Embodiment Construction

[0029] In the various figures, identical components are always provided with the same reference numerals and are therefore generally referred to or mentioned only once in each case.

[0030] exist figure 1 In , the method provided by the invention for punching openings 8 in lightweight metal sheets 2 is presented. The lightweight metal sheet 2 preferably comprises at least two metallic outer layers 31 between which at least one non-metallic core layer 32 is arranged. Despite its light weight, the lightweight metal sheet 2 has high local rigidity and provides effective sound damping. Many applications require that these lightweight metal sheets 2 can be joined to other sheet metal parts or components. However, joining methods commonly used for metal sheets, such as welding or brazing, create problems due to their high heat input. The reason for this is that a thermoplastic material is preferred as plastic for the core layer, which has the effect that the core layer 32 made o...

Abstract

The present invention proposes a device, robot with such a device, punch for such a device and method for punching an opening into a lightweight metal sheet that has at least two metallic outer layers and at least one non-metallic core layer arranged between the metallic outer layers, the device having means for carrying out a relative movement of a punch with respect to the lightweight metal sheet and a quill with an integrated heat source, the punch being able to be heated up by the heat source.

Description

technical field [0001] The invention relates to a device, a robot with the device, a punch for the device and a method for punching openings in lightweight metal sheets. Background technique [0002] Lightweight metal sheets are known in the prior art and preferably comprise at least two metallic outer layers between which at least one non-metallic core layer is arranged. Despite its low weight, the lightweight metal sheet has high local stiffness and is able to provide effective acoustic damping. Many applications require that these lightweight metal sheets can be joined to other sheet metal parts or assemblies. However, joining methods commonly used for metal sheets, such as welding or brazing, can be problematic due to their high heat input. The reason for this is that thermoplastic materials are preferably used as the plastic core, which has the effect that cores made of such plastics would melt or be damaged in some other way during the bonding process. [0003] Ther...
