金刚石圆锯片基体辊压预应力处理工艺参数试验研究
|
摘要
对典型Φ1650 mm金刚石圆锯片进行预应力处理,采集预应力处理前后锯片基体的轴向变形量,研究预应力施加位置与载荷对适张状态的影响。试验结果表明:预应力施加位置离圆心越远,切向拉应力的效果越明显,锯片的轴向刚性与稳定性增强,锯切过程中锯片基体抑制轴向受载变形的能力提高216%～232%;预应力施加载荷使圆锯片抑制变形的能力提高,若预应力施加载荷过大,预应力处理后锯片整体刚性与稳定性变弱,基体抑制轴向受载变形能力仅提高155%～187%。
Typical Φ1 650 mm diamond circular saw blade was pretreated by prestressing. The axial deformation of saw blade substrate before and after prestressing treatment was collected to study the effect of prestressing position and load on tensile state. The test results showed that the position of prestress was positively related to the radial distance, and the effect of tangential tensile stress was more obvious. The axial rigidity and stability of saw blades was enhanced, and the ability of saw blade steel core to restrain the axial load-bearing deformation was enhanced by 216%～232%. The prestressing load increased the ability of the circular saw blade to suppress deformation. If the prestressing load was too large, the overall rigidity and stability of the saw blade after the prestressing treatment weakened, and the ability of the matrix to suppress the axial load deformation only increased by 155%～187%.
