【摘要】 渐开线花键冷搓成形工艺是一种精密塑性成形加工工艺。为探索齿条形刀具的角度的变化对渐开线花键成形结果的影响,采用ANSYS软件,基于北方易初和洛阳工学院合作已经研制成功的搓挤摩托车曲柄渐开线花键的齿条形刀具,变更刀具齿形角分别进行成形过程仿真并进行结果分析比较;刀具齿数多,形状复杂且整个研究过程将需要多次进行刀具建模,若在ANSYS中建模则非常费时费力,故选择AutoCADVBA编程实现刀具的参数化绘图造型而后导入ANSYS的方法。每运行一次AutoCADVBA宏程序,即可方便快捷地得到一把不同的虚拟刀具,大大提高整个研究进程的效率,同时也为类似问题的研究提供了一种有效的参考途径。更多还原

【Abstract】 The cold rolling process for involute spline manufacture is a new precise forming process.The simulation of the forming process is very valuable.The modeling of rack-kind tools is very difficult in ansys.To rise work efficiency , AutoCAD VBA method is used to establish the geometric model. ANSYS can import the geometric model by means of software interface. All of above give the references for engineering and study application for similar projects.更多还原
