摘　　要：硬质合金头脱落是矿用镐形截齿失效的主要表现形式之一,脱落的主要原因与钎焊层的钎焊质量有关。模拟并分析钎焊层厚度对截齿整体力学性能的影响规律,得出合理的钎焊层厚度范围,对截齿生产制造工艺的改进具有一定的参考意义。Carbide head off is one of the main manifestations of mining pick-shaped picks,and the main reason for falling off has something with the quality of brazing.The influence of the thickness of the brazing layer on the mechanical properties of the picking was simulated and analyzed,and the reasonable thickness of the brazing layer is obtained.The conclusion has certain reference for the improvement of the pick's manufacturing process.
