Detailed Description

The invention will be described in further detail below with reference to the drawings and specific examples.

As shown in fig. 1: a preparation process of a middle mullion of a window frame comprises the following steps:

s101: a thin metal plate is taken.

Specifically, the sheet metal plate 1 of the present embodiment is preferably a galvanized sheet iron, and the galvanized sheet iron is a galvanized sheet iron, because the electrode potential of zinc is lower than that of iron, and the chemical property is relatively active, a zinc oxide film can be quickly generated in the air, the zinc oxide film is very dense, so that the zinc and the steel plate inside are protected from corrosion, even if the galvanized layer is scratched, the zinc is oxidized first to protect the iron, and thus the corrosion resistance of the steel plate is greatly improved. Therefore, the tinplate has the advantages of excellent corrosion resistance and difficult rusting. The white iron sheet can resist the high temperature of more than 400 ℃, has better strength than aluminum alloy, good ductility, convenient processing and preparation and low cost. The thin metal plate has certain width and length, and the width of the thin metal plate is required to be capable of pressing a hollow cuboid structure with a wrench edge.

S102: one side of the thin metal plate 1 is pressed out of the top surface 11 and two side surfaces 12 of the hollow cuboid, the bottom surface 13 is in an open state, and the other side of the thin metal plate 1 keeps the original structure unchanged, so that a first fold 2 is formed between the other side and one side surface 12 of the thin metal plate 1.

Specifically, since the rectangular parallelepiped has a hollow structure, only the top surface, the bottom surface, and the two side surfaces are provided, and the end surfaces are not provided, that is, the two end surfaces have an open structure. One side of the thin metal plate is pressed out of the top surface and two side surfaces of the hollow cuboid, the other side of the thin metal plate is kept unchanged, because the top surface and the two side surfaces are three mutually vertical surfaces, one side surface forms an angle of 90 degrees with the side which is kept unchanged, and a first crease is formed by the intersection line of the two side surfaces. The reason why the bottom surface is not pressed out in this embodiment is that the bottom surface needs to be provided with a wrenching edge, and a connecting portion can be reserved by the wrenching edge to connect with the window sash.

S103: and pressing a second fold 3 at the edge of the other side of the thin metal plate 1 to form a first wrenching edge 5.

Specifically, after one side of the thin metal plate 1 is pressed to form the top surface 11 and two side surfaces 12 of the hollow cuboid, a first predetermined position is selected at a position close to the edge of the other side, the second fold 3 is pressed, and the first pull edge 5 is bent towards the upper surface of the side of the thin metal plate 1 to form an included angle. Wherein the upper surface of the side of the thin metal plate 1 is the upper surface of the bottom surface which is finally formed later.

S104: and pressing a third fold 4 on the other side of the thin metal plate 1 at a position close to the first fold 2, wherein a second wrenching edge 6 is formed on the surface between the first fold 2 and the third fold 4.

Specifically, after the second fold 3 is pressed on the other side of the thin metal plate 1 near the edge, a second predetermined position is selected to press a third fold 4 on the other side of the thin metal plate near the first fold 2, and the distance between the first fold 2 and the third fold 4 is the same as the width of the first wrench edge 5, that is, the width of the first wrench edge 5 is the same as the width of the second wrench edge 6.

S105: the surface of the thin metal plate 1 between the third fold 4 and the second fold 3 is defined as the bottom surface 13 of the hollow rectangular parallelepiped.

Specifically, the first pulling edge 5 and the second pulling edge 6 are both arranged at an acute angle with the upper surface of the bottom surface 13, one side surface of the hollow cuboid is connected with the second pulling edge 6 into a whole, and the other side surface is separated from the first pulling edge 5.

S106: the included angle of the first pull edge 5 and the included angle of the second pull edge 6 are welded with the upper surface of the hollow cuboid bottom surface 13, so that the first pull edge 5 and the second pull edge 6 are tightly attached to the hollow cuboid bottom surface 13.

Specifically, the term "closely attached" means that the first pulling edge corner and the second pulling edge corner are folded to be parallel to the bottom surface, so that the opening sides of the included angles are connected with the bottom surface by welding without any gap, thereby ensuring the smoothness of the two pulling edges, and when the two pulling edges are connected with the window sash, the two pulling edges are not tilted.

S107: the side surface of the hollow cuboid without the first crease 2 is welded with the bottom surface 13 to form a hollow cuboid structure with a top surface 11, a bottom surface 13 and two side surfaces 12, and the two sides of the hollow cuboid are provided with a first pulling edge 5 and a second pulling edge 6.

Specifically, as the side surface 12 of the hollow cuboid is separated from the first wrenching edge 5 and the bottom surface 13, the side surface 12 and the bottom surface 13 are welded into a whole to form a complete hollow cuboid structure, i.e. a complete mullion structure. This embodiment may connect the subframe to the first and second wrenching edges 5 and 6, so that the mullion is connected to the window sash through the subframe. Because the center mullion is a hollow cuboid structure, in order to keep the strength of the center mullion, punching on the center mullion or setting a connecting piece with a window sash is avoided, therefore, a pair of frames can be independently arranged, the pair of frames are square frames, are arranged between a window frame and the center mullion and are connected with a pull edge, connecting pieces can be arranged on the pair of frames or stepped structures are arranged on the pair of frames to be connected with the window sash, and therefore the strength and the integrity of the center mullion body are kept. The well mullion that this embodiment was made will weld with the window frame to separate into two little window frames with the window frame, all install the subframe in two little window frames, and the inboard of window frame also is provided with the limit and pulls the limit, and the subframe is connected between the limit is pulled to window frame and well mullion, wherein set up the echelonment structure with casement block looks adaptation on the subframe, and set up the connecting piece on the subframe, thereby be connected with the casement, and the casement can be followed the subframe and opened and close.

In conclusion, on one hand, the middle vertical frame is simple in structure, can be integrally formed through the thin metal plate, does not need to add other materials, is simple and convenient to operate, saves time and labor, and greatly improves the working efficiency; the connection between the window sash and the window can be realized by arranging the wrenching edge, and the connection area is increased; on the other hand, the steel is not easy to rust and has good corrosion resistance.
