Problems solved by technology

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 collision, 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 the service life is not long
After the groove is installed with glass and coated with glass glue, because the gap is not completely welded, the glass glue will leak from the gap, which will affect the firmness of the glass glue to strengthen the glass

Embodiment 1

[0022] In order to realize the forming rate of metal cold pressing, the fastening and elegant appearance of welding, the present invention first improves the original metal door edge machine, and adds more forming roller molds in the cold pressing machine. First, the metal plate is flattened and pressed by two rollers with flat surfaces, and then the guide rail under the door frame is pressed by a set of roller dies along the center line of the metal plate. The guide rail is first pressed into a semicircular bow-shaped bulge, and then The guide rail is pressed into a rectangular groove by the flattening roller at the back. The pressing rollers of various shapes press slowly and step by step to maximize the standardization of the metal plate during the bending process, so that the concave and convex surfaces of the metal door frame are smooth and precise. When the metal plate enters through the entrance of the door frame cold press machine, nearly 30 rollers with different shap...

Abstract

The invention relates to the field of doorframe profiles and discloses a method for welding a doorframe profile. The method comprises the following steps of: firstly, cold-pressing and molding a metal plate in a metal doorframe machine; secondly, aligning two sides of one doorframe profile along the end parts, and trimming a seam; thirdly, aiming at the seam by using the welding gun of an argon arc welding machine to weld fully; fourthly, cooling the welded doorframe profile by using two cold water valves with a certain space; fifthly, keeping straight the cooled doorframe profile and correcting each angle; sixthly, sending to a correcting machine to correct, and finally, sending to a cutting machine to cut into doorframes with lengths as required. The invention is to provide a method for welding the doorframe profile, and the provided welding doorframe profile has no bumps and has the characteristics of attractive appearance and longer service life.

Description

technical field [0001] The invention relates to the field of door frame profiles, in particular to a welding method for door frame profiles. 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 installe...
