摘要:

利用流体力学理论,针对基于微流挤压成形的陶瓷浆料挤出过程的关键部件挤压凹模的流道形状进行了设计,使用ANSYS软件对挤压凹模出口横截面的流速和流道内部压力场的分布情况进行模拟,分析了四种不同流道形状挤压凹模内部压力场和出口流速的分布规律。研究结果为解决陶瓷浆料挤压成形工艺的难点问题提供了理论依据,具有重要的参考价值。

Abstract:

According to the  theory of fluid mechanics,the flow shape of extrusion cavity die  was designed,which  was key part  of ceramic slurry microflow extrusion forming process.Using   ANSYS  software,the flow velocity of extrusion cavity die export cross section and the distribution of pressure within the flow field  were  simulated.The internal pressure field and outlet flow velocity distribution of four different flow shape extrusion cavity dies were  analyzed.The research  provides  the theoretical basis to solve the difficult problem of ceramic paste extrusion forming process and has a important reference value.

Key words: ceramic slurry;extrusion forming;extrusion cavity die, simulation
