摘要
文章针对普通钎焊的聚晶金刚石钻头剪切强度不高,提出了采用单片机加压控制的PCD复合片真空扩散焊接的设计思想,在对原真空扩散焊机液压改造的基础上给出如何由单片机控制加压的电路和程序流程设计。实际应用表明,该技术经济实用,有较好的经济效益。
As shear strength of polycrystalline diamond compact bit ,which is made of ordinary braze welding, is not high, a new kind of design thought of using microcontroller to pressurize and control the PCD compound piece in vacuum diffusion bonding is proposed. On the basis of transformation hydraumatic system of original vacuum proliferation welding machine, pressurized circuit controls by microcontroller and program process is designed. The practical application indicates that this technique is economical and practical and yield good economic returns.
