Technical Field

Background

With the development of industrialization, the concept of the frame cabinet is first proposed by the early-started foreign companies. One of them is the Lital Shuanghe Germany. The earlier product used a nine-fold profile, followed by a sixteen-fold profile. At this stage, it is generally accepted in the industry that by increasing the number of folds, more cold work hardening effect is achieved, increasing the strength of the cabinet.

Patent No. 201010506024.6 discloses a twelve-fold profile with cold-pressed corrugations, which improves the bending strength by 30% of a twelve-fold profile compatible with the sixteen-fold profile of latarville bijour by changing the cross-sectional shape of the profile. While maintaining and enhancing the cold-work hardening effect, the patent also discloses a method of making cold-pressed wrinkles.

For projecting convenience and ease of use, patent application No. 201680065240.7 discloses a new technique for frame profiles for switchgear cabinets racks and the corresponding racks. It has two U-shaped hollow connecting pieces which serve to connect and support the inner profile side and the outer connecting side. The water guide plate is also provided with an obtuse-angle groove, so that the water guide effect is achieved. However, the new frame profile has only 9 folded edges, the effect of cold hardening is less, and the strength of the profile is reduced. Meanwhile, the hollow U-shaped bending processing technology is complex, the single-layer connecting side face cannot be directly tapped, and a rivet nut needs to be manufactured, so that the cost is high.
