Problems solved by technology

The butt joints of the window corners made by the above two methods have the following disadvantages: 1. When the thickness of the profile cavity is too large or too small when the 45° aluminum corner code is assembled, it is impossible to ensure that the blanking thickness of the aluminum corner code is consistent with the profile cavity fit clearance
2. The firmness of the 90° self-tapping screw connection is not good, and the strength and sealing of the corner cannot be guaranteed
3. If the above two methods are improperly handled, there will be obvious butt wiring traces at the butt joints of the group corners, which not only affects the appearance, but also is easy to stick to dust

Abstract

The invention discloses a door window welding process which comprises the following steps: (1), performing cold-press moulding on a metal plate in a metal door window cold press, aligning the end parts of two edges of a door window section material, and performing fine adjustment on butt seams, wherein the tail end of the metal door window cold press is provided with a roller wheel mold with the thickness less than 2mm; (2) polishing the surface of a to-be-welded door window to remove a surface oxidation film; (3) cleaning a to-be-welded part with an acid-washing passivation solution. The invention provides the welding process of a door window which is excellent in heat-proof cycle performance, good in abrasion resistance and wearability performance, free from welded doorframe section material salient points and long in service life.

Description

technical field [0001] The invention relates to the technical field of door and window profiles, in particular to a door and window welding process. Background technique [0002] The currently known method of door frame profile welding is butt welding technology. Its operating principle is to first superimpose the two sides of the seam in the groove of the door frame, then use a butt welder to weld point by point along the gap at a certain interval. Seam to weld the seam well. Moreover, when this technology welds the groove junction of the door frame profile, many protruding and uneven solder spots will be produced. These raised solder spots will constantly rub against the glass installed in the groove when the glass door is opened and closed. And collisions, it is easy to crack the corners of the glass. In addition, the welding place of the door frame profile welded by this technology is not strong enough, easy to crack, and has a short service life. After the groove is ...
