing superhard materials such as diamond and cubic boron nitride (CBN) in China. The existing six-sided top press is composed of six hinged beams that are hinged to each other through beam ear holes and pin shafts. During the use of the six-sided top press, the hinge beam ears are prone to tearing. In order to improve the tensile properties of the hinge beam ears and further improve the pressure resistance of the six-sided top press, one of the existing feasible operating methods is to set a frame outside the six-sided top press, and limit the six-sided top press through the frame to improve the pressure resistance of the six-sided top press. However, the six-sided top press itself is already very large, and setting up the frame requires a large amount of steel, as well as increasing the floor space of the equipment and increasing production costs.
