Description
Technical Field
[0001] The utility model belongs to the technical field of door and window manufacturing, and relates to a giving way structure for seamless welding of door and window frames. Background Art
[0002] At present, door and window frames are generally formed by two opposite horizontal profiles and two opposite vertical profiles, and the end faces of both the horizontal profile and the vertical profile are 45-degree matching bevels. The horizontal profile and the vertical profile are first connected by built-in corner brackets, and then the joints after the horizontal profile and the vertical profile are connected are welded and polished. After polishing, the surface is sprayed to achieve seamless welding of door and window frames. However, during the welding process, since the corner brackets are arranged on the inner side of the joints between the horizontal profile and the vertical profile, welding gases such as argon cannot fill the entire joint, which easily leads to problems of cold welding and false welding. The frequent incomplete welding phenomenon seriously affects the quality of seamless welding of door and window frames. Summary of the invention
[0003] The purpose of the utility model is to solve the above problems in the existing technology and propose a yield structure for seamless welding of door and window frames. The technical problem to be solved by the utility model is to solve the problem that welding gas such as argon gas cannot fill the joints of horizontal profiles and vertical profiles.
[0004] The purpose of the utility model can be achieved through the following technical solutions:
[0005] A yield structure for seamless welding of door and window frames, the door and window frames comprising a plurality of profiles which can be connected to form a frame body and have plug-in interfaces at the ends. The characteristic is that the yield structure comprises a blocking protrusion arranged on the profile, the blocking protrusion is located on the inner side wall of the plug-in interface at the end of the profile, and the blocking protrusion divides the plug-in interface into a yield space located on one side of the blocking protrusion and an installation space located on the other side of the blocking protrusion.
[0006] By arranging a blocking protrusion on the inner wall of the plug-in interface at the end of the profile, the plug-in interface is divided into a makeshift space on one side of the blocking protrusion and an installation space on the other side of the blocking protrusion. The installation space can be used for inserting the corner code, while the makeshift space forms a vacant space. On the one hand, the vacant space formed by the makeshift space can allow argon and other welding gases to flow in, thereby ensuring that argon and other welding gases can fill the welding parts of the profile; on the other hand, the vacant space formed by the makeshift space can guide the direction of the welding heat flow and evacuate the welding heat in time. The combined effect of the above two factors can reduce welding stress, eliminate welding defects such as slag inclusions, pores, cracks, etc., thereby ensuring the quality of seamless welding of door and window frames.
[0007] In the above-mentioned clearance structure for seamless welding of door and window frames, there are two blocking protrusions which are arranged oppositely on the inner side wall of the insertion port at the end of the profile. The two oppositely arranged blocking protrusions can respectively abut against the two sides of the corner bracket inserted in the installation space, thereby preventing the corner bracket from entering the clearance space.
[0008] In the above-mentioned clearance structure for seamless welding of door and window frames, the side wall of the blocking protrusion close to the clearance space has an arc-shaped guide surface. The arc-shaped guide surface can guide welding gas such as argon into the clearance space on the one hand, and can increase the clearance space on the other hand, so that the clearance space can be filled with more welding gas such as argon, and the welding heat can be evacuated faster.
[0009] In the above-mentioned giving way structure for seamless welding of door and window frames, the blocking protrusion is arranged straightly near the side wall of the installation space. By arranging the blocking protrusion straightly near the side wall of the installation space, the blocking protrusion can be abutted against the corner bracket inserted in the installation space, thereby improving the reliability of the connection at the splicing of the door and window frames.
[0010] In the above-mentioned clearance structure for seamless welding of door and window frames, the blocking protrusion is integrally formed on the profile. By integrally forming the blocking protrusion on the profile, the structural strength of the blocking protrusion can be ensured, so that the blocking protrusion can better separate the plug interface into the clearance space on one side of the blocking protrusion and the installation space on the other side of the blocking protrusion.
[0011] Compared with the prior art, the advantage of the yield structure for seamless welding of door and window frames is that a blocking protrusion is provided on the inner side wall of the plug-in interface at the end of the profile, thereby dividing the plug-in interface into a yield space located on one side of the blocking protrusion and an installation space located on the other side of the blocking protrusion. The installation space can be used for inserting the corner code, while the yield space forms a vacant space. On the one hand, the vacant space formed by the yield space can allow argon and other welding gases to flow in, thereby ensuring that argon and other welding gases can fill the welding points of the profiles; on the other hand, the vacant space formed by the yield space can guide the direction of the welding heat flow and dissipate the welding heat in time. The above two factors work together to reduce welding stress, eliminate welding defects such as slag inclusions, pores, cracks, etc., thereby ensuring the quality of seamless welding of door and window frames.
