Description

Technical Field

[0001] The utility model belongs to the technical field of preheating blocks, and in particular relates to a diamond indirect heating type preheating block. Background Art

[0002] At present, the six-sided top press is the main equipment for manufacturing superhard materials such as diamond and cubic boron nitride in my country. The top hammer on the press is not only a key component for transmitting and expanding pressure when synthesizing superhard materials, but also plays an important role in cooperating with pyrophyllite sealing. The main principle of the sealing of the working chamber of the domestic six-sided top press is: the ultra-high pressure generated by the six cemented carbide top hammers acts on the internal synthetic block. The synthetic block is a cubic workpiece assembled with pyrophyllite as the pressure transmission medium. After being subjected to ultra-high pressure, the pyrophyllite on the surface is squeezed into the gap of the inclined surface of the cemented carbide top hammer. The inclined surface of the domestic cemented carbide top hammer has an inclination angle of 41-42°, which squeezes and rubs against the inclined surface of the top hammer to form a pyrophyllite sealing edge, maintaining the ultra-high pressure in the working chamber. Therefore, the friction between the pyrophyllite sealing edge and the inclined surface of the cemented carbide top hammer determines the sealing and pressure of the working chamber. The inclined surface of the top hammer used in the six-sided top press is a smooth plane with a small friction coefficient with pyrophyllite. The press needs to provide a large positive pressure to the contact surface of the sealing edge to increase the friction and ensure the sealing of the working chamber. Therefore, part of the pressure transmitted by the top hammer is lost on the pyrophyllite sealing edge, which reduces the pressure in the working chamber. A diamond indirect heating preheating block is needed to increase the positive pressure and friction. Utility Model Content
