轮胎挤出口型参数化设计与加工

Parameterized Design and Processing of Extrusion Die for Tire

以11R22.5轮胎挤出胎面为例,介绍采用三维软件CATIA进行挤出口型参数化设计的方法。根据客户提供的挤出部件尺寸及胶料膨胀系数,利用EXCEL和CATIA软件实现口型型腔的参数化设计,并将口型设计文件导入数控软件,进行机床加工,实现挤出口型准确、快速设计与加工。

Taking the extruded tread of 11R22.5 tire as an example,the method of parameterized design of extrusion die using three-dimensional software CATIA was introduced.According to the extrusion part size and rubber expansion coefficient provided by the customer,the parameterized design of the die cavity was obtained by using EXCEL and CATIA software,and the die design file could be imported into the numerical control software for machine processing.With the parameterized method,accurate and rapid design and processing of the extrusion die were achieved.
