Description
Technical field
The present invention relates to building material field, particularly a kind of metal lagging and production method.
Background technology
At present, metal lagging is widely used in the decoration of exterior wall field of building.Metal lagging is simple and light,
Picture on surface can be customized as needed, while top layer good corrosion resistance.
Existing metal lagging needs punching press to fall each corner in process of production, is made with the bending of the rear wall for facilitating
Industry, but punch-out edge is not coated with surface corrosion-resistant erosion resisting coating and be partially exposed at outward, easily it is subject in use
Corrosion, influences the using effect and bulk strength of bulk metal decorative panel.
Because in consideration of it, special propose this invention.
The content of the invention
It is an object of the invention to provide a kind of metal lagging and production method, metal lagging can be effectively avoided
Corrosion of the edge portions caused by punching press.
A kind of metal lagging, including panel and side wall, the side wall are to the same side bending from the edge of metallic plate
Into, a bending structure is configured between adjacent wall, the bending structure is surrounded by side wall crease extended line with metallic plate edge
The clipped backward metal lagging inner side bending in part is formed.
Preferably, the side of the metallic plate scribbles corrosion-resistant finishes, and side wall bends to the side without corrosion-resistant finishes.
Preferably, the metallic plate edge surrounds part and is washed out from internal vertex with the side wall crease extended line
A part is sheared to form breach.
Preferably, the bending structure fits in the inner wall through bending.
Preferably, it is provided with a thermal insulation packing layer in the metal lagging.
Preferably, the thermal insulation packing layer is rock wool heat-preservation packed layer or polyphenylene granule heat-insulating packed layer.
Preferably, the side of the metal lagging is provided with the hole for installation connecting element.
A kind of production method of metal lagging, follows the steps below successively：
(1) corrosion-resistant finishes is sprayed on a metal plate；
(2) metallic plate is processed；
(3) side wall crease extended line and metallic plate edge are surrounded after part is sheared and bends side wall, by side wall folding
Trace extended line surrounds part and is bent to form bending structure along side wall crease extended line with metallic plate edge；And
(4) flat metal plates edge.
A kind of metal lagging and production method that the present invention is provided, the method will bend after the corner cutting of metallic plate
The inner side of metallic plate, so, it is to avoid the edge of metallic plate is exposed to outside, and then avoids caused by four angles of metallic plate are fallen in punching press
Metal lagging edge do not have corrosion-resistant protective layer easily corrosion problem.

Specific embodiment
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Embodiment one
Refer to Fig. 1-3, it is the sheet material of 0.2-2mm that metal lagging uses thickness, material include but is not limited to PCM plates,
Stainless steel plate and precoating plate.The overall processing flow of metal lagging includes metallic plate pretreatment, bending side wall, treatment bending
The steps such as structure, smooth edge and later stage treatment.
In the preprocessing process of metallic plate, by corrosion-resistant finishes on the side even spread of metallic plate, then according to institute
The width of the decorative panel side wall 2 for needing is bent, and the direction that side wall 2 bends is not coated with being furnished with the one of corrosion-resistant finishes for metallic plate
Side.The folding line area defined of side wall 2 is panel 1.The folding line extended line of side wall 2 and metallic plate edge are surrounded in process
Diagonally cut open (as shown in Figure 2) since inside fixed point 5 in region.The purpose of cutting be in order to during bending (under
Text narration), corner is easier to fold into metallic plate inner side.Although if do not cut to bend, corner is right
Bending deformation at linea angulata needs larger external force effect, improves difficulty of processing.
In the step of bending side wall, the folding line extended line of side wall 2 is surrounded with the edge of metallic plate in the corner of metallic plate
Region bends inwards along the folding line extended line of side wall 2, forms bending structure 3 as shown in Figure 3.
Bending structure is processed afterwards, bending structure 3 is repaired, bending is attached at the inner side of inwall 2.
Behind the edge of flat metal plates, one can be entered according to the practical service environment of metal lagging and use demand
Step carries out the processing in later stage, and these processing include：
As needed, thermal insulation packing layer can be filled in metal finishing intralamellar part, thermal insulation packing layer can be rock wool heat-preservation
Packed layer or polyphenylene granule heat-insulating packed layer.
As needed, several connector mounting holes 4 can be on the side wall 2 constructed, such as corner brace is installed in order to after
Deng connector.The shape of mounting hole 4 can have various, and circular hole form is used in the present embodiment.
As needed, can be printed on panel 1 and draw out decorative pattern and pattern, such as wood grain, marble grain, to reach more
Good decorative effect.
Embodiment two
Fig. 4 is refer to, the corner of metallic plate has been fallen in metallic plate stamped punching press since internal vertex before bending, remaining
With embodiment one.
Embodiment three
Fig. 5 is refer to, metallic plate is stamped before bending to be cut open since internal vertex to corner edge, remaining is with real
Apply example one.
Metal lagging provided by the present invention is described in detail above.Specific case used herein is to this
The principle and implementation method of invention are set forth, and the explanation of above example is only intended to help and understands that core of the invention is thought
Think.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, may be used also
Some improvement and modification are carried out with to the present invention, these are improved and modification is also fallen into the protection domain of the claims in the present invention.
