Problems solved by technology

[0002] The technical 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 and then use the butt welding machine to weld the seam along the gap at a certain interval. Many protruding and uneven solder joints will be produced when welding the groove junction of the glass door. These raised solder joints will continue to rub and collide with the glass installed in the groove when the glass door is opened and closed, which is easy to make the glass cracks in the corners
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

[0013] The door and window welding process includes the following steps: (1) cold-press forming the metal plate in the metal door and window cold-pressing machine; the tail end of the metal door and window cold-pressing machine is provided with a roller mold with a thickness Align the ends of the two edges and make minor adjustments to the seam;

[0014] (2) Grinding the surface of the doors and windows to be welded to remove the surface oxide film;

[0015] (3) Clean the parts to be welded with pickling passivation solution;

[0016] (4) Install the corner pads in the cavity of the door and window profiles and place the door and window profiles on the special clamping workbench, butt the corners, and position and press them with clamps;

[0017] (5) Argon arc welding treatment: Position the door and window profiles clamped on the workbench by spot welding; welding should start from the position of the end of the outer corner and end at the end of the inner corner, and at the...

Abstract

The invention provides a metal frame welding process. A metal plate is molded through cold pressing in a metal frame cold pressing machine; a roller mold with a thickness smaller than 2 mm is arranged at the tail end of the metal frame cold pressing machine; two edges of a door / window profile are aligned along the end parts, and joints are finely adjusted; an angle assembly cushion block is mounted in a cavity of the door / window profile, and the door / window profile is placed on a special clamping worktable, the angles are in butt joint; and a fixture is used for positioning and pressing. As an angle welding assembly mode is adopted in the metal frame welding process, and the sanding and the mold repair treatment for weld lines are performed, the profile cavity fit gap problem and the strength and sealing problems in the angle assembly butt joint places are solved, and the surfaces of the angle assembly butt joint places can be treated without traces to satisfy traditional market demands.
