Method and Device for Producing a Composite Sheet-Metal Part with a Metal Edge Region

摘要

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.

1. 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 arranged between the covering sheets consisting of a plastic, the method comprising the steps of:
heating a selected edge region of the composite sheet metal part in such a way that the plastic layer arranged between the outer covering sheets softens, applying a force to at least one outer covering sheet in the edge region such that the covering sheets are pressed against one another at some points or regions so that the plastic layer in the edge region subjected to a force is expelled, and joining, subsequently or at the same time as the application of the force, both covering sheets in the compressed edge region to one another at least over some regions or points.
