Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a poor connection structure of section as shown in fig. 1-6, including door plant 1, the strip 2 that bends of side, end bend strip 3, the poor strip 4 of first section and the poor strip 5 of second section, the profile of the strip 3 that bends of side bend strip 2 and end is rectangular shape platelike structure, the poor strip 5 of first section and second section sets up at the both ends of the strip 2 that bends of side.
Specifically, the door plate 1, the side bending strip 2, the end bending strip 3, the first section difference strip 4 and the second section difference strip 5 are of an integrated structure formed by shearing and bending, and the integrated structure has low manufacturing cost.
Specifically, the first section difference strip 4 and the second section difference strip 5 are formed by bending extending parts at two ends of the side bending strip 2, the side bending strip 2 and the end bending strip 3 are formed by bending edges of the door panel 1, the end bending strip 3 is bent towards the adjacent second section difference strip 5, the first section difference strip 4 and the second section difference strip 5 are staggered to solve the problem of edge welding of a traditional metal door, and connecting parts are removed from four right angles of the door, so that good corner appearance is obtained.
Specifically, end bending strip 3 and second section difference strip 5 accessible spot welding are fixed, opening self-plugging rivet is fixed and plug welding in any one mode in, and both ends and the second section difference strip 5 of end bending strip 3 have all opened rivet hole 6 when fixed through opening self-plugging rivet, and open at the both ends of end bending strip 3 when fixed through plug welding has plug welding hole 7, select suitable fixed scheme according to the manufacturing needs.
The working principle of the segment difference connecting structure is that the first segment difference strip 4 and the second segment difference strip 5 can be fixed by spot welding by adopting a process of spot welding with staggered peaks inside and outside, the connecting mode can obtain higher connecting strength, the first segment difference strip 4 and the second segment difference strip 5 are fixed by adopting the open self-plugging rivet and need to be pre-opened 6, but the fixing process of the fixing mode is quicker, the connection operation is simpler, and adopt when stopper welded fastening first section difference strip 4 and second section difference strip 5, the solder joint that the welding rod constitutes is located 7 inside and bonds first section difference strip 4 and second section difference strip 5, the solder joint will emerge from stopper welding hole 7, it can directly through the solder joint mill that the angle mill emerges grind flat, the process of polishing is comparatively easy and have good joint strength, the manufacturer can select corresponding connection scheme according to the needs of making, three kinds of connection schemes all can obtain good corner outward appearance.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
