| 摘 要： | 勘探用金刚石钻头在钎焊烧结过程中，钻头芯模、外模和钢体的尺寸直接决定金刚石钻头的尺寸，对金刚石钻头的使用性能影响很大，而现有的文献中对于模具尺寸设计的研究稍显不全面。对钻头钎焊烧结过程的热涨与冷缩过程进行深入分析研究，提出了更直观的模具计算公式和防止涨模的措施。

| Abstract: | In the brazing-sintering process of the exploration diamond bit, the dimensions of the core mould, outer mould and the steel body directly determine that of the diamond bit and have a great influence on the use performance of diamond bit, while the study on the mould dimension design is not comprehensive in the existing literature.By the detailed research on heating and cooling process in the bit brazing-sintering, a set of more intuitive calculation formulae of mould dimension design and the methods to prevent mould from expanding crack are built up. |
