摘　　要：针对目前六面顶压机人工合成工业金刚石所使用的硬质合金顶锤重新进行锤面设计。经过设计,制作成品后进行测量,新锤面顶锤相比原先的增大了6.5%。设计新的工业单晶合成块结构,运用帕斯卡原理,对顶锤底面的实际压力值进行推导计算出新的合成块在合成过程中的设备所需油压,并且进行实际实验合成工业金刚石。对使用新型顶锤的六面顶压机在合成过程中测量六面顶压机梁耳处的形变量,对六面顶压机设备的安全性进行分析;对使用新型顶锤和原有顶锤所合成出的工业金刚石进行综合性评估及对比。实验结果显示新锤面顶锤合成工业金刚石在保证六面顶压机设备安全及金刚石质量稳定的情况下,金刚石产量增加约7.5%,经济效益明显增加。In the paper,the hammer surface of cemented carbide used in the synthesis of industrial diamond by six face press is redesigned.After the design and measurement of the product,the new hammer surface is increased by 6.5%to compare with the original one.A new structure of industrial single crystal synthetic block is designed.The actual pressure value of the bottom surface of the anvil is deduced by using Pascal principle.The oil pressure required by the equipment in the synthesis process of the new synthetic block is calculated,and the industrial diamond is synthesized by the actual experiment.In the paper,we have measured the deformation of the beam ear of the new type of anvil in the process of synthesis,have analyzed the safety of the equipment,and have comprehensively evaluated and compared the industrial diamond synthesized by the new type anvil and original anvil.The experimental result shows that under the condition of the safety ensurement of the equipment and the stability of the diamond quality,the output of diamond is increased by about 7.5%,and the economic benefit is obviously increased.
