A glass fiber reinforced plastic right-angle bending plate and its processing technology and special mold

Abstract

The invention discloses a glass steel right-angle bent plate and a processing technology and special mold thereof. The glass steel right-angle bent plate comprises an L-shaped plate body, two sets offixing columns are fixed to the inner wall of the L-shaped plate body, and a connection plate is movably connected between every two fixing column through a first middle shaft; the ends, away from thefixing columns, of the connection plates are provided with multiple adjacent protrusions and grooves, the protrusions of the two connection plates are matched with the grooves of the two connection plates, and the ends, close to each other, of the two connection plates are movably connected through a second middle shaft; each second middle shaft penetrates through the corresponding protrusion andthe corresponding groove, notches are formed in the ends, close to the each other, of the connection plates, and movable sleeves sleeve the portions, on the second middle shafts, in the notches. Theglass steel right-angle bent plate has the advantages that the plate assists arc plates in deformation restoration and can effectively deform and conduct corresponding action along with the arc plates, the supporting force of the arc plates is greatly increased, the service life of the arc plate is guaranteed, so that bubbles in materials in a bottom mold are greatly reduced, and accordingly the quality after formation is improved.

Description

technical field [0001] The invention relates to the technical field of FRP support, in particular to a FRP right-angle bending plate, its processing technology and a special mold. Background technique [0002] Fiberglass reinforced plastic (FRP) is also called GFRP, that is, fiber reinforced plastics, which generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics made of glass fiber or its products are called glass fiber reinforced plastics, or glass fiber reinforced plastics, which are different from tempered glass. Due to the different types of resins used, there are polyester FRP, epoxy FRP, and phenolic FRP. Light and hard, non-conductive, stable performance, high mechanical strength, less recycling, corrosion resistance. It can replace steel to manufacture machine parts, automobiles, ship shells, etc. The scientific name of FRP is fiber reinforced plastic, commonly known as FRP (Fiber Reinforced Plas...

AI Technical Summary

Problems solved by technology

[0003] The FRP right-angle bent plate is not only cheap, but also easy to use and light. Most of the existing FRP right-angle bent plates are provided with reinforcing ribs on an L-shaped plate. Although the support strength of the L-shaped plate can be increased, for some curved plates For example (such as septic tanks and other large utensils assembled by curved plates), since the curved plates are prone to deformation when receiving gravity, if an L-shaped plate with ribs is used at this time, it will easily lead to The arc-shaped plate produces a bulge at the place where it contacts the L-shaped plate (5 as shown in the attached drawing of the specification figure 1 Shown), severe cases will cause cracks in the curved plate, which will reduce the service life of the curved plate
