基于3D打印技术的重卡自动变速器壳体铸件的快速开发

Rapid Development of Automatic Transmission Housing for Heavy Trucks by 3D Printing Technology

以重卡自动变速箱壳体铸件为实例,通过MAGMA铸造模拟软件、3D砂型打印、组芯以及砂型重力铸造技术等手段,实现了重卡自动变速箱壳体铸件的快速开发,最终确定了3D打印砂型+组芯+重力浇注的新工艺。

Taking heavy truck automatic transmission as an example,which has realized the rapid development of heavy truck automatic transmission through casting simulation software named MAGMA,3D printing of sand mold and core,and sand gravity casting technology.Finally,a new process of 3D-printed sand mold,core and gravity casting was established.
