fig. 2 is a schematic view showing the arrangement of the connecting holes and the slits on the thin plate in an enlarged view of a portion a in fig. 1.

Detailed Description

The structure for eliminating deformation of sheet metal clinch fasteners of the present invention will be further described with reference to fig. 1 to 2.

The utility model provides a sheet metal is pressed and is riveted fastener and warp and eliminate structure, includes sheet metal 1 and sets up in 1 marginal 12 position department of sheet metal and be used for the connecting hole 11 that the pressure was riveted, characterized by: a plurality of slots 2 for releasing stress are arranged around the connecting hole 11.

As a preferred embodiment, the present embodiment is further configured such that the plurality of slits 2 are all linear slits. The linear slots 2 are distributed on the other side surfaces of the connecting hole 11, which are not corresponding to the edge 12 of the thin plate 1, so that the other side surfaces of the connecting hole 11 except the side surfaces corresponding to the edge 12 of the thin plate 1 are covered, the extrusion stress of the riveting piece on the connecting hole 11 is limited in the linear slot 2 area, and finally the extrusion stress is released through the linear slots. The diameter of the compression stress released by the attachment hole 11 towards the edge 12 of the sheet 1 is released by the edge of the sheet 1, so that no slit needs to be provided on the side of the attachment hole 11 towards the edge of the sheet 1 to ensure the structural strength between the area of the attachment hole 11 and the whole sheet 1.

As a preferred embodiment, the present embodiment is further configured such that the slit 2 is divided into a first slit 21 and a second slit 22. The first slits 21 have three and are respectively located on three sides of the connecting hole 11. That is, the first slit 21 is divided into a first slit a211, a first slit B212, and a first slit C213, the first slit a211 is located on a side of the connection hole 11 facing away from the edge 12 of the thin plate 1, and the first slit B212 and the first slit C213 are respectively located on two side surfaces adjacent to a side surface where the first slit a211 is located. In order to ensure the structural strength of the area where the connecting hole 11 is located on the thin plate 1, the three first slits 21 do not connect, i.e., a first gap 23 is formed between the first slit a211 and the first slit B212, and a second gap 24 is formed between the first slit a211 and the first slit C213.

Further, the two second slits 22 are located at the periphery of the first slits 21, and the two second slits 22 cover two gaps formed between the three first slits 21. Namely, the second slit 22 is divided into a second slit a221 and a second slit B222, the second slit a221 is located at the periphery of the first notch 23 and covers the first notch 23, and the second slit B222 is located at the periphery of the second notch 24 and covers the second notch 24, so that the connection hole 11 is covered by at least 200 degrees through the slits, and the extrusion stress generated by the clinching is limited in the slit area.

As a preferable implementation manner, this embodiment is further configured that the slit is a laser slit, and the width of the slit is 0.15 mm. The laser slotting has the characteristics of high stability and high precision, and can avoid the problem that the plate body is deformed and bent due to extrusion stress generated in the slotting process.

Based on under the above-mentioned structure, in concrete operation process, after the operation is riveted to the last pressure of connecting hole 11, the piece is riveted to the pressure passes through the slot release to the connecting hole 11 and the peripheral extrusion stress that produces of connecting hole 11, has effectively avoided extrusion stress to extend to monoblock sheet metal 1 and has leaded to monoblock sheet metal 1 to take place bending deformation's problem, promotes sheet metal 1's quality.
