钎焊金刚石锯片加工HRB400钢的模型及试验分析

Model and Experimental Analysis of Monolayer Brazed Diamond Saw Cutting Rebar HRB400

尝试以HRB400螺纹钢的切屑厚度为切入点,对单层钎焊金刚石锯片锯切性能进行研究。建立锯片切割螺纹钢理论模型,通过计算得单颗金刚石最大锯切厚度值。通过试验得到的切屑类型有剪切屑及少量熔球屑,对剪切屑厚度值进行测量并与切屑厚度理论计算值进行比较,发现两者之间的数值吻合很好。经过分析得到螺纹钢锯切加工模型,探讨金钢石锯片加工钢铁材料时的锯切机理。

Chip thickness of rebar HRB400 is used as a starting point to study the mechanism of sawing. It is anastomotic greatly between theoretical single diamond maximum cutting thickness and measured values of chip thickness. This paper analyszes the processing model of sawing screw-thread steel and obtains the cutting mechinism of sawing steel materials withe the diamond saw.
