Preparation process of middle vertical frame window frame

Abstract

The invention discloses a preparation process of a middle vertical frame of a window frame. The preparation process comprises the following steps that S1, a thin metal plate is taken; S2, one side ofthe thin metal plate is pressed to form a top face and two side faces of a hollow cuboid, a bottom face is open, the original structure of the other side of the thin metal plate is kept unchanged, anda first crease is formed between the other side and one side face of the thin metal plate; S3, the edge of the other side of the thin metal plate is is pressed to form a second crease, and a first pulling edge is formed; and S4, the position, close to the first crease, of the other side of the thin metal plate is pressed to form a third crease, and the face between the first crease and the thirdcrease forms a second pulling edge. On one hand, the structure is simple, the middle vertical frame can be integrally formed through the thin metal plate without adding other materials, operation is simple and convenient to conduct, time and labor are saved, and the working efficiency is greatly improved; by arranging the pulling edges, connection with a window sash can be realized, and the connection area is increased; and on the other hand, rusting is not likely to happen, and corrosion resistance is good.

Description

technical field [0001] The invention relates to a middle mullion of a window frame, in particular to a preparation process of the middle mullion of a window frame. Background technique [0002] The window comprises a window frame, a window sash and glass, the glass is arranged in the window sash, the outside of the window frame is embedded in the wall, the window sash is connected with the window frame, and the window sash can be opened along the window frame to facilitate ventilation. In order to divide the window frame into multiple small window frames to place multiple sashes and increase the ventilation effect, the middle mullion is usually set to vertically separate the window frame, so that the window frame is divided into two to form two small window frames , and then set the sash inside each small window frame. [0003] On the one hand, the existing middle mullion cannot be integrally formed by a piece of metal sheet during the processing process, and usually requir...

AI Technical Summary

Problems solved by technology

[0003] On the one hand, the existing middle mullion cannot be integrally formed by a piece of metal sheet during the processing process, and usually requires multiple processes to be formed separately, and then assembled and welded. This method not only wastes materials, but also has low work efficiency; In addition, this profile is usually directly processed to form a structure connected to the window sash, such as directly setting a connecting piece on the middle mullion or setting a stepped structure to complete the direct fit connection between the window sash and the middle mullion, which is very important for processing. Difficulty, resulting in high processing costs

On the other hand, the existing middle mullion is usually made of aluminum alloy, which is easy to rust and has poor corrosion resistance
