Sheet-metal composite, method for joining sheets and joining device

摘要

A metal sheet composite comprising an outer metal sheet having a flange which is folded over around a flanging edge; an inner metal sheet which forms a joint with the flange; and a welding or soldering seam which is produced on or in the joint and fixedly connects the metal sheets to each other. A method for joining metal sheets and a device for flanging and welding or soldering are also disclosed. The device includes: a tool head; a flanging member, arranged on the tool head, for roll-flanging or slide-flanging; and a welding or soldering tool arranged on the tool head, wherein the flanging member and the welding or soldering tool are arranged such that the flanging member forms a pressing means for a welding or soldering process which can be performed using the welding or soldering tool.

1. An arrangement comprising:
a first metal sheet having an L-, U- or V-shaped flange which is folded over, a second metal sheet which overlaps said flange on the inside or the outside or faces an end or a face side of said flange to form a joint with said flange, a flanging and welding or soldering tool with
a tool head,a connector for connecting the tool head to an actuator,a flanging member, arranged on the tool head, for roll-flanging or slide-flanging,a welding or soldering tool arranged on the tool head, and wherein the flanging member folds the flange of the first metal sheet into a position or orientation required for welding or soldering, and the welding or soldering tool produces a seam near to the position where the flanging member is in contact with the flange, and wherein the flanging member during folding the flange in said position presses on the first metal sheet and/or on the second metal sheet for the flanging process, and at the same time said flanging member presses the first and second metal sheet against each other for the welding or soldering process so that the second metal sheet for the welding or soldering process abuts the inside, the outside or the face side of a free end of the flange and the welding or soldering tool connects the second metal sheet directly to said inside or said outside or said face side of said free end of the flange of the first metal sheet.
