Problems solved by technology

The disadvantage here, however, is that gap formations still occur, which are only smaller compared to methods without pilot holes
In addition, additional method steps are required for producing the pilot holes, which are time-consuming and expensive, since for this purpose a generally unnecessary machine must be provided and the engaging elements must be positioned in this machine

Embodiment Construction

[0031] figure 1 A first step of the manufacturing method is shown. A first joining element 10 is shown, onto which adhesive 30 has been applied. The adhesive 30 is provided on the joint face 11 of the first joint element. The second joining element 20 configured as a plate has a cup-shaped profile 24 produced in a press shop by a deep-drawing process. This cup-shaped profile projects from the plane of the second joining element 20 pointing away from the first joining element 10 and defines a recess 23 on the joining face 21 of the second joining element 20 facing the first joining element 10 . The flow-forming screw 40 is arranged in the screw position P centrally above the cup-shaped profile 24 .

[0032] The recess 23 has a diameter X measured on the joint face 21 of the second joint element 20 . Furthermore, the recess 23 has a depth Z measured from the joint face 21 of the second joint element 20 to the deepest point of the recess.

Abstract

The invention relates to a method for producing a composite component from a first joining element (10) and a second joining element (20) by means of an adhesive (30) and a flow drill screw (40), in which, before attaching the second joining element (20) to the first joining element (10), a recess (23) is made around the at least one screw position (P) in which the respective flow drill screw (40)penetrates the second joining element (20), in a joining surface (21) of the second joining element.

Description

technical field [0001] The invention relates to a method for producing a composite component from a first joining element and a second joining element by means of an adhesive and at least one flow forming screw (or flow drilling screw). Background technique [0002] In the prior art, methods are known for producing composite components from two joining elements by means of adhesives and flow-forming screws. With this method, usually two flat plates or one flat plate is connected to another component as a joining element. The plates or the connection of the plates to the component should be made as loadable as possible by means of adhesive and flow-formed screws. When the or this plate is connected to the component by means of a flow-forming screw, the flow-forming screw penetrates at least one of the joint elements involved and forms the hole and the thread there. When forming holes and threads, material is melted and displaced. In the known method, the displaced material...
