Deutsche Bahn利用Gefertec 3DMP技术到3D打印备用铁路零件

German railway company德意志·巴恩(Deutsche Bahn)正在整合金属添加剂制造3DMPtechnology fromGEFERTEC为了提高难以生产的备件的可用性。

作为该试点项目的一部分,首次实施了3DMP流程。根据蒂娜·施林曼博士的说法,Deutsche Bahn的完整铁路系统技术高级顾问,可触发性是该公司的一个大问题。3DPM用于为较旧的机车服务车辆,包括现在过时部分。

Logistical additive manufacturing

自2016年以来, Deutsche Bahn has expressed interest in using additive manufacturing to produce spare parts for its selection of trains. This led to theMobility Goes Additive通过使用数字备件仓库使用数字铁路运输公司进行数字化物流的项目3您的软件

利用3D打印技术的许多用例之一涉及294级机车的轮子轴承盖,该车型在50年前被投入使用。盖子的原始铸件的直径为374毫米,高78毫米,重11.5千克。此外,这部分大约需要九个月才能交付,没有它,润滑剂会泄漏出方向盘,从而造成轴承的损坏。

Rolf Lenk, a German manufacturer of industrial tools and machinery, whopartnered with GEFERTEC last year,使用3D打印公司的公司帮助该部分的改进版本Arc605。该部分的设计存储在数字仓库中,也称为数字双胞胎

GEFERTEC’s 3DMP technology

As well as improving availability and significantly lowering manufacturing costs, Dr. Schlingmann noted that this approach can positively affect the environment, “Each component comes with a CO2 footprint that could be significantly reduced by additive manufacturing.”

The 3DMP process, in particular, enables rapid production of near-net shaped metal blanks using a wire as a raw material. This method is said to have an extremely high build-up rate of up to 600 cm3 per hour making it suitable for cost-effective production of larger workpieces made of steel, nickel-base, titanium or aluminum.

根据Gefertec的说法,3DMP技术有望用“近100%的物料利用”来消除废物,并节省成本为“与常规制造相比60%”。Schlingmann博士认为,这项技术与Deutsche Bahn完全一致。This is Green”环境运动。
