Description

Technical Field

[0001] This utility model relates to the technical field of building profiles, and in particular to a roll forming equipment. Background Technology

[0002] Current profiles and panels (especially flooring and wall panels) use aluminum alloy integral molding as the base material. The cross-section of the base material has multiple cavities, and there are reinforcing ribs between adjacent cavities. The reinforcing ribs connect the top and bottom plates of the base material, and the surface of the base material is covered with a polymer material surface layer.

[0003] Aluminum profiles are typically produced using an extrusion molding process, which has several drawbacks: it requires the manufacture of high-precision molds, resulting in high mold costs; it demands that the aluminum alloy material possess sufficient plasticity and deformation capacity, placing high demands on material properties; and because defects and stress may occur during the extrusion process, subsequent straightening and trimming are necessary, leading to a certain scrap rate.

[0004] In addition, aluminum alloys themselves are expensive. To reduce costs, a lower-cost base material and equipment that can efficiently manufacture profiles and sheets using that base material are needed. Utility Model Content

[0068] Unlike Example 1, this example uses only one strip steel conveyor line. Correspondingly, the substrate roll forming line 100 also uses only one line, producing only the base plate 402 of the profile sheet 400 (see Example 1). Figure 10The base plate 402 produced in this embodiment differs from the base plate 402 in Embodiment 1. The difference is that the base plate 402 in this embodiment does not have the installation position of the cover plate 401 in Embodiment 1, nor does it have the cavity directly below the cover plate 401. After one side of the strip is bent towards the center, it directly joins the bent part on the other side and is welded into shape by the composite connecting device 300.
