项目摘要

With its high-tech strategy, the federal government is aiming for an increasing digitalization of manufacturing technologies and the subsystems such as machines, logistics, workpieces, and commodities. These modern developments are often accompanied by a combination or substitution of customized materials in combination with new structural concepts and the integration of functional elements. Therefore, intelligent and/or lightweight components can be designed with additional sensors of the information and communication technology.The objective of the project is the scientifically oriented investigation of potential material combinations and the determination of accurate process variables to generate sufficient contact and pressure conditions in the wall and at the bottom of double-walled, deep-drawn containers. These containers are characterized by integrated functional elements with sensory properties as well as functional elements for fastening systems and for local stiffening. Finally, a method for deep drawing of double blanks shall be developed and validated using functional elements such as nuts, stiffening plates, and sensory components between the two blanks at the bottom of the components. The joining of these two single blanks is performed through the deep drawing process, in which the friction in the wall and at the bottom is achieved by choosing a suitable sheet thickness and material strength of both blanks. Later on, a previous or subsequent laser welding or partial structural bonding of individual blanks should increase the joining strength of the double blanks. If no sufficient levels of bonding strength and compression ratios between the two walls of the blanks can be achieved after forming, the introduced elements will entirely lose their function.

通过其高科技战略，联邦政府的目标是提高制造技术和子系统（如机器、物流、工件和商品）的数字化。这些现代发展往往伴随着定制材料的组合或替代，结合新的结构概念和功能元素的整合。因此，智能和/或轻量级组件可以设计与附加的传感器的信息和通信技术。该项目的目标是科学地研究潜在的材料组合，并确定准确的工艺变量，以在双壁深拉容器的壁和底部产生足够的接触和压力条件。这些容器的特点是具有感官特性的集成功能元件以及用于紧固系统和局部加强的功能元件。最后，利用元件底部两个坯料之间的螺母、加强板和感觉元件等功能元件，开发和验证双坯料深拉深的方法。这两个单坯料的连接是通过拉深工艺进行的，在拉深工艺中，通过选择合适的板材厚度和两种坯料的材料强度来实现壁和底部的摩擦。随后，对单个坯料进行先前或随后的激光焊接或局部结构粘合，应提高双坯料的连接强度。如果成形后坯料两壁之间不能达到足够的结合强度和压缩比，则引入的元件将完全失去其功能。
