Benefits of technology

This patent describes a way to make composite sheet metal parts with a metal edge region. By heating the selected edge region and controlling the positioning, heating, force application, and joining process using a multi-axis arm robot or handling system, the production of these parts can become highly automated.

Problems solved by technology

The joining methods commonly used with sheets, such as fusion welding and soldering, cause problems, however, on account of their high energy input.
With the high energy input, the composite sheet metal part may be damaged due to the fact that the non-metallic layer or plastic layer arranged between the covering sheets is damaged by the heat input, and as a result a sufficiently good connection between a composite sheet metal part and a metal part can be achieved only with difficulty.
This method is, however, very complicated and can be automated only with difficulty.

Embodiment Construction

[0041]A first embodiment of the method according to the invention is first of all illustrated in FIG. 1 in which a composite sheet metal part 1 consisting of two outer covering sheets 2, 3 and a plastic layer 4 arranged between the covering sheets 2, 3, is heated in its edge region 5 in such a way that the plastic layer 4 in this edge region 5 softens. The heating of the edge region 5 can take place in various ways and means. In the present exemplary embodiment a current is fed to the composite sheet metal part 1 via the roller 6 and the current conducting clamp 7 and via the dolly bar 8, wherein especially in the contact region of the roller 6, namely in the edge region 5, a powerful heating of the upper and optionally of the lower covering sheet 2, 3 takes place so that the plastic layer 4 provided in the edge region 5 appreciably softens. As a result of the force transmitted to the roller 6 in the direction of the composite sheet metal part 1 the upper covering sheet 2 in the edg...

Abstract

The invention relates to a method for producing a composite sheet metal part with a metal edge region comprising two outer covering sheets of metal and at least one layer consisting of a plastic arranged between the covering sheets. The method is characterised in that a selected edge region of the composite sheet metal part is heated in such a way that the plastic layer arranged between the outer covering sheets softens, by applying a force to at least one outer covering sheet in the edge region the covering sheets are pressed against one another at some points or regions, so that the plastic layer in the edge region subjected to the force is expelled, and subsequently or at the same time as the application of the force both covering sheets in the compressed edge region are joined to one another at least over some regions or points.

Description

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS[0001]This patent application is a continuation of PCT / EP2012 / 070041, filed Oct. 10, 2012, which claims priority to German Application No. 102011054362.7, filed Oct. 10, 2011, the entire teachings and disclosure of which are incorporated herein by reference thereto.FIELD OF THE INVENTION[0002]The invention relates to a method for producing a composite sheet metal part with a metal edge region, which comprises two outer covering sheets of metal and at least one layer consisting of a plastic arranged between the covering sheets. In addition, the invention relates to a device for carrying out the method according to the invention.BACKGROUND OF THE INVENTION[0003]Composite sheet metal parts are often used in the form of a sandwich sheet, which comprises two outer covering sheets and a non-metallic sheet, normally consisting of a plastic that is arranged between the covering sheets. One reason for the increasing use of composite sheet metal p...
