Embodiment 1

[0014] Embodiment 1 see Fig. 1 and Fig. 3.

[0015] Fig. 1 is a cross-section of a floor spring door or window beam profile, the upper and lower sides of the profile are assembled into the floor spring door or the inside and outside sides of the window, both sides are in a convex-concave shape, and the other side is also in a convex-concave shape. Viewed from the whole section, it is a rectangular shape with a gap, and the profile shown in Figure 3 is put together at the gap during the assembly process to form a complete floor spring door or window beam. The beam has convex and concave shapes on three sides and has high strength.

Embodiment 2

[0016] Embodiment 2, see Fig. 2 and Fig. 4.

[0017] Fig. 2 is a cross-section of a floor spring door or a window frame profile. The upper and lower sides of the profile are assembled into the floor spring door or the inside and outside of the window, and both sides are convex and concave. Viewed from the whole section, it is a rectangle with a gap, and the profile shown in Figure 4 is put together at the gap during the assembly process to form a complete floor spring door or window frame. The two sides of the outer frame are convex and concave, with high strength, and can be directly fixed on the wall, saving channel steel and iron square pipes.

Abstract

The present invention relates to a stainless steel section material for making spring door or show-window. Said section material is characterized by that the side edge of said section material can be made into the concavo-convex form through a certain production process. Said production process includes the following steps: annealing stainless steel coiled material, spreading said coiled material, cutting, rolling and forming, surface treatment, sticking protective film on its surface and packaging.

Description

technical field [0001] The invention belongs to profile materials for doors and windows, in particular to profile materials for floor spring doors or showcases. Background technique [0002] Existing stainless steel spring door or its two sides of the profile that window is used are plane, so not only strength is low, and not attractive in appearance, and channel steel and iron square pipe need be fixed on the wall when assembling door and window, then install profile and glass. This not only wastes materials (channel steel and iron square pipe), but also increases the workload. Existing profiles for spring doors or showcases are mostly extruded from plastic steel or aluminum alloys. Due to their high melting point and poor liquid fluidity, stainless steel is not suitable for extrusion molding. At present, the profiles used for stainless steel spring doors or showcases are cut and bent by stainless steel plates through shearing machines and bending machines. This productio...
