Problems solved by technology

[0003] During the riveting process, the axial pressure on the fastener also acts on the plate at the same time. Due to the small thickness of the plate, indentations will be produced on the side away from the fastener, which will affect the appearance quality and the mechanical properties of the riveted structure. Highly demanding products, the indentation will cause the riveted structure to become a defective product
The way of glue bonding can solve the problem of board indentation, but the glue will pollute the environment, and the structure bonded by glue has poor weather resistance. When the temperature exceeds 80°C, the mechanical properties of the structure drop significantly

Embodiment Construction

[0053] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] The inventors of the present application found that the reason why the existing method of riveting fasteners on plastic plates such as metal plates will cause defects such as indentations or burrs on the plate Excessive force is applied to the riveted plate, which causes undesired deformation of the sheet at the riveted joint.

[0055] The inventors found that if a wall portion between two concave regions is pre-formed on a pla...

Abstract

The invention discloses a riveting method and a riveting structure, and the riveting method comprises the steps: providing a plate which is provided with a first side and a second side opposite to the first side; a wall part is formed on the first side of the plate, and the two sides of the wall part are provided with concave areas; placing a fastener into the recessed area, and enabling the fastener to be adjacent to one side of the wall part; and acting force is applied to the wall part from the other side, not adjacent to the fastener, of the wall part, so that the wall part is deformed to at least partially wrap the fastener. According to the scheme, indentations can be prevented from being generated on the back surface of the plate.

Description

technical field [0001] The invention relates to the technical field of riveting, in particular to a riveting method and a riveting structure. Background technique [0002] There are many ways to install components such as fasteners on the board. Commonly used methods include pressure riveting and glue bonding. [0003] During the riveting process, the axial pressure on the fastener also acts on the plate. Due to the small thickness of the plate, an indentation will occur on the side away from the fastener. For demanding products, this indentation can lead to defective riveted structures. The method of glue bonding can solve the problem of indentation of the board. However, the glue will pollute the environment, and the structure bonded by glue has poor weather resistance. When the temperature exceeds 80 °C, the mechanical properties of the structure will be greatly reduced. SUMMARY OF THE INVENTION [0004] In order to overcome the defects in the prior art, the present i...
