Problems solved by technology

[0005] However, because the middle plate itself is a metal material with high technical requirements for flatness, especially steel plates, and requires high technical precision for the formed entire sandwich structure metal plate, the protective panel cannot be easily and firmly fixed on the middle plate
In addition, the protective panel used for the metal sheet of the sandwich structure can only be a thin metal sheet, or even an ultra-thin metal sheet. No matter which reliable connection and fixing method is adopted, it will affect the entire sandwich structure formed. Variations in the flatness of the surface of the sheet metal, thereby failing to meet the high precision required for industrial equipment or industrial system design
This increases the difficulty of developing high-precision sandwich metal sheets with protective panels

Embodiment 1

[0041] see figure 1 and figure 2 As shown, the sandwich metal sheet of the present invention has a sheet body 1 . The plate body 1 is a rectangular structure with a length of about 300mm, a width of about 80mm, and a thickness of about 6-7mm. Panel 13 is composed.

[0042] Wherein, the middle plate 12 is a steel plate with a thickness of about 5 mm. The thickness of the middle plate 12 is greater than the thickness of the first panel 11 and the second panel 13 respectively. The two surfaces of the middle plate 12 are required to be flat and smooth respectively.

[0043] The thickness of the first panel 11 and the second panel 13 are equal, and their thicknesses are about 0.6mm respectively. The surface area of ​​the first panel 11 and the second panel 13 substantially matches the surface area of ​​the middle panel 12 . The first panel 11 and the second panel 13 are an integral structure, and they are bent into a U shape on one long side relative to the middle plate 12. ...

Embodiment 2

[0076] The sandwich metal sheet of the invention has a sheet body. The plate body is a rectangular structure with a length of about 300mm, a width of about 80mm, and a thickness of about 6-7mm. It is mainly composed of a first panel, a middle panel and a second panel that are sequentially riveted together by a plurality of rivets.

[0077] Wherein, the middle plate is a steel plate with a thickness of about 5mm. The thickness of the middle plate is respectively greater than the thickness of the first panel and the second panel. The two surfaces of the middle plate are required to be flat and smooth respectively.

[0078] The thickness of the first panel and the second panel are equal, and their thicknesses are about 0.8mm respectively. The panel areas of the first panel and the second panel substantially match the panel area of ​​the middle panel. The two surfaces of the first panel and the second panel are required to be flat and smooth respectively, and the flatness of th...

Embodiment 3

[0096] The sandwich metal sheet of the invention has a sheet body. The plate body is a square structure with a side length of about 200mm and a thickness of about 7-8mm. It is mainly composed of a first panel, a middle panel and a second panel which are sequentially riveted together by a plurality of rivets.

[0097] Wherein, the middle plate is a steel plate with a thickness of about 6mm. The thickness of the middle plate is respectively greater than the thickness of the first panel and the second panel. The two surfaces of the middle plate are required to be flat and smooth respectively.

[0098] The thickness of the first panel and the second panel are equal, and their thicknesses are about 0.7mm respectively. The panel areas of the first panel and the second panel substantially match the panel area of ​​the middle panel. The two surfaces of the first panel and the second panel are required to be flat and smooth, and the flatness of the outer surfaces of the first panel ...

Abstract

The invention discloses a sandwich metal plate and a riveting forming method thereof. The sandwich metal sheet has a sheet body, and the sheet body is mainly composed of a first panel, a middle panel and a second panel riveted together by rivets in sequence, the middle panel is a steel plate, and the thickness of the middle panel is respectively greater than that of the first panel. A panel and a second panel, the thicknesses of the first panel and the second panel are respectively ≤0.8mm, the ends of the rivets are flush with the surfaces of the corresponding first panel and the second panel, and the first panel and the flatness of the surface of the second panel are respectively ≤0.4mm. The invention enables the middle plate-steel plate to be covered by panels on both sides, and the panels on both sides are firmly and reliably formed on the corresponding surfaces of the middle plate with high flatness, which not only meets the technical requirements for high-precision use of industrial equipment or industrial systems , and effectively ensure that the middle plate can serve for a long time, with good reliability and strong practicability.

Description

technical field [0001] The invention relates to a metal sheet, especially a metal sheet with high flatness technical requirements, specifically a sandwich metal sheet, and a riveting forming method for the metal sheet. Background technique [0002] In the design of industrial equipment or industrial systems, in order to achieve high-safety structural molding and / or realize control functions, metal plates, especially steel plates (such as control panels or door panels, etc.), are usually involved, and the required The structural precision of the metal sheet is very high, and a key point of this high-precision technical requirement is flatness. [0003] At present, the metal plates used in industrial equipment or industrial systems, especially steel plates (for the convenience of distinction, hereinafter referred to as structural plates), are usually bare plate structures, that is, the structural plates used are only a layer of high flatness without protection. structure. In...
