简介:摘要:近年来,我国工业建设发展非常迅速,推动我国整体经济建设的快速发展。床身是机床支撑的重要大型部件,起着承上启下的作用,对上承载着机床的各个功能部件,对下采用螺栓与地基固定连接。过去的床身设计主要采用类比法和经验法,没有科学理论数据作支撑,只有通过负重试验、负荷切削试验及精度检验等,间接地反映床身地脚螺栓连接部分的刚性。

简介:摘要:3D打印技术作为快速成型技术,将数字模型文件为基础,采用粉末状金属或塑料等可黏性材料,通过逐层打印文件的方式来构造物体。3D打印技术目前常用于模型制造、工业设计等领域中,目前也用于一些产品的直接制造,也采用该技术打印零部件。3D打印技术在珠宝、工业设计、建筑、汽车、牙科、土木工程、航空航天等领域广泛应用。3D打印技术被认定为促进第四次工业革命发展的很重要技术,常规统一生产的产品复杂性、成本以及可行性都达到极限的情况下,3D打印技术则发挥着重要的作用。本文针对3D打印技术的发展以及特点进行分析,分析3D打印砂型技术在铸件开发中的应用效果,通过研究发现,采用3D打印砂型技术提高了复杂铸件开发的效率,有效节省了铸造的成本。
