Abstract:

In order to overcome the disadvantages of the processing difficulties and high consumption of tungsten carbide cylinder， a novel split-type ultra-high pressure die（STD） is designed according to the principle of mass support and lateral support， which has the advantages of higher limit pressure capacity and larger cavity volume. The STD cylinder is composed of a plurality of cemented carbide sections， without using large-size cemented carbide， effectively reducing the circumferential stress of the cylinder and obtaining greater chamber pressure. The stress of STD cylinder is analysed by numerical simulation. The results show that the stress of STD cylinder is obviously less than that of belt type ultra-high pressure die （BTD） cylinder， and the stress decreases gradually with the increase of the number of split blocks. After the cylinder is split， the stress of the support ring does not change significantly， which can ensure that the pressure cylinder can obtain sufficient and effective pre-tightening. Based on the maximum distortion energy theory and the maximum shear stress theory， the ultimate pressure bearing capacity of the ultra-high pressure die was evaluated. The pressure bearing capacity of STD was obviously greater than that of BTD cylinder， and the more the number of split blocks of the cylinder， the stronger the pressure bearing capacity. The destructive experiment further verifies that the pressure bearing capacity of STD is better than that of BTD， and the split block of the pressure cylinder can be replaced separately after damage， which can effectively reduce the use cost.
