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.

通过其高科技策略，联邦政府的目标是越来越多的制造技术数字化以及机器，物流，工件和商品等子系统。这些现代发展通常伴随着定制材料的组合或替代，并结合新的结构概念和功能元素的整合。因此，可以使用信息和通信技术的其他传感器设计智能和/或轻量级组件。项目的目的是对潜在材料组合的科学方向研究，并确定准确的过程变量，以在墙壁上以及在双壁，深层的，深层的容器的底部产生足够的接触和压力条件。这些容器的特征是具有感官特性的集成功能元素以及用于固定系统和局部僵硬的功能元素。最后，应使用功能元素（例如螺母，加强板和组件底部的两个空白）等功能元素来开发和验证双毛坯的深度绘制方法。这两个单个毛坯的连接是通过深绘图过程进行的，其中通过选择两个毛坯的合适的薄板厚度和材料强度来实现墙壁和底部的摩擦。后来，先前或随后的激光焊接或单个毛坯的部分结构键合应提高双毛坯的连接强度。如果在形成后可以实现毛坯两个壁之间的足够水平的粘结强度和压缩比，则引入的元素将完全失去其功能。
