Embodiment Construction

[0038] figure 1 A first exemplary embodiment of the apparatus 1 for making at least one bonding area in the sandwich panel 2 is shown. The sandwich panel (composite panel) 2 is composed of a middle core layer 2c and two outer cover panels 2a, 2b, and the middle core layer 2c is preferably composed of a thermoplastic material. In the present exemplary embodiment, the composite board 2 has an opening 3 that is expected to be configured to join the sandwich board with another component by using a fastening tool such as a screw or a rivet.

[0039] The apparatus 1 for making at least one joining area includes a receiving member 4 for the sandwich panel 2. In this embodiment, the receiving member 4 is provided with a positioning aid 5 for positioning the sandwich panel 2. Furthermore, the device has a tool 6 for displacing plastic material, which is preloaded with a predetermined force. The tool 6 for displacing plastic materials has a punch 8 which is mechanically preloaded by means...

Abstract

The invention relates to a method for producing a joining region of a sandwich sheet (2) having two metallic outer layers (2a, 2b) and a core layer (2c) consisting of a plastic which is arranged between the metallic outer layers, wherein the joining region is suitable for joining the sandwich sheet (2) to a further component or sheet using fastening means or a welded joint. Means (6) for displacing the plastic of the core layer (2c) from the joining region are arranged in the joining region and are prestressed for displacing the plastic, such that a predetermined force is exerted perpendicular to the surface of the joining region of the sandwich sheet. The core layer of the sandwich sheet is heated, such that, when the plastic of the core layer of the sandwich sheet is softened, the metallic outer layers (2a, 2b) of the sandwich sheet are brought into contact in the joining region by at least partial displacement of the plastic through the force of the means for displacing the plastic.

Description

Technical field [0001] The present invention relates to a method for making at least one joining area of ​​a sandwich panel having at least two metal covering layers and at least one core layer, the at least one core layer being arranged between the metal covering layers and made of plastic material, Among them, at least one joining area is adapted to join the sandwich panel to another component or plate by using a fastening tool or a welding joint. In addition, the present invention relates to a device for making at least one bonding area in a sandwich panel, and more particularly to a device for making at least one bonding area including at least one opening in a sandwich panel, the device having at least one bonding area for the sandwich panel A receptacle and a tool for removing plastic material from at least one joining area. Background technique [0002] The sandwich panel usually has two outer metal covering layers and at least one non-metallic core layer arranged between...
