Butt joint method for sealing flanges of door frame of stainless steel sealing door

Abstract

The invention relates to a stainless steel sealing door frame sealing flange butt joint method, a door frame is composed of four frames, a right-angle butt joint mode is adopted, stainless steel square tubes are arranged inside the frames, stainless steel wrapping plates with sealing flanges are arranged outside the frames, and the wrapping plates and a sealing door are made of the same material. The wrapping plate is made of a stainless steel plate through laser cutting and bending, and the included angle of the sealing flange can be designed into different angles. During design, the influence of material bending deformation on a butt joint line is considered, the angle and size of the butt joint line at the end of the sealing flange and the position of a bending groove are accurately designed before bending machining, after machining and manufacturing, the four corners of the two frames are in butt joint to form the butt joint line of 45 degrees or 135 degrees, and seamless and allowance-free butt joint can be achieved. The butt joint of the end parts of the sealing flange is smooth in surface and attractive in appearance, the requirement of the sealing grade of the sealing door can be met, and the market competitiveness of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical design and manufacture, and relates to a stainless steel sealed door frame, in particular to a sealing flange butt joint method of a stainless steel sealed door frame. Background technique [0002] In order to meet the sealing requirements of clean room doors, transfer windows or aqueduct transfer window doors, the sealing design and manufacture of stainless steel doors is very important. This type of door must not only meet the requirements of the sealing level, but also have a smooth surface and beautiful appearance, so as to improve the market competitiveness of the product. In the design of the airtight door, the sealing design is a very important link. It is a common sealing method to use the sealing flange around the door frame to squeeze the corresponding sealing rubber strip in the groove on the door. This method is simple, reliable and does not require Additional equipment (such as ai...

AI Technical Summary

Problems solved by technology

Due to the deformation of the steel plate due to the certain angle and bending of the sealing flange, if the influence of these factors is not considered in the design, gaps or margins are likely to occur when the ends of the sealing flanges on both sides of the four corners are docked in the manufactured cladding plate

When this kind of problem occurs, the general workers need to make partial repairs or cut and polish when making the door frame, but it is difficult to ensure the appearance of the butt joints is beautiful
