Example Embodiment

[0030] Example: see Figure 1-Figure 6 , the present embodiment provides an integral molding process for a profiled material, which includes the following steps.

[0031] (1) Cutting: The cutting process is performed on the raw material according to the required length to obtain a strip-shaped profiled material 1 of corresponding length. The strip-shaped profiled material 1 has at least one horizontal portion 11 and at least one The vertical portion 12 is connected to the horizontal portion 11 and is perpendicular to the vertical portion 12 .

[0032] (2) Punching of small openings: For the position to be bent, a forming small opening 2 is punched on the vertical part 12 to facilitate the bending and forming of the strip-shaped profiled material 1 , and a small forming opening 2 is reserved between the forming small opening 2 and the horizontal part 11 . There is a certain distance d to form a reinforcing connection part; the reserved distance d is preferably 1 / 3 to 1 / 4 of th...

Abstract

The invention discloses an integral molding process for a profile. The integral molding process for the profile comprises the steps of 1) cutting: cutting a raw material according to needed length; 2) small hole punching: punching a small molding hole which can facilitate strip-shaped profile bending at a position which is required to be bent; 3) bending; 4) large hole finish cutting. The integral molding process for the profile disclosed by the invention has the advantages that the process is simple, the efficiency is high and metallic frames with high structural stability can be quickly manufactured; since the vertical parts of the strip-shaped profile are not fully cut off when the small molding hole is punched but certain distance is reserved to form a reinforcing connecting part, after the profile is bent, the vertical parts on the two sides of the small molding hole can be connected to form an integrated connecting structure without using a welding process or other connecting parts, the overall structural strength is effectively increased, the stability is good, the appearance is attractive, the welding process is not used, and not only can the production process of the traditional metallic frames be effectively simplified and can the production efficiency be improved, but also the saving of energy and production raw materials can be facilitated and the production cost is decreased.

Description

technical field [0001] The invention relates to the bending and forming technology of special-shaped materials, in particular to an integrated forming process of special-shaped materials. Background technique [0002] Metal frames are currently widely used in various products, such as displays in electronic products. Its structure is usually combined into a metal frame by four long workpieces. [0003] The existing metal frame manufacturing process pre-cuts a V-shaped notch at the corner of the strip-shaped metal material. The cross-sectional shape of the strip-shaped metal material is usually L-shaped, that is, the strip-shaped metal material includes horizontal parts and vertical parts. The straight part, the V-shaped notch has basically cut off the vertical part, and then bends and shapes it through the V-shaped notch to form a metal frame. The structural stability of such a metal frame is not high because the vertical parts have been cut off and there are no connecting...
